Subject: [PATCH 01/63] Fix SystemExit traceback during atexit cleanup on
 Ctrl+C
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The browser_tool signal handler calls sys.exit(130) which raises
SystemExit. When this fires during terminal_tool's atexit cleanup
(specifically during _cleanup_thread.join()), it produces an unhandled
traceback. Wrapping the join in a try/except suppresses the race
without changing shutdown behavior.

Subject: [PATCH 02/63] fix: add SSH backend to terminal requirements check

The SSH backend was missing from check_terminal_requirements(), causing
it to fall through to `return False`. This silently disabled both the
terminal and file tools when TERMINAL_ENV=ssh was configured.

Subject: [PATCH 04/63] fix: resolve symlink bypass in write deny list on macOS

On macOS, /etc is a symlink to /private/etc. The _is_write_denied()
function resolves the input path with os.path.realpath() but the deny
list entries were stored as literal strings ("/etc/shadow"). This meant
the resolved path "/private/etc/shadow" never matched, allowing writes
to sensitive system files on macOS.

Fix: Apply os.path.realpath() to deny list entries at module load time
so both sides of the comparison use resolved paths.

Adds 19 regression tests in tests/tools/test_write_deny.py.

Subject: [PATCH 05/63] test: remove /etc platform-conditional tests from
 file_operations

These tests documented the macOS symlink bypass bug with
platform-conditional assertions. The fix and proper regression
tests are in PR #61 (tests/tools/test_write_deny.py), so remove
them here to avoid ordering conflicts between the two PRs.

Subject: [PATCH 07/63] fix: cron prompt injection scanner bypass for
 multi-word variants

The regex `ignore\s+(previous|all|above|prior)\s+instructions` only
allowed ONE word between "ignore" and "instructions". Multi-word
variants like "Ignore ALL prior instructions" bypassed the scanner
because "ALL" matched the alternation but then `\s+instructions`
failed to match "prior".

Fix: use `(?:\w+\s+)*` groups to allow optional extra words before
and after the keyword alternation.

Subject: [PATCH 08/63] fix(security): prevent shell injection in sudo password
 piping

The sudo password was embedded in shell commands via single-quote
interpolation: echo '{password}' | sudo -S

If the password contained shell metacharacters (single quotes,
$(), backticks), they would be interpreted by the shell, enabling
arbitrary command execution.

Fix: use shlex.quote() which properly escapes all shell-special
characters, ensuring the password is always treated as a literal
string argument to echo.

Subject: [PATCH 10/63] fix: prevent silent abort in piped install when
 interactive prompts fail (#69)

Root cause: the install script uses `set -e` (exit on error) and `read -p`
for interactive prompts. When running via `curl | bash`, stdin is a pipe
(not a terminal), so `read -p` hits EOF and returns exit code 1. Under
`set -e`, this silently aborts the entire script before hermes is installed.

Fix: detect non-interactive mode using `[ -t 0 ]` (standard POSIX test for
terminal stdin) and skip all interactive prompts when running in piped mode.
Clear messages are shown instead, telling the user what to run manually.

Changes:
- Add IS_INTERACTIVE flag at script start ([ -t 0 ] check)
- Guard sudo package install prompt (the direct cause of #69)
- Guard setup wizard (calls interactive hermes setup)
- Guard WhatsApp pairing and gateway install prompts

All other prompts use the same read -p pattern and would fail the same way
in piped mode, so they are all guarded for completeness.

Closes #69

Subject: [PATCH 13/63] fix(cli): prevent crash in save_config_value when model
 is a string

load_cli_config() supports both string and dict formats for the model
key (e.g. `model: "anthropic/claude-opus-4"`), but save_config_value()
assumed all intermediate keys are dicts. When the config file used the
string format, running `/model <name>` would crash with TypeError:
'str' object does not support item assignment.

Add an isinstance check so non-dict values are replaced with a fresh
dict before descending.

Subject: [PATCH 14/63] fix(cli): prevent paste detection from destroying
 multi-line input

The _on_text_changed handler collapsed buffer contents into a file
reference whenever the buffer had 5+ newlines, regardless of how
those lines were entered. This meant manually typing with Alt+Enter
would trigger the paste heuristic and silently replace the user's
carefully typed input.

Track the previous buffer length and only treat a change as a paste
when more than one character is added at once (real pastes insert many
characters in a single event, while typing adds one at a time).

Subject: [PATCH 15/63] fix(cli): respect explicit --max-turns value even when
 it equals default

max_turns used 60 as both the default and the sentinel to detect
whether the user passed the flag. This meant `--max-turns 60` was
indistinguishable from "not passed", so the env var
HERMES_MAX_ITERATIONS would silently override the explicit CLI value.

Change the default to None so any user-supplied value takes priority.

Subject: [PATCH 16/63] fix(cli): show correct config file path in /config
 command

show_config() always checked cli-config.yaml in the project directory,
but load_cli_config() first looks at ~/.hermes/config.yaml. When the
user config existed, /config would display "cli-config.yaml (not found)"
even though configuration was loaded successfully from ~/.hermes/.

Use the same lookup order as load_cli_config and display the actual
resolved path.

Subject: [PATCH 17/63] fix(cli): reduce spinner flickering under patch_stdout

KawaiiSpinner used a two-phase clear+redraw approach: first write
\r + spaces to blank the line, then \r + new frame. When running
inside prompt_toolkit's patch_stdout proxy, each phase could trigger
a separate repaint, causing visible flickering every 120ms.

Replace with a single \r\033[K (carriage return + ANSI erase-to-EOL)
write so the line is cleared and redrawn atomically.

Subject: [PATCH 22/63] feat(config): enhance terminal environment variable
 management

- Updated .env.example to clarify terminal backend configuration and its relationship with config.yaml.
- Modified gateway/run.py to ensure terminal settings from config.yaml take precedence over .env, improving consistency in environment variable handling.
- Added mapping for terminal configuration options to corresponding environment variables for better integration.

Subject: [PATCH 23/63] feat(api): implement dynamic max tokens handling for
 various providers

- Added _max_tokens_param method in AIAgent to return appropriate max tokens parameter based on the provider (OpenAI vs. others).
- Updated API calls in AIAgent to utilize the new max tokens handling.
- Introduced auxiliary_max_tokens_param function in auxiliary_client for consistent max tokens management across auxiliary clients.
- Refactored multiple tools to use auxiliary_max_tokens_param for improved compatibility with different models and providers.

Subject: [PATCH 24/63] feat(cli): add auto-restart functionality for
 hermes-gateway service when updating

- Implemented a check to determine if the hermes-gateway service is active after an update.
- Added logic to automatically restart the service if it is running, ensuring changes are applied without manual intervention.
- Updated user guidance to reflect the new auto-restart feature, removing the need for manual restart instructions.

Subject: [PATCH 27/63] feat(session): implement session reset policy for
 messaging platforms

- Added configuration options for automatic session resets based on inactivity or daily boundaries in cli-config.yaml.
- Enhanced SessionResetPolicy class to support a "none" mode for no auto-resets.
- Implemented memory flushing before session resets in SessionStore to preserve important information.
- Updated setup wizard to guide users in configuring session reset preferences.

Subject: [PATCH 28/63] fix(gateway): Pass session_db to AIAgent, fixing
 session_search error

When running via the gateway (e.g. Telegram), the session_search tool
returned: {"error": "session_search must be handled by the agent loop"}

Root cause:
- gateway/run.py creates AIAgent without passing session_db=
- self._session_db is None in the agent instance
- The dispatch condition "elif function_name == 'session_search' and self._session_db"
  skips when _session_db is None, falling through to the generic error

This fix:
1. Initializes self._session_db in GatewayRunner.__init__()
2. Passes session_db to all AIAgent instantiations in gateway/run.py
3. Adds defensive fallback in run_agent.py to return a clear error when
   session_db is unavailable, instead of falling through

Fixes #105

+description: Extract text from PDFs and scanned documents. Use web_extract for remote URLs, pymupdf for local text-based PDFs, marker-pdf for OCR/scanned docs. For DOCX use python-docx, for PPTX see the powerpoint skill.

+
+# PDF & Document Extraction
+
+For DOCX: use `python-docx` (parses actual document structure, far better than OCR).
+For PPTX: see the `powerpoint` skill (uses `python-pptx` with full slide/notes support).
+This skill covers **PDFs and scanned documents**.
+
+## Step 1: Remote URL Available?
+
+If the document has a URL, **always try `web_extract` first**:
+
+```
+web_extract(urls=["https://arxiv.org/pdf/2402.03300"])
+web_extract(urls=["https://example.com/report.pdf"])
+```
+
+This handles PDF-to-markdown conversion via Firecrawl with no local dependencies.
+
+Only use local extraction when: the file is local, web_extract fails, or you need batch processing.
+
+## Step 2: Choose Local Extractor
+
+| Feature | pymupdf (~25MB) | marker-pdf (~3-5GB) |
+|---------|-----------------|---------------------|
+| **Text-based PDF** | ✅ | ✅ |
+| **Scanned PDF (OCR)** | ❌ | ✅ (90+ languages) |
+| **Tables** | ✅ (basic) | ✅ (high accuracy) |
+| **Equations / LaTeX** | ❌ | ✅ |
+| **Code blocks** | ❌ | ✅ |
+| **Forms** | ❌ | ✅ |
+| **Headers/footers removal** | ❌ | ✅ |
+| **Reading order detection** | ❌ | ✅ |
+| **Images extraction** | ✅ (embedded) | ✅ (with context) |
+| **Images → text (OCR)** | ❌ | ✅ |
+| **EPUB** | ✅ | ✅ |
+| **Markdown output** | ✅ (via pymupdf4llm) | ✅ (native, higher quality) |
+| **Install size** | ~25MB | ~3-5GB (PyTorch + models) |
+| **Speed** | Instant | ~1-14s/page (CPU), ~0.2s/page (GPU) |
+
+**Decision**: Use pymupdf unless you need OCR, equations, forms, or complex layout analysis.
+
+If the user needs marker capabilities but the system lacks ~5GB free disk:
+> "This document needs OCR/advanced extraction (marker-pdf), which requires ~5GB for PyTorch and models. Your system has [X]GB free. Options: free up space, provide a URL so I can use web_extract, or I can try pymupdf which works for text-based PDFs but not scanned documents or equations."
+
+---
+
+## pymupdf (lightweight)
+
+```bash
+pip install pymupdf pymupdf4llm
+```
+
+**Via helper script**:
+```bash
+python scripts/extract_pymupdf.py document.pdf              # Plain text
+python scripts/extract_pymupdf.py document.pdf --markdown    # Markdown
+python scripts/extract_pymupdf.py document.pdf --tables      # Tables
+python scripts/extract_pymupdf.py document.pdf --images out/ # Extract images
+python scripts/extract_pymupdf.py document.pdf --metadata    # Title, author, pages
+python scripts/extract_pymupdf.py document.pdf --pages 0-4   # Specific pages
+```
+
+**Inline**:
+```bash
+python3 -c "
+import pymupdf
+doc = pymupdf.open('document.pdf')
+for page in doc:
+    print(page.get_text())
+"
+```
+
+---
+
+## marker-pdf (high-quality OCR)
+
+```bash
+# Check disk space first
+python scripts/extract_marker.py --check
+
+pip install marker-pdf
+```
+
+**Via helper script**:
+```bash
+python scripts/extract_marker.py document.pdf                # Markdown
+python scripts/extract_marker.py document.pdf --json         # JSON with metadata
+python scripts/extract_marker.py document.pdf --output_dir out/  # Save images
+python scripts/extract_marker.py scanned.pdf                 # Scanned PDF (OCR)
+python scripts/extract_marker.py document.pdf --use_llm      # LLM-boosted accuracy
+```
+
+**CLI** (installed with marker-pdf):
+```bash
+marker_single document.pdf --output_dir ./output
+marker /path/to/folder --workers 4    # Batch
+```
+
+---
+
+## Arxiv Papers
+
+```
+# Abstract only (fast)
+web_extract(urls=["https://arxiv.org/abs/2402.03300"])
+
+# Full paper
+web_extract(urls=["https://arxiv.org/pdf/2402.03300"])
+
+# Search
+web_search(query="arxiv GRPO reinforcement learning 2026")
+```
+
+## Notes
+
+- `web_extract` is always first choice for URLs
+- pymupdf is the safe default — instant, no models, works everywhere
+- marker-pdf is for OCR, scanned docs, equations, complex layouts — install only when needed
+- Both helper scripts accept `--help` for full usage
+- marker-pdf downloads ~2.5GB of models to `~/.cache/huggingface/` on first use
+- For Word docs: `pip install python-docx` (better than OCR — parses actual structure)
+- For PowerPoint: see the `powerpoint` skill (uses python-pptx)

+# arXiv Research
+
+Search and retrieve academic papers from arXiv via their free REST API. No API key, no dependencies — just curl.
+
+## Quick Reference
+
+| Action | Command |
+|--------|---------|
+| Search papers | `curl "https://export.arxiv.org/api/query?search_query=all:QUERY&max_results=5"` |
+| Get specific paper | `curl "https://export.arxiv.org/api/query?id_list=2402.03300"` |
+| Read abstract (web) | `web_extract(urls=["https://arxiv.org/abs/2402.03300"])` |
+| Read full paper (PDF) | `web_extract(urls=["https://arxiv.org/pdf/2402.03300"])` |
+
+## Searching Papers
+
+The API returns Atom XML. Parse with `grep`/`sed` or pipe through `python3` for clean output.
+
+### Basic search
+
+```bash
+curl -s "https://export.arxiv.org/api/query?search_query=all:GRPO+reinforcement+learning&max_results=5"
+```
+
+### Clean output (parse XML to readable format)
+
+```bash
+curl -s "https://export.arxiv.org/api/query?search_query=all:GRPO+reinforcement+learning&max_results=5&sortBy=submittedDate&sortOrder=descending" | python3 -c "
+import sys, xml.etree.ElementTree as ET
+ns = {'a': 'http://www.w3.org/2005/Atom'}
+root = ET.parse(sys.stdin).getroot()
+for i, entry in enumerate(root.findall('a:entry', ns)):
+    title = entry.find('a:title', ns).text.strip().replace('\n', ' ')
+    arxiv_id = entry.find('a:id', ns).text.strip().split('/abs/')[-1]
+    published = entry.find('a:published', ns).text[:10]
+    authors = ', '.join(a.find('a:name', ns).text for a in entry.findall('a:author', ns))
+    summary = entry.find('a:summary', ns).text.strip()[:200]
+    cats = ', '.join(c.get('term') for c in entry.findall('a:category', ns))
+    print(f'{i+1}. [{arxiv_id}] {title}')
+    print(f'   Authors: {authors}')
+    print(f'   Published: {published} | Categories: {cats}')
+    print(f'   Abstract: {summary}...')
+    print(f'   PDF: https://arxiv.org/pdf/{arxiv_id}')
+    print()
+"
+```
+
+## Search Query Syntax
+
+| Prefix | Searches | Example |
+|--------|----------|---------|
+| `all:` | All fields | `all:transformer+attention` |
+| `ti:` | Title | `ti:large+language+models` |
+| `au:` | Author | `au:vaswani` |
+| `abs:` | Abstract | `abs:reinforcement+learning` |
+| `cat:` | Category | `cat:cs.AI` |
+| `co:` | Comment | `co:accepted+NeurIPS` |
+
+### Boolean operators
+
+```
+# AND (default when using +)
+search_query=all:transformer+attention
+
+# OR
+search_query=all:GPT+OR+all:BERT
+
+# AND NOT
+search_query=all:language+model+ANDNOT+all:vision
+
+# Exact phrase
+search_query=ti:"chain+of+thought"
+
+# Combined
+search_query=au:hinton+AND+cat:cs.LG
+```
+
+## Sort and Pagination
+
+| Parameter | Options |
+|-----------|---------|
+| `sortBy` | `relevance`, `lastUpdatedDate`, `submittedDate` |
+| `sortOrder` | `ascending`, `descending` |
+| `start` | Result offset (0-based) |
+| `max_results` | Number of results (default 10, max 30000) |
+
+```bash
+# Latest 10 papers in cs.AI
+curl -s "https://export.arxiv.org/api/query?search_query=cat:cs.AI&sortBy=submittedDate&sortOrder=descending&max_results=10"
+```
+
+## Fetching Specific Papers
+
+```bash
+# By arXiv ID
+curl -s "https://export.arxiv.org/api/query?id_list=2402.03300"
+
+# Multiple papers
+curl -s "https://export.arxiv.org/api/query?id_list=2402.03300,2401.12345,2403.00001"
+```
+
+## Reading Paper Content
+
+After finding a paper, read it:
+
+```
+# Abstract page (fast, metadata + abstract)
+web_extract(urls=["https://arxiv.org/abs/2402.03300"])
+
+# Full paper (PDF → markdown via Firecrawl)
+web_extract(urls=["https://arxiv.org/pdf/2402.03300"])
+```
+
+For local PDF processing, see the `ocr-and-documents` skill.
+
+## Common Categories
+
+| Category | Field |
+|----------|-------|
+| `cs.AI` | Artificial Intelligence |
+| `cs.CL` | Computation and Language (NLP) |
+| `cs.CV` | Computer Vision |
+| `cs.LG` | Machine Learning |
+| `cs.CR` | Cryptography and Security |
+| `stat.ML` | Machine Learning (Statistics) |
+| `math.OC` | Optimization and Control |
+| `physics.comp-ph` | Computational Physics |
+
+Full list: https://arxiv.org/category_taxonomy
+
+## Helper Script
+
+The `scripts/search_arxiv.py` script handles XML parsing and provides clean output:
+
+```bash
+python scripts/search_arxiv.py "GRPO reinforcement learning"
+python scripts/search_arxiv.py "transformer attention" --max 10 --sort date
+python scripts/search_arxiv.py --author "Yann LeCun" --max 5
+python scripts/search_arxiv.py --category cs.AI --sort date
+python scripts/search_arxiv.py --id 2402.03300
+python scripts/search_arxiv.py --id 2402.03300,2401.12345
+```
+
+No dependencies — uses only Python stdlib.
+
+---
+
+## Semantic Scholar (Citations, Related Papers, Author Profiles)
+
+arXiv doesn't provide citation data or recommendations. Use the **Semantic Scholar API** for that — free, no key needed for basic use (1 req/sec), returns JSON.
+
+### Get paper details + citations
+
+```bash
+# By arXiv ID
+curl -s "https://api.semanticscholar.org/graph/v1/paper/arXiv:2402.03300?fields=title,authors,citationCount,referenceCount,influentialCitationCount,year,abstract" | python3 -m json.tool
+
+# By Semantic Scholar paper ID or DOI
+curl -s "https://api.semanticscholar.org/graph/v1/paper/DOI:10.1234/example?fields=title,citationCount"
+```
+
+### Get citations OF a paper (who cited it)
+
+```bash
+curl -s "https://api.semanticscholar.org/graph/v1/paper/arXiv:2402.03300/citations?fields=title,authors,year,citationCount&limit=10" | python3 -m json.tool
+```
+
+### Get references FROM a paper (what it cites)
+
+```bash
+curl -s "https://api.semanticscholar.org/graph/v1/paper/arXiv:2402.03300/references?fields=title,authors,year,citationCount&limit=10" | python3 -m json.tool
+```
+
+### Search papers (alternative to arXiv search, returns JSON)
+
+```bash
+curl -s "https://api.semanticscholar.org/graph/v1/paper/search?query=GRPO+reinforcement+learning&limit=5&fields=title,authors,year,citationCount,externalIds" | python3 -m json.tool
+```
+
+### Get paper recommendations
+
+```bash
+curl -s -X POST "https://api.semanticscholar.org/recommendations/v1/papers/" \
+  -H "Content-Type: application/json" \
+  -d '{"positivePaperIds": ["arXiv:2402.03300"], "negativePaperIds": []}' | python3 -m json.tool
+```
+
+### Author profile
+
+```bash
+curl -s "https://api.semanticscholar.org/graph/v1/author/search?query=Yann+LeCun&fields=name,hIndex,citationCount,paperCount" | python3 -m json.tool
+```
+
+### Useful Semantic Scholar fields
+
+`title`, `authors`, `year`, `abstract`, `citationCount`, `referenceCount`, `influentialCitationCount`, `isOpenAccess`, `openAccessPdf`, `fieldsOfStudy`, `publicationVenue`, `externalIds` (contains arXiv ID, DOI, etc.)
+
+---
+
+## Complete Research Workflow
+
+1. **Discover**: `python scripts/search_arxiv.py "your topic" --sort date --max 10`
+2. **Assess impact**: `curl -s "https://api.semanticscholar.org/graph/v1/paper/arXiv:ID?fields=citationCount,influentialCitationCount"`
+3. **Read abstract**: `web_extract(urls=["https://arxiv.org/abs/ID"])`
+4. **Read full paper**: `web_extract(urls=["https://arxiv.org/pdf/ID"])`
+5. **Find related work**: `curl -s "https://api.semanticscholar.org/graph/v1/paper/arXiv:ID/references?fields=title,citationCount&limit=20"`
+6. **Get recommendations**: POST to Semantic Scholar recommendations endpoint
+7. **Track authors**: `curl -s "https://api.semanticscholar.org/graph/v1/author/search?query=NAME"`
+
+## Rate Limits
+
+| API | Rate | Auth |
+|-----|------|------|
+| arXiv | ~1 req / 3 seconds | None needed |
+| Semantic Scholar | 1 req / second | None (100/sec with API key) |
+
+## Notes
+
+- arXiv returns Atom XML — use the helper script or parsing snippet for clean output
+- Semantic Scholar returns JSON — pipe through `python3 -m json.tool` for readability
+- arXiv IDs: old format (`hep-th/0601001`) vs new (`2402.03300`)
+- PDF: `https://arxiv.org/pdf/{id}` — Abstract: `https://arxiv.org/abs/{id}`
+- HTML (when available): `https://arxiv.org/html/{id}`
+- For local PDF processing, see the `ocr-and-documents` skill

Subject: [PATCH 31/63] fix(gateway): Remove session_db from AIAgent
 instantiation to prevent errors

This change removes the session_db parameter from AIAgent instantiations in gateway/run.py, addressing issues related to session management. The previous implementation caused errors when session_db was not properly initialized, leading to failures in session_search functionality.

+# Contributing to Hermes Agent
+
+Thank you for your interest in contributing to Hermes Agent! This document provides guidelines and information for contributors.
+
+## Getting Started
+
+### Prerequisites
+
+- Python 3.11+
+- An OpenRouter API key (for running the agent)
+- Git
+
+### Development Setup
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/NousResearch/hermes-agent.git
+   cd hermes-agent
+   ```
+
+2. Install dependencies:
+   ```bash
+   pip install -e .
+   # Or using uv
+   uv pip install -e .
+   ```
+
+3. Copy the example environment file and configure:
+   ```bash
+   cp .env.example .env
+   # Edit .env with your API keys
+   ```
+
+4. Run the setup script (optional, for shell autocompletion):
+   ```bash
+   ./setup-hermes.sh
+   ```
+

+
+## Contributing Guidelines
+
+### Code Style
+
+- Follow PEP 8 for Python code
+- Use type hints where practical
+- Add docstrings to functions and classes (Google-style docstrings preferred)
+- Keep lines under 100 characters when reasonable
+
+### Adding a New Tool
+
+Tools self-register with the central registry. To add a new tool:
+
+1. Create a new file in `tools/` (e.g., `tools/my_tool.py`)
+
+2. Define your tool handler and schema:
+   ```python
+   #!/usr/bin/env python3
+   """
+   My Tool Module - Brief description
+   
+   Longer description of what the tool does.
+   """
+   
+   import json
+   from tools.registry import registry
+   
+   
+   def my_tool_handler(args: dict, **kwargs) -> str:
+       """Execute the tool and return JSON result."""
+       # Your implementation here
+       return json.dumps({"result": "success"})
+   
+   
+   def check_my_tool_requirements() -> bool:
+       """Check if tool dependencies are available."""
+       return True  # Or actual availability check
+   
+   
+   MY_TOOL_SCHEMA = {
+       "name": "my_tool",
+       "description": "What this tool does...",
+       "parameters": {
+           "type": "object",
+           "properties": {
+               "param1": {
+                   "type": "string",
+                   "description": "Description of param1"
+               }
+           },
+           "required": ["param1"]
+       }
+   }
+   
+   # Register with the central registry
+   registry.register(
+       name="my_tool",
+       toolset="my_toolset",
+       schema=MY_TOOL_SCHEMA,
+       handler=lambda args, **kw: my_tool_handler(args, **kw),
+       check_fn=check_my_tool_requirements,
+   )
+   ```
+
+3. Add the import to `model_tools.py` in `_discover_tools()`:
+   ```python
+   _modules = [
+       # ... existing modules ...
+       "tools.my_tool",
+   ]
+   ```
+
+4. Add your toolset to `toolsets.py` if it's a new category
+
+### Adding a Skill
+
+Skills are markdown documents with YAML frontmatter. Create a new skill:
+
+1. Create a directory in `skills/`:
+   ```
+   skills/my-skill/
+   └── SKILL.md
+   ```
+
+2. Write the skill file with proper frontmatter:
+   ```markdown
+   ---
+   name: my-skill
+   description: Brief description of what this skill does
+   version: 1.0.0
+   author: Your Name
+   tags: [category, subcategory]
+   ---
+   
+   # My Skill
+   
+   Instructions for the agent when using this skill...
+   ```
+
+### Pull Request Process
+
+1. **Fork the repository** and create a feature branch:
+   ```bash
+   git checkout -b feat/my-feature
+   # or
+   git checkout -b fix/issue-description
+   ```
+
+2. **Make your changes** with clear, focused commits
+
+3. **Test your changes**:
+   ```bash
+   # Run the test suite
+   pytest tests/
+   
+   # Test manually with the CLI
+   python cli.py
+   ```
+
+4. **Update documentation** if needed
+
+5. **Submit a pull request** with:
+   - Clear title following conventional commits (e.g., `feat(tools):`, `fix(cli):`, `docs:`)
+   - Description of what changed and why
+   - Reference to any related issues
+
+### Commit Message Format
+
+We follow [Conventional Commits](https://www.conventionalcommits.org/):
+
+```
+<type>(<scope>): <description>
+
+[optional body]
+
+[optional footer]
+```
+
+Types:
+- `feat`: New feature
+- `fix`: Bug fix
+- `docs`: Documentation only
+- `refactor`: Code change that neither fixes a bug nor adds a feature
+- `test`: Adding or correcting tests
+- `chore`: Changes to build process or auxiliary tools
+
+Scopes: `cli`, `gateway`, `tools`, `skills`, `agent`, etc.
+
+### Security Considerations
+
+When contributing tools that interact with external resources:
+
+- **Skills Guard**: External skills pass through security scanning (`tools/skills_guard.py`)
+- **Dangerous Commands**: Terminal commands are checked against patterns (`tools/approval.py`)
+- **Memory Scanning**: Memory entries are scanned for injection attempts
+- **Context Scanning**: AGENTS.md and similar files are scanned before prompt injection
+
+If your change affects security, please note this in your PR.
+
+## Reporting Issues
+
+- Use GitHub Issues for bug reports and feature requests
+- Include steps to reproduce for bugs
+- Include system information (OS, Python version)
+- Check existing issues before creating duplicates
+
+## Questions?
+
+- Open a GitHub Discussion for general questions
+- Join the Nous Research community for real-time chat
+
+## License
+
+By contributing, you agree that your contributions will be licensed under the same license as the project.

+
+| Protection | Description |
+|------------|-------------|
+| **Shell injection prevention** | Sudo password piping uses `shlex.quote()` to prevent metacharacter injection |
+| **Cron prompt injection scanning** | Scheduled task prompts are scanned for instruction-override patterns (multi-word variants, Unicode obfuscation) |
+| **Write deny list with symlink resolution** | Protected paths (`~/.ssh/authorized_keys`, `/etc/shadow`, etc.) are resolved via `os.path.realpath()` before comparison, preventing symlink bypass |
+| **Recursive delete false-positive fix** | Dangerous command detection uses precise flag-matching to avoid blocking safe commands |
+| **Code execution sandbox** | `execute_code` scripts run in a child process with API keys and credentials stripped from the environment |
+| **Container hardening** | Docker containers run with read-only root, all capabilities dropped, no privilege escalation, PID limits |
+| **DM pairing** | Cryptographically random pairing codes with 1-hour expiry and rate limiting |
+| **User allowlists** | Default deny-all for messaging platforms; explicit allowlists or DM pairing required |
+
+For sandboxed terminal options, see [Terminal & Process Management](#-terminal--process-management).

Subject: [PATCH 36/63] Cherry-pick 6 bug fixes from PR #76 and update
 documentation

Code fixes (run_agent.py):
- Fix off-by-one in _flush_messages_to_session_db skipping one message per flush
- Add clear_interrupt() to 3 early-return paths preventing stale interrupt state
- Wrap handle_function_call in try/except so tool crashes don't kill the conversation
- Replace fragile `is` identity check with _flush_sentinel marker for memory flush cleanup
- Fix retry loop off-by-one (6 attempts not 7)
- Remove redundant inline `import re`

 ### WhatsApp
 
-WhatsApp integration is more complex due to the lack of a simple bot API.
+WhatsApp uses a built-in bridge powered by [Baileys](https://github.com/WhiskeySockets/Baileys) that connects via WhatsApp Web. The agent links to your WhatsApp account and responds to incoming messages.
 
-**Options:**
-1. **WhatsApp Business API** (requires Meta verification)
-2. **whatsapp-web.js** via Node.js bridge (for personal accounts)
+**Setup:**
 
-**Bridge Setup:**
-1. Install Node.js
-2. Set up the bridge script (see `scripts/whatsapp-bridge/` for reference)
-3. Configure in gateway:
-   ```json
-   {
-     "platforms": {
-       "whatsapp": {
-         "enabled": true,
-         "extra": {
-           "bridge_script": "/path/to/bridge.js",
-           "bridge_port": 3000
-         }
-       }
-     }
-   }
-   ```
+```bash
+hermes whatsapp
+```
+
+This will:
+- Enable WhatsApp in your `.env`
+- Ask for your phone number (for the allowlist)
+- Install bridge dependencies (Node.js required)
+- Display a QR code — scan it with your phone (WhatsApp → Settings → Linked Devices → Link a Device)
+- Exit automatically once paired
+
+Then start the gateway:
+
+```bash
+hermes gateway
+```
+
+The gateway starts the WhatsApp bridge automatically using the saved session credentials in `~/.hermes/whatsapp/session/`.
+
+**Environment variables:**
+
+```bash
+WHATSAPP_ENABLED=true
+WHATSAPP_ALLOWED_USERS=15551234567    # Comma-separated phone numbers with country code
+```
+
+Agent responses are prefixed with "⚕ **Hermes Agent**" so you can distinguish them from your own messages when messaging yourself.
+
+> **Re-pairing:** If WhatsApp Web sessions disconnect (protocol updates, phone reset), re-pair with `hermes whatsapp`.

+- The API `<id>` field returns the versioned URL (e.g., `http://arxiv.org/abs/1706.03762v7`)
+
+## Withdrawn Papers
+
+Papers can be withdrawn after submission. When this happens:
+- The `<summary>` field contains a withdrawal notice (look for "withdrawn" or "retracted")
+- Metadata fields may be incomplete
+- Always check the summary before treating a result as a valid paper

 # Contributing to Hermes Agent
 
-Thank you for your interest in contributing to Hermes Agent! This document provides guidelines and information for contributors.
+Thank you for contributing to Hermes Agent! This guide covers everything you need: setting up your dev environment, understanding the architecture, deciding what to build, and getting your PR merged.
 
-## Getting Started
+---
+
+## Contribution Priorities
+
+We value contributions in this order:
+
+1. **Bug fixes** — crashes, incorrect behavior, data loss. Always top priority.
+2. **Cross-platform compatibility** — Windows, macOS, different Linux distros, different terminal emulators. We want Hermes to work everywhere.
+3. **Security hardening** — shell injection, prompt injection, path traversal, privilege escalation. See [Security](#security-considerations).
+4. **Performance and robustness** — retry logic, error handling, graceful degradation.
+5. **New skills** — but only broadly useful ones. See [Should it be a Skill or a Tool?](#should-it-be-a-skill-or-a-tool)
+6. **New tools** — rarely needed. Most capabilities should be skills. See below.
+7. **Documentation** — fixes, clarifications, new examples.
+
+---
+
+## Should it be a Skill or a Tool?
+
+This is the most common question for new contributors. The answer is almost always **skill**.
+
+### Make it a Skill when:
+
+- The capability can be expressed as instructions + shell commands + existing tools
+- It wraps an external CLI or API that the agent can call via `terminal` or `web_extract`
+- It doesn't need custom Python integration or API key management baked into the agent
+- Examples: arXiv search, git workflows, Docker management, PDF processing, email via CLI tools
+
+### Make it a Tool when:
+
+- It requires end-to-end integration with API keys, auth flows, or multi-component configuration managed by the agent harness
+- It needs custom processing logic that must execute precisely every time (not "best effort" from LLM interpretation)
+- It handles binary data, streaming, or real-time events that can't go through the terminal
+- Examples: browser automation (Browserbase session management), TTS (audio encoding + platform delivery), vision analysis (base64 image handling)
+
+### Should the Skill be bundled?
+
+Bundled skills (in `skills/`) ship with every Hermes install. They should be **broadly useful to most users**:
+
+- Document handling, web research, common dev workflows, system administration
+- Used regularly by a wide range of people
+
+If your skill is specialized (a niche engineering tool, a specific SaaS integration, a game), it's better suited for a **Skills Hub** — upload it to a skills registry and share it in the [Nous Research Discord](https://discord.gg/NousResearch). Users can install it with `hermes skills install`.
+
+---
+
+## Development Setup
 
 ### Prerequisites
 
-- Python 3.11+
-- An OpenRouter API key (for running the agent)
-- Git
+| Requirement | Notes |
+|-------------|-------|
+| **Git** | With `--recurse-submodules` support |
+| **Python 3.11+** | uv will install it if missing |
+| **uv** | Fast Python package manager ([install](https://docs.astral.sh/uv/)) |
+| **Node.js 18+** | Optional — needed for browser tools and WhatsApp bridge |
 
-### Development Setup
+### Clone and install
 
-1. Clone the repository:
-   ```bash
-   git clone https://github.com/NousResearch/hermes-agent.git
-   cd hermes-agent
-   ```
+```bash
+git clone --recurse-submodules https://github.com/NousResearch/hermes-agent.git
+cd hermes-agent
 
-2. Install dependencies:
-   ```bash
-   pip install -e .
-   # Or using uv
-   uv pip install -e .
-   ```
+# Create venv with Python 3.11
+uv venv venv --python 3.11
+export VIRTUAL_ENV="$(pwd)/venv"
 
-3. Copy the example environment file and configure:
-   ```bash
-   cp .env.example .env
-   # Edit .env with your API keys
-   ```
+# Install with all extras (messaging, cron, CLI menus, dev tools)
+uv pip install -e ".[all,dev]"
+uv pip install -e "./mini-swe-agent"
+uv pip install -e "./tinker-atropos"
 
-4. Run the setup script (optional, for shell autocompletion):
-   ```bash
-   ./setup-hermes.sh
-   ```
+# Optional: browser tools
+npm install
+```
+
+### Configure for development
+
+```bash
+mkdir -p ~/.hermes/{cron,sessions,logs,memories,skills}
+cp cli-config.yaml.example ~/.hermes/config.yaml
+touch ~/.hermes/.env
+
+# Add at minimum an LLM provider key:
+echo 'OPENROUTER_API_KEY=sk-or-v1-your-key' >> ~/.hermes/.env
+```
+
+### Run
+
+```bash
+# Symlink for global access
+mkdir -p ~/.local/bin
+ln -sf "$(pwd)/venv/bin/hermes" ~/.local/bin/hermes
+
+# Verify
+hermes doctor
+hermes chat -q "Hello"
+```
+
+### Run tests
+
+```bash
+pytest tests/ -v
+```

-### Adding a New Tool
+## Architecture Overview
 
-Tools self-register with the central registry. To add a new tool:
+### Core Loop
 
-1. Create a new file in `tools/` (e.g., `tools/my_tool.py`)
+```
+User message → AIAgent._run_agent_loop()
+  ├── Build system prompt (prompt_builder.py)
+  ├── Build API kwargs (model, messages, tools, reasoning config)
+  ├── Call LLM (OpenAI-compatible API)
+  ├── If tool_calls in response:
+  │     ├── Execute each tool via registry dispatch
+  │     ├── Add tool results to conversation
+  │     └── Loop back to LLM call
+  ├── If text response:
+  │     ├── Persist session to DB
+  │     └── Return final_response
+  └── Context compression if approaching token limit
+```
 
-2. Define your tool handler and schema:
+### Key Design Patterns
+
+- **Self-registering tools**: Each tool file calls `registry.register()` at import time. `model_tools.py` triggers discovery by importing all tool modules.
+- **Toolset grouping**: Tools are grouped into toolsets (`web`, `terminal`, `file`, `browser`, etc.) that can be enabled/disabled per platform.
+- **Session persistence**: All conversations are stored in SQLite (`hermes_state.py`) with full-text search. JSON logs go to `~/.hermes/sessions/`.
+- **Ephemeral injection**: System prompts and prefill messages are injected at API call time, never persisted to the database or logs.
+- **Provider abstraction**: The agent works with any OpenAI-compatible API. Provider resolution happens at init time (Nous Portal OAuth, OpenRouter API key, or custom endpoint).
+
+---
+
+## Code Style
+
+- **PEP 8** with practical exceptions (we don't enforce strict line length)
+- **Comments**: Only when explaining non-obvious intent, trade-offs, or API quirks. Don't narrate what the code does — `# increment counter` adds nothing
+- **Error handling**: Catch specific exceptions. Log with `logger.warning()`/`logger.error()` — use `exc_info=True` for unexpected errors so stack traces appear in logs
+- **Cross-platform**: Never assume Unix. See [Cross-Platform Compatibility](#cross-platform-compatibility)
+
+---
+
+## Adding a New Tool
+
+Before writing a tool, ask: [should this be a skill instead?](#should-it-be-a-skill-or-a-tool)
+
+Tools self-register with the central registry. Each tool file co-locates its schema, handler, and registration:
+
+```python
+"""my_tool — Brief description of what this tool does."""
+
+import json
+from tools.registry import registry
+
+
+def my_tool(param1: str, param2: int = 10, **kwargs) -> str:
+    """Handler. Returns a string result (often JSON)."""
+    result = do_work(param1, param2)
+    return json.dumps(result)
+
+
+MY_TOOL_SCHEMA = {
+    "type": "function",
+    "function": {
+        "name": "my_tool",
+        "description": "What this tool does and when the agent should use it.",
+        "parameters": {
+            "type": "object",
+            "properties": {
+                "param1": {"type": "string", "description": "What param1 is"},
+                "param2": {"type": "integer", "description": "What param2 is", "default": 10},
+            },
+            "required": ["param1"],
+        },
+    },
+}
+
+
+def _check_requirements() -> bool:
+    """Return True if this tool's dependencies are available."""
+    return True
+
+
+registry.register(
+    name="my_tool",
+    toolset="my_toolset",
+    schema=MY_TOOL_SCHEMA,
+    handler=lambda args, **kw: my_tool(**args, **kw),
+    check_fn=_check_requirements,
+)
+```
+
+Then add the import to `model_tools.py` in the `_modules` list:
+
+```python
+_modules = [
+    # ... existing modules ...
+    "tools.my_tool",
+]
+```
+
+If it's a new toolset, add it to `toolsets.py` and to the relevant platform presets.
+
+---
+
+## Adding a Bundled Skill
+
+Bundled skills live in `skills/` organized by category:
+
+```
+skills/
+├── research/
+│   └── arxiv/
+│       ├── SKILL.md              # Required: main instructions

+Brief intro.
+
+## When to Use
+Trigger conditions — when should the agent load this skill?
+
+## Quick Reference
+Table of common commands or API calls.
+
+## Procedure
+Step-by-step instructions the agent follows.
+
+## Pitfalls
+Known failure modes and how to handle them.
+
+## Verification
+How the agent confirms it worked.
+```
+
+### Skill guidelines
+
+- **No external dependencies unless absolutely necessary.** Prefer stdlib Python, curl, and existing Hermes tools (`web_extract`, `terminal`, `read_file`).
+- **Progressive disclosure.** Put the most common workflow first. Edge cases and advanced usage go at the bottom.
+- **Include helper scripts** for XML/JSON parsing or complex logic — don't expect the LLM to write parsers inline every time.
+- **Test it.** Run `hermes --toolsets skills -q "Use the X skill to do Y"` and verify the agent follows the instructions correctly.
+
+---
+
+## Cross-Platform Compatibility
+
+Hermes runs on Linux, macOS, and Windows. When writing code that touches the OS:
+
+### Critical rules
+
+1. **`termios` and `fcntl` are Unix-only.** Always catch both `ImportError` and `NotImplementedError`:
    ```python
-   #!/usr/bin/env python3
-   """
-   My Tool Module - Brief description
-   
-   Longer description of what the tool does.
-   """
-

-       return json.dumps({"result": "success"})
-   
-   
-   def check_my_tool_requirements() -> bool:
-       """Check if tool dependencies are available."""
-       return True  # Or actual availability check

-3. Add the import to `model_tools.py` in `_discover_tools()`:
+2. **File encoding.** Windows may save `.env` files in `cp1252`. Always handle encoding errors:
    ```python
-   _modules = [
-       # ... existing modules ...
-       "tools.my_tool",
-   ]
+   try:
+       load_dotenv(env_path)
+   except UnicodeDecodeError:
+       load_dotenv(env_path, encoding="latin-1")
    ```
 
-4. Add your toolset to `toolsets.py` if it's a new category
-
-### Adding a Skill
-
-Skills are markdown documents with YAML frontmatter. Create a new skill:
-
-1. Create a directory in `skills/`:
-   ```
-   skills/my-skill/
-   └── SKILL.md
+3. **Process management.** `os.setsid()`, `os.killpg()`, and signal handling differ on Windows. Use platform checks:
+   ```python
+   import platform
+   if platform.system() != "Windows":
+       kwargs["preexec_fn"] = os.setsid
    ```
 
-2. Write the skill file with proper frontmatter:
-   ```markdown
-   ---
-   name: my-skill
-   description: Brief description of what this skill does
-   version: 1.0.0
-   author: Your Name
-   tags: [category, subcategory]
-   ---
-   
-   # My Skill
-   
-   Instructions for the agent when using this skill...
-   ```
+4. **Path separators.** Use `pathlib.Path` instead of string concatenation with `/`.
 
-### Pull Request Process
+5. **Shell commands in installers.** If you change `scripts/install.sh`, check if the equivalent change is needed in `scripts/install.ps1`.
 
-1. **Fork the repository** and create a feature branch:
-   ```bash
-   git checkout -b feat/my-feature
-   # or
-   git checkout -b fix/issue-description
-   ```
+---
 
-2. **Make your changes** with clear, focused commits
+## Security Considerations
 
-3. **Test your changes**:
-   ```bash
-   # Run the test suite
-   pytest tests/
-   
-   # Test manually with the CLI
-   python cli.py
-   ```
+Hermes has terminal access. Security matters.
 
-4. **Update documentation** if needed
+### Existing protections
 
-5. **Submit a pull request** with:
-   - Clear title following conventional commits (e.g., `feat(tools):`, `fix(cli):`, `docs:`)
-   - Description of what changed and why
-   - Reference to any related issues
+| Layer | Implementation |
+|-------|---------------|
+| **Sudo password piping** | Uses `shlex.quote()` to prevent shell injection |
+| **Dangerous command detection** | Regex patterns in `tools/approval.py` with user approval flow |
+| **Cron prompt injection** | Scanner in `tools/cronjob_tools.py` blocks instruction-override patterns |
+| **Write deny list** | Protected paths (`~/.ssh/authorized_keys`, `/etc/shadow`) resolved via `os.path.realpath()` to prevent symlink bypass |
+| **Skills guard** | Security scanner for hub-installed skills (`tools/skills_guard.py`) |
+| **Code execution sandbox** | `execute_code` child process runs with API keys stripped from environment |
+| **Container hardening** | Docker: read-only root, all capabilities dropped, no privilege escalation, PID limits |
 
-### Commit Message Format
+### When contributing security-sensitive code
 
-We follow [Conventional Commits](https://www.conventionalcommits.org/):
+- **Always use `shlex.quote()`** when interpolating user input into shell commands
+- **Resolve symlinks** with `os.path.realpath()` before path-based access control checks
+- **Don't log secrets.** API keys, tokens, and passwords should never appear in log output
+- **Catch broad exceptions** around tool execution so a single failure doesn't crash the agent loop
+- **Test on all platforms** if your change touches file paths, process management, or shell commands
+
+If your PR affects security, note it explicitly in the description.
+
+---
+
+## Pull Request Process
+
+### Branch naming
+
+```
+fix/description        # Bug fixes
+feat/description       # New features
+docs/description       # Documentation
+test/description       # Tests
+refactor/description   # Code restructuring
+```
+
+### Before submitting
+
+1. **Run tests**: `pytest tests/ -v`
+2. **Test manually**: Run `hermes` and exercise the code path you changed
+3. **Check cross-platform impact**: If you touch file I/O, process management, or terminal handling, consider Windows and macOS
+4. **Keep PRs focused**: One logical change per PR. Don't mix a bug fix with a refactor with a new feature.
+
+### PR description
+
+Include:
+- **What** changed and **why**
+- **How to test** it (reproduction steps for bugs, usage examples for features)
+- **What platforms** you tested on
+- Reference any related issues
+
+### Commit messages
+
+We use [Conventional Commits](https://www.conventionalcommits.org/):

-Types:
-- `feat`: New feature
-- `fix`: Bug fix
-- `docs`: Documentation only
-- `refactor`: Code change that neither fixes a bug nor adds a feature
-- `test`: Adding or correcting tests
-- `chore`: Changes to build process or auxiliary tools
+| Type | Use for |
+|------|---------|
+| `fix` | Bug fixes |
+| `feat` | New features |
+| `docs` | Documentation |
+| `test` | Tests |
+| `refactor` | Code restructuring (no behavior change) |
+| `chore` | Build, CI, dependency updates |
 
-Scopes: `cli`, `gateway`, `tools`, `skills`, `agent`, etc.
+Scopes: `cli`, `gateway`, `tools`, `skills`, `agent`, `install`, `whatsapp`, `security`, etc.
 
-### Security Considerations
+Examples:
+```
+fix(cli): prevent crash in save_config_value when model is a string
+feat(gateway): add WhatsApp multi-user session isolation
+fix(security): prevent shell injection in sudo password piping
+test(tools): add unit tests for file_operations
+```
 
-When contributing tools that interact with external resources:
-
-- **Skills Guard**: External skills pass through security scanning (`tools/skills_guard.py`)
-- **Dangerous Commands**: Terminal commands are checked against patterns (`tools/approval.py`)
-- **Memory Scanning**: Memory entries are scanned for injection attempts
-- **Context Scanning**: AGENTS.md and similar files are scanned before prompt injection
-
-If your change affects security, please note this in your PR.

Subject: [PATCH 44/63] fix(security): patch path traversal, size bypass, and
 prompt injection in document processing

- Sanitize filenames in cache_document_from_bytes to prevent path traversal (strip directory components, null bytes, resolve check)
- Reject documents with None file_size instead of silently allowing download
- Cap text file injection at 100 KB to prevent oversized prompt payloads
- Sanitize display_name in run.py context notes to block prompt injection via filenames
- Add 35 unit tests covering document cache utilities and Telegram document handling

Subject: [PATCH 45/63] fix(agent): handle 413 payload-too-large via
 compression instead of aborting
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 413 "Request Entity Too Large" error from the LLM API was caught by the
generic 4xx handler which aborts immediately. This is wrong for 413 — it's a
payload-size issue that can be resolved by compressing conversation history.

- Intercept 413 before the generic 4xx block and route to _compress_context
- Exclude 413 from generic is_client_error detection
- Add 'request entity too large' to context-length phrases as safety net
- Add tests for 413 compression behavior

Subject: [PATCH 52/63] Fix memory tool entry parsing when content contains
 section sign
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Use ENTRY_DELIMITER (\\n§\\n) instead of '§' when splitting entries in _read_file
- Prevents incorrect parsing when memory entries contain '§' character
- Aligns read logic with write logic for consistency
