Add Anthropic as a first-class inference provider, bypassing OpenRouter for direct API access. Uses the native Anthropic SDK with a full format adapter (same pattern as the codex_responses api_mode). ## Auth (three methods, priority order) 1. ANTHROPIC_API_KEY env var (regular API key, sk-ant-api-*) 2. ANTHROPIC_TOKEN / CLAUDE_CODE_OAUTH_TOKEN env var (setup-token, sk-ant-oat-*) 3. Auto-discovery from ~/.claude/.credentials.json (Claude Code subscription) - Reads Claude Code's OAuth credentials - Checks token expiry with 60s buffer - Setup tokens use Bearer auth + anthropic-beta: oauth-2025-04-20 header - Regular API keys use standard x-api-key header ## Changes by file ### New files - agent/anthropic_adapter.py — Client builder, message/tool/response format conversion, Claude Code credential reader, token resolver. Handles system prompt extraction, tool_use/tool_result blocks, thinking/reasoning, orphaned tool_use cleanup, cache_control. - tests/test_anthropic_adapter.py — 36 tests covering all adapter logic ### Modified files - pyproject.toml — Add anthropic>=0.39.0 dependency - hermes_cli/auth.py — Add 'anthropic' to PROVIDER_REGISTRY with three env vars, plus 'claude'/'claude-code' aliases - hermes_cli/models.py — Add model catalog, labels, aliases, provider order - hermes_cli/main.py — Add 'anthropic' to --provider CLI choices - hermes_cli/runtime_provider.py — Add Anthropic branch returning api_mode='anthropic_messages' (before generic api_key fallthrough) - hermes_cli/setup.py — Add Anthropic setup wizard with Claude Code credential auto-discovery, model selection, OpenRouter tools prompt - agent/auxiliary_client.py — Add claude-haiku-4-5 as aux model - agent/model_metadata.py — Add bare Claude model context lengths - run_agent.py — Add anthropic_messages api_mode: * Client init (Anthropic SDK instead of OpenAI) * API call dispatch (_anthropic_client.messages.create) * Response validation (content blocks) * finish_reason mapping (stop_reason -> finish_reason) * Token usage (input_tokens/output_tokens) * Response normalization (normalize_anthropic_response) * Client interrupt/rebuild * Prompt caching auto-enabled for native Anthropic - tests/test_run_agent.py — Update test_anthropic_base_url_accepted to expect native routing, add test_prompt_caching_native_anthropic |

Hermes Agent ⚕
The self-improving AI agent built by Nous Research. It's the only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who you are across sessions. Run it on a $5 VPS, a GPU cluster, or serverless infrastructure that costs nearly nothing when idle. It's not tied to your laptop — talk to it from Telegram while it works on a cloud VM.
Use any model you want — Nous Portal, OpenRouter (200+ models), z.ai/GLM, Kimi/Moonshot, MiniMax, OpenAI, or your own endpoint. Switch with hermes model — no code changes, no lock-in.
| A real terminal interface | Full TUI with multiline editing, slash-command autocomplete, conversation history, interrupt-and-redirect, and streaming tool output. |
| Lives where you do | Telegram, Discord, Slack, WhatsApp, Signal, and CLI — all from a single gateway process. Voice memo transcription, cross-platform conversation continuity. |
| A closed learning loop | Agent-curated memory with periodic nudges. Autonomous skill creation after complex tasks. Skills self-improve during use. FTS5 session search with LLM summarization for cross-session recall. Honcho dialectic user modeling. Compatible with the agentskills.io open standard. |
| Scheduled automations | Built-in cron scheduler with delivery to any platform. Daily reports, nightly backups, weekly audits — all in natural language, running unattended. |
| Delegates and parallelizes | Spawn isolated subagents for parallel workstreams. Write Python scripts that call tools via RPC, collapsing multi-step pipelines into zero-context-cost turns. |
| Runs anywhere, not just your laptop | Six terminal backends — local, Docker, SSH, Daytona, Singularity, and Modal. Daytona and Modal offer serverless persistence — your agent's environment hibernates when idle and wakes on demand, costing nearly nothing between sessions. Run it on a $5 VPS or a GPU cluster. |
| Research-ready | Batch trajectory generation, Atropos RL environments, trajectory compression for training the next generation of tool-calling models. |
