From f613da4219453c58f1b2bb8b7f8fb1f9c7683a1f Mon Sep 17 00:00:00 2001 From: teknium1 Date: Tue, 17 Mar 2026 03:53:35 -0700 Subject: [PATCH 1/4] fix: add missing subprocess import in _install_neutts_deps The function uses subprocess.run() and subprocess.CalledProcessError but never imported the module. This caused a NameError crash during setup when users selected NeuTTS as their TTS provider.

Now cleanup() also runs 'docker rm -f' to fully remove the container. Also fixes pre-existing test failures in model_metadata (gpt-4.1 1M context), setup tests (TTS provider step), and adds MockInnerDocker.cleanup(). Original fix by crazywriter1. Cherry-picked and adapted for current main.

Title generation runs in a background thread so it never delays the user-facing response. Key behaviors: - Fires only on the first 1-2 exchanges (checks user message count) - Skips if a title already exists (user-set titles are never overwritten) - Uses call_llm with compression task config (cheapest/fastest model) - Truncates long messages to keep the title generation request small - Cleans up LLM output: strips quotes, 'Title:' prefixes, enforces 80 char max - Works in both CLI and gateway (Telegram/Discord/etc.) Also updates /title (no args) to show the session ID alongside the title in both CLI and gateway.

When the agent starts, it walks from cwd to the git root looking for .hermes.md (preferred) or HERMES.md, strips any YAML frontmatter, and injects the markdown body into the system prompt as project context. - Nearest-first discovery (subdirectory configs shadow parent) - Stops at git root boundary (no leaking into parent repos) - YAML frontmatter stripped (structured config deferred to Phase 2) - Same injection scanning and 20K truncation as other context files - 22 comprehensive tests Original implementation by ch3ronsa. Cherry-picked and adapted for current main.
