Agent Instructions for gptme

This file provides agent-specific guidance for working on gptme. For general project information, see README.md and docs.

Git Workflow

• Never push directly to master - always use branches and PRs
• Branch naming: feat/, fix/, docs/, refactor/ prefixes
• Commit format: Use Conventional Commits
  • feat: for new features (not just docs)
  • fix: for bug fixes
  • docs: for documentation only
  • refactor:, test:, chore: as appropriate
• Stage files explicitly: Never use git add . or git commit -a
• Create PRs: Use gh pr create after pushing branch

Code Style

• Type hints: All functions must have type annotations
• Formatting: ruff format and ruff check (run via pre-commit)
• Type checking: mypy must pass
• KISS: Keep it simple - avoid over-engineering
• Small functions: Refactor deeply nested code into smaller units
• Minimal mocking: Prefer integration tests over heavy mocking

Testing

Run tests before submitting PRs:

make test           # Fast tests (excludes slow/eval)
make test SLOW=1    # Include slow tests
make typecheck      # mypy
make lint           # ruff + other checks

Project Structure

Key directories:

• gptme/ - Core library code
  • gptme/cli/ - CLI entry points
  • gptme/tools/ - Tool implementations
  • gptme/llm/ - LLM provider integrations
  • gptme/server/ - REST API server
• tests/ - Test suite
• docs/ - Sphinx documentation (RST + MD)
• scripts/ - Build and utility scripts

Core vs gptme-contrib

We aim to keep gptme core small and focused. See docs/arewetiny.rst.

Belongs in core (gptme):

• Essential tools (shell, save, patch, browser, vision)
• Core infrastructure (chat loop, message handling, LLM providers)
• Features needed by most users

Belongs in gptme-contrib:

• Specialized tools (Twitter/X, Discord, email)
• Experimental features
• Integrations with specific services
• Multi-agent patterns (consortium)

When in doubt, start in gptme-contrib. If widely adopted, consider upstreaming.

Performance

We track startup time and code size. See docs/arewetiny.rst.

CI benchmarks enforce startup thresholds.

Key Concepts

• Tool: A function the assistant can execute (shell, save, patch, etc.)
• ToolUse: Parsed representation of a tool invocation in a message
• Message: A single message in the conversation
• LogManager: Manages conversation history persistence
• Step: One LLM generation + tool execution cycle
• Turn: Complete user→assistant exchange (may include multiple steps)

See docs/glossary.md for full terminology.

Common Tasks

Adding a new tool

1. Create gptme/tools/toolname.py
2. Implement ToolSpec with execute() function
3. Tools are auto-discovered - no manual registration needed
4. Add tests in tests/test_tools_toolname.py

Running the server

uv run gptme-server --port 5000

Building docs

make docs
