Agents Guide - Personal Assistant (Meeseeks)

What this codebase is

Meeseeks is a multi-agent LLM personal assistant that decomposes user requests into atomic actions, runs them through tools, and returns a synthesized response. It ships multiple interfaces (CLI, chat UI, REST API, Home Assistant) that share the same core engine.

Core entry points

• packages/meeseeks_core/src/meeseeks_core/task_master.py: action planning + task execution loop
• packages/meeseeks_core/src/meeseeks_core/classes.py: ActionStep, TaskQueue, AbstractTool contracts
• packages/meeseeks_core/src/meeseeks_core/session_runtime.py: session lifecycle, listing, archiving, and async runs
• packages/meeseeks_core/src/meeseeks_core/session_store.py: transcript storage, tags, and archive state
• packages/meeseeks_tools/src/meeseeks_tools/: tool implementations and integration glue
• apps/meeseeks_chat/src/meeseeks_chat/chat_master.py: Streamlit UI
• apps/meeseeks_api/src/meeseeks_api/backend.py: Flask API
• apps/meeseeks_cli/src/meeseeks_cli/cli_master.py: terminal CLI
• meeseeks_ha_conversation/: Home Assistant integration

How to get context fast

1. Use the DeepWiki MCP tool on bearlike/Assistant for a fast architecture map.
2. Read README.md and component READMEs for configuration/runtime details.
3. Use rg to locate specific behavior and follow the exact file path.
4. For CI issues, use GitHub Actions logs (GH CLI or MCP GitHub tools).

MCP tools (use first for external research)

When you need external context (other repos, CI failures, specs, APIs), prefer MCP tools instead of guessing.

• DeepWiki: fast repo architecture/flow Q&A without loading large files.
• GitHub Repos: precise file/commit/issue/PR lookup, and Actions runs/logs for CI debugging.
• Internet Search (SearXNG): broad web lookup for up‑to‑date facts and references.
• Web URL Read: fetch exact page content or headings for accurate summaries.
• Context7 Docs: official library/framework docs and code examples.
• Notifications: send status updates to the human owner when needed.

Engineering principles (project-specific)

• KISS and DRY: prefer small, obvious changes; remove redundancy instead of adding layers.
• KRY: keep requirements and acceptance criteria in view; do not drift.
• Keep tool contracts stable (AbstractTool, ActionStep, TaskQueue).
• Favor composition and reuse across interfaces; avoid duplicating core logic.
• Add or improve tests for non-trivial behavior; expand coverage when touching core logic or tools.
• Use Gitmoji + Conventional Commit format (e.g., ✨ feat: add session summary pass-through).
• Do not push unless explicitly requested.
• Use .github/git-commit-instructions.md for commit + PR titles and bodies.
• Treat language models as black-box APIs with non-deterministic output; avoid anthropomorphic language and describe changes objectively (e.g., “updated prompts/instructions”).
• Keep type hints precise; avoid loosening to Any unless no accurate alternative exists.

Orchestration insights (transferable)

• Separate tool execution from user-facing response: synthesize after tool results, don't dump raw tool output.
• Keep the loop explicit: plan -> act -> observe -> decide; re-plan only when needed.
• Make tool inputs schema-aware; prefer structured arguments for MCP tools.
• Surface tool activity clearly (permissions, tool IDs, arguments) to reduce user confusion.

Testing patterns (what worked)

• Mock as little as possible; prefer real code paths with stubbed I/O boundaries.
• Cover the full orchestration loop with fake tools and fake LLM outputs.
• Ensure tests fail when tool args are malformed (schema + coercion paths).
• Avoid hidden defaults in tests that mask production behavior.

Testing & running (common paths)

• Tests live under tests/ (use pytest).
• Local dev uses uv with configs/app.json (and configs/mcp.json when using MCP).
• Core-only install: uv sync.
• Full dev install: uv sync --all-extras --all-groups.
• Run interfaces from repo root with uv run meeseeks, uv run meeseeks-api, or uv run meeseeks-chat.
• Dockerfiles live under docker/ for base, chat, and API; Compose is supported when needed.

Linting & formatting

• Primary linting uses ruff (root + subpackages). Auto-fix with .venv/bin/ruff check --fix ..
• Type checking uses mypy. Run from repo root after installing with uv.
• flake8, pylint, and autopep8 are still available as dev tools (legacy or ad‑hoc use).
• Helper targets: make lint, make lint-fix, and make typecheck.
• Pre-commit hooks are defined in .pre-commit-config.yaml (install with make precommit-install).

Expectations for agents

• Start with DeepWiki for overview, then verify details in code.
• Keep changes minimal, readable, and well‑scoped.
• Document assumptions in PRs/notes when behavior is inferred.
