Repository instructions for ly-mcp, a project that connects software tools to Taiwan’s government API. They describe the project layout, API contract, supported endpoints, tests, and coding conventions.

In plain words
What is it for?
Use them when changing ly-mcp’s API requests, MCP tools, command-line commands, tests, Swagger coverage, or related agent guidance.
Why use it?
They give contributors a shared reference for keeping the implementation, tests, command-line tools, and API documentation consistent.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is narumiruna/ly-mcp's own configuration. It tells Codex and OpenCode how to work on ly-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ly-mcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ly-mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Repository Guidelines

Project Structure & Module Organization

  • src/lymcp/api.py contains request models and HTTP calls to https://ly.govapi.tw/v2.
  • src/lymcp/server.py registers FastMCP tools, prompts, and resources.
  • src/lymcp/translate.py maps internal parameter names to upstream Chinese query fields.
  • tests/test_api_mock.py and tests/test_server_mock.py are default offline tests.
  • tests/test_api.py and tests/test_server.py are live tests marked @pytest.mark.live.
  • tests/data/ stores checked-in JSON fixtures for deterministic tests.
  • docs/ contains endpoint audits and archived implementation plans.

Swagger Contract Alignment

  • Treat the repository-root swagger.yaml, refreshed from the upstream API with scripts/download-swagger.sh, as the source of truth for supported endpoints and query parameters.
  • When swagger.yaml changes, implement every documented endpoint and query parameter end to end across request models in src/lymcp/api.py, MCP tools in src/lymcp/tools/, CLI commands in src/lymcp/commands/, and agent guidance in skills/ly/SKILL.md.
  • Keep tests/test_swagger_coverage.py and the relevant API, MCP, CLI, live, README, and endpoint-audit coverage synchronized; verify contract-alignment changes with just lint, just type, and just test.

Build, Test, and Development Commands

  • uv sync installs project and development dependencies.
  • just lint runs Ruff checks.
  • just type runs ty type checking.
  • just test runs the offline pytest suite with coverage.
  • just test-live runs live tests against the Legislative Yuan API.
  • just dev starts the MCP Inspector for src/lymcp/server.py.
  • uv run lymcp runs the MCP server locally.

Coding Style & Naming Conventions

Write Python with 4-space indentation and type annotations for public or shared code. Name request classes by action and endpoint, for example ListBillRequest or GetLawVersionRequest. Keep MCP tool functions snake_case and aligned with endpoint intent, for example list_bills.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
