tiangong-lca-mcp: Instructions file for Codex

AGENTS.md

tiangong-lca-mcp AGENTS.md is an instructions file for Codex, OpenCode from linancn/tiangong-lca-mcp. It costs 2,749 tokens per session, scanned A, original, MIT.

Repository instructions for TianGong LCA, an MCP server that handles how clients connect, authenticate, and access its tools. They define which project documents to read and which parts of the system this repository owns.

In plain words
What is it for?
Use them when working on MCP transports, authentication, OAuth, tool registration, lifecycle processing, or remote-search wrappers.
Why use it?
They help an agent find the right technical guidance before changing connection, authentication, or tool-exposure code.

Instructions file for CodexOpenCode

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

This is linancn/tiangong-lca-mcp's own configuration. It tells Codex and OpenCode how to work on tiangong-lca-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 tiangong-lca-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

tiangong-lca-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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repo Contract

tiangong-lca-mcp owns TianGong LCA MCP transports and tool exposure: STDIO, authenticated Streamable HTTP, local Streamable HTTP, OAuth helpers, tool registration, and lifecycle-model preprocessing that is intentionally part of the MCP surface. Start here when the task may change how MCP clients connect or what this MCP server exposes.

Bootstrap Order

Load docs in this order:

  1. AGENTS.md
  2. .docpact/config.yaml
  3. scripts/docpact route --root . --intent <intent> when you need path-specific routing
  4. docs/agents/repo-validation.md when proof, runtime caveats, or CI behavior matters
  5. docs/agents/repo-architecture.md when transport, auth, OAuth, or tool ownership is unclear
  6. README.md, README_CN.md, DEV_EN.md, or DEV_CN.md only when user setup or maintainer runtime details are needed

Do not start by assuming that remote search behavior or product UI truth lives in this repository.

Preferred docpact commands:

  • scripts/docpact route --root . --intent transport-auth
  • scripts/docpact route --root . --intent mcp-tools
  • scripts/docpact route --root . --intent remote-search-wrappers
  • scripts/docpact route --root . --intent openlca-tidas
  • scripts/docpact route --root . --intent repo-docs

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.
