server: Instructions file for Codex

AGENTS.md

server AGENTS.md is an instructions file for Codex, OpenCode from mcpambassador/server. It costs 399 tokens per session, scanned A, original, Apache-2.0.

Project-specific instructions for the mcpambassador/server codebase. They describe its documentation, review agreements, required checks, and the conditions a change must meet before it is considered complete.

In plain words
What is it for?
Use them when changing this repository to find the right project documents, obtain required reviews, update status records, and run builds, linting, type checks, formatting checks, and tests.
Why use it?
They give a coding agent the repository's local rules and prevent unfinished changes from being treated as done. The CI gate, meaning the same build and test checks used in automated integration, makes completion verifiable.

Instructions file for CodexOpenCode

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

This is mcpambassador/server's own configuration. It tells Codex and OpenCode how to work on server 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 server 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

server 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 2d 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.

Project Instructions

Current State

  • Development plan: mcpambassador_docs/dev-plan.md
  • Architecture: mcpambassador_docs/architecture.md
  • Status: mcpambassador_docs/status.md

Working Agreements

  • All code changes require Code Reviewer review before merge
  • Security Engineer signs off on auth, crypto, and external API changes
  • Database Engineer signs off on schema changes
  • Write outputs to mcpambassador_docs/ — not just chat
  • Update mcpambassador_docs/status.md after completing any task
  • Append to mcpambassador_docs/lessons-learned.md, never overwrite

Definition of Done — CI Gate (MANDATORY)

No code change is considered complete until ALL of the following pass locally:

pnpm -r build        # All 8+ packages compile
pnpm -r lint         # 0 errors (warnings OK)
pnpm format:check    # All files match Prettier style
pnpm -r typecheck    # tsc --noEmit passes in every package
pnpm -r test         # All tests pass

If any step fails, the agent MUST fix the issue before calling the task complete. These mirror the GitHub Actions CI workflow (.github/workflows/ci.yml).

Common gotchas

  • Prettier: After editing ANY .ts, .json, or .md file, run pnpm format before committing
  • ESLint: The config is eslint.config.js (ESLint 10 flat config). No .eslintrc.* files.
  • Typecheck: Each package has its own tsconfig.json extending tsconfig.base.json. Changes to shared types can break downstream packages.
  • Node version: CI runs on Node 22 (and 24). Do not use APIs added after Node 22.

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.
