Instructions file for CodexOpenCode

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

This is minghsuy/ctscout-mcp's own configuration. It tells Codex and OpenCode how to work on ctscout-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 ctscout-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

ctscout-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 7d 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.

ctscout-mcp — Agent Guidelines

Pre-Session Checklist

Before starting any task:

  1. Run gh pr list --repo minghsuy/ctscout-mcp --state open. For implementation work, stop if a different open PR already touches the planned target files (the files the current task would modify). When reviewing or addressing the current PR, do not treat that PR itself as a collision.
  2. Run git status --short --branch. If the tree is dirty, do not stash, clean, reset, or overwrite local files; work from an isolated worktree based on the current upstream branch.
  3. Read README.md, LIMITATIONS.md, and CHANGELOG.md for the public package contract relevant to the change.

Verification

Run all of these before pushing:

npm run build
npm run typecheck
npm run lint
npm test
npm audit --audit-level=low

Tests must not depend on a real API key or live ctscout.dev traffic. For focused iteration, use npx vitest run <path>; still run the full gate above before pushing.

Repository Boundaries

  • This package is the local stdio compatibility client. Hosted Streamable HTTP and SSE transport implementation belongs in ctscout-worker.
  • Keep stdout exclusively for MCP JSON-RPC. Send boot diagnostics and errors to stderr; never log API keys or authorization headers.
  • Require Node.js 20 or newer and keep CTSCOUT_API_KEY in the environment.
  • Never commit .env, local MCP client configuration, generated coverage, or editor/agent state.

Code Review Rules

MCP and API contracts

  • Treat tool names, descriptions, schemas, normalized responses, errors, quota behavior, and exit behavior as public contracts. Preserve compatibility and add protocol-level tests for any externally observable change.

Cross-repository parity

  • When the tool surface changes, explicitly compare it with the hosted MCP surface in ctscout-worker. Update both implementations or document and test why a transport-specific difference is intentional; do not claim automatic parity without a check.

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.
