Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is swimmwatch/cloakbrowser-mcp's own configuration. It tells Claude Code and Codex how to work on cloakbrowser-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 cloakbrowser-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

code-review-and-quality 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 10d 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.

What it actually says

Code Review And Quality

Report evidence-backed defects before summaries.

  1. Read AGENTS.md, the requested diff, affected tests and public docs, and a nearby precedent. Use CodeGraph before broad source search when indexed.
  2. Trace affected behavior across CLI options and environment parsing, generated Playwright MCP configuration, the upstream stdio child, outer stdio or Streamable HTTP transport, local tools, cleanup, and results.
  3. Check strict TypeScript and Node ESM rules, actionable errors, cancellation, process/session cleanup, temporary-file handling, log destination and redaction, and cross-platform behavior.
  4. Confirm upstream Playwright MCP tools remain unchanged and local tools remain limited to cloakbrowser_binary_info and cloakbrowser_bridge_info unless an explicit contract change says otherwise.
  5. Review unit, integration, E2E, parity, package, Docker, documentation, localization, compatibility, and release evidence only where the diff touches those boundaries.
  6. Review dependencies, lockfile changes, workflow permissions, pinned actions and images, secrets/OIDC, registry publishing, and artifact provenance when applicable.
  7. Distinguish introduced defects from unrelated findings. Do not edit files, commit, push, resolve threads, or open/update a PR without separate authorization.

Report blocking findings first with file and line, impact, evidence, and the smallest correction. Then report important findings, optional suggestions, and verification evidence or gaps. If no findings remain, say so and identify residual testing risk.

Changes

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.
