What is grok-faf-mcp AGENTS.md?

Project instructions for grok-faf-mcp, a TypeScript MCP service that gives xAI Grok persistent project context. MCP is a standard for connecting AI systems to external tools and services.

Use them when developing, deploying, or maintaining grok-faf-mcp, including its Node.js, Cloudflare Workers, TypeScript, MCP, and GitHub Actions setup.

They provide the project's context, technology choices, deployment locations, compatibility details, and current version information so work follows the repository's intended design.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00713	$0.00713
Opus 5.5	$0.00285	$0.00285
Sonnet 5.5	$0.00143	$0.00143
Haiku 4.5	$0.00071	$0.00071

Security

Grade A, and why

grok-faf-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 today.

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.

Conventions

TypeScript strict mode (tsconfig.json)
Style enforced by ESLint · Prettier — obey the configs

Guardrails

Always OK: read the tree · run the tests (npm run test) · build the project · npm run lint.
Ask first: dependency installs, deletions, migrations, schema changes, publish/release.
Never: force-push · push straight to main (branch and open a PR) · commit secrets.

Definition of Done

Done when: npm run lint exits 0 · npm run test passes · changes committed with a conventional message.

When stuck

Ask a clarifying question, propose a short plan, or open a draft PR with notes — do not push large speculative changes to main.

Security & secrets

Secrets live in .env. Never read or commit them.

Commit & PR

Conventional Commits preferred (feat:, fix:, chore:, …).
Branch off main and open a PR — never commit to main directly.
If build/test scripts or layout change, refresh this file in the same PR (faf export --agents).

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.
