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 | $0.00983 | $0.00983 |
| Opus 5 | $0.00491 | $0.00491 |
| Sonnet 5 | $0.00197 | $0.00197 |
| Haiku 4.5 | $0.00098 | $0.00098 |
Grade A, and why
pagespeed-insights-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 9d 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 — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Rules — pagespeed-insights-mcp (MCP Server)
Цей файл доповнює глобальний ~/.grok/AGENTS.md. Правила з нього мають вищий пріоритет у цьому репозиторії.
Специфіка проєкту
- TypeScript + Node.js (>=20) MCP server на базі
@modelcontextprotocol/sdk+ Zod. - 17 інструментів для Google PageSpeed Insights + Chrome UX Report + Lighthouse.
- Публікація: npm + GitHub Packages (semantic-release).
- Docker + docker-compose для локального запуску.
- Тести: Vitest + nock. Лінтинг: ESLint + Prettier.
- Документація: MkDocs (docs/ + mkdocs.yml).
.serena/вже налаштовано (TypeScript + memories для conventions/tech_stack/task_completion).
Обов'язкові практики (MCP + TS)
- При додаванні/редагуванні інструментів — слідуй mcp-builder skill (research → Zod schemas + descriptions з прикладами → annotations: readOnlyHint/destructiveHint/idempotentHint → structured output де можливо).
- Кожний tool: чітке ім'я, опис, inputSchema (Zod), actionable error messages.
- Перед публікацією:
npm run lint && npm run typecheck && npm test && npm run build. - Зміни в публічному API / tool signatures — оновлюй README, TESTING.md, CHANGELOG (conventional commits).
- Локальний MCP для self-dogfooding: використовуй
npx pagespeed-insights-mcpабоnode dist/index.jsзGOOGLE_API_KEY.
Serena + .serena/
- Використовуй Serena MCP (
serena__*tools) для семантичного пошуку, рефакторингу, аналізу символів у TS коді. - Поважай
.serena/memories/*.md(conventions, tech_stack, task_completion) — вони є джерелом правди для цього проєкту. - При роботі з великими змінами — спочатку semantic_search / find_symbol, потім безпечні edits.
Професійні skills тільки
- Дозволені: mcp-builder, implement, design, review, pr-babysit, execute-plan, check, best-of-n, create-skill (та інші high-star з marketplace, які ти особисто перевірив).
- Заборонено створювати custom

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.

pagespeed-insights-mcp AGENTS.md is an instructions file published in the GitHub repository ruslanlap/pagespeed-insights-mcp (58 stars, last pushed yesterday), licensed Apache-2.0. It adds 983 tokens to every session, about $0.0049 per session on Opus 5. A static security scan graded it A with 0 findings.
