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

context-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 4d 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

AGENTS.md

Build Commands

  • npm run build - Clean and build production
  • npm run build:dev - Development build (no clean)
  • npm run dev - Watch mode for development
  • npm run test - Run all tests
  • npm run test:watch - Watch tests
  • npm run test -- src/__tests__/tools/get-context.test.ts - Run single test file
  • npm run lint - Currently no ESLint config

Code Style Guidelines

  • TypeScript with strict mode enabled
  • ES2022 target, Node16 modules
  • Use .js extensions for imports (ESM)
  • Vitest for testing with globals enabled
  • Test files in src/__tests__/ with .test.ts suffix
  • Use Zod for runtime validation
  • Error handling with try/catch, console.error for logging
  • Follow existing patterns: interfaces in types.ts, tool functions return handlers
  • Database operations use better-sqlite3 with proper cleanup in afterEach

Agent Progress Tool Usage

Workflow Pattern

  1. Search: search_logs(projectId, query) - discover previous work
  2. Context: get_context(projectId, id, includeFull=true) - understand implementation
  3. Log: log_progress(projectId, title, content, tags, agentId) - record your work

When to Use

  • Before starting: Always search to avoid duplication
  • After completing: Log significant work (features, refactoring, infrastructure, tests)
  • Don't log: Minor tweaks, temporary code, personal notes

Best Practices

  • Use repository names as projectIds (web-app, mobile-app)
  • Be specific in content: exact files, libraries, approaches
  • 3-5 relevant tags max: technology + feature + type
  • Reference related work when building on others' contributions

Commit Guidelines

  • Use conventional commits: feat:, fix:, chore:, docs:, style:, refactor:, perf:, test:
  • feat! triggers major version bump, feat: triggers minor, fix: triggers patch
  • Commits without conventional types don't trigger releases
  • All commits appear in changelog unless marked hidden in release-please config
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.
