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

quality-check-command 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.

What it actually says

quality-check-command

This command performs comprehensive code quality checks. Use it before commits or when implementation is complete.

What It Does

  1. Code Quality Check: Linting and formatting validation with Biome
  2. Type Checking: TypeScript type error detection
  3. Unit Testing: Execute unit tests with Bun test runner
  4. E2E Testing: Run integration tests with Playwright (optional)

Usage

Running this command will execute the following checks sequentially:

# 1. Code quality check (linting + formatting + type checking)
bun run check

# 2. Unit tests
bun run test:unit

# 3. E2E tests (optional)
# bun run test:e2e

Note: bun run check now includes:

  • Biome linting and formatting
  • Markuplint validation
  • TypeScript type checking (tsc --noEmit)

Check Items

✅ Code Quality

  • Syntax validation with Biome
  • Code formatting verification
  • Unused import detection
  • Naming convention adherence

✅ Type Safety

  • TypeScript strict mode validation
  • Type error detection
  • Type inference verification

✅ Testing

  • Run all unit tests
  • Test coverage validation
  • E2E test execution (critical paths)

Error Resolution

Steps to resolve detected errors:

  1. Linting Errors: Try auto-fix with bun run format
  2. Type Errors: Check the location in your editor and fix type definitions
  3. Test Failures: Review test logs and fix the corresponding code
  • ✅ After feature implementation
  • ✅ Before commits
  • ✅ Before creating pull requests
  • ✅ Before deployment

This command is available in chat as /quality-check-command.

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.
