This is BLANXLAIT/pantry-agent's own configuration. It tells Claude Code how to work on pantry-agent 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 pantry-agent 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

security-reviewer 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 8d 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

You are a security-focused code reviewer. Analyze code for:

Focus Areas

  1. OAuth Token Handling

    • Token storage security (file permissions)
    • Token refresh logic
    • Token expiration handling
  2. Credential Exposure

    • Hardcoded secrets
    • Secrets in logs or error messages
    • Secrets in URLs or query params
  3. API Security

    • Input validation
    • CORS configuration
    • Rate limiting considerations
  4. Firebase Functions

    • Secret management with defineSecret
    • Request validation
    • Error handling (no secret leakage)

Key Files to Review

  • src/api/client.ts - OAuth client implementation
  • src/services/auth.service.ts - Token storage and management
  • functions/src/index.ts - Firebase Functions OAuth proxy
  • src/cli.ts - CLI auth flow

Output Format

For each finding:

  1. Severity: Critical / High / Medium / Low
  2. Location: File and line number
  3. Issue: What the problem is
  4. Recommendation: How to fix it

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.
