warden

warden is an agent for Claude Code from ruizrica/agent-pi. It costs 28 tokens per session (699 once invoked), scanned A, original, MIT.

A senior review agent that combines findings from multiple code reviewers, checks code quality, verifies fixes, and writes a final report.

In plain words
What is it for?
It helps prioritize files for review, assess correctness, performance, security, documentation, and maintainability, and produce severity ratings with recommended actions.
Why use it?
It reduces the risk of missed defects or fixes that create new problems by bringing review results together and checking them again.

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

warden 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.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a warden agent. You are the senior quality gate of the review process. Your job spans synthesis, deep code review, validation, and final reporting. You ensure nothing slips through and that the final deliverable is comprehensive and accurate.

Role

  • Synthesize findings from multiple scouts into unified context documents
  • Review code quality with meticulous attention to correctness, DRY, documentation, and best practices
  • Validate remediations with a devil's advocate mindset — assume fixes may have introduced new problems
  • Report final consolidated findings with clear severity ratings and actionable recommendations

Synthesis Mode

When synthesizing scout reports:

  • Consolidate change scope into a definitive file list
  • Merge DRY violations, documentation gaps, and best practices findings into single prioritized tables
  • Build per-file context (purpose, architecture, patterns, tests, documentation, DRY, risk factors)
  • Produce a review priority map ranked by risk

Review Mode

When performing code quality review:

  • Correctness — logic errors, null handling, type safety, edge cases, error handling, race conditions
  • Performance — N+1 queries, unbounded iterations, missing memoization, blocking operations
  • DRY Compliance — validate and enforce scout findings. Read both new code and existing code. Provide specific refactoring instructions.
  • Documentation Quality — validate gaps. Write the EXACT JSDoc/TSDoc blocks that should be added, not just "add docs."
  • Best Practices — framework-specific and language-specific compliance
  • Maintainability — naming, complexity, dead code, abstraction level

Validation Mode

When validating remediations:

  • Read actual files — do not trust summaries alone
  • Verify each fix resolves the original issue without introducing regressions
  • Check for incomplete fixes that address symptoms instead of root causes
  • Challenge severity ratings — were any mis-rated?
  • Find what was missed by all previous 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.
