rudder: Skill for Claude Code

.agents/skills/maintainer/agent-work-reviewer-maintainer/SKILL.md

agent-work-reviewer-maintainer is a skill for Claude Code, Codex from Undertone0809/rudder. It costs 59 tokens per session (3,007 once invoked), scanned A, original, Apache-2.0.

A read-only review guide for checking whether an agent's work solved the requested problem and is ready to hand off.

In plain words
What is it for?
Use it to review code changes, user-interface workflows, proposals, agent results, tests, screenshots, and final handoffs against stated acceptance criteria.
Why use it?
It helps catch product, implementation, evidence, and handoff gaps that the person who did the work may miss.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is Undertone0809/rudder's own configuration. It tells Claude Code and Codex how to work on rudder 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 rudder 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

agent-work-reviewer-maintainer 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 13d 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 — 311 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent Work Reviewer Maintainer

Judge whether the work solved the right problem, produced a coherent Rudder experience, and earned the claimed level of acceptance. This is a read-only review role, not an implementation or black-box-verifier role.

Proportional Scope

Follow AGENTS.md section 9.1. Review the requested artifact and risks; do not turn a docs or skill review into a product-release workflow. For instructions, evaluate realistic decisions and conflicting rules. Runtime/data identity and black-box product evidence apply only to claims that depend on them.

A short requirement-to-evidence mapping is sufficient for a bounded task. Use a formal packet or state matrix when multiple requirements, corrections, workflow states, or integration risks make it useful. Do not manufacture missing packet fields for facts that cannot affect the requested outcome.

Role Boundary

  • Inspect the request, diff, relevant code, tests, screenshots, and running surface when they materially affect judgment.
  • Do not edit files, stage, commit, push, or fix findings during the review.
  • Treat inherited parent history and implementer claims as author-claimed evidence until this reviewer independently inspects or reruns them.
  • Use product-acceptance-verifier-maintainer for final black-box acceptance. Reviewer inspection can challenge or refine acceptance criteria, but cannot replace the verifier's terminal verdict when AGENTS.md requires that gate.

Verdicts

Return exactly one reviewer verdict and name its level:

  • accept: no blocking product, implementation, evidence, or handoff gap remains for this level.
  • needs more evidence: the available artifact or proof is insufficient for a trustworthy judgment.
  • reject: the work solves the wrong problem, creates a blocking regression, or requires a different product or implementation direction.

Use accept with clearly non-blocking suggestions when the task is ready. Do not emit conditional accept: it conflates a pass with an unmet condition. For older receipts, inspect the actual conditions before deciding applicability.

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.
