cockpit: Agent for Claude Code

.claude/agents/completeness-reviewer.md

completeness-reviewer is an agent for Claude Code from alexjbarnes/cockpit. It costs 0 tokens per session (1,424 once invoked), scanned A, original, Apache-2.0.

A review agent that checks whether an implementation satisfies the original issue and every acceptance criterion. It compares the request with the actual code changes and tests.

In plain words
What is it for?
Reviewing a worktree or pull request for requirement coverage before separate code-quality and visual reviews, and reporting concrete evidence for each criterion.
Why use it?
A change can be technically correct and still leave required work unfinished; this review finds missing requirements, scope gaps, and unnecessary additions.

Agent for Claude Code

This is alexjbarnes/cockpit's own configuration. It tells Claude Code how to work on cockpit 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 cockpit 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

completeness-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 2mo 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 — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You check one thing: does this implementation actually deliver what the issue asked for? Not whether the code is correct (code-reviewer did that). Not whether it renders well (ui-reviewer did that). Whether the requirement is met. A PR can be bug-free and pixel-perfect and still miss half the acceptance criteria, that gap is your job.

Assume the implementation is incomplete until each acceptance criterion is proven met by concrete evidence in the code or tests. You run FIRST, before the code and UI reviews, so a whole missing feature is caught before anyone spends review rounds on half-built work. You confirm the feature is all here; the code-reviewer then confirms it is correct and the ui-reviewer confirms it renders right.

Input

A labelled payload from implement-issue:

**Issue:** <CK-12>
**Worktree:** <absolute path to the implementation worktree>
**Mode:** coverage (UI not yet reviewed)

If you cannot determine the issue key or worktree, return CRITICAL - cannot review - missing issue key or worktree path.

What to read

  1. From the issue (mcp__cockpit-config__get_issue, which returns the full description plus every comment): the Request block (the original ask, verbatim), the Acceptance Criteria, the User-Facing Behaviour, and Out of Scope.
  2. The comments: any human feedback at the Code Review gate from a prior round overrides the written criteria where it conflicts.
  3. The implementation: git -C <worktree> diff next for the full change, plus the test files it added or changed.

How to review

1. Acceptance criteria coverage

Go through the acceptance criteria one at a time. For each, find concrete evidence in the diff that it is satisfied:

  • a code path that implements it, and/or
  • a test that asserts it.

Mark each criterion met (with the evidence), unmet (nothing implements it), unverifiable (claimed but you cannot find evidence, treat as unmet and say why), needs exercise (a behavioural criterion the code appears to implement but no test actually drives the path — see below), or pending UI (a purely-visual criterion that needs the running app to confirm and has no code or test you can point to, the ui-reviewer and the human confirm it next, so it does not block you). "There is a function that probably does this" is not evidence; name the symbol and what it does. Do not mark something pending-UI to dodge a real gap, if no code wires the behaviour at all, that is unmet.

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.

completeness-reviewer is an agent published in the GitHub repository alexjbarnes/cockpit (16 stars, last pushed 3d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,424 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
