implementation-review

implementation-review is a skill for Claude Code, Codex from drvoss/everything-copilot-cli. It costs 36 tokens per session (1,524 once invoked), scanned A, original, MIT.

A checklist-based review that compares a completed implementation with its original task specification, handoff, issue, or review report. It separates completed, incorrect, missing, and intentionally excluded items.

In plain words
What is it for?
Use it to inspect a commit, branch, pull request, or delegated task item by item and produce precise follow-up work.
Why use it?
It catches gaps between what was requested and what was delivered. This is different from a general code-quality review because it checks against a prior agreement.

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

implementation-review 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 today.

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.

Implementation Review

Implementation review is not ordinary code review. The goal is to verify whether the delivered change actually matches the original task spec, handoff, or review report — and to turn any gaps into a precise follow-up the implementation machine can execute.

When to Use

  • A delegated implementation task already landed and you need to check it against the original spec
  • Another machine or session reported "done" and shared a commit, branch, or PR
  • A task file contained multiple required items and you need item-by-item status
  • You want to separate approved, needs correction, missing, and validly excluded

When NOT to Use

Instead of implementation-review Use
Reviewing code quality or correctness without a prior task spec code-review
Proving that a fix works by rerunning commands verification-before-completion
Turning upstream ecosystem changes into backlog candidates ecosystem-intake
Security-specific review of a change pr-security-review or agent-owasp-check

Prerequisites

  • You have the original task spec, handoff doc, issue, or review report
  • You have the delivered commit hash, branch, PR, or diff range
  • You know the intended scope well enough to judge exclusions

Workflow

1. Gather the canonical inputs

Before reviewing the implementation, pin down:

  • the original request or task file
  • the success criteria or required items
  • the delivered commit, branch, or PR
  • any stated exclusions or tradeoffs from the implementation pass

If there is no explicit spec, stop and say the review can only assess general quality, not compliance.

2. Inspect the delivered change

Use a stable diff view rather than memory or a narrative summary:

git --no-pager show <commit-hash> --stat
git --no-pager show <commit-hash> --unified=3

# or compare a range
git --no-pager diff <base>...<head>

If the implementation arrived as a PR, review the changed files list first, then inspect the substantive diff.

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.
