work-review

work-review is a skill for Claude Code, Codex from tesslio/spec-driven-development-tile. It costs 82 tokens per session (709 once invoked), scanned A, original, MIT.

A completion-checking skill that compares finished implementation work with approved specifications and their tests. A specification is a written list of the required behavior.

In plain words
What is it for?
Use it after implementation or before declaring a task complete to inspect changed files, check each requirement, verify test links, run the linked tests, and produce a pass-or-fail summary.
Why use it?
It confirms that the delivered code meets every requirement and exposes missing edge cases, absent tests, or documentation that no longer matches the implementation.

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

work-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 4d 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.

Work Review

Review completed implementation to confirm all spec requirements are satisfied and specs remain accurate.

When to use

  • After completing implementation of a spec-driven task
  • Before marking a task as done
  • When a stakeholder asks to verify completeness

Steps

  1. Find relevant specs. Identify all specs whose targets: match the files changed during implementation:

    # List changed files, then find specs targeting them
    git diff --name-only HEAD~1 | head -20
    grep -rl "targets:" specs/*.spec.md
    
  2. Check each requirement. Walk through every requirement in the spec. For each one:

    • Read the target file and confirm the requirement is implemented
    • Record the file path and line number where it's implemented (e.g., src/auth.py:42)
    • Verify edge cases called out in the spec are handled
    • For each [@test] link, confirm the test exists and exercises the requirement
  3. Run linked tests. Execute all [@test] paths and record results:

    grep -rh '\[@test\]' specs/*.spec.md | sed 's/.*\[@test\] *//' | sed 's/`$//'
    

    If any test fails, the review cannot pass — diagnose before continuing.

  4. Capture ALL discovered requirements. Compare the implementation against the spec and identify every behavioral difference — not just new features, but also:

    • Functions or events in the code that the spec doesn't mention
    • Behavior that differs from what the spec describes (e.g., silent skip vs. raising an error)
    • New error handling paths, default values, or configuration not in the spec

    For each discovered requirement:

    • Add it to the relevant spec
    • Link any tests that were created for it
  5. Update spec metadata. If implementation changed the file structure:

    • Update targets: for new, moved, or deleted files
    • Update [@test] links for restructured tests
  6. Produce review summary:

    ## Review: [Spec Name]
    
    ### Requirements
    - [x] Requirement 1 — implemented in src/foo.py:42
    - [x] Requirement 2 — implemented in src/bar.py:18
    - [ ] Requirement 3 — MISSING: no error handling for empty input
    
    ### Discovered requirements
    - Added: timeout handling for API calls (not in original spec)
    
    ### Test results
    - Linked tests: 5 passed, 0 failed
    - New tests added: tests/test_timeout.py
    
    ### Spec updates
    - Added timeout requirement to section 3
    - Updated targets to include src/baz.py

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.

work-review is a skill published in the GitHub repository tesslio/spec-driven-development-tile (53 stars, last pushed 5mo ago), licensed MIT. It adds 82 tokens to every session and 709 once invoked, about $0.0004 per session on Opus 5. 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.
