spec-review

spec-review is a skill for Claude Code from komluk/scaffolding. It costs 47 tokens per session (914 once invoked), scanned A, original, MIT.

A review procedure for checking completed code against OpenSpec design and task documents. OpenSpec is a way to describe planned software changes and their acceptance scenarios before implementation.

In plain words
What is it for?
Use it after implementation to verify that the specified behaviour, files, scenarios, and tests are present and correct.
Why use it?
It finds unfinished tasks, missing files, uncovered requirements, and differences between the written plan and the code.

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

spec-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 9d 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.

OpenSpec Verification

Guide for verifying that implementation matches spec artifacts.

Input Files

File Required Purpose
{specs_path}/design.md Yes Requirements and scenarios to verify
{specs_path}/tasks.md Yes Completion checklist
{specs_path}/proposal.md Optional Original intent reference

Path Enforcement: The specs_path MUST be .scaffolding/conversations/{UUID}/specs/ where {UUID} is a valid UUID (format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx). NEVER use descriptive folder names.

Three Verification Dimensions

1. Completeness

Question: Are all tasks done and all requirements covered?

Check Method Issue Level
All checkboxes marked [x] Parse tasks.md CRITICAL if incomplete
All requirements have code Search codebase for keywords CRITICAL if missing
All new files exist Verify file paths from tasks CRITICAL if missing

2. Correctness

Question: Does the code do what the spec says?

Check Method Issue Level
GIVEN/WHEN/THEN satisfied Trace scenario through code WARNING if divergent
Tests cover scenarios Match test names to scenarios WARNING if uncovered
Edge cases handled Check error paths in code WARNING if missing
Validation commands pass Run pytest / npm run validate CRITICAL if failing

3. Coherence

Question: Does the code match design decisions?

Check Method Issue Level
Design decisions followed Compare Decisions section to code WARNING if violated
Patterns consistent Check naming, structure, style SUGGESTION
No undocumented changes Diff scope vs design scope WARNING if extra
No design deviations Cross-reference architecture WARNING if different

Verification Process

  1. Load artifacts - Read design.md, tasks.md, proposal.md
  2. Check completeness - Parse checkboxes, search for requirement implementations
  3. Check correctness - Trace each scenario through code, verify test coverage
  4. Check coherence - Compare decisions to implementation, check patterns
  5. Generate report - Summarize findings with issue levels

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.
