review

A feature-specific check that compares the implemented code with the feature plan and its supporting decisions and requirements.

In plain words
What is it for?
Use it to verify a planned feature against its contracts, phase decisions, required evidence, acceptance criteria, and recorded invariants.
Why use it?
It finds missing or conflicting implementation details that a general code review may not check because it does not use the feature's planning documents.

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

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 2d 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.

/review — Ledger vs. Implementation

Check what the code does against what the feature's documents say it does.

This is not a general code review. Bugs, security, performance and style belong to /code-review and ce:review, which are better at them and do not need the ledger. This review is the one nobody else can run, because it is the only one holding the plan, the patterns, the decisions and the evidence claims at the same time.

Arguments

  • --feature <name> — the feature directory to review against. Required; without a ledger there is nothing here to do.

What to read first

  1. 02_plan.md — schema, contracts, phase decomposition, Verification Matrix, Environment Assumptions, Invariants
  2. The core patterns doc, if the Doc Map lists one — the rules agents were told to follow
  3. decision_review.md §A and §C — the decisions that reached beyond the implementation, and whatever the user has already adjudicated
  4. Every phase file's ## Decisions — the implementation conventions that were not promoted. This is the larger set, and it binds the code just as tightly
  5. Every phase file's ## Evidence Required and ## Acceptance
  6. 05_progress_overview.md — open standing flags

Then read the code those documents describe.

What to check

Four questions, each answerable against a document rather than a judgment call:

1. Do the decisions hold in the code? Every 🟡 and ✅ entry in decision_review.md, and every row in a phase file's ## Decisions, claims something about how the system works. Check the call sites. A decision recorded once and violated in four places is the common shape, and it is commonest among the unpromoted conventions — the ledger's rows had the user's eye on them, the phase files' rows had nobody's.

2. Are the invariants implemented and re-checked? 02_plan.md names invariants with an owner phase and a re-check phase. Verify each is actually established, and actually holds at every call site — not just the one the owning phase wrote. Anything spanning phases is verified by no single phase file, which is why it survives to here.

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.

review is a command published in the GitHub repository Langerrr/zforge (10 stars, last pushed 2d ago), licensed MIT. It adds 6 tokens to every session and 1,030 once invoked, about $0.0000 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 2026-08-31.
