assist-review

assist-review is a skill for Claude Code, Codex from drafthq/draft. It costs 67 tokens per session (781 once invoked), scanned A, original, MIT.

A review-assistance skill for examining another engineer’s pull request before approval. A pull request is a proposed set of code changes for others to inspect and merge.

In plain words
What is it for?
Use it to prepare a handoff or sign-off review, summarize intended behavior, separate trivial edits from schema, concurrency, authentication, or API changes, and highlight risks for a human reviewer.
Why use it?
It focuses human attention on important structural changes instead of making the reviewer sift through every minor edit. It compares the changes with the original specification and design 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

assist-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.

Draft Assist Review: Human-in-the-Loop Gateway

Help human reviewers effectively review an executed track without shifting the entire cognitive burden onto them.

Red Flags - STOP if you're

  • Conducting standard unit tests; use /draft:review for that.
  • Fixing code rather than explaining logic and risk profiles to the human.
  • Reviewing output without first summarizing the source spec.md intent.

Workflow Constraints

  1. Context Extraction:

    • Load the track's spec.md and plan.md.
    • Load the track's hld.md and lld.md if present — extract Key Design Decisions, Alternatives Considered, and (LLD) class invariants and error policies.
    • Re-summarize the Intent of what this track was supposed to achieve in exactly two sentences.
  2. Blast Radius Isolation:

    • Scan the git diff generated by the target track.
    • Separate trivial edits (naming, routing adjustments, formatting) from Structural Edits (schema updates, concurrency alterations, middleware auth changes, API surface changes).
    • Present structural edits first — these are where review time should be spent.
  3. Generate the Human Helper Guide:

    • Instead of a traditional bug hunt, generate an executive summary containing a Risk Assessment.
    • For each structural edit, cite the originating decision: "I chose [Pattern] for [File/Function] because hld.md §Key Design Decisions / Alternatives Considered selected it over [rejected alternative]. You should specifically scrutinize lines X–Y because they touch [global state / auth boundary / shared schema]." Fall back to architecture.md only when no HLD exists.
    • Highlight any code that violates an LLD §Classes and Interfaces invariant (thread safety, idempotency, ordering) or contradicts an HLD §Checklist claim (e.g., "code introduces a new shared mutex but HLD declared single-writer").
    • Highlight any code that touches shared state, auth boundaries, data persistence, or concurrency.
  4. Knowledge Base Verification:

    • Verify if any pattern implemented violates the draft/guardrails.md learned anti-patterns.
    • Verify the diff is consistent with hld.md/lld.md commitments. If the diff makes structural changes not reflected in HLD §Detailed Design or LLD §Classes/Interfaces: flag for the reviewer that HLD/LLD must be amended (/draft:change) before merge.
    • If so, specifically direct the human reviewer to veto the change unless an ADR is created via /draft:adr.

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.

assist-review is a skill published in the GitHub repository drafthq/draft (40 stars, last pushed 16d ago), licensed MIT. It adds 67 tokens to every session and 781 once invoked, about $0.0003 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.
