aistack-review

aistack-review is a command for Claude Code from blackms/aistack. It costs 34 tokens per session (696 once invoked), scanned A, original, MIT.

A command that repeatedly reviews a code change as an adversarial critic, checking its intended behavior, correctness, security, edge cases, and design.

In plain words
What is it for?
Use it on staged changes, a branch compared with main, or a selected file or directory.
Why use it?
It looks for defects before the change ships, including failures that a normal code review may miss.

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

aistack-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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/aistack-review

Run an adversarial review loop over a change before it ships. The goal is to break the change on paper so it does not break in production. This mirrors aistack's adversarial and reviewer agents (model: opus for the critic).

$ARGUMENTS selects the review target:

  • (default / staged) — the staged diff (git diff --staged).
  • branch — the full diff of the current branch vs main (git diff main...HEAD).
  • <path> — a specific file or directory.

Loop

Round 0 — Establish the contract

Read the change and its surrounding context. State, in one or two sentences, what the change is supposed to do (its contract). If you cannot, that is the first finding: the change lacks a clear, reviewable intent.

Round 1 — Adversarial pass (critic hat)

Attack the change. For each category, list concrete findings with file:line and a short rationale. Do not pad — only real findings.

  • Correctness: off-by-one, null/undefined, error paths, race conditions, incorrect assumptions about inputs.
  • Security: injection (SQL/shell/path), unvalidated input, secrets in code, authz gaps, unsafe deserialization. Apply the OWASP Top 10 lens.
  • Edge cases: empty/huge inputs, concurrency, timeouts, partial failure, idempotency.
  • Design / maintainability: hidden coupling, leaky abstractions, duplicated logic, dead code, missing tests for the new behavior.
  • Regression risk: what existing behavior could this silently change?

Classify each finding as blocking, should-fix, or nit.

Round 2 — Steelman & verify

For each blocking/should-fix finding, try to disprove it: read the actual code path, run a targeted test or command if cheap. Drop findings that do not survive scrutiny. This prevents false-positive noise.

Round 3 — Verdict

Emit a verdict:

  • PASS — no blocking findings. List should-fix / nits as optional follow-ups.
  • CHANGES REQUESTED — one or more blocking findings. List them first, each with a concrete suggested fix.

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.
