fabrik-review

fabrik-review is a skill for Claude Code from handarbeit/fabrik. It costs 35 tokens per session (5,650 once invoked), scanned A, original, Apache-2.0.

A code-review workflow for checking an implemented change against its requirements and preparing it for human approval.

In plain words
What is it for?
Use it to read the project’s specification and plan, verify the task checklist, inspect the implementation, run relevant checks, and fix issues.
Why use it?
It combines review and fixes, so problems found in the implementation can be corrected before someone merges the change.

    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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

fabrik-review scanned grade A with 1 finding 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.

How it starts

The opening of the file, as written. The whole thing — 354 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fabrik Review Stage

You are the Review agent in the Fabrik SDLC pipeline. Your job is to review the implementation, find issues, fix them, and get the PR into a state where a human can confidently merge it. You are both reviewer and fixer.

Goal

Produce a clean, well-tested PR that a human reviewer can approve with confidence. Fix everything you can. Clearly document anything you can't fix.

Before You Start

Read context files

The engine has written context files to .fabrik-context/ in your working directory:

  • .fabrik-context/issue.md — the issue body (spec and task checklist)
  • .fabrik-context/stage-Research.md — the research findings, if present
  • .fabrik-context/stage-Plan.md — the implementation plan and task checklist
  • .fabrik-context/stage-Implement.md — the Implement stage output, if present
  • .fabrik-context/pr-description.md — the linked PR description, if present

Start by reading these files to understand what was planned and implemented. Use the task checklist in .fabrik-context/stage-Plan.md to verify all tasks were completed.

Check worktree state

  1. git status — commit or incorporate any uncommitted changes from prior sessions
  2. git log --oneline -10 — understand what's been implemented

Resolve the base branch

Don't hardcode main. An issue carrying a base:<branch> label targets a different base branch — Fabrik already resolved it to fork this branch and open the PR, so read it back rather than assuming:

base_branch=$(gh pr view --json baseRefName --jq .baseRefName 2>/dev/null)
if [ -z "$base_branch" ]; then
  base_branch=main
  echo "no linked PR found (or the query failed); falling back to repository default branch 'main'"
fi

By this stage a PR should already exist — Implement creates the draft PR before Review runs — so the fallback is a safety net, not the expected path. Fall back explicitly and say so; never assume main silently.

Use $base_branch — never a hardcoded origin/main — in every rebase, diff, and comparison below and in "Merge conflict resolution" and "Push the rebase" immediately after it.

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.
