rafter-code-review

rafter-code-review is a skill for Claude Code from Raftersecurity/rafter-cli. It costs 123 tokens per session (1,423 once invoked), scanned A, original, MIT.

A security-focused code review guide for changes that handle untrusted input, credentials, SQL, shell commands, files, networks, or other sensitive operations.

In plain words
What is it for?
Use it to review a pull request or code diff that changes authentication, secrets, data handling, dependencies, deletion, or network-facing behavior.
Why use it?
It provides questions and checks for finding security risks before a change is merged. It also helps decide when a full security review is unnecessary.

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

rafter-code-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 yesterday.

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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Rafter Code Review — Structured Security Walkthroughs

A reviewer's skill, not an audit generator. Each sub-doc is a set of questions to run against the code — what to grep for, what to trace, what to ask before you sign off. No monolithic reports.

Pair with the rafter skill (detection: rafter scan, rafter run) and rafter-secure-design (prevention: design-phase walks). This skill is the middle stage — review before merge.

When this applies (and when it doesn't)

Scoped to the security surface of the diff, not the task's label. Walk it fully when the change touches: user / untrusted input, SQL or query building, shell / exec / subprocess, auth or access control, credentials / secrets / tokens, file paths or uploads, (de)serialization, crypto, network-facing endpoints or outbound fetchers, data deletion, or dependency / manifest changes.

If none of those are present — research / experimental / exploratory / local-only / throwaway code such as training scripts, data analysis, plotting, model eval, notebooks, or pure computation over trusted local data — a quick surface check is enough; you don't need to walk the full review or pair rafter run. But the check is the surface, not the label: research code that reads a secret, shells out, hits the network, or parses untrusted bytes is back on the engage list and gets the full walk.

How to use this skill

  1. Identify the category of code in front of you (below).
  2. Read only the matching sub-doc — do not preload them all.
  3. Work through its questions against the specific files/diff. Cite file:line evidence as you go.
  4. When in doubt on a single finding, jump to docs/investigation-playbook.md for canonical follow-up questions.
  5. Finish with rafter run --mode plus on the same diff if the stakes warrant a deep automated pass.

For: login flows, session/cookie handling, form handlers, template rendering, admin panels, anything browser-facing.

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.
