ai-diff-reviewer-generate-extension

ai-diff-reviewer-generate-extension is a skill for Claude Code, Codex from DailybotHQ/deepworkplan-skill. It costs 167 tokens per session (3,570 once invoked), scanned A, original, MIT.

A workflow that examines a codebase and creates review rules specific to its technology, structure, security risks, conventions, and past problems. It can write these rules as an extension to the default AI review or as a complete replacement prompt.

In plain words
What is it for?
Use it to set up or customize AI pull-request reviews for a repository.
Why use it?
Generic review rules may miss project-specific risks or flag code that follows valid local conventions.

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

ai-diff-reviewer-generate-extension 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 5d 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.

Expected in a hook, worth knowing in a rule or an instructions file.

The opening of the file, as written. The whole thing — 350 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AI Diff Reviewer — Generate Extension (sub-skill)

Companion to the ai-diff-reviewer skill. Where ai-diff-reviewer runs the review, this sub-skill bootstraps the configuration — turning "here's the default reviewer" into "here's a reviewer that understands OUR stack, OUR conventions, and OUR history of bugs."

Two output modes:

Mode File written When
Extension (default) .review/extension.md Almost always — the recommended path. Layers repo-specific overrides ON TOP of the battle-tested default prompt. Cheap iteration; the default keeps improving upstream.
Full replacement (advanced) .github/prompts/pr-review.md Rare — teams that want total control, or whose codebase is so idiosyncratic (proprietary DSL, unusual paradigm) that the default is more noise than signal. Requires ongoing maintenance; you lose upstream improvements to the default.

Activation

  • "Generate a .review/extension.md for this repo"
  • "Customize the code review for our project"
  • "Help me write repo-specific review rules"
  • "Set up the AI reviewer for this codebase"
  • "Tailor the reviewer to our stack"
  • "Bootstrap the extension file"

The parent ai-diff-reviewer skill also routes to this sub-skill in two situations:

  1. Explicit intent — the developer asks for setup/customization instead of running a review (any of the triggers above).
  2. Automatic bootstrap — the developer runs the review on a repo with no .review/extension.md and no .review/.skip-bootstrap marker, and answers yes at the Step 2.5 prompt in the parent skill. In this case, when this sub-skill finishes writing the file, control returns to the parent skill's Step 2 which layers the fresh extension onto the base prompt and continues the review.

Both entry paths run the same Discovery + Write flow below. Do not skip Discovery just because the invocation came from the bootstrap offer — the whole value of the extension is the file-anchored Discovery evidence, not the file itself.

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.
