review-focus-areas

review-focus-areas is a skill for Claude Code, Codex from jackfranklin/dotfiles. It costs 27 tokens per session (545 once invoked), scanned A, original, MIT.

A review guide for examining completed software changes. It focuses attention on deviations from the plan, risky code, and areas where human judgment or another review is needed.

In plain words
What is it for?
Use it after implementation to compare the code with the original requirements, inspect the change set, and prepare focused review questions.
Why use it?
It helps reviewers spend time on meaningful risks instead of checking every unimportant change equally.

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

review-focus-areas 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 9d 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.

Review Focus Areas Skill

Use this skill when you have completed an implementation and want to prepare a guided review for the user. This skill generates a structured report flagging high-value review points while filtering out menial or uncontroversial changes.

Steps

  1. Collect Context:

    • Determine the target branch (e.g. origin/main, master, or HEAD~1 if on a single-commit branch).
    • Generate the diff: git diff <target-branch>...HEAD or similar.
    • Retrieve the original implementation plan, goals, or requirements from the conversation transcript or active task context.
  2. Invoke Subagent:

    • Invoke the self subagent with the role Fresh Eyes Reviewer to analyze the changes independently.
    • Provide the subagent with the git diff and the original plan.
    • Prompt the subagent to identify:
      1. Plan Deviations / Hiccups: Where the implementation deviated from the plan, or where unexpected technical hurdles were encountered.
      2. Risky Changes: Complex logic, state management, potential concurrency/race conditions, error handling gaps, or resource lifecycle issues.
      3. Uncertainties: Areas where a second opinion or human validation is needed.
      4. Other Key Areas: Anything else that warrants close human attention.
    • Explicitly instruct the subagent to exclude menial changes (imports, formatting, simple renames, boilerplate).
  3. Format Output:

    • The subagent should structure the output as a Markdown list of focus areas.
    • For each focus area:
      • File: Path to the file, formatted as a clickable link (e.g. [filename](file:///absolute/path/to/file#L123-L145)).
      • Type: One of Deviation, Risk, Uncertainty, or Attention.
      • Explanation: Concise explanation of the change, the reasoning behind it, and why it is flagged.
      • Code Snippet: Fenced code block showing the relevant changed or added code.
  4. Write Artifact:

    • Save the formatted output to a new markdown artifact file named review_focus_areas.md in the conversation artifact directory (<appDataDir>/brain/<conversation-id>/).
    • Present a link to this artifact to the user, highlighting key open questions or decisions.

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.
