review-r is a skill for Claude Code from pedrohcgs/claude-code-my-workflow. It costs 102 tokens per session (387 once invoked), scanned A, original, MIT.

A read-only review process for R scripts, where R is a programming language commonly used for statistics and data analysis. It checks code quality, reproducibility, statistical correctness, and common R practices, then produces a report without changing the files.

In plain words
What is it for?
Use it to audit one R script, a lecture's scripts, or all matching analysis files, with findings grouped by severity.

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-r 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 6d 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.

What it actually says

Review R Scripts

Run the comprehensive R code review protocol.

Steps

  1. Identify scripts to review:

    • If $ARGUMENTS is a specific .R filename: review that file only
    • If $ARGUMENTS is LectureN: review all R scripts matching that lecture
    • If $ARGUMENTS is all: review all R scripts in scripts/R/ and Figures/*/
  2. For each script, launch the r-reviewer agent with instructions to:

    • Follow the full protocol in the agent instructions
    • Read .claude/rules/r-code-conventions.md for current standards
    • Save report to quality_reports/[script_name]_r_review.md
  3. After all reviews complete, present a summary:

    • Total issues found per script
    • Breakdown by severity (Critical / High / Medium / Low)
    • Top 3 most critical issues
  4. IMPORTANT: Do NOT edit any R source files. Only produce reports. Fixes are applied after user review.

Changes

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.
