arbiterx-review

arbiterx-review is a skill for Claude Code from NeelPrime/arbiterx. It costs 17 tokens per session (246 once invoked), scanned A, original, Apache-2.0.

A code-review skill that checks changes against ten engineering rules, including avoiding unnecessary work, handling errors, using types, cleaning up resources, and addressing security risks.

In plain words
What is it for?
Use it to review a diff or selected files, receive exact line-based findings, get minimal fix suggestions, and obtain an overall quality score with a pass or fail result.
Why use it?
It turns broad code-quality expectations into a structured review with concrete findings. It also identifies issues such as dead code, inefficient loops, late validation, and hardcoded secrets.

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

arbiterx-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 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.

What it actually says

ArbiterX Review

Review the current diff (or specified files) against the 10 engineering rules.

Instructions

  1. Look at the git diff or specified files

  2. Check each one against:

    • YAGNI: Is there anything built that wasn't asked for?
    • Error handling: Are all I/O operations protected?
    • Type safety: Are all functions typed?
    • Resource cleanup: Are all resources properly closed?
    • Magic numbers: Are there inline numeric literals?
    • Dead code: Unused imports, commented code?
    • Single responsibility: Functions over 30 lines?
    • Fail fast: Late validation?
    • Performance: O(n²) patterns, string concat in loops?
    • Security: Hardcoded secrets, SQL injection, eval?
  3. Output a table:

File Issue ArbiterX Severity Fix
  1. Give an overall score (0-100) and pass/fail (threshold: 70)

Be specific. Point to exact lines. Suggest the minimal fix.

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.
