ponytail-reviewer

ponytail-reviewer is an agent for Claude Code from wildcard/caro. It costs 0 tokens per session (2,610 once invoked), scanned C, original, AGPL-3.0.

A read-only code reviewer that looks for unnecessary complexity, strict rules, abstractions, dependencies, files, or process steps in a proposed change. It approaches the review from a skeptical senior-developer perspective.

In plain words
What is it for?
Use it to review code changes for over-engineering and to question whether each implementation choice is needed.
Why use it?
It helps catch solutions that solve more than the problem requires and may add maintenance work without a clear benefit.

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 C, and why

ponytail-reviewer scanned grade C 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 8d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

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.

ponytail-reviewer is an agent published in the GitHub repository wildcard/caro (37 stars, last pushed yesterday), licensed AGPL-3.0. It costs nothing until one of its globs matches a file; then it loads 2,610 tokens. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
