DietrichGebert/ponytail
Reviews a diff only for unnecessary complexity and lists what to delete or shrink, one numbered line per finding with the location, the cut and its replacement.
Review a diff or file through the Chisle lens: flag over-engineering, speculative abstractions, reinvented stdlib, and verbose code that a lazier approach would shrink.

At a glance
Review a diff or file through the Chisle lens: flag over-engineering, speculative abstractions, reinvented stdlib, and verbose code that a lazier approach would shrink.

What it does
Chisle Review is an agent skill from JayPokale/Chisle. Review a diff or file through the Chisle lens: flag over-engineering, speculative abstractions, reinvented stdlib, and verbose code that a lazier approach would shrink. One finding per line, no praise. Use when the user says "chisle review", "review this for bloat", or invokes /chisle-review.
Its SKILL.md is about 360 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Code review and Code simplification. The repository describes itself as: Cut your AI coding agent's token bill on three axes: terse prose, YAGNI-first code, and tool-output compression. Claude Code, Pi, Cursor, Codex, Gemini + 4 more. Zero deps… The licence is MIT.
When your agent uses it
- The user says chisle review
- Review this for bloat
- Invokes /chisle-review
Example prompts
- “chisle review”
- “review this for bloat”
- “/chisle-review”
What it can do on your machine
Read from SKILL.md and the folder at commit 52c954b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Chisle Review loads about 362 tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 120 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md

- description
- Review a diff or file through the Chisle lens: flag over-engineering, speculative abstractions, reinvented stdlib, and verbose code that a lazier approach would shrink. One finding per line, no praise. Use when the user says "chisle review", "review this for bloat", or invokes /chisle-review.
Chisle review
Review the diff/file for what could be deleted or simplified, not for style nits.
What to flag
- Abstraction with one implementation (interface/factory/wrapper for a single case)
- Reinvented stdlib (hand-rolled debounce, deep-clone, groupBy, date math)
- New dependency for what a few lines or an installed dep already does
- Config/option that never varies
- Speculative "for later" scaffolding with no current caller
- Verbose code where a native platform feature (CSS, DB constraint,
<input type>) does it
What NOT to flag
- Input validation at trust boundaries
- Error handling that prevents data loss
- Security / accessibility code
- Anything the task explicitly required
Output format
One finding per line. No preamble, no praise.
path:line: <what's over-built>. <the lazier replacement>.Example:
cache.js:12: ApiCacheManager class for one call site. Replace with lru_cache / a Map.
search.js:40: hand-rolled debounce util. setTimeout+clearTimeout inline is enough.End with a one-line verdict: N findings. Est. <X> lines removable.
