What it does

Comment Cleanup is an agent skill from haacked/dotfiles. Delete and tighten code comments in source files after they are written. Drops narration, restatement, and change-log comments, cuts the survivors to their essential facts, and rewrites the grammar of what remains. Use when the user says the comments are too wordy, asks to clean up or trim comments, or right after generating code that came out over-commented. Not for PR descriptions, review comments, or other prose; use plain-writing for those.

Its SKILL.md is about 2.4k 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 Technical documentation, Pull requests and Text to speech and voice. It works with Git. The repository describes itself as: My dotfiles and scripts I use on dev machines.

When your agent uses it

  • The user says the comments are too wordy
  • Asks to clean up
  • Right after generating code that came out over-commented

Example prompts

  • “/comment-cleanup”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Collect the comments
  2. Leave these alone
  3. Hold doc comments to their own standard
  4. Decide each inline comment
  5. Rewrite grammar in what survives
  6. Apply and report

What it can do on your machine

Read from SKILL.md and the folder at commit 23ffed9. 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

    Shell commands in SKILL.md call:

    • git
    • bash

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    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

Comment Cleanup loads about 2.4k tokens when it runs. Until then it costs about 116 tokens; SKILL.md has 1,468 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~116
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,468 words (~2,409 tokens).

“Authoring-time rules do not hold on their own; a model that just worked out a mechanism reliably over-explains it. This is the pass that runs afterward, over comments that already exist.”
