What it does
Comment Cleanup is an agent skill from OpenCyphal/pycyphal. Prune nonessential comments and docstrings across a codebase. Use when asked to remove verbose or redundant comments, tighten documentation, or make comment style uniform. Aggressive downsizing, but retain high-value information.
Its SKILL.md is about 650 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. It works with Python and Linux. The repository describes itself as: Python implementation of the Cyphal protocol stack. The licence is MIT.
When your agent uses it
- Asked to remove verbose
- Redundant comments
- Tighten documentation
- Make comment style uniform
Example prompts
- “/comment-cleanup”
What it can do on your machine
Read from SKILL.md and the folder at commit 34530f6. 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
Comment Cleanup loads about 654 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 349 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.

- description
- Prune nonessential comments and docstrings across a codebase. Use when asked to remove verbose or redundant comments, tighten documentation, or make comment style uniform. Aggressive downsizing, but retain high-value information.
Comment cleanup
Trim ALL comments/docstrings EXCEPT those that carry information a competent reader could not reconstruct from names, signatures, and code in a few seconds.
Keep vs. remove
REMOVE: name-echo describers, control flow / type / structure narration, section-divider banners, value-trace and "what the next line does" comments, type-obvious prose.
KEEP: design rationale (the WHY), gotchas and edge-cases, contracts and invariants, cross-references, standards or paper citations, hardware and timing facts, and the provenance of a regression test.
When uncertain whether something is rationale or restatement, keep it. The expensive mistake is erasing valuable information, not leaving one extra obvious line.
Never touch
Functional comments are not prose: type-checker and linter directives, formatter on/off switches, coverage pragmas, shebangs, and encoding lines. Preserve every one. Never delete a docstring that is a block's only body — it breaks syntax; reduce it to a terse line or a bare ellipsis instead.
Prove you changed nothing but comments
This safety net is what lets you cut confidently. Parse each file before and after, strip the docstrings from both, and compare the syntax trees: equality proves only comments and docstrings changed, since comments never appear in the tree. Treat an empty body, a bare ellipsis, and a lone pass as equivalent, so converting a sole-body docstring passes. Run it after auto-formatting. The type checker is the separate guard that no functional directive was lost.
Scale with subagents, then audit
Partition by file ownership so agents never share a file, and never let an agent run a history-rewriting or revert command — it destroys a sibling's concurrent work; undo mistakes by hand-editing. Keep the verification script out of their writable set; they only run it. Fresh subagents apply a given policy more willingly than ones asked to reverse an earlier, more conservative instruction.
When the cutting is done, audit every deletion once more for erased rationale and restore the genuine losses. Run review agents to cross-check the results. Then format, type-check, and run the full test suite before committing. A differential fuzzer or a simulation pass, if the project has one, is strong independent proof that behavior is unchanged.
