At a glance

A skill your agent uses when writing, fixing, editing, or reviewing Python comments and docstrings.

  • Reviewing Python comments and docstrings
  • SKILL.md covers C1: No Inappropriate Information, C2: Delete Obsolete Comments, C3: No Redundant Comments and C4: Write Comments Well, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Code quality

What it does

Clean Comments is an agent skill from ertugrul-dmr/clean-code-skills. Use when writing, fixing, editing, or reviewing Python comments and docstrings. Enforces Clean Code principles—no metadata, no redundancy, no commented-out code.

Its SKILL.md is about 420 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 quality and Technical documentation. It works with Python. The licence is MIT.

When your agent uses it

  • Reviewing Python comments and docstrings
  • Tasks that involve Code quality
  • Tasks that involve Technical documentation

Example prompts

  • “/clean-comments”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 1b6b3cc. 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 (its code samples are python).

    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

Clean Comments loads about 422 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 132 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~422

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.

Clean Comments

C1: No Inappropriate Information

Comments shouldn't hold metadata. Use Git for author names, change history, ticket numbers, and dates. Comments are for technical notes about code only.

C2: Delete Obsolete Comments

If a comment describes code that no longer exists or works differently, delete it immediately. Stale comments become "floating islands of irrelevance and misdirection."

C3: No Redundant Comments

python
# Bad - the code already says this
i += 1  # increment i
user.save()  # save the user

# Good - explains WHY, not WHAT
i += 1  # compensate for zero-indexing in display

C4: Write Comments Well

If a comment is worth writing, write it well:

  • Choose words carefully
  • Use correct grammar
  • Don't ramble or state the obvious
  • Be brief

C5: Never Commit Commented-Out Code

python
# DELETE THIS - it's an abomination
# def old_calculate_tax(income):
#     return income * 0.15

Who knows how old it is? Who knows if it's meaningful? Delete it. Git remembers everything.

The Goal

The best comment is the code itself. If you need a comment to explain what code does, refactor first, comment last.
