What it does
Comment Code is an agent skill from jd-solanki/slidev-theme-dracula. Write clear, useful in-code comments and documentation that capture what the code cannot say for itself. Use this skill whenever writing or revising comments, docstrings, interface/API documentation, function or class headers, or inline explanations — and whenever reviewing code for comment quality or being asked to "document," "add comments," "explain in comments," or improve existing comments. Apply it even when the request only mentions writing the code, since fresh code is the moment to document it well.
Its SKILL.md is about 2.7k 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. The repository describes itself as: Dracula theme for slidev 🧛.
When your agent uses it
- Revising comments
- Interface/API documentation
- Inline explanations — and whenever reviewing code for comment quality
- Being asked to document
Example prompts
- “document,”
- “add comments,”
- “explain in comments,”
- “/comment-code”
Requirements
- Python 3
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Write the comment, then apply the test: could a first-time reader produce this from the adjacent code alone? If yes, rewrite or delete.
- For declarations, add the precision the type omits (units, bounds, null meaning, ownership, invariants). Describe what it represents, not…
- For methods/classes, write the interface comment first — behavior, parameters, return, side effects, exceptions, preconditions — keeping…
- Inside long methods, label major blocks and complex loops at a higher level, and explain any non-obvious why.
- Use words different from the entity's name; reach for the level of detail above or below the code, never the same level.
- If you can't write an interface comment without describing the implementation, treat that as a design smell, not just a writing problem.
What it can do on your machine
Read from SKILL.md and the folder at commit 383e9b1. 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 c, python and java).
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 Code loads about 2.7k tokens when it runs. Until then it costs about 132 tokens; SKILL.md has 1,336 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,336 words (~2,700 tokens).
“Comments exist to capture information that was in the writer's mind but cannot be expressed in the code itself. Code states what happens mechanically; comments supply intent, contracts, rationale, units, invariants, and the higher-level picture. Good comments make a system…”
