- Tasks that involve Markdown

- “/proofread-markdown”
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- Check line length
- Fix voice and tone

- Style headings and lists
- Use less words in sections with steps
- Format links
What it can do on your machine
Read from SKILL.md and the folder at commit cf553cb. 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
Hosts in commands or code, which the agent is likely to contact:
dart.dev
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
Proofread Markdown loads about 345 tokens when it runs, and up to ~681 if it reads all its reference files. Until then it costs about 18 tokens; SKILL.md has 161 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 161 words (~345 tokens).
“Help us transform technical text into clear, concise, and machine-readable Markdown. We follow the Google Developer Documentation Style Guide.”
