What it does

Use when writing site copy, changelog entries, or any user-facing text. Triggered by em dash, —, copywriting, hero description, marketing site.
Its SKILL.md is about 200 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

When your agent uses it
- Writing site copy
- Changelog entries
- Any user-facing text
Example prompts
- “/no-em-dashes”
What it can do on your machine
Read from SKILL.md and the folder at commit df2dda2. 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
No Em Dashes loads about 195 tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 75 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.

No em dashes
Less —. Humans never use those.
Do not use em dashes (—) in copy, changelogs, blog posts, docs, UI strings, or chat. Use a period, comma, colon, or parentheses instead.
Hyphens in compound words are fine (per-developer, pre-revenue).
