What it does
Writing User Facing Copy is an agent skill from PostHog/posthog, published by the product's own GitHub organization. Sets the voice and word choices for any text a person reads in PostHog: UI labels, buttons, tooltips, empty and error states, notifications, in-app messages, onboarding, docs, and support replies. Use ALWAYS before writing or editing user-facing copy, and whenever a code change adds or changes a string a user will see. Enforces a humane, neutral tone: no editorializing, no sales-y or edgy one-liners, no em-dashes (use hyphens or rewrite), sentence case, plain language. Also carries feature-naming rules that are…
Its SKILL.md is about 1.3k 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 Commit messages, Technical documentation and Plain language and style rules. It works with PostHog. The repository describes itself as: :hedgehog: PostHog is the leading platform for building self-driving products. Our developer tools – AI observability, analytics, session replay, flags, experiments, error…

Example prompts
- “Wizard”

- “/writing-user-facing-copy”
What it can do on your machine
Read from SKILL.md and the folder at commit 812e5c6. 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
Writing User Facing Copy loads about 1.3k tokens when it runs. Until then it costs about 186 tokens; SKILL.md has 692 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 692 words (~1,307 tokens).
“This is the operational gate for anything a person reads in the product or around it. Run it before writing or editing user-facing text, and whenever a code change introduces or changes a visible string.”
