What it does
Writing Voice is an agent skill from EpicenterHQ/epicenter. Shape prose so it sounds like Braden, with conversational precision, rhythm, humor, and earned poetic turns. Use for substantial drafting or revision, an ear pass, and explicit voice or tone work in prose, UI copy, documentation, or messages. Do not use to reopen wording selected for exact use.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/spoken-destinations.md`).
The repository describes itself as: Open-source, local-first apps.

What it can do on your machine
Read from SKILL.md and the folder at commit 5b4bb69. 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 Voice loads about 1.6k tokens when it runs, and up to ~2.4k if it reads all its reference files. Until then it costs about 77 tokens; SKILL.md has 893 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 893 words (~1,569 tokens).
“Help the writing carry recognizable judgment and recognizable sound. Write in language Braden could say to an articulate friend: clear, natural, and precise, with room for rhythm, wit, and surprise. Find phrasing that makes the thought felt as well as…”
