What it does
Email Voice Profile is an agent skill from yc-software/qm. Build (or refresh) a voice profile of how the user writes email, from their own sent Gmail. The profile is what email-draft-in-voice consumes to ghostwrite email that sounds like them.
Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/fetch_sent.py`).
It sits in Writing & Content, covering Brand voice and tone, Email writing and Email management. It works with Gmail. The repository describes itself as: Multiplayer agent harness for work. The licence is MIT.
When your agent uses it
- Tasks that involve Brand voice and tone
- Tasks that involve Email writing
- Tasks that involve Email management
Example prompts
- “/email-voice-profile”
Requirements
- Python 3
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit daeb2de. 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
Ships 1 file in scripts/ (Python), which the agent can run.
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
Email Voice Profile loads about 856 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 496 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); the scripts in this folder are not scanned.

- email-voice-profile
- description
- Build (or refresh) a voice profile of how the user writes email, from their own sent Gmail. The profile is what email-draft-in-voice consumes to ghostwrite email that sounds like them.
Email voice profile
Use this when the user asks you to learn how they write email — "learn my voice",
"build my email voice profile", "study my sent mail so you can draft for me" — or when
email-draft-in-voice needs a profile that doesn't exist yet.
Personal DMs only. Sent mail is private; refuse to run this from a channel or group and offer to continue in the user's DM. The profile you produce lives in their personal workspace, so only their own conversations can read it.
1. Pull the corpus
Use the selected email access skill to retrieve up to 300 of the user's sent messages.
Strip quoted replies and ---delimited signatures, drop automated and trivial messages,
and write one JSON line per email to voice/corpus/corpus.jsonl, tagged internal or
external by recipient domain. Record corpus stats; if fewer than ~50 usable emails
survive, tell the user the profile will be rough and ask whether to continue.
2. Study it
Read a deliberate spread, not just the top of the file: oldest and newest, internal and external, one-liners and long emails. You are looking for what is distinctive — patterns a generic professional emailer would not share.
Watch for a signature block: only ---delimited signatures are stripped, so a plain
signature (name / title / phone) survives at the end of many bodies. Treat a verbatim
recurring trailing block as the mail client's signature, not a chosen sign-off — note
it in the profile so drafts never include it (Gmail appends it on send).
Show full SKILL.md (248 more words)Show less
3. Write the profile
Write voice/email-voice-profile.md in the workspace with exactly these sections,
every claim backed by observed frequency ("uses 'Best,' in 80% of external mail"),
with 2–3 verbatim example lines each:
- Register map — how tone shifts by audience (internal vs external, familiar vs cold), and how their length tracks the situation.
- Openers & sign-offs — actual greetings and closings with rough frequencies, including when they use none.
- Rhythm — sentence length, paragraph shape, how they open and end a body, use of fragments, lists, links.
- Vocabulary & phrases — recurring words, pet phrases, how they hedge, how they say yes and no.
- Punctuation & formatting quirks — dashes, ellipses, casing, emoji, bolding.
- Hard rules — things true of nearly every email ("never opens with 'I hope this finds you well'", "always lowercase to teammates").
- Anti-patterns — what they never do, plus the generic-AI tells to avoid (enthusiastic adjectives, "I'd be happy to", bullet-point answers to plain questions).
4. Validate before declaring done
Hold out 3 real threads the profile wasn't built from. For each, draft the user's
reply using only the profile, then compare with what they actually sent. Where the
real email diverges, tighten the profile — usually a missing hard rule or register
distinction. Record validated: <date> at the top of the profile once the drafts read
as plausibly theirs.
Show the user the finished profile and ask what feels wrong; their corrections go in as hard rules. Re-run this skill any time they want it refreshed — it overwrites the corpus and profile in place.
