The file
We split this skill into the rules it gives an agent
8 rules. About 0 are common, 3 are distinctive, and 5 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈3
Distinctive · estimate
This author's own choices. Worth a look.
5
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 6
Write it so it sounds like {{OWNER_NAME}}, not like an assistant.
- Very specific: line 10
Read brain/identity/voice.md.
- Very specific: line 11
Read brain/writing/snippets.md for signature and boilerplate.
- Very specific: line 12
If it's to a known person, read their file in brain/people/ — context is what makes a letter land.
- Distinctive: line 19
Ask in one message, not one at a time:
- Distinctive: line 25
If the brain already answers one of these, don't ask it.
- Distinctive: line 29
Follow the template's own "Rules" section — those exist for a reason.
- Very specific: line 30
Never invent facts: no amounts, no dates, no events, no family news.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Write it so it sounds like {{OWNER_NAME}}, not like an assistant.
Before writing — always
- Read
brain/identity/voice.md. This governs everything below it. - Read
brain/writing/snippets.mdfor signature and boilerplate. - If it's to a known person, read their file in
brain/people/— context is what makes a letter land. - Pick a template from
brain/writing/letters/orbrain/writing/emails/. If none fits, write from scratch and follow the same discipline.
Ask only what you can't infer
Ask in one message, not one at a time:
- Who is it to, and what's your relationship?
- What's the one outcome you want from it?
- Any facts, dates, or reference numbers that must appear?
- Anything that must not be mentioned?
If the brain already answers one of these, don't ask it.
Draft
- Follow the template's own "Rules" section — those exist for a reason.
- Never invent facts: no amounts, no dates, no events, no family news. If a slot has no
supplied fact, leave it as
<…>and list what's missing under the draft. - Match the language the relationship is actually conducted in — if letters home are in another language or a mix, write it that way.
- Formal letters: subject line carries the reference number, one ask, a date, a contact.
Present
Show the full draft, then:
Missing: <the facts you need to fill the brackets>
Tone check: <what you aimed for> — say if you want it warmer / blunter / shorter.Rules
- Never send. Draft only. If {{OWNER_NAME}} wants it sent, create an email draft and say it's waiting — sending needs an explicit yes on the final text.
- Offer a second version at a different register if the right tone is genuinely unclear.
- Once approved, save it to
brain/writing/letters/sent/oremails/sent/with the date and recipient in the filename. These become voice samples.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
