What it does

Write Like Me Bootstrap is an agent skill from jxnl/personal-monorepo-template. Bootstrap a durable "write like me" skill from the user's own Slack and email writing. Use during Assistant onboarding, after Slack/Gmail or email connectors are available, or when the user asks to learn their voice, infer writing style, create a personal writing persona, generate a write-like-me skill, analyze sent messages, or capture different writing postures across email and Slack.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `agents/openai.yaml`, `references/generated-skill-template.md` and `references/style-profile-template.md`).

It sits in Writing & Content, covering Brand voice and tone, Email writing and Email management. It works with Slack and Gmail.

When your agent uses it

  • Asks to learn their voice
  • Infer writing style
  • Create a personal writing persona
  • Generate a write-like-me skill

Example prompts

  • “write like me”
  • “/write-like-me-bootstrap”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Identify the user's authored messages and separate them by channel and intent.
  2. Cluster writing into postures rather than one generic voice. Useful default
  3. For each posture, infer
  4. Compare Slack and email. Preserve differences instead of flattening them.
  5. Draft the generated write-like-me skill and profile.
  6. Present a concise preview of the inferred postures and ask for approval before
  7. After approval, create or update the generated skill in this repo.

What it can do on your machine

Read from SKILL.md and the folder at commit df86376. 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

Write Like Me Bootstrap loads about 1.1k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 103 tokens; SKILL.md has 522 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~103
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.9k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 522 words (~1,114 tokens).

“Create or update a repo-local writing-style skill from the user's real authored messages. The output should help future assistants draft in the user's voice without copying raw private messages into durable files.”
