What it does

Distill Slack Persona is an agent skill from nickwinder/synthteam. Build or refresh a distilled persona doc for a colleague from their Slack history — dump their channel messages, then run a multi-agent distillation into a structured persona file that the ask-colleague and ask-team skills consume. Use when the user wants to "dump <name's Slack", "distill <name's persona", "build a persona for <name", "add <name as a colleague", "refresh <name's persona", or otherwise create/update the source files behind ask-colleague. This is the ingestion-side skill; ask-colleague and ask-team…

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `README.md`, `package-lock.json` and `package.json`). Compatibility notes: Requires Node.js and a Slack user token (SLACKUSERTOKEN, xoxp-) with search:read, users:read, channels:history, groups:history, channels:read, groups:read…

It sits in Agent Workflows. It works with Slack. The repository describes itself as: Consult distilled personas of colleagues — build them from Slack history, get one colleague's take, or convene a deliberating panel. A plugin for Claude Code and Codex.

When your agent uses it

  • The user wants to dump <names Slack
  • Distill <names persona
  • Build a persona for <name
  • Add <name as a colleague

Example prompts

  • “dump <name”
  • “distill <name”
  • “build a persona for <name”
  • “/distill-slack-persona”

Requirements

  • Node.js
  • A credential in SLACK_USER_TOKEN
  • Compatibility (from SKILL.md): Requires Node.js and a Slack user token (SLACK_USER_TOKEN, xoxp-) with search:read, users:read, channels:history, groups:history, channels:read, groups:read scopes. Writes to ~/.synthteam/ (override with SYNTHTEAM_HOME).

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Dump their Slack messages
  2. Distill the persona
  3. Review the diff

What it can do on your machine

Read from SKILL.md and the folder at commit 7d27255. 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 2 files in scripts/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • npm
    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • SLACK_USER_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Requires Node.js and a Slack user token (SLACK_USER_TOKEN, xoxp-) with search:read, users:read, channels:history, groups:history, channels:read, groups:read scopes. Writes to ~/.synthteam/ (override with SYNTHTEAM_HOME).

    From compatibility in the SKILL.md frontmatter.

Context cost

Distill Slack Persona loads about 1.3k tokens when it runs, and up to ~4.3k if it reads all its reference files. Until then it costs about 144 tokens; SKILL.md has 593 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~144
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.3k

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.

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 593 words (~1,334 tokens).

“Turn a colleague's Slack history into a distilled persona doc — a natural-language description of what they know, what they believe, and how they decide. The persona docs produced here are the sole input to the ask-colleague and ask-team skills.”
