What it does

Slack Drafts is an agent skill from yc-software/qm. Create Slack message drafts in the user's own composer, as the user, through their per-user Slack OAuth. Drafting only — the user reviews and sends from Slack.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/slack_drafts.py`).

It sits in Backend & APIs, covering OAuth and OpenID Connect. It works with Slack. The repository describes itself as: Multiplayer agent harness for work. The licence is MIT.

When your agent uses it

  • Tasks that involve OAuth and OpenID Connect

Example prompts

  • “/slack-drafts”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 23af31b. 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.

    Shell commands in SKILL.md call:

    • python3

    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

Slack Drafts loads about 657 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 322 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~657

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.

Slack drafts

Use this skill when the user wants a Slack message prepared for them to review and send themselves: "draft a reply to X", "prep a message for #general", "write that up as a Slack draft". The draft lands in their own Slack composer, attributed to them, targeted at the conversation you choose — nothing is posted.

This is an OAuth connector. The resolved user's Slack user token lives on your computer as $VAULT_TOKEN_SLACK_COM. Do not ask the user for a token, log it, or use another principal's. If the variable is empty or Slack returns 401/403, the user either has not connected Slack or connected before this permission existed — tell them to (re)connect it through the product OAuth flow.

Use the bundled helper for every draft — it owns destination resolution, rich-text block construction, and the required draft envelope:

bash
python3 skills/slack-drafts/scripts/slack_drafts.py create --to '#general' --text 'hello'
python3 skills/slack-drafts/scripts/slack_drafts.py create --to '@jane' --text-file body.txt
python3 skills/slack-drafts/scripts/slack_drafts.py create --to C0123ABCDEF --thread-ts 1712345678.000100 --text '...'
python3 skills/slack-drafts/scripts/slack_drafts.py resolve --to '#general'
  • --to takes a channel/IM ID (C…/G…/D…), a user ID (U…/W…), #channel-name, or @name (matched against username, display name, real name, or email; ambiguous matches are refused — fall back to a user ID).
  • Text is plain; URLs become clickable links. Write it exactly as the user would send it — it goes out under their name, in their voice, once they hit send.
  • --thread-ts targets the draft at a thread reply instead of the channel composer.
  • Drafts are create-only through this API: you cannot list, edit, or delete a draft once made. To revise, tell the user to discard the old draft in Slack and create a fresh one. Never work around this by posting messages — drafting means the user sends.
  • Opening a brand-new DM needs the im:write scope; tokens connected before that scope existed can only draft into conversations that already exist. On a missing_scope error, tell the user to reconnect Slack.
  • Slack keeps at most one draft per composer: a second draft into the same channel or thread fails with attached_draft_exists. Tell the user to send or discard the existing draft, then retry.
