Slack Web API

by slackapi · 3K installs

The skill

The slack web api skill helps developers find the right Slack method, read its scopes, token type and arguments from the live docs, call it safely, page with cursors and handle rate limits and errors.

Only when you ask.

The habit

Slack API calls stay correct.

↻ Runs by itselfPR changes Slack calls

How the habit works.
You don't have to.

Three questionsWhen does it start? How does it check its work? What does it remember?

01

It starts by itself

PR changes Slack calls. Runs in GitHub Actions or Claude Code routine.

  • ↻ PR changes Slack calls
  • pull_request.opened or synchronize, files calling slack.com/api

02

It checks its work

methods match live docs. If a check fails, it tells you.

  • ✓every method name appears on the live method index
  • ✓no deprecated method used without its replacement noted
  • ✓code checks the ok field of every response
  • ✓pagination uses next_cursor, not page numbers

03

It remembers

verified method log. The next run reads it first: methods already verified with their scopes and token types.

loops/slack-api-call-audit-loop/log.md

One run, step by step.
Then it stops.

Stop ruleStops after one pull request and at most 30 methods per run.

  1. 01

    List called methods

    The agent collects every family.method name the changed code calls.

  2. 02

    Check the index

    It confirms each name on the live methods.md index at docs.slack.dev.

  3. 03

    Read each contract

    For new methods it reads the method page for HTTP verb, scopes, token type, arguments and rate tier.

  4. 04

    Review error handling

    It checks that the code reads ok and error, and honors Retry-After on ratelimited.

  5. 05

    Review pagination

    Collection calls must loop on response_metadata.next_cursor until it is empty.

  6. 06

    Report and log

    Findings go into a review comment and the log; no write method is ever run without the developer saying yes.

What it may do.
Nothing more.

Safe by defaultIt writes only in its own folder and asks you before anything goes out.

Is it for you?
Use it when it fits.

Quick checkRead both lists. If the left one sounds like you, the Slack Web API skill helps.

Use it when

  • ✓ you need the Slack method for a task
  • ✓ a call fails with missing_scope
  • ✓ you must page through results

Skip it when

  • – you only build Block Kit layouts
  • – you do not use Slack

Questions

Slack Web API skill, answered.

Does the loop call Slack methods?

It only reads docs. The skill lets read-only methods run directly but asks before any method that posts, deletes or changes state.

What about Block Kit payloads?

The skill hands those to the slack:block-kit skill and treats them as opaque arguments.

How do I install the Slack Web API skill?

Copy the prompt at the top into your agent. It installs the skill from slackapi/slack-skills-plugin and sets up the habit. Or run npx skills add slackapi/slack-skills-plugin --skill slack-api.

Is the Slack Web API skill free?

Yes. It is published under MIT. Habit is free too.

Slack Web API. Now as a habit.
