# Slack skill

> Current release: **[v1.91.0](../../../../docs/changes/2026-10-23-v1.91.0.md)**. Dated records below retain their original evidence dates.


> **HEADLESS IS FORBIDDEN. VISIBLE FOREGROUND EXECUTION ONLY.** Every command, automated test, diagnostic, script, build, agent and browser must run in a visible foreground window on Angela's real desktop. Use forked CMD/PowerShell windows, `execute_forked_window: true`, and `headless: false`. Monitor live; if visibility cannot be confirmed, do not run. Read the [mandatory execution policy](../../../../TestsVisiblesAndVisibleExecutionFromClaude2Codex.md).

Use the Slack Web API. `SLACK_BOT_TOKEN` must be in env.

## Endpoints

- `post`         → `chat.postMessage`
- `reply`        → `chat.postMessage` with `thread_ts`
- `read-history` → `conversations.history`
- `react`        → `reactions.add`
- `upload`       → `files.upload` (or `files.uploadV2` for >5MB)

Endpoints are at `https://slack.com/api/<method>`. Token goes in
`Authorization: Bearer ...`. Body is `application/json` for most modern
methods.
