# Slack
Operate **Slack** through your OOMOL-connected account. This skill calls the `slack` connector with the [oo CLI](https://github.com/oomol-lab/oo-cli); OOMOL injects credentials server-side, so you never handle raw tokens.
## Running an action
Assume the user has already installed the oo CLI, signed in, and connected Slack. **Do not run `oo auth login` or open the connection URL proactively — just run the action.** Fall back to [First-time setup](#first-time-setup) only when a command actually fails with an auth or connection error.
**1. Inspect the contract** to get the authoritative input/output schema before building a payload:
```bash
oo connector schema "slack" --action "<action_name>"
```
**2. Run the action** with a JSON payload that matches the input schema:
```bash
oo connector run "slack" --action "<action_name>" --data '<json>' --json
```
- `--data` takes a JSON object string or `@path/to/file.json`; omit it to send `{}`.
- The response is `{ "data": ..., "meta": { "executionId": "..." } }`; the execution id lives under `meta.executionId`.
Each action is listed below with a one-line description; actions that change state carry a `[write]` or `[destructive]` tag. Before constructing `--data`, fetch the action's live schema with `oo connector schema` to get its authoritative input fields.
### Preserve multiline message text
Slack renders real newline characters in `text`; it renders literal backslash-n
characters as `\n`. Keep one JSON-encoding boundary:
- Before serialization, message text must contain actual LF characters.
- In serialized JSON, each intended newline appears as `\n`. If it appears as
`\\n`, it has been double-escaped and Slack will display `\n`.
- When passing raw JSON to `--data`, write the JSON newline escape exactly once.
```bash
oo connector run "slack" \
--action "post_message" \
--data '{"channelId":"C123","text":"First paragraph.\n\nSecond paragraph."}' \
--json
```
If visible formatting matters, read the posted message back and confirm that
`text` contains line breaks rather than literal `\n` characters.
## Available actions
- `add_reaction` — Add an emoji reaction to a Slack message. [write]
- `conversations_members` — List one page of member user IDs for a Slack conversation.
- `delete_file` — Delete a Slack file. [destructive]
- `delete_message` — Delete a Slack message posted through this connection. [destructive]
- `download_file` — Download a Slack-hosted file into Connector file transit storage using the connected identity's access.
- `get_channel_messages` — Get recent messag_meta.json

## Description: Slack lets an agent read, create, update, and delete Slack data through an OOMOL-connected account instead of calling Slack APIs directly. This skill is ready for commercial/non-commercial use. ## Publisher: [oomol](https://clawhub.ai/user/oomol) ### License/Terms of Use: MIT-0 ## Use Case: Developers, operators, and workspace users use this skill to let an agent inspect Slack workspace data, search messages, and perform approved Slack write or delete actions through the connected OOMOL Slack account. ### Deployment Geography for Use: Global ## Known Risks and Mitigations: Risk: The security evidence reports a suspicious fallback setup path because it tells the agent to run a remote CLI installer without an integrity check or clear user approval. Mitigation: Review the OOMOL CLI installer through an official guide, prefer a package-manager or verified release path when available, and do not let the agent run the installer automatically. Risk: Slack write and destructive actions can modify or remove workspace messages, reactions, and files. Mitigation: Confirm the exact channel, message, file, target, and payload with the user before running write or destructive actions. ## Reference(s): - [ClawHub Slack skill release](https://clawhub.ai/oomol/skills/oo-slack) - [OOMOL oo CLI](https://github.com/oomol-lab/oo-cli) - [OOMOL oo CLI install guide](https://cli.oomol.com/install-guide.md) - [Slack homepage](https://slack.com) ## Skill Output: **Output Type(s):** [text, markdown, shell commands, configuration, guidance] **Output Format:** [Markdown guidance with inline shell commands and JSON payload examples] **Output Parameters:** [1D] **Other Properties Related to Output:** [Uses the oo CLI to inspect live action schemas before constructing Slack connector payloads.] ## Skill Version(s): 1.0.10 (source: release evidence and skill metadata) ## Ethical Considerations: Users should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment.
