Description
Send rich Slack Block Kit messages — native tables, structured layouts. Use when formatting tabular data for Slack, sending Block Kit payloads, or when markd...
Usage Guidance
This skill is a simple JSON formatter for Slack Block Kit tables. Before installing/using: (1) confirm you trust the unknown publisher (homepage not provided); (2) run the included scripts locally to verify output; (3) know that to actually post messages you'll need a Slack bot token (examples use $SLACK_BOT_TOKEN) and channel/thread IDs — supply them securely and give the token the minimum scopes needed; (4) ensure your runtime has node (to run scripts), plus curl and jq if you follow the posting examples; and (5) monitor logs to avoid accidentally leaking the token in command-history or shared output.
Capability Analysis
Type: OpenClaw Skill
Name: slack-block-kit
Version: 1.0.0
The skill provides a utility script (scripts/table.mjs) to generate Slack Block Kit table JSON and instructions (SKILL.md) for the agent to post this data to the Slack API. It follows standard OpenClaw patterns for accessing credentials and interacting with legitimate Slack endpoints (slack.com) without any evidence of data exfiltration, obfuscation, or malicious intent.
Capability Assessment
Purpose & Capability
The name/description match the included code: scripts/table.mjs builds Slack Block Kit table JSON. Minor mismatch: the SKILL.md examples assume availability of node, curl, and jq and reference a Slack bot token, but the skill metadata lists no required env vars or binaries. Those runtime tools/vars are typical for usage but were not declared in requires.*.
Instruction Scope
SKILL.md limits instructions to generating table JSON and showing how to POST it to Slack. It does not instruct the agent to read arbitrary system files or exfiltrate data. It does reference the platform config location (openclaw.json) as where a Slack bot token may be stored, but it does not include commands to read that file automatically.
Install Mechanism
No install spec (instruction-only plus a small script). The included script is pure node code that formats JSON and writes to stdout; nothing is downloaded or written to disk by an installer.
Credentials
The skill appropriately requires a Slack bot token to post messages; examples use $SLACK_BOT_TOKEN, $CHANNEL_ID, and $THREAD_TS. The skill did not declare required env vars in metadata, so users should be aware they must provide these at runtime. Ensure the token used has least-privilege (chat:write or minimal scopes).
Persistence & Privilege
always is false and the skill has no install steps that change agent config. It does not request persistent presence or elevated platform privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
