Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00069 | $0.00651 |
| Opus 5 | $0.00034 | $0.00326 |
| Sonnet 5 | $0.00014 | $0.00130 |
| Haiku 4.5 | $0.00007 | $0.00065 |
Grade A, and why
slack scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Slack
Interact with Slack workspaces via the Slack Web API.
When to Use
✅ USE this skill when:
- "Send a message to #general"
- "React to that Slack message with a thumbs up"
- "Read recent messages from #engineering"
- "Pin this message in the channel"
- "Who is user U12345?"
- "List pinned items in #announcements"
When NOT to Use
❌ DON'T use this skill when:
- Discord messaging → use the Discord channel directly
- Email → use
emailskill - Real-time Slack event listening → requires a Slack app with event subscriptions
- File uploads → use Slack's files.upload API directly
Setup
- Create a Slack app at https://api.slack.com/apps
- Add Bot Token Scopes:
chat:write,channels:read,channels:history,reactions:write,reactions:read,pins:write,pins:read,users:read - Install the app to your workspace
- Copy the Bot User OAuth Token (starts with
xoxb-) - Configure in
pythonclaw.json:
"skills": {
"slack": {
"token": "xoxb-your-bot-token"
}
}
Commands
Send a message
python {skill_path}/slack_api.py send --channel "#general" --text "Hello from PythonClaw"
Read recent messages
python {skill_path}/slack_api.py read --channel "#general" --limit 10
React to a message
python {skill_path}/slack_api.py react --channel "C123" --timestamp "1712023032.1234" --emoji "white_check_mark"
Pin a message
python {skill_path}/slack_api.py pin --channel "C123" --timestamp "1712023032.1234"
Get member info
python {skill_path}/slack_api.py user --user-id "U123"
List channels
python {skill_path}/slack_api.py channels
Notes
- Channel names can be used with
#prefix or as channel IDs (C...) - Message timestamps serve as unique message IDs in Slack
- Rate limits: ~1 request/second for most methods
- Bot must be invited to channels to read/post messages

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

slack is a skill published in the GitHub repository ericwang915/PythonClaw (41 stars, last pushed 24d ago), licensed MIT. It adds 69 tokens to every session and 651 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
