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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Data Exfiltration · line 35 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
What it costs to keep this loaded
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 5.1 | $0.00069 | $0.00651 |
| Opus 5.5 | $0.00028 | $0.00260 |
| Sonnet 5.5 | $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 1mo 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 (45 stars, last pushed 10d ago), licensed MIT. It adds 69 tokens to every session and 651 once invoked, about $0.0003 per session on Opus 5.5. 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.
