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 5.1 | $0.00036 | $0.00404 |
| Opus 5 | $0.00018 | $0.00202 |
| Sonnet 5 | $0.00007 | $0.00081 |
| Haiku 4.5 | $0.00004 | $0.00040 |
Grade A, and why
slack-bot 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 9d 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.
What it actually says
Slack Bot
Team communication through Slack's API.
When to Use
- User wants to send or read Slack messages
- User needs channel monitoring or alerts
- User wants to post status updates or reports
- User asks about team conversations
Procedure
- Verify Slack token is configured
- Identify target channel or user
- Perform the messaging operation
- Confirm delivery
Operations
- Send message to channel or DM
- Read recent messages from a channel
- React to messages with emoji
- Create and manage threads
- Post formatted blocks (rich text, buttons, etc.)
- Schedule messages for later delivery
- List channels and members
Message Formatting
Use Slack's Block Kit for rich messages:
- Text sections with markdown
- Dividers and headers
- Button actions
- Code blocks
Pitfalls
- Bot must be invited to channels to read/write
- Rate limits: 1 message per second per channel
- File uploads require files:write scope
- Thread replies need the parent message timestamp
Verification
- Message appears in target channel
- Reactions are visible on the message
- Scheduled messages show in Slack's scheduled list
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.
