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 | $0.00033 | $0.01012 |
| Opus 5 | $0.00016 | $0.00506 |
| Sonnet 5 | $0.00007 | $0.00202 |
| Haiku 4.5 | $0.00003 | $0.00101 |
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 3d 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Slack (Read-Only)
Query Slack channels, search messages, and fetch user information using the slack CLI.
Instructions
You are helping query Slack data. Auth is handled via environment variables loaded from ~/.dots/sys/env:
SLACK_XOXP_TOKEN— user token for search, history, thread, dmsSLACK_XOXB_TOKEN— bot token for channels, users
Operations
# Test authentication
slack auth-test
# Channel operations
slack channels # List all channels
slack find-channel releases # Find channel by name
# Message history
slack history C04M5PG7P7T # By channel ID
slack history releases --limit 50 # By name, limit 50
slack history releases --days 7 # Last 7 days
# Thread replies
slack thread C04M5PG7P7T 1234567890.123456
# Search messages
slack search "deployment failed" # Full search
slack search "urgent" --days 1 # Last 24 hours
slack search "from:@darren" --days 7 --full # Full message text
# User operations
slack users # List all users
slack find-user darren # Find by name
# DMs
slack dms # List DM conversations
# JSON output (for programmatic use)
slack channels --json
Common Tasks
Get recent channel history
slack history releases --days 7
Search for mentions of a topic
slack search "outage" --days 7
Find who posted about something
slack search "from:@darren deployment" --days 30
Get activity from a specific person
# First find their user ID
slack find-user "john"
# Then search their messages
slack search "from:@john" --days 7
Full-Text Search
By default, search truncates messages to 200 chars. Use --full for complete message text:
slack search "from:@aaron" --days 7 --full
Token Types & Required Scopes
| Token | Env Var | Used For |
|---|---|---|
| User (xoxp) | SLACK_XOXP_TOKEN |
search, dms, history, thread |
| Bot (xoxb) | SLACK_XOXB_TOKEN |
channels, users, find-user, find-channel |
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.
- 3d ago First seen · 125 lines · 33 tokens per session scan A 33780b898f90
slack is a skill published in the GitHub repository drn/dots (23 stars, last pushed 2d ago), licensed MIT. It adds 33 tokens to every session and 1,012 once invoked, about $0.0002 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 2026-09-03.
