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 | $0.00034 | $0.00355 |
| Opus 5 | $0.00017 | $0.00178 |
| Sonnet 5 | $0.00007 | $0.00071 |
| Haiku 4.5 | $0.00003 | $0.00036 |
Grade A, and why
c-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 6d 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
What This Skill Does
Enables Claude to send messages and share files to Slack channels and users via the slack CLI tool.
Available CLI Tool: slack
Common Commands
# Send a message to a channel
slack chat send --channel "#general" --text "Hello team"
# Send a direct message to a user
slack chat send --channel "@username" --text "Hey!"
# Upload a file to a channel
slack files upload --channel "#general" --file ./report.pdf --title "Weekly Report"
# Post with markdown formatting
slack chat send --channel "#dev" --text "*Bold* and _italic_ text"
# Reply in a thread (requires thread timestamp)
slack chat send --channel "#general" --thread-ts "1234567890.123456" --text "Reply here"
# List channels
slack channels list
Usage Guidelines
- Always confirm the target channel or user before sending
- Use
#channel-namesyntax for channels and@usernamefor DMs - File uploads support PDF, images, text, and most common formats
- Keep messages concise; use threads for follow-ups
Notes
- Requires
slackCLI to be installed and authenticated (slack auth) - Bot token must have
chat:writeandfiles:writescopes - Rate limits apply — avoid bulk sending in tight loops
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.

c-slack is a skill published in the GitHub repository daxaur/openpaw (167 stars, last pushed 3mo ago), licensed MIT. It adds 34 tokens to every session and 355 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 2026-08-30.
