C Slack is an agent skill from daxaur/openpaw. Send messages and upload files to Slack channels using the slack CLI. Supports direct messages, channel posts, file uploads, and thread replies.

It sits in Backend & APIs, covering Messaging and chat bots and File uploads and storage. It works with Slack. The repository describes itself as: Personal Assistant Wizard for Claude Code — npx pawmode. The licence is MIT.
When your agent uses it
- Tasks that involve Messaging and chat bots
- Tasks that involve File uploads and storage
Example prompts
- “/c-slack”
What it can do on your machine
Read from SKILL.md and the folder at commit a2562d1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
C Slack loads about 363 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 93 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
