slack-skills-plugin is a plugin that connects coding agents to Slack through a Slack MCP server and provides Slack-focused skills for users and developers. It is used with Claude Code, Cursor, Codex, and other coding agents to work with Slack and build Slack applications. The catalogue entries are the plugin's included skills, commands, MCP server, instructions, and settings.
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 | $0.00010 | $0.00278 |
| Opus 5.5 | $0.00004 | $0.00111 |
| Sonnet 5.5 | $0.00002 | $0.00056 |
| Haiku 4.5 | $0.00001 | $0.00028 |
Grade A, and why
channel-digest 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.
This is a copy
100% identical to channel-digest — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Given the comma-separated channel names provided in $ARGUMENTS (strip leading # and whitespace from each):
-
Parse the argument into individual channel names. Strip leading
#and whitespace from each name. -
For each channel: a. Use
slack_search_channelsto find the channel ID. b. Useslack_read_channelto read recent messages (use a limit of 50 messages per channel to keep things manageable). c. Summarize the key activity in that channel: main topics, decisions, questions, and notable messages. -
Present the digest in this format:
**Channel Digest — <today's date>** **#channel-1** - Summary point 1 - Summary point 2 **#channel-2** - Summary point 1 - Summary point 2 ... -
For each channel, keep the summary to 3-5 bullet points maximum. Focus on what's actionable or noteworthy.
-
If a channel has no recent activity, note that it's been quiet and mention when the last message was posted (if visible).
-
If a channel name can't be found, let the user know and continue with the remaining channels.
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.
