egregore: Skill for Claude Code

.claude/skills/slack-connect/SKILL.md

slack-connect is a skill for Claude Code from egregore-labs/egregore. It costs 49 tokens per session (1,584 once invoked), scanned A, original, MIT.

A setup workflow that connects one Slack channel to Egregore notifications. Slack is a team messaging service where channels organize conversations and alerts.

In plain words
What is it for?
Use it to add Slack notifications to an Egregore setup. The connection allows the app to send messages but not read them.
Why use it?
It removes the manual work of creating the workspace app, inviting its bot, and linking a channel for notifications.

Skill for Claude Code

Written for Claude Code: $ARGUMENTS substitution.

This is egregore-labs/egregore's own configuration. It tells Claude Code how to work on egregore itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything egregore configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is PLAN_JSON=$(bash bin/notify.sh plan group "Slack channel connected — this message reached you through Egregore.").

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

slack-connect scanned grade A with 1 finding 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Set up Slack as a notification channel for your Egregore.

Arguments: $ARGUMENTS (none expected)

When to invoke

Trigger phrases:

  • "set up slack", "connect slack", "slack-connect"
  • "add slack notifications", "slack channel", "notify us on slack"

Disambiguation:

  • "set up telegram" → /telegram-connect
  • "set up teams" → /teams-connect
  • "send a message to slack" → NOT this — use the separate notification consent protocol in .claude/context/notification-consent.md

What this does

Connects one Slack channel to Egregore notifications using an app the org creates in its own workspace. After this, everything that plans a group notification may also resolve Slack as a receiving channel; all resolved channels are shown before separate dispatch approval.

The privacy contract, stated plainly to the user: the install screen will say only "Send messages as @Egregore." The app cannot read messages — the manifest requests one scope, chat:write. The workspace owns the app and the token; revoking either cuts Egregore off instantly.

Works in both modes. Check which one first:

MODE=$(jq -r '.mode // "connected"' egregore.json 2>/dev/null)
  • local — the token stays in the gitignored .env on this machine and messages go straight from here to Slack. No Egregore server is in the path.
  • connected — the token is stored on the org's row so the hosted service can deliver group notifications from any member's session.

Only Step 5 differs between the modes.

Step 0: Prerequisites

  1. A Slack workspace where this person can install apps. Some workspaces require admin approval for new apps — if theirs does, the install in Step 2 turns into a request the admin must approve first.
  2. Nothing to install locally. No CLI, no cloud account.

Step 1: Create the app from the manifest (human, ~1 min)

Show the manifest:

cat slack-app/manifest.yml

(If this instance doesn't carry slack-app/, fetch it from the framework repo.)
