slack-intelligence

slack-intelligence is a skill for Claude Code, Codex from tallclub/matimo. It costs 33 tokens per session (590 once invoked), scanned A, original, MIT.

A guide for reading Slack channel history and turning meaningful messages into a structured report. It sorts information into blockers, decisions, action items, and FYIs, while keeping the speaker and approximate time.

In plain words
What is it for?
Use it to summarize team discussions, identify work that is stuck, record decisions, list assigned tasks, and collect announcements.
Why use it?
It reduces the need to read long message threads to find what matters. It also combines repeated discussions and skips low-value messages such as greetings and emoji-only replies.

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-intelligence 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 5d 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.

Slack Intelligence Skill

Extract meaningful signal from raw Slack message history and produce structured, actionable reports.

Core Categories to Extract

🔴 Blockers

Messages indicating something is stuck, broken, or preventing progress. Signals: "blocked", "can't", "waiting on", "broken", "issue", "problem", "stuck", "need help", "urgent"

✅ Decisions Made

Messages where a conclusion, agreement, or direction was settled. Signals: "we decided", "going with", "confirmed", "agreed", "approved", "final", "will do", "let's go with"

📋 Action Items

Messages assigning tasks or committing to next steps. Signals: "@mention + verb", "will", "I'll", "you should", "please", "need to", "by [date/time]", "take care of"

📢 FYIs / Announcements

Informational messages with no required action. Signals: "FYI", "heads up", "just so you know", "for your awareness", "update:", "reminder"

Extraction Rules

  1. Preserve context: Always include who said what (username) and approximate time.
  2. Don't over-extract: Only pull genuinely meaningful messages. Skip greetings, reactions, emoji-only messages.
  3. De-duplicate: If the same topic appears multiple times, consolidate into one item.
  4. Mark urgency: Flag items that are time-sensitive (mention of deadlines, "today", "ASAP", "urgent").
  5. Thread awareness: A thread reply often resolves the parent message — note if resolved.

Report Format

## 📊 Channel Intelligence Report
**Channel:** #channel-name  
**Period:** Last N hours  
**Messages Analyzed:** X

---
### 🔴 Blockers (N)
- [URGENT?] @user: <summary> — <timestamp>

### ✅ Decisions Made (N)
- <decision summary> — agreed by @user1, @user2

### 📋 Action Items (N)
- [ ] @assignee: <task> — due <deadline or "unspecified">

### 📢 FYIs (N)
- <summary> — from @user

**Signal Score:** X/10 (ratio of meaningful to total messages)

Quality Checklist

  • Every item has an owner or source
  • Blockers are marked urgent if time-sensitive
  • Action items have assignee and task clearly stated
  • Report is scannable in under 2 minutes
  • No hallucinated items — only what was explicitly in the messages

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.
