slacrawl is a skill for Claude Code, Codex from moltis-org/moltis. It costs 41 tokens per session (957 once invoked), scanned A, original, MIT.

A tool for copying Slack, a workplace chat service, into a local database so its messages, threads, and channels can be searched offline.

In plain words
What is it for?
Syncing Slack through its API, importing Slack export ZIP files or local desktop data, searching archived conversations, and running database queries.
Why use it?
It gives you a searchable local archive instead of relying only on Slack’s interface or network access.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
    Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
  • medium Rogue Agent · line 34
    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

slacrawl 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 8d 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.

The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.

slacrawl — Slack Workspace Archive

slacrawl mirrors Slack workspace data into a local SQLite database for offline search, custom SQL queries, and inspection. Also ingests macOS Slack Desktop local data and Slack export ZIP files.

Secret Safety (MANDATORY)

  • Never read, print, or send Slack tokens to LLM context.
  • Never ask the user to paste tokens into chat.
  • The user must set tokens in their environment or Moltis credential store manually.
  • To verify credentials, only use: slacrawl doctor.

One-Time User Setup (user runs these outside the agent)

  1. Create a Slack app at https://api.slack.com/apps
  2. Add bot token scopes: channels:history, channels:read, groups:history, groups:read, im:history, im:read, mpim:history, mpim:read, users:read
  3. Install the app to your workspace and copy the Bot User OAuth Token
  4. Set tokens:
    • SLACK_BOT_TOKEN — required for standard sync
    • SLACK_APP_TOKEN — optional, for Socket Mode live tailing
    • SLACK_USER_TOKEN — optional, for fuller thread/DM coverage
  5. Verify: slacrawl doctor

Tokens can be set via environment variables or Moltis credential store (web UI → Settings → Environment Variables).

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.
