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 C, and why

connect-slack scanned grade C 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 2mo 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.

Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

connect-slack

When To Use

  • The user wants to connect or repair the Slack channel
  • Slack credentials are missing, expired, or stored in the wrong place
  • channels.slack.enabled must be turned on in orchestrator.yaml

Slack uses Socket Mode, so no public callback URL is required.

Runtime Adaptation

  • claude Read this file first, then use CLAUDE.md or .claude/ only as extra repo context.
  • cursor Follow this file first, then apply .cursor/rules, AGENTS.md, and CLAUDE.md if they add local policy.
  • codex Treat this file as the operational checklist. Do not assume slash-command wrappers exist.
  • opencode Follow this file first, then honor AGENTS.md and any OpenCode-specific config already present.

Rules

  • Never overwrite an existing credentials file without explicit confirmation
  • Present auto-detected values as numbered choices whenever possible
  • Credential files use key : value formatting with spaces on both sides of the colon
  • ARCHIVE/ must stay outside git tracking
  • Ask for secrets one field at a time and mask them in summaries

Procedure

1. Environment Preflight

Connecting Slack requires the orchestrator to be installed, Python packages to be available, and a writable credential location.

1-1. Verify orchestrator.yaml

If the file is missing, stop and run the setup-orchestrator skill first.

1-2. Verify ARCHIVE_PATH

Resolve it from orchestrator.yaml:

ARCHIVE_PATH=$(python3 -c "import yaml; print(yaml.safe_load(open('orchestrator.yaml')).get('archive', 'ARCHIVE'))")

Confirm the value before writing secrets.

1-3. Verify Python packages
$PYTHON_CMD -c "import slack_bolt" 2>/dev/null
$PYTHON_CMD -c "import slack_sdk" 2>/dev/null

If either package is missing, offer:

[1] Install now
[2] Install manually and continue later
1-4. Check for existing credentials

If ARCHIVE/slack/credentials already exists, show a masked summary and ask whether to overwrite it.

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.
