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 | $0.00028 | $0.01041 |
| Opus 5 | $0.00014 | $0.00521 |
| Sonnet 5 | $0.00006 | $0.00208 |
| Haiku 4.5 | $0.00003 | $0.00104 |
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 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.
Harvests environment variableshighData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.
### 3. Collect Credentials How it starts
The opening of the file, as written. The whole thing — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.enabledmust be turned on inorchestrator.yaml
Slack uses Socket Mode, so no public callback URL is required.
Runtime Adaptation
claudeRead this file first, then useCLAUDE.mdor.claude/only as extra repo context.cursorFollow this file first, then apply.cursor/rules,AGENTS.md, andCLAUDE.mdif they add local policy.codexTreat this file as the operational checklist. Do not assume slash-command wrappers exist.opencodeFollow this file first, then honorAGENTS.mdand 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 : valueformatting 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.

connect-slack is a skill published in the GitHub repository matteblack9/coding-agent-fabric (2 stars, last pushed 5mo ago), licensed MIT. It adds 28 tokens to every session and 1,041 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 1 finding (harvests environment variables). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
