A setup and access-control command for connecting a bot to Slack, a workplace messaging service. It saves Slack tokens and reports who is allowed to contact the assistant.

Use it to save bot and app tokens, check their status, review access rules, approve pairings, and enable an allowlist of permitted senders.

It removes the manual work of locating configuration files and checking whether the Slack connection is ready or restricted.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00056	$0.00767
Opus 5.5	$0.00022	$0.00307
Sonnet 5.5	$0.00011	$0.00153
Haiku 4.5	$0.00006	$0.00077

Measured 2mo ago against content hash 81703e4a1c7c, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade B, and why

configure scanned grade B 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/slack-bridge:configure — Slack Channel Setup

Writes the bot and app tokens to ~/.claude/channels/slack/.env and orients the user on access policy. The server reads this file at boot.

Arguments passed: $ARGUMENTS

Dispatch on arguments

No args — status and guidance

Read both state files and give the user a complete picture:

Tokens — check ~/.claude/channels/slack/.env for SLACK_BOT_TOKEN and SLACK_APP_TOKEN. Show set/not-set; if set, show first 10 chars masked.
Access — read ~/.claude/channels/slack/access.json (missing = defaults). Show: dmPolicy, allowed senders count and list, pending pairings.
What next — concrete next step:
- No tokens → show the Slack App setup guide below
- Tokens set, nobody allowed → "DM your bot on Slack. Approve with /slack-bridge:access pair <code>."
- Tokens set, someone allowed → "Ready. DM your bot to reach the assistant."

Push toward lockdown. Once the allowlist is set, offer to flip to allowlist policy.

`<bot-token> <app-token>` — save tokens

Split $ARGUMENTS — first is SLACK_BOT_TOKEN, second is SLACK_APP_TOKEN.
Warn if prefixes don't match xoxb- / xapp-.
mkdir -p ~/.claude/channels/slack
Read existing .env, update/add both lines, preserve other keys. Write back.
chmod 600 ~/.claude/channels/slack/.env
Show no-args status after saving.
Note: restart required for token changes (/reload-plugins).

`clear` — remove tokens

Delete both token lines (or the file if that's all it contains).

Slack App Setup Guide

Show this when tokens are not set:

To create a Slack bot:

1. Go to https://api.slack.com/apps → "Create New App" → "From scratch"

2. Left sidebar → "Socket Mode" → Enable Socket Mode
   Generate an App-Level Token with scope: connections:write
   Copy it — this is your SLACK_APP_TOKEN (starts with xapp-)

3. Left sidebar → "OAuth & Permissions" → "Bot Token Scopes" → Add:
     chat:write, reactions:write, im:history, im:write,
     channels:history, groups:history, files:read, files:write, users:read

4. Left sidebar → "Event Subscriptions" → Enable Events → Subscribe to:
     message.im, message.channels, message.groups, app_mention

5. Left sidebar → "Install App" → "Install to Workspace" → Allow
   Copy the Bot User OAuth Token — this is your SLACK_BOT_TOKEN (starts with xoxb-)

6. Run: /slack-bridge:configure xoxb-... xapp-...

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.
