A command that connects the current Claude Code session to a Slack channel, a shared chat room for a team or project.

Use it to view the current connection, find a Slack channel by name or ID, start the listening service when needed, and bind the session to that channel.

It gives the session a recorded channel connection so status updates can be posted where the team already communicates.

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	$0.00000	$0.00696
Opus 5	$0.00000	$0.00348
Sonnet 5	$0.00000	$0.00139
Haiku 4.5	$0.00000	$0.00070

Security

Grade A, and why

slack-sync 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Slack Sync

Bind this session to a Slack channel. After binding, the session registry shows this session as connected to the channel, and Claudicle can post status updates there.

Arguments

Target: $ARGUMENTS

If empty, show the current binding status and active sessions.

Instructions

If no arguments: Show Status

python3 ~/.claude/hooks/soul-registry.py list --md

Print the output and stop.

If a channel is specified:

Step 1: Resolve the Channel

If the argument starts with C and looks like a Slack channel ID (e.g., C12345), use it directly. Otherwise, treat it as a channel name (strip leading # if present) and resolve it:

source ~/.zshrc 2>/dev/null; python3 ~/.claude/skills/slack/scripts/slack_channels.py --filter "CHANNEL_NAME" --json

Parse the JSON output to find the matching channel ID and name.

Step 2: Ensure Listener Is Running

python3 ~/.claude/skills/slack/daemon/slack_listen.py --status

If not running, start it:

cd ~/.claude/skills/slack/daemon && python3 slack_listen.py --bg

Step 3: Bind in Registry

The session ID is available from the environment or hook context. Use it to bind:

python3 ~/.claude/hooks/soul-registry.py bind "SESSION_ID" "CHANNEL_ID" "#CHANNEL_NAME"

Replace SESSION_ID with the current session's UUID.

Step 4: Post Announcement

source ~/.zshrc 2>/dev/null; python3 ~/.claude/skills/slack/scripts/slack_post.py "CHANNEL_ID" "_Claudicle connected from $(basename $(pwd))_"

Step 5: Confirm

Print:

Session bound to #channel-name. This session is now visible in the soul registry as connected to that channel.

Important

The session must already be registered (happens automatically via the SessionStart hook).
Binding is per-session. When the session ends, the registry entry is cleaned up.
Multiple sessions can bind to the same channel.
To unbind, just exit the session or start a new one without /slack-sync.

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.
