verify-bridge is a skill for Claude Code from tomeraitz/claude-slack-bridge. It costs 110 tokens per session (454 once invoked), scanned A, original, MIT.

A repository check that confirms the Slack bridge is declared in `.mcp.json`, the file that lists MCP servers available to the project.

In plain words
What is it for?
Use it before `/process-setup`, `/process`, or another workflow that needs the Slack bridge.
Why use it?
It catches a missing Slack bridge before a workflow depends on it and gives the required fix. It does not check whether the bridge is running.

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

verify-bridge 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 9d 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.

What it actually says

verify-bridge — confirm the Slack bridge MCP is declared in this repo

Verify that mcp__claude-slack-bridge is installed in the current repo by reading cwd/.mcp.json. The file must exist and must contain a server entry whose key is claude-slack-bridge (the MCP tool prefix mcp__claude-slack-bridge__* is derived from this key).

import json, os
mcp_path = os.path.join(os.getcwd(), ".mcp.json")
if not os.path.exists(mcp_path):
    # hard fail — see message below
    ...
with open(mcp_path) as f:
    cfg = json.load(f)
if "claude-slack-bridge" not in (cfg.get("mcpServers") or {}):
    # hard fail — see message below
    ...

If either check fails, print this exact message and exit non-zero. Do not offer to write the entry yourself, do not continue:

mcp__claude-slack-bridge is not installed in this repo. Add a claude-slack-bridge entry under mcpServers in .mcp.json (see the project README for the exact docker-exec snippet), then re-run the calling workflow.

Do not check whether the bridge container is running — only that the repo declares the server. Runtime health is the caller's problem, not this skill's.

On success, print one short confirmation line and exit zero:

verify-bridge: ok (claude-slack-bridge declared in .mcp.json)

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.
