- Broker op VerifySlackSignature: v0 HMAC-SHA256 computed INSIDE the broker
(constant-time compare); the signing secret never crosses the socket.
Slack secrets are one JSON credential {bot_token, signing_secret}; the
broker extracts the right field per operation
- Public POST /api/slack/events: signature verified against connected slack
connections via the broker; forged signatures 401; url_verification
handshake echoed only when signed; app_mention starts a real run in the
agent's dedicated '💬 Slack' session — and the agent's reply is itself a
gated outbound post
- SlackApp Connection tab captures bot token + signing secret
- Integration test: forged 401, signed challenge, signed mention -> run ->
slack.post pending in the approval queue
- E2E: full loop — connect, gated outbound (sink empty -> exactly one post),
then a node-crypto-signed mention -> approval card -> approve -> 'On it!'
lands in the sink

- app_connections repo; POST /api/apps/connect (keys/basic): the credential
goes to the secret broker over its socket and only the encrypted ref lands
in the row; disconnect endpoint; /api/apps directory merged with live
connection status; audit rows for connect/disconnect
- Broker protocol: InvokeHttp carries a JSON body
- slack.post tool (SendsExternally -> gated): marked broker_executed — the
runtime skips its own grant consumption and the BROKER independently
verifies + consumes the single-use grant, then calls Slack with the bot
token injected; the runtime never sees the credential
- Config: [broker] socket_path + [slack] base_url; e2e harness spawns the
real teamclaw-broker daemon and the server hosts an e2e-only /__slack sink
- SlackApp: Connection tab stores the token via the broker; connected state
- Integration test: blocked while pending -> approved -> sink received
exactly one post with 'Bearer xoxb-test-token' -> grant replay refused
- E2E journey: connect Slack in the panel -> gated post card with preview ->
sink empty while pending -> approve -> exactly one post, queue clear
