- SandboxManager (tc-runtime): one container per agent, provisioned
lazily on first use, reused for the manager's lifetime, replaced
transparently if dead, destroyed on shutdown
- shell.exec tool: sh -lc inside the agent's sandbox; stdout/stderr/
exit_code return to the model as the step output. No external effects
declared — the sandbox boundary (uid 10001, no caps, seccomp
allowlist, read-only rootfs, zero egress) is the §15 control here,
not an approval gate
- RuntimeConfig.sandboxes (+ with_sandboxes builder); [sandbox] config
{image, enabled}; the server connects the Docker driver at boot and
tolerates an absent engine (shell.exec reports it per-call)
- Tests with the REAL DockerDriver: a scripted run executes two
commands — output proves uid 10001 from inside, and /home/agent state
written by the first call is read by the second (same sandbox); a
deployment without a sandbox runtime records honest error steps and
the run still completes

- 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
