Connect external events to local coding agents through ClawTab. Create an API token, test delivery, and trigger CI triage from GitHub Actions with duplicate protection.
Introduction
A CI run fails while your coding agent is idle. An external event can start the investigation: GitHub Actions sends an authenticated request to ClawTab, and ClawTab launches an agent on your selected machine.
This guide covers the token, target machine, test request, and GitHub workflow. The copyable workflow asks for read-only triage. Then we look at the extra controls in our bmux automatic-repair setup.
You need a paired, online ClawTab machine with a local checkout and a working agent login. The examples use Codex. Reading private CI logs also requires GitHub access on that machine; the GitHub runner's credentials are not transferred to the agent.
An external event becomes an agent request
The diagram shows the path: an event source calls an adapter, the adapter sends a Bearer-authenticated POST to ClawTab, and the relay routes it to your machine. Your checkout and tools stay on that machine.
For GitHub CI, the adapter can be a GitHub Actions workflow. You do not need to add a repository webhook pointing directly at ClawTab. A raw GitHub webhook has a different payload and signature scheme from the trigger API. For another service, use an HTTP step in n8n or a small handler that validates the incoming event and builds the ClawTab request. GitHub documents how to validate its webhook signatures.
Conceptual request flow. GitHub Actions is the adapter in this guide; this is a diagram, not a trace of a completed repair.
Create a token for this integration
Open ClawTab Remote, then Settings → API tokens → + New token. Give it a recognizable name, such as ci-triage, and copy it into your automation service's secret storage.
The real settings capture above shows our bmux-ci-repair token. Its prefix was hidden for this article. A separate token makes the integration easy to identify and revoke; its name does not restrict which repository or machine it can access.
For the workflow below, add CLAWTAB_CI_REPAIR_TOKEN as a GitHub Actions repository secret. Add CLAWTAB_CI_REPAIR_DEVICE_ID and CLAWTAB_CI_REPAIR_WORK_DIR as repository variables. The first is your machine's UUID; the second is an absolute path on that machine, such as /Users/you/workspace/project.
Check the target under Settings → Manage machines. For an already paired host, the command below reads only its saved device ID from the default configuration file. Do not copy the whole settings file into a workflow: it also contains credentials. An empty result means you should check pairing and the host configuration before proceeding.
sed -n 's/^ device_id: *//p' "$HOME/.config/clawtab/settings.yaml"
Test delivery before connecting real events
The API tokens screen includes a request example, shown below. The test here adds an explicit machine ID and asks for a small JSON result without changing the repository. Run it in Bash with jq installed, replacing the machine UUID and working directory.
It waits for up to 30 seconds. A coding agent can take longer to start, so keep the returned trigger ID if the wait expires. Check the new session in ClawTab for login, trust, or permission prompts before sending another request.
# Read the token without putting its value in shell history (Bash).
read -rsp 'ClawTab API token: ' CLAWTAB_TOKEN; echo
export CLAWTAB_TOKEN
export CLAWTAB_DEVICE_ID='replace-with-your-machine-uuid'
export CLAWTAB_WORK_DIR='/absolute/path/to/your/repository'
jq -n '{
device_id: env.CLAWTAB_DEVICE_ID,
agent: {
provider: "codex",
work_dir: env.CLAWTAB_WORK_DIR,
prompt: "Delivery test. Do not edit repository files, commit, or push. Write {\"status\":\"ok\"} as JSON to the file named by CLAWTAB_RESULT_FILE, then finish."
},

ClawTab Remote, October 16, 2026. The built-in example shows the endpoint and agent payload. The guide adds explicit routing and a JSON result test.
Check the result separately from dispatch
A dispatched status means the request reached the machine. It does not mean the agent finished. On our first delivery test, ClawTab opened a Codex session, but the agent paused for permission to write its result file. That is a working delivery path with an unresolved execution step.
The agent should write valid JSON to the path in CLAWTAB_RESULT_FILE. Poll the returned poll_url with the same Bearer token. For a successful JSON test, inspect status, result_status, and result. A result you can parse is stronger evidence than an opened terminal.
Response
What to do
dispatched
Open the session or poll for completion.
succeeded
Inspect the result and verify the requested work.
Wait timeout
Poll the same trigger; the agent may still be running.
no_device
Check the machine UUID, account, and connection. Do not assume automatic redelivery.
result_status: missing or invalid_json
Inspect the agent's result-file step.
For long tasks, send wait: false and poll later. A request timeout is not evidence that the agent was cancelled. Repeating an identical request with the same idempotency_key returns the existing trigger; changing the payload while reusing the key is rejected.

Start CI triage from GitHub Actions
Save the following as .github/workflows/clawtab-ci-triage.yml on your default branch. Change Check to your CI workflow's name and change main throughout if your default branch differs. Configure the secret and two variables described above first.
GitHub's workflow_run event starts this workflow after CI completes. The conditions accept failed or timed-out push runs from the same repository. The script skips obsolete commits, uses a stable key per repository and commit, and sends an asynchronous triage request. It checks dispatch status; it does not wait for the diagnosis.
The workflow executes no checkout or downloaded artifact from the failing run. On the target machine, the agent must already have permission to read logs through gh. Its local approval settings still apply. Confirm that it can finish the delivery test before relying on unattended runs.

What changes when the agent can repair CI?
Read-only triage gives you a diagnosis to review. Repair automation also needs authority to edit, test, commit, and possibly push. Our bmux setup makes those permissions explicit and adds controls around the trigger. These are integration rules, rather than guarantees provided by every ClawTab request.
Control in the bmux setup
Reason
Only selected workflows and current main-branch push failures
Avoid unrelated events and obsolete failures.
One idempotency key per failing commit
Several failing workflows should start one repair.
A wrapper-enforced repository lock and a separate Git worktree
Avoid overlapping repairs and preserve active checkouts.
Required checks before merge or push
A plausible patch is not a verified fix.
A repair marker in the final commit
If that repair fails CI, stop for human investigation.
No force-push, test disabling, or permission changes
Keep the repair within the task's intended scope.
The dispatch checks are enforced by the workflow and script, and a local wrapper enforces the repository lock. Worktree use, verification, and commit rules are also instructions to the agent; review its output and the resulting CI. A prompt alone is not an access-control boundary.
We resolved the initial approval pause by switching the repair integration to a saved tmux job, bmux/ci-repair. Its wrapper uses a dedicated approval configuration, collects the agent's structured final response, and writes the ClawTab result itself. Normal interactive sessions keep their existing settings. This separates the repair runner's configuration from a one-off agent prompt.
The request below is specific to that installed job. Replace the machine UUID and commit SHA; it will not work until the corresponding local job and runner exist. The bmux setup notes link the wrapper, dispatch script, and job configuration.
We verified eight checks, a successful local-agent smoke test, and a passing GitHub dry run. That dry run checks event eligibility without launching a repair; the separate smoke test checks local execution and result delivery.
We then tested the full path with a temporary workflow that deliberately fails. Its repair dispatch succeeded, an agent started locally, and it pushed commit 74a91cc deleting the fixture. The screenshot shows that cleanup on main. Deleting this synthetic workflow was the explicitly authorized test task; it is not permission to remove real failing tests.
This demonstrates event delivery, local execution, verification, and a pushed change for a controlled task. The cleanup passed nine guard tests and workflow lint. Other CI runs were still in progress when we recorded the result, so this is not a claim that all project CI passed or that arbitrary failures can be repaired.
Real end-to-end hook test, October 16, 2026: the local repair agent pushed deletion of the temporary fixture. The crop shows the commit and part of its diff; it does not show all project CI passing.
Connect other services using the same request shape
In n8n, use an HTTP Request node with method POST, the trigger endpoint, a Bearer credential, and a JSON body containing device_id plus either agent or job. Store the token in the tool's credential store. Use an event ID as the idempotency key when each event should run once.
For a saved job, send job and string-valued params instead of agent. This keeps a reusable task definition on the target machine. Our browser-trigger guide uses that pattern for a local browser job.
For raw incoming webhooks, validate the sender first, allow only the event types you intend to handle, and map selected fields into the task. Keep issue text, CI logs, and other event content separate from the instructions that authorize the agent's actions.
An offline machine can return no_device with a retry_at hint. The current endpoint does not automatically redeliver that trigger. Replaying its idempotency key returns the same record. Bring the machine online, inspect the original attempt, and decide whether to start a new request with a new key.
We also hit a Cloudflare block when testing with Python's default User-Agent. An application User-Agent got that request through. If you see a non-JSON HTTP 403, inspect the edge response before debugging the agent payload. That observation is specific to our test, not a promise that changing a header resolves every access error.
Disable the GitHub workflow to pause new CI requests. Revoke its token in ClawTab and remove the repository secret to remove that integration's access. Neither action stops an already running agent; inspect and stop that session separately when needed.
The useful first milestone is small: one external event, one request, one agent, and one checked result. Once that path works, add the specific permissions and verification your repair workflow needs. Use ClawTab Remote to inspect progress and answer prompts away from the host.
Frequently Asked Questions
Use an adapter that validates and translates the event. A raw GitHub webhook does not have the Bearer authentication or agent/job body required by the ClawTab trigger API. For CI, a workflow_run GitHub Actions workflow can be that adapter.
No. It means the request reached the machine. Poll the trigger and inspect the agent session and structured result. The agent may still be starting or waiting for approval.
Do not rely on that. The current endpoint can return a terminal no_device result with a retry hint. It does not automatically redeliver that request, and the same idempotency key returns the existing record.
Yes. Send either an agent object with a prompt and working directory or a job name with parameters. Treat the token as an execution credential; a descriptive token name is not a repository restriction.
No. Revocation prevents later authenticated requests using that token. Stop an already running session separately.
