Engineering
An agent on every pull request, every failure, every release.
Helios agents review diffs, explain red builds, triage issues, and write the release notes. GitHub events start them the moment work happens, and each agent has a real computer to run the analysis it needs.
The tasks
Work your engineering team can hand off
Review every pull request as it opens
The agent reads the diff, checks it against your conventions, and leaves a review with concrete suggestions before a human opens the tab.
Review new pull requests against our conventions and leave inline comments.
- github·fetch the diff for PR #2841
- github·read CONTRIBUTING.md and recent reviews
- code·run analysis over the changed files
- github·post a review with 3 inline comments
Review posted on PR #2841
- Flagged an unhandled error path in `sync.ts:142`
- Suggested reusing `parseCursor` instead of a second parser
- Confirmed the migration is backward compatible
Explain a red build
When a workflow run finishes red, the agent pulls the logs, isolates the first real failure, and posts a plain-English explanation with the likely cause.
When CI fails on main, explain the failure and suggest a fix.
- github·fetch failed jobs for run 91422
- github·download the step logs
- code·isolate the first failing assertion
- slack·post the summary to #eng-alerts
CI failure explained
- `billing.spec.ts` timed out waiting on a Stripe mock
- Introduced by #2833, which changed the fixture loader
- Suggested fix: await `seedFixtures()` before the test body
Draft the incident write-up
After an incident, the agent reconstructs the timeline from the channel and the commits, and drafts a postmortem with the facts already assembled.
Draft a postmortem from the #incident channel and the deploys around it.
- slack·read #incident-2025-03-06 in full
- github·list deploys and reverts in the window
- code·build the timeline
- notion·create the postmortem draft
Postmortem drafted
- 41-minute impact window reconstructed
- Triggering deploy identified as #2833
- 5 action items pulled from the discussion
Keep an eye on CI cost and speed
A weekly agent attributes build spend to the workflows driving it, finds the jobs that got slower, and names the change that did it.
Weekly, report CI spend and the jobs that got slower.
- warpbuild·pull last week's job and spend data
- github·find the PRs that changed those workflows
- code·attribute spend and correlate slowdowns
- slack·post the report to #platform
CI spend · week of Mar 3
- $3,140 total · up 12% week over week
- `e2e` p95 rose from 8m to 19m after #2790
- One workflow doubled after a matrix change
Ship the release notes with the release
On every tag the agent walks the merged work, groups it by theme, and publishes notes to GitHub and your docs.
When a tag is created, draft release notes and publish them.
- github·compare v2.7.0...v2.8.0
- github·publish the draft release
- notion·create the changelog entry
v2.8.0 notes published
- Features — 6 entries, led by scheduled exports
- Fixes — 11 entries, grouped by area
- Breaking — 1 entry, with a migration snippet
Controls
Everyone delegates. IT stays in control.
Agents run in isolated cloud sandboxes, one per run, with no path to each other. GitHub credentials are envelope-encrypted and scoped to the repositories you choose, webhook triggers are signed with a secret you can rotate, and org roles decide who may edit a workflow that comments on your pull requests.
- SAML and OIDC SSO with SCIM provisioning
- Org roles and resource-level sharing
- Envelope-encrypted secrets, handled server-side
- SOC 2 Type II, with an isolated sandbox per agent
Use cases
Engineering tasks in detail
PR review & digest
An agent reads each diff against your conventions and leaves a real review. A second agent summarizes the week: what merged, what is waiting, and how CI is holding up.
Incident summaries
An agent reconstructs the timeline from your incident channel and the deploys around it, identifies the triggering change, and drafts the write-up with the facts already assembled.
Templates
Start from a working agent
Every template ships with the prompt, the trigger, and the integrations it needs.
Engineering
Pull request reviewer
Reviews every pull request against your conventions, leaves inline comments, and posts a weekly digest of review load and CI health.
Engineering
Release notes writer
Turns a new tag into release notes grouped by theme, publishes them on GitHub, and files a changelog entry in Notion.
Engineering
Standup without the meeting
Reads yesterday's commits, merges, and review queue, then posts a standup so nobody has to attend one.
Engineering
Incident postmortem drafter
Reconstructs the incident timeline from Slack and GitHub, names the triggering change, and drafts the write-up in Notion.
Engineering
CI cost & speed report
Attributes build spend to the workflows driving it, finds the jobs that got slower, and names the change responsible.
Guides
Get the first one running
12 min
React to GitHub events
Start an agent the moment a pull request opens, a build goes red, or a tag lands — filtered down to exactly the events you want it on.
10 min
Attach an MCP server
Bring your own tools. Point Helios at any MCP server, choose which of its tools agents may call, and they become part of the agent's reach.
10 min
Run your first agent
Describe a task in plain English, give the agent a tool to reach for, and watch it work. Ten minutes from an empty workspace to a run you can read end to end.
Give your engineering team an agent.
Describe the task in plain English, attach a trigger, and let it work while you sleep.
