feat(cursor): PostHog error → Cursor autofix automation by riderx · Pull Request #2753 · Cap-go/capgo.app

riderx · 2026-07-24T13:48:44Z

Summary (AI generated)

Adds .cursor/automations/posthog-error-autofix.md with:
- One-time setup for a Cursor Webhook automation + PostHog Error Tracking alert
- Ready-to-paste agent prompt that investigates new/reopened PostHog issues
- Hard gates so the agent only opens a draft PR for high-confidence, easy fixes

Motivation (AI generated)

Cursor has no native PostHog trigger (Sentry exists; PostHog must use webhooks). We want new production errors to spawn a cloud agent that attempts a safe autofix without burning budget on every $exception event or opening speculative PRs.

Business Impact (AI generated)

Faster triage of new console/CLI/backend errors with less human toil. Easy bugs can land as draft PRs automatically; hard bugs stay investigation-only so agent spend stays bounded.

Test Plan (AI generated)

Create Cursor Automation (Webhook) at cursor.com/automations using the prompt in .cursor/automations/posthog-error-autofix.md
Point PostHog Error Tracking → Alerting → HTTP Webhook at the automation URL (issue created/reopened only)
Run PostHog Test function and confirm an agent run appears at cursor.com/agents
Confirm easy synthetic bugs can produce a draft PR; low-confidence cases produce no PR

Manual wiring (required after merge)

This PR only versions the prompt. Activate the loop in two UIs:

Cursor → Automations → Webhook trigger → repo cap-go/capgo.app → paste Agent prompt → enable PR tool
PostHog (EU) → Error Tracking → Alerting → HTTP Webhook on issue created or reopened → Cursor webhook URL + API key

Do not use a PostHog real-time destination on every $exception.

Version-control the webhook automation prompt and setup checklist for PostHog Error Tracking → Cursor Cloud Agent → draft PR on easy fixes. Co-authored-by: Martin DONADIEU <martindonadieu@gmail.com>

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 41 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
