Lovable

The Fix-with-AI prompt PulseLight generates is calibrated for Lovable's chat surface — restraint-engineered so the agent stays scoped to the one fix and doesn't regenerate the project.

Lovable is a hosted AI builder. PulseLight integrates via the paste-into-chat flow — copy the prompt, paste into your Lovable project’s chat, apply the diff. There is no MCP / skill integration today (Lovable doesn’t expose one).

Paste-into-chat flow

Open the blocker on the Fix Queue.

Click the blocker, expand the card, click Fix with Lovable. PulseLight copies the Lovable-tuned prompt to your clipboard.

Open your Lovable project.

Lovable’s in-project chat panel is where the fix happens. The prompt is shaped to keep Lovable focused on the one file rather than triggering a project-wide regeneration.

Paste the prompt.

Lovable reads the affected file, proposes a change, asks before writing. The prompt’s “Do NOT” section is doing the work here — without it, Lovable tends to rewrite adjacent files for stylistic consistency.

Sync, validate, re-scan.

Lovable pushes to your connected GitHub repo on apply. PulseLight re-scans on the next push and the blocker drops off the Fix Queue.

Anatomy of a Lovable-tuned prompt

Same v2 shape as every Fix-with-AI prompt. Lovable-specific tweaks:

<!-- pulselight prompt v2 (lovable) -->

Goal:
<plain-English description>

Affected files:
- <path>:<line>

Working rules (Lovable-specific):
- Keep the change scoped to the affected file.
- Don't regenerate components for stylistic consistency.
- Match the project's existing framework conventions; don't
  introduce a new one.

Do NOT:
- Rewrite unrelated files. Lovable's instinct is to keep
  the project "consistent" — for this fix, divergence is
  fine.
- Re-style the file beyond the change scope.
- Add new dependencies unless the fix specifically needs
  one (justify in the summary).

Validation steps:
- Re-scan the project: `pulselight scan`
- Verify the affected file's behaviour in Lovable preview.

Output a summary of the change in 3 bullets and confirm the
unrelated files are untouched.

Why restraint engineering matters more here

Lovable’s strength — ship-the-whole-app speed — is the same instinct that hurts when you’re fixing a single blocker. Without explicit constraints, Lovable will reformat, re-style, and re-think adjacent files in pursuit of project cohesion. The PulseLight prompt explicitly tells Lovable that cohesion isn’t the goal here; surgical fix is.

If Lovable insists on regenerating

Sometimes Lovable proposes a sweeping change anyway. Reply in chat with: “Limit the change to the file in ‘Affected files.’ Don’t modify other files.” Then re-paste the goal. Two turns is the worst case — usually not needed.
