lighthouse-budget-author

Overview

lighthouse-perf is the runner - it takes a .lighthouserc.js and runs Lighthouse against it. This skill writes the config, picking thresholds per route at design time so the runner has something meaningful to assert against.

The two artifacts this skill produces:

1. Lighthouse CI assertion config in .lighthouserc.js - per-route LCP / INP / CLS thresholds.
2. Resource-size budget in budget.json (the Lighthouse "performance budgets" feature) - per-resource-type byte caps.

Without this skill, teams either (a) set every threshold to the "good" default and ignore route-specific reality, or (b) pick thresholds via guesswork. Either ends with a gate the team disables.
