Workflows

Greenfield

Request → understand → inspect the chosen scaffold/repository → minimal product design → architecture → first vertical slice → behavioral verification → continue slices → integration → browser/runtime validation → security review → code review → fresh full verification.

Existing feature

Inspect repository → trace current behavior → define the smallest coherent change → identify seam and proof → implement → test → review → verify.

Bug

Reproduce → create a tight command/test/browser loop → minimize → collect evidence → rank hypotheses → test one hypothesis at a time → root cause → regression protection → minimal fix → original reproduction → relevant verification.

Performance

Measure → identify bottleneck → form hypothesis → change one thing → measure again. No speculative caching.

Supabase

Detect local evidence → inspect config/migrations/policies → state local/linked/credential unknowns → design migration/RLS change → require explicit sensitive approval for mutation → apply through the repository's actual CLI → test identities and rollback → verify.

The plugin does not automatically spawn frontend/backend/database agents. Use one primary model and isolated subagents only when independent review or context isolation is genuinely valuable.
