Agentic Blueprints 4

Turns a user story into browser tests: plans the scenarios, writes Playwright code, runs it against the real page, and self-heals until it passes for the right reason.

Diff-aware multi-pass reviewer: finds bugs, then a skeptic agent verifies each before reporting.

Reads a GitHub issue and loops a coder against a verifier until it produces a minimal failing test that actually reproduces the bug.

Answers questions about a codebase with citations to the exact file — and says so honestly when the answer isn't in the repo.
