03-assert

name	03-assert
description	Assert features work as intended - general assertions, architecture conformance, and frontend UI validation.
model	sonnet

Skill: assert

Validates correctness of implementations through iterative assertion loops, architecture checks, and browser-based frontend verification.

Available actions

#	Action	When to use
01	assert	Iterate until a feature works by running the project's coding assertions
02	assert-architecture	Verify the codebase conforms to documented architecture (C4, ADRs, tree)
03	assert-frontend	Iterate until a frontend feature works by inspecting the running UI

Routing (run first)

These actions are complementary facets, not mutually exclusive. This skill is run-one-OR-run-all:

• The user named a facet ("assert the frontend", "check architecture conformance") -> run that ONE action.
• The user asked for an unscoped assertion ("assert this works", "make the feature pass") -> ask ONE question: "Assert everything applicable, or a specific facet (coding / architecture / frontend)?" Then run all applicable, or the chosen one.
• Never silently default to action 01. Never run a blind all without offering the choice first.

When running all applicable: 01-assert is the baseline (project coding assertions); add 03-assert-frontend when the feature has a UI and a running frontend URL; add 02-assert-architecture when architecture conformance is in scope. A facet whose precondition is absent (e.g. no running URL) is skipped with a noted reason, never forced. Run the selected actions in order (01, then 03, then 02). Read and follow each selected action file.
