Conciseness

Roughly 300 of the ~470 lines are generic template artifacts (a boilerplate auth microservice, users/sessions/audit DDL, an OpenAPI login spec, a stock Kubernetes Deployment, caching/sharding YAML) that Claude can already produce unaided — heavily padded relative to the guidance actually needed. Matches anchor 2 ('noticeably verbose; several unnecessary explanations or padded sections') — not 1 because there is no prose explaining known concepts, not 3 because the volume of inline boilerplate is far beyond 'some unnecessary explanation'.

Actionability

Concrete guidance exists (the phase's five activities, named deliverables such as 'System Design Document' and 'Sequence Diagrams', and complete-looking output templates), but the operative instruction reduces to 'design architectures' with no executable workflow for producing those deliverables. It also cannot score 4 because the example code blocks are corrupted — 'application$json', 'apps$v1', 'POST $auth$login', 'https:/$api.example.com$v1', '1000$sec' use '$' where '/' belongs, so none of the OpenAPI, k8s, or SQL examples are copy-paste usable. Not 2 because the templates and deliverables list do give real, specific shape to the output.

Workflow Clarity

A sequence is present — the Architecture phase 'transforms algorithms into system designs' via steps 1–5 (components → interfaces → technology → scalability → deployment) with a deliverables list — but the checkpoints are entirely implicit: there is no guidance on consuming the pseudocode retrieved by the pre-hook, no validation of the produced design, and no handoff step (e.g., what the post-hook's memory_store of 'arch_complete' should contain). Matches anchor 3 ('steps listed but validation gaps; sequence present but checkpoints missing or implicit').

Progressive Disclosure

The body has good section structure (numbered 'High-Level Architecture' through 'Scalability Design', plus 'Architecture Deliverables' and 'Best Practices'), but it is a monolith: the SQL DDL, OpenAPI spec, and Kubernetes manifests are exactly the content that belongs in references/ files, and no references/ directory or signaled external files exist at all. Matches anchor 3 ('some structure... content that should be separate is inline') — not 2 because headers and organization are clear, not 4 because nothing is split out or navigable via references.

Specificity

The description 'Agent skill for architecture - invoke with $agent-architecture' names the domain but describes no concrete capability — the only action is the meta-instruction to invoke the agent itself. It sits between anchor 1 (no concrete actions) and anchor 2 (domain named, actions minimal/generic); not 1 because it does name the domain and give an invocation command, not 3+ because there is no 'what it does' beyond the domain label.

Completeness

Has only a vague 'what' ('Agent skill for architecture' — it never states it designs system architectures, interfaces, or deployment plans) and no 'when' clause whatsoever; the missing-'Use when' cap of 3 applies and it falls to anchor 2 ('vague what and no when'). Not 1 because the domain and invocation are stated; not 3 because the 'what' is a domain label, not a clear capability statement.

Trigger Term Quality

The only natural keyword is 'architecture'; there are no trigger phrases or synonyms a user would actually say ('design the system architecture', 'tech stack', 'scalability', 'component design'). Matches anchor 2 ('one or two generic keywords; missing the natural phrases users say') — not 3 because even common variations are absent, not 1 because 'architecture' is a relevant, naturally-occurring term.

Distinctiveness Conflict Risk

'Architecture' is a very broad term with high overlap risk against design, planning, scaffolding, and code-review skills, and nothing in the description (e.g., SPARC methodology, system design, deliverables) narrows the niche. Matches anchor 2 ('very broad; high overlap risk') — not 3 because no distinct trigger differentiates it from similar skills.
