Quality

Content

100%Weight 40%Scale 1-3

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, lean skill body: actionable numbered steps with concrete thresholds and outputs, explicit rollback/validation checkpoints for a risky cutover, and clean progressive disclosure to real reference files. It is an instruction-only skill but its guidance is specific enough to act on without code.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence, naming techniques (strangler fig, traffic shadowing) without explaining them; every section earns its place with no padded concept explanations.

3 / 3

Actionability

For an instruction-only skill the guidance is concrete and specific: named tools (Grep, Read), concrete thresholds (1% canary, 10/25/50/100% ramp, >2% 5xx rollback), and named output artifacts (router.js, shadow-compare.js, endpoint-mapping.json).

3 / 3

Workflow Clarity

An 8-step sequence culminates in an explicit phased cutover (shadow -> canary -> ramp -> decommission) with automatic rollback triggers and a validation step (integration tests plus legacy/target response comparison), providing the feedback loops a destructive cutover requires.

3 / 3

Progressive Disclosure

The body is an overview that clearly signals one-level-deep references to real bundle files (references/implementation.md, errors.md, examples.md — all present), with content appropriately split rather than inlined.

Description

90%Weight 40%Scale 1-3

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that clearly states what the skill does and when to use it, with natural trigger phrases. Its only gap is specificity: it states one primary action rather than enumerating several concrete capabilities.

DimensionReasoningScore

Specificity

The description names the domain ('API migrations between versions, platforms, or frameworks') and a concrete action ('Implement... with minimal downtime'), but offers only one main action rather than the multiple specific concrete actions the top anchor calls for.

2 / 3

Completeness

It explicitly answers both 'what' ('Implement API migrations... with minimal downtime') and 'when' ('Use when upgrading APIs between versions' plus explicit trigger phrases), matching the top anchor.

3 / 3

Trigger Term Quality

It lists natural phrases a user would actually say ('migrate the API', 'upgrade API version', 'migrate to new API'), giving good coverage of the common variations users would voice.

3 / 3

Distinctiveness Conflict Risk

API migration is a clear niche with distinct, specific triggers ('migrate the API', 'upgrade API version') unlikely to fire for unrelated skills.
