Discovery

N/A

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

Something went wrong

Implementation

87%

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

This is a well-crafted skill that provides concrete, actionable templates for API changelog documentation. The content is appropriately concise and includes useful before/after examples. The main weakness is the migration workflow lacks explicit validation steps or error recovery guidance for what is potentially a risky operation.

Suggestions

Add validation checkpoints to the migration guide template (e.g., 'Test endpoint responses match expected v3 format before proceeding')

Include a rollback procedure or verification step after each migration phase to catch issues early

DimensionReasoningScore

Conciseness

Content is lean and efficient with no unnecessary explanations. Every section provides direct, actionable templates without explaining what APIs or changelogs are.

3 / 3

Actionability

Provides concrete, copy-paste ready templates including markdown structure, JSON examples, and migration steps. The before/after code examples are immediately usable.

3 / 3

Workflow Clarity

Migration steps are listed but lack validation checkpoints. No guidance on verifying migration success or rollback procedures if something fails during the upgrade process.

2 / 3

Progressive Disclosure

For a skill of this size (~60 lines), content is well-organized into logical sections (structure, deprecation, policy, migration, best practices) without needing external file references.
