Use when creating a changeset, preparing a release, or bumping versions. Covers which packages to reference, how to write user-facing changeset descriptions, the release automation flow, and the npm/Docker version sync requirement. (project)

Discovery
89%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a solid skill description with clear trigger guidance and a well-defined niche. Its main weakness is that the capabilities are described more as topic coverage areas ('Covers which packages to reference...') rather than concrete actions the skill enables. The trigger terms and explicit 'Use when' clause are strong.
Suggestions
Reframe the 'Covers...' clause into concrete actions, e.g., 'Creates changeset files, writes user-facing release descriptions, manages npm/Docker version synchronization' instead of describing what it covers.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description names the domain (changesets, releases, version bumping) and mentions several aspects it covers (packages to reference, user-facing descriptions, release automation flow, npm/Docker version sync), but these read more like topic areas than concrete actions. It doesn't list specific actionable operations like 'create changeset files' or 'update package.json versions'. | 2 / 3 |
Completeness | Explicitly answers both 'what' (covers package references, user-facing changeset descriptions, release automation flow, npm/Docker version sync) and 'when' ('Use when creating a changeset, preparing a release, or bumping versions'). The 'Use when...' clause is present and clear. | 3 / 3 |
Trigger Term Quality | Includes strong natural trigger terms users would say: 'changeset', 'release', 'bumping versions', 'npm', 'Docker', 'version sync'. These cover the key vocabulary a user would naturally use when needing this skill. | 3 / 3 |
Distinctiveness Conflict Risk | The combination of changesets, release automation, and npm/Docker version sync creates a very specific niche. This is unlikely to conflict with generic coding or deployment skills due to the precise focus on changeset workflows and version management. | 3 / 3 |

Implementation
77%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a solid, actionable skill that clearly instructs Claude on how to create changesets and understand the release pipeline. Its main weakness is redundancy — the internal package restriction is stated three times — and some infrastructure details in Version Synchronization that aren't directly actionable for the changeset creation task. The concrete examples, clear rules, and checklist make it highly usable despite the verbosity.
Suggestions
Remove the duplicate paragraph about internal packages in 'Writing the Description' since the same rule is already stated in 'Rules' and the checklist.
Consider trimming the Version Synchronization section to only the actionable constraint (Docker version must match npm version) and move registry/architecture details to a separate reference file if needed.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content has some redundancy — the rule about only referencing `@cloudflare/sandbox` and never internal packages is stated three times (in Rules, Writing the Description, and Checklist). The Version Synchronization section includes some infrastructure details (ARM Macs, registry namespaces, image variants) that are informational but not directly actionable for creating changesets. Overall mostly efficient but could be tightened. | 2 / 3 |
Actionability | Provides concrete, copy-paste-ready examples: exact file path format for changesets, exact markdown frontmatter syntax, good/bad description examples, and a clear checklist. Claude would know exactly what to produce when asked to create a changeset. | 3 / 3 |
Workflow Clarity | The release automation flow is clearly sequenced (merge PR → Version Packages PR → automated publish steps). The changeset creation process is unambiguous with explicit rules. Validation is covered by noting that pre-commit hooks and CI enforce the internal package rule. The checklist serves as a final validation checkpoint. | 3 / 3 |
Progressive Disclosure | The content is well-structured with clear headers and logical sections, but it's somewhat long for a single file with no references to supporting documents. The Version Synchronization details and Release Automation internals could potentially be split out, though the lack of bundle files means this is the only document. For a standalone skill, the organization is reasonable but the inline detail level is slightly heavy. | 2 / 3 |
