Quality

Content

82%Weight 40%Scale 1-5

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

The body is a high-quality, code-forward reference with executable examples covering the common bundler-test cases and clear topical organization. Its only weakness is mild redundancy in the 'Key Points' summary and an implicit rather than explicit workflow sequence.

Suggestions

Remove the redundant 'Key Points' bullets that restate dedent/capture/relative-paths/snapshot guidance already shown in the examples, or fold them into the relevant sections.

Add a brief numbered 'Authoring a test' sequence (define files → set options → add run/assertions → execute with `bun bd test`) to make the workflow explicit.

Consider moving the full Bundler Options and Runtime Verification option catalogs into a reference file linked from the overview to tighten the main body.

DimensionReasoningScore

Conciseness

The body is mostly lean reference-style content with minimal prose and code-forward examples, but the closing 'Key Points' section repeats information already shown above (dedent, capture, relative paths, snapshots), which could be trimmed.

4 / 5

Actionability

Provides fully executable, copy-paste-ready code examples across common cases (basic usage, file setup, runtime verification, DCE, capture, onAfterBundle) plus concrete run commands.

5 / 5

Workflow Clarity

The single action (write an itBundled test) is unambiguous and a complete worked example anchors the pattern, but the content is organized by feature rather than as an explicitly sequenced workflow with validation checkpoints.

4 / 5

Progressive Disclosure

Well-organized with clear section headers and no nested references, all content appropriately inline for a reference skill; minor gaps only (the full options catalog could arguably live in a separate file).

Description

87%Weight 40%Scale 1-5

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

The description is concise, specific, and explicitly covers both capability and trigger conditions with strong natural keywords. It is well-scoped to a distinct niche with low conflict risk.

DimensionReasoningScore

Specificity

Names the domain ('bundler tests') and concrete tooling ('itBundled/expectBundled in test/bundler/'), which lists specific actions with only minor coverage gaps; not a full 5 because the action is essentially a single one (writing tests) rather than multiple distinct concrete actions.

4 / 5

Completeness

Explicitly answers both 'what' ('Guides writing bundler tests using itBundled/expectBundled in test/bundler/.') and 'when' ('Use when creating or modifying bundler, transpiler, or code transformation tests.') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural terms a user would say ('bundler tests', 'transpiler', 'code transformation tests') plus specific identifiers; a few synonyms or file extensions are missing, so it is not a comprehensive 5.

4 / 5

Distinctiveness Conflict Risk

A clear niche (Bun bundler tests via itBundled/expectBundled) with distinct triggers; minimal overlap risk with other skills.
