cds-migrator-transform

Use when a CDS change in **cds-web**, **cds-common**, **cds-mobile**, **web-visualization**, or **mobile-visualization** needs a **jscodeshift** migration in `packages/migrator` to update callers or mitigate breaking API or import moves (add or change a transform, tests, or preset entry).

Quality

Content

81%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 well-sequenced, actionable workflow with strong validation checkpoints and a closing checklist. It is slightly long and would benefit from a copy-paste transform skeleton to push actionability and conciseness toward the top anchor.

Suggestions

Add a minimal copy-paste transform skeleton (default export, transformLogger/addTodoComment imports, getPackageScopeFromOptions usage) so the common case is fully executable without reverse-engineering reference files.

Tighten the verbose import-path/depth-pattern guidance in step 5 into a compact table (from-location → relative import) to trim length.

Consider moving the long §6 tests/fixtures detail into a referenced doc and keeping only the inline-first default in SKILL.md to improve progressive disclosure.

DimensionReasoningScore

Conciseness

Efficient and assumes Claude's competence (no primers on what jscodeshift is), but at ~150 lines some guidance and phrasing could be tightened without losing meaning.

4 / 5

Actionability

Provides concrete paths, exact import names, depth patterns, and runnable CLI commands, though no full copy-paste transform code example is included for the common case.

4 / 5

Workflow Clarity

A clear 7-step numbered sequence with explicit validation checkpoints ('Stop and confirm', 'Run until green', test/typecheck/lint), idempotency requirement, and a final checklist with feedback loops.

5 / 5

Progressive Disclosure

Well-organized into clearly signaled sections with one-level-deep references to in-repo docs and example files; no skill bundle files exist, and content is appropriately self-contained.

Description

92%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 highly specific, complete, and distinctive, naming concrete actions, the target packages, and an explicit 'Use when…' trigger. Minor synonym gaps (e.g. 'codemod') keep trigger_term_quality just below the top anchor.

DimensionReasoningScore

Specificity

Lists multiple concrete actions (jscodeshift migration, update callers, mitigate breaking API or import moves, add or change a transform, tests, or preset entry) scoped to a specific package path, giving comprehensive coverage.

5 / 5

Completeness

Explicitly answers both 'what' (jscodeshift migration to update callers / mitigate breaking API or import moves) and 'when' ('Use when a CDS change in [packages] needs…') with concrete triggers.

5 / 5

Trigger Term Quality

Natural trigger phrasing ('Use when a CDS change… needs a jscodeshift migration') plus relevant keywords (migration, transform, preset, cds-web/cds-common/cds-mobile), though synonyms like 'codemod' are absent.

4 / 5

Distinctiveness Conflict Risk

A clear niche (jscodeshift transforms under packages/migrator for a specific set of CDS packages) with distinct triggers and minimal overlap risk with other skills.
