85%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A dense, highly actionable migration playbook: concrete commands, exact metadata requirements, and an exemplary validate-and-fix loop. Its one structural weakness is that everything lives in one long SKILL.md — the metadata spec, mobile-safety rules, and validation checklist would serve better as separate reference files for progressive disclosure.
Suggestions
Move the pyproject.toml required-fields/metadata-inference specification (workflow steps 3-5) into a reference file such as references/metadata.md and link it with 'See [metadata.md](references/metadata.md) for the full field spec', keeping only a short field summary in SKILL.md.
Extract the 14-item validation checklist (step 11) into references/validation.md, leaving the core loop (compileall → ruff fix-until-pass → stale-path search → git status) inline so the SKILL.md workflow stays scannable.
Deduplicate section 6: the 'Apply this to all examples in the touched folder' sentence appears twice (lines 77 and 82); state it once at the top of the mobile-safety section.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Nearly every line carries project-specific convention (required pyproject fields, SafeArea rules, platform-verification steps) that Claude could not infer, so there is no conceptual padding. Minor trimming is possible: "Apply this to all examples in the touched folder (new, migrated, and already converted)" appears twice within section 6 (lines 77 and 82), and the validation checklist restates several workflow rules. This matches 'efficient; minor instances that could be trimmed' rather than the fully lean 5. | 4 / 5 |
Actionability | Guidance is concretely executable throughout: exact commands (`rg --files <target_dir>`, `uv run ruff check`, `python -m compileall`), exact required pyproject fields per section, exact import forms, and precise file-move rules (`foo.py` → `foo/main.py`). For an instruction-only skill this is fully actionable and covers the common cases, matching the top anchor; the absence of a code template is not penalized since the guidance is specific. | 5 / 5 |
Workflow Clarity | An 11-step numbered workflow with a dedicated validation step containing explicit feedback loops ("run ruff check ... and fix violations until it passes", re-run compileall, search stale paths, check git status, run targeted tests) — exactly the validate → fix → retry pattern the top anchor requires. Destructive/batch operations (deleting control-level `__init__.py`, mass file moves) are guarded by explicit confirmations, so the destructive-operations cap does not apply. | 5 / 5 |
Progressive Disclosure | The skill is a single ~145-line file with no bundle files; all sections are clearly headed, but dense reference-style content (the full pyproject metadata field spec, the mobile-safety rules, and the 14-item validation checklist) is inlined in SKILL.md when it would navigate better as one-level-deep reference files. This matches 'some structure but could be better organized; content that should be separate is inline' — above the unstructured 2, below the well-split 4. | 3 / 5 |
