version-sync

Migrate an out-of-tree LLVM project to a new LLVM version (e.g., LLVM 21 → 22). Covers CMake bump, common LLVM 22 API breakages, header moves, pass renames, and opaque pointer migration.

Quality

Content

85%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 highly actionable with a clear, validated multi-step workflow and a useful checklist. Its main weakness is progressive disclosure: a large monolithic file where reference tables could be offloaded to a bundle file.

Suggestions

Move the large rename/move tables (Steps 5–7) into a references/ file (e.g. LLVM22-API-CHANGES.md) and link to it from SKILL.md to improve progressive disclosure.

Trim "Still works" / "(unchanged)" table rows that add no migration signal.

Consider adding a brief validation gate between Step 5 and Step 6 (e.g. rebuild after each category fix) to reinforce the fix→rebuild→verify loop.

DimensionReasoningScore

Conciseness

Mostly lean — tables of old→new mappings, commands, and a checklist assume Claude's LLVM knowledge; minor padding in "Still works" / "(unchanged)" table entries that could be trimmed.

4 / 5

Actionability

Fully executable throughout: concrete git/cmake/opt commands, before/after code snippets, and a copy-paste checklist covering the common migration cases.

5 / 5

Workflow Clarity

Steps 0–11 are clearly sequenced with explicit validation checkpoints (collect build errors in Step 2, run tests in Step 9, fix failures) and a final checklist, matching the anchor for clear sequences with feedback loops.

5 / 5

Progressive Disclosure

Well-sectioned single file, but ~215 lines with no bundle files and large inline reference-style tables (header moves, API renames, pass-name changes) that could be split into a reference file; the only cross-reference is to another skill (add-npm-pass), not to bundle material.

Description

75%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 specific and clearly niche-targeted, but it lacks an explicit "Use when..." trigger clause, which caps completeness. Adding a concrete trigger phrase would round it out.

Suggestions

Add an explicit 'Use when...' clause, e.g. 'Use when upgrading an out-of-tree LLVM project to LLVM 22 from versions 19, 20, or 21.'

Include synonyms like 'upgrade' or 'port' alongside 'migrate' to broaden natural trigger coverage.

Mention the target version (LLVM 22) more prominently as a trigger term rather than only inside the parenthetical example.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "CMake bump, common LLVM 22 API breakages, header moves, pass renames, and opaque pointer migration" — giving comprehensive coverage of the migration task.

5 / 5

Completeness

Has a clear "what" but no explicit "Use when..." trigger clause; the "when" is only weakly implied by the example version bump, capping completeness at 3 per the rubric guideline.

3 / 5

Trigger Term Quality

Includes natural terms users would say ("Migrate", "out-of-tree LLVM project", "LLVM 21 → 22") but omits common synonyms like "upgrade" or "port".

4 / 5

Distinctiveness Conflict Risk

Targets a narrow niche — out-of-tree LLVM project migration to a specific version — with distinct triggers and minimal overlap with other skills.
