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 strong skill description that clearly identifies its niche (App Store Optimization via store.config.json), includes an explicit 'Use when' clause with good trigger terms, and is highly distinctive. The main weakness is that the core capability is described somewhat generically as 'optimize' rather than listing specific concrete actions (e.g., 'generate keyword lists, write compelling subtitles, localize metadata across languages').
Suggestions
Replace the vague 'Optimize' with more specific concrete actions, e.g., 'Generates keyword lists, writes compelling titles and subtitles, crafts promotional descriptions, and localizes metadata across languages in store.config.json for ASO.'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (App Store Optimization) and mentions specific metadata fields (keywords, titles, subtitles, descriptions, localizing), but the core action is just 'optimize' which is somewhat vague. It doesn't list multiple distinct concrete actions like 'extract, fill, merge' — it's more of a single action with enumerated targets. | 2 / 3 |
Completeness | Clearly answers both 'what' (optimize Apple App Store metadata in store.config.json for ASO) and 'when' (explicit 'Use when' clause listing specific triggers like working with store.config.json, App Store keywords, titles, subtitles, descriptions, or localizing app metadata). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger terms: 'store.config.json', 'App Store', 'ASO', 'keywords', 'titles', 'subtitles', 'descriptions', 'localizing', 'app metadata', 'visibility', 'downloads'. These are terms users would naturally use when needing this skill. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with a clear niche: Apple App Store metadata optimization specifically in store.config.json files. The combination of ASO, store.config.json, and App Store metadata makes it very unlikely to conflict with other skills. | 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 ASO skill with excellent concrete guidance including character limits, formatting rules, a complete JSON schema, and a well-constructed before/after example. The workflow is clear with validation checklists. Main weaknesses are moderate verbosity (some content Claude would already know, like language codes and basic keyword research concepts) and the monolithic structure that could benefit from splitting detailed reference material into separate files.
Suggestions
Move the Apple language codes table and cross-localization details into a separate reference file (e.g., LOCALIZATION.md) to reduce the main skill's token footprint.
Trim explanatory content Claude already knows, such as what relevance/volume/competition mean in keyword research, and the general description of ASO at the top.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Generally efficient with good use of tables and lists, but includes some information Claude already knows (e.g., explaining what ASO is, listing all Apple language codes, explaining what relevance/volume/competition mean in keyword research). The language codes table and some explanatory text could be trimmed. | 2 / 3 |
Actionability | Provides concrete, actionable guidance throughout: specific character limits, exact formatting rules (no spaces after commas), a complete JSON schema for store.config.json, a detailed before/after example with specific issues and fixes, and executable CLI commands. The keyword rules are specific and copy-paste ready. | 3 / 3 |
Workflow Clarity | The 4-step optimization workflow is clearly sequenced with checklists at analysis and validation stages. The validation step includes specific checks (character counts, no duplicates, no prohibited terms). For this type of non-destructive metadata editing task, the workflow is appropriately structured with feedback loops. | 3 / 3 |
Progressive Disclosure | Content is well-organized with clear headers and logical sections, but it's a long monolithic file (~180 lines) with no bundle files to offload detail. The language codes table, cross-localization details, and full schema could be split into referenced files. References to external resources exist but no internal file splitting is used. | 2 / 3 |
