Content
36%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is essentially a table of contents/index file that points to external rule files, but provides no actionable content itself. It lacks any concrete SQL examples, optimization techniques, or workflow guidance. The duplicated 'When to Use' section and meta-descriptive content waste tokens without adding value for Claude.
Suggestions
Add at least 3-5 concrete, high-impact optimization examples inline (e.g., common missing index patterns, RLS performance pitfalls) so the skill provides standalone value without requiring bundle files.
Define a clear workflow for query optimization: identify issue → analyze with EXPLAIN → apply fix → validate improvement, with specific commands at each step.
Remove the duplicated 'When to Use' section at the bottom and trim the introductory paragraph to be more direct.
Include at least one executable SQL example for the most critical category (Query Performance) so Claude has immediately actionable guidance.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content has some unnecessary padding — the 'When to Use' section appears twice (duplicated at top and bottom), the introductory paragraph explains what the guide is rather than providing actionable content, and the table of categories with priority/impact/prefix is meta-information that doesn't directly help Claude act. However, it's not egregiously verbose. | 3 / 5 |
Actionability | The skill provides no concrete SQL examples, no executable code, and no specific optimization techniques. It is entirely a meta-document pointing to other files (rules/*.md, AGENTS.md) without giving any actionable guidance itself. Claude would need to read those referenced files to actually do anything. | 2 / 5 |
Workflow Clarity | There is no workflow defined — no steps, no sequence, no validation checkpoints. The skill only describes a categorization system and file structure. For a performance optimization skill, there should be at least a basic workflow like: identify slow query → check EXPLAIN output → apply relevant rule → validate improvement. | 2 / 5 |
Progressive Disclosure | The skill references external files (rules/*.md, _sections.md, AGENTS.md) which suggests an attempt at progressive disclosure, but no bundle files are provided to verify these exist. The references are reasonably clear but the skill itself provides almost no standalone value — it's essentially just a table of contents with no useful content at the top level. | 3 / 5 |
