Quality

Content

72%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is an efficiently organized, non-padded set of constraints and defaults that fits a simple single-file skill well, but it lacks complete executable code examples and the validation checkpoints the rubric expects for database-involved workflows.

Suggestions

Add one small executable code block (e.g., a minimal PDO helper or the index.php router switch) to make the guidance copy-paste ready.

Insert a verification checkpoint in the Workflow (e.g., confirm the SQLite database file was created / test a route after writing index.php) to satisfy the feedback-loop expectation for database operations.

DimensionReasoningScore

Conciseness

The body is lean bullet-pointed guidance that assumes Claude's competence ("Use modern syntax (named arguments, match, readonly properties)", "No exec / shell_exec") with no padding or explanation of basic PHP concepts; every line earns its place.

3 / 3

Actionability

Guidance names concrete APIs and patterns (PDO prepared statements, htmlspecialchars(), switch on $_SERVER['REQUEST_URI'], session_start()), but it stops short of the fully executable, copy-paste-ready code blocks the score-3 anchor requires.

2 / 3

Workflow Clarity

The Workflow section lists four sequenced steps, but there are no validation/verification checkpoints; since the skill touches SQLite database operations, the rubric caps workflow clarity at 2 for missing feedback loops.

2 / 3

Progressive Disclosure

This is a short, single-file skill (~50 lines) with well-organized sections (Constraints, File layout, Security defaults, Workflow, Don't) and no need for external references, matching the rubric's allowance for a score-3 on simple well-structured skills.

Description

57%

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 clearly states what the skill does and carves out a distinct PHP-on-device niche, but it omits an explicit 'when to use' trigger and lists only one action, leaving trigger coverage and completeness short of the top anchors.

Suggestions

Add an explicit 'Use when...' clause naming natural triggers (e.g., when the user wants a PHP backend, admin panel, or a WordPress-like flow without WordPress).

Expand the action list beyond 'Build' to concrete capabilities (e.g., build, route requests, query SQLite, add session-based auth) to lift specificity.

DimensionReasoningScore

Specificity

"Build a PHP web app that runs on the on-device PHP 8.4 runtime" names the domain and a single action (build), but lists only one action rather than the multiple concrete actions a score-3 anchor expects.

2 / 3

Completeness

The what is clear (build a PHP web app on the on-device runtime), but there is no explicit 'Use when...' clause; per the rubric a missing trigger clause caps completeness at 2.

2 / 3

Trigger Term Quality

"PHP web app" and "PHP 8.4 runtime" are natural terms, but coverage is thin — common variations like backend, API, or admin panel that a user might actually say are absent from the description.

2 / 3

Distinctiveness Conflict Risk

The PHP-on-device-runtime niche is specific and unlikely to overlap with other skills; the domain constraint (on-device PHP 8.4) makes mistaken triggering unlikely.
