Quality

Content

86%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.

A tightly structured, actionable skill body that leads with a copy-paste example and defers deeper recipes to clearly named external references. The main gap is the absence of an explicit validation/verification checkpoint in the workflow.

Dimension	Reasoning	Score
Conciseness	The body is efficient and assumes TypeScript/mod competence, but a few explanatory lines (e.g. the one-line result-type glosses) could be trimmed to reach fully lean.	4 / 5
Actionability	It provides a complete, copy-paste-ready default command with registration, capability guard, and concrete result-type definitions covering the common cases.	5 / 5
Workflow Clarity	A clear five-step sequence with a terminal user-facing checkpoint (tell path + run /reload), but no explicit validate-then-proceed feedback loop; the destructive/batch cap does not apply to command registration.	4 / 5
Progressive Disclosure	Well-organized sections (decision table, workflow, default command, result types, rules) with clearly signaled one-level-deep references to sibling skill recipes in the closing "More recipes" list.	5 / 5

Description

87%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.

A strong, third-person description that clearly pairs a concrete capability statement with explicit, varied trigger phrasing. Minor gains are possible by adding a few more action verbs or natural synonyms.

Dimension	Reasoning	Score
Specificity	"Creates, edits, and enables" names three concrete actions on a specific domain (mod-provided slash commands); not quite the comprehensive multi-action list of the 5 anchor, so it sits at 4.	4 / 5
Completeness	It explicitly states both what it does ("Creates, edits, and enables…slash commands") and when to use it ("Use when the user asks to add a custom /command…") with concrete trigger phrases.	5 / 5
Trigger Term Quality	Phrases like "custom /command", "slash command", "command shortcut", and "scoped conversation-backed command" give good natural-term coverage with synonyms, but a few common variations are absent.	4 / 5
Distinctiveness Conflict Risk	The narrow niche of "Letta Code mod-provided slash commands" with specific mod/panel triggers makes conflict with other skills minimal.	5 / 5
	Total	18 / 20 Passed
