Discovery

22%

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 description is severely incomplete - it only specifies a trigger phrase without explaining what the skill actually does. While 'plan harder' is a distinctive trigger, Claude cannot make an informed decision about using this skill because there's no information about its capabilities or purpose.

Suggestions

Add a clear description of what the skill does before the trigger clause (e.g., 'Creates detailed, multi-step implementation plans with risk analysis and contingencies.')

Expand trigger terms to include natural variations users might say (e.g., 'detailed plan', 'thorough planning', 'comprehensive plan', 'plan in depth')

Restructure to follow the pattern: '[What it does]. Use when [trigger conditions].' to ensure both components are present

DimensionReasoningScore

Specificity

The description contains no concrete actions whatsoever - it doesn't describe what the skill does, only when to trigger it. 'Plan harder' is not a capability description.

1 / 3

Completeness

The description only addresses 'when' (user says 'plan harder') but completely omits 'what' - there is no explanation of what this skill actually does or what capabilities it provides.

1 / 3

Trigger Term Quality

Contains one explicit trigger phrase 'plan harder' which is specific, but lacks any variations or related natural terms users might say (e.g., 'detailed planning', 'thorough plan', 'comprehensive planning').

2 / 3

Distinctiveness Conflict Risk

The specific trigger phrase 'plan harder' is distinctive and unlikely to conflict with other skills, but without knowing what the skill does, it's unclear if it might overlap with other planning-related skills.

Implementation

92%

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

This is a well-crafted skill with excellent actionability and workflow clarity. The phased approach with explicit validation steps (user input, gotcha review, subagent review) demonstrates strong process design. The main weakness is the inline template which adds length but could reasonably be kept inline for a planning skill.

DimensionReasoningScore

Conciseness

The skill is lean and efficient, avoiding explanations of concepts Claude already knows. Every section serves a purpose with no padding or unnecessary context.

3 / 3

Actionability

Provides concrete, specific guidance throughout with clear examples (good vs bad task definitions), explicit tool usage (request_user_input), and a complete template that's copy-paste ready.

3 / 3

Workflow Clarity

Clear 6-phase sequence (Phase 0-5) with explicit validation checkpoints including user clarification, gotcha identification, and subagent review. Each phase has clear purpose and builds on previous work.

3 / 3

Progressive Disclosure

Content is well-organized with clear sections, but the plan template is quite long and could be split into a separate reference file. The skill is self-contained but borders on monolithic.
