iwsdk-debug

Debug continuous behavior in WebXR scenes — physics, animations, collisions, game loops, or any real-time interaction that happens too fast for an agent to observe. Uses ECS pause/step/snapshot/diff to freeze time and inspect state frame by frame.

Content

100%

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 exemplar of a focused debugging skill: lean, highly actionable with exact tool signatures, a clearly sequenced workflow with verification checkpoints and feedback loops, and well-organized into navigable sections without unnecessary splitting.

DimensionReasoningScore

Conciseness

Lean and efficient with no padding or explanation of concepts Claude already knows; every section (workflow, tool table, patterns, notes) earns its place, with only minor justified reinforcement of critical gotchas.

3 / 3

Actionability

Provides concrete, copy-paste-ready tool calls with exact signatures and parameters (e.g., 'ecs_snapshot({ "label": "before" })', 'ecs_step(count, delta)') plus specific values (delta 0.016/0.0139) and component fields to inspect.

3 / 3

Workflow Clarity

A clear 10-step numbered sequence with explicit verification checkpoints (browser_screenshot at step 6, ecs_diff at step 8) and a feedback loop ('Repeat steps 5-8 until the behavior completes'), plus a Notes section documenting failure conditions.

3 / 3

Progressive Disclosure

A single cohesive, well-organized file split into clear sections (Core Workflow, Tool Reference, Stepping Guidelines, Patterns, Notes) with no nested references; appropriate for a focused single-purpose debugging skill.

Description

67%

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 is specific and distinctive, naming concrete ECS actions and a well-scoped debugging niche. It is held back by relying on technical jargon over natural trigger terms and omitting an explicit 'Use when...' trigger clause.

Suggestions

Add an explicit 'Use when...' trigger clause naming natural user phrasing (e.g., 'Use when debugging physics, animations, collisions, or game-loop issues in WebXR scenes that unfold too fast to observe').

Soften or contextualize the 'ECS pause/step/snapshot/diff' jargon so the description leads with terms a user would actually say rather than internal tool names.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('Uses ECS pause/step/snapshot/diff to freeze time and inspect state frame by frame') across named domains (physics, animations, collisions, game loops).

3 / 3

Completeness

Clearly states what the skill does, but the 'when' is only implied ('any real-time interaction that happens too fast for an agent to observe') with no explicit 'Use when...' trigger clause, which caps completeness at 2.

2 / 3

Trigger Term Quality

Includes some natural terms a user would say ('physics', 'animations', 'collisions', 'game loops'), but leans heavily on technical jargon ('ECS pause/step/snapshot/diff') users would not naturally say and misses common variations.

2 / 3

Distinctiveness Conflict Risk

A clear niche (WebXR continuous-behavior debugging via ECS time-control) with the distinctive 'happens too fast for an agent to observe' framing, unlikely to conflict with other skills.
