Quality

Content

85%

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

The body is a well-structured, highly actionable instruction skill with concrete commands, a clear sequenced workflow, explicit stop points, and useful guardrails. The only notable weakness is verbosity in the Store selection paragraph, which could be condensed.

Suggestions

Tighten the Store selection paragraph by deferring the full command-flag enumeration to a short list or a reference note, keeping only the core '--store <id>' guidance inline.

Consider moving the detailed store-discovery behavior into a reference file so the main flow stays leaner, once bundle files are supported.

DimensionReasoningScore

Conciseness

The body is mostly lean and free of concept explanations Claude already knows, but the dense "Store selection" paragraph enumerating every command that takes --store is verbose and could be tightened, matching 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than the every-token-earns-its-place level-3 anchor.

2 / 3

Actionability

It provides fully executable, copy-paste-ready commands with concrete arguments (e.g., `openspec new change "<name>"`, `openspec status --change "<name>" --json`) plus a worked naming example, matching the 'fully executable code/commands; specific examples; copy-paste ready' anchor.

3 / 3

Workflow Clarity

A clearly numbered 6-step sequence with explicit STOP gates and guardrails for error cases (invalid name, existing change, do-not-advance) provides the validation checkpoints and feedback the level-3 anchor expects; the skill is non-destructive so no validate->fix->retry loop is required.

3 / 3

Progressive Disclosure

The skill is self-contained with no bundle files and is organized into clearly labeled sections (Store selection, Input, Steps, Output, Guardrails) with no nested or broken references, satisfying the simple-skill allowance for well-organized single-file content.

Description

75%

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 communicates what the skill does and when to use it, with an explicit trigger clause and a distinct OpenSpec-specific niche. Its main weakness is a single core action and jargon-heavy domain terms that limit specificity and natural trigger breadth.

Suggestions

Add one or two more concrete actions the skill performs (e.g., scaffolds the change directory, shows artifact status and next-step instructions) to lift specificity toward level 3.

Soften jargon in the trigger clause with more natural user phrasing or synonyms a non-expert would say when starting a structured spec-driven change.

DimensionReasoningScore

Specificity

It names the domain and one core action ("Start a new OpenSpec change using the experimental artifact workflow") but does not enumerate multiple distinct concrete actions, matching the 'names domain and some actions, but not comprehensive' anchor rather than the multi-action level-3 example.

2 / 3

Completeness

It explicitly states both what ("Start a new OpenSpec change using the experimental artifact workflow") and when ("Use when the user wants to create a new feature, fix, or modification with a structured step-by-step approach"), matching the anchor that clearly answers both with an explicit 'Use when...' trigger.

3 / 3

Trigger Term Quality

The trigger clause offers natural phrasing ("create a new feature, fix, or modification"), but the core concept "OpenSpec change" / "experimental artifact workflow" is technical jargon and the set of natural trigger terms is narrow, so it lands at 'some relevant keywords but missing common variations' rather than full coverage.

2 / 3

Distinctiveness Conflict Risk

The description is anchored to a specific tool niche ("OpenSpec change", "artifact workflow", openspec CLI), giving it distinct triggers unlikely to fire for unrelated skills, matching the 'clear niche with distinct triggers; unlikely to conflict' anchor.
