Quality

Content

67%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.

The body is a well-sequenced, actionable workflow with real openspec commands, explicit tool calls, and validation checkpoints for the batch artifact-creation loop. Its main weakness is conciseness: the context/rules constraint and step-4 instructions are repeated across multiple sections rather than stated once.

Suggestions

State the 'context/rules are constraints, not output content' rule once in the Artifact Creation Guidelines and reference it from step 4a and the guardrails instead of repeating it three times.

Merge or trim the 'Artifact Creation Guidelines' section so it does not restate the step 4a instructions; keep only guidance not already covered there.

Add a brief error-recovery branch for the 'verify each artifact file exists' guardrail (e.g., what to do if the file is missing or status is not 'done') to push workflow_clarity toward 5.

DimensionReasoningScore

Conciseness

The body is mostly efficient and avoids explaining concepts Claude already knows, but the 'context and rules are constraints for you, not file content' rule is restated in step 4a, the Artifact Creation Guidelines, and the guardrails, and the Guidelines section largely rehashes step 4, which is noticeable redundancy rather than a minor trim.

3 / 5

Actionability

It provides concrete, executable commands (openspec new/status/instructions) and names the exact tools (TodoWrite, AskUserQuestion) with the JSON fields to parse, fitting 'mostly executable guidance with minor gaps' — it stops short of a concrete filled-in artifact example.

4 / 5

Workflow Clarity

Steps 1-5 are clearly sequenced with validation checkpoints (re-run status after each artifact, check applyRequires status done, verify each file exists), and the batch-creation operation has validation so it is not capped at 3; it falls short of 5 because error-recovery when verification fails is not spelled out.

4 / 5

Progressive Disclosure

No bundle files are present and the single-file body is well-organized into Input/Steps/Output/Guidelines/Guardrails with no inlined content that belongs in a separate file; the minor organization gap is the Guidelines section restating step 4, keeping it below the clean anchor 5.

Description

62%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.

The description cleanly states both what the skill does and when to use it, with a clear OpenSpec niche and an explicit contrast against the manual step-by-step workflow. It is held back by listing only one concrete action and by trigger terms that are mostly domain jargon with limited natural-language variation.

Suggestions

Add 1-2 more concrete actions to the 'what' clause (e.g., 'scaffold the change, generate spec/tasks artifacts, and prepare for apply') to lift specificity toward 4-5.

Broaden trigger-term coverage with natural phrasings users actually say, such as 'scaffold a change', 'set up specs', or 'prepare implementation artifacts', beyond the OpenSpec jargon.

Optionally add a secondary 'when' trigger (e.g., 'or when the user wants to skip the interactive walkthrough') to push completeness toward anchor 5.

DimensionReasoningScore

Specificity

The description names the domain ('OpenSpec artifact creation') and one concrete action ('quickly create all artifacts needed for implementation') but does not enumerate several specific actions, matching the 'names domain and 1-2 concrete actions' anchor rather than the multi-action anchor at 4.

3 / 5

Completeness

It explicitly answers both what ('Fast-forward through OpenSpec artifact creation') and when ('Use when the user wants to quickly create all artifacts...') with a concrete trigger phrase, but the 'when' covers a single scenario rather than multiple trigger variations seen at anchor 5.

4 / 5

Trigger Term Quality

It includes relevant keywords ('artifacts', 'implementation', 'create') but leans on OpenSpec jargon and offers few natural synonyms or variations a user would say, fitting 'some relevant keywords but missing common variations'.

3 / 5

Distinctiveness Conflict Risk

'OpenSpec artifact creation' is a clear niche and 'without stepping through each one individually' distinguishes it from a sibling step-by-step skill, leaving only minor overlap risk with that closely related skill rather than the minimal conflict of anchor 5.
