Quality

Content

87%

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

A well-organized, actionable, token-efficient workflow body whose only real gap is the absence of an explicit verification checkpoint after merging destructive changes into main specs.

Suggestions

Add an explicit validation step after applying changes (e.g., re-read the updated main spec to confirm requirements match the delta intent and that the result is well-formed) before showing the summary, turning the workflow into a validate->fix->retry loop.

Make idempotency checkable: instruct Claude to verify that re-running produces no further diff, rather than only asserting idempotency as a guardrail.

DimensionReasoningScore

Conciseness

The body is lean and structured with bullets and short steps, assumes Claude's competence, and reserves explanation for the genuinely skill-specific 'Intelligent Merging' concept rather than padding with basics Claude already knows.

3 / 3

Actionability

It gives concrete, copy-paste-ready guidance: exact file paths (openspec/changes/<name>/specs/*/spec.md, openspec/specs/<capability>/spec.md), a real command (openspec list --json), a named tool (AskUserQuestion), and a worked delta-spec format example — fully actionable for an instruction-only skill.

3 / 3

Workflow Clarity

Steps 1–4 are clearly sequenced, but editing main specs is a destructive/batch operation with no explicit verification checkpoint (only a summary), so per the rubric's feedback-loop guidance workflow clarity is capped at 2 rather than reaching the explicit-validation level above.

2 / 3

Progressive Disclosure

No bundle files exist and the skill is self-contained, organized into clearly labeled sections (Steps, Delta Spec Format Reference, Key Principle, Output, Guardrails) with no nested references, satisfying the well-organized-sections bar for a reference-free skill.

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.

A solid, clearly triggered description that answers both what and when for a distinct openspec niche. Its main weakness is narrow trigger-term coverage and a single stated action rather than an enumerated set.

Suggestions

Add a couple of natural trigger phrasings users might say (e.g., 'apply a change to specs', 'merge delta specs into main specs') to broaden trigger-term coverage.

List the concrete sub-actions the sync performs (add, modify, remove, rename requirements) to lift specificity beyond a single 'sync' verb.

DimensionReasoningScore

Specificity

The description names the domain and a single concrete action ("Sync delta specs from a change to main specs") but does not list multiple distinct actions, matching the 'names domain and some actions' anchor rather than the 'lists multiple specific concrete actions' level above.

2 / 3

Completeness

It states both what the skill does ("Sync delta specs from a change to main specs") and an explicit when ("Use when the user wants to update main specs with changes from a delta spec, without archiving the change"), clearly answering both with an explicit trigger.

3 / 3

Trigger Term Quality

It includes relevant openspec-specific phrasing ("update main specs with changes from a delta spec") but offers only narrow coverage with few natural variations, fitting the 'some relevant keywords but missing common variations' anchor and falling short of broad natural-term coverage.

2 / 3

Distinctiveness Conflict Risk

It carves a clear openspec niche and the "without archiving the change" clause disambiguates it from an archiving skill, making conflicts unlikely; it is not the 'somewhat specific but could overlap' level below.
