Quality

Content

88%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-structured, highly actionable decision reference with clear sequencing and a built-in fallback loop, held back only by minor redundancy between the model tables/lists and the absence of any split-out reference file.

DimensionReasoningScore

Conciseness

The body is information-dense and relies heavily on token-efficient tables; it assumes Claude's competence and does not explain basic concepts. Minor duplication (the 'Valid Models' list restates models already in the fallback chains and tables, and the role-table 'Why' column adds light rationale) keeps it just below a 5.

4 / 5

Actionability

Guidance is concrete and copy-paste ready: specific model strings, an explicit spawn parameter block, a ready-to-use acknowledgment format, and worked examples covering common cases (backend dev, user override, complex refactor, scribe).

5 / 5

Workflow Clarity

The 4-layer hierarchy is explicitly sequenced ('Check these layers in order — first match wins') and the fallback chain forms a clear error-recovery loop (silent retry, max 3, then nuclear fallback) with explicit rules; this is not a destructive/batch operation so no validation cap applies.

5 / 5

Progressive Disclosure

No bundle files exist and the skill is self-contained, which suits a single-file reference; sections are well organized (Context, Patterns, Examples, Anti-Patterns). Because it runs longer than 50 lines with inline reference lists (Valid Models, role mappings) that could optionally live in a separate file, it sits just below the top anchor.

Description

53%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 clearly states what the skill does and is reasonably distinct, but it omits any explicit 'when to use it' trigger guidance and relies on somewhat technical language rather than natural user phrases.

Suggestions

Add a 'Use when...' clause with concrete trigger phrases, e.g. 'Use when spawning agents in Team Mode, choosing models per task, or when the user asks to save costs or use a specific model.'

Include natural synonyms users would actually say ('pick a model', 'cheaper model', 'use opus/haiku') alongside the technical terms.

Spell out one or two more concrete actions (e.g., 'resolves model per agent, applies fallback chains on failure') to lift specificity.

DimensionReasoningScore

Specificity

Names the domain ('Per-agent model selection') and two concrete structural features ('4-layer hierarchy' and 'fallback chains'), but does not enumerate multiple specific actions, matching the 'names domain and 1-2 concrete actions' anchor.

3 / 5

Completeness

The 'what' is clearly stated (per-agent model selection via a 4-layer hierarchy with fallback chains), but there is no 'Use when...' clause or equivalent trigger guidance, which per the guidelines caps completeness at 3.

3 / 5

Trigger Term Quality

'model selection' and 'fallback chains' are relevant but technical; it lacks the natural phrasings a user would actually say (e.g., 'pick a model', 'save costs', 'choose a cheaper model'), so keyword coverage is partial.

3 / 5

Distinctiveness Conflict Risk

'Per-agent model selection with 4-layer hierarchy and fallback chains' carves a fairly distinct niche with specific structural triggers, leaving only minor overlap risk with adjacent orchestration skills.
