Conciseness

The phased structure avoids explaining concepts Claude already knows, but there is real redundancy: Phase 2's "Leverage External Sources" and "Online Research Methodology" subsections repeat the same instructions, Phase 3's subsections overlap, the environment-specific skill-mapping list (10 lines) will go stale, and a dated anecdote ("Google Photos Library API scopes were deprecated March 2025") is embedded as rationale rather than placed in a deprecated/old-patterns section. This is more than the "minor instances" of the 4 anchor but not the heavy concept-padding of the 2 anchor.

Actionability

There are genuinely concrete elements — exact glob patterns ("**/**/SKILL.md"), exact search-query templates ("[API name] deprecated [current year] sunset shutdown"), and a named tool (Context7 MCP) — but a significant portion of the body, especially Phase 3 ("Organize into clear categories", "Provide specific examples", "Deliver Actionable Guidance") and the Special Cases section, is abstract direction Claude would follow anyway. Concrete guidance is present but incomplete relative to the 4 anchor.

Workflow Clarity

The sequence is explicit and enforced ("Follow This Order": Phase 1 → 1.5 → 2 → 3) with decision branching based on skill coverage and a mandatory validation gate in Phase 1.5 ("Report findings before proceeding - do not recommend deprecated APIs"). No destructive or batch operations apply, so no cap. It falls short of the 5 anchor because there are no error-recovery feedback loops or checklists.

Progressive Disclosure

The body is well-sectioned with clear headers, entirely one level deep, with no nested or buried references (no bundle files exist). The skill is over 50 lines, so the simple-skill exception to score 5 does not apply, and the inline environment-specific skill-mapping list is minor content that could live in a separately updatable reference file — a minor organization gap matching the 4 anchor.

Specificity

The description lists several actions ("research and gather external best practices, documentation, and examples", "finding official documentation, community standards", "synthesizing information from multiple sources") which would fit the 4 anchor, but it uses second person voice ("Use this agent when you need to research..."), which the judging guidelines penalize by reducing the specificity score by 1. The actions are also somewhat abstract (research/gather/synthesize) compared to concrete operations.

Completeness

Both what ("research and gather external best practices... synthesize") and when ("Use this agent when you need to research and gather external best practices...") are explicitly stated. However, the when-clause largely restates the capability rather than providing distinct concrete trigger scenarios, so it falls short of the 5 anchor's "concrete trigger phrases".

Trigger Term Quality

Natural terms users would say are present — "best practices", "documentation", "examples", "research", "community standards" — giving good keyword coverage. A few natural variations are missing (e.g., "conventions", "how to implement X properly", "industry standards" as a trigger rather than an outcome), so it does not reach comprehensive coverage.

Distinctiveness Conflict Risk

The niche (best-practices research and synthesis) is somewhat specific, but the scope claim "for any technology, framework, or development practice" is broad and would overlap with general web-research, documentation-lookup, and code-review skills. It is more specific than the 2 anchor's generic breadth, but not mostly distinct as the 4 anchor requires.
