external-research

Search and inspect external sources for product, design, technical, or comparative research; verify provenance and turn findings into decisions. Use for requests to investigate online, research X posts or demos, compare approaches, or deepen a research task. Complements a research orchestrator without taking over its state or stop conditions.

Content

78%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.

An efficiently written, well-structured instruction-only skill: lean prose, a coherent research workflow with feedback loops and explicit stop conditions, and exemplary one-level-deep progressive disclosure into two real reference files. Its main weakness is actionability — much of the guidance is strategic direction without worked examples (sample queries, a filled-in provenance row) that would make it immediately executable.

Suggestions

Add one worked example of an expedition: a starting question, the actual queries tried, and how the gap drove the next query — this would concretize the abstract expedition loop for the actionability dimension.

Include a filled-in example row of the provenance table (e.g., a real-looking source with a Stated vs. Observed distinction and the resulting limit) so the evidence-strength labels are demonstrated, not just defined.

Make the expedition checkpoints explicit validation steps (e.g., "before recording a finding, confirm which label it earns: stated/observed/tested/inferred") to lift workflow clarity from implicit to explicit checkpoints.

DimensionReasoningScore

Conciseness

The ~110-line body is dense with directives and free of padding: no explanations of concepts Claude already knows, and every element (provenance table, Stated/Observed/Tested/Inferred taxonomy, stop conditions) earns its place — a clean anchor-5 match, above anchor 4's "minor instances of over-explanation".

5 / 5

Actionability

Concrete elements exist (one retrieval-target reformulation example, a usable provenance record table, a numbered expedition loop), but the guidance is largely strategic: no example search queries, no filled-in example table rows, and no tool-specific invocations, leaving key execution details missing per anchor 3 rather than anchor 4's "mostly executable guidance".

3 / 5

Workflow Clarity

The process is clearly sequenced (establish target → choose surface → expedition loop → provenance → convert to decisions → stop) with a real feedback loop ("choose the next search from the gap") and error recovery ("A correction changes the retrieval target immediately"), but checkpoints like "Inspect enough to support the intended claim" are implicit rather than explicit validation steps, matching anchor 4.

4 / 5

Progressive Disclosure

SKILL.md is a concise overview and both bundle files (references/platform-and-demo-research.md, references/research-integration.md) are real, clearly signaled with conditional read triggers ("For X and visual/Agent research, read..."), and one level deep — the reference files link only to external URLs, never to further bundle files — matching anchor 5.

Description

87%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.

A strong description: it names concrete actions, gives an explicit 'Use for' trigger clause with natural phrases, and even includes boundary guidance against a neighboring orchestrator skill. The only softness is mild abstraction in a couple of action phrases and a few missing colloquial trigger synonyms.

DimensionReasoningScore

Specificity

Lists several concrete actions ("Search and inspect external sources", "verify provenance", "research X posts or demos", "compare approaches"), but phrases like "turn findings into decisions" remain abstract, so it matches anchor 4 (several specific actions, minor gaps) rather than the mechanical comprehensiveness of anchor 5.

4 / 5

Completeness

Clearly answers both "what" (search/inspect external sources, verify provenance, turn findings into decisions) and "when" via an explicit "Use for requests to investigate online, research X posts or demos, compare approaches, or deepen a research task" clause with concrete trigger phrases — a direct anchor-5 match, clearly above anchor 4's weaker "when".

5 / 5

Trigger Term Quality

Natural user phrasing is well covered ("investigate online", "research X posts or demos", "compare approaches", "deepen a research task"), but a few common variations users would say (e.g., "look up", "search the web", "check online") are absent, matching anchor 4 rather than the comprehensive synonym coverage of anchor 5.

4 / 5

Distinctiveness Conflict Risk

Carves a clear niche (external online research with provenance verification) with distinct triggers, and the boundary sentence "Complements a research orchestrator without taking over its state or stop conditions" explicitly defuses conflict with the nearest neighboring skill — minimal conflict risk per anchor 5.
