Conciseness

The body is mostly efficient procedural instruction with no explanations of concepts Claude already knows, but Step 0 and Step 4 contain dense, hard-to-parse sentences (e.g. "newly discovered areas are inside the envelope only when they have one of the relationships above and evidence shows they can change the supported cause set, coverage judgment, or counter-evidence") and the Execution Gate, Step 4, and Completion Criteria partially repeat each other. This fits anchor 3 (mostly efficient, could be tightened) rather than anchor 4's minor-trims-only level.

Actionability

Concrete, copy-ready Agent invocation blocks specify exact subagent_type, description, and prompt field templates; expected-output schemas name specific JSON fields; and two full report templates are provided. Minor gaps keep it at anchor 4: the prerequisite skills ("llm-friendly-context", "subagents-orchestration-guide") are referenced by bare name without paths, and the investigator/verifier/solver subagent types are assumed to exist.

Workflow Clarity

Steps 0-7 are strictly ordered behind an explicit Execution Gate, with a Step 2 validation checklist, verifier coverage criteria, coverageDisposition branching, and a defined feedback loop (verifier names gaps → re-run investigator on gaps → re-verify), plus a final completion checklist. This matches anchor 5's explicit validation, error-recovery loops, and checklists; the only minor fuzz is "design decision gate when applicable" in the overview diagram, which Step 5 substantiates.

Progressive Disclosure

The single file is well organized with clear step headers, code blocks, and templates, and no bundle files exist to reference. It stays at anchor 4 rather than 5 because the ~225-line body inlines two full report templates that could live in reference files, and the two cross-skill references are bare names with no paths or signaling of where their content lives.

Specificity

The description lists three verbs ("Investigate problem", "verify findings", "derive solutions") but every object is abstract and no domain is named, placing it at anchor 2's generic-action level rather than anchor 3, which requires a concrete domain alongside the actions. It is above anchor 1 because distinct actions are named rather than one wholly vague claim.

Completeness

A rough "what" is present ("Investigate problem, verify findings, and derive solutions") but there is no "Use when..." clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. It is not 4 because the "when" is entirely absent rather than merely implicit or imprecise.

Trigger Term Quality

No natural user phrases such as "debug", "root cause", "diagnose", or "fix bug" appear; only generic words like "problem" and "solutions" are present, matching anchor 2 (one or two generic keywords, natural phrases missing). It avoids anchor 1 only because "investigate" and "verify" are domain-relevant verbs rather than pure technical jargon.

Distinctiveness Conflict Risk

"Investigate problem ... derive solutions" could describe almost any problem-solving, debugging, or planning skill, creating high overlap risk (anchor 2). It is not 1 because the investigate→verify→solve sequence sketches a diagnosis-specific niche, and not 3 because no domain term distinguishes it from adjacent skills.
