Conciseness

The body is lean and package-specific with no padding of concepts Claude already knows, though the Performance Characteristics and Performance Tips sections partially overlap and could be tightened. Not 5 because of that minor redundancy; not 3 because there is no unnecessary explanation of general concepts.

Actionability

Provides concrete type definitions, real function signatures, and executable usage snippets (config.paths assignment and useCachedGetMessagePathDataItems call). Not 5 because some signatures lack bodies and edge-case examples are absent; not 3 because the guidance is mostly executable rather than pseudocode.

Workflow Clarity

The usage flow (configure paths, call the cached hook, receive extracted items) is discernible from Common Patterns but is not presented as an explicit sequenced workflow with checkpoints. No destructive or batch operations are involved, so no validation cap applies. Not 4 because there is no explicit numbered sequence; not 2 because the flow is not absent.

Progressive Disclosure

A single self-contained file with no bundle directories, organized into clear, navigable sections (Overview, Path Syntax, Parsing, Data Extraction, React Integration, Usage by Panels, Common Patterns, Performance Tips). Not 5 because at ~115 lines there is no one-level-deep external reference structure to signal; not 3 because the structure is good and not buried.

Specificity

Lists several concrete capabilities ('path syntax, parsing grammar, data extraction from nested messages, and React hook integration') rather than vague language, though framed as knowledge domains instead of verb-actions. Not 5 because it lacks a comprehensive verb-action list; not 3 because it enumerates more than 1-2 concrete items.

Completeness

A clear 'what' is present (deep knowledge plus enumerated capabilities), but there is no explicit 'Use when...' clause; 'when' is only weakly implied via 'Shared across Plot, RawMessages, StateTransitions, and general panel agents'. Per the rubric guideline, a missing explicit trigger caps completeness at 3.

Trigger Term Quality

Relevant keywords ('message-path', 'Plot', 'RawMessages', 'StateTransitions', 'panel agents') are natural for this codebase but are technical jargon with no common-phrase synonyms or variations. Not 4 because natural variations are missing; not 2 because the terms are more than generic.

Distinctiveness Conflict Risk

Targets a clear niche (a specific package plus named panels) with distinct triggers and minimal conflict risk, though 'general panel agents' introduces minor overlap with related skills. Not 5 because of that residual overlap risk; not 3 because it is mostly distinct.
