Conciseness

Lean, imperative body with no explanation of concepts Claude already knows ('Default writable area is only plugin/plugins/<plugin_id>/', 'Runtime-triggered @plugin_entry handlers must be async def'). Not 5 because of repetition: the workspace path and 'Read references/core-plugin-contract.md' each recur several times across Non-Negotiables and the workflow sections.

Actionability

Gives concrete executable commands ('uv run neko-plugin init ...', 'uv run neko-plugin check <plugin_id|plugin_path>'), exact paths, and a named label scheme for review output. Not 5 because the init command is elided rather than shown in full, and no copy-paste-ready command examples cover the common create/validate cases.

Workflow Clarity

Each workflow (Create, Modify, Debug, Review, Escalate) is a clear numbered sequence with validation checkpoints ('Validate with the focused checks', 'Run the narrowest plugin-facing check', 'Run uv run neko-plugin check ... first'). Not 5 because there is no explicit validate-fail-fix-retry feedback loop after the validation steps, and no checklist tying the debug branches to their verification outcomes.

Progressive Disclosure

The body is a true overview with a Reference Map of eight files, each given a one-line purpose ('references/execution-boundary.md: write workspace, read context, and escalation rules'), all one level deep and all verified to exist in references/. Not 4 because navigation is explicit, appropriately split, and there is no inline content that belongs in a separate file.

Specificity

Lists many concrete actions ('create, modify, review, run, debug, inspect, document, validate, package, or reason about') against specific artifacts ('plugin.toml, plugin SDK usage, plugin UI surfaces, plugin CLI tooling, plugin runtime behavior'). Not score 4 because coverage spans both actions and target surfaces comprehensively rather than leaving minor gaps.

Completeness

Explicitly answers both: what ('Work on N.E.K.O plugins end to end' with a concrete action list) and when ('Use when the user asks to create, modify, review, run, debug...'). Matches the 5-anchor example structure with concrete trigger phrases; not 4 because the 'when' clause is fully explicit, not merely present.

Trigger Term Quality

Natural phrases users would say ('create', 'modify', 'debug', 'review', 'package' a plugin) plus a concrete manifest filename ('plugin.toml'). Not 5 because common synonyms like 'N.E.K.O plugin development', 'add a plugin', or 'extension'/'adapter' variations users might say are absent.

Distinctiveness Conflict Risk

Clear niche ('N.E.K.O plugins') with triggers anchored to plugin-specific artifacts (plugin.toml, plugin SDK, plugin CLI), making mis-triggering against unrelated skills very unlikely. Not 4 because no meaningful overlap risk with closely related skills exists — the domain term is unique.
