Conciseness

The body is deliberately lean ('intentionally lean: load only the reference files that match'), assumes Claude's competence, and contains no concept-explanation filler, so every token earns its place.

Actionability

Provides concrete executable guidance including a file-load command, exact env vars and flags (--host, --port, WEB_UI_HOST, WEB_UI_PORT), runtime paths (/opt/venv-a0, /opt/venv, /a0/), and named sibling skills for handoffs.

Workflow Clarity

The numbered 'Working Flow' sequences classification through verification, and step 7 names explicit validation checks (frontmatter parsing, reference paths, markdown sanity), giving a clear sequence with a validation checkpoint.

Progressive Disclosure

The body is an overview with a clear need-to-reference table; all seven referenced files exist and are one level deep, and handoffs to sibling skills are explicitly named, making navigation easy.

Specificity

Lists multiple concrete surfaces ('framework architecture, tools, extensions, API/WebUI handlers, agent profiles, prompts, skills, projects, runtime boundaries, and contribution workflow') rather than vague language, matching the anchor for listing several specific actions.

Completeness

States both what it does ('Development guide for extending Agent Zero from current source and DOX') and when to use it via an explicit 'Use for ...' clause, which satisfies the explicit-trigger guidance that prevents a cap at 2.

Trigger Term Quality

Natural terms users would say ('framework architecture', 'tools', 'extensions', 'API/WebUI handlers', 'agent profiles', 'prompts', 'skills', 'projects') are well covered alongside the framework name, matching the good-coverage anchor.

Distinctiveness Conflict Risk

Scoped tightly to Agent Zero framework development with niche-specific triggers, making it unlikely to fire for an unrelated skill; matches the clear-niche anchor.
