Development guide for extending Agent Zero from current source and DOX. Use for framework architecture, tools, extensions, API/WebUI handlers, agent profiles, prompts, skills, projects, runtime boundaries, and contribution workflow. Load the focused reference files before giving implementation guidance.

Quality

Content

86%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.

The body is a well-structured, lean development router that defers detail to seven real reference files via a clear need-to-file table. It is highly actionable with explicit grounding and verification steps; the only gaps are minor verbosity and the absence of an explicit error-retry feedback loop.

Suggestions

Add an explicit validate->fix->retry feedback loop in the Working Flow (e.g., 'if DOX checks fail, fix and re-run before proceeding') to strengthen error recovery.

Tighten the longer Reality Rules (e.g., rule 6 on /a0/ runtime root) by splitting each into a one-line rule plus a brief example, trimming redundant phrasing.

Consider adding a one-line 'when to skip loading references' note so simple lookups don't force unnecessary reference loads.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence, focusing on non-obvious gotchas (runtime splits, path boundaries, port discovery) rather than concepts Claude already knows; a few rules are slightly verbose and could be tightened.

4 / 5

Actionability

Provides concrete, executable guidance including a copy-paste tool invocation for loading references, specific env vars (WEB_UI_HOST/WEB_UI_PORT), and a need-to-file reference table that maps directly to verified bundle files.

5 / 5

Workflow Clarity

The 7-step Working Flow is clearly sequenced with grounding/validation steps (inspect source before patching, run DOX checks, verify frontmatter/paths/markdown) and a Closeout reporting loop, but lacks an explicit validate-fix-retry feedback loop.

4 / 5

Progressive Disclosure

SKILL.md is a concise overview with a clearly signaled one-level-deep Reference Map table; all seven referenced files exist in ./references/ and content is appropriately split for easy navigation.

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.

The description is well-scoped to an Agent Zero development niche, clearly answering both what the skill does and when to use it with an explicit trigger clause. It is comprehensive in capability coverage, with only minor room for more action-oriented verb phrasing and additional trigger synonyms.

DimensionReasoningScore

Specificity

Lists a broad set of concrete capability areas ("framework architecture, tools, extensions, API/WebUI handlers, agent profiles, prompts, skills, projects, runtime boundaries, and contribution workflow") but these are domain nouns rather than concrete verb-driven actions, leaving minor gaps versus a fully comprehensive action list.

4 / 5

Completeness

Explicitly answers both what ("Development guide for extending Agent Zero from current source and DOX") and when ("Use for framework architecture, tools, extensions...") with concrete trigger phrases via the explicit "Use for" clause.

5 / 5

Trigger Term Quality

Good natural keyword coverage for an Agent Zero developer ("extend", "framework architecture", "tools", "extensions", "API/WebUI", "agent profiles", "prompts", "skills", "projects"), though a few natural synonyms or phrasings a user might say are missing.

4 / 5

Distinctiveness Conflict Risk

Scoped tightly to extending Agent Zero with framework-specific triggers, giving it a clear niche and minimal overlap risk with generic development skills.
