Conciseness

The body is mostly lean: terse 'Rules:' bullets and copyable code with minimal tutorial prose, and it explicitly tells the model not to write prose. It is not a 5 because dense sections (e.g., the long Structured Outputs rules list) carry detail that borders on over-explanation and could be trimmed.

Actionability

Most sections give executable, copy-paste TypeScript (canonical pattern, forward(), streamingForward(), validation). It is not a 5 because several examples contain out-of-scope placeholders (e.g., `topic` in addAssert, `bestIndex` in resultPicker, `tools` in function calling) that prevent them from running verbatim.

Workflow Clarity

The guidance is well sequenced (defaults -> canonical pattern -> per-feature sections -> 'Do Not Generate' guardrails) and the single codegen action is unambiguous. It is not a 5 because there is no explicit verify/validation checkpoint (e.g., 'confirm the generated code type-checks'), though the destructive/batch cap does not apply to this codegen skill.

Progressive Disclosure

Clear section headers organize the content and the external example links are clearly signaled one level deep. No bundle files exist (references/scripts/assets absent), and some inline detail (full chat-log type definitions, deep structured-output modes) could be split into reference files, keeping this just below score 5.

Specificity

The description names the domain ('generate correct AxGen code using @ax-llm/ax') with one concrete action, but does not enumerate multiple distinct actions — the long list that follows is trigger terms, not capabilities. It sits above score 2 (which only names the domain) but below score 4 (which lists several specific actions).

Completeness

It explicitly states what the skill does ('helps an LLM generate correct AxGen code using @ax-llm/ax') and provides an explicit 'Use when the user asks about...' clause with concrete trigger phrases. This matches the score-5 anchor that requires both what and when with concrete triggers.

Trigger Term Quality

Broad, relevant coverage of API-level terms users would say ('ax(), AxGen, generators, forward(), streamingForward(), validation, assertions, streaming assertions, field processors, step hooks, self-tuning, structured outputs') plus MCP boundary terms. Not a 5 because the terms skew toward library jargon rather than natural synonyms/file extensions a lay user would say.

Distinctiveness Conflict Risk

It carves a clear niche (AxGen codegen) and explicitly de-conflicts with a sibling skill ('For MCP clients, transports, prompts, resources, tasks, subscriptions, or authentication use ax-mcp alongside this skill'), minimizing wrong-skill triggering. Matches the clear-niche, minimal-conflict anchor.
