Conciseness

The ~25-line body is lean with every sentence earning its place: a one-line definition of the niche framework, the docs path, and install fallback. It explains nothing Claude already knows and adds no padding, matching the anchor-5 'every token earns its place' profile; anchor 4 would require trimmable over-explanation, which is absent.

Actionability

Concrete, copy-paste-ready pointers and commands are present: `node_modules/eve/docs/README.md`, `npm install eve`, `npx eve init <agent-name>`, with clear branch logic for the not-installed case. It falls short of anchor 5 because the skill itself gives no worked example or direct guidance for any actual eve task — it delegates everything to the package docs, leaving minor gaps if the docs path differs or the package layout changes.

Workflow Clarity

This is a simple single-purpose skill (under 50 lines, one task: consult the version-matched bundled docs) whose single action is unambiguous — a clear starting file (docs/README.md with 'the full index and recommended reading order'), an explicit ordering rule ('Before writing any eve code, read the relevant guide there first'), and a handled fallback branch. The rubric's simple-skill exception applies; no destructive or batch operations exist to require validation checkpoints.

Progressive Disclosure

The body is a well-organized overview that keeps all detail in the package's own docs via a single clearly-signaled, one-level-deep reference (node_modules/eve/docs/README.md), which is the ideal progressive-disclosure pattern. Per the rubric's under-50-lines guideline, the clean two-section structure with no unnecessary inline content earns 5; anchor 4 would require organization gaps that are not present.

Specificity

Quotes several concrete actions ("creating, editing, or debugging an eve project") and a comprehensive coverage list ("durable sessions, tools, skills, connections, channels, sandboxes, subagents, schedules, evals, frontend clients, and Agent Runs observability"). The core 'what' remains the generic word 'guidance' rather than verb-level concrete actions like the anchor-5 examples, so it sits between anchor 3 and 5 — minor gaps in coverage phrasing keep it at 4.

Completeness

Explicitly answers both what ("eve framework guidance for durable AI agents and agent-powered applications... Covers...") and when ("Use when creating, editing, or debugging an eve project, when the user explicitly asks for eve, or when the build-agents skill has selected eve as the default framework") with concrete trigger phrases, plus an explicit when-not clause. This matches the anchor-5 example structure exactly.

Trigger Term Quality

Good natural keyword coverage: "eve project", "eve framework", "eve agent", "Agent Runs observability", "frontend clients", "durable sessions" — phrases a user would naturally say. A few natural variations users might type (e.g. "npx eve", "vercel agent-runs", "eve.dev") are absent from the description itself, so it fits anchor 4 rather than the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

The distinctive framework name 'eve' plus explicit exclusions ("Do not use for incidental agent mentions, generic agent-building prompts, or established non-eve stacks unless the user asks for comparison or migration") give it a clear niche with minimal conflict risk, matching anchor 5.
