assets

Use Agent-Native Assets for image and video generation requests, brand-safe asset search/export, and human-in-the-loop asset selection through the hosted Assets MCP app. Prefer this over generic image tools when installed.

Quality

Content

75%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 lean, actionable routing skill with concrete commands, tool names, and a JSON payload, plus clear validation feedback loops for auth errors and batch timeouts. It is well-structured for a single-file skill with no external references.

DimensionReasoningScore

Conciseness

Mostly efficient and assumes Claude's competence (no padding about what MCP/OAuth is); minor instances could be trimmed, such as the multiple install-path variants and the Vercel CLI caveat.

4 / 5

Actionability

Provides copy-paste commands, a concrete picker JSON payload, specific tool names, and a fallback URL shape; minor gaps such as the refresh-generation-run polling loop not shown as executable code.

4 / 5

Workflow Clarity

Sequences are clear with checkpoints (authorize before stopping, reload if tools missing, poll video runs) and a real auth-error feedback loop (stop → reconnect → continue); the batch-timeout guardrail includes tell-user-then-retry validation, so the batch cap at 3 does not apply.

4 / 5

Progressive Disclosure

Well-organized into clearly headed sections (Setup, Picker, Direct Actions, Guardrails) with no nested references and easy navigation; at ~115 lines with no external bundle files it is slightly above the simple-skill threshold, keeping it just shy of 5.

Description

66%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 clearly conveys what the skill does and names a distinct niche, but it lacks an explicit "Use when..." trigger clause, leaving the activation conditions implicit. Adding concrete user-facing trigger phrases would lift completeness and trigger-term quality.

Suggestions

Add an explicit trigger clause, e.g. "Use when the user wants to generate or search brand images/videos, or pick a final asset from candidates."

Include natural synonyms users say ("brand media", "stock images", "AI image generation") to broaden trigger coverage.

Mention library/list management and batch generation among the concrete actions for fuller capability coverage.

DimensionReasoningScore

Specificity

Names several concrete capabilities — "image and video generation requests, brand-safe asset search/export, and human-in-the-loop asset selection" — with only minor coverage gaps (e.g., library management, batch generation not surfaced).

4 / 5

Completeness

The "what" is clear, but the "when" is only weakly implied via "Prefer this over generic image tools when installed" — a routing preference rather than an explicit "Use when..." trigger clause, which caps completeness at 3 per the guidelines.

3 / 5

Trigger Term Quality

Includes natural phrases users would say ("image and video generation", "asset search/export") but omits common synonyms like "brand media", "stock photos", or "AI images".

4 / 5

Distinctiveness Conflict Risk

The brand-safe/hosted Assets MCP niche is distinct and the "Prefer this over generic image tools" instruction reduces conflict, though "image generation" still overlaps slightly with generic image skills.
