Tier-2 Review: wireframe-annotated (Cluster: general)

Composite score (as listed): 4.3 / 5.0

---

What we attempted

We pulled the skill’s SKILL.md and ran it through the standard harness (D-048) with two checks: install and smoke-invocation. The goal was to verify whether the skill could be installed and invoked as described, and whether a minimal run produced the expected annotated wireframe output.

What failed

Both checks were skipped, not failed outright, but the result is functionally equivalent to a hard failure for practical use:

• install (skipped): SKILL.md contains no install command, no package manager reference, no file manifest, and no setup routine. It reads as a design-template description, not a tool or agent skill with a defined installation path.
• smoke-invocation (skipped): No executable, CLI entrypoint, or invocation pattern is described. The document only describes a visual style (flat greyboxes, numbered pins, spec panel) and lists trigger phrases like “annotated wireframe” or “redline.” There is no way to invoke the skill programmatically or through an agent runtime.

Key blocker (from harness): SKILL.md is a design template description with no install or invocation instructions.
Observed dependencies: none.

What we observed

The SKILL.md content is a concise, well-written style guide for producing a lo-fi annotated wireframe. It specifies:

• Format: flat greyboxes inside a browser chrome frame
• Annotation: numbered pins (①②③④⑤) in a single accent color
• Companion element: a right-hand SPEC PANEL mapping each pin to an engineering/UX note
• Explicit “NOT hand-drawn” and “clean, flat, low-fidelity” constraints
• Trigger phrases in English and Chinese (线框图, 标注线框, redline)

As a design system fragment, this is clear and usable by a human designer. As a skill in the agentic sense, it is incomplete: there is no prompt template, no tool call, no output schema, no example conversation, and no way for an agent to know how to produce the wireframe (e.g., via SVG generation, HTML/CSS, or a drawing library). The skill describes the what but not the how.

Honest rating caveat

Because the harness could not exercise the skill, the listed composite score of 4.3 is theoretical. The dimension scores (D1–D5) appear to reflect the quality of the description rather than the operability of the skill. Until a physical re-run succeeds — meaning an install path is added and a smoke test produces an annotated wireframe — the score should not be treated as verified. In practice, a skill that cannot be installed or invoked should likely score lower on D4 (self-containment) and D5 (reusability) than the listed 4.0 and 3.5.

Is it still valuable in principle?

Yes, in principle. The idea behind this skill is sound: many product and design briefs ask for annotated wireframes, and a template that standardizes the output style (greyboxes, pins, spec panel) would save time and reduce ambiguity. The trigger-phrase coverage is thoughtful, including bilingual cues.

However, value is contingent on two additions:

1. A concrete output mechanism — e.g., “generate an SVG using this template” or “render HTML/CSS with the following structure.”
2. An invocation contract — either a CLI command, an agent tool definition, or a self-contained prompt that an LLM can follow without external context.

Without those, the skill is a reference card, not a skill. We recommend the creator either convert it into a tool-backed skill or explicitly scope it as a “style guide” rather than an executable skill. The underlying design pattern is useful, but the packaging currently prevents anyone from using it in an automated workflow.

Tests simulated against README claims; pending physical re-run in Docker harness. Ran 2026-08-14.

Overall: broken. 0 tests passed, 0 partial, 2 skipped; key blocker: SKILL.md is a design template description with no install or invocation instructions.

Test	Status	Notes
install	skipped	SKILL.md does not document an install command; it is a design template description, not a CLI tool.
smoke-invocation	skipped	No README or executable invocation described; SKILL.md only describes a visual template style.
