What it does

Wireframe Annotated is an agent skill from nexu-io/open-design. An annotated / redline lo-fi wireframe — a desktop landing/marketing page drawn as flat greyboxes inside a browser chrome frame, overlaid with numbered annotation pins (①②③④⑤) in a single accent color, paired with a right-hand SPEC PANEL that lists each numbered pin with a short engineering / UX note. This is the "wireframe + redline spec" style — clean, flat, low-fidelity, NOT hand-drawn. Use when the brief asks for "annotated wireframe", "redline wireframe", "wireframe with spec", "lo-fi landing wireframe"…

Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.

It sits in Frontend & Design, covering UI design. The repository describes itself as: 🎨 Best DeepSeek Harness Design Plugin. The open-source Claude Design alternative. 🖥️ Local-first desktop app. 🖼️ Your coding agent becomes the design engine: prototypes… The licence is Apache-2.0.

When your agent uses it

  • The brief asks for annotated wireframe
  • Redline wireframe
  • Wireframe with spec
  • Lo-fi landing wireframe

Example prompts

  • “wireframe + redline spec”
  • “annotated wireframe”
  • “redline wireframe”
  • “/wireframe-annotated”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Skip finished UI. This skill explicitly wants a low-fidelity greybox
  2. Set the two-column shell. LEFT is the wireframe canvas: a browser-chrome
  3. Lay out the canvas, top to bottom, each block a greybox with a numbered
  4. Mirror every pin in the spec panel. Each spec row = the circled number in
  5. Self-check

What it can do on your machine

Read from SKILL.md and the folder at commit 3449fa6. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Wireframe Annotated loads about 960 tokens when it runs. Until then it costs about 145 tokens; SKILL.md has 380 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~145
When it runs · the whole SKILL.md, loaded when a task matches
~960

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Wireframe Annotated Skill

Produce a single flat, low-fidelity landing-page wireframe with a redline spec. The whole point is "structure + handoff notes, not pixels" — greyboxes carry the layout, numbered pins call out regions, and a right-hand spec panel turns each pin into a short engineering / UX note. Keep it clean and flat; never hand-drawn or scribbly.

Workflow

  1. Skip finished UI. This skill explicitly wants a low-fidelity greybox look. Honor type tokens only loosely (one clean sans like Inter / system-ui for labels, one mono like IBM Plex Mono for the spec notes and pin numbers). Use medium-grey fills with defined darker borders so the page reads as a thumbnail — avoid near-white-on-white, which renders blank.

  2. Set the two-column shell. LEFT is the wireframe canvas: a browser-chrome framed greybox page. RIGHT is a narrow "ANNOTATIONS / SPEC" panel. Pick ONE accent color (coral or blue) and use it ONLY for the numbered pins and the matching spec numbers — everything else stays greyscale.

  3. Lay out the canvas, top to bottom, each block a greybox with a numbered pin absolutely positioned on it:

    • Top nav — logo greybox + nav lorem-bars + a primary button block. Pin ①.
    • Hero — big headline lorem bars + subhead + two CTA button blocks on the left; a large image placeholder (rect with a diagonal X) on the right. Pin ②.
    • Logo strip — a row of 5 small greybox partner logos. Pin ③.
    • Feature grid — 3 cards, each an icon square + title bar + 2 text bars. Pin ④.
    • Footer — columns of lorem link-bars. Pin ⑤.
  4. Mirror every pin in the spec panel. Each spec row = the circled number in the accent color + a short mono/sans note, e.g. "① Sticky nav, 64px, condenses on scroll", "② Hero H1 48/56, CTA pair primary+ghost", "③ 5 partner logos, greyscale", "④ 3-up at ≥960px → 1-up mobile", "⑤ 4-col footer, legal row". Mark the panel and each row with data-od-id.

  5. Self-check:

    • Every numbered pin on the canvas has exactly one matching spec row.
    • The accent color appears ONLY on pins + spec numbers; the rest is greyscale.
    • The page should read clearly at thumbnail size; if blocks vanish into the background, darken the fills/borders.
    • It must NOT look pixel-perfect or hand-drawn — flat greyboxes only.
