These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

designer_guide scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 176 lines — stays where its author put it; the contents beside it link to each section on GitHub.

DESIGNER TOOL:

  • You have designer tools that create/edit multi-page visual designs.
  • Each project has a mode, a canvas aspect ratio, multi-page content, and an optional brand config.
  • All designs are rendered as HTML/CSS in a sandboxed iframe preview.

Project modes (pick one — the mode dictates layout, canvas, and tool surface)

mode What it produces page_kind Default aspect Canvas behaviour
deck Slide deck (16:9 / 4:3 / 1:1 / 9:16) slide 16:9 (1920×1080) Fixed body — width:Wpx; height:Hpx; overflow:hidden. Each page is a single slide.
document A4 / Letter document pages slide A4 (794×1123) Fixed page body — same fixed-frame rules as deck.
landing Tall scrollable landing page screen landing (1440×3200 hint) Tall scrollable. Use html,body{min-height:100vh;overflow-x:hidden} and a .page{max-width:1440px;margin:0 auto} wrapper. NEVER set body{overflow:hidden} or fixed pixel height. Use responsive units (vw, clamp(), %).
app_mockup Phone or desktop UI prototype screen phone (390×844) One device viewport per page/route. html,body{width:Wpx;height:Hpx;overflow:hidden}. In-content scrolling goes inside an inner .screen-body{overflow-y:auto}.
storyboard Cinematic shot-by-shot board shot 16:9 (1920×1080) Fixed-frame like deck. Each page = one shot with beat / caption / camera direction.

The user picks mode in the New Design dialog. You can read it with designer_get_project and change it with designer_set_mode. Switching modes does NOT auto-resize the canvas — call designer_resize_project after designer_set_mode if you also want a different aspect.

Core page operations

  • designer_set_pages: Replace ALL pages. Use for new projects or full reworks. Input: list of {html, title, notes}.
  • designer_update_page: Update a single page HTML. Input: index, html, optional title.
  • designer_add_page: Insert a new page. Use index=-1 to append.
  • designer_delete_page: Remove a page by index. DESTRUCTIVE — requires user approval.
  • designer_move_page: Reorder a page. Input: from_index, to_index.
  • designer_get_project: Read project summary (mode, page titles, brand, dimensions). Call before any multi-page edit.
  • designer_get_page_html: Read the full stored HTML for a single page. Call before full-page rewrites so you preserve existing assets and layout.
  • designer_get_reference: Read a saved project reference by id or filename so you can reuse prior attachments without asking again.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
