form

form is a skill for Claude Code from IamK77/Skill. It costs 34 tokens per session (564 once invoked), scanned A, original, Apache-2.0.

A frontend design guide for deciding how surfaces feel three-dimensional through shadows, highlights, gradients, corners, and texture. Frontend means the part of a website or app that people see and use.

In plain words
What is it for?
Use it after choosing color tokens to define elevation, corner-radius, lighting direction, gradients, texture, and the visual treatment of interface surfaces.
Why use it?
It replaces disconnected visual tweaks with a shared depth and shape system, so interface elements look like they belong together.

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

form 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 27d 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

form

Explore shape, depth, light, texture, and material metaphors for an interface. Use to generate visual form, not to enforce universal radius or shadow formulas.

Starting point

Form suggests how an interface can be touched, layered, or inhabited—even when it is only pixels. A material metaphor is useful when it creates relationships, not when it adds realistic decoration everywhere.

Bring a question, fragment, reference, or tension. Follow whichever association becomes useful; these invitations are not a sequence to complete. Speculation should remain distinguishable from an observed fact.

Thought experiments

Change the imagined material

Render the same interaction as folded paper, machined metal, ink, or frosted glass. Transfer one property such as layering, precision, absorption, or diffusion.

Flatten, then exaggerate

Imagine no depth at all, then an exaggerated relief. Find which distinction actually needs depth and which is better carried by spacing or colour.

Give the light a story

Try direct illumination, ambient haze, or backlit marks. Explore how light could organise hierarchy without requiring literal physical simulation.

A possible turn

A nested panel could be an inset tray, a stack of sheets, or simply a typographic section. Each implies different edges and shadows. Choosing “no object here” may be the most expressive form decision.

Leave the space open

Offer a few genuinely different possibilities, a sketch, an analogy, or a sharper question when useful. Do not turn every prompt into a scored diagnostic, a completion gate, or a demand for an action plan. The human may choose a direction, combine them, or leave the question open.

If the direction becomes a component family, systems can name and implement its tokens. Optical exceptions are allowed; references are techniques, not universal laws.

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

form is a skill published in the GitHub repository IamK77/Skill (2 stars, last pushed 5d ago), licensed Apache-2.0. It adds 34 tokens to every session and 564 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
