molyanov-ai-dev: Skill for Codex

.codex/skills/layout-writing/SKILL.md

layout-writing is a skill for Codex from pavel-molyanov/molyanov-ai-dev. It costs 131 tokens per session (1,192 once invoked), scanned A, original, MIT.

A layout implementation guide for matching web pages to Figma designs, exported designs, screenshots, or an existing project style. It also covers responsive layouts that adapt to different screen widths.

In plain words
What is it for?
Use it to build or adjust web layouts, reproduce designs, move sections from design exports into a project, and make pages responsive.
Why use it?
It reduces guesswork when turning a visual reference into working page code. It helps keep proportions and visual details consistent while limiting changes to the requested area.

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

layout-writing 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 11d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/capture.mjs, scripts/capture.test.mjs, scripts/overlay.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Layout Writing

Deliver a layout that matches its exact source where one exists, fills only genuinely unspecified decisions from project evidence, and works at relevant widths in the existing codebase.

Scope and Source

  1. Read repository guidance, the affected component and styles, tokens, fonts, images, nearby components, and the relevant run or build command.
  2. Classify the scope:
    • selected area — verify the changed element, component, or section with its nearest context;
    • whole page — build an ordered inventory of every major visual block from source metadata, node IDs, a DOM outline, or complete source-image segments, then verify every item.
  3. With an exact source, apply reproduce.md — source acquisition, native-size evidence, and comparison. Without an exact source, apply design-decisions.md — project-first decisions for unspecified values. For a partial source, apply each reference only to the area it governs.
  4. Ask only for blockers that project or source evidence cannot resolve: the relevant frame when a Figma link names only a file, substitution of a required missing font or asset, or expansion beyond the requested scope.

Treat a new requirement, state, edge case, or improvement discovered during implementation or review as a proposal, not authorization. If it changes the agreed presentation, behavior, scope, approach, or material complexity, explain it and get the user's decision first. Correct autonomously only a local mismatch in agreed normal presentation. Treat a rare or source-undefined viewport, content state, or interaction state as a user decision even when its correction looks local.

layout-writing owns markup structure, styles, responsive behavior, typography, asset placement, and visual verification. code-writing owns data flow, state, APIs, validation, and business behavior; use both for mixed work.

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.
