molyanov-ai-dev: Skill for Codex

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

layout-reviewing is a skill for Codex from pavel-molyanov/molyanov-ai-dev. It costs 72 tokens per session (581 once invoked), scanned A, original, MIT.

A review guide for checking whether a web layout matches its source, works at different screen sizes, and follows project standards.

In plain words
What is it for?
Use it to review implemented pages, compare them with screenshots or source designs, and check required widths and interface states.
Why use it?
It helps find visual and responsive problems without changing intentional design choices.

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-reviewing 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 12d 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.

Layout Reviewing

Judge the supplied implementation and prepared evidence. Do not redesign the interface or replace an intentional source value with personal taste.

Review Basis

  • Where an exact source exists, it controls defined geometry, spacing, color, typography, crop, effects, layering, content placement, and responsive states.
  • Where no source exists, use repository rules, the same component in other states, neighboring UI, tokens, and established components as the review standard.
  • For a partial source, keep these responsibilities separate. General design conventions do not override values the source defines intentionally.

Evidence Coverage

  • A selected-area review covers the changed block, its nearest positioning context, applicable states, and every required width.
  • A whole-page review requires an ordered source- or DOM-derived inventory and evidence for every listed block at every required width.
  • Required widths include baseline 360, 430, 768, and 1440 coverage, established source or user-screenshot viewports, and both sides of affected breakpoints.
  • Missing evidence is a defect only when the review contract requires it and its absence prevents a defined block, state, or width from being checked. Identify that missing coverage precisely.

Visual Criteria

Inspect each supplied width, block, and state for:

  • alignment, container bounds, spacing, density, sizing, and responsive reflow;
  • font family, weight, size, line height, wrapping, truncation, and text clipping;
  • colors, opacity, borders, radii, shadows, backgrounds, and layer order;
  • image or icon choice, aspect ratio, crop, position, and asset quality;
  • horizontal overflow, unusable compression, disappearing content, and broken interaction states;
  • consistency with project components and tokens where the source leaves a decision unspecified.

For exact-source comparisons, source and site blocks must have matching native dimensions. A diff image localizes pixel differences but does not prove a defect by itself. Attribute residual text differences to rasterization only after typography, wrapping, baselines, and bounds align.

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.
