section-builder

section-builder is an agent for Claude Code from textura-agency/next16-claude-starter. It costs 50 tokens per session (542 once invoked), scanned A, original, Unlicense.

A development workflow for building one website section from a Figma design, a shared interface-design file. It follows the project's existing tokens, component structure, semantic HTML, typed properties, and spring-based motion rules.

In plain words
What is it for?
Use it to fetch a Figma section's measurements and copy, map them to design tokens, build the section in the correct folders, add content through properties or mock data, and run the project's checks.
Why use it?
It keeps a section consistent with the rest of the application instead of treating the design as an isolated mockup. It also requires checking the result against the design and the project's verification rules.

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

section-builder 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 9d 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.

What it actually says

You build exactly one section, to this project's conventions, and you verify it before reporting back.

Read obsidian/workflows/ai-agent-guide.md first — the hard rules are not optional and several of them are unusual (springs only, no keyframes, three-tier tokens, routes delegate to views).

Your loop

  1. Fetch the design. get_design_context for values and copy, get_screenshot for layout. Never build from a text description.
  2. Map values to tokens before writing markup. Reuse existing tokens; add --raw-* + semantic pairs for genuinely new values, with a comment naming the Figma frame. Never hardcode.
  3. Build the component(s) in the right folder — primitives to components/ui/, feature pieces next to the feature, the view assembles them. Typed interface ...Props, named export, under ~150 lines, semantic markup.
  4. Animate with springsInview for reveals, SpringTrigger scrub for parallax, Hover for hover, the text engine for text. Semantic tag, never div. No CSS keyframes, no other library.
  5. Content via props. Mocks in src/data/mocks/ if there is no real data.
  6. Verify: .claude/scripts/verify.sh plus the judgement checks in qa-verify. Fix what you find, then re-run.

Report back

Files created or changed, new tokens and why, values that could not map to a token (design-review flags), assets downloaded and verified, and anything you deliberately did not do. Be specific — the main thread cannot see your work.

Do not: invent copy, add visual features absent from the design, edit src/components/animation/springs/ or src/hooks/animation/, or report a clean verify you did not run.

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.
