Implement Figma design in code

Turn visible Figma evidence into the smallest project-native implementation that preserves the intended result. Keep that result focal: project files, TemPad output, rules, and tool calls are evidence for the implementation, not deliverables to reproduce mechanically.

Require TemPad Dev MCP to provide trustworthy design evidence for the current selection or exact node IDs inside the user's established scope. Never reconstruct the design from memory, screenshots alone, or get_structure metadata.

Evidence and authority

Use each source only for what it can establish:

• The user sets scope, requirements, prohibitions, and missing product or implementation decisions.
• The project sets framework, file placement, component boundaries, styling, tokens, assets, dependencies, and verification conventions.
• TemPad Dev sets visible structure and rendered design facts.

Follow project instruction files for concerns outside Figma-to-code translation. Do not add policy for routing, analytics, i18n, CMS, or other orthogonal systems.

TemPad can establish visible hierarchy, layout, spacing, typography, color, effects, token references, exported assets, and codegen unit context. It cannot establish unevidenced states, responsive behavior, business logic, navigation, validation, analytics, or project conventions. Treat get_structure as hierarchy and geometry evidence only, never as missing style truth.

Workflow

1. Establish the implementation envelope

Read only local evidence that can change this implementation, in this order:

1. applicable AGENTS.md or equivalent instructions;
2. relevant design-system, token, component, and asset guidance;
3. the nearest comparable implementation and reusable primitives;
4. framework, styling, and check configuration needed for this task.

Determine the target file or component boundary, framework, styling method, token and asset paths, reuse candidates, dependency constraints, and narrowest relevant checks. Inspect Tailwind version and theme scales only when the project actually uses Tailwind-compatible tooling.

Do not inventory the repository broadly after the needed envelope is clear. If a missing project decision would materially change the result, ask before implementation.

2. Read the design at the requested scope

Call TemPad Dev's get_code directly for the requested roots before implementing:

• omit nodeId and nodeIds for the current selection, including multiple nodes; use nodeId for one exact target or nodeIds for several. Use only IDs supplied by the user or returned by TemPad inside the established scope;
• default to resolveTokens: false. Use true when literal output is requested or a targeted read is needed to establish a consumer's actual value;
• set preferredLang from the project target; treat returned lang as authoritative because plugin configuration may override that preference;
• keep TemPad's default vector behavior unless the user explicitly requests asset-preserving vector fidelity; for that request, use vectorMode: "snapshot" when the active tool schema supports it.

Keep each root's code, lang, warnings, assets, tokens, and codegen together. In a batch, each results entry identifies its nodeId and carries either a result payload or an error. Use that root's codegen.config.{cssUnit,rootFontSize,scale} for exact unit conversion.

Preserve the requested composition within each root. Load only the guidance relevant to the returned evidence:

• Assets for asset delivery;
• Tokens for token definitions, references in code, or consumer values needed for a mapping decision;
• Recovery for remainingNodeIds, errors, warnings, wrong-file reads, or incomplete evidence.

3. Separate facts, adaptations, and gaps

Before editing, distinguish:

• design facts to preserve;
• project-native adaptations supported by existing components, tokens, utilities, or asset conventions;
• unevidenced product decisions that must remain unimplemented or be asked.

Map by rendered value and semantics, not by a convenient name. A familiar component or token is a candidate, not proof of equivalence. If more than one material implementation path remains equally plausible, ask the user. Infer only low-consequence details and report any inference that affects the result.

4. Implement the smallest coherent change

• Keep the established framework, styling system, file placement, imports, and abstraction level. Do not introduce a parallel system.
• Reuse an existing primitive only when its semantics and rendered behavior fit without guessing. Do not force reuse that erases design facts.
• Preserve exact rendered values unless project evidence proves an equivalent token, utility, or component. For rem output, convert with TemPad's actual cssUnit, rootFontSize, and scale.
• Preserve intentional uncommon output, including pseudo-elements, filters, masks, blend and backdrop effects, gradients, and non-default compositing, unless a documented project constraint requires an adaptation.
• Implement only evidenced states and responsiveness. Do not invent hover, loading, error, empty, disabled, or responsive behavior.
• Use native semantic elements and preserve keyboard access and accessible names when an established primitive does not already provide them.
• Add no runtime or build dependency without user approval unless the user has explicitly waived that constraint.
• Keep data-hint-* attributes out of shipped code.

Do not enter a visual tuning loop. Change the implementation again only when new project, design, tool, or verification evidence identifies a concrete defect.

5. Verify in the project's real workflow

Run the narrowest relevant checks defined by project instructions and scripts. Repair implementation failures and rerun the affected checks. Use an existing preview, screenshot, or comparison workflow when available; do not invent a universal verification matrix.

If no runnable check exists, report the implementation as unverified. Do not claim visual completion without a real project comparison path; ask the user to confirm the rendered result against Figma.

Hard stops

Pause the affected work and anything that depends on it when:

• TemPad is unavailable, unauthorized, inactive on the intended file, or cannot provide trustworthy evidence for a required composition;
• the target is unreadable or not visible;
• project, design, and user evidence still conflict after targeted recovery;
• a missing decision would materially change behavior, structure, dependency, asset delivery, or token mapping;
• required assets cannot be retrieved or stored under project policy.

Continue independent work supported by sufficient evidence. Report any requested scope left incomplete and the concrete action needed to unblock it.

Handoff

Report:

• what changed and where;
• only the relevant adaptation, inference, warning, asset/token handling, or residual visual risk;
• checks run, their result, and what remains unverified.

Keep absent concerns absent from the handoff. Do not produce a compliance checklist for branches the task never used.

Decision example

If TemPad emits padding: 15px and the project has a space-4 token worth 16px, preserve 15px unless project evidence explicitly makes the token the intended mapping. Project consistency selects the representation; it does not authorize changing the visible design.
