# Figma Best Practices > Author, review, or repair Figma files, component libraries, variables, handoff surfaces, and source-backed app/Figma fidelity audits using prompt-first file-craft doctrine. Use for Figma organization, components, tokens, Dev Mode/Code Connect/Make/MCP readiness, duplicate/stale cleanup, screenshot/reference handling, and app/source parity evidence. Do not use for generic visual taste critique, implementing frontend code from Figma, operating the Figma UI/tool itself, or deterministic visual-diff automation. - Skill: `aelaguiz/figma-best-practices` (Agent Skill, multi-file: 7 files) - Install (CLI): `npx skillmds@latest add aelaguiz/figma-best-practices` - Raw SKILL.md: https://api.skillmd.com/api/skills/aelaguiz/figma-best-practices/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Design & Media - Author: aelaguiz (https://skillmd.com/u/aelaguiz) - Updated: 2026-09-10 - Page: https://skillmd.com/skills/aelaguiz/figma-best-practices --- # Figma Best Practices Use this skill when the work is Figma file craft: creating, reviewing, or repairing Figma structures so they are readable by designers, developers, Dev Mode, Code Connect, Figma Make, Sites, Buzz, Slides, and MCP-fed coding agents. Use the same skill when the user asks whether Figma accurately reflects an app, source component, token system, asset set, screenshot, or runtime state. Treat that as source-backed review work inside this skill, not as a separate mode, runner, or app-fidelity skill. This is a prompt-only skill. It ships no scripts, runners, controllers, Figma API wrappers, browser automation, OCR stacks, fuzzy matchers, or visual-diff harnesses. ## When to use - The user wants a Figma design-system plan, file structure, component model, variable/token architecture, library split, or publishing workflow. - The user wants a Figma file, page, component set, screenshot board, evidence board, or Dev Mode surface audited for structural quality. - The user wants source-backed app/Figma fidelity review: target classification, app/source matching, screenshot/reference handling, duplicate/stale analysis, visual parity evidence, or repair planning. - The user wants guidance on Auto Layout, Grid Auto Layout, constraints, variables, modes, styles, components, variants, slots, Code Connect, annotations, Dev Resources, or AI/MCP readiness. - The user gives an incomplete Figma URL, node, screenshot, source hint, vague complaint, or broad cleanup request and needs grounded judgment about what is knowable. ## When not to use - The task is implementing frontend code from a Figma design. Use the relevant coding or Figma-implementation workflow instead. - The task is operating the Figma UI, clicking through a file, or automating the Figma app itself. Use the appropriate browser, Figma, or MCP tool skill. - The task is generic visual taste critique without any Figma file-structure, system, token, handoff, parity, or downstream-consumer concern. - The user needs deterministic visual-diff automation, OCR, parser stacks, or a Figma MCP wrapper. This skill can describe evidence expectations, but it does not provide tooling. - The user needs the latest post-source Figma release facts. Verify current official docs or release notes before relying on changing limits or feature availability. ## Non-negotiables - Treat a high-quality Figma file as a self-describing artifact, not a static picture. The file must survive content changes, team reuse, developer inspection, code mapping, and model consumption. - Accept whatever Figma-related input the user supplies. Classify what is knowable, name evidence gaps, and ask only when missing information blocks the requested confidence level. - Preserve the existing `author`, `review`, and `repair` surfaces. App/source fidelity audits live inside `review`; do not create a new runtime mode selector. - Use adaptive reference selection. Load the smallest owned reference set that fits the task, then compose tools and evidence levels instead of following a mandatory workflow. - Keep Figma clean. Long reports, duplicate indexes, source maps, acceptance matrices, and worklogs belong in repo docs or chat, not as canvas text. The only text-heavy native Figma page is `Index`, and it is a map, not a report. - Preserve Figma-native judgment. Do not turn this into a keyword checklist or insist on Auto Layout for illustrations, expressive hero art, FigJam, or other intentionally free-form work. - For tool-mediated Figma work, treat successful MCP/API responses as provisional. Verify actual file state with returned node IDs, structure reads, fill reads, bounds checks, and screenshots of the target artifact. - For audit work, default to read-heavy inspection. Write to Figma only when the user asks for authoring or repair, then verify with readback and visual proof. - Do not treat tool success, `get_metadata`, upload hashes, generated component names, local component existence, screenshot resemblance, or name similarity as proof by themselves. - A source-backed claim must name the source component, token source, asset source, runtime state, screenshot, product decision, or verification anchor that owns the truth. If that evidence is unavailable, use `Evidence only`, `Blocked`, or another bounded verdict rather than inventing a pass. - A pixel-perfect or visual-parity claim requires an explicit source pair, render proof, dimensions, normalization, ignored regions, and blocker disclosure. - Keep generated and imported Figma work clearly separated from canonical library work. A plausible local component is not canonical until it is source-mapped, named, and verified. - Runtime doctrine must stay self-contained in this skill package. Do not route users to planning docs, local source packs, or hidden repo context to understand the guidance. ## First Move 1. Start from the user's actual artifact or complaint. Do not reject partial, vague, mixed, or indirect inputs up front. 2. Classify the job as `author`, `review`, or `repair`. 3. Classify the artifact role before judging it: canonical, evidence, approximate, stale, draft/exploration, research/reference, out of scope, blocked, or not inspected. 4. Load references by need: - Always read `references/figma-file-craft.md` for detailed Figma guidance. - Read `references/figma-mcp-agent-gotchas.md` for MCP/API inspection, writes, uploads, exports, screenshots, or tool-mediated repair. - Read `references/figma-source-backed-parity.md` when the artifact claims production truth from code, tokens, assets, screenshots, or runtime behavior. - Read `references/figma-audit-toolkit.md` for audits, evidence-ranked verdicts, target/app matching, duplicate/stale cleanup, report contracts, or broad file sweeps. - Read `references/figma-visual-fidelity.md` for source-pair manifests, screenshot/reference handling, fast structural scans, exact asset checks, deterministic capture expectations, or visual parity claims. 5. Identify the consumers that matter: designers, developers, Code Connect, Make, Sites, Buzz, Slides, MCP/IDE agents, or non-designer template users. 6. If a real file, node, screenshot, or source path is available, inspect it before prescribing fixes. If no artifact is available, produce a concrete structure, audit plan, or evidence boundary instead of inventing file facts. ## Working Posture For authoring: - Provide Figma-native structure: pages, `Index`, sections, frames, components, variables, modes, component properties, descriptions, Dev Resources, and handoff surfaces. - Keep canvas chrome consistent across the file. Product theme belongs inside mockup frames, not in random page backgrounds or section fills. - Use component descriptions and Dev Resources for compact source truth; use external docs for long proof. For review: - Lead with prioritized findings and evidence. Distinguish file-craft issues from product-design opinions. - Classify artifacts before reuse. Screenshots, generated components, imported boards, and approximate repairs are evidence until source-backed proof promotes them. - Use verdicts that match the evidence: `Pass`, `Partial`, `Fail`, `Evidence only`, `Blocked`, `Not inspected`, or `Out of scope`. - `Partial` is evidence grading, not approval. It must name the missing proof or missing artifact work before the requested confidence can be reached. For readiness questions, treat `Partial` as not ready unless the user asked only for triage. - For fidelity claims, require source-pair identity and rendered or explicitly blocked visual evidence. For repair: - Give the smallest ordered repair path that restores structural honesty without overbuilding. - Remove or relabel duplicate, stale, generated, or approximate artifacts that would pollute component search or Assets surfaces. - Update `Index`, descriptions, Dev Resources, component names, and handoff notes when the repair changes file conventions or source ownership. ## Output Expectations - `author`: a concrete Figma structure, naming scheme, variable/component architecture, or handoff plan with relevant tradeoffs. - `review`: findings first, ordered by downstream impact, with file/source evidence and explicit blockers. - `repair`: an ordered fix plan that names what to convert, rename, tokenize, componentize, annotate, deprecate, delete, or verify. - Audit outputs should live in chat or repo docs. Use checklists and ledgers only when the task needs them: compliance checklist, coverage, app-fidelity match surface, authorship, handoff readiness, style-guide gaps, duplicate/stale artifacts, verification receipts, or repair plan. - Include a short acceptance check that a human or agent can run against the Figma artifact or source evidence. ## Reference Map - `references/figma-file-craft.md` - Figma file-craft doctrine for layout, components, variables, styles, libraries, page organization, `Index`, Dev Mode, Code Connect, AI surfaces, MCP readiness, and anti-patterns. - `references/figma-mcp-agent-gotchas.md` - operational gotchas for Figma MCP/API work, including page context, fonts, component properties, uploads, screenshots, readback, bounds, and source-of-truth checks. - `references/figma-source-backed-parity.md` - source-truth discipline for production-backed Figma components and parity claims, including code, token, asset, runtime, and claim-boundary semantics. - `references/figma-audit-toolkit.md` - audit toolkit for permissive intake, artifact roles, evidence tiers, verdicts, severity, target/app matching, duplicate/stale review, clean reporting, and repair contracts. - `references/figma-visual-fidelity.md` - visual-fidelity method for source pairs, screenshots, fast structural scans, exact asset checks, deterministic captures, normalized comparison, and pixel-parity boundaries.
