What is figma-context-reader?

A read-only tool for turning Figma designs into structured notes about screens, components, layout, styles, and assets. Figma is a collaborative design application used to plan interfaces before they are coded.

Preparing implementation briefs, checking design-system tokens, reviewing component variants, collecting UX-audit input, and handing design context to developers.

It gives developers evidence-based design details without manually inspecting every part of a Figma file. It also separates information read directly from Figma from visual guesses.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00087	$0.00597
Opus 5	$0.00044	$0.00298
Sonnet 5	$0.00017	$0.00119
Haiku 4.5	$0.00009	$0.00060

Security

Grade A, and why

figma-context-reader 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 10d 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.

Figma Context Reader

Use this skill to turn Figma context into an evidence-backed design brief. This is a read-only skill; route mutations to figma-canvas-editor or figma-design-system-sync.

Modes

frame-brief: summarize a selected frame or page.
component-brief: summarize components, variants, props, and constraints.
token-brief: summarize variables, styles, color roles, spacing, radius, typography, and effects.
audit-input: collect enough Figma evidence for ux-audit-skill or design-critic-skill.
handoff: prepare context for implementation specialists.

Workflow

Confirm the input type: Figma URL, selected node, file key, screenshot/export, or connected MCP selection.
Apply ../../shared/privacy-policy.md.
If a use_figma call is needed, first invoke the installed figma:figma-use skill.
Read only the needed nodes, variables, components, styles, and assets. Avoid broad file scans unless the user asks for library/system work.
Produce a structured context brief with evidence labels. Distinguish direct Figma metadata from visual inference.
If MCP access is unavailable, ask for an export, screenshot, node metadata, or manual Figma details as fallback.

Output Shape

Use assets/context-brief-template.md.

Evidence Rules

Figma metadata: node names, type, layout fields, variables, styles, component names, asset references.
Visual inference: hierarchy, attention, density, likely intent, visual polish.
Missing: anything not available from the current Figma context.

Do not claim DOM, runtime behavior, accessibility scan, or implementation evidence from Figma context alone.

Validation And Eval

Check that the final brief names the evidence source and privacy mode.
Check that every implementation claim is traceable to Figma metadata, visual inference, or an explicit missing-context note.
Use evals/evals.json for forward tests that distinguish connected Figma context from screenshot-only input.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
