pn-figma

pn-figma is a cursor rule for coding agents from perniemann/pnCore. It costs 230 tokens per session, scanned A, original, MIT.

A set of rules for turning Figma designs into code and keeping the design and implementation aligned. Figma is a collaborative tool for designing user interfaces.

In plain words
What is it for?
Use it when implementing a Figma design, extracting its reusable style values, mapping frames to components, or updating code after design changes.
Why use it?
It prevents mismatched component names, spacing, typography, and colors, while making unclear design choices visible.

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

pn-figma 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 4d 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

Figma rules

  • Extract design tokens (colors, spacing, typography) from Figma before implementing; use tokens in code, not raw values from the design.
  • Map Figma components/frames to React/Astro components with consistent naming; sanitize layer names (PascalCase for components, kebab-case for CSS).
  • Use Figma auto-layout semantics when implementing: flex/grid with gap for spacing; preserve direction and alignment.
  • Document intentional deviations from design; when specs are ambiguous, use design-system conventions and note assumptions.
  • Keep token definitions in sync with Figma styles when design is the source of truth; update tokens before components when designs change.
  • Use Figma MCP when available for direct token extraction and component inspection; fall back to manual export when MCP is unavailable.
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.
