What it does

Patentfig is an agent skill from davila7/claude-code-templates. Generate patent-office-compliant figures via the PatentFig AI API — patent line art from text (PNG or SVG), vectorize drawings to SVG/DXF/vector PDF, AI-upscale images, and convert to filing-ready TIFF/PDF/PNG. Use when the user asks for patent drawings, patent figures, invention diagrams, USPTO/EPO-compliant line art, vectorizing a drawing for CAD, or preparing figures for a patent filing. Requires a PATENTFIGAPIKEY environment variable.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/endpoints.md`).

It sits in Legal & Compliance, covering Intellectual property, Diagrams and Secrets management. The repository describes itself as: CLI tool for configuring and monitoring Claude Code. The licence is MIT.

When your agent uses it

  • The user asks for patent drawings
  • Invention diagrams
  • USPTO/EPO-compliant line art
  • Vectorizing a drawing for CAD

Example prompts

  • “/patentfig”

Requirements

  • A credential in PATENTFIG_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 46b4d8b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • patentfig.ai
    • cdn.patentfig.ai

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • PATENTFIG_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Patentfig loads about 1.2k tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 114 tokens; SKILL.md has 444 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~114
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

PatentFig AI API

Generate and convert patent figures through the PatentFig AI REST API.

  • Base URL: https://patentfig.ai/api/v1
  • Auth: Authorization: Bearer $PATENTFIG_API_KEY
  • All endpoints are synchronous and return JSON: { "success": true, "data": {...} } on success, { "success": false, "error": { "code", "message" } } on failure.
  • Generated files are returned as URLs on https://cdn.patentfig.ai — pass them to the user or feed them into follow-up calls.

Setup

The key comes from the PATENTFIG_API_KEY environment variable. Never hardcode it, print it, or write it into files or logs.

If the variable is not set, tell the user to create a key at https://patentfig.ai/settings/api-keys (requires a PatentFig AI account; keys start with pfig_) and export it:

bash
export PATENTFIG_API_KEY="pfig_..."

Verify connectivity and credit balance (free call):

bash
curl -s https://patentfig.ai/api/v1/credits \
  -H "Authorization: Bearer $PATENTFIG_API_KEY"
# → { "success": true, "data": { "balance": 500 } }

Generate a patent figure (10 credits)

POST /figures — the core endpoint. One prompt → one figure. Views, diagram type, and composition are all controlled through the prompt; for a multi-view set (front/side/top), make one call per view.

bash
curl -s -X POST https://patentfig.ai/api/v1/figures \
  -H "Authorization: Bearer $PATENTFIG_API_KEY" \
  -H "Content-Type: application/json" \
  --max-time 300 \
  -d '{
    "prompt": "Exploded view of a wireless earbud charging case showing lid, hinge, charging coil, and battery",
    "output": "svg",
    "labeled": true
  }'
  • output: "png" (raster figure) or "svg" (stroke-based line art, CAD-friendly). Default "png".
  • labeled: true adds patent-style numeric reference callouts (100, 102, …).
  • referenceImageUrls: up to 4 public image URLs (sketch/photo/prior figure) used as the structural baseline.
  • Response data.url is the figure; with output: "svg" the full SVG source is also in data.svg.

Prompting tips: name the parts to draw (names tell the model WHAT to draw, not what to label); for flowcharts/block diagrams, name every node explicitly.

Convert an existing image

All three endpoints accept either JSON with imageUrl (public URL) or multipart/form-data with a file field (PNG/JPEG/WebP/TIFF, ≤10 MB).

Vectorize (20 credits) — raster → SVG / DXF / vector PDF:

bash
curl -s -X POST https://patentfig.ai/api/v1/vectorize \
  -H "Authorization: Bearer $PATENTFIG_API_KEY" \
  -H "Content-Type: application/json" \
  --max-time 300 \
  -d '{ "imageUrl": "https://example.com/drawing.png", "format": "dxf", "engine": "lineart" }'

engine: "lineart" (default) redraws as clean single-stroke patent line art — use for CAD/DXF. engine: "trace" reproduces the input pixels faithfully, preserving fills — use when output must match the original.

Enhance (20 credits) — AI super-resolution: POST /enhance with scale (2 or 4, controls pixels) and dpi (300 or 600, metadata stamp only).

Convert (20 credits) — filing-ready raster: POST /convert with format (png/tiff/pdf) and dpi (300 or 600).

Full parameter tables for every endpoint: see references/endpoints.md. Machine-readable spec: https://patentfig.ai/api/openapi.yaml

Operational rules

  • Set a client timeout of at least 300 seconds — generation and vectorization take from ~20s up to a few minutes.
  • Credits are charged only on success; retrying a failed call never double-bills.
  • Rate limit: 60 requests/minute per key. On 429 back off (start at 5s) and retry.
  • On 402 INSUFFICIENT_CREDITS, stop and tell the user to top up at https://patentfig.ai/pricing.
  • On 500 GENERATION_FAILED, one retry is reasonable; persistent failures usually mean the input doesn't suit the pipeline (e.g., a photo sent for line-art vectorization — suggest POST /figures with the photo as referenceImageUrls instead).
  • Before a batch of billable calls, check GET /credits and confirm the balance covers it.
