patent-check

patent-check is a command for Claude Code from illusionaireal/oh-my-patent. It costs 0 tokens per session (337 once invoked), scanned A, original, MIT.

A readiness check for a patent project, covering the active coding-agent adapter, search services, external tools, runtime, workspace, and saved project states.

In plain words
What is it for?
Use `/patent-check` for the current workspace or another project path to check services such as Google Scholar and patent databases, tools such as Mermaid and Git, Node.js, write access, and existing project state files.
Why use it?
It shows which setup items are missing before research begins without changing configuration or installing anything.

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

patent-check 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 12d 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

/patent-check

Run environment readiness check before starting or resuming a patent project.

Usage

/patent-check [project-path]

If no project path is given, checks the current workspace.

What It Does

  1. Detects which adapter (Claude Code / Codex / OpenCode) is active
  2. Checks all configured MCP servers against required list:
    • google_scholar (required)
    • uspto_patent (recommended)
    • semantic_scholar (optional)
    • cnipa_patent (recommended for CN jurisdiction)
  3. Checks external tools:
    • mmdc (Mermaid CLI) - blocking if missing
    • PlantUML server reachability
    • git
  4. Checks runtime:
    • Node.js version >= 18
    • Workspace directory writable
  5. Scans existing projects in projects/ directory:
    • Validates state.json for each project
    • Reports current stage

Output

The check produces a structured report to the terminal and optionally writes it to references/init-report.md if a project path is provided.

Behavior

  • Does NOT modify any configuration files
  • Does NOT install missing tools or MCP servers
  • Provides setup guidance for missing items
  • Only mmdc and git missing will block the workflow
  • Missing MCP servers produce warnings, not blocks

Integration

  • Runs automatically at INIT stage via the patent-init-sentinel agent
  • Can be run manually anytime via this command
  • Report can be consumed by archimedes to decide whether to proceed to RESEARCH
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.
