What it does

Patent Drafter is an agent skill from revfactory/harness-100. A full patent specification drafting pipeline. An agent team collaborates to generate prior art search, claims, specification, and drawing descriptions in a single pass. Use this skill for contexts such as 'write a patent specification', 'patent application', 'invention patent', 'draft claims', 'prior art search', 'patent draft', 'patent specification draft', 'convert invention report to patent', 'turn an idea into a patent', and other patent specification drafting tasks. Note: Actual patent office filing, patent…

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Legal & Compliance, covering Intellectual property. The licence is Apache-2.0.

When your agent uses it

Contexts such as write a patent specification
Patent application
Invention patent
Prior art search

Example prompts

“write a patent specification”
“patent application”
“invention patent”
“/patent-drafter”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Preparation (Performed Directly by Orchestrator)
Team Assembly and Execution
Integration and Final Deliverables

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Patent Drafter loads about 1.8k tokens when it runs. Until then it costs about 175 tokens; SKILL.md has 688 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~175
When it runs · the whole SKILL.md, loaded when a task matches: ~1.8k

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.

Patent Drafter — Patent Specification Drafting Pipeline

Converts an invention's technical idea into a systematic patent specification set.

Execution Mode

Agent Team — 5 agents communicate directly via SendMessage and cross-verify each other's work.

Agent Composition

Agent	File	Role	Type
prior-art-researcher	`.claude/agents/prior-art-researcher.md`	Prior art search, novelty/inventive step analysis	general-purpose
claim-drafter	`.claude/agents/claim-drafter.md`	Independent/dependent claim drafting, claim scope design	general-purpose
specification-writer	`.claude/agents/specification-writer.md`	Detailed description of invention, embodiment writing	general-purpose
drawing-designer	`.claude/agents/drawing-designer.md`	Drawing composition, reference numeral descriptions	general-purpose
patent-reviewer	`.claude/agents/patent-reviewer.md`	Consistency cross-verification, description deficiency check	general-purpose

Workflow

Phase 1: Preparation (Performed Directly by Orchestrator)

Extract from user input:
- Title of Invention: Technical title
- Technical Field: The field to which the invention belongs
- Invention Overview: Core technical concept, components, operating principles
- Problem to be Solved: Problems with existing technology and the problem to be solved
- Existing Materials (optional): Invention report, technical documents, prototype information
Create the _workspace/ directory in the project root
Organize the input and save to _workspace/00_input.md
Determine the execution mode based on the requested scope

Phase 2: Team Assembly and Execution

Order	Task	Owner	Dependencies	Output
1	Prior Art Search	prior-art-researcher	None	`_workspace/01_prior_art_report.md`
2	Claim Drafting	claim-drafter	Task 1	`_workspace/02_claims.md`
3a	Specification Writing	specification-writer	Tasks 1, 2	`_workspace/03_specification.md`
3b	Drawing Design	drawing-designer	Task 2	`_workspace/04_drawings.md`
4	Patent Review	patent-reviewer	Tasks 1, 2, 3a, 3b	`_workspace/05_review_report.md`

Tasks 3a (Specification) and 3b (Drawing) are executed in parallel. Both depend on claims, so they can start simultaneously after Task 2 is complete. However, both sides communicate for reference numeral coordination.

Inter-agent Communication Flow:

prior-art-researcher completes -> Delivers differentiation points and design-around direction to claim-drafter
claim-drafter completes -> Delivers elements and terms to specification-writer, structure to drawing-designer
specification-writer <-> drawing-designer: Mutual coordination of reference numeral system
patent-reviewer cross-verifies all deliverables. If Red must-fix items found, requests revision from relevant agent (up to 2 times)

Phase 3: Integration and Final Deliverables

Review all files in _workspace/
Verify that all Red must-fix items from the review report have been addressed
Report the final summary to the user:
- Prior Art Search Report — 01_prior_art_report.md
- Claim Set — 02_claims.md
- Detailed Description of Invention — 03_specification.md
- Drawing Description — 04_drawings.md
- Review Report — 05_review_report.md

Modes by Request Scope

User Request Pattern	Execution Mode	Agents Deployed
"Write the full patent specification"	Full Pipeline	All 5 agents
"Just search prior art"	Search Mode	prior-art-researcher only
"Just draft claims"	Claims Mode	claim-drafter + reviewer
"Write spec from these claims" (existing claims)	Specification Mode	specification-writer + drawing-designer + reviewer
"Review this specification"	Review Mode	patent-reviewer only

Show full SKILL.md (282 more words)Show less

Data Transfer Protocol

Strategy	Method	Purpose
File-based	`_workspace/` directory	Storing and sharing main deliverables
Message-based	SendMessage	Real-time delivery of key info, numeral coordination, revision requests

File naming convention: {order}_{agent}_{deliverable}.{extension}

Error Handling

Error Type	Strategy
Web search failure	Prior art researcher works based on general knowledge, notes "DB search not performed"
Insufficient invention info	Request additional info from user, draft with minimum information
Agent failure	Retry once -> if failed, proceed without that deliverable, note omission in review report
Red items found in review	Request revision from relevant agent -> rework -> re-verify (up to 2 times)
Reference numeral mismatch	drawing-designer and specification-writer mutually coordinate

Test Scenarios

Normal Flow

Prompt: "Write a patent specification for an IoT-based smart flowerpot automatic watering system. It measures with a soil moisture sensor and AI adjusts the watering amount based on plant type." Expected Results:

Prior Art Search: 5+ prior patents related to IoT watering systems and smart flowerpots
Claims: Apparatus independent claim + method independent claim + 5+ dependent claims
Specification: Complete structure from technical field through embodiments
Drawings: System block diagram + detailed structure diagram + flowchart
Review: All consistency matrix items verified

Partial Flow

Prompt: "Just search prior art for this invention idea" Expected Results:

Switches to search mode (prior-art-researcher only)
Prior art list + in-depth analysis + novelty/inventive step assessment

Error Flow

Prompt: "Write a patent specification, the idea is new battery technology" Expected Results:

Full pipeline execution, additional questions due to insufficient invention details
When drafting with minimum info, many items marked "inventor verification needed"
Review report includes "recommend rewriting after supplementing detailed information"

Agent Extension Skills

Agent	Extension Skill	Purpose
claim-drafter, patent-reviewer	`claim-drafting-patterns`	Claim drafting patterns, claim scope design strategy
prior-art-researcher	`prior-art-search-strategy`	Prior art search strategy, novelty/inventive step analysis framework
