What it does

Development Assistant is an agent skill from RobThePCGuy/Claude-Patent-Creator. Guides through adding new features, MCP tools, analyzers, and extending the patent creator system.

Its SKILL.md is about 1.3k 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 Agent Workflows, covering Intellectual property and MCP servers. It works with Model Context Protocol, Google BigQuery and Pydantic. The repository describes itself as: USPTO patent creation system with MCP server + Claude Code plugin. Hybrid RAG search over MPEP/USC/CFR, BigQuery access to 76M+ patents, automated 35 USC 112 compliance checks… The licence is MIT.

Requirements

Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Define inputs, outputs, dependencies
Create Pydantic model in mcp_server/validation.py
Add tool function in mcp_server/server.py with decorators
Create test script in scripts/
Update CLAUDE.md

What it can do on your machine

Read from SKILL.md and the folder at commit a089731. 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 (its code samples are python and markdown).
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

Development Assistant loads about 1.3k tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 239 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~30
When it runs · the whole SKILL.md, loaded when a task matches: ~1.3k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NoteMentions a .env fileSKILL.md:173

| Add config | `mcp_server/config.py` | `.env`, `CLAUDE.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.

Development Assistant Skill

Expert system for developing and extending the Claude Patent Creator. Guides through adding new MCP tools, analyzers, configuration options, and features while following best practices and existing patterns.

When to Use This Skill

Activate when adding MCP tools, analyzers, configuration options, BigQuery queries, slash commands, or implementing performance optimizations.

Development Workflow

Feature Request -> Planning -> Implementation (Code + Validation + Monitoring + Tests) -> Testing -> Documentation -> Integration

Adding New MCP Tools

Quick Start:

Define inputs, outputs, dependencies
Create Pydantic model in mcp_server/validation.py
Add tool function in mcp_server/server.py with decorators
Create test script in scripts/
Update CLAUDE.md

Key Decorators:

python

@mcp.tool()                    # Register as MCP tool
@validate_input(YourInput)     # Pydantic validation
@track_performance             # Performance monitoring

Template:

python

def your_tool(param: str, optional: int = 10) -> dict:
    """Comprehensive docstring (Claude sees this).

    Args:
        param: Description
        optional: Description with default

    Returns:
        Dictionary containing: key1, key2, key3
    """
    # Implementation
    return {"result": "data"}

Adding New Analyzers

Overview: Analyzers inherit from BaseAnalyzer and check USPTO compliance.

Minimal Example:

python

from mcp_server.analyzer_base import BaseAnalyzer

class YourAnalyzer(BaseAnalyzer):
    def __init__(self):
        super().__init__()
        self.mpep_sections = ["608", "2173"]

    def analyze(self, content: str) -> dict:
        issues = []
        if violation:
            issues.append({
                "type": "violation_name",
                "severity": "critical",
                "mpep_citation": "MPEP 608",
                "recommendation": "Fix description"
            })
        return {"compliant": len(issues) == 0, "issues": issues}

Adding Configuration Options

Use Pydantic settings in mcp_server/config.py:

python

# In config.py
class AppSettings(BaseSettings):
    enable_feature_x: bool = Field(default=False, description="Enable X")

# In your code
from mcp_server.config import get_settings
if get_settings().enable_feature_x:
    # Feature enabled

Adding Performance Monitoring

python

@track_performance
def your_function(data):
    with OperationTimer("step1"):
        result1 = step1(data)
    with OperationTimer("step2"):
        result2 = step2(result1)
    return result2

Modifying RAG Search Pipeline

Pipeline: Query -> HyDE -> Vector+BM25 -> RRF -> Reranking -> Results

Customization Points: Query expansion, custom scoring, filtering, reranking strategies

Adding New Slash Commands

Create .claude/commands/your-command.md
Add frontmatter: description, model
Write workflow instructions
Restart Claude Code

Template:

markdown

Development Best Practices

Follow existing patterns
Use type hints
Write docstrings (Google style)
Handle errors gracefully
Validate inputs (Pydantic)
Log operations
Monitor performance

Common Development Tasks

Add BigQuery Query: Add method in mcp_server/bigquery_search.py

Add Validation Rule:

python

class YourInput(BaseModel):
    field: str

    @field_validator("field")
    @classmethod
    def validate_field(cls, v):
        if not meets_requirement(v):
            raise ValueError("Error message")
        return v

Add Logging:

python

from mcp_server.logging_config import get_logger
logger = get_logger()
logger.info("event_name", extra={"context": "data"})

Key Patterns

MCP Tool Pattern:

python

@mcp.tool()
@validate_input(InputModel)
@track_performance
def tool_name(param: type) -> dict:
    """Docstring visible to Claude."""
    from module import Component
    if invalid:
        return {"error": "message"}
    result = process(param)
    return {"key": "value"}

Analyzer Pattern:

python

class YourAnalyzer(BaseAnalyzer):
    def analyze(self, content: str) -> dict:
        issues = []
        issues.extend(self._check_x(content))
        return {
            "compliant": len(issues) == 0,
            "issues": issues,
            "recommendations": self._generate_recommendations(issues)
        }
