dynamo-analyzer

dynamo-analyzer is a skill for Claude Code, Codex from sonomirco/agents-and-commands. It costs 34 tokens per session (906 once invoked), scanned A, original, Apache-2.0.

An analyzer for Dynamo graph files, which describe visual workflows commonly used with Autodesk Revit for building-information modeling. It explains the workflow, extracts embedded Python and DesignScript code, and identifies Revit API usage for C# developers.

In plain words
What is it for?
Use it to document .dyn files, inspect workflow paths and branches, extract code blocks, find Revit API and transaction patterns, or prepare Dynamo automation for porting to C#.
Why use it?
Dynamo graphs can be difficult to understand or convert because their logic is spread across connected visual nodes. This turns the graph into a written report without requiring the Dynamo or Revit program to run.

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

dynamo-analyzer 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 9d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (dynamo_flow_diagram_generator.py, dynamo_script_extractor.py, dynamo_utils.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Dynamo Unified Analyzer

Automatically analyze Dynamo graph definitions (.dyn) to understand workflow structure, extract custom Python and DesignScript code, identify Revit API patterns, and generate comprehensive documentation suitable for porting to C#.

When to use this skill

Use this skill when the user:

  • Asks to analyze a Dynamo file or graph
  • Wants to understand the structure of a .dyn workflow
  • Needs to extract Python scripts or DesignScript code blocks from Dynamo
  • Requests documentation for a BIM automation workflow
  • Mentions converting or porting Dynamo logic to C#
  • Needs algorithmic breakdown of a Revit automation script
  • Wants to understand Revit API usage patterns in a Dynamo graph

What this skill does

  1. Parses Dynamo JSON (.dyn format) without requiring Dynamo/Revit runtime
  2. Builds workflow graph from Nodes and Connectors
  3. Identifies topology: start/end nodes, branching points, merge points, primary workflow paths
  4. Extracts custom code: Python scripts (with engine and I/O) and DesignScript code blocks
  5. Catalogs DSFunctions: ZeroTouch function signatures and Revit API references
  6. Detects patterns: Revit API usage, transactions, FilteredElementCollector patterns
  7. Identifies dependencies: Packages and external library references
  8. Generates comprehensive report with:
    • Executive Summary (purpose, Revit interaction, scope)
    • Workflow Summary (topology and primary flow)
    • Libraries & Dependencies
    • Custom Script Analysis (full Python/DesignScript code with I/O)
    • Algorithmic Analysis (A-E format for C# developers)
    • Definition Summary (node counts, statistics)

How to use

Execute the unified analyzer script:

python ~/.claude/skills/dynamo-analyzer/dynamo-analyzer.py "path/to/file.dyn"

Arguments:

  • Path to .dyn file (Dynamo 2.x JSON format)

Example:

python ~/.claude/skills/dynamo-analyzer/dynamo-analyzer.py ~/Desktop/revit-automation.dyn

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.
