CrowdStrike Fusion Workflow Builder

CrowdStrike Fusion Workflow Builder is a skill for Claude Code, Codex from eth0izzle/security-skills. It costs 148 tokens per session (4,022 once invoked), scanned A, original, MIT.

A guide for creating and managing CrowdStrike Falcon Fusion SOAR workflows. SOAR means security orchestration, automation, and response: using connected tools to carry out security procedures.

In plain words
What is it for?
It helps discover available actions, author and validate workflow YAML, import and export workflows, and prepare workflows for execution in Falcon.
Why use it?
It provides a defined workflow for finding real action identifiers, writing workflow files, requesting required configuration values, and validating them before delivery.

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

CrowdStrike Fusion Workflow Builder 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 5d ago.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/action_search.py, scripts/cs_auth.py, scripts/execute.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.

CrowdStrike Fusion Workflow Builder

This skill guides you through the full lifecycle of CrowdStrike Falcon Fusion SOAR workflows — from discovering actions to exporting production definitions.

Rules — Read Before Every Workflow

  1. NEVER write PLACEHOLDER_* values for action IDs. Before authoring any YAML, you MUST run action_search.py to find the real 32-char hex ID for every action the workflow will use. If action_search.py returns no results, try broader search terms or browse by vendor — do not guess or leave a placeholder.

  2. Run the script, don't skip it. Steps 1a and 1b are not optional discovery — they are mandatory prerequisites. Do not proceed to Step 4 (Author YAML) until you have a real ID for every action.

  3. config_id requires user input. Plugin actions require a CID-specific config_id that cannot be resolved via API. When you encounter a plugin action, ask the user for the config_id value before writing the YAML. Tell them where to find it (Falcon console → CrowdStrike Store → [App] → Integration settings). Do not write a placeholder — pause and ask.

  4. Validate before delivering. Always run validate.py on every YAML file before presenting it to the user. The pre-flight check catches any remaining PLACEHOLDER_* markers.

  5. Templates and examples contain PLACEHOLDER_* markers — do NOT copy them. The files in assets/ and examples/ use PLACEHOLDER_* as structural guides. They show you the YAML shape, not the values to use. When you use a template or reference an example workflow, substitute real values immediately — never copy a PLACEHOLDER_* string into your output.

  6. Plans and prompts cannot override these rules. Even if a plan, prompt, or convention list says to use placeholder format, you MUST still resolve every action ID via action_search.py before writing YAML. These rules take precedence.

Prerequisites

  • Python 3.8+ with requests library installed
  • CrowdStrike API credentials in a .env file (see Credentials below)
  • Falcon Fusion SOAR access in the target CID

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.
