workflows-development

workflows-development is a skill for Claude Code from CrowdStrike/foundry-skills. It costs 92 tokens per session (5,173 once invoked), scanned A, original, MIT.

A workflow-building skill for Falcon Fusion, CrowdStrike’s system for connecting security tasks into automated sequences. It creates workflow definitions in YAML, a plain-text configuration format.

In plain words
What is it for?
It is for creating and configuring Fusion workflows, including their triggers, actions, step order, error handling, and variable references.
Why use it?
It helps turn repeated security procedures into defined, multi-step automations without having to work out the workflow format from scratch.

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

workflows-development 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 18d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/action_search.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.

Foundry Workflows Development

Write every workflow definition in Fusion YAML, validate step dependencies before running it, and handle failures with conditional routing and action-level flags (Error Handling) — Fusion has no onError blocks and no built-in retry.

Part of a suite. If development-workflow has not already run, and this is a new app or its first capability, load the development-workflow skill first — it owns the CLI prerequisite check, scaffolding order, and manifest coordination.

Falcon Foundry Workflows are YAML-defined automation units executed by the Falcon Fusion engine. They orchestrate multi-step operations across Functions, Collections, CrowdStrike APIs, and RTR sessions with parallelism and state management.

Prerequisites

  • Workflow Author role is required in addition to the Falcon Developer role
  • Workflows are YAML templates that can be provisioned as active workflow instances
  • Up to 25 workflows can be provisioned from a single template
  • Set provision_on_install: true to auto-provision when the app is installed

CLI Scaffolding

# Write the workflow YAML to /tmp/ first — the CLI copies it into workflows/
foundry workflows create --name "my-workflow" --spec /tmp/workflow.yaml --no-prompt
# After: edit workflows/my-workflow.yml to refine workflow logic

Discover Available Actions and Triggers

foundry workflows actions view --name "send email" --no-prompt              # Look up by name
foundry workflows actions view --name "send email" --no-prompt --output-schema  # Output schema
foundry workflows actions view --name "send email" --no-prompt --mock       # Mock output
foundry workflows triggers view --no-prompt                                 # List triggers

Always use --no-prompt on actions view and triggers view. As of CLI 2.1.1, multiple matches are listed non-interactively. On older CLIs, partial matches trigger an interactive prompt that fails in headless environments (Error: no TTY available). The bundled action_search.py is an alternative that works without a manifest directory — see references/action-discovery.md.

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.

workflows-development is a skill published in the GitHub repository CrowdStrike/foundry-skills (35 stars, last pushed today), licensed MIT. It adds 92 tokens to every session and 5,173 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
