Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00092 | $0.05173 |
| Opus 5.5 | $0.00037 | $0.02069 |
| Sonnet 5.5 | $0.00018 | $0.01035 |
| Haiku 4.5 | $0.00009 | $0.00517 |
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.
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.
How it starts
The opening of the file, as written. The whole thing — 389 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
onErrorblocks and no built-in retry.
Part of a suite. If
development-workflowhas not already run, and this is a new app or its first capability, load thedevelopment-workflowskill 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: trueto 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-promptonactions viewandtriggers 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 bundledaction_search.pyis an alternative that works without a manifest directory — see references/action-discovery.md.
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
