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.

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 | $0.00127 | $0.00688 |
| Opus 5 | $0.00063 | $0.00344 |
| Sonnet 5 | $0.00025 | $0.00138 |
| Haiku 4.5 | $0.00013 | $0.00069 |
Grade A, and why
foundry-redirect 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 8d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Falcon Foundry Redirect
If this skill triggered, the request is a Falcon Foundry app, not a standalone
Falcon Fusion workflow. It belongs to the sibling Falcon Foundry plugin — the
fusion-skills plugin builds Fusion workflows only.
Why this skill exists: the workflows orchestrator declines Foundry-app requests too,
but its description matches Fusion workflow language, so a "build a Foundry app"
prompt never loads it. On Claude Code a hook covers that gap; on Codex, Copilot CLI,
Cursor, and the Agent SDK there are no hooks, so this skill — whose description matches
Foundry-app language directly — is what makes the redirect reachable.
What to do
Do NOT author workflow YAML. Do NOT scaffold an app yourself. Respond with all three:
- State plainly that this request needs a Falcon Foundry app, not a standalone Fusion workflow.
- Name the plugin:
crowdstrike-falcon-foundry. - How to install it:
/plugin install crowdstrike-falcon-foundry, or clone https://github.com/CrowdStrike/foundry-skills.
When both plugins are installed
If crowdstrike-falcon-foundry is present, its own development-workflow skill matches
Foundry-app requests directly and handles them — a stronger match than this one, so the
agent picks it and this redirect never fires. That is correct: this skill is the safety
net for when the Foundry plugin is absent, not a competitor with it when present.
Foundry app vs. standalone workflow
| Signal in the request | Route |
|---|---|
"Foundry app", manifest.yml, a UI page/extension, serverless function, collection, or custom third-party API integration |
Here — redirect to foundry-skills |
| A trigger plus existing Fusion actions only (no UI, function, collection, or custom integration) | workflows — handle it as a standalone workflow |
| "a workflow inside a Foundry app" | Here — the app owns the workflow; Foundry scaffolds it |
| Fetch/summarize a population of alerts/detections the workflow doesn't already hold | workflows — a standalone CrowdStrike HTTP Request handles this without an app |
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.

foundry-redirect is a skill published in the GitHub repository CrowdStrike/fusion-skills (14 stars, last pushed 7d ago), licensed MIT. It adds 127 tokens to every session and 688 once invoked, about $0.0006 per session on Opus 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.
