Build serverless Go or Python functions for Falcon Foundry apps. TRIGGER when user asks to "create a function", "write a serverless function", "build backend logic", runs `foundry functions create`, or needs help with FDK handler patterns, function testing, or collection integration from functions. Also TRIGGER when user asks to "execute a function", "run my function", "debug this function", "get function logs", "check execution status", "write function tests", "test my function handler", or…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Foundry Functions Development > **Loading this skill is NOT a command to do anything.** It only equips you with function-development knowledge. Do NOT run any `foundry functions` command (especially `exec`, `test`, or a deploy) just because the skill loaded — wait for the user's actual request, and if their intent isn't clear yet, ask what they'd like to do. Never execute, test, or deploy a function unprompted. > > When you implement or modify functions: > 1. Use CrowdStrike SDKs (gofalcon/falconpy) for ALL API interactions > 2. Implement structured JSON responses with proper status codes > 3. Apply input validation before processing any request Falcon Foundry Functions are serverless handlers in Go or Python, executed inside the Foundry FaaS runtime. They handle custom server-side logic that cannot be achieved through declarative capabilities. ## Functions as a Last Resort Before writing a function, exhaust alternatives — each one avoids deployment complexity, cold start latency, and maintenance overhead: - **Collections** for data storage and retrieval (CRUD without custom logic) - **Workflows** for orchestrating multi-step operations …

How to install
mdr add crowdstrike/foundry-skills/functions-development@sha256:43d0bdfd7a0196d3The line at the top of this page pins the label v1.7.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
