Curated by Skill Harbor — a migration skill for escaping Firebase Extension lock-in: it converts an installed Extension (or its source) into either a local Cloud Functions codebase under functions/src/ for direct app integration, or a publishable npm package exporting V2 functions. It modernizes 1st-gen triggers to 2nd-gen with a destructuring compatibility shim, and enforces native SDK rules — declarative IAM instead of manual gcloud scripts, parameterized config, SDK lifecycle hooks, never calling .value() at module top-level. Distinct from the 7 firebase skills already published (ai-logic-basics, app-hosting-basics, auth-basics, crashlytics, data-connect, firestore, security-rules-auditor) — those are feature basics, this one is a migration workflow. By @firebase, listed here with credit to its creator. Honest caveats: migrations touch live infrastructure — review the generated code and IAM declarations before deploying; it assumes Node >= 22 and firebase-functions >= 6. Skill Harbor never reviews the code, review it yourself before use.

Install
Prerequisites: a Firebase project with an installed Extension to migrate; Node >= 22, firebase-functions >= 6 Install "Extension to Functions Codebase" for me. Convert an installed Firebase Extension into a standalone Cloud Functions codebase or a publishable npm package — V1 to V2 trigger upgrades included Repository: https://github.com/firebase/agent-skills/blob/main/skills/extension-to-functions-codebase/SKILL.md 1. Fetch the SKILL.md file for the firebase-extension-to-functions-codebase skill from the repository into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "firebase-extension-to-functions-codebase". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. any accounts, API keys, or CLI tools mentioned in the prerequisites above). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. Never ask me to paste secrets in chat — credentials go through the secure vault or environment variables. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
