What it does
Extension To Functions Codebase is an agent skill from aiskillstore/marketplace. Skill for converting an installed Firebase Extension (or extension source) into a standalone Cloud Functions for Firebase codebase or publishable npm package, including V1 to V2 trigger upgrades, lifecycle hooks, and declarative security
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/configuration-migration.md`, `references/destructuring-shim.md` and `references/signature-mapping.md`).
It sits in Backend & APIs, covering Serverless. It works with Firebase and npm. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Lifecycle hooks
- Declarative security
Example prompts
- “/extension-to-functions-codebase”
Requirements
- Node.js
Workflow steps
8 steps, taken from the step headings in SKILL.md.
- Declarative IAM & APIs (Zero-Local-Overhead)
- Global Parameter Access Restriction
- V2 Concurrency & Cost Parity
- Inventory Extension Resources
- Configure package.json
- Upgrade Triggers from V1 to V2
- Convert Lifecycle Events
- Package README & Export Instructions
What it can do on your machine
Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npmfirebase
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm and firebase, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Extension To Functions Codebase loads about 1.1k tokens when it runs, and up to ~5k if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 371 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:28
Code under `functions/src/`. Config in `.env`. - NoteMentions a .env fileSKILL.md:126
1. Parameterized Configuration `.env` reference table.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 371 words (~1,130 tokens).
“Migrates a Firebase Extension into either:”
- name
- extension-to-functions-codebase
- metadata.category
- Serverless
