Token cost

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.

Security

Grade A, and why

firebase-basics 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 1mo 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 — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Prerequisites

Complete these setup steps before proceeding:

  1. Local Environment Setup: Verify the environment is properly set up so we can use Firebase tools:

  2. Authentication: Ensure you are logged in to Firebase so that commands have the correct permissions. Run npx -y firebase-tools@latest login. For environments without a browser (e.g., remote shells), use npx -y firebase-tools@latest login --no-localhost.

    • The command should output the current user.
    • If you are not logged in, follow the interactive instructions from this command to authenticate.

  3. Active Project: Most Firebase tasks require an active project context.

    [!IMPORTANT] For Agents: Before proceeding with project configuration, you MUST pause and ask the developer if they prefer to:

    1. Provide an existing Firebase Project ID, or
    2. Create a new Firebase project.

    • If using an existing Project ID:

      1. Check the current project by running npx -y firebase-tools@latest use.

      2. If the command outputs Active Project: <project-id>, confirm with the user if this is the intended project.

      3. If not, or if no project is active, set the project provided by the user:

        npx -y firebase-tools@latest use <PROJECT_ID>

    • If creating a new project: Run the following command to create it:

      npx -y firebase-tools@latest projects:create <project-id> --display-name "<display-name>"

      Note: The <project-id> must be 6-30 characters, lowercase, and can contain digits and hyphens. It must be globally unique.

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.
