Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is tutur3u/platform's own configuration. It tells Claude Code and Codex how to work on platform itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything platform configures →

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-crashlytics 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 today.

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.

Origin

This is a copy

95% identical to firebase-crashlytics — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Crashlytics

This skill provides a complete guide for getting started with Crashlytics on Android or iOS. Crash data collected from client applications can be read using the MCP server in the Firebase CLI.

Prerequisites

Provisioning Crashlytics requires both a Firebase project and a Firebase app, either Android or iOS. To read the data collected by Crashlytics, install the MCP server in the Firebase CLI. See the firebase-basics skill for references.

SDK Setup

To learn how to setup Crashlytics in your application code, choose your platform:

SDK Usage

The SDK provides a number of features to make crash reports more actionable.

  • Add custom keys
  • Add custom logs
  • Set user identifiers
  • Report non-fatal exceptions

To learn how to customize crash reports and add additional debugging data, consult the documentation for your platform.

Changes

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.
