Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00050 | $0.00384 |
| Opus 5.5 | $0.00020 | $0.00154 |
| Sonnet 5.5 | $0.00010 | $0.00077 |
| Haiku 4.5 | $0.00005 | $0.00038 |
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 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.
This is a copy
100% identical to firebase-crashlytics — 1 line 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:
- Android: android_setup.md
- iOS: ios_setup.md
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.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

firebase-crashlytics is a skill published in the GitHub repository pleaseai/claude-code-plugins (16 stars, last pushed 5d ago), licensed MIT. It adds 50 tokens to every session and 384 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to firebase-crashlytics, differing in 1 line, and is treated as a copy.
