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 | $0.00038 | $0.00596 |
| Opus 5.5 | $0.00015 | $0.00238 |
| Sonnet 5.5 | $0.00008 | $0.00119 |
| Haiku 4.5 | $0.00004 | $0.00060 |
Grade A, and why
firebase-crashlytics-analytics 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Observe Android app quality and behavior without collecting unnecessary sensitive data.
When to use
- Adding Crashlytics or Analytics.
- Defining event taxonomy.
- Logging non-fatal errors.
- Adding privacy-aware user properties.
- Connecting Remote Config context to diagnostics.
Inputs to inspect
- Events and funnels desired.
- Sensitive data classes.
- Build types and release behavior.
- Privacy policy requirements.
Required workflow
- Define minimal useful events and non-fatal signals.
- Add wrappers if the project already uses abstraction.
- Remove PII from logs/events.
- Differentiate debug and release.
- Validate dashboards or test logs manually.
Rules
- Never log tokens, emails, medical/financial data or secrets.
- Use stable event names.
- Do not use Analytics as authorization.
- Respect consent/opt-out requirements.
- Keep breadcrumbs useful and minimal.

Common mistakes to avoid
- Logging raw exception context with PII.
- Too many noisy events.
- Debug-only verification for release behavior.
- User properties containing sensitive values.
Checklist
- No PII.
- Events documented.
- Non-fatals actionable.
- Build type behavior clear.
- Privacy policy impact mentioned.
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-analytics is a skill published in the GitHub repository GDvega/super-android-kotlin-firebase-skill (2 stars, last pushed 4mo ago), licensed MIT. It adds 38 tokens to every session and 596 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
