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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00092 | $0.01856 |
| Opus 5 | $0.00046 | $0.00928 |
| Sonnet 5 | $0.00018 | $0.00371 |
| Haiku 4.5 | $0.00009 | $0.00186 |
Grade A, and why
gplay-vitals-monitoring 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 12d 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.
App Vitals Monitoring
gplay vitals hits the Play Developer Reporting API (separate from the Android Publisher API used by most other commands). Every subcommand outputs JSON by default; add --output table|markdown for humans or --pretty to indent JSON. Dates are ISO 8601 (YYYY-MM-DD).
Preconditions
- Credentials set (
gplay auth loginorGPLAY_SERVICE_ACCOUNT). - Service account needs "View app information and download bulk reports" permission.
- The app must have enough installs to generate vitals data (small apps return empty sets).
The real surface
There are exactly three groups. There is no crashes list/get, no errors list/get, no performance overview/permissions, no --cluster-id, --version-code, --start-time/--end-time, --severity, or --error-id.
| Command | Purpose |
|---|---|
vitals crashes query |
Crash / ANR rate metrics over a date range |
vitals crashes anomalies |
Auto-detected regressions — the release gate |
vitals performance startup|rendering|battery |
Performance metric breakdowns |
vitals errors issues |
Grouped error issues (AIP-160 filterable) |
vitals errors reports |
Individual error reports with stack traces |
Crash & ANR rate metrics
gplay vitals crashes query returns rate metrics, not a cluster list. Switch metric with --type crash|anr; group with --dimension.
# Crash rate for a window
gplay vitals crashes query --package com.example.app --from 2026-06-01 --to 2026-06-30 --output table
# ANR rate
gplay vitals crashes query --package com.example.app --type anr --output table
# Break down by version to spot a bad build
gplay vitals crashes query --package com.example.app --dimension versionCode --output table
# By device model
gplay vitals crashes query --package com.example.app --dimension deviceModel --paginate
Other valid dimensions include deviceModel, deviceBrand, apiLevel, countryCode. Use --paginate to pull every page.
What ships with it
1 file 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.

gplay-vitals-monitoring is a skill published in the GitHub repository hanamizuki/solopreneur (149 stars, last pushed 27d ago), licensed MIT. It adds 92 tokens to every session and 1,856 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
