Gplay Vitals Monitoring

What it does

When your agent uses it

• Query crash/ANR rates
• Detect release regressions with anomaly detection
• Filter error issues/reports with AIP-160 expressions
• Break down startup/rendering/battery metrics by dimension

Example prompts

• “/gplay-vitals-monitoring”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

1. 1Watch after every release. Run vitals crashes anomalies scoped to the rollout window first — it surfaces regressions without you setting…
2. 2Confirm the trend. vitals crashes query --type crash and --type anr for the rate; add --dimension versionCode to confirm the new build is…
3. 3Triage. vitals errors issues --filter 'errorIssueType = CRASH' --order-by 'errorReportCount desc' to rank by impact.
4. 4Drill in. Take the issue id and run vitals errors reports --filter 'errorIssueId = ' for stack traces and device breakdown.
5. 5Track ANRs separately — they weigh heavily on Play ranking; always check --type anr distinctly.

What it can do on your machine

Read from SKILL.md and the folder at commit f43f001. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • jq

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gplay Vitals Monitoring loads about 1.8k tokens when it runs. Until then it costs about 110 tokens; SKILL.md has 485 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~110

When it runs · the whole SKILL.md, loaded when a task matches

~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Monitor Android app stability and performance from the Play Developer Reporting API via gplay vitals. Use to query crash/ANR rates, detect release regressions with anomaly detection, filter error issues/reports with AIP-160 expressions, and break down startup/rendering/battery metrics by dimension. Use when asked to check crash rates, ANR rates, error trends, performance data, or to gate a release on stability.
