analyzing-quality-metrics

analyzing-quality-metrics is a skill for Claude Code from jaktestowac/awesome-copilot-for-testers. It costs 80 tokens per session (1,908 once invoked), scanned A, original, MIT.

A system for defining, calculating, and interpreting software quality numbers such as test pass rate, flaky-test rate, test duration, escaped defects, detection time, and code coverage.

In plain words
What is it for?
Use it to build QA dashboards, report testing health, compare releases, investigate flaky tests or growing runtimes, and assess how coverage or bug counts should be used.
Why use it?
It helps teams avoid misleading numbers by explaining what each measure means, what it leaves out, and which decision it supports.

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

analyzing-quality-metrics 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 11d 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.

Analyzing Quality Metrics

Use this skill when someone needs numbers about testing and quality, and the numbers need to survive being acted on.

Every quality metric is a proxy. Coverage proxies for thoroughness, bug count proxies for code health, pass rate proxies for confidence. Proxies are useful until they become targets, at which point they get optimized directly and stop measuring anything. The job here is to pick proxies that resist that, define them precisely enough to be computed the same way twice, and always report the decision the number is meant to inform.

When to Use

  • a stakeholder asks for a QA dashboard or a testing status report
  • a coverage percentage is being used as a quality gate
  • flakiness is being discussed with no measurement behind it
  • suite runtime is growing and nobody can say by how much
  • release quality needs comparing across releases
  • a metric has become a target and the behaviour around it has gone strange

Operating Principles

  • Every metric names the decision it supports. A number nobody acts on is a number nobody should collect.
  • Define before you measure. "Flaky test" and "escaped defect" mean different things to different people; a metric computed two ways is two metrics.
  • Trend over snapshot. A single value is noise. Direction over several releases is signal.
  • Pair every metric with its counterweight. Speed with escape rate, coverage with mutation survival, pass rate with flake rate. A metric reported alone gets gamed alone.
  • Rates, not counts. Ten defects means nothing without the denominator: per release, per thousand changed lines, per user.
  • State the caveat with the number. Coverage without "this measures execution, not assertion" is a misleading number, even when it is correct.
  • Never measure individuals. Bugs found per tester and defects introduced per developer both produce worse work and worse data.

Workflow

Phase 0: Find the decision

Before selecting anything, ask what will be decided differently depending on the answer:
