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 | $0.00230 | $0.05805 |
| Opus 5 | $0.00115 | $0.02903 |
| Sonnet 5 | $0.00046 | $0.01161 |
| Haiku 4.5 | $0.00023 | $0.00581 |
Grade A, and why
test-suite-curation 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 10d 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 — 269 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Quick Route
| You want to... | Go to |
|---|---|
| Find which lines/branches each test uniquely covers | Coverage Fingerprinting |
| Decide if "same coverage" means "delete one" | The Coverage-Equality Trap |
| Surface copy-pasted near-duplicate tests | Near-Duplicate Clustering |
| Find never-failing and always-flaky tests | Mining CI History |
| Decide redundant vs obsolete vs low-value vs keep | Prune Decision Rules |
| Split a flat suite into smoke/core/extended | Tiering |
| Safely delete the tests you flagged | Destructive Safety |
| Produce the "what we deleted and why" record | The Audit Record |
Discovery Questions
First, check .agents/qa-project-context.md in the project root and skip anything it already answers. Then clarify:
- Which language/runner? pytest+coverage.py, Jest/Vitest+Istanbul, Go, JUnit — the per-test context mechanism differs per stack (and so does the mutation tool).
- Is there CI test-result history, and how far back? No JUnit/Datadog/Trunk history means you cannot mine never-failing or flaky signals — you only have coverage and clustering.
- What is the suite size and current wall-clock time? This sizes the tiering target (e.g. smoke under 5 min) and whether per-test coverage is feasible in one run or must be sharded.
- What is the business risk map / critical paths? Tiering and the "keep" disposition both depend on it. If absent, run
risk-based-testingfirst. - Who signs off on deletions, and is there a CODEOWNERS file? Deletion is destructive; you need a named approver before this skill removes anything.
- What is the acceptable observation window? How long the team will run quarantined tests as skipped before permanent removal (default: 2 sprints / 2 releases).
What ships with it
7 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.

test-suite-curation is a skill published in the GitHub repository petrkindlmann/qa-skills (117 stars, last pushed 3mo ago), licensed MIT. It adds 230 tokens to every session and 5,805 once invoked, about $0.0011 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.
