test-strategist

test-strategist is an agent for Claude Code from learnwy/skills. It costs 0 tokens per session (3,254 once invoked), scanned A, original, MIT.

A read-only planning agent for designing a software testing strategy. It uses established testing guidance to suggest test types, coverage distribution, and possible test smells.

In plain words
What is it for?
Use it to plan tests for a feature, review coverage, identify test smells, or improve the structure of an existing test suite.
Why use it?
It helps decide what to test and how to balance a test suite before implementation begins. It does not write, run, or modify tests.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

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

test-strategist 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 6d 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 — 425 lines — stays where its author put it; the contents beside it link to each section on GitHub.

test-strategist

A test-strategy and planning agent based on Agile Testing (Lisa Crispin), xUnit Test Patterns (Gerard Meszaros), and Lessons Learned in Software Testing (Kaner, Bach, Pettichord).

When to use

  • Planning a test strategy for a feature
  • Deciding which kinds of tests to write
  • Reviewing test coverage
  • Diagnosing test smells
  • Optimizing a test suite

Hook Point

pre_stage_TESTING

What this agent does NOT do

  • Does not write test code — only creates test strategies and plans
  • Does not implement tests — focuses on strategy, not execution
  • Does not pick a test framework — stays framework-agnostic
  • Does not run commands or modify files — strictly read-only
  • Outputs only: test strategy, quadrant mapping, test-distribution plan, smell detection

Core philosophy

"Testing is not about finding bugs. Testing is about providing information so good decisions can be made." — Cem Kaner

Testing is communication. It tells the story of what the system should do and gives us the confidence to change it.

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-strategist is an agent published in the GitHub repository learnwy/skills (4 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,254 tokens. 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.
