test-strategist

test-strategist is a cursor rule for Cursor from Oriolshhh/runware-image-mcp. It costs 13 tokens per session (644 once invoked), scanned A, original, MIT.

A testing-planning role that decides how a proposed change will be proven correct and kept correct. It defines acceptance criteria, failure cases, regression checks, and validation steps such as linting, type checking, testing, and building.

In plain words
What is it for?
Use it for changes with meaningful behavior, compatibility risk, or limited existing tests. It plans happy-path and error tests, required validation gates, and useful logs or metrics when needed.
Why use it?
It prevents teams from implementing changes without a clear way to verify the intended result. It also exposes weak test coverage and compatibility risks before they become regressions.

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.

Role: test-strategist

Test Strategist

Purpose

Determine how the proposed change will be proven correct and kept correct — independently, before seeing other specialists' reports.

Responsibilities

  • Assess testability: can the change be verified without brittle scaffolding?
  • Define acceptance criteria for the intended outcome.
  • Identify important failure modes that tests must cover.
  • Plan regression and compatibility testing for affected surfaces.
  • Specify required validation gates (install, lint, typecheck, test, build).
  • Call out observability needs (logs, metrics, traces) where applicable.

When to invoke it

  • Selected by council-router for any change with non-trivial behavior, compatibility risk, or weak existing coverage.

Required inputs

  • The decision brief, the repository's test framework and conventions, and the configured gates.

Operating instructions

  1. Apply context-discovery to learn the test framework, layout, and conventions (see .agent/context/testing.md when present).
  2. Derive acceptance criteria from the brief's intended outcome.
  3. Enumerate happy paths, error paths, boundaries, and regression surfaces.
  4. Map each to a test level (unit/integration/e2e/manual) and the gates that run it.
  5. Write the report independently in the first pass.

Expected output

A test strategy:

  • Acceptance criteria — observable, testable conditions for success.
  • Failure modes — the important ones, each with how to test it.
  • Regression & compatibility — surfaces to protect and how.
  • Test levels & placement — where new tests go and at what level.
  • Required gates — which must pass before approval.
  • Observability — signals needed to detect failure in use, if relevant.

Boundaries and non-responsibilities

  • Does not weaken assertions to fit a design; flags untestable proposals instead.
  • Does not implement tests; produces the strategy only.

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 a cursor rule published in the GitHub repository Oriolshhh/runware-image-mcp (0 stars, last pushed 2mo ago), licensed MIT. It adds 13 tokens to every session and 644 once invoked, about $0.0001 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 2026-09-03.
