This skill assists in planning, running, and evaluating reliability and instruction-drift soak tests for AI agent harnesses and models. It is designed for use with the Soak framework, providing evaluation guidance without installing the runner or exercising a live target.
What this skill does
Define target and budget bounds: Clearly specify the agent harness, model, workload, environment, and pass/fail criteria. Establish duration, request rate, concurrency, and spending limits before engaging any external service.
Design deterministic, sanitized cases: Assign each test case a stable unique ID with explicit and observable assertions. Ensure all inputs and outputs are free from sensitive data.
Verify adapter with a 1-run smoke test: Implement the input/output adapter of the runner and execute a short smoke test against the actual target to validate the setup prior to multiple iterations.
Enforce runtime and spend limits: Execute tests with defined duration, per-call timeouts, intervals, and maximum iteration constraints while retaining records.
Who it is for
This skill is beneficial for developers and teams utilizing AI coding agents like Claude Code, Cursor, and Codex, especially those focused on enhancing the reliability and testing of AI agent components under prolonged usage conditions.
Use cases
Evaluate AI agent steadiness and responsiveness over extended periods in a controlled testing environment.
Assess instruction drift resistance to confirm the consistent performance of AI models and harnesses.
Validate system readiness before deploying AI solutions in live environments or scaling up existing solutions.
Technical details
This skill uses capabilities such as agent-governance, aiapplication, and agent-soak-testing. It operates alongside the Soak framework (accessible on GitHub) but is not responsible for installing or executing the runner itself. Users must prepare their environment and ensure compliance with any necessary terms or conditions related to external services used.
