Design know-how for ADR-0077 chaos-TDD — deterministic fault injection at existing seams (LLMBackend Protocol / requests HTTP layer) where the fault-injection test states the desired guarded behavior FIRST and the minimal guard lands in the same PR. Use when hardening a pipeline against LLM/external-I/O fault families (truncation, timeouts, 429s, wrong-shaped-but-parseable JSON, flapping backends), when building a fault catalog from operational bug history, when adding hypothesis-based fuzz over LLM output shapes, or when reviewing whether a new pipeline's failure paths abstain with reason codes. NOT for per-event audit log schema design (that is replayable-audit-logs / ADR-0075), NOT for read-only aggregate readings (read-only-instruments / ADR-0071), NOT for single-bug regression pinning after the fact (that is ai-regression-testing — this skill is its front-loaded, catalog-driven counterpart), and NOT for infra-level chaos (chaostoolkit/toxiproxy are the wrong altitude for a single local process).

Quick start
Copy the install prompt. Use the green button above this README.
Send it to your agent. Paste it into your coding agent’s chat and send.
Review the setup. Your agent checks the skill’s instructions, requirements, and installation scope.
