Create one verified Linear issue from a Codex Agent Task v1 contract and optionally dispatch it under separate explicit authority. Use when a user asks Codex to create a Linear implementation issue for a repository handled by a mapped Symphony workflow.
Use when designing agent tool schemas, action spaces, or observation formatting, or when diagnosing looping and low completion rates in an agent harness.
Use when an agent is looping, retrying without progress, drifting from its goal, or failing repeatedly — structured capture, diagnosis, contained recovery, and introspection reports.
Use when orchestrating agent workflows — eval-first execution, task decomposition, and cost-aware model routing decisions.
Eval-first AI/ML engineering — RAG decisions, finetune-vs-RAG-vs-prompt framework, prompt-injection defense, structured output, model routing/cost, production drift. Use when working on evals, prompts, RAG, or model optimization.
Use when designing or reviewing an HTTP/RPC API surface — resource modeling, pagination, error envelopes, versioning, idempotency. Falsifiable contracts, not style preferences.
Use when building on the Anthropic Claude API or SDKs — model choice, the tool-use loop, token and context budgeting, prompt caching, batches. Falsifiable patterns for production agents, not SDK hello-worlds.
Use when deciding whether/when to compact the session, or when auditing what is consuming the context window (agents, skills, MCP servers, rules). Compaction timing + token-budget audit in one place.
