- Output Build WorkflowGrowthX AI, IncImplement an Output SDK workflow from a plan document. Use when the user asks to build, implement, or code a workflow from an existing plan, or after output-plan-workflow has produced a plan and the user is ready to build.
- Output Credentials EditGrowthX AI, IncView, edit, and set encrypted credentials in an Output.ai project. Use when adding secrets, updating API keys, verifying credential values, or retrieving a specific credential.
- Output Credentials Env VarsGrowthX AI, IncWire encrypted credentials to environment variables using the credential: convention. Use when setting up LLM provider keys (ANTHROPIC_API_KEY, OPENAI_API_KEY) or any env var that should come from encrypted credentials.
- Output Credentials InitGrowthX AI, IncInitialize encrypted credentials for an Output.ai project. Use when setting up credentials for the first time, adding environment-specific credentials, or adding per-workflow credentials.
- Output Debug WorkflowGrowthX AI, IncDebug Output SDK workflow issues. Use when user reports a workflow failing, erroring, hanging, producing wrong results, or asks to debug, troubleshoot, or investigate a workflow execution.
- Output Dev Agent ClassGrowthX AI, IncUse the Agent class for multi-step tool loops, conversation history, streaming progress, and reusable LLM agents. Use when building agents with skills, structured output, stateful conversations, or streaming callbacks.
- Output Dev Code StyleGrowthX AI, IncCode style conventions for Output SDK workflow projects. Use when writing or reviewing any TypeScript/JavaScript code. Discovers the project's own linting rules first; falls back to Output SDK conventions when no linter is configured.
- Output Dev Cost HooksGrowthX AI, IncSubscribe to cost events (cost:http:request, llm:generation:metering) to forward LLM and API spend to your own observability system. Use when adding cost/spend logging, building a cost observability integration, or forwarding per-request cost data to an external system.
- Output Dev Create SkeletonGrowthX AI, IncGenerate workflow skeleton files using the Output SDK CLI. Use when starting a new workflow, scaffolding project structure, or understanding the generated file layout.
- Output Dev CredentialsGrowthX AI, IncStore and reference encrypted secrets in Output SDK workflows using @outputai/core/credentials. Use when integrating API keys, database passwords, or third-party tokens.
- Output Dev Eval TestingGrowthX AI, IncCreate offline evaluation tests for Output SDK workflows using @outputai/evals. Use when implementing test evaluators with verify(), creating dataset YAML files, building eval workflows, or running workflow tests via CLI.

- Output Dev Model SelectionGrowthX AI, IncPick the right LLM model for an Output SDK prompt file. Use when writing a new .prompt file, reviewing a model choice, or upgrading a stale model. Walks through priority (reasoning/balance/speed/cost), provider selection, and a live lookup against the Vercel AI Gateway model index.
- Output Dev Prompt FileGrowthX AI, IncCreate .prompt files for LLM operations in Output SDK workflows. Use when designing prompts, configuring LLM providers, or using Liquid.js templating.
- Output Dev Scenario FileGrowthX AI, IncCreate test scenario JSON files for Output SDK workflows. Use when creating test inputs, documenting expected behaviors, or setting up workflow testing.
- Output Dev Skill FileGrowthX AI, IncCreate .md skill files for Output framework's lazy-loaded instruction system. Use when adding skills to prompts, configuring skill loading, or debugging skill resolution.
- Output Dev Step FunctionGrowthX AI, IncCreate step functions in steps.ts for Output SDK workflows. Use when implementing I/O operations, error handling, HTTP requests, or LLM calls.
- Output Dev Types FileGrowthX AI, IncCreate types.ts files with Zod schemas for Output SDK workflows. Use when defining input/output schemas, creating type definitions, or fixing schema-related errors.
- Output Dev Upgrade Prompt ModelsGrowthX AI, IncBulk-upgrade the model field across .prompt files to the latest version of each prompt's existing family. Use when prompt models have drifted (eg sonnet-4 → sonnet-4-6), after a long pause between framework updates, or as part of a periodic model-freshness pass. Within-family only — never changes provider or tier.
- Output Dev Workflow CostGrowthX AI, IncCalculate and display the cost of an Output SDK workflow execution run. Use when checking LLM token costs, API service costs, or total spend for a specific workflow run.
- Output Dev Workflow FunctionGrowthX AI, IncCreate workflow.ts files for Output SDK workflows. Use when defining workflow functions, orchestrating steps, or fixing workflow structure issues.
- Output Error Direct IoGrowthX AI, IncFix direct I/O in Output SDK workflow functions. Use when workflow hangs, returns undefined, shows "workflow must be deterministic" errors, or when HTTP/API calls are made directly in workflow code.
- Output Error Http ClientGrowthX AI, IncFix HTTP client misuse in Output SDK steps. Use when seeing untraced requests, missing error details, axios-related errors, HTTP calls aren't being properly logged and retried, or paid API costs are missing from cost reports.
- Output Error Missing SchemasGrowthX AI, IncFix missing schema definitions in Output SDK steps. Use when seeing type errors, undefined properties at step boundaries, validation failures, or when step inputs/outputs aren't being properly typed.
- Output Error NondeterminismGrowthX AI, IncFix non-determinism errors in Output SDK workflows. Use when seeing replay failures, inconsistent results between runs, "non-deterministic" error messages, or workflows behaving differently on retry.
- Output Error Try CatchGrowthX AI, IncHandle errors caught in Output workflows without losing failure context. Use when adding workflow try/catch logic, fallbacks, partial-failure handling, custom Error classes, or typed checks for errors thrown by steps and evaluators.
- Output Error Zod ImportGrowthX AI, IncFix Zod schema import issues in Output SDK workflows. Use when seeing "incompatible schema" errors, type errors at step boundaries, schema validation failures, or when schemas don't match between steps.
- Output Eval AuditGrowthX AI, IncAudit an existing eval suite for trustworthiness. Use when inheriting evals, suspecting evals miss real failures, or after significant pipeline changes.
- Output Eval Dataset DesignGrowthX AI, IncDesign diverse eval datasets using dimension-based variation. Use when bootstrapping eval datasets, when real traces are sparse, or when existing datasets miss edge cases.
- Output Eval Error AnalysisGrowthX AI, IncSystematically review workflow traces to identify failure modes before building evaluators. Use when starting an eval project, after significant pipeline changes, or when production quality drops.
- Output Eval Judge PromptGrowthX AI, IncDesign effective LLM judge .prompt files for evaluators. Use when creating judgeVerdict/judgeScore/judgeLabel prompts, or when existing judges produce unreliable results.
- Output Eval Validate JudgeGrowthX AI, IncValidate LLM judges against human labels using TPR/TNR metrics and train/dev/test splits. Use after writing a judge prompt to verify it agrees with human judgment.
- Output Meta Post FlightGrowthX AI, IncPost-flight validation for Output SDK workflow operations. Systematic verification of step completion, convention compliance, quality validation, and deliverable verification.
- Output Meta Pre FlightGrowthX AI, IncPre-flight validation checks for Output SDK workflow operations. Ensures conventions are followed, requirements are gathered, and quality gates are passed before workflow execution.
- Output Meta Project ContextGrowthX AI, IncComprehensive guide to Output.ai Framework for building durable, LLM-powered workflows orchestrated by Temporal. Covers project structure, workflow patterns, steps, LLM integration, HTTP clients, CLI commands, and the full inventory of available agents and skills.
- Output MigrateGrowthX AI, IncUpgrade a project between versions of the Output framework. Use when the user asks to upgrade, migrate, or move to a newer Output version. Detects the current @outputai/* version in the project, fetches the matching migration guide from docs.output.ai, applies the changes, and verifies the project still type-checks.
- Output Plan WorkflowGrowthX AI, IncUse when the user asks to create, build, generate, scaffold, or plan a new workflow. Orchestrates the full planning process including architecture, steps, prompts, evaluators, and testing strategy using specialized subagents.
- Output Services CheckGrowthX AI, IncVerify Output SDK development services are running. Use when debugging workflows, starting development, encountering connection errors, services may be down, or when you see "ECONNREFUSED" or timeout errors.
- Output Workflow ListGrowthX AI, IncList all available Output SDK workflows in the project. Use when discovering what workflows exist, checking workflow names, exploring the project's workflow structure, or when unsure which workflows are available to run.
- Output Workflow ResetGrowthX AI, IncRe-run an Output SDK workflow from after a specific completed step, creating a new run that replays up to that point and re-executes subsequent steps. Use when iterating on a later step's prompt or logic without re-running the entire workflow, or when recovering from a failure that only affects steps after a known-good point.
- Output Workflow ResultGrowthX AI, IncGet the result of an Output SDK workflow execution. Use when retrieving the output of a completed workflow, getting the return value, or checking what a workflow produced after async execution.
- Output Workflow RunGrowthX AI, IncExecute an Output SDK workflow synchronously and wait for the result. Use when running a workflow and needing immediate results, testing workflow execution, or getting the output directly in the terminal.
- Output Workflow Runs ListGrowthX AI, IncList Output SDK workflow execution history. Use when finding failed runs, reviewing past executions, identifying workflow IDs for debugging, filtering runs by workflow type, or investigating recent workflow activity.
- Output Workflow StartGrowthX AI, IncStart an Output SDK workflow asynchronously without waiting for completion. Use when starting long-running workflows, getting a workflow ID for later monitoring, running workflows in the background, or executing multiple workflows in parallel.
- Output Workflow StatusGrowthX AI, IncCheck the status of an Output SDK workflow execution. Use when monitoring a running workflow, checking if a workflow completed, or determining workflow state (RUNNING, COMPLETED, FAILED, TERMINATED).
