Code Mode CompareSee if stock covers an open order. The model writes one program that calls both lookups and subtracts.Sep 2026
Tool API ContextPass arbitrary context from generateText/streamText to tool execution via experimental_context. Access context in tool execute functions for dynamic behavior.Nov 2025
Dynamic ToolCreate dynamic tools with runtime-generated schemas using dynamicTool. Demonstrates unit conversion tools where schema adapts based on conversion type (temperature, length, weight, currency) and supports dynamic model selection.Nov 2025
Tool Input Lifecycle HooksExplore tool input lifecycle hooks: onInputStart, onInputDelta, and onInputAvailable. See how to track tool input generation in real-time during streaming.Nov 2025
Preliminary Tool ResultsReturn preliminary tool results using async iterables. Stream status updates during tool execution before the final result is available.Nov 2025
Tool Call RepairRepair invalid tool calls using experimental_repairToolCall. Fix schema validation errors without requiring additional steps that pollute message history.Nov 2025
Call Options: prepareCallDynamically configure one ToolLoopAgent per request with callOptionsSchema and prepareCall. A customer-support agent rewrites instructions, gates tools, tunes reasoning effort, and injects RAG context based on account tier and urgency.Jun 2026
Tool Context: experimental_contextInject request-scoped context (user identity, database handles, session) into ToolLoopAgent tools via experimental_context, so the model never supplies sensitive identity in tool inputs.Jun 2026
Loop Control: stopWhenDemonstrate ToolLoopAgent loop control with stopWhen. Covers stepCountIs, hasToolCall, combined conditions, and a custom StopCondition with step timeline visualization.Jun 2026
PrepareStep: Trim Message HistoryDemonstrate ToolLoopAgent prepareStep for trimming long message history. Pre-seeded 24-message conversation shows context compression on the first run with per-step trim telemetry.Jun 2026
Structured Agent Output: Output.arrayDemonstrate structured agent outputs using ToolLoopAgent with Output.array. Returns structured array output with element schema for predictable, type-safe responses.Nov 2025
Structured Agent Output: Output.choiceDemonstrate structured agent outputs using ToolLoopAgent with Output.choice. Constrain agent outputs to predefined choices for predictable, type-safe responses.Nov 2025
Jev Action GateOne command at a time. It passes the gate only when a Jev boolean clears 0.90.
Jev Best-of-N JudgeThree prepared replies sit on the table. A Jev choice lifts the winner only when its probability clears 0.70.Sep 2026
Jev Composite ScorecardScore a pull request description with three atomic Jev score questions, then combine the answers with weights in code.Sep 2026
Jev Confidence RouterFour trays are on the table. A message flies to a team only when confidence and the selected probability both clear their floors.
Jev Email TagsTag a closed inbox with one Jev boolean per tag. A stamp lands only when its probability clears a floor.Sep 2026
Jev Entity ResolutionResolve messy card statement descriptors to the merchants behind them. Code blocks and vetoes, Jev answers one boolean per pair, and unsure matches wait for review.Oct 2026
Jev EvalsRun a rubric eval suite with jev-evals: one Jev call per case answers every rubric, and a baseline diff catches fractional regressions.Sep 2026
Jev Infinite FAQA FAQ whose last row is a live ask field. Jev opens a canned answer when it matches, or a short grounded answer becomes another row.Sep 2026
Jev Loop BreakerLook up facts one step at a time. Stop when Jev is at least 90% sure the notes answer the task, or after 3 lookups.Sep 2026
Jev MemoryLong-term agent memory with three Jev gates. Keep durable facts, recall what fits a token budget, and evict what went stale. Nothing is rewritten.Sep 2026
Jev Output VerifierWrite an answer, then show it only if Jev is at least 90% sure it actually answers the question. If not, rewrite once.Sep 2026
Jev Search FilterFilter a closed catalog with one Jev boolean per item. Matches rise out of the pile when their probability clears a floor.
Jev Semantic ClusteringDiscover themes in comments with no labels up front. Embeddings pick likely pairs, Jev answers one boolean per pair, and code does the grouping.Oct 2026
Jev Sub-agent DelegationPick one specialist with a Jev choice, then run only that agent when confidence and selected probability both clear their floors.Sep 2026
Jev Table QueryFilter or sort a closed table with one Jev question per row. A column name never leaves the app.Sep 2026
Jev Tool PermissionsPrune an agent's tool list before the model sees it. Allow and deny rules run first; Jev asks one relevance boolean per remaining tool in a single call.Sep 2026
Jev + Web ContextExa finds live evidence, Jev answers the same question with and without it, and leave-one-out weights show what each source changed.Sep 2026
