Code Mode Compare

See if stock covers an open order. The model writes one program that calls both lookups and subtracts.

code-modetools+3

Tool API Context

Pass arbitrary context from generateText/streamText to tool execution via experimental_context. Access context in tool execute functions for dynamic behavior.

aitools+5

Create 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.

aitools+8

Tool Input Lifecycle Hooks

Explore tool input lifecycle hooks: onInputStart, onInputDelta, and onInputAvailable. See how to track tool input generation in real-time during streaming.

aitools+7

Preliminary Tool Results

Return preliminary tool results using async iterables. Stream status updates during tool execution before the final result is available.

aitools+6

Tool Call Repair

Repair invalid tool calls using experimental_repairToolCall. Fix schema validation errors without requiring additional steps that pollute message history.

aitools+6

Call Options: prepareCall

Dynamically 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.

aiagents+7

Tool Context: experimental_context

Inject request-scoped context (user identity, database handles, session) into ToolLoopAgent tools via experimental_context, so the model never supplies sensitive identity in tool inputs.

aiagents+7

Loop Control: stopWhen

Demonstrate ToolLoopAgent loop control with stopWhen. Covers stepCountIs, hasToolCall, combined conditions, and a custom StopCondition with step timeline visualization.

aiagents+7

PrepareStep: Trim Message History

Demonstrate ToolLoopAgent prepareStep for trimming long message history. Pre-seeded 24-message conversation shows context compression on the first run with per-step trim telemetry.

aiagents+6

Structured Agent Output: Output.array

Demonstrate structured agent outputs using ToolLoopAgent with Output.array. Returns structured array output with element schema for predictable, type-safe responses.

aiagents+5

Structured Agent Output: Output.choice

Demonstrate structured agent outputs using ToolLoopAgent with Output.choice. Constrain agent outputs to predefined choices for predictable, type-safe responses.

Jev Action Gate

One command at a time. It passes the gate only when a Jev boolean clears 0.90.

Jev Best-of-N Judge

Three prepared replies sit on the table. A Jev choice lifts the winner only when its probability clears 0.70.

Jev Composite Scorecard

Score a pull request description with three atomic Jev score questions, then combine the answers with weights in code.

Jev Confidence Router

Four trays are on the table. A message flies to a team only when confidence and the selected probability both clear their floors.

Jev Email Tags

Tag a closed inbox with one Jev boolean per tag. A stamp lands only when its probability clears a floor.

Jev Evals

Run a rubric eval suite with jev-evals: one Jev call per case answers every rubric, and a baseline diff catches fractional regressions.

jevjev-evals+5

Jev Infinite FAQ

A 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.

Jev Loop Breaker

Look up facts one step at a time. Stop when Jev is at least 90% sure the notes answer the task, or after 3 lookups.

Jev Memory

Long-term agent memory with three Jev gates. Keep durable facts, recall what fits a token budget, and evict what went stale. Nothing is rewritten.

Jev Output Verifier

Write an answer, then show it only if Jev is at least 90% sure it actually answers the question. If not, rewrite once.

Jev Search Filter

Filter a closed catalog with one Jev boolean per item. Matches rise out of the pile when their probability clears a floor.

Jev Sub-agent Delegation

Pick one specialist with a Jev choice, then run only that agent when confidence and selected probability both clear their floors.

Jev Table Query

Filter or sort a closed table with one Jev question per row. A column name never leaves the app.

Jev Tool Permissions

Prune 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.

jevevaluation+7

Jev + Web Context

Exa finds live evidence, Jev answers the same question with and without it, and leave-one-out weights show what each source changed.
