TypeScript half of AIC-3598. The spec is in launchdarkly/ai-sdks-monorepo#91 (TESTING.md §5.3, §1.4, A.21). The Python half is launchdarkly/python-ai-sdk#218.

Changes

  • toolHandlers on the handler contract. ProviderHandler.stream and createHandler's input types took Record<string, any>. They now take Record<string, ToolHandlerFn | NativeTool>, which matches the blocking call signature and what apps already pass.
    • The union is the real contract, not functions only: offline evaluations (evaluations-runner.ts) pass the trajectory recorder's map to the handler without wrapToolHandlers, so a NativeTool arrives unwrapped.
    • Five handlers typed the map narrower, which the old any hid: claude-agents, claude-messages, langchain-agents, litellm-messages and openai-messages. They now accept the union.
    • Runtime behavior is unchanged, except in claude-agents' MCP tool executor. It now guards with typeof handler !== 'function', so a raw NativeTool gets the "No handler registered" error instead of handler is not a function. There's a test, and it fails without the fix.
  • @langchain/anthropic is declared by @launchdarkly/ai-langchain-agents as an optional peer plus a devDependency, the same pattern as @langchain/aws. The package dynamically imports it for Anthropic nodes. toolHandlers on the app-facing API was already typed.
  • zod is declared by @launchdarkly/ai-langchain-agents (^4.4.3, like its siblings). native-graph.ts imports it statically and was getting it through LangChain.
  • Packaging check, yarn check:packaging, added to the CI build job:
    • It fails when a package's built dist imports a package it doesn't declare, static or dynamic.
    • It then packs every workspace, installs all the tarballs into one empty project, and loads every exports subpath through both require() and import().
    • The scan has unit tests (yarn test:check-packaging). It found the zod gap above.
  • README documents the 1.0 rule: from 1.0.0, every package is released at the same version.

Breaking (the reason for the !)

ProviderHandler.stream's declaration changed, so scripts/api-breaking.mjs will flag it. A custom handler whose stream typed toolHandlers narrower than the union no longer type-checks. Before 1.0 the ! bumps the minor version, and AIC-3673 cuts 1.0 next. If owners judge it compatible, api-compatible is the alternative.

Checks

  • yarn build, yarn typecheck (0 errors), yarn code:check, yarn sherif
  • yarn api:check (only ai-server.api.md changed, the stream line) and yarn api:surface
  • yarn test: every workspace passes
  • yarn check:packaging: 14 packages declare every import, and all 16 entry points load
  • yarn.lock is unchanged

Known, out of scope

  • @langchain/anthropic@1.5.1 (the pinned dev version, as in langchain-messages) asks for @langchain/core@^1.2.1, while the lockfile resolves 1.1.49. That predates this change.
  • In both SDKs, claude-agents recognises a native tool only through the tracking stub's NATIVE_TOOL_KEY. On the offline evaluations path a raw NativeTool is therefore not wired to Claude's built-in tool. That's an evaluations behavior, so it's left for a follow-up.

🤖 Generated with Claude Code

Note

Overview
Tightens the public handler contract so toolHandlers is consistently Record<string, ToolHandlerFn | NativeTool> on blocking and streaming paths (replacing Record<string, any> on ProviderHandler.stream and internal handler helpers). Provider packages that narrowed the map are aligned, and claude-agents MCP execution now rejects unwrapped NativeTool values (offline evaluations) with the same “no handler” error instead of calling a non-function.

Packaging and release hygiene: adds yarn check:packaging (plus unit tests and CI after full build) to flag undeclared imports in built dist and to verify packed tarballs install and every export loads via require() and import(). @launchdarkly/ai-langchain-agents declares missing zod and optional peer @langchain/anthropic for its dynamic Anthropic import. README documents lockstep versioning from 1.0.0.

Breaking: ProviderHandler.stream's toolHandlers type changed; custom handlers with a narrower stream signature may need updates.

fix(AIC-3598)!: type toolHandlers on the handler contract; declare @l…
6f497eb 
…angchain/anthropic

- ProviderHandler.stream and createHandler's inputs take
  Record<string, ToolHandlerFn | NativeTool> instead of Record<string, any>,
  matching the blocking call signature and the type apps already pass.
  Offline evaluations hand a NativeTool to the handler unwrapped, so the
  union is the real contract, not functions only.
- Handlers that typed the map narrower (claude-agents, claude-messages,
  langchain-agents, litellm-messages, openai-messages) now accept the
  union. claude-agents' MCP tool executor guards with typeof, so a raw
  NativeTool gets the "No handler registered" error, not a TypeError.
- @launchdarkly/ai-langchain-agents declares @langchain/anthropic as an
  optional peer (it dynamically imports it for Anthropic nodes), like
  @langchain/aws.

Breaking: a custom handler whose stream() typed toolHandlers narrower
than the union no longer type-checks.

fix(AIC-3598): check that packed packages install and load; declare zod
dd78326 
- scripts/check-packaging.mjs (yarn check:packaging, run in the CI build
  job) fails when a package's built dist imports a package it does not
  declare, static or dynamic, then packs every workspace, installs all the
  tarballs into one empty project, and loads every exports subpath through
  require() and import(). The workspace tests cannot catch either: the
  workspace installs every package's dependencies at once.
- The scan found @launchdarkly/ai-langchain-agents importing zod without
  declaring it; it now depends on zod ^4.4.3 like its siblings.
- README: document the 1.0 versioning rule (lockstep per language).

[1.0.0](https://github.com/launchdarkly/js-ai-sdk/compare/@launchdarkly/ai-typesafe-0.2.0...@launchdarkly/ai-typesafe-1.0.0)
(2026-10-30)


### ⚠ BREAKING CHANGES

* **client:** conversation content is now captured on spans by default.
To keep it off, call configure({ options: { captureContent: false } })
once at startup.
* **client:** createHandler returns a new wrapper function rather than
adding providesFor to the function you pass and returning that same
function. Use the handler createHandler returns; the function you passed
in no longer carries providesFor.

### Features

* **client:** capture conversation content on spans by default and add
configure()

### Bug Fixes

<!-- CURSOR_SUMMARY -->

> [!NOTE]
> **Overview**
> This **release-please** PR cuts **1.0.0** for every workspace package
(`@launchdarkly/ai-server`, `@launchdarkly/ai-node`, provider adapters,
`@launchdarkly/ai-otel`, `@launchdarkly/ai-typesafe`) by updating
`.release-please-manifest.json`, each `package.json` / `src/version.ts`,
and adding **1.0.0** changelog sections. Provider packages bump their
`@launchdarkly/ai-server` dependency to **^1.0.0**.
> 
> The release notes bundled here flag **breaking** upgrades integrators
must handle: **`configure()`** with **conversation content on spans by
default** (opt out via `captureContent: false`); **`createHandler`** now
returns a **new wrapper** instead of mutating the passed function;
renamed factories (**`*MessagesHandler`**,
**`createOpenAIAgentsHandler`**); **`LaunchDarklySkillStore`** (was
`FDv2SkillStore`); **Evaluations promoted to core** with offline
export/trace and threshold behavior changes; telemetry
**`launchdarkly.project_id`** (was `highlight.project_id`); richer
**`feature_flag`** span events; and **SEC-9507** tool scoping (native
tools and handlers only see tools on the active variation).
