Preserve the generic <code>tool_search_tool_result</code> block type in
streaming output and message payload conversion. The Anthropic API emits
this un-suffixed type for both tool search variants; previously only the
variant-suffixed names were allowlisted, so multi-turn conversations
using tool search still failed with INVALID_TOOL_RESULTS after a
client-tool round-trip.</li>

Round-trip the tool search server-tool result blocks
(<code>tool_search_tool_bm25_tool_result</code> /
<code>tool_search_tool_regex_tool_result</code>) through message
translation, mirroring <code>web_search_tool_result</code>. Without
this, a multi-turn conversation using the tool search tool fails on the
next request with <code>400 invalid_request_error … tool use … found
without a corresponding … tool_result block</code>, because the result
block was dropped from the assistant message (streaming capture) and on
re-send (<code>toolTypes</code> passthrough).</li>

- feat(anthropic): mark Anthropic provider errors as retryable or
not</p>
<p>Builds on <code>stampRetryable</code> in <code>@langchain/core</code>
so the retry middleware can tell a transient failure from a
deterministic one. Rate limits are marked retryable; context overflow,
invalid tool results, bad credentials, and unknown models non-retryable.
Anything else stays unmarked and retries as before.</p>
<p>Also forwards a per-call <code>maxRetries</code> to the retry loop,
so a surrounding retry loop such as <code>modelRetryMiddleware</code>
can take over instead of the two multiplying against each other.</p>
<p>Errors keep their original class, so <code>instanceof</code> against
the <code>@anthropic-ai/sdk</code> error types is unaffected.</p>

- feat(core): mark errors as retryable or not, and stop retrying the
ones that aren't</p>
<p>Retry middleware retried every failure up to <code>maxRetries</code>,
including deterministic ones like a bad API key or an unknown model.
Retries also nest, so a single such failure could cost dozens of API
calls.</p>
<p><code>@langchain/core/errors</code> adds <code>stampRetryable(error,
retryable)</code> and <code>getRetryable(error)</code>. Marking an error
leaves its class and shape untouched, so a provider SDK error can be
classified without breaking <code>instanceof</code>.
<code>getRetryable</code> returns <code>undefined</code> for errors
nobody classified, and both are exported so tool authors can mark their
own failures.</p>
<p><code>modelRetryMiddleware</code> and
<code>toolRetryMiddleware</code> now respect the mark by default, and
retries stop as soon as one is found rather than each layer spending its
own budget. Aborted calls, context overflow, and oversized payloads are
marked non-retryable out of the box.
Models accept a per-call <code>maxRetries</code> so a surrounding retry
loop can take over.</p>
<p><strong>Behavior change:</strong> errors marked non-retryable now
fail on the first attempt. Unclassified errors — including any from
third-party integrations or custom tools — retry exactly as before. Pass
<code>retryOn: () => true</code> to restore the old default. A custom
<code>onFailedAttempt</code> replaces the built-in handler and opts out
of marking.</p>

fix: apply [Symbol.hasInstance] method to all comparable properties

<p>We have some internal schemas that rely on
<code>z.instanceof()</code>. This uses a strict <code>instanceof</code>
check which can conflict if there are multiple versions of core
installed. This overrides the <a

method to use the same logic as <code>.isInstance()</code> to compare
objects at runtime.</p>

- feat(core): mark errors as retryable or not, and stop retrying the
ones that aren't</p>
<p>Retry middleware retried every failure up to <code>maxRetries</code>,
including deterministic ones like a bad API key or an unknown model.
Retries also nest, so a single such failure could cost dozens of API
calls.</p>
<p><code>@langchain/core/errors</code> adds <code>stampRetryable(error,
retryable)</code> and <code>getRetryable(error)</code>. Marking an error
leaves its class and shape untouched, so a provider SDK error can be
classified without breaking <code>instanceof</code>.
<code>getRetryable</code> returns <code>undefined</code> for errors
nobody classified, and both are exported so tool authors can mark their
own failures.</p>
<p><code>modelRetryMiddleware</code> and
<code>toolRetryMiddleware</code> now respect the mark by default, and
retries stop as soon as one is found rather than each layer spending its
own budget. Aborted calls, context overflow, and oversized payloads are
marked non-retryable out of the box.
Models accept a per-call <code>maxRetries</code> so a surrounding retry
loop can take over.</p>
<p><strong>Behavior change:</strong> errors marked non-retryable now
fail on the first attempt. Unclassified errors — including any from
third-party integrations or custom tools — retry exactly as before. Pass
<code>retryOn: () => true</code> to restore the old default. A custom
<code>onFailedAttempt</code> replaces the built-in handler and opts out
of marking.</p>

<p>We have some internal schemas that rely on
<code>z.instanceof()</code>. This uses a strict <code>instanceof</code>
check which can conflict if there are multiple versions of core
installed. This overrides the <a

- feat(openai): mark OpenAI provider errors as retryable or not</p>
<p>Builds on <code>stampRetryable</code> in <code>@langchain/core</code>
so the retry middleware can tell a transient failure from a
deterministic one. Timeouts and rate limits are marked retryable;
aborts, context overflow, invalid tool results, bad credentials, and
unknown models non-retryable. Anything else stays unmarked and retries
as before.</p>
<p>Also forwards a per-call <code>maxRetries</code> to the retry loop,
so a surrounding retry loop such as <code>modelRetryMiddleware</code>
can take over instead of the two multiplying against each other.</p>
<p>Errors keep their original class, so <code>instanceof</code> against
the <code>openai</code> SDK error types is unaffected.</p>
