Released .NET packages also use `Microsoft.CodeAnalysis.PublicApiAnalyzers` to make source-level public API changes visible during builds. The `PublicAPI.*.txt` files use `#nullable enable` so nullability annotations are tracked as part of the public API surface. When adding, changing, or removing public APIs in a released package, update the package's `PublicAPI.Unshipped.txt` file with the analyzer-provided entries and include that change in your PR. The build will fail if public API changes are not reflected in the baseline files.
+If local or CI builds report Public API Analyzer warnings or errors, handle each diagnostic separately:
+
+- `RS0016` reports a newly exposed public API that is missing from the baseline. The preferred fix is to use the analyzer code fix on the affected code symbol to add the missing API entry automatically. Alternatively, run `dotnet format` for `RS0016` from the repository root:
+
+ ```powershell
+ dotnet format .\dotnet\agent-framework-dotnet.slnx analyzers --diagnostics RS0016
+ ```
+
+- `RS0017` reports that a declared public API was deleted. Restore the API if the deletion was accidental; otherwise, record the removed signature in the package's `PublicAPI.Unshipped.txt` file with the `*REMOVED*` prefix by using the corresponding code fix, or the following dotnet format script:
+
+ ```powershell
+ dotnet format .\dotnet\agent-framework-dotnet.slnx analyzers --diagnostics RS0017
+ ```
+
After a release, the `Promote Shipped APIs` workflow moves entries from `PublicAPI.Unshipped.txt` to `PublicAPI.Shipped.txt` and opens or updates a promotion PR. Publish builds fail if released packages still contain unshipped public API entries.

### Phase 3: Core Vector Store Abstractions
**Goal:** Establish all vector store types, enums, the decorator, collection definition, and base classes.
**Mergeable:** Yes â adds new abstractions, no breaking changes.
+**Feature stage:** Experimental (`VECTOR_STORES`).
-#### 3.1 â Vector store enums and field types in `_vectors.py`
-- `FieldTypes` enum: `KEY`, `VECTOR`, `DATA`
-- `IndexKind` enum: `HNSW`, `FLAT`, `IVF_FLAT`, `DISK_ANN`, `QUANTIZED_FLAT`, `DYNAMIC`, `DEFAULT`
-- `DistanceFunction` enum: `COSINE_SIMILARITY`, `COSINE_DISTANCE`, `DOT_PROD`, `EUCLIDEAN_DISTANCE`, `EUCLIDEAN_SQUARED_DISTANCE`, `MANHATTAN`, `HAMMING`, `DEFAULT`
-- No `SearchType` enum â use `Literal["vector", "keyword_hybrid"]` instead, per AF convention of avoiding unnecessary imports
+#### 3.1 â Vector store literal aliases and field types in `_vectors.py`
+- `FieldTypes`: `Literal["key", "vector", "data"]`
+- `IndexKind`: literal alias covering `hnsw`, `flat`, `ivf_flat`, `disk_ann`, `quantized_flat`, `dynamic`, and `default`
+- `DistanceFunction`: literal alias covering the supported similarity and distance functions
+- `SearchType`: `Literal["vector", "keyword_hybrid"]`
- `VectorStoreField` plain class (not Pydantic)
- `VectorStoreCollectionDefinition` class (not Pydantic internally, but supports Pydantic models as input)
-- `SearchOptions` plain class â includes `score_threshold: float | None` for filtering results by score (see note below)
- `SearchResponse` generic class
-- `RecordFilterOptions` plain class
+- `SearchResults` generic result container
+- Explicit keyword arguments on `get()` and `search()` instead of options classes
- `DISTANCE_FUNCTION_DIRECTION_HELPER` dict
#### 3.2 â `@vectorstoremodel` decorator
- Port from SK, works with dataclasses, Pydantic models, plain classes, and dicts
+- Plain classes can declare `VectorStoreField` metadata on annotated `__init__` parameters, matching `@tool`
- Sets `__vectorstoremodel__` and `__vectorstoremodel_definition__` on the class
- Remove SK-specific `kernel` prefix (`__kernel_vectorstoremodel__` â `__vectorstoremodel__`)
-#### 3.3 â Serialization/deserialization protocols
-- `SerializeMethodProtocol`, `ToDictFunctionProtocol`, `FromDictFunctionProtocol`, etc.
-- Port the record handler logic but without Pydantic base class â use plain class or ABC
+#### 3.3 â Registered model codecs
+- `register_vectorstoremodel` registers one collection definition and encoder/decoder pair per model type
+- `@vectorstoremodel` creates the definition and registers msgspec-backed default codecs
+- Dictionary records provide their collection definition directly
+- DataFrames and other row containers convert to sequences of row mappings before using the batch API
+- Custom encoder and decoder callbacks can be overridden independently
+- Array-like values such as NumPy arrays serialize through their `tolist()` method without a NumPy dependency;

īģŋ# Hosted-Workflow-Resilient-Long-Running
A deterministic countdown workflow that demonstrates resilient background execution. Each number is
-one workflow output item. If the process stops, AgentServer restores the last response snapshot and
-the workflow resumes from the exact workflow checkpoint ID recorded in that snapshot.
+one workflow output item. The workflow calls a separate idempotent HTTP service before emitting each
+number. If the process stops, AgentServer supplies its saved response and MAF resumes the workflow
+from the checkpoint referenced by that response.
-For an input such as `Count down from 6`, the final message outputs are:
+> **Local demonstration only.** This sample was prepared for
+> [`Using-E2E-Resilience`](../Using-E2E-Resilience/) to demonstrate workflow recovery after a crash or
+> graceful shutdown. The countdown only makes step recovery visible, and the SQLite service simulates
+> an operation to illustrate how repeated calls avoid duplicate records. Neither represents a real
+> business scenario. This workflow, its HTTP client, and the service are not intended for production
+> use or deployment to Foundry.
+
+The input must be a single message containing integer text. The start executor adds ten so the E2E
+has some progress to interrupt. With input `10`, a normal run emits:
```text
-6
-5
-4
-3
-2
+20
+19
+...
+11
+10
+...
1
-Countdown complete.
```
-The exact list makes recovery errors visible. A missing item means response state advanced beyond
-workflow state. A repeated item means the workflow resumed before the response snapshot boundary.
+At zero, the workflow terminates without a visible completion message. A recovered stream can
+include repeated text; this is separate from whether the service created duplicate operation records.
## Workflow
| Executor | Behavior |
| --- | --- |
-| `start` | Reads the first positive integer from the request. |
-| `countdown` | Waits, yields the current number, decrements it, and sends it back to itself. |
-| `complete` | Yields `Countdown complete.` after the counter reaches zero. |
+| `start` | Parses the single text input as an integer, adds ten, and sends it to `countdown`. |
+| `countdown` | Waits one second, calls the idempotent service, yields the returned number, and sends the decremented number to itself. |
+| `complete` | Receives an empty string when the count reaches zero and ends the workflow. |
All executor IDs and the workflow agent ID are stable so a replacement process reconstructs the same
workflow topology.
+## Idempotent operations
+
+The countdown calls `IdempotentServiceClient` from `Hosted_Shared_Contributor_Setup`. The
+[`Using-E2E-Resilience`](../Using-E2E-Resilience/) executable hosts the backing Kestrel service in a
+separate process when started with `--idempotent-service`. Only that service accesses SQLite.
+
+The service uses `(scope, operation_id)` as the primary key. The count is the operation ID. The first
+call creates a row containing its result:
+
+```text
+Operation Crash/10 executed.
+```
+
+If recovery executes the same countdown step again, the insert leaves that row unchanged and the
+service reads and returns its stored result:
+
+```text
+Duplicate operation Crash/10 ignored.
+```
+
+Configure the service with `IDEMPOTENT_SERVICE_ENDPOINT` and identify the logical operation group
+with `IDEMPOTENT_OPERATION_SCOPE`. Keep the scope unchanged across recovery attempts. Use a different
+scope for an unrelated run, otherwise the same counts intentionally reuse the previous results.
+
+The service can complete an operation before the workflow's progress is confirmed. A crash or
+shutdown during that interval can cause the step to be invoked again. The stable key protects the
+database operation, not the execution of the workflow step or the text displayed by a client.
+For a real email, payment, or API write, the downstream service must enforce equivalent idempotency.
+Simply placing that external call beside a SQLite insert would not make the two actions atomic.
+
## Recovery boundary

+by AgentServer, not the client's accumulated text.
+
+Workflow checkpoints, AgentSession storage, response storage, and the replay log are not one

+therefore rerun unconfirmed work. A later `response.in_progress` event carries replacement response

+The E2E reports the count rather than asserting it. The shutdown path exercises `IsShutdownRequested`
+and recovery deferral.

-The E2E creates a MAF client agent through `AIProjectClient.AsAIAgent(model, instructions)`. It
-enables `AgentRunOptions.AllowBackgroundResponses`, consumes `AgentResponseUpdate` values, saves the
-latest non-null `ResponseContinuationToken`, and supplies that token after the replacement server
-starts. It does not implement the Responses HTTP or SSE protocol itself.
-
-The demonstration uses one MAF client agent and one agent session for three calls:
-
-1. Starts the hosted workflow server as a child process.
-2. Creates a stored background streaming response through the MAF agent.
-3. Prints countdown messages as MAF streaming updates arrive.
-4. Waits until the matching workflow and response checkpoint is durable.
-5. Force-kills the server process tree.
-6. Starts a replacement server over the same AgentServer state.
-7. The second call reconnects with the sequence-aware continuation token and prints only newly
- recovered messages.
-8. The third call uses the same agent and session with the same response ID but no sequence cursor,
- replaying the entire stream from the start.
-9. The E2E verifies that the client accumulator and cursor-free replay contain the same complete
- countdown.
+īģŋ# Using-E2E-Resilience
-## Run
+This local E2E runs
+[`Hosted-Workflow-Resilient-Long-Running`](../Hosted-Workflow-Resilient-Long-Running/)
+through two recovery scenarios:
-Run from the repository root:
+1. `Crash`, which terminates the hosted workflow process abruptly.
+2. `Shutdown`, which follows the graceful shutdown path and defers the response for recovery.
-```powershell
-dotnet run --project dotnet\samples\04-hosting\FoundryHostedAgents\responses\Using-E2E-Resilience
-```
+> **Local demonstration only.** The E2E, countdown workflow, HTTP client, and SQLite service exist only
+> to demonstrate recovery after a crash or graceful shutdown. The countdown makes step recovery
+> visible, and the database insert is a simulated operation; no real email, payment, or other external
+> action is performed. This is not a real business scenario or a template for production use or
+> deployment to Foundry.
+
+## Three processes
+
+The E2E uses three processes while each scenario is running:
+
+| Process | Responsibility |
+| --- | --- |
+| `Using-E2E-Resilience` | Drives the scenario and consumes the recovered stream. |
+| `Hosted-Workflow-Resilient-Long-Running` | Runs the resilient countdown workflow. |
+| `Using-E2E-Resilience --idempotent-service` | Runs `IdempotentService` on Kestrel and stores operations in SQLite. |
+
+The idempotent service is a class inside this sample, not a separate project or demo. The E2E
+launches another instance of its own executable with `--idempotent-service`. That process runs only
+the service, not the Crash and Shutdown scenarios, and remains running while the hosted workflow
+process is replaced.
-The E2E program starts the first server, ends it abruptly, starts the replacement server with the
-same durable state, and ends the replacement when the verification completes. A separately running
-local server may remain open: the E2E uses a random port, isolated Debug binaries, and an isolated
-AgentServer state directory.
+Both the hosted workflow and the E2E use `IdempotentServiceClient` from
+`Hosted_Shared_Contributor_Setup`:
-No Azure project, model deployment, credentials, or second terminal is required.
-The E2E builds the server in Debug into an isolated temporary directory, so it does not reuse or
-overwrite the binaries of a separately running local server.
+1. The hosted workflow posts operations to the idempotent service.
+2. The idempotent service stores them in SQLite.
+3. The E2E queries the same service for the completed operation count.
-`AIProjectClient` requires an HTTPS endpoint before its bearer-token policy will run. The shared
-`LocalHttpSchemeRewriteHandler` presents HTTPS to that pipeline, then routes the request to the
-random loopback HTTP port at transport time. The handler rejects non-loopback targets.
+The workflow calls the service for every countdown value. The service stores each operation once
+using `(scope, operation_id)` as the SQLite primary key. If recovery repeats a workflow step, the
+service returns the existing result instead of creating another row.
-Example:
+## Current flow
+
+`Program.cs` sets `interruptNumberMessage` to `"10"`. The hosted workflow adds ten to that numeric
+input, so the countdown starts at 20 and the E2E interrupts it when it receives `10`.
+
+1. Build the hosted server and start the idempotent service and hosted server on separate loopback ports.
+2. Start a streaming background response. Read its first update and save the continuation token.
+3. Dispose that initial stream enumerator. This closes the client stream, not the accepted background operation.
+4. Open a second stream with the token and interrupt the hosted process at the selected count.
+5. Start a replacement hosted process with the same workflow state, service endpoint, and operation scope.
+6. Open a third stream using the original token, then query the service for the completed operation count.
+
+The recovered stream is consumed independently of the second request. The client displays all text
+updates and labels repeated text within that third request. It does not execute operations or
+remove duplicates. With the current input, the expected database count is 20. The E2E prints the
+returned count; it does not assert the count or the exact stream sequence.
+
+## Why idempotency matters
+
+An operation can finish at the service before the workflow's progress is durably confirmed. If the
+hosted process stops during that interval, recovery may execute the step and call the service again.
+The service's primary key makes the repeated call return the saved result without adding another row:
```text
-[1/7] Starting the first server process...
-[2/7] Starting the background countdown...
- before > 20
- before > 19
- before > 18
-...
-[4/7] Force-killing the first server process...
-[5/7] Starting a replacement server over the same durable state...
-[6/7] Reconnecting to the response stream...
- recovered > 10
- recovered > 9
-...
- recovered > Countdown complete.
-
-[7/7] Replaying from the start without a sequence cursor...
- replayed > 20
- replayed > 19
-...
- replayed > Countdown complete.
-
-Client retained countdown updates: 20
-Replay countdown updates: 20
-
-PASS: crash recovery completed with ordered output and no missing or duplicated items.
+Operation Crash/10 executed.
+Duplicate operation Crash/10 ignored.
```
-## Options
+Those are service log messages. Repeated text in the client stream can come from replaying old events
+or running an unconfirmed step again, so repeated text alone does not prove a second service effect.
+The timing of interruption determines whether the step must run again.
-```powershell
-dotnet run --project dotnet\samples\04-hosting\FoundryHostedAgents\responses\Using-E2E-Resilience -- `
- --target 30 `
- --crash-after-count 12 `
- --delay-seconds 1
-```
+**Workflow recovery, stream replay, and service idempotency have different jobs.** Checkpoints restore
+workflow progress. Replay lets a client receive stored events again. Idempotency protects the
+service's operation from being applied twice. Neither replay nor a checkpoint undoes an email or
+payment already performed. Real downstream services must enforce that protection themselves.
-| Option | Default | Meaning |
+## Internal service mode
+
+The E2E starts service mode automatically with a random loopback address in `ASPNETCORE_URLS` and an
+isolated SQLite file in `IDEMPOTENT_SERVICE_DATABASE_PATH`. Both are preserved while the hosted
+workflow restarts. At the end, the E2E stops the service and removes temporary state on success.
+
+Crash and Shutdown use separate temporary databases. Within each scenario, the service and its
+database remain alive across both hosted process lifetimes. Failed scenarios retain their files and
+print the paths for investigation; successful cleanup is best effort.
+
+| Method | Path | Purpose |
| --- | --- | --- |
-| `--target` | `20` | First countdown value. Must be at least 2. |
-| `--crash-after-count` | Half the target | Number of completed countdown messages before the crash. |
-| `--delay-seconds` | `1` | Delay between countdown steps. |
+| `GET` | `/readiness` | Reports that the service is ready. |
+| `POST` | `/operations/{scope}/{operationId}` | Creates an operation or returns its stored result. |
+| `GET` | `/operations/{scope}/count` | Returns the number of completed operations in the scope. |
+
+## What normally triggers each path
+
+Foundry sends `SIGTERM` when it intentionally stops a hosted agent container and can provide a
+graceful shutdown window. This can happen during managed lifecycle operations such as session
+compute deprovisioning, scale-in, or redeployment.
+
+An abrupt crash provides no shutdown window. Typical examples include an application process crash,
+a forced process termination, and an out-of-memory kill.
+
+The local Shutdown scenario requests `StopAsync()` on the AgentServer task service, then stops the
+web host. It exercises the shutdown signal without sending an OS signal on Windows. It does not
+guarantee that a partially completed workflow step will never run again.
-Server output is redirected to a temporary log whose path is printed at startup. Each run uses a
-random local port and an isolated AgentServer state directory. Successful runs delete their durable
-state. Failed runs retain state and print its path for investigation.
+See [the hosted agent runtime contract](https://learn.microsoft.com/azure/foundry/agents/concepts/hosted-agent-contract)
+and [recovery guidance](https://learn.microsoft.com/azure/foundry/agents/how-to/recover-long-running-work).
-The second call's continuation token resumes after the last update consumed before the crash.
-Previously consumed countdown messages are retained in the client accumulator and are not streamed
-again. Only work after the durable checkpoint appears as `recovered`.
+## Run
+
+No Azure project, model deployment, credentials, or second terminal is required. The E2E builds the
+hosted workflow server and starts both server processes automatically.
+
+From the repository root:
+
+```powershell
+dotnet run --project dotnet\samples\04-hosting\FoundryHostedAgents\responses\Using-E2E-Resilience
+```
-For the third call, the E2E derives another valid `ChatClientAgent` continuation token whose inner
-Responses token contains the same response ID without a sequence number. That call prints every
-persisted stream item as `replayed`.
+To change the demonstration, edit `interruptNumberMessage` in `Program.cs`. `--idempotent-service`
+selects the internal service process instead of running the E2E scenarios.

+
+ A single Agent Framework message can interleave assistant content (text,
+ function_call) with one or more function_result (tool) contents -- for example a
+ parallel tool-call batch or a finalized turn. AG-UI needs each function_result as
+ its own ``tool`` message. ``_sanitize_tool_history`` resets its pending-call set on
+ every non-tool message, so a result is dropped as orphaned whenever an assistant
+ message lands between a call and that call's result. Four ordering rules keep the
+ transcript provider-valid:
+
+ * A ``function_call`` must precede its matching result, so a pending assistant
+ segment that carries tool calls is flushed (together with any buffered text) right
+ before the result.
+ * A text-only segment is NOT flushed before a result. Such text is deferred and
+ emitted after the results instead.
+ * A new assistant segment is NOT flushed while earlier emitted calls are still
+ awaiting their results. For ``[call A, call B, result A, call C, result B,
+ result C]``, flushing ``assistant(C)`` before ``result B`` would separate the
+ still-open call B from its result; deferring it yields ``[assistant(A,B), tool(A),
+ tool(B), assistant(C), tool(C)]``.
+ * A result whose own call is still buffered (not yet emitted) is QUEUED rather than
+ emitted, because emitting it would leave it ahead of its call. For
+ ``[call A, call B, result A, call C, result C, result B]`` the queued ``result C``
+ is held until ``assistant(C)`` is flushed, giving ``[assistant(A,B), tool(A),
+ tool(B), assistant(C), tool(C)]``.
+
+ ``unresolved_call_ids`` is owned by ``agent_framework_messages_to_agui`` and carried
+ across the whole conversion, not rebuilt per message: a call emitted by an earlier
+ message stays open until its result is emitted, so a later mixed message cannot slip
+ a new assistant segment between that call and its result (e.g. a prior
+ ``assistant(call A)`` followed by ``[call C, result A, result C]``).
+
+ The source message id is kept on the first emitted message; every additional
+ message gets an independent generated id. Deriving suffixes from the source id
+ (e.g. ``f"{base_id}-1"``) risks colliding with a legitimate id elsewhere in the
+ history, which would let id-keyed clients re-collapse the split messages.

- **`allowed_tools`** (constructor arg on all `MCPTool` subclasses) - Restricts exposed MCP tools by raw remote MCP tool identity. Prefixed local names remain accepted only when the raw remote name already matches its normalized form; normalized/local aliases do not authorize a different raw remote name. If multiple raw remote tool names map to the same local function name, tool loading raises `ToolExecutionException` instead of first-one-wins shadowing.
- **Progressive MCP disclosure** (`use_progressive_disclosure`, `always_load`) - When enabled on any `MCPTool` subclass, the initial model-facing surface is loader tools (`list_mcp_tools` / `load_tool` / `unload_tool`, prefixed by `tool_name_prefix` when configured) plus allowed tools selected by `always_load` and tools loaded earlier on the same `MCPTool` instance. `list_mcp_tools` only reports tools that pass `allowed_tools`; filtered tools are not listed or loadable. Loader tool names are reserved in progressive mode: remote MCP tools whose local generated name collides with a loader name are omitted from the initial/listed surface, and explicit `load_tool` calls return a model-visible message pointing callers to `tool_name_prefix` or excluding the colliding tool. `load_tool` accepts one tool name or a list of tool names and uses `FunctionInvocationContext.add_tools(...)` so the selected generated MCP `FunctionTool`s become available on the next function-calling iteration while keeping existing approval mode, argument filtering, header-provider runtime kwargs, result parsing, OTel, and task behavior. `unload_tool` accepts one dynamically loaded tool name or a list of names and removes them from the live tool list and persisted progressive surface, but it does not remove tools configured in `always_load`. Invalid `always_load` entries are ignored like unmatched `allowed_tools` entries.
- **`additional_tool_argument_names`** (constructor arg on all `MCPTool` subclasses) - Opt extra argument names back into the allowlist. Accepts a `Sequence[str]` (applied to every tool) or a `Mapping[str, Sequence[str]]` keyed by **remote tool name**, where the reserved key `"*"` denotes global extras. It is configured only in user code at construction; there is **no per-call/runtime override**, so a model-issued tool call cannot change which names pass through â but note this constrains the *model*, not the *server*, which still widens the effective allowlist through its schema. To use a server that accepts `additionalProperties: true`, list the extra names here and then either (1) manually extend that tool's `inputSchema` (via the `.functions` list after connecting) so the model is prompted to supply them, or (2) supply the values yourself via `function_invocation_kwargs`. If a normal forwarded argument name is supplied by both the model and `function_invocation_kwargs`, the model-supplied value wins; `_meta` is the exception and only trusted runtime/caller metadata is used.
+- **`header_provider` request scoping** - When sharing an `http_client`, keep provider processing scoped to the originating `MCPStreamableHTTPTool` and strip injected headers from cross-origin redirects. The session exit stack removes its request hook after transport shutdown, including failed initialization or discovery, and closes framework-created HTTP clients. Failed discovery resets the connection and discovery flags and rolls back partial function/metadata additions. Framework-created sessions are discarded; constructor-supplied sessions remain caller-owned and reusable across cleanup, close, and reset.
+- **MCP lifecycle caller cancellation** - The lifecycle owner skips cancelled queued connect requests and waits for the caller to acknowledge successful setup. If the caller cancels before accepting a newly established connection, the owner tears it down before processing the next request. Cancelling a close waiter does not interrupt teardown, and cancelling a redundant connect does not discard a previously established session.
- **`function_invocation_kwargs` and MCP servers** - That dict is shared across every tool in the run, including every attached `MCPTool`, and any name in it reaches a server that declares a matching `inputSchema` property. `header_provider` does not mitigate this â it reads the kwargs without consuming them. To keep a credential out of tool arguments, source it outside `function_invocation_kwargs`: read a `ContextVar` inside the provider (this still allows a different value per request), configure a custom `http_client`, or use `env` for `MCPStdioTool`.
- **Sampling guardrails** (`sampling_callback`) - Passing `client=` advertises `SamplingCapability` so the server can send `sampling/createMessage`. Because remote servers are untrusted (confused-deputy risk), the default `sampling_callback` is **deny-by-default** and applies, in order: a per-session rate limit (`sampling_max_requests`, default `_DEFAULT_SAMPLING_MAX_REQUESTS`), an approval gate (`sampling_approval_callback`), and a `maxTokens` cap (`sampling_max_tokens`, default `_DEFAULT_SAMPLING_MAX_TOKENS`). The approval callback (constructor arg on all subclasses; exported type alias `SamplingApprovalCallback`) receives the raw `CreateMessageRequestParams`, may be sync or async, and must return truthy to approve. When it is `None` (the default) every sampling request is denied; pass `lambda params: True` to restore legacy auto-approve as an explicit opt-in. Requests and denials are logged at WARNING (content is not logged). The per-session counter resets in `_reset_session_state`.
- **`MCPTaskOptions`** (experimental, `MCP_LONG_RUNNING_TASKS` feature, **frozen**) - Per-tool-instance options controlling the SEP-2663 long-running task lifecycle. When the server advertises a tool with `execution.taskSupport == "required"`, `MCPTool.call_tool` transparently routes through `call_tool_as_task`, which sends an augmented `tools/call`, polls `tasks/get` until terminal, and reinterprets `tasks/result` as a normal `CallToolResult`. Instances are immutable; replace via `MCPTool.task_options = MCPTaskOptions(...)`. Fields:

-- **`AgentFileStore`** - Abstract async store backing the file-access harness. Implementations expose `write`, `read`, `delete`, `list_children`, `file_exists`, `search`, and `create_directory` over forward-slash relative paths. `list_children` returns the direct children (files and subdirectories, subdirectories first) as `FileStoreEntry` instances; `search` accepts a keyword-only `recursive` flag (default `False`) and, when `recursive=True`, walks all descendants and returns `file_name` values relative to the search directory.

The line-numbering contract lives on the base class: `split_lines` publishes the `\n`-only keepends split that every `line_number` addresses, `scan_content` is the numbering primitive both shipped stores report through, and `search` is now **concrete** â it asks the overridable `find_matching_files` hook which files to consider (superset semantics; a backend with a native index overrides it and prunes server-side) and then reads and numbers them itself. A store may still override `search` outright, but then it owns numbering: it must report `line_number` as a 1-based coordinate into `split_lines` of the content `read` returns. Nothing checks that at run time, so a store that numbers differently makes a later edit land on the wrong line silently.
- **`InMemoryAgentFileStore`** - Dict-backed store suitable for tests and lightweight scenarios.
- **`FileSystemAgentFileStore`** - Disk-backed store rooted under a configurable directory. Enforces relative-path normalization, root containment, and rejects symlink/reparse-point segments to prevent escape.

+- **`FileSearchResult`** / **`FileSearchMatch`** - `SerializationMixin` DTOs returned by `search`, carrying the matching file name, a context snippet, and the matching lines with 1-based line numbers. Implementers should report each matching line verbatim, including its own terminator, so it can be reused as a `file_access_replace_lines` `new_line`; the pattern itself is matched against the line with its whole terminator removed, so `^`/`$` anchor to the line's text on a CRLF file as they already did on an LF one. A custom store populates these DTOs from its own `search`; the verbatim text is a recommendation, but the line number is not â it must address `split_lines`.
- **`FileStoreEntry`** - `SerializationMixin` DTO returned by `list_children`, carrying an entry `name` and `type` (`"file"` or `"directory"`).
-- **`FileAccessProvider`** - `ContextProvider` that adds shared file-access tools (`file_access_write`, `file_access_read`, `file_access_delete`, `file_access_ls`, `file_access_grep`, `file_access_replace`, `file_access_replace_lines`) plus default usage instructions to each invocation. `file_access_ls` enumerates direct children (both files and subdirectories) as `{name, type}` entries with an optional `glob_pattern`, so the agent can walk the tree level by level; `file_access_grep` searches recursively from an optional base `directory` and returns relative `file_name` paths, scoped via an `fnmatch` `glob_pattern` (where `*` crosses `/`, e.g. `*.md`, `reports/*`). `file_access_replace` substitutes `old_string` with `new_string` (failing if not found, or if multiple matches and `replace_all` is false); `file_access_replace_lines` replaces whole 1-based lines with literal text (each `new_line` includes its own trailing newline; an empty `new_line` deletes the line, including its line break). All tools are registered with `approval_mode="always_require"` by default, so every file operation needs host approval. Pass `disable_write_tools=True` to advertise only the read-only tools. To run unattended you can disable approval at the source with `disable_readonly_tool_approval=True` (read, ls, grep) and/or `disable_write_tool_approval=True` (write, delete, replace, replace_lines), which register the affected tools with `approval_mode="never_require"`; alternatively, keep approval on and pass one of the static auto-approval rules to `ToolApprovalMiddleware` (via `auto_approval_rules`): `FileAccessProvider.read_only_tools_auto_approval_rule` approves only the read-only tools (read, ls, grep), while `FileAccessProvider.all_tools_auto_approval_rule` approves every file-access tool including the write tools. Both rules reject any call carrying a `server_label` so they stay scoped to this provider's local tools and never auto-approve a same-named hosted tool. The tool names are also exposed as class constants (`WRITE_TOOL_NAME`, `READ_TOOL_NAME`, `DELETE_TOOL_NAME`, `LS_TOOL_NAME`, `GREP_TOOL_NAME`, `REPLACE_TOOL_NAME`, `REPLACE_LINES_TOOL_NAME`).

Everything after the tab is verbatim, including the line's own terminator (which therefore doubles as the row separator), so a row's text can be fed straight back as a `file_access_replace_lines` `new_line` without losing a `\r\n`. Its line numbering comes from the same `_split_lines_keepends` split as `file_access_replace_lines` and as the stores in this package, so with one of those a number reported by grep addresses the same line in all three tools, including the trailing empty line of a newline-terminated file; grep itself runs through `AgentFileStore.search`, which must number by the same split but does not inherit it, so a store overriding `search` owns its numbering and nothing verifies it at run time.

This package contains the Microsoft Foundry integrations for Microsoft Agent Framework, including Foundry chat clients, preconfigured Foundry agents, Foundry embedding clients, and Foundry memory providers.
+## Evaluations
+
+`FoundryEvals` implements the provider-neutral `Evaluator` protocol with
+Microsoft Foundry's built-in and generated evaluators. Core owns `EvalItem`,
+local evaluation, and the `evaluate_agent()` / `evaluate_workflow()`
+orchestration functions; this package owns the Foundry Evals data mappings,
+wire serialization, submission, polling, and result parsing.
+
+Use `evaluate_agent()` for the common run-and-evaluate path:
+
+```python
+from agent_framework import evaluate_agent
+from agent_framework.foundry import FoundryEvals
+
+results = await evaluate_agent(
+ agent=agent,
+ queries=["What's the weather in Seattle?"],
+ evaluators=FoundryEvals(),
+)
+```
+
+For manual control, construct public `EvalItem` instances and pass them to
+`FoundryEvals.evaluate()`. The Foundry wire format is private to this package.
+`evaluate_traces()` and `evaluate_foundry_target()` provide Foundry-specific
+entry points for existing traces, response IDs, and registered targets.
+
## Concurrent reuse
A `FoundryChatClient` instance can be shared by concurrent asynchronous calls on the same event loop. Streaming,

+
+The output lists `web_search` and `web_fetch`, followed by their results, including source URLs and excerpts. Queries, requested URLs, objectives, and the session identifier are sent to Parallel when the calls run. The context manager closes the connection afterward.

+# Vector stores
+
+Vector stores accept multiple model styles so applications can keep the data
+representation that already fits their validation, memory, and interoperability
+needs. When you own a model, annotate a dataclass, Pydantic model, msgspec
+struct, or plain class. When another team or package owns it, register an
+explicit definition and codecs. Dictionaries use a collection-specific
+definition; DataFrames and other containers can convert to row dictionaries
+before calling the batch API.
+
+No database or credentials are needed for these examples.
+
+| File | Demonstrates |
+|------|--------------|
+| [`vector_store_models.py`](vector_store_models.py) | Choosing among owned models, third-party model registration, and loose dictionary definitions. |
+| [`optimized_data_formats.py`](optimized_data_formats.py) | Keeping NumPy vector fields and adapting pandas DataFrames to the batch record API. |
+
+The first section shows the two equivalent custom-codec registration forms.
+`@vectorstoremodel` derives the definition from annotations and registers it;
+`register_vectorstoremodel` accepts an externally constructed definition.
+Both produce the same internal model registration.
+
+The sample order is informed by a small benchmark on Apple Silicon with
+CPython 3.13. Each benchmark model had the same `id`, `text`, and `vector`
+fields. Results are medians of seven warmed runs:
+
+| Model style | 3-element vector | 1,566-element vector |
+|-------------|-----------------:|---------------------:|
+| Custom codecs | 2.60 Îŧs | 7.01 Îŧs |
+| Dictionary | 2.39 Îŧs | 6.60 Îŧs |
+| Plain class | 3.46 Îŧs | 12.26 Îŧs |
+| msgspec `Struct` | 3.03 Îŧs | 16.61 Îŧs |
+| Dataclass | 3.17 Îŧs | 16.81 Îŧs |
+| Pydantic | 5.52 Îŧs | 37.32 Îŧs |
+
+These results measure only the framework's internal record conversion path.
+They do not include database SDK conversion, network I/O,
+embedding generation, validation complexity, nested fields, alternate vector
+representations, or memory allocation. Custom codecs are especially favorable
+here because the benchmark codec returns the existing vector reference rather
+than copying it. The middle ordering also changes with vector size, so treat
+these timings as illustrative data, not a recommendation or performance
+guarantee.
+
+Array-like vector values, including NumPy arrays, are serialized through their
+`tolist()` method without making NumPy a core dependency. If a model must
+restore a NumPy array instead of a Python list, pass a custom `decoder` to
+`@vectorstoremodel` or `register_vectorstoremodel` and call `numpy.array` or
+`numpy.asarray` there.
+
+Run the sample from the `python` directory:

+Sample: Magentic Orchestration with Custom Manager Prompts
+
+The `StandardMagenticManager` drives planning, replanning, progress tracking, and the final
+answer with a set of built-in prompts. Every one of them can be replaced through
+`MagenticBuilder`, which is useful when the orchestration has to follow a house style, a
+domain vocabulary, or a fixed report format.
+
+Overridable prompts and the placeholders available to each one:
+
+| Builder argument | Placeholders | Used for |
+| ---------------------------------- | ---------------------------------- | --------------------------------- |
+| `task_ledger_facts_prompt` | `{task}` | Initial fact sheet |
+| `task_ledger_plan_prompt` | `{team}` | Initial plan |
+| `task_ledger_full_prompt` | `{task}`, `{team}`, `{facts}`, `{plan}` | Combined ledger shown to the team |
+| `task_ledger_facts_update_prompt` | `{task}`, `{old_facts}` | Fact sheet refresh on replan |
+| `task_ledger_plan_update_prompt` | `{team}` | New plan on replan |
+| `progress_ledger_prompt` | `{task}`, `{team}`, `{names}` | Per-round progress decision |
+| `final_answer_prompt` | `{task}` | Final synthesized answer |
+
+A prompt is formatted with `str.format`, so any literal brace in a custom prompt must be
+doubled (`{{`, `}}`). An override may omit any available placeholder, but any placeholder it
+uses must have a name listed above. `progress_ledger_prompt` is the one override to treat with
+care: its response is parsed as JSON, so a replacement must keep the same schema as the
+built-in prompt. This sample leaves it at the default and overrides the six prompts that shape
+the ledger and the final report. Note that the replan prompts have to be overridden alongside
+the initial ones: a stall makes the manager rebuild the fact sheet and the plan, and leaving
+the replan prompts at their defaults would silently drop the custom format mid-run.
+
+Prerequisites:
+- FOUNDRY_PROJECT_ENDPOINT must be your Microsoft Foundry Agent Service (V2) project endpoint.
+- FOUNDRY_MODEL must be set to your Azure OpenAI model deployment name.
+- Authentication via azure-identity. Use AzureCliCredential and run az login before executing the sample.
