# `JidoGralkor.Actions.MemorySearch`
[🔗](https://github.com/elimydlarz/jido_gralkor/blob/main/lib/jido_gralkor/actions/memory_search.ex#L1)

ReAct tool the LLM can call to search long-term memory.

Calls `Gralkor.Client.recall/3`. `group_id` is sanitized from
`context[:agent_id]` and `session_id` is read from
`context[:session_id]` (planted by `JidoGralkor.Plugin` on
`ai.react.query`).

Short-circuits with an explicit non-result message when:

  * `session_id` is absent or blank (first query of a fresh agent,
    before the ReAct strategy committed a thread), or
  * `query` is blank — defensive against forced-tool-call paths
    (`tool_choice: memory_search`) where the LLM is required to
    invoke the tool but has nothing meaningful to search for.

Otherwise returns the memory block the server produced. Errors
propagate.

# `__action_metadata__`

Returns the Action metadata. Alias for to_json/0.

# `category`

Returns the category of the Action.

# `description`

Returns the description of the Action.

# `name`

Returns the name of the Action.

# `on_after_run`

Lifecycle hook called after Action execution.

# `on_after_validate_output`

Lifecycle hook called after output validation.

# `on_after_validate_params`

Lifecycle hook called after parameter validation.

# `on_before_validate_output`

Lifecycle hook called before output validation.

# `on_before_validate_params`

Lifecycle hook called before parameter validation.

# `on_error`

Lifecycle hook called when an error occurs.

# `output_schema`

Returns the output schema of the Action.

# `run`

Executes the Action with the given parameters and context.

The `run/2` function must be implemented in the module using Jido.Action.

# `schema`

Returns the input schema of the Action.

# `tags`

Returns the tags associated with the Action.

# `to_json`

Returns the Action metadata as a JSON-serializable map.

# `to_tool`

Converts the Action to an LLM-compatible tool format.

# `validate_output`

```elixir
@spec validate_output(map()) :: {:ok, map()} | {:error, String.t()}
```

Validates the output result for the Action.

## Examples

    iex> defmodule ExampleAction do
    ...>   use Jido.Action,
    ...>     name: "example_action",
    ...>     output_schema: [
    ...>       result: [type: :string, required: true]
    ...>     ]
    ...> end
    ...> ExampleAction.validate_output(%{result: "test", extra: "ignored"})
    {:ok, %{result: "test", extra: "ignored"}}

    iex> ExampleAction.validate_output(%{extra: "ignored"})
    {:error, "Invalid output for Action: Required key :result not found"}

# `validate_params`

```elixir
@spec validate_params(map()) :: {:ok, map()} | {:error, String.t()}
```

Validates the input parameters for the Action.

## Examples

    iex> defmodule ExampleAction do
    ...>   use Jido.Action,
    ...>     name: "example_action",
    ...>     schema: [
    ...>       input: [type: :string, required: true]
    ...>     ]
    ...> end
    ...> ExampleAction.validate_params(%{input: "test"})
    {:ok, %{input: "test"}}

    iex> ExampleAction.validate_params(%{})
    {:error, "Invalid parameters for Action: Required key :input not found"}

# `vsn`

Returns the version of the Action.
