SquidMesh.Runtime.WorkflowAgent (squid_mesh v0.1.0-alpha.7)

Copy Markdown View Source

Jido-native workflow coordination state for one durable workflow run.

The agent rebuilds from run-thread journal entries and checkpoints. It does not execute workflow steps or mutate the existing runtime tables; it provides the restartable coordination state needed by the Jido-native runtime path.

Types

run_id()

@type run_id() :: String.t()

storage_config()

@type storage_config() :: SquidMesh.Runtime.Journal.storage_config()

Functions

actions()

@spec actions() :: [module()]

Returns the list of actions from all attached plugins.

agent_id(run_id)

@spec agent_id(run_id()) :: String.t()

applied_runnable_keys(agent)

@spec applied_runnable_keys(Jido.Agent.t()) :: MapSet.t(String.t())

capabilities()

@spec capabilities() :: [atom()]

Returns the union of all capabilities from all mounted plugin instances.

Capabilities are atoms describing what the agent can do based on its mounted plugins.

Example

MyAgent.capabilities()
# => [:messaging, :channel_management, :chat, :embeddings]

category()

@spec category() :: String.t() | nil

Returns the agent's category.

cmd(agent, action)

Execute actions against the agent. Pure: (agent, action) -> {agent, directives}

This is the core operation. Actions modify state, directives are external effects. Execution is delegated to the configured strategy (default: Direct).

Action Formats

  • MyAction - Action module with no params
  • {MyAction, %{param: 1}} - Action with params
  • {MyAction, %{param: 1}, %{context: data}} - Action with params and context
  • {MyAction, %{param: 1}, %{}, [timeout: 1000]} - Action with opts
  • %Instruction{} - Full instruction struct
  • [...] - List of any of the above (processed in sequence)

Options

The optional third argument opts is a keyword list merged into all instructions:

  • :timeout - Maximum time (in ms) for each action to complete
  • :max_retries - Maximum retry attempts on failure
  • :backoff - Initial backoff time in ms (doubles with each retry)

Examples

{agent, directives} = SquidMesh.Runtime.WorkflowAgent.cmd(agent, MyAction)
{agent, directives} = SquidMesh.Runtime.WorkflowAgent.cmd(agent, {MyAction, %{value: 42}})
{agent, directives} = SquidMesh.Runtime.WorkflowAgent.cmd(agent, [Action1, Action2])

# With per-call options (merged into all instructions)
{agent, directives} = SquidMesh.Runtime.WorkflowAgent.cmd(agent, MyAction, timeout: 5000)

cmd(agent, action, opts)

description()

@spec description() :: String.t() | nil

Returns the agent's description.

name()

@spec name() :: String.t()

Returns the agent's name.

new(opts \\ [])

@spec new(keyword() | map()) :: Jido.Agent.t()

Creates a new agent with optional initial state.

The agent is fully initialized including strategy state. For the default Direct strategy, this is a no-op. For custom strategies, any state initialization is applied (but directives are only processed by AgentServer).

Examples

agent = SquidMesh.Runtime.WorkflowAgent.new()
agent = SquidMesh.Runtime.WorkflowAgent.new(id: "custom-id")
agent = SquidMesh.Runtime.WorkflowAgent.new(state: %{counter: 10})

pending_results(agent, dispatch_agent)

planned_runnable_keys(agent)

@spec planned_runnable_keys(Jido.Agent.t()) :: [String.t()]

plugin_config(plugin_mod)

@spec plugin_config(module() | {module(), atom()}) :: map() | nil

Returns the configuration for a specific plugin.

Accepts either a module or a {module, as_alias} tuple for multi-instance plugins.

plugin_instances()

@spec plugin_instances() :: [Jido.Plugin.Instance.t()]

Returns the list of plugin instances attached to this agent.

plugin_routes()

@spec plugin_routes() :: [{String.t(), module(), integer()}]

Returns the expanded and validated plugin routes.

plugin_schedules()

Returns the expanded plugin and agent schedules.

plugin_specs()

@spec plugin_specs() :: [Jido.Plugin.Spec.t()]

Returns the list of plugin specs attached to this agent.

plugin_state(agent, plugin_mod)

@spec plugin_state(Jido.Agent.t(), module() | {module(), atom()}) :: map() | nil

Returns the state slice for a specific plugin.

Accepts either a module or a {module, as_alias} tuple for multi-instance plugins.

plugins()

@spec plugins() :: [module()]

Returns the list of plugin modules attached to this agent (deduplicated).

For multi-instance plugins, the module appears once regardless of how many instances are mounted.

Example

MyAgent.plugins()
# => [MyApp.SlackPlugin, MyApp.OpenAIPlugin]

put_checkpoint(storage, agent, opts \\ [])

@spec put_checkpoint(storage_config(), Jido.Agent.t(), keyword()) ::
  :ok | {:error, term()}

rebuild(storage, run_id)

@spec rebuild(storage_config(), run_id()) :: {:ok, Jido.Agent.t()} | {:error, term()}

schema()

@spec schema() :: Zoi.schema() | keyword()

Returns the merged schema (base + plugin schemas).

set(agent, attrs)

@spec set(Jido.Agent.t(), map() | keyword()) :: Jido.Agent.agent_result()

Updates the agent's state by merging new attributes.

Uses deep merge semantics - nested maps are merged recursively.

Examples

{:ok, agent} = SquidMesh.Runtime.WorkflowAgent.set(agent, %{status: :running})
{:ok, agent} = SquidMesh.Runtime.WorkflowAgent.set(agent, counter: 5)

signal_types()

@spec signal_types() :: [String.t()]

Returns all expanded route signal types from plugin routes.

These are the fully-prefixed signal types that the agent can handle.

Example

MyAgent.signal_types()
# => ["slack.post", "slack.channels.list", "openai.chat"]

status(agent)

@spec status(Jido.Agent.t()) :: atom()

strategy()

@spec strategy() :: module()

Returns the execution strategy module for this agent.

strategy_opts()

@spec strategy_opts() :: keyword()

Returns the strategy options for this agent.

strategy_snapshot(agent)

@spec strategy_snapshot(Jido.Agent.t()) :: Jido.Agent.Strategy.Snapshot.t()

Returns a stable, public view of the strategy's execution state.

Use this instead of inspecting agent.state.__strategy__ directly. Returns a Jido.Agent.Strategy.Snapshot struct with:

  • status - Coarse execution status
  • done? - Whether strategy reached terminal state
  • result - Main output if any
  • details - Additional strategy-specific metadata

tags()

@spec tags() :: [String.t()]

Returns the agent's tags.

validate(agent, opts \\ [])

@spec validate(
  Jido.Agent.t(),
  keyword()
) :: Jido.Agent.agent_result()

Validates the agent's state against its schema.

Options

  • :strict - When true, only schema-defined fields are kept (default: false)

Examples

{:ok, agent} = SquidMesh.Runtime.WorkflowAgent.validate(agent)
{:ok, agent} = SquidMesh.Runtime.WorkflowAgent.validate(agent, strict: true)

vsn()

@spec vsn() :: String.t() | nil

Returns the agent's version.
