Jido

jido is the upstream Hex package name.

Start Here

Use this skill for the core agent runtime and orchestration layer.

Good triggers:

• "Design a Jido agent for this workflow."
• "Refactor this runtime loop into actions, directives, and signals."
• "Turn the Jido docs into a runnable agent example."
• "Review whether a feature belongs in core Jido or a package-specific extension."

Read references/builder-notes.md before coding when the task spans multiple Jido concepts or packages.

Primary Workflows

Design an agent runtime

• Start with the agent boundary: state, directives, allowed actions, emitted signals, and external dependencies.
• Keep planning and execution explicit. Do not smuggle hidden orchestration into one action or one callback.
• Prefer small, composable workflows that can be tested without a full application shell.

Compose ecosystem packages

• Reach for jido-action when the job is an executable unit of work.
• Reach for jido-signal when the job is event shape and dispatch.
• Reach for jido-memory, req-llm, llm-db, or ash-jido only when the feature truly crosses into those domains.

Turn docs into runnable examples

• Build a thin end-to-end example: agent definition, one or two actions, one signal path, and one observable result.
• Prefer examples that demonstrate runtime decisions or directives over static data transforms.
• Keep examples executable in tests or iex, not locked to a large demo app.

Review boundaries

• Keep core runtime coordination in jido.
• Push provider, catalog, browser, memory, and Ash-specific details into their package skills.
• Narrow proposals that require undocumented runtime hooks.

Build Checklist

• Define the agent state and lifecycle before writing callbacks.
• List the actions, directives, and signals that participate.
• Identify external integrations and keep them behind package boundaries.
• Add tests for state transitions, directive behavior, and failure recovery.

Boundaries

• Do not use this skill for package-specific transport or provider code when another package already owns that boundary.
• Do not invent runtime primitives that the docs do not support.
• Do not let one agent absorb unrelated business workflows that should remain separate.
