Use for any non-trivial pi-actors operation, diagnosis, or development involving Recipes, persistent tools, Runs, spawn, message, inspect, Trace, Control, capability specialization, or activation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Actors
## Choose the operation
Start from the intended outcome:
```text
Run a maintained capability once
→ use spawn recipe=<skill>/<recipe>
Make a maintained capability a persistent agent-callable tool
→ use register_tool from=<skill>/<recipe>
Keep the same capability but narrow caller defaults
→ use register_tool from=<skill>/<recipe> defaults={...}
Register a trusted command directly
→ use register_tool template="..."
Build a reusable multi-node execution graph
→ author a Recipe with named imports
Run a long-lived controlled process
→ spawn its async Recipe, then use message and inspect
Coordinate several independent actors or subagents
→ also read the swarm Skill
Choose capability-specific behavior
→ read the owning capability Skill
Diagnose resolution, registration, or activation
→ use Inspect status/doctor flows and stop on contradictory evidence
```
Use [persistent tools](./references/persistent-tools.md), [Recipes](./references/recipes.md), [Runs](./references/runs.md), or [diagnostics](./references/diagnostics.md) only when the selected operation needs that detail.
## Core distinctions
Keep these boundaries explicit:
```text
Skill Recipe ≠ registered tool

How to install
mdr add llblab/pi-actors/actors@sha256:8439a0a87efeada6The line at the top of this page pins the label git:20261108.4461d0f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
