# plan
Break down work, scope items, prioritize, and estimate effort.
This capability is exercised during the new -> open phase.
## Constraints
| May modify files | no | Planning scopes work, does not produce code |
| May run tests | no | No code to test at this stage |
| May create items | only with `create` | Breaking down epics requires item creation |
| May change status | yes | Move items through triage |
## Agent Configuration
```yaml
agent:
name: planner
permissions:
allowed: [read, search, grep]
denied: [write, edit, delete, bash]
applicable_tools: [claude-code, github-copilot, mistral-vibe]
```
## Interaction
Default mode: interactive. The planner presents options with rationale
and waits for the user to decide on scope, priority, and breakdown.
