name: guide-execution description: Resolves the active slice and routes execution-layer work to the right skill.
Guide Execution
Use this skill as the execution-layer entrypoint when you need to decide the next step for one execution slice.
Responsibilities
- Resolve or initialize the active slice.
- Verify required files, registry state, and slice metadata.
- Decide whether work belongs in the planning layer or the slice-scoped execution layer.
- Route slice-scoped work to
brief,blueprint, active repository implementation,review-execution, orclose-slice. - Update slice readiness status when a phase is complete.
guide-execution owns orchestration and readiness only. It should not absorb artifact authoring that belongs to brief, blueprint, review-execution, or close-slice.
When .skills/execution.json sets auto_start_implementation to true, treat blueprint_ready as an automatic handoff into implementation: once blueprint.md is complete, update the slice through manage_execution.py set-status <slice> blueprint_ready, let the tooling advance the slice to execution_ready, and continue directly into code changes instead of stopping for a second manual handoff.
Entry Decision Guide
Use guide-execution when a slice already exists or you need to decide the next step for execution-layer work.
- If the work is still feature-scoped or story-scoped, send it back to
guide-planning. - If there is one execution-ready work item but no slice-scoped execution slice yet, route to
sliceafter confirming the reviewed planning artifacts were approved and committed. - If a slice exists or can be resolved, stay in
guide-executionand route inside the execution layer.
Workflow Boundary
Typical handoff:
guide-planning -> discover -> design -> ui-flow -> breakdown -> review-planning -> human approval -> commit -> slice -> guide-execution
guide-execution owns slice/document readiness only:
draftbrief_readyblueprint_readyexecution_readyclosed
Do not duplicate day-to-day implementation states like implementing or blocked in the slice registry.
Preflight
- Resolve
.skills/execution.jsonand the configured slice registry. - Resolve the active slice using
sirius manage-execution get-activeor a user-provided ID/path. Do not refer to aresolve-activecommand because the execution tool exposesget-active. - Confirm the slice path represents one execution-ready work item.
- Check
brief.md,blueprint.md, optional legacyslices.md, and.slice-meta.jsonas appropriate for the current state. - Check whether
auto_start_implementationis enabled so the blueprint handoff behavior matches repository config. - Repair registry inconsistencies before routing deeper into execution.
Tooling
Always use sirius manage-execution for initialization, active-slice resolution, status updates, validation, registry synchronization, and relation management. Use get-active when you need the current active slice from the CLI.
