| description | Document an SPF use-case record. Use when the user explicitly requests delivery scenarios, variants, relationships, status, or verification. |
Document an SPF use case
Read references/workflow.md completely before acting; it contains the detailed composition, evidence, cascade, and validation workflow.
Confirm that the user explicitly requested creation or revision of the entry. Do not create adjacent feature, use-case, design, or decision records discovered during the workflow; surface them as candidates instead.
Read internal/design/spf/use-cases/README.md, its decomposition rubric, related feature entries, a strong neighboring use case, and current implementation/tests.
- Describe the delivery scenario and the feature additions, removals, swaps, or tuning that compose it.
- Separate current behavior from proposed direction and decisions still needed; label missing constituent features explicitly.
- For shipped variants, retain composition decisions and current source pointers. For future variants, retain the scenario, boundaries, and evidence required before implementation.
- Update directly affected entries only when their facts changed; verify links and relationship symmetry.
Do not duplicate feature definitions, code mechanics, phase tables, or progress logs. When the missing unit is an engine capability, identify it as a candidate for the feature registry; create that entry only if the user explicitly requests it.
Example
Input: “Document low-latency live playback as a composed use case.”
Output: A compact delivery-focused entry naming composition, current status, missing prerequisites, constraints, and source evidence.
