Add New Feature (SAM Workflow)

You MUST convert the user's request into durable SAM artifacts registered via MCP artifact and SAM tools:

• feature-context-{slug}.md (discovery)
• codebase/{FOCUS}.md (optional, analysis)
• architect-{slug}.md (architecture/design spec)
• P{id}-{slug}.yaml (executable task plan with Agents, deps, and verification)

<feature_request> $ARGUMENTS </feature_request>

Artifact Discovery (Pre-Phase)

Before starting any phase, check whether the feature request references a tracked issue — either a GitHub Issue (#N) or a beads issue ID (e.g. bd-a3f8). If an issue selector is present, discover existing artifacts registered on that issue.
