Orchestrates SDD project initialization — version detection, environment verification, scaffolding, and git setup.
Manage project settings in sdd/sdd-settings.yaml including component settings that drive scaffolding.
Single gateway for all core↔tech-pack interactions. Reads manifests, resolves paths, loads skills/agents, routes commands.
Manage tasks and plans using the .tasks/ directory.
Standards for authoring SDD plugin agents — frontmatter, self-containment, skill references, and no-user-interaction rules.
Standards for authoring SDD plugin commands — frontmatter, user interaction, skill/agent invocation, CLI integration, and output formatting.

| description | Analyze specifications and decompose into independent changes. |
| user-invocable | false |
Analyze a specification document to identify natural change boundaries and return a structured decomposition result. This is a pure analysis skill that takes input and returns output without user interaction.
Schema: schemas/input.schema.json
Accepts decomposition mode, spec content, and mode-specific parameters for outline, section, or hierarchical decomposition.
Schema: schemas/output.schema.json
Returns mode-specific results: outline sections, or hierarchical epic/feature groupings with dependency graph.
For detailed guidance, read these on-demand:
Modes: outline (extract headers), section (analyze one section), hierarchical (epics + features), default (full analysis)
Algorithm phases: Structure Extraction -> Boundary Detection -> Dependency Detection -> Independence Scoring -> Refinement
Complexity levels: SMALL (<= 3 ACs), MEDIUM (4-8 ACs), LARGE (> 8 ACs), EPIC (> 10 ACs + 3+ components)
Independence score: 0.0-1.0 scale; >= 0.5 is standalone, < 0.3 should be merged
