Break intent into required behaviors

Break intent down into behaviors and use cases needed to fulfill it

Breaking down a user intent into concrete taproot UseCase behaviors and documenting the decomposition

• · Intent specification from taproot project
• · Focus area argument (optional)

• · Set of required UseCase behaviors documented
• · Decomposition saved to taproot project output directory
• · Updated OVERVIEW.md with current project state

• · taproot skills (@{project-root}/taproot/agent/skills/decompose.md)
• · node dist/cli.js CLI (not bare taproot command)

• · taproot project initialized
• · decompose.md skill file exists at project-root/taproot/agent/skills/
• · node and dist/cli.js available

• · taproot project not initialized
• · decompose.md skill file missing
• · node dist/cli.js command fails or not found

• · Uses node dist/cli.js instead of bare taproot (enforces CLI consistency)
• · Calls node dist/cli.js overview to update OVERVIEW.md automatically
• · Reads full skill definition from decompose.md before executing
• · Follows taproot command naming conventions (tr-decompose mapped to /taproot:decompose)
