TAD Generator

Generate a Technical Architecture Document (tad.md) with a modular, startup-appropriate design from a PRD.

Terms used throughout:

• PROJECT_DIR: the project folder given in $ARGUMENTS. It holds prd.md, and tad.md is written there.
• Run mode: create when PROJECT_DIR/tad.md does not exist; modify when it exists.
• Ideas repo: the git repository that contains PROJECT_DIR, when its root has scripts/update_readme_ideas_index.py or a README.md ideas table with a TAD column.
• Status: COMPLETE, PARTIAL or BLOCKED, chosen by the rules in Final Report.

Run order: Phase 1 (Repo Sync runs inside it), Phases 2-7, then Phase 8 (the Final Report). A modify run replaces Phases 2-5 step 1 with Modification Mode. A stop at any point still produces the Final Report.

Subagent Architecture

This skill uses parallel research agents with upfront content extraction. Pattern: D (Research+Synthesis) + E (Staged Pipeline).
