Technical project management for Backlog.md workstreams using coordinated sub-agents. Use only when the user explicitly asks Codex to take over one or more existing Backlog.md tasks (for example: "act as TPM", "coordinate these tasks", "delegate to sub-agents"). Orchestrate planning, implementation, and finalization; manage dependencies and overlapping code areas; review and approve sub-agent plans before implementation.
MUST run before any code implementation task. Classifies complexity, discovers local conventions, finds reusable patterns, and prevents blind coding. Invoke this skill before writing or modifying code.
