# Specflow: Deep Onboarding ## When to use **This skill is callable-only** — it carries no trigger surface in the skill listing and is not routed into automatically. Run it when the developer invokes `/specflow-deep-onboard`. Three parallel onboarding passes over a whole codebase is an expensive, deliberate choice, not something a resembling sentence should trip. What follows is its scope, not its triggers. Deep onboarding for codebases where confidence matters. Orchestrates 3 parallel specflow-onboard-codebase passes by spawning separate subagents via the Agent tool, then reads their outputs from disk, compares structurally, investigates disagreements with focused agents, and produces a final merged spec tree. This skill runs in the main Claude Code session (which has access to the Agent tool) — it must NOT be invoked as a subagent itself. For a quick single-pass onboarding, use specflow-onboard-codebase directly instead. Trigger on: "deep onboard", "high-confidence onboarding", "run 3 passes", "multi-pass onboarding", "I need confident specs for this codebase". ## What this skill does Orchestrate 3 parallel specflow-onboard-codebase passes, compare their outputs, investigate disagreements, and produce a final merged spec tree with high confidence. ## Why This Is a Skill, Not an Agent This orchestration requires spawning subagents via the Agent tool. The Agent tool is available to the main Claude Code session but may not be available inside a subagent. By running as a
