Spec Guardian: Lead Reviews, Teammates Implement

Overview

This skill implements the spec guardian pattern for the teams-spec trait. The lead session does not implement any tasks. Instead, it:

1. Reads tasks from tasks.md
2. Spawns teammates in isolated git worktrees
3. Reviews each teammate's completed work against spec.md
4. Merges compliant changes, rejects non-compliant work with feedback
5. Updates tasks.md with final state

This skill supersedes spex:teams-orchestrate when both teams-vanilla and teams-spec traits are active. Check .specify/spex-traits.json for teams-spec: true to confirm this skill should run.

1. Task Graph Analysis

Same as spex:teams-orchestrate: read tasks.md, identify independent task groups, determine parallel opportunities.
