Feature: Issue Assignment & Auto-Triage for Squad Members #4

Summary

Squad currently has no mechanism to connect GitHub Issues to squad members. This feature adds label-based issue assignment, auto-triage by the Lead agent, and automated issue pickup by squad members.

Goals

1. Tag GitHub issues with labels that route them to specific squad members (e.g., squad:ripley, squad:backend)
2. Lead auto-triages incoming issues — analyzing, labeling, and delegating to the right member
3. Squad members pick up and complete assigned issues via Copilot coding agent
4. Auto-configure the repo for issue watching when a squad is initialized

Proposed Approach

Layer 1: Label Infrastructure

• A GitHub Actions workflow (sync-squad-labels.yml) that reads .ai-team/team.md and auto-creates squad:{name} labels (one per member, plus a general squad label for untriaged issues)
• Labels are created/synced whenever team.md changes (push trigger) or on workflow_dispatch
• Color-coded labels for visual distinction

Layer 2: Issue Triage Workflow

• A GitHub Actions workflow (squad-triage.yml) triggered by the squad label being applied to an issue
• The workflow invokes the Lead agent to triage: read the issue, analyze it, assign the correct squad:{member} label(s), and comment with a triage summary
• The Lead can reassign by swapping labels

Layer 3: Issue Pickup & Work

• A GitHub Actions workflow (squad-issue-assign.yml) triggered when a squad:{member} label is applied
• Triggers a Copilot coding agent session for that specific member to work the issue
• The coordinator prompt is updated to check for assigned issues at session start
• Members comment on the issue with progress/completion updates

Layer 4: Init-Time Setup

• index.js updated to install the new workflow files during npx github:bradygaster/squad
• The upgrade command also updates these workflows
• New workflow templates added to templates/

Implementation Todos

• Create sync-squad-labels.yml workflow — reads team roster, creates/updates squad:{name} labels via GitHub API
• Create squad-triage.yml workflow — triggered by squad label, invokes Lead agent for triage
• Create squad-issue-assign.yml workflow — triggered by squad:{member} label, triggers Copilot coding agent
• Update squad.agent.md — add issue awareness at session start
• Update index.js — copy workflow files during init/upgrade
• Update templates/routing.md — add issue routing rules
• Add tests for new init/upgrade behavior
• Update README.md with documentation

Notes

• The squad label (no member suffix) is the "inbox" — untriaged issues
• squad:{name} labels are per-member assignments
• The Lead performs triage and delegates to the right member
• Members can reassign by swapping labels
• Requires issues: write and contents: read permissions
• Copilot coding agent must be enabled on the repo (documented as prerequisite)
