Summary

Adds GitHub Copilot as a fourth agent in the agents panel, alongside Claude, Codex, and Fireworks. Ships the omarchy-agent-usage-copilot collector, panel icons, and test coverage — the plugin itself is untouched, since a new collector is all a new agent needs.

How it works

Local stats. The Copilot CLI's session store (~/.copilot/session-store.db) records every billed request in its assistant_usage_events table: day, model, session, token split, and cost in nano AI units. The collector snapshots the WAL-mode database via SQLite's online backup API (no copying of db + -wal siblings, no blocking the writer) and aggregates in Python. CLI versions whose store predates that table fall back to scanning session transcripts under ~/.copilot/session-state. Neither source needs the network. Honors COPILOT_HOME for non-default installs, like CLAUDE_CONFIG_DIR / CODEX_HOME in the other collectors.

Monthly allowance. The meter is an allowance of AI credits. When GitHub's internal quota endpoint (the one the editor plugins use) answers, the account-wide figure is authoritative — it counts every machine, IDE, and agent on the entitlement, and provides the plan label and reset date. The probe needs a token from COPILOT_QUOTA_TOKEN, GH_TOKEN, GITHUB_TOKEN, or gh auth token; every failure is soft and falls back to this machine's CLI spend against a plan allowance from ~/.config/omarchy/agents/copilot.json:

{ "plan": "pro", "monthlyCredits": 1500, "remote": true }

 plan  ( free / student / pro / pro+ / max / business / enterprise ) picks a default allowance;  monthlyCredits  overrides it;  remote  turns the quota probe off. A meter labeled "(est.)" is the local estimate; a plain "Monthly allowance" is the live account figure. A machine that never ran the CLI reports nothing and the panel stays hidden, per the plugin's contract.

Follows the sibling collectors' conventions: same  --force  /  --limits-only  freshness contract, versioned cache envelope, atomic cache writes, and auth guidance surfaced in  authHelpText .

Confidence Score: 5/5

[Medium risk] Adds a new agent collector for GitHub Copilot usage.

The PR appears safe to merge based on the changes since the previous review.

Summary

The PR adds a Copilot usage collector, panel icons, documentation, and tests. The collector reads a SQLite session store or transcript fallback and uses a remote account quota when available.

Thank you! Brought in with your authorship in #14040, reindented to two spaces, with the plan and allowance taken from GitHub's live answer and the last allowance kept through a failed check until it resets.
