Maestro

Achieve Frontier AI performance in your CLI — by fusing the model CLIs you already run. Fan one prompt across a panel of 1-8 of your local CLIs in parallel, have a judge model you pick read every answer into a structured analysis, then a synthesizer you pick write one grounded answer that does not majority-vote. On a 100-task benchmark, every fusion panel outscored its individual member models. It runs on Maestro's discipline layer: verified done-claims, surgical scope, and a research-backed multi-agent gate.

_{17 fixture tasks · 147 valid A/B runs · 11 voids excluded & re-run · 6 hooks, all tested · ~10 KB always-on kernel · plugin + portable installs}

UPDATED — catalog-first Frontier. Run maestro frontier catalog to see the locally selectable models, named presets (including legacy presets), aliases, and readiness requirements. Compose a panel from ready models with maestro frontier compose --models ...; the catalog never prints configured model IDs or secret values. Full walkthrough in The Frontier Engine.

One suite: fuse the answer, make the case, guard the spend.

• Maestro Frontier — Fuses the model CLIs you already run into one judged, grounded answer.
• Maestro Agora — Turns verified product truth into concise, argument-first copy without inventing the proof.
• Maestro CostGuard — Audits CI and cloud infrastructure for cost leaks and shows what to fix.

Install — run the command block for your tool, inside that tool. Claude Code and Codex use native plugins. Cursor, Gemini, Cline, Windsurf, and other CLIs use the portable installer, which copies Maestro's runtime-agnostic files into the current project/workspace by default. Global/user installs are optional when you intentionally want cross-project behavior.

Claude Code (terminal) — native plugin (enforcement hooks, /maestro:* commands, skills, status line, Frontier auto-run). Run these inside the claude CLI:

/plugin marketplace add mbanderas/maestro
/plugin install maestro@maestro

Claude desktop app — the desktop app has no /plugin slash command, and its + → Plugins browser only lists Anthropic's official marketplace, so it cannot add this repo from the GUI. Install Maestro by running the two commands above in a terminal (claude on the same machine), or register the marketplace in .claude/settings.json under extraKnownMarketplaces. See the official Claude Code plugins docs.

Codex CLI (terminal) — native Codex plugin via the Maestro repo marketplace (skills, trusted hooks, and Frontier auto-run after you review and trust the hooks):

codex plugin marketplace add mbanderas/maestro
codex plugin add maestro@maestro

Codex desktop / IDE app — the in-app Plugins directory installs plugins from marketplaces Codex already knows; adding a new repo marketplace is a CLI action, so run the two commands above in a terminal (codex). See the official Codex plugins docs.
