multi-model-routinglisted

Use this skill any time a request repeats one operation across many items: summarizing all the logs or documents in a folder, reformatting every file in a directory, tagging or classifying hundreds of rows, reviews, or records, sweeping a codebase for TODOs, or generating dozens-to-hundreds of test records. Phrases like "every file", "all of them", a folder path, or a count ("30 logs", "200 reviews") are the signal -- this is the required way to execute batch work, not an optional optimization, so invoke it before reading any files or writing any code. Also use it whenever another model or agent system enters the picture: a local model engine, OpenCode Zen, Antigravity, Codex/GPT, Gemini, or any non-Claude model -- reaching a model your own harness does not offer, offloading work to save Claude quota, or asking what model backends this machine has. Do not use for single-item analysis, architecture or design, security review, or prose writing.

# Multi-Model Routing You have up to five routing tiers, on four separate meters. Use them deliberately so the owner's Claude usage goes to work that actually needs Claude: 1. **Local model engine** — free, private, no quota. Choose the engine with the largest usable local model inventory; see the selection rule below. 2. **OpenCode Zen** (cloud) — **free, no API key, no account.** 61 models advertised, 8+ of them free-tier. Costs nothing on any meter, which is why it sits above Codex. 3. **Codex CLI** — OpenAI models, billed to the owner's ChatGPT account. Also runs its agent loop on *local* models for free (`--oss`). 4. **Antigravity** (`agy`) — reaches multiple Gemini tiers, Claude on a separate meter, and free GPT-OSS 120B. `agy models` is live and authoritative; don't trust a remembered list, including this one — see `references/cross-agent.md` for current tiers and which job wants which. 5. **Claude subagents** (Agent tool) — billed to the owner's Claude usage. **No single system reaches every model.** Antigravity is the only route to Gemini and GPT-OSS, and a second, separately-billed path to Claude models. Codex is the only route to the GPT-5.x fleet. Routing *across* systems is how you reach a model your own harness doesn't offer — read `references/cross-agent.md` before assuming a model is unavailable. ## Before anything else: read the local notes Read `references/local-notes.md` in this skill folder. It holds machine/account-specific facts
