From 36b34de65e51373e54a066014df3a99154de5b19 Mon Sep 17 00:00:00 2001 From: Ryder Freeman Date: Tue, 31 Mar 2026 13:50:08 -0700 Subject: [PATCH] fix(executor): auto-fallback to API key when gemini-cli OAuth capacity exhausted When gemini-cli ACP transport fails with "No capacity available" or similar rate-limit errors, CSA now automatically: 1. Detects the capacity/quota error pattern in the result 2. Reads api_key from [tools.gemini-cli] config 3. Injects GEMINI_API_KEY env var and retries ONCE 4. Logs warning when fallback is used The first attempt always uses OAuth (no API key injected). Only on capacity exhaustion is the stored API key used as fallback.
