## Thinking Path The same 2026-04-30 audit that produced PR #4118 (`Invalid session` regex extension) and the ENOTFOUND classifier (#4931) identified a third stuck-session pattern: **13 failures in 7 days, all on a single agent (Ernest)**, with stderr matching: ``` _ApiError: {"error":{"code":400,"message":"The input token count exceeds the maximum number of tokens allowed 1048576","status":"INVALID_ARGUMENT"}} at ChatCompressionService.compress ``` The root cause is that gemini-cli's `ChatCompressionService` blew the 1M token context limit **during its compression step itself**. Resuming the same session ID will hit the same wall on the next attempt — the session is effectively dead the same way it is when "Invalid session identifier" fires (PR #4118). ## What Changed Extends the `isGeminiUnknownSessionError` regex in `parse.ts` with two phrases: - `exceeds\s+the\s+maximum\s+number\s+of\s+tokens` - `input\s+token\s+count\s+exceeds` Both trigger the **existing** fresh-session retry path in `execute.ts:596` — no new code path. Same extension pattern as PR #4118. ## Verification - `npx vitest run --project @paperclipai/adapter-gemini-local` → 14/14 pass (11 in `parse.test.ts` + 3 existing in `execute.remote.test.ts`) - 2 new tests cover the token-overflow patterns - `pnpm --filter @paperclipai/adapter-gemini-local typecheck` → clean - Audit query against `heartbeat_runs.stderr_excerpt` confirms regex matches all 13 occurrences ## Stacking This PR is stacked on top of #4931 (the ENOTFOUND classifier) which adds the `parse.test.ts` file. If #4931 merges first, this PR's diff is just the regex + 2 tests. If this PR is reviewed first, please merge #4931 first to avoid touching the same test scaffolding twice. ## Risks - **Low.** Single-line regex extension. No new code paths. - The session-reset path is well-trodden (PR #4118 in flight). - If a non-Gemini caller produces a stderr containing "exceeds the maximum number of tokens" by coincidence, they would trigger one unnecessary fresh-session retry. Not plausible in the gemini-cli output context where this stderr is sourced. ## Model Used Claude Opus 4.7 (1M context), Anthropic SDK via Claude Code CLI. ## Checklist - [x] Thinking path traces from audit data to single-line regex change - [x] Model specified - [x] No duplicate of planned core work - [x] Tests pass locally - [x] Tests added (2 new) - [x] N/A — server-side regex - [x] Internal pattern; no docs change - [x] Risks documented - [x] Will address Greptile + reviewer comments before merge - [x] I searched the GitHub PR list for similar PRs and confirmed this is not a duplicate (related: #4118 covers the "Invalid session identifier" regex; this PR extends the same regex with token-overflow phrases) 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Devin Foley <devin@paperclip.ing> Co-authored-by: Paperclip <noreply@paperclip.ing>
