charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(cliproxy): add account safety guards to prevent Google account bans Implements cross-provider isolation to prevent Google from flagging concurrent OAuth usage across different client IDs (ref: #509, #512). Three pillars: 1. Auto-pause enforcement at session launch — conflicting accounts in other Google OAuth providers are paused so CLIProxyAPI can't use them, restored on session exit with crash recovery via auto-paused.json 2. Ban/disable detection — error responses matching Google ban patterns auto-pause the affected account to prevent further damage 3. Cross-provider conflict warnings during OAuth registration Key design decisions: - PID-based session tracking for crash recovery (dead PID = restore) - Timestamp comparison prevents restoring ban-paused accounts on exit - Schema validation on auto-paused.json prevents corrupted state - Falls back to warn-only when another session is managing isolation * fix(cliproxy): address code review feedback (attempt 1/5) - Re-read auto-paused.json before write in enforceProviderIsolation to reduce concurrent write race window - Use actual email from registry for display instead of raw accountId - Export maskEmail for testability - Add 27 unit tests covering ban detection, email masking, cross-provider duplicate detection, enforcement lifecycle, crash recovery, and timestamp-guarded restore * fix(cliproxy): address remaining review feedback (attempt 2/5) - Add handleBanDetection test verifying account pause on ban error - Add warnCrossProviderDuplicates tests (true/false/non-Google) - Document PID reuse limitation in isPidAlive JSDoc comment --- src/cliproxy/account-safety.ts | 376 +++++++++++++ src/cliproxy/auth/oauth-handler.ts | 21 +- src/cliproxy/executor/index.ts | 20 + src/cliproxy/executor/retry-handler.ts | 10 + tests/unit/cliproxy/account-safety.test.ts | 621 +++++++++++++++++++++ 5 files changed, 1047 insertions(+), 1 deletion(-) create mode 100644 src/cliproxy/account-safety.ts create mode 100644 tests/unit/cliproxy/account-safety.test.ts diff --git a/src/cliproxy/account-safety.ts b/src/cliproxy/account-safety.ts new file mode 100644 index 00000000..522c248e --- /dev/null +++ b/src/cliproxy/account-safety.ts @@ -0,0 +1,376 @@ +/** + * Account Safety Guards + * + * Prevents Google account bans by: + * 1.

charset=UTF-8 Content-Transfer-Encoding: 8bit * fix(cliproxy): migrate deprecated gemini-claude-* model names to upstream claude-* names (#515) * fix(cliproxy): migrate deprecated gemini-claude-* model names to upstream claude-* names CLIProxyAPI registry no longer recognizes the gemini-claude-* prefix convention. Model names in catalog, base config, and user settings are migrated to upstream claude-* names. Auto-migration in env-builder rewrites existing user settings on load and persists the change. Closes #513 * fix: address code review feedback — sync UI layer and add migration tests - Sync UI isNativeGeminiModel() with backend (remove gemini-claude- exclusion) - Update UI model catalog agy entries from gemini-claude-* to claude-* - Update CI/CD workflow and code-reviewer default model names - Add unit tests for migrateDeprecatedModelNames() logic * fix(hooks): isolate image type check before error-prone processing (#514) * fix(hooks): isolate image type check before error-prone processing Restructure processHook() into two phases so non-image Read calls never see hook error messages. Phase 1 defensively checks tool name and file extension, exiting 0 silently on any failure. Phase 2 only runs for confirmed image/PDF files where errors are relevant. Closes #511 * fix(hooks): sync image analyzer hook file on every profile launch Add installImageAnalyzerHook() call to cliproxy executor, matching the existing installWebSearchHook() pattern. This ensures the .cjs file in ~/.ccs/hooks/ gets refreshed from the npm package on every launch, so users receive hook updates after npm update. * chore(release): 7.41.0-dev.1 [skip ci] * fix(cliproxy): add fork:true for Claude model aliases in config generator (#523) Config generator now outputs fork:true for Claude model alias entries, ensuring both upstream (claude-*) and aliased (gemini-claude-*) model names appear in /v1/models listings. Also preserves fork flag when parsing user-added aliases during config regeneration. Bumps config version to v7 to trigger regeneration on next ccs doctor. Closes #522 * chore(release): 7.41.0-dev.2 [skip ci] * feat(cliproxy): add account safety guards to prevent Google account bans (#516) * feat(cliproxy): add account safety guards to prevent Google account bans Implements cross-provider isolation to prevent Google from flagging concurrent OAuth usage across different client IDs (ref: #509, #512). Three pillars: 1. Auto-pause enforcement at session launch — conflicting accounts in other Google OAuth providers are paused so CLIProxyAPI can't use them, restored on session exit with crash recovery via auto-paused.json 2. Ban/disable detection — error responses matching Google ban patterns auto-pause the affected account to prevent further damage 3. Cross-provider conflict warnings during OAuth registration Key design decisions: - PID-based session tracking for crash recovery (dead PID = restore) - Timestamp comparison prevents restoring ban-paused accounts on exit - Schema validation on auto-paused.json prevents corrupted state - Falls back to warn-only when another session is managing isolation * fix(cliproxy): address code review feedback (attempt 1/5) - Re-read auto-paused.json before write in enforceProviderIsolation to reduce concurrent write race window - Use actual email from registry for display instead of raw accountId - Export maskEmail for testability - Add 27 unit tests covering ban detection, email masking, cross-provider duplicate detection, enforcement lifecycle, crash recovery, and timestamp-guarded restore * fix(cliproxy): address remaining review feedback (attempt 2/5) - Add handleBanDetection test verifying account pause on ban error - Add warnCrossProviderDuplicates tests (true/false/non-Google) - Document PID reuse limitation in isPidAlive JSDoc comment * chore(release): 7.41.0-dev.3 [skip ci] * feat(cliproxy): runtime quota monitoring during active sessions (#529) * feat(cliproxy): add runtime quota monitoring during active sessions Adds adaptive background quota polling to detect and respond to quota exhaustion during active CLIProxy sessions. Prevents rate-limit-driven account bans by auto-cooling exhausted accounts and switching defaults. - Adaptive polling: 300s normal, 60s at 20% threshold, stops at 0% - Stderr warnings at 20%, boxed exhaustion alerts at 0% - Cooldown + default switch on exhaustion (existing patterns) - Configurable via quota_management.runtime_monitor in config.yaml - Timer.unref() prevents blocking process exit - monitorStopped guard for in-flight poll safety Closes #524 * fix: address code review feedback (attempt 1/5) - M1: Round quotaPercent display with Math.round() to avoid ugly floats - M2: Rename exhaust_threshold -> exhaustion_threshold for consistency with existing auto.exhaustion_threshold config field - M3: Replace async not.toThrow() with direct await assertion pattern * fix: address code review feedback (attempt 2/5) - Remove .claude/agent-memory/ from tracking and add to .gitignore - Unify cooldown_minutes default to 5 (was 10 in runtime_monitor, 5 in auto) - Add threshold validation in startQuotaMonitor (warn > exhaustion) - Document intentional post-switch monitoring gap in code comment * chore(release): 7.41.0-dev.4 [skip ci] * fix(cliproxy): mask email in ban detection and fix JSDoc default - Use maskEmail() in handleBanDetection output for consistency - Fix cooldown_minutes JSDoc: default is 5, not 10 * chore(release): 7.41.0-dev.5 [skip ci] * fix(cliproxy): address all review feedback (Low + informational) - Add sync constraint comment on process.exit handler (executor) - Add TOCTOU race acceptability comment (account-safety) - Mask email in handleQuotaExhaustion reason string - Use realistic exhaustion_threshold (5) in test configs * chore(release): 7.41.0-dev.6 [skip ci] --------- Co-authored-by: github-actions[bot] --- .github/workflows/ai-review.yml | 10 +- .gitignore | 1 + config/base-agy.settings.json | 2 +- lib/hooks/image-analyzer-transformer.cjs | 45 +- package.json | 2 +- scripts/code-reviewer.ts | 2 +- src/cliproxy/account-safety.ts | 471 +++++++++++++ src/cliproxy/auth/oauth-handler.ts | 21 +- src/cliproxy/config/env-builder.ts | 52 ++ .../config/extended-context-config.ts | 2 +- src/cliproxy/config/generator.ts | 46 +- src/cliproxy/executor/index.ts | 34 + src/cliproxy/executor/retry-handler.ts | 10 + src/cliproxy/executor/session-bridge.ts | 4 + src/cliproxy/model-catalog.ts | 14 +- src/cliproxy/quota-manager.ts | 135 ++++ src/config/unified-config-loader.ts | 20 + src/config/unified-config-types.ts | 34 + tests/e2e/image-analyzer-hook.e2e.test.ts | 4 +- .../account-safety-quota-exhaustion.test.ts | 312 +++++++++ tests/unit/cliproxy/account-safety.test.ts | 621 ++++++++++++++++++ tests/unit/cliproxy/config-generator.test.js | 104 +++ .../cliproxy/env-builder-migration.test.ts | 247 +++++++ .../cliproxy/extended-context-config.test.ts | 12 +- tests/unit/cliproxy/model-catalog.test.js | 32 +- tests/unit/cliproxy/model-config.test.js | 20 +- .../cliproxy/quota-monitor-runtime.test.ts | 179 +++++ .../unit/cliproxy/thinking-validator.test.ts | 2 +- tests/unit/commands/env-command.test.ts | 4 +- tests/unit/utils/prompt.test.js | 6 +- ui/src/lib/extended-context-utils.ts | 4 +- ui/src/lib/model-catalogs.ts | 42 +- 32 files changed, 2384 insertions(+), 110 deletions(-) create mode 100644 src/cliproxy/account-safety.ts create mode 100644 tests/unit/cliproxy/account-safety-quota-exhaustion.test.ts create mode 100644 tests/unit/cliproxy/account-safety.test.ts create mode 100644 tests/unit/cliproxy/env-builder-migration.test.ts create mode 100644 tests/unit/cliproxy/quota-monitor-runtime.test.ts diff --git a/.github/workflows/ai-review.yml b/.github/workflows/ai-review.yml index a3e86981..5630e449 100644 --- a/.github/workflows/ai-review.yml +++ b/.github/workflows/ai-review.yml @@ -70,12 +70,12 @@ jobs: # CLIProxy environment for model routing env: ANTHROPIC_BASE_URL: http://localhost:8317 -

12 Feb 2026 03:15:24 +0700 Subject: [PATCH 29/33] fix(cursor): address third-round review feedback for protobuf module HIGH PRIORITY FIXES: - Extract shared buffer parsing logic into parseProtobufFrames generator method (DRY violation fix) - both JSON and SSE transformers now use common frame parsing loop, eliminating ~60% code duplication - Use COMPRESS_FLAG constants instead of hardcoded 0x01/0x02/0x03 in parseConnectRPCFrame for better maintainability MEDIUM PRIORITY FIXES: - Return empty buffer on gzip decompression failure (prevents silent data corruption) - ALREADY FIXED - Add debug warning for unknown message roles in convertMessages - Create GitHub issue #535 for FIELD namespace refactoring follow-up - Add test coverage: transformProtobufToSSE, error paths, unknown roles LOW PRIORITY FIXES: - Rename checksum test to clarify timestamp granularity (~16 min) - Fix debug log function name in SSE transformer - FIXED BY REFACTOR - Add comment to TOOL_RESULT_RESULT field documenting future use All tests pass (1593 pass, 0 fail) All validation checks pass (typecheck + lint + format + tests) --- src/cursor/cursor-executor.ts | 186 +++++++++----------
