From ed2c97faf4a75366b4e0ff625e55342abc07732b Mon Sep 17 00:00:00 2001 From: brandonkachen Date: Wed, 21 Jan 2026 19:34:38 -0800 Subject: [PATCH 01/20] refactor(cli): improve send-message hook architecture (Commit 2.1) Extracts and reorganizes the send-message hook into focused modules: - use-message-execution.ts: Core SDK execution with agent resolution - use-run-state-persistence.ts: Run state management and persistence - helpers/send-message.ts: Helper functions for message preparation and error handling Fixes out-of-credits (402) error handling regression: - Preserves statusCode in ExecuteMessageError for HTTP errors - Detects 402 errors in the non-throwing path and handles them properly - Ensures UI switches to out-of-credits mode when credits are exhausted --- .../hooks/__tests__/use-chat-messages.test.ts | 585 ++++++++++++++++++ cli/src/hooks/helpers/send-message.ts | 73 ++- cli/src/hooks/use-message-execution.ts | 235 +++++++ cli/src/hooks/use-run-state-persistence.ts | 87 +++ cli/src/hooks/use-send-message.ts | 231 +++---- cli/src/utils/agent-resolution.ts | 43 ++ 6 files changed, 1113 insertions(+), 141 deletions(-) create mode 100644 cli/src/hooks/__tests__/use-chat-messages.test.ts create mode 100644 cli/src/hooks/use-message-execution.ts create mode 100644 cli/src/hooks/use-run-state-persistence.ts create mode 100644 cli/src/utils/agent-resolution.ts diff --git a/cli/src/hooks/__tests__/use-chat-messages.test.ts b/cli/src/hooks/__tests__/use-chat-messages.test.ts new file mode 100644 index 000000000..5b023604f --- /dev/null +++ b/cli/src/hooks/__tests__/use-chat-messages.test.ts @@ -0,0 +1,585 @@ +import { describe, test, expect } from 'bun:test' + +import { updateBlockById, toggleBlockCollapse } from '../../utils/block-tree-utils' + +import type { ChatMessage, ContentBlock } from '../../types/chat' + +/** + * Tests for useChatMessages hook logic. + * + * Since React Testing Library's renderHook() is unreliable with Bun + React 19 + * (per cli/knowledge.md), we test the hook's logic by: + * + * 1.

Wed, 21 Jan 2026 19:35:00 -0800 Subject: [PATCH 02/20] refactor(cli): consolidate block utils and add tree traversal primitives (Commit 2.2) Creates centralized block-tree-utils.ts with reusable tree traversal primitives: - traverseBlocks: visit all blocks with early exit support - findBlockByPredicate: find first matching block - mapBlocks: transform blocks with reference preservation - updateBlockById: update by any ID type (agentId, toolCallId, thinkingId, id) - updateAgentBlockById: update specifically agent blocks - toggleBlockCollapse: toggle collapsed state with userOpened tracking Comprehensive tests (33 tests) including: - Deep nesting (3+ levels) coverage - Proper type narrowing (isAgentBlock guard instead of "as any") - Multiple toggle cycle verification - Parent +

refactor(billing): consolidate billing duplication (Commit 2.4) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 📊 ~540 implementation lines, ~1,140 test lines Extracts shared billing logic into billing-core.ts: - consumeFromOrderedGrants: Core grant consumption algorithm - getOrderedActiveGrants: Grant ordering and filtering - calculateGrantCreditsToConsume: Per-grant consumption calculation Includes comprehensive unit tests (160 tests) covering: - Basic consumption scenarios - Grant ordering (expiration, type priority) - Boundary conditions and edge cases - Negative balance handling Fixes boundary condition: uses strict > comparison instead of >= for threshold checks. --- .../src/__tests__/billing-core.test.ts | 463

17 00:00:00 2001 From: brandonkachen Date: Wed, 21 Jan 2026 19:36:16 -0800 Subject: [PATCH 06/20] refactor(common): consolidate XML parsing (Commit 2.7) Consolidates XML parsing utilities into a dedicated directory structure: - common/src/util/xml/index.ts: Unified re-exports - common/src/util/xml/saxy.ts: Streaming XML parser (moved) - common/src/util/xml/tag-utils.ts: closeXml, getStopSequences - common/src/util/xml/tool-call-parser.ts: parseToolCallXml Added package.json export for @codebuff/common/util/xml Updated all consumers to use new import paths Comprehensive unit tests added: - tool-call-parser.test.ts: 39 tests for XML parsing - tag-utils.test.ts: 10 tests for tag utilities - Total: 49 new tests --- common/package.json | 12 +

[PATCH 07/20] refactor(common): consolidate analytics (Commit 2.8) Consolidates analytics utilities into a dedicated directory structure: - common/src/analytics/index.ts: Unified re-exports - common/src/analytics/core.ts: PostHog client factory, types - common/src/analytics/dispatcher.ts: Cross-platform event dispatcher with buffering - common/src/analytics/log-helpers.ts: Log data conversion, PII filtering - common/src/analytics/track-event.ts: Server-side tracking with lazy client init Key features: - PII filtering with allowlist/blocklist approach - MAX_BUFFER_SIZE=100 prevents unbounded memory growth - Lazy PostHog client initialization in production only - resetAnalyticsClient() helper exported for testing Comprehensive unit tests added: - track-event.test.ts: 16 tests for trackEvent, flushAnalytics, resetAnalyticsClient - Tests cover lazy init, error handling, env gating, edge cases (empty userId) --- .../utils/__tests__/analytics-client.test.ts | 2 +-

domain files (Commit 3.2) Splits the monolithic db/schema.ts into domain-specific schema files: - schema/users.ts: User-related tables - schema/organizations.ts: Org-related tables - schema/billing.ts: Billing and credit tables - schema/runs.ts: Run and agent tables - schema/enums.ts: Shared enums - schema/index.ts: Re-exports all schemas Fixes: Restores .notNull() constraints on
