From 601d518737283cbd4a7a311886c8a9b4a5a27d6d Mon Sep 17 00:00:00 2001 From: jasonli0226 Date: Mon, 4 May 2026 01:22:57 +0800 Subject: [PATCH] - Anthropic prompt caching: API integration plus frozen-snapshot system prompt for stable cache hits across turns - Streaming multi-message delivery with per-agent opt-in flag and full design spec / implementation plan - New "# Operating Principles" section in renderSystemPrompt covering tool-use discipline (always) and skill-loading discipline (primary agents only); declarative-vs-imperative writing rule folded into the existing workspace "## Memory" guidance - Prompt-injection scanner sanitises SOUL.md, USER.md, MEMORY.md, and skill descriptions before they reach the system prompt; poisoned content is replaced with a [BLOCKED: ...] marker that preserves section framing - Skill catalog gated on !isSubAgent so spawned sub-agents no longer pay the full 50-skill token cost on every spawn - Folder upload added; upload-zone refactored with 14 new tests - User-creation flow uses crypto.randomUUID - Fixed duplicated edit on user info - Lint/format cleanup pass --- infra/templates/USER.md.template | 3 + .../migration.sql | 3 + .../migration.sql | 2 + .../migration.sql | 5 + packages/api/prisma/schema.prisma | 178 ++++++----- packages/api/src/admin/admin.service.ts | 2 + .../__tests__/agent-error-message.test.ts | 23 ++ .../__tests__/message-router.service.test.ts | 193 ++++++++++++ .../api/src/channels/agent-error-message.ts | 18 ++ .../src/channels/message-router.service.ts | 77 ++++- packages/api/src/chat/chat.controller.ts | 2 +- .../db/__tests__/session.repository.test.ts | 24 ++ .../__tests__/token-usage.repository.test.ts | 101 ++++++ .../api/src/db/agent-definition.repository.ts | 7 + packages/api/src/db/channel.repository.ts | 4 + packages/api/src/db/session.repository.ts | 14 + packages/api/src/db/token-usage.repository.ts | 18 ++ .../__tests__/agent-runner.service.test.ts | 45 +++ .../__tests__/bootstrap-file.service.test.ts | 41 +++ .../__tests__/context-builder-skills.test.ts | 48 +++ .../__tests__/context-builder.service.test.ts | 185 +++++++++++ .../prompt-injection-scanner.test.ts | 147 +++++++++ .../engine/__tests__/reasoning-loop.test.ts | 133 ++++++++ .../__tests__/skill-loader.service.test.ts | 15 + .../__tests__/token-counter.service.test.ts | 91 +++++- .../api/src/engine/agent-runner.service.ts | 13 +- packages/api/src/engine/agent-runner.types.ts | 16 + .../api/src/engine/bootstrap-file.service.ts | 5 +- .../api/src/engine/context-builder.service.ts | 120 ++++++-- .../api/src/engine/context-builder.types.ts | 25 ++ .../src/engine/prompt-injection-scanner.ts | 76 +++++ .../__tests__/anthropic-provider.test.ts | 149 ++++++++- .../__tests__/provider-factory.test.ts | 15 + .../engine/providers/anthropic-provider.ts | 58 +++- .../src/engine/providers/provider-factory.ts | 6 +- packages/api/src/engine/reasoning-loop.ts | 25 ++ .../api/src/engine/reasoning-loop.types.ts | 32 ++ .../api/src/engine/skill-loader.service.ts | 7 +- .../api/src/engine/token-counter.service.ts | 48 ++- .../api/src/workspace/workspace.controller.ts | 4 + .../api/src/workspace/workspace.service.ts | 20 +- .../__tests__/tool-progress-bubble.test.ts | 85 ++++++ .../channels/__tests__/tool-progress.test.ts | 46 +++ .../src/channels/tool-progress-bubble.ts | 85 ++++++ packages/shared/src/channels/tool-progress.ts | 51 ++++ packages/shared/src/index.ts | 10 + .../__tests__/provider-registry.test.ts | 42 +++ .../src/providers/__tests__/types.test.ts | 22 ++ packages/shared/src/providers/index.ts | 2 +- .../shared/src/providers/provider-registry.ts | 24 +- packages/shared/src/providers/types.ts | 12 + packages/shared/src/schemas/agent.schema.ts | 5 + packages/shared/src/schemas/channel.schema.ts | 5 + .../app/(dashboard)/agents/agents-dialogs.tsx | 45 ++- .../app/(dashboard)/agents/agents-list.tsx | 3 + .../(dashboard)/agents/user-agents/page.tsx | 48 ++- .../(dashboard)/conversations/chat-thread.tsx | 35 ++- .../app/(dashboard)/conversations/page.tsx | 16 +- .../app/(dashboard)/conversations/use-chat.ts | 32 +- .../(dashboard)/settings/channels-dialogs.tsx | 58 ++++ .../app/(dashboard)/settings/channels-tab.tsx | 6 +- .../workspace/__tests__/upload-zone.test.tsx | 287 ++++++++++++++++++ .../app/(dashboard)/workspace/upload-zone.tsx | 158 +++++++++- 63 files changed, 2888 insertions(+), 187 deletions(-) create mode 100644 packages/api/prisma/migrations/20260502083535_add_cache_tokens_to_token_usage/migration.sql create mode 100644 packages/api/prisma/migrations/20260502172902_add_cached_system_prompt/migration.sql create mode 100644 packages/api/prisma/migrations/20260503105306_add_streaming_fields/migration.sql create mode 100644 packages/api/src/engine/__tests__/prompt-injection-scanner.test.ts create mode 100644 packages/api/src/engine/prompt-injection-scanner.ts create mode 100644 packages/shared/src/channels/__tests__/tool-progress-bubble.test.ts create mode 100644 packages/shared/src/channels/__tests__/tool-progress.test.ts create mode 100644 packages/shared/src/channels/tool-progress-bubble.ts create mode 100644 packages/shared/src/channels/tool-progress.ts create mode 100644 packages/web/src/app/(dashboard)/workspace/__tests__/upload-zone.test.tsx diff --git a/infra/templates/USER.md.template b/infra/templates/USER.md.template index 960148b..1e6eb05 100644 --- a/infra/templates/USER.md.template +++ b/infra/templates/USER.md.template @@ -17,3 +17,6 @@ ## Special Instructions (User-specific notes and preferences learned over time) + + +> This is your structured profile of the user.
