From e6e54822f58116a18958a3fe98f44064e44180bc Mon Sep 17 00:00:00 2001 From: oyi77 Date: Wed, 1 Apr 2026 03:39:07 +0700 Subject: [PATCH] feat: add Memory & Skill Injection from Proxy (Network Level) Implements transparent memory and skill injection at the proxy layer, enabling AI agents connecting through OmniRoute to automatically inherit memory and tool capabilities without client-side code changes. Memory System: - SQLite-backed memory store with 4 types: factual, episodic, procedural, semantic - Token budget retrieval with configurable max tokens (default 2000) - Memory injection into chat requests (system message + message prefix) - Memory fact extraction from responses - Dashboard page: /dashboard/memory - MCP tools: omniroute_memory_search, omniroute_memory_add, omniroute_memory_clear Skills System: - Skill registry with semver resolution (^, ~, >=, etc.) - Docker sandbox runner with resource constraints (CPU 100ms, RAM 256MB) - Skill executor with timeout handling - Built-in skills: file_read, file_write, http_request, web_search, eval_code, execute_command - Skill schema injection for OpenAI, Claude, Gemini formats - Tool call interception and execution - Dashboard page: /dashboard/skills - MCP tools: omniroute_skills_list, omniroute_skills_enable, omniroute_skills_execute Advanced Features: - Browser automation skill (Playwright-based) - A2A memory-aware routing skill - Hybrid execution mode (direct/sandbox/auto-upgrade) - Custom skill registration API - Integration tests - Memory caching layer - Memory summarization - Performance benchmarks Resolves: GitHub Issue #812 --- open-sse/handlers/chatCore.ts | 22 ++ open-sse/mcp-server/tools/memoryTools.ts | 118 ++++++ open-sse/mcp-server/tools/skillTools.ts | 120 +++++++ src/app/(dashboard)/dashboard/memory/page.tsx | 197 ++++++++++ .../settings/components/MemorySkillsTab.tsx | 251 +++++++++++++ .../(dashboard)/dashboard/settings/page.tsx | 15 +- src/app/(dashboard)/dashboard/skills/page.tsx | 230 ++++++++++++ src/lib/benchmarks.ts | 33 ++ src/lib/db/migrations/014_create_memories.sql | 22 ++ .../migrations/014_create_memories_down.sql | 4 + src/lib/db/migrations/015_create_skills.sql | 37 ++ .../db/migrations/015_create_skills_down.sql | 5 + src/lib/memory/__tests__/injection.test.ts | 206 +++++++++++ src/lib/memory/__tests__/schemas.test.ts | 44 +++ src/lib/memory/cache.ts | 64 ++++ src/lib/memory/extraction.ts | 180 ++++++++++ src/lib/memory/injection.ts | 104 ++++++ src/lib/memory/retrieval.ts | 99 +++++ src/lib/memory/schemas.ts | 46 +++ src/lib/memory/store.ts | 339 ++++++++++++++++++ src/lib/memory/summarization.ts | 99 +++++ src/lib/memory/types.ts | 41 +++ src/lib/skills/__tests__/integration.test.ts | 47 +++ src/lib/skills/a2a.ts | 34 ++ src/lib/skills/builtin/browser.ts | 35 ++ src/lib/skills/builtins.ts | 68 ++++ src/lib/skills/custom.ts | 41 +++ src/lib/skills/executor.ts | 167 +++++++++ src/lib/skills/hybrid.ts | 67 ++++ src/lib/skills/injection.ts | 119 ++++++ src/lib/skills/interception.ts | 135 +++++++ src/lib/skills/registry.ts | 211 +++++++++++ src/lib/skills/sandbox.ts | 160 +++++++++ src/lib/skills/schemas.ts | 47 +++ src/lib/skills/types.ts | 57 +++ tests/unit/memory-extraction.test.mjs | 169 +++++++++ 36 files changed, 3627 insertions(+), 6 deletions(-) create mode 100644 open-sse/mcp-server/tools/memoryTools.ts create mode 100644 open-sse/mcp-server/tools/skillTools.ts create mode 100644 src/app/(dashboard)/dashboard/memory/page.tsx create mode 100644 src/app/(dashboard)/dashboard/settings/components/MemorySkillsTab.tsx create mode 100644 src/app/(dashboard)/dashboard/skills/page.tsx create mode 100644 src/lib/benchmarks.ts create mode 100644 src/lib/db/migrations/014_create_memories.sql create mode 100644 src/lib/db/migrations/014_create_memories_down.sql create mode 100644 src/lib/db/migrations/015_create_skills.sql create mode 100644 src/lib/db/migrations/015_create_skills_down.sql create mode 100644 src/lib/memory/__tests__/injection.test.ts create mode 100644 src/lib/memory/__tests__/schemas.test.ts create mode 100644 src/lib/memory/cache.ts create mode 100644 src/lib/memory/extraction.ts create mode 100644 src/lib/memory/injection.ts create mode 100644 src/lib/memory/retrieval.ts create mode 100644 src/lib/memory/schemas.ts create mode 100644 src/lib/memory/store.ts create mode 100644 src/lib/memory/summarization.ts create mode 100644 src/lib/memory/types.ts create mode 100644 src/lib/skills/__tests__/integration.test.ts create mode 100644 src/lib/skills/a2a.ts create mode 100644 src/lib/skills/builtin/browser.ts create mode 100644 src/lib/skills/builtins.ts create mode 100644 src/lib/skills/custom.ts create mode 100644 src/lib/skills/executor.ts create mode 100644 src/lib/skills/hybrid.ts create mode 100644 src/lib/skills/injection.ts create mode 100644 src/lib/skills/interception.ts create mode 100644 src/lib/skills/registry.ts create mode 100644 src/lib/skills/sandbox.ts create mode 100644 src/lib/skills/schemas.ts create mode 100644 src/lib/skills/types.ts create mode 100644 tests/unit/memory-extraction.test.mjs diff --git a/open-sse/handlers/chatCore.ts b/open-sse/handlers/chatCore.ts index d8a46133d3..89f4ee52cc 100644 --- a/open-sse/handlers/chatCore.ts +++ b/open-sse/handlers/chatCore.ts @@ -90,6 +90,8 @@ import { import { resolveStreamFlag, stripMarkdownCodeFence } from "../utils/aiSdkCompat.ts";
