What problem does it solve?
Deep internet research often spans searching, verifying original sources, archiving links, and transcribing media, but mixing these stages in one step leads to unauthorized downloads, unverified claims, and lost evidence trails. This Skill acts as a single safety-first router that plans the research, then delegates each stage to the correct child Skill with explicit authorization gates.
Core Features & Use Cases
- Multi-Stage Routing: Directs requests to yichen-unified-search, yichen-content-archive, yichen-bookmarks-export, or yichen-asr based on task stage, never auto-archiving after a search.
- Horizontal-Vertical Research Protocol: Builds a dated research brief, generates bounded longitudinal and cross-sectional query workstreams via an offline planner, and assembles a claim-source evidence ledger with structural stop gates before any report is written.
- Backend Health Checks: Ships a read-only doctor script that verifies optional backends (AnySearch, Firecrawl, Zhihu CLI, Grok CLI, OpenCLI, ASR) without probing networks or reading credentials.
- Use Case: Ask for a deep analysis of a company's development history plus its current competitive landscape; the Skill plans dated workstreams, searches per region and language, verifies claims against opened original sources, and only produces a report when all evidence gates pass.
Quick Start
Ask the assistant to run a horizontal-and-vertical deep research analysis on a company or industry with a defined scope, and let it plan and route the work through this Skill.
