What problem does it solve? Chinese formal technical documents like bid proposals and design reports often suffer from vague, buzzword-heavy content lacking selection rationale, mechanism details, and metric support. This Skill enforces a structured writing workflow with a searchable built-in knowledge base, project material retrieval, and a six-question depth protocol to produce verifiable, substantive documents. ## Core Features & Use Cases - Scenario Routing: Matches the request to one of five scenes (technical proposal, design report, test report, weekly report, general fallback) and loads the corresponding reference specification before writing. - Dual-Source Retrieval: Selectively reads matched chunks from a 46-file built-in knowledge base (microservices, big data, IoT, GJB 438C templates) while fully reading user project materials placed in a local 素材库/ directory, indexed by a zero-argument Python script. - Depth Writing Protocol: Every key technical point must answer six questions covering problem, selection rationale, mechanism and data flow, engineering implementation, verification, and risk, with banned-word lists and pre-delivery review checklists. - Use Case: When asked to write a technical bid for a government supervision platform, the Skill loads the proposal reference, indexes project materials, retrieves relevant knowledge cards, and writes zero-bullet-point narrative sections that respond to tender clauses with real metrics. ## Quick Start Ask the assistant to use technical-proposal-expert to write a technical bid proposal, design report, test report, or weekly report for your project.
