# Feature Specification: [FEATURE NAME]
|
||
|
||
**Feature Branch**: `[###-feature-name]`
|
||
**Created**: [DATE]
|
||
**Status**: Draft
|
||
**Input**: User description: "$ARGUMENTS"
|
||
|
||
> 宪法对齐（v1.0.0）：
|
||
> - 保持“轻量、匿名、CLI 多仓代理”定位：不得引入 Web UI、账号体系或与代理无关的范围。
|
||
> - 方案必须基于 Go 1.25+ 单二进制，依赖仅限 Fiber、Viper、Logrus/Lumberjack 及必要标准库。
|
||
> - 所有行为由单一 `config.toml` 控制；若需新配置项，需在规范中说明字段、默认值与迁移策略。
|
||
> - 设计需维护缓存优先 + 流式传输路径，并描述命中/回源/失败时的日志与观测需求。
|
||
> - 验收必须包含配置解析、缓存读写、Host Header 绑定等测试与中文注释交付约束。

||
## User Scenarios & Testing *(mandatory)*
|
||
|
||
<!--
|
||
IMPORTANT: User stories should be PRIORITIZED as user journeys ordered by importance.
|
||
Each user story/journey must be INDEPENDENTLY TESTABLE - meaning if you implement just ONE of them,
|
||
you should still have a viable MVP (Minimum Viable Product) that delivers value.
|
||
|
||
Assign priorities (P1, P2, P3, etc.) to each story, where P1 is the most critical.
|
||
Think of each story as a standalone slice of functionality that can be:
|
||
- Developed independently
|
||
- Tested independently
|
||
- Deployed independently
|
||
- Demonstrated to users independently
|
||
-->
|
||
|
||
### User Story 1 - [Brief Title] (Priority: P1)
|
||
|
||
[Describe this user journey in plain language]
|
||
|
||
**Why this priority**: [Explain the value and why it has this priority level]
|
||
|
||
**Independent Test**: [Describe how this can be tested independently - e.g., "Can be fully tested by [specific action] and delivers [specific value]"]
|
||
|
||
**Acceptance Scenarios**:
|
||
|
||
1. **Given** [initial state], **When** [action], **Then** [expected outcome]
|
||
2. **Given** [initial state], **When** [action], **Then** [expected outcome]
|
||
|
||

|
||
|
||
### User Story 2 - [Brief Title] (Priority: P2)
|
||
|
||
[Describe this user journey in plain language]
|
||
|
||
**Why this priority**: [Explain the value and why it has this priority level]
|
||
|
||
**Independent Test**: [Describe how this can be tested independently]
|
||
|
||
**Acceptance Scenarios**:
|
||
|
||
1. **Given** [initial state], **When** [action], **Then** [expected outcome]
|
||

|
||
|
||
### User Story 3 - [Brief Title] (Priority: P3)
|
||
|
||
[Describe this user journey in plain language]
|
||
|
||
**Why this priority**: [Explain the value and why it has this priority level]
|
||
|
||
**Independent Test**: [Describe how this can be tested independently]
|
||
|
||
**Acceptance Scenarios**:
|
||
|
||
1. **Given** [initial state], **When** [action], **Then** [expected outcome]
|
||
|
||
---
|
||
|
||
[Add more user stories as needed, each with an assigned priority]
|
||
|
||
### Edge Cases
|
||
|
||
<!--
|
||
ACTION REQUIRED: The content in this section represents placeholders.
|
||
Fill them out with the right edge cases.
|
||
-->
|
||
|
||
- What happens when [boundary condition]?
|
||
- How does system handle [error scenario]?
|
||
|
||
## Requirements *(mandatory)*
|
||
|
||
<!--
|
||
ACTION REQUIRED: The content in this section represents placeholders.
|
||
Fill them out with the right functional requirements.
|
||
-->
|
||
|
||
### Functional Requirements
|
||
|
||
- **FR-001**: System MUST [specific capability, e.g., "allow users to create accounts"]
|
||
- **FR-002**: System MUST [specific capability, e.g., "validate email addresses"]
|
||
- **FR-003**: Users MUST be able to [key interaction, e.g., "reset their password"]
|
||
- **FR-004**: System MUST [data requirement, e.g., "persist user preferences"]
|
||
- **FR-005**: System MUST [behavior, e.g., "log all security events"]
|
||
|
||
*Example of marking unclear requirements:*
|
||
|
||
- **FR-006**: System MUST authenticate users via [NEEDS CLARIFICATION: auth method not specified - email/password, SSO, OAuth?]
|
||
- **FR-007**: System MUST retain user data for [NEEDS CLARIFICATION: retention period not specified]
|
||
|
||
### Key Entities *(include if feature involves data)*
|
||
|
||
- **[Entity 1]**: [What it represents, key attributes without implementation]
|
||
- **[Entity 2]**: [What it represents, relationships to other entities]
|
||
|
||
## Success Criteria *(mandatory)*
|
||
|
||
<!--
|
||
ACTION REQUIRED: Define measurable success criteria.
|
||
These must be technology-agnostic and measurable.
|
||
-->
|
||
|
||
### Measurable Outcomes
|
||
|
||
- **SC-001**: [Measurable metric, e.g., "Users can complete account creation in under 2 minutes"]
|
||
- **SC-002**: [Measurable metric, e.g., "System handles 1000 concurrent users without degradation"]
|
||
- **SC-003**: [User satisfaction metric, e.g., "90% of users successfully complete primary task on first attempt"]
|
||
- **SC-004**: [Business metric, e.g., "Reduce support tickets related to [X] by 50%"]
