feat: add tech-diagram skill (Mermaid 技术图生成) (#18)

## 概述 / Summary

新增市场技能 **tech-diagram**:把自然语言描述转成品牌一致的技术图(架构图/流程图/时序图/状态机/ER/类图/思维导图),在
DesireCore 对话内复用现有 Mermaid 渲染管线即时渲染为 SVG。

Adds a market skill **tech-diagram** that turns natural-language
descriptions into brand-consistent technical diagrams, rendered inline
as SVG by the existing Mermaid pipeline in the DesireCore chat.

灵感来源 / Inspired by
[fireworks-tech-graph](https://github.com/yizhiyanhua-ai/fireworks-tech-graph)
的三个设计思路:语义词汇表即数据、风格系统化、领域 Pattern 内置——并落到 DesireCore 自己的 3+2 设计令牌与领域模型上。

## 改动 / Changes

- `skills/tech-diagram/SKILL.md` + `SKILL.zh-CN.md`:双语技能正文(强制风格规则 +
语义词汇表 + 输出约定)
- `skills/tech-diagram/references/semantic-vocabulary.md`:概念→Mermaid
形状→3+2 classDef 完整映射
- `skills/tech-diagram/references/templates.md`:4 个 DesireCore
领域模板(Agent 架构 / Delegate 6 模式 / 三层记忆 / 关系图谱)+ 时序图示例
- `builtin-skills.json`:加入 `tech-diagram`
- `manifest.json`:`version` 1.2.1→1.2.2,`stats.totalSkills`
21→22,`lastUpdated`

## 设计要点 / Design

- **风格一致性**:每张图以 `%%{init}%%` 注入品牌主题(覆盖对话全局暗色),用 5 个 `classDef` 绑定
DesireCore 3+2 配色(green/blue/purple + warning orange / error red)。
- **语义优于视觉**:Agent→六边形、系统/记忆→圆角/圆柱、决策→菱形;箭头编码主数据流/记忆写入/异步/层级/上报。
- **领域内置**:直接对照 `delegate.ts` / `conversation-memory.ts` /
`relations/projector.ts` 给出可套用模板。

## 验证 / Verification

-  `scripts/i18n/validate-i18n.py`:无 i18n 问题
-  用 app 同版本 **mermaid 11.15.0**(securityLevel: loose)解析 `templates.md`
全部 5 个图块,全部通过

# tech-diagram Skill
Turn a natural-language description into a brand-consistent technical diagram.
You write **Mermaid** in your reply; the DesireCore chat renders it inline as SVG.
The point of this skill is consistency: every diagram uses the same DesireCore
3+2 palette and the same semantic shape/arrow vocabulary, so diagrams look like
they belong to one product.
## When to Use
Use this skill for diagrams of **structure, flow, or relationships**:
architecture, flowchart, sequence, state machine, ER, class diagram, mind map.
Do NOT use it for photographic or illustrative pictures — route those to an
image-generation skill (e.g. dashscope-image-gen, minimax-image-gen).
## Mandatory Style Rules
These are non-negotiable. Violating them produces off-brand or unrendered diagrams.
1. **Every diagram MUST start with the brand `%%{init}%%` directive.** The chat's
global Mermaid theme is hardcoded to dark; the init directive overrides it per
diagram so output is light and brand-consistent. Use exactly:
```
%%{init: {'theme':'base','themeVariables':{'primaryColor':'#F0F5FF','primaryBorderColor':'#007AFF','primaryTextColor':'#1d1d1f','lineColor':'#6e6e73','fontFamily':'-apple-system,SF Pro Text,Noto Sans SC,sans-serif'}}}%%
```
2. **Color ONLY from the DesireCore 3+2 system via `classDef`.** Never use Mermaid
default colors or any non-3+2 hex. The five classes below are the only palette:
```
classDef agent fill:#F6F3FF,stroke:#AF52DE,color:#1d1d1f
classDef system fill:#F0F5FF,stroke:#007AFF,color:#1d1d1f
classDef biz fill:#F0FDF4,stroke:#34C759,color:#1d1d1f
classDef warn fill:#FFFBF0,stroke:#FF9500,color:#1d1d1f
classDef error fill:#FFF0F0,stroke:#FF3B30,color:#1d1d1f
```
Values come from the DesireCore app codebase (`app/theme/tokens/index.ts` —
green `#34C759` / blue `#007AFF` / purple `#AF52DE` / orange `#FF9500` / red
`#FF3B30` — and `cardBgColors` / `cardBorderColors`; these app paths are not in
this market repo). Pick the class by the same rule as `agent-colors.ts`:
system/generic → blue, knowledge/learning → purple, business/execution → green,
project-management/warning → orange, error → red.
3. **Use the semantic shapes below**, not arbitrary ones.
4. **Quote any node label that contains punctuation, parentheses, or `/`** to avoid
Mermaid parse errors, e.g. `A["Query / Retrieve"]`.
## Semantic Vocabulary
Shape carries meaning (see `references/semantic-vocabulary.md` for the full table):
| Concept | Mermaid shape | classDef |
|---------|---------------|----------|
| Agent / 智能体 | hexagon `id{{...}}` | agent (purple) |
| DesireCore core / system | rounded `id(...)` | system (blue) |
| LLM / model | rounded `id(⚡ ...)` | system (blue) |
| Business / execution node | rect `id[...]` | biz (green) |
| Memory / store | cylinder `id[(...)]` | system (blue) |
| User | stadium `id([...])` | biz (green) |
| Decision / branch | diamond `id{...}` | warn (orange) |
| External service | dashed `subgraph` | — |
## Arrow / Flow Encoding
| Flow | Mermaid edge |
|------|--------------|
| Primary data flow | `-->` solid |
| Memory write / persistence | `-.->` dotted |
| Async event | `-.->|async|` dotted + label |
| Feedback / retry loop | back-edge `-->` to an earlier node |
## Built-in Templates
Ready-to-use Mermaid for DesireCore's own patterns lives in
`references/templates.md`: **Agent architecture**, **Delegate 6 modes**,
**three-tier conversation memory** (active → recent L0/L1 → archive L2), and the
**relation graph** (6 edge types: delegate / mention / co_task / hierarchy /
seek_help / escalation). Adapt them to the user's subject instead of starting
from scratch.
## Output Convention
Emit the diagram directly in your reply inside a fenced code block whose info
string is `mermaid` (open the fence with three backticks immediately followed by
the word mermaid). The chat renders it to SVG automatically; on a syntax error it
falls back to showing the raw code (the `mermaid-fallback` path), so the source
MUST be valid. Keep node labels short — long text breaks the layout.
## Common Mistakes
- ❌ Omitting `%%{init}%%` → the diagram inherits the global dark theme.
- ❌ Hardcoding non-3+2 hex or Tailwind default colors instead of the `classDef`s.
- ❌ Overlong node labels that overflow the layout.
- ❌ Unquoted labels with `()`, `/`, or CJK punctuation → Mermaid parse failure.

# tech-diagram 技能
把自然语言描述转成品牌一致的技术图。你在回复中写 **Mermaid**DesireCore 对话会即时渲染为 SVG。本技能的核心价值是一致性每张图都用同一套 DesireCore 3+2 配色和同一套语义形状/箭头词汇表,让所有图看起来像出自同一个产品。
## 何时使用
用于**结构、流程或关系**类的图架构图、流程图、时序图、状态机、ER 图、类图、思维导图。
不要用它生成写实摄影或插画类图片——那类需求请转给文生图技能(如 dashscope-image-gen、minimax-image-gen
## 强制风格规则
以下规则不可妥协,违反会产出偏离品牌或无法渲染的图。
1. **每张图必须以品牌 `%%{init}%%` 指令开头。** 对话的全局 Mermaid 主题写死为暗色init 指令按图覆盖它,从而输出浅色且品牌一致。固定使用:
```
%%{init: {'theme':'base','themeVariables':{'primaryColor':'#F0F5FF','primaryBorderColor':'#007AFF','primaryTextColor':'#1d1d1f','lineColor':'#6e6e73','fontFamily':'-apple-system,SF Pro Text,Noto Sans SC,sans-serif'}}}%%
```
2. **配色只能取自 DesireCore 3+2 体系,通过 `classDef` 绑定。** 禁止使用 Mermaid 默认色或任何非 3+2 色值。下面五个 class 是唯一允许的色板:
```
classDef agent fill:#F6F3FF,stroke:#AF52DE,color:#1d1d1f
classDef system fill:#F0F5FF,stroke:#007AFF,color:#1d1d1f
classDef biz fill:#F0FDF4,stroke:#34C759,color:#1d1d1f
classDef warn fill:#FFFBF0,stroke:#FF9500,color:#1d1d1f
classDef error fill:#FFF0F0,stroke:#FF3B30,color:#1d1d1f
```
色值来自 DesireCore app 代码库(`app/theme/tokens/index.ts`green `#34C759` / blue `#007AFF` / purple `#AF52DE` / orange `#FF9500` / red `#FF3B30`,以及 `cardBgColors` / `cardBorderColors`;这些 app 路径不在本 market 仓库内)。选 class 的规则与 `agent-colors.ts` 一致:系统/通用→blue知识/学习→purple业务/执行→green项目管理/警示→orange错误→red。
3. **使用下面的语义形状**,不要随意选形状。
4. **标签含标点、括号或 `/` 时必须加引号**,避免 Mermaid 解析失败,例如 `A["查询 / 检索"]`。
## 语义词汇表
形状本身承载含义(完整表见 `references/semantic-vocabulary.md`
| 概念 | Mermaid 形状 | classDef |
|------|-------------|----------|
| Agent / 智能体 | 六边形 `id{{...}}` | agent (purple) |
| DesireCore 核心 / 系统 | 圆角 `id(...)` | system (blue) |
| LLM / 模型 | 圆角 `id(⚡ ...)` | system (blue) |
| 业务 / 执行节点 | 矩形 `id[...]` | biz (green) |
| 记忆 / 存储 | 圆柱 `id[(...)]` | system (blue) |
| 用户 | 体育场形 `id([...])` | biz (green) |
| 决策 / 分支 | 菱形 `id{...}` | warn (orange) |
| 外部服务 | 虚线 `subgraph` | — |
## 箭头与流编码
| 流类型 | Mermaid 边 |
|--------|-----------|
| 主数据流 | `-->` 实线 |
| 记忆写入 / 持久化 | `-.->` 点线 |
| 异步事件 | `-.->|async|` 点线 + 标签 |
| 反馈 / 重试循环 | 指回前序节点的回边 `-->` |
## 内置模板
DesireCore 自身 Pattern 的现成 Mermaid 放在 `references/templates.md`**Agent 架构图**、**Delegate 6 模式**、**三层对话记忆**active → recent L0/L1 → archive L2、**关系图谱**6 种边delegate / mention / co_task / hierarchy / seek_help / escalation。请基于这些模板改写为用户的主题而非从零开始。
## 输出约定
直接在回复中用栅栏代码块输出图info string 为 `mermaid`(用三个反引号紧跟单词 mermaid 开启栅栏)。对话会自动渲染为 SVG语法出错时会降级展示原始代码`mermaid-fallback` 路径),所以源码必须合法。节点标签要短——文字过长会撑坏布局。
## 常见错误
- ❌ 漏掉 `%%{init}%%` → 图会沿用全局暗色主题。
- ❌ 硬编码非 3+2 色值或 Tailwind 默认色,而非用 `classDef`。
- ❌ 节点标签过长撑爆布局。
- ❌ 含 `()`、`/` 或中文标点的标签未加引号 → Mermaid 解析失败。

# Semantic Vocabulary (语义词汇表)
The full mapping from concept → Mermaid shape → DesireCore 3+2 class. Shape and
color encode meaning, so a reader understands a diagram without a legend.
## The brand header (paste verbatim as the first line of every diagram)
```
%%{init: {'theme':'base','themeVariables':{'primaryColor':'#F0F5FF','primaryBorderColor':'#007AFF','primaryTextColor':'#1d1d1f','lineColor':'#6e6e73','fontFamily':'-apple-system,SF Pro Text,Noto Sans SC,sans-serif'}}}%%
```
## The 5 color classes (the only allowed palette)
```
classDef agent fill:#F6F3FF,stroke:#AF52DE,color:#1d1d1f
classDef system fill:#F0F5FF,stroke:#007AFF,color:#1d1d1f
classDef biz fill:#F0FDF4,stroke:#34C759,color:#1d1d1f
classDef warn fill:#FFFBF0,stroke:#FF9500,color:#1d1d1f
classDef error fill:#FFF0F0,stroke:#FF3B30,color:#1d1d1f
```
`fill` = `cardBgColors`, `stroke` = the 3+2 accent, `color` = `systemColors.label`
(`#1d1d1f`). Source of truth: `app/theme/tokens/index.ts` and
`app/theme/presets/agent-colors.ts` **in the DesireCore application codebase**
(where this skill runs) — these paths are not part of this market repository.
### Class selection rule (mirrors agent-colors.ts)
| Domain | Class | Accent |
|--------|-------|--------|
| System / generic (DesireCore core, infra, LLM) | system | blue `#007AFF` |
| Knowledge / learning (legal, writer, memory) | agent / system | purple `#AF52DE` |
| Business / execution (data, real-estate, code) | biz | green `#34C759` |
| Project management / warning / decision | warn | orange `#FF9500` |
| Error / failure | error | red `#FF3B30` |
Decorative-only colors `yellow #FFCC00` and `teal #5AC8FA` are for background
gradients elsewhere in the product — never use them in diagrams.
## Shape table
| Concept | Mermaid syntax | Class | Note |
|---------|----------------|-------|------|
| Agent / sub-agent | `id{{Name}}` (hexagon) | agent | the signature shape for an autonomous agent |
| DesireCore core / orchestrator | `id(Name)` (rounded) | system | central coordinator |
| LLM / model | `id(⚡ Model)` (rounded + ⚡) | system | ⚡ prefix marks an LLM call |
| Service / tool / skill | `id[Name]` (rect) | biz | a callable capability |
| Business / execution step | `id[Step]` (rect) | biz | a unit of work |
| Memory / store / DB | `id[(Store)]` (cylinder) | system | persistent state |
| User / external actor | `id([User])` (stadium) | biz | the human |
| Decision / branch | `id{Choice?}` (diamond) | warn | a fork in control flow |
| External service | `subgraph Ext [External]` ... `end` + `style Ext stroke-dasharray:4 3` | — | dashed boundary = outside the system |
## Arrow / flow encoding
| Flow type | Edge syntax | Meaning |
|-----------|-------------|---------|
| Primary data flow | `A --> B` | the main path |
| Memory write / persistence | `A -.-> B` | dotted = side-effect write |
| Async event | `A -.->|async| B` | dotted + label |
| Feedback / retry | `B --> A` (back-edge) | loop |
| Hierarchy / containment | `A --o B` | circle edge |
| Hard stop / escalation | `A --x B` | cross edge |
| Co-participation (equal peers) | `A === B` | thick link |
## Diagram-type cheatsheet
| User intent | Mermaid header |
|-------------|----------------|
| Architecture / data flow | `flowchart TD` or `flowchart LR` |
| Sequence / interaction over time | `sequenceDiagram` |
| State machine | `stateDiagram-v2` |
| ER / data model | `erDiagram` |
| Class / type model | `classDiagram` |
| Mind map | `mindmap` |
For `sequenceDiagram`, `classDiagram`, etc. that do not support `classDef`, still
keep the `%%{init}%%` brand header so the theme stays light and on-brand.

# Built-in Templates (内置模板)
Ready-to-use, brand-styled Mermaid for DesireCore's own architecture patterns.
Adapt the labels to the user's subject; keep the header and `classDef`s intact.
All four are verified to render.
> Note: file paths like `lib/...` and `app/...` cited below refer to the
> **DesireCore application codebase** where this skill runs at runtime — they do
> not exist in this market repository.
## 1. Agent architecture (Agent 架构图)
Mirrors the delegate / skills / memory layout (`lib/agent-service/builtin-tools/delegate.ts`).
```mermaid
%%{init: {'theme':'base','themeVariables':{'primaryColor':'#F0F5FF','primaryBorderColor':'#007AFF','primaryTextColor':'#1d1d1f','lineColor':'#6e6e73','fontFamily':'-apple-system,SF Pro Text,Noto Sans SC,sans-serif'}}}%%

## 2. Delegate 6 modes (Delegate 六种模式)
The unified delegate tool and its six execution modes.
```mermaid
%%{init: {'theme':'base','themeVariables':{'primaryColor':'#F0F5FF','primaryBorderColor':'#007AFF','primaryTextColor':'#1d1d1f','lineColor':'#6e6e73','fontFamily':'-apple-system,SF Pro Text,Noto Sans SC,sans-serif'}}}%%

```
## 3. Three-tier conversation memory (三层对话记忆)
active → recent (L0/L1) → archive (L2); writes are dotted
(`lib/schemas/agent-service/conversation-memory.ts`).
```mermaid
%%{init: {'theme':'base','themeVariables':{'primaryColor':'#F0F5FF','primaryBorderColor':'#007AFF','primaryTextColor':'#1d1d1f','lineColor':'#6e6e73','fontFamily':'-apple-system,SF Pro Text,Noto Sans SC,sans-serif'}}}%%

Recent[("recent: L0 / L1 summaries")]:::system
Archive[("archive: L2 full log")]:::system
New --> Active
Active -.->|compact| Recent
Recent -.->|archive after 180d| Archive
```
## 4. Relation graph (关系图谱6 种边)
The six edge types projected by `lib/agent-service/relations/projector.ts`, each
drawn with a distinct edge style. Edge weight decays over time (30-day half-life).
```mermaid
%%{init: {'theme':'base','themeVariables':{'primaryColor':'#F0F5FF','primaryBorderColor':'#007AFF','primaryTextColor':'#1d1d1f','lineColor':'#6e6e73','fontFamily':'-apple-system,SF Pro Text,Noto Sans SC,sans-serif'}}}%%

A1 -.->|mention| A3
A2 ===|co_task| A3
A2 --o|hierarchy| A1
A3 -->|seek_help| A1
A1 --x|escalation| U
```
## Other diagram types
For sequence / state / ER / class diagrams, keep the same `%%{init}%%` header for
a consistent light theme. Example sequence diagram:
```mermaid
%%{init: {'theme':'base','themeVariables':{'primaryColor':'#F0F5FF','primaryBorderColor':'#007AFF','primaryTextColor':'#1d1d1f','lineColor':'#6e6e73','fontFamily':'-apple-system,SF Pro Text,Noto Sans SC,sans-serif'}}}%%
