# 食物数据库查询技能

## Overview

This public intake copy packages `plugins/antigravity-awesome-skills/skills/food-database-query` from `https://github.com/sickn33/antigravity-awesome-skills` into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the `external_source` block in `metadata.json` plus `ORIGIN.md` as the provenance anchor for review.

# 食物数据库查询技能 技能名称: Food Database Query 技能类型: 数据查询与分析 创建日期: 2026-01-06 版本: v1.0 ---

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: 技能概述, 数据源, 功能模块, 数据结构, RDA参考值, 集成功能.

## When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

- 需要查询食物营养成分、比较食物差异或做营养计算时使用。
- 任务涉及食物数据库检索、食物推荐、份量换算或分类筛选。
- 需要基于结构化食物数据生成分析结果而不是自由文本建议时使用。
- Use when the request clearly matches the imported source intent: Food Database Query.
- Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
- Use when provenance needs to stay visible in the answer, PR, or review packet.

## Operating Table

| Situation | Start here | Why it matters |
| --- | --- | --- |
| First-time use | `metadata.json` | Confirms repository, branch, commit, and imported path through the `external_source` block before touching the copied workflow |
| Provenance review | `ORIGIN.md` | Gives reviewers a plain-language audit trail for the imported source |
| Workflow execution | `SKILL.md` | Starts with the smallest copied file that materially changes execution |
| Supporting context | `SKILL.md` | Adds the next most relevant copied source file without loading the entire package |
| Handoff decision | `## Related Skills` | Helps the operator switch to a stronger native skill when the task drifts |

## Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
2. Read the overview and provenance files before loading any copied upstream support files.
3. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
4. Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
5. Validate the result against the upstream expectations and the evidence you can point to in the copied files.
6. Escalate or hand off to a related skill when the work moves out of this imported workflow's center of gravity.
7. Before merge or closure, record what was used, what changed, and what the reviewer still needs to verify.

---

## Examples

### Example 1: Ask for the upstream workflow directly

```text
Use @food-database-query-v2 to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.
```

**Explanation:** This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

### Example 2: Ask for a provenance-grounded review

```text
Review @food-database-query-v2 against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.
```

**Explanation:** Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

### Example 3: Narrow the copied support files before execution

```text
Use @food-database-query-v2 for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.
```

**Explanation:** This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

### Example 4: Build a reviewer packet

```text
Review @food-database-query-v2 using the copied upstream files plus provenance, then summarize any gaps before merge.
```

**Explanation:** This is useful when the PR is waiting for human review and you want a repeatable audit packet.



## Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

- Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
- Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
- Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
- Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
- Treat generated examples as scaffolding; adapt them to the concrete task before execution.
- Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.



## Troubleshooting

### Problem: The operator skipped the imported context and answered too generically

**Symptoms:** The result ignores the upstream workflow in `plugins/antigravity-awesome-skills/skills/food-database-query`, fails to mention provenance, or does not use any copied source files at all.
**Solution:** Re-open `metadata.json`, `ORIGIN.md`, and the most relevant copied upstream files. Check the `external_source` block first, then restate the provenance before continuing.

### Problem: The imported workflow feels incomplete during review

**Symptoms:** Reviewers can see the generated `SKILL.md`, but they cannot quickly tell which references, examples, or scripts matter for the current task.
**Solution:** Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

### Problem: The task drifted into a different specialization

**Symptoms:** The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better.
**Solution:** Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

## Additional Resources

Use this support matrix and the linked files below as the operator packet for this imported skill. They should reflect real copied source material, not generic scaffolding.

| Resource family | What it gives the reviewer | Example path |
| --- | --- | --- |
| `references` | copied reference notes, guides, or background material from upstream | `references/n/a` |
| `examples` | worked examples or reusable prompts copied from upstream | `examples/n/a` |
| `scripts` | upstream helper scripts that change execution or validation | `scripts/n/a` |
| `agents` | routing or delegation notes that are genuinely part of the imported package | `agents/n/a` |
| `assets` | supporting assets or schemas copied from the source package | `assets/n/a` |

    recommendations = []

    for food in database:
        value = food.nutrition_per_100g[nutrient]

        # 筛选符合条件
        if min_value and value < min_value:
            continue
        if max_value and value > max_value:
            continue

        recommendations.append({
            "food": food,
            "value": value,
            "rda_percent": (value / RDA[nutrient]) * 100
        })

### 4. 自动营养计算 (Auto Nutrition Calculation)

#### 4.1 食物识别

**输入解析**:
```python
def parse_food_input(text):
    # 示例: "燕麦粥 1杯 + 鸡蛋 1个 + 牛奶 250ml"

    foods = []
    portions = []

    # 识别食物名称
    for item in text.split("+"):
        food_name = extract_food_name(item)  # "燕麦粥"
        portion = extract_portion(item)      # "1杯"

        # 标准化食物名称
        standard_name = normalize_food_name(food_name)  # "燕麦"

        # 查询数据库
        food_data = query_database(standard_name)

        foods.append(food_data)
        portions.append(parse_portion(portion))

    return foods, portions
```

#### 4.2 份量转换

**常见份量**:
- "1杯": 240ml (液体) 或 重量依据食物
- "1个": 鸡蛋50g, 苹果150g
- "1片": 面包30g
- "100g": 直接使用

**份量数据库**:
```json
{
  "common_portions": [
    {
      "amount": 1,
      "unit": "个",
      "weight_g": 50,
      "description": "1个大号鸡蛋"
    },
    {
      "amount": 1,
      "unit": "杯",
      "weight_g": 240,
      "description": "1杯牛奶"
    }
  ]
}
```

#### 4.3 营养计算

**计算公式**:
```python
def calculate_nutrition(food, portion_grams):
    nutrition = {}

    for nutrient, value_per_100g in food.nutrition_per_100g.items():
        # 按100g比例计算
        nutrition[nutrient] = (value_per_100g * portion_grams) / 100

    return nutrition
```

#### 4.4 烹饪影响修正

**考虑因素**:
- 煮熟后重量变化
- 维生素损失
- 营养素保留率

**示例**:
- 燕麦生:100g → 煮熟:约300g (3倍重量)
- 维生素保留: 煮熟保留60-80%

---

### 5. 智能搜索 (Smart Search)

#### 5.1 别名匹配

**支持同义词**:
- "燕麦" = "燕麦片" = "oats" = "rolled oats"
- "西兰花" = "绿花菜" = "broccoli"

**匹配算法**:
```python
def find_food(name):
    # 1. 精确匹配主名称
    if name in database:
        return database[name]

    # 2. 匹配别名
    for food in database:
        if name in food.aliases:
            return food

    # 3. 模糊匹配
    matches = fuzzy_search(name)
    if matches:
        return matches[0]

    return None
```

#### 5.2 拼写纠错

**编辑距离算法**:
```python
def fuzzy_search(name, max_distance=2):
    matches = []

    for food in database:
        # 计算编辑距离
        distance = levenshtein_distance(name, food.name)

        if distance <= max_distance:
            matches.append((food, distance))

    # 按距离排序
    return sorted(matches, key=lambda x: x[1])
```
