# FineReport 数据探测

## Overview

Use this skill to turn remote datasource metadata into evidence for CPT or FVS editing. It is the only standard path for connection lookup and SQL preview.

## Inputs

- `.codex/fr-config.json`
- Confirmed target datasource or SQL question
- Remote Decision endpoint from current project config

## Execution

- macOS / Linux: `python3 .codex/skills/fr-db/scripts/run.py list-connections`
- Windows: `py .codex\\skills\\fr-db\\scripts\\run.py list-connections`

## Example Index

- `EXAMPLES.md`
  - 先看这里，按“接口范围 / CPT 数据集 / FVS 数据集”选入口
- `references/decision-http.md`
  - 需要确认 Decision HTTP 接口边界或登录载荷时看这个

## Expected Evidence

- Connection list summary
- SQL preview or dataset preview result
- Field list or dataset XML snippet
- Impact statement for the next CPT/FVS edit

## Failure Handling

- Do not invent connection names
- Do not continue with guessed columns
- Surface HTTP errors directly instead of masking them
