  • Prompt-injection patterns
  • Secret / credential exfiltration
  • Dangerous shell & filesystem operations
  • Untrusted network calls
  • Known-malicious package signatures

What it can access

  • Network access No
  • Filesystem access No
  • Shell / process execution No
  • Environment & secrets No
  • Dynamic code execution No

From automated source analysis of v0.1.0. “Used” means the capability is present in the source — more access means more to trust, not that it’s unsafe.

Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

GCC 嵌入式工程构建

本 skill 提供基于 CMake + arm-none-eabi-gcc 的嵌入式工程发现、preset 枚举、配置生成、增量编译、全量重建、清理和 ELF 大小分析能力。

范围说明:当前仅支持 CMake 型 GCC 嵌入式工程,不覆盖纯 Makefile 工程。

配置

环境级配置(skill/config.json)

skill 目录下的 config.json 包含环境级配置,首次使用前确认 cmake_exe 路径正确:

{
  "cmake_exe": "cmake",
  "toolchain_prefix": "arm-none-eabi-",
  "toolchain_path": "",
  "operation_mode": 1
}
  • cmake_exe:cmake 可执行文件路径,默认从 PATH 查找
  • toolchain_prefix:工具链前缀,默认 arm-none-eabi-,用于定位 size 等工具
  • toolchain_path:工具链 bin 目录,为空时从 PATH 查找
  • operation_mode1 直接执行 / 2 输出风险摘要但不阻塞 / 3 执行前确认

工程级配置(workspace/.embeddedskills/config.json)

工程级共享配置统一保存在工作区的 .embeddedskills/config.json 中:

{
  "gcc": {
    "project": "",
    "preset": "",
    "log_dir": ".embeddedskills/build"
  }
}
  • project:默认工程路径(相对 workspace),构建成功后会自动更新
  • preset:默认 CMake preset 名称,构建成功后会自动更新
  • log_dir:构建日志输出目录,默认 .embeddedskills/build

参数解析优先级

参数解析顺序(从高到低):

  1. CLI 显式参数
  2. 环境级配置(skill/config.json)
  3. 工程级配置(.embeddedskills/config.json)
  4. state.json(上次构建记录)
  5. 搜索/询问

冲突解决规则:同一参数存在多个来源时,以序号最小的来源为准;高序号来源仅在低序号来源未提供该参数时生效。例如:CLI 已指定 --preset Debug,则忽略 state.json 中记录的上次 preset。

子命令

| 子命令 | 用途 | 风险 | |--------|------|------| | scan | 搜索当前目录下的 CMake 嵌入式工程 | 低 | | presets | 列出 CMakePresets.json 中的 configure/build preset | 低 | | configure | 执行 cmake --preset 生成构建系统 | 中 | | build | 增量编译 cmake --build | 中 | | rebuild | 清理后全量重建 | 中 | | clean | 清理构建目录 | 高 | | size | 分析 ELF 文件大小(text/data/bss 和内存使用) | 低 |

执行流程

  1. 读取 config.json,确认 cmake_exe 路径有效
  2. 未提供有效子命令时默认执行 scan
  3. 未提供工程路径时先执行 scan 搜索工程
  4. 发现多个工程或多个 preset 时列出选项让用户选择,绝不自动猜测
  5. configure/build/rebuild/cleanoperation_mode 决定是否需要确认
  6. build 前自动检测是否已 configure,未配置时提示先执行 configure
  7. build/rebuild 成功后返回 elf_file,供 jlink/openocd 继续使用
  8. size 默认分析最近一次构建产物的 .elf 文件

脚本调用

skill 目录下有三个 Python 脚本,使用标准库实现,无额外依赖。

gcc_project.py — 工程扫描与 preset 枚举

# 扫描工程
python /scripts/gcc_project.py scan --root  --json

# 列出 preset
python /scripts/gcc_project.py presets --project  --json

gcc_build.py — 配置 / 编译 / 重建 / 清理

python /scripts/gcc_build.py  \
  --cmake  \
  --project  \
  --preset  \
  --log-dir  \
  --json

gcc_size.py — ELF 大小分析

# 基本分析
python /scripts/gcc_size.py analyze \
  --elf  \
  --toolchain-prefix arm-none-eabi- \
  --linker-script  \
  --json

# 对比分析
python /scripts/gcc_size.py compare \
  --elf  \
  --compare  \
  --toolchain-prefix arm-none-eabi- \
  --json

输出格式

所有脚本以 JSON 格式返回,基础字段为 status(ok/error)、actionsummarydetails,并可能附带 contextartifactsmetricsstatenext_actionstiming

成功示例:

{
  "status": "ok",
  "action": "build",
  "summary": "build 成功,errors=0 warnings=2",
  "details": { "project": "...", "preset": "Debug", "build_dir": "...", "elf_file": "...", "log_file": "..." },
  "metrics": { "errors": 0, "warnings": 2, "flash_bytes": 99328, "ram_bytes": 46080 }
}

错误示例:

{
  "status": "error",
  "action": "build",
  "error": { "code": "not_configured", "message": "构建目录不存在,请先执行 configure" }
}

核心规则

  • 不修改 CMakeLists.txt 或任何 CMake 配置文件
  • 当前 skill 仅覆盖 CMake 型 GCC 工程,不对纯 Makefile 工程做识别和构建
  • 不自动猜测工程路径或 preset,有歧义时必须询问用户
  • 参数解析优先级为:CLI 显式参数 > 环境级配置 > 工程级配置 > .embeddedskills/state.json > 搜索/询问
  • clean 不在自动流程中隐式执行
  • 构建失败时优先展示首个错误和日志文件路径
  • 结果回显中始终包含工程名、preset 名、构建目录路径;构建成功时优先回显 elf_file
