Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00131 | $0.03176 |
| Opus 5 | $0.00066 | $0.01588 |
| Sonnet 5 | $0.00026 | $0.00635 |
| Haiku 4.5 | $0.00013 | $0.00318 |
Grade A, and why
embedded-dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 452 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Embedded Development Skill (OpenCode Edition)
Current Version: v3.2.0 (2026-04-13)
AI辅助嵌入式系统开发的专项技能，支持驱动开发、UI设计、硬件调试、问题诊断。采用渐进式加载架构，核心指令保持在SKILL.md，详细规范存放在references目录。
OpenCode 版本说明: 本 Skill 已适配 OpenCode，使用 OpenCode 内置工具和 MCP 扩展系统。
OpenCode Tools Used
Built-in Tools (OpenCode 内置工具)
| OpenCode Tool | Function |
|---|---|
read |
读取源代码和数据手册 |
write |
生成源代码和配置文件 |
edit |
修改现有代码 |
bash |
编译、烧录、串口监控 |
glob |

MCP Extension Tools (扩展工具)
| MCP Tool | Function | Install |
|---|---|---|
embedded_build |
统一编译命令包装 | mcp-server-embedded.py |
embedded_diagnose |
编译错误诊断 | mcp-server-embedded.py |
注: 如果未配置 MCP Server，可使用 bash 工具直接执行编译命令。
Quick Start for OpenCode
# 1. 安装 Skill
mkdir -p ~/.opencode/skills/embedded-dev
cp SKILL.md ~/.opencode/skills/embedded-dev/
cp -r references ~/.opencode/skills/embedded-dev/
# 2. (可选) 配置 MCP Server
# 参考 MCP-GUIDE.md
# 3. 开始嵌入式开发
"帮我配置 ESP32-S3 的 ST7789 LCD 驱动"
Workflow (OpenCode Edition)
Phase 1: Context Loading
Use OpenCode's read tool to load AGENTS.md:
read AGENTS.md
- If AGENTS.md missing → Use
writeto create template with project info - Store key config in OpenCode session
Phase 2: Task Planning
Use todowrite tool for task tracking:
todowrite todos=[{"content": "Configure SPI driver", "status": "pending", "priority": "high"}]
- Simple task → Execute directly
- Complex task → Decompose into subtasks
Phase 3: Code Generation
Use OpenCode tools for code operations:
read src/driver.c # 读取现有代码
write src/driver_new.c # 创建新文件
edit src/driver.c # 修改代码
- Check references/ for detailed specs
- Apply modular architecture patterns
Phase 4: Verification
Use OpenCode's bash tool for build-flash-monitor loop:
bash: idf.py build
bash: idf.py -p COM3 flash monitor
- On Error → Analyze output → Fix → Retry
- Use MCP
embedded_diagnosefor error analysis (if configured)
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

embedded-dev is a skill published in the GitHub repository lhbsaa/embedded-dev-skill (9 stars, last pushed 1mo ago), licensed MIT. It adds 131 tokens to every session and 3,176 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
