embedded-library-entry

embedded-library-entry is a skill for Claude Code, Codex from easyzoom/aix-skills. It costs 28 tokens per session (1,821 once invoked), scanned A, original, MIT.

A starting point for adding or debugging third-party C libraries on microcontrollers. It first identifies the library, hardware, runtime, build system, resource limits, and platform-specific code it needs.

In plain words
What is it for?
Use it to route work involving embedded libraries for storage, logging, filesystems, protocols, user interfaces, parsers, buttons, timers, or state machines.
Why use it?
It prevents choosing the wrong integration approach when a library must work with bare-metal firmware or an operating system. It also exposes missing drivers and services such as timing, storage, locks, or memory allocation.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

embedded-library-entry 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 9d ago.

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.

Embedded Library Entry

Overview

Use this skill as the entry point for MCU library integration work. Classify the library type, target platform, runtime model, resource limits, and required porting layer before routing to a specific library skill.

When To Use

Use this skill when:

  • The user wants to add, port, configure, or debug an embedded C library.
  • The task involves MCU storage, logging, crash diagnosis, shell commands, filesystems, protocol stacks, UI, parsers, buttons, timers, queues, or state machines.
  • The target may be bare metal, RTOS-based, or resource-constrained.

Do not use this skill when the problem is only board bring-up, flashing, serial logs, or architecture faults. Use the embedded debug skills first.

First Questions

Ask only what is needed to route:

  • Library name and version or source repository.
  • Target MCU/SoC, compiler, and build system.
  • Runtime model: bare metal, FreeRTOS, RT-Thread, Zephyr, Linux, or unknown.
  • Memory/storage resources: RAM, flash, block device, filesystem, heap, stack, and whether dynamic allocation is allowed.
  • Existing porting layer: file I/O, flash driver, UART, timebase, mutex, malloc, display, network, or shell transport.
  • Current task: first integration, compile error, link error, runtime failure, performance issue, or data corruption.

embedded-library-entry is a skill published in the GitHub repository easyzoom/aix-skills (31 stars, last pushed 1mo ago), licensed MIT. It adds 28 tokens to every session and 1,821 once invoked, about $0.0001 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 2026-08-30.
