library-selection

library-selection is a skill for Claude Code from wedsamuel1230/arduino-skills. It costs 57 tokens per session (566 once invoked), scanned A, original, MIT.

A process for choosing, replacing, pinning, or reviewing software libraries for Arduino, ESP32, RP2040, C++, or vendor frameworks. It checks whether a library fits the board, framework, APIs, hardware, memory limits, license, and maintenance needs.

In plain words
What is it for?
Use it to compare candidate libraries, verify their source and supported versions, check dependencies and hardware behavior, select a fixed version, and test a minimal example.
Why use it?
A library that compiles may still use the wrong pins, timers, bus settings, memory model, or board assumptions. This process reduces compatibility, security, and maintenance surprises.

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

library-selection 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Library Selection

Treat a library as part of the firmware and hardware contract. A popular package that compiles for one architecture may still use incompatible pins, timers, memory, bus assumptions, or APIs on another.

Intake

Record exact board/module, architecture, Arduino core or vendor SDK, compiler, toolchain, required API, bus/pin constraints, memory budget, license boundary, update policy, and whether the device is connected or field-updatable.

Process

  1. Find the upstream source, release/tag, license, supported architectures, and framework instructions. Prefer primary repositories and current release notes.
  2. Compare candidate API fit, board variants, transitive dependencies, flash/ SRAM/heap impact, blocking behavior, concurrency, bus/pull-up assumptions, and error/recovery behavior.
  3. Check open issues and maintenance signals without treating stars or install count as compatibility proof.
  4. Select a pinned version, record provenance and rationale, and document unsupported board/framework branches.
  5. Run a minimal compile fixture, then a simulated or target behavior check.

Anti-rationalization

Shortcut Response
"It has many installs." Verify architecture, core version, API, and hardware contract.
"The newest version is best." Read release notes, compatibility, footprint, and regression history.
"The I2C scanner found it." Test library initialization, register reads, timing, and error paths.
"It worked on AVR." Recheck ESP32/S3/Pico architecture, pins, timers, and memory.
"The dependency is only a helper." Include transitive code and license/security review.

Verification

  • Candidate comparison contains source, version, architecture, and license.
  • Minimal compile output names the exact FQBN/environment and dependency resolution.
  • Memory delta and one runtime/simulation behavior result are recorded.
  • Connected devices have a dependency update and secret-handling plan.

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.
