  • Tasks that involve Technical documentation

What it does

Readme is an agent skill from LennartHennigs/Button2. Audit README.md against the current Button2 API and recent CHANGELOG entries, then apply any needed updates

Its SKILL.md is about 370 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Technical documentation, Changelog and release notes and Embedded systems. The repository describes itself as: Arduino/ESP button library that provides callback functions to track single, double, triple and long clicks. It also takes care of debouncing. The licence is MIT.

When your agent uses it

  • Tasks that involve Technical documentation
  • Tasks that involve Changelog and release notes
  • Tasks that involve Embedded systems

Example prompts

  • “/readme”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Gather context
  2. Identify gaps
  3. Propose changes
  4. Apply updates

What it can do on your machine

Read from SKILL.md and the folder at commit 2f8ba6a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Readme loads about 372 tokens when it runs. Until then it costs about 29 tokens; SKILL.md has 204 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~29
When it runs · the whole SKILL.md, loaded when a task matches
~372

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Audit README.md against the current Button2 API and recent CHANGELOG entries, then apply any needed updates

Audit and update README.md to reflect the current state of the library.

Step 1: Gather context

  • Read src/Button2.h — extract every public method signature and constant
  • Read the ## Unreleased and most recent versioned section of CHANGELOG.md
  • Read README.md in full

Step 2: Identify gaps

Compare the public API in Button2.h against what README documents. Flag:

  • Public methods present in the header but missing or outdated in README
  • Methods in README that no longer exist in the header
  • Default values or timing constants in README that differ from the header
  • New features mentioned in CHANGELOG that have no README coverage

Do not flag internal helpers, private methods, or test infrastructure.

Step 3: Propose changes

List each gap with a one-line description of what needs to change. If $ARGUMENTS contains "audit", stop here and show the list without editing.

Step 4: Apply updates

For each gap, edit README.md in place:

  • Match the existing style, formatting, and section structure exactly
  • For new API entries, insert them in the same section and format as adjacent entries
  • For removed entries, delete them cleanly without leaving stubs or comments
  • Keep code examples consistent with the Arduino/ESP conventions in the file (no STL, no smart pointers)

Report what was changed when done.

Questions about Readme

What does Readme do?

Audit README.md against the current Button2 API and recent CHANGELOG entries, then apply any needed updates. Readme is an agent skill from LennartHennigs/Button2.

When should I use Readme?

Readme fits situations like: tasks that involve Technical documentation; tasks that involve Changelog and release notes; tasks that involve Embedded systems.

How do I install Readme in Claude Code?

Run `npx skills add LennartHennigs/Button2 --skill readme -a claude-code`. Or copy the skill folder (.claude/skills/readme in LennartHennigs/Button2) into .claude/skills/readme in your project. Claude Code loads it when a task matches its description.

How do I install Readme in Codex?

Run `npx skills add LennartHennigs/Button2 --skill readme -a codex`. Or copy the skill folder (.claude/skills/readme in LennartHennigs/Button2) into .agents/skills/readme in your project. Codex loads it when a task matches its description.

Can I use Readme in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add LennartHennigs/Button2 --skill readme -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/readme, .gemini/skills/readme, .github/skills/readme and .opencode/skills/readme in your project.

What does Readme need to run?

SKILL.md names no scripts, command-line tools or credentials: Readme is instructions for the agent only.

Does Readme access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Readme safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Readme use?

Readme is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Readme use?

About 372 tokens (SKILL.md is roughly 1.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Readme?

Skills that share tags, products or a category with Readme: Commit (LennartHennigs/ESPRotary, 188 stars), Readme (LennartHennigs/ESPRotary, 188 stars), Simple English (moeru-ai/airi, 50k stars) and Ccb GitHub (SeemSeam/claude_codex_bridge, 3.6k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Readme?

LennartHennigs (a GitHub user) maintains it in LennartHennigs/Button2, which has 565 GitHub stars. The repository holds 4 skills in this directory. The repository was last updated on June 6, 2026.
