timebuzzer-ledControl timeBuzzer hardware LED via MIDI — set color, effects (pulse, strobe, rainbow, fade), and semantic status signals.
Timebuzzer Led is an agent skill from glebis/claude-skills. Control timeBuzzer hardware LED via MIDI — set color, effects (pulse, strobe, rainbow, fade), and semantic status signals. Use when the user asks to change the buzzer LED color, signal status through the buzzer, or sync the buzzer with other lighting.
Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `README.md` and `scripts/buzzer_led.py`).
The repository describes itself as: Collection of Claude Code skills for enhanced AI workflows. The licence is MIT.
Read from SKILL.md and the folder at commit 7524dff. It shows what the files ask for, not the result of running them.
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.
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3pipFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Timebuzzer Led loads about 720 tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 163 words of instructions outside code blocks.
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.
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); the scripts in this folder are not scanned.

Control timeBuzzer hardware LED via MIDI — set color, effects (pulse, strobe, rainbow, fade), and semantic status signals. Timebuzzer Led is an agent skill from glebis/claude-skills. Control timeBuzzer hardware LED via MIDI — set color, effects (pulse, strobe, rainbow, fade), and semantic status signals.
Timebuzzer Led fits situations like: the user asks to change the buzzer LED color; signal status through the buzzer; sync the buzzer with other lighting.
Run `npx skills add glebis/claude-skills --skill timebuzzer-led -a claude-code`. Or copy the skill folder (timebuzzer-led in glebis/claude-skills) into .claude/skills/timebuzzer-led in your project. Claude Code loads it when a task matches its description.
Run `npx skills add glebis/claude-skills --skill timebuzzer-led -a codex`. Or copy the skill folder (timebuzzer-led in glebis/claude-skills) into .agents/skills/timebuzzer-led in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add glebis/claude-skills --skill timebuzzer-led -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/timebuzzer-led, .gemini/skills/timebuzzer-led, .github/skills/timebuzzer-led and .opencode/skills/timebuzzer-led in your project.
Going by SKILL.md and its folder, Timebuzzer Led needs Python for the scripts in its folder and the command-line tools its instructions call (python3 and pip). Our summary lists: Python 3.
SKILL.md contains no URLs. Its commands use pip, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
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. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Timebuzzer Led is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 720 tokens (SKILL.md is roughly 2.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Timebuzzer Led: Color Expert (nexu-io/open-design, 100k stars), Music Midi (ruvnet/ruflo, 74k stars), Run Devicelab With Led (flutter/flutter, 179k stars) and Color Blocking (sickn33/agentic-awesome-skills, 47k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
