Serial

What it does

When your agent uses it

• The user mentions serial
• Binary protocol debugging
• Recording UART evidence

Example prompts

• “/serial”

Requirements

• Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

1. 1Scan ports and confirm the expected adapter.
2. 2Monitor for reset/banner output.
3. 3If no output, verify baud rate, TX/RX direction, voltage domain, firmware UART init, and whether the current HEX was flashed.
4. 4Log evidence before changing firmware.
5. 5For commands, send one minimal request and wait for response.

What it can do on your machine

Read from SKILL.md and the folder at commit 56ab07d. 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

  Ships 7 files in scripts/ (Python), which the agent can run.

  Shell commands in SKILL.md call:

  • python

  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

Serial loads about 754 tokens when it runs, and up to ~977 if it reads all its reference files. Until then it costs about 92 tokens; SKILL.md has 239 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~92

When it runs · the whole SKILL.md, loaded when a task matches

~754

With references · SKILL.md plus every file in references/, read only if the agent opens them

~977

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

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.

description

Embedded serial-port debugging skill. Use when the user mentions serial, COM port, UART, baud rate, AT commands, Hex stream, serial logs, MCU output, binary protocol debugging, monitoring, sending data, or recording UART evidence. Provides scripts to scan ports, monitor text, send text/hex data, dump hex streams, record logs, and optionally use a serial mux.
