serialwrap

serialwrap is a skill for Claude Code, Codex from hamanpaul/serialwrap. It costs 137 tokens per session (13,112 once invoked), scanned B, original, no licence file.

A skill for coordinating multiple AI agents through a shared UART connection, which is a serial communication link often used with microcontrollers. It manages one writer at a time, records raw communication, preserves sessions, supports device handoff, and can help with firmware flashing.

In plain words
What is it for?
Use it to run UART commands, collect device state, coordinate several agents, export UART evidence, hand a device to an external tool such as minicom or a firmware flasher, or work alongside a person using minicom.
Why use it?
It prevents agents and people from sending conflicting commands to the same device and keeps a consistent record of what happened.

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 B, and why

serialwrap scanned grade B with 2 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 3d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- **舊安裝要手動補**：`serialwrap setup` 不覆寫既有的 `~/.config/serialwrap/profiles/*.yaml`（只有 `setup --force` 會覆蓋，連本機改動一併蓋掉；systemd-system 模式則由 setup 以 sudo 把出貨 profile 複製進 `/etc/serialwrap/profiles`，同名檔會被蓋掉），升級後舊 profile 沒有這個欄位，ask

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- **大檔走網路通道，不走 UART**：firmware image 這類檔案，只要 DUT 有 SSH／TFTP／HTTP 可達，一律用 SCP／TFTP 傳輸，serialwrap 只負責控制面（以 `cmd submit` 觸發板端的 `scp`／`tftp`／`wget` 並觀察結果）。實測一顆 81 MB image 走 SCP 經 LAN 數秒完成；同一顆走 UART 即使通道完全穩定也需兩小時以上。

What this file has done since we first saw it

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.
