Serial Studio data-hotpath rules and the 256 kHz throughput gate.

  • Development work in your project
  • SKILL.md covers Data flow, Hard rules, Block publication, time rings… and Measure, don't guess
  • Calls python

What it does

Ss Hotpath is an agent skill from Serial-Studio/Serial-Studio. Serial Studio data-hotpath rules and the 256 kHz throughput gate. Use BEFORE editing or reviewing FrameReader, CircularBuffer, FrameBuilder, ConnectionManager, DeviceManager, or Dashboard frame-draw code — anything on the Driver → FrameReader → FrameBuilder → Dashboard path. Covers SPSC/pipeline-thread rules, DirectConnection requirement, the no-alloc/no-copy slot pool, source-owns-time, and how to measure throughput with --benchmark-hotpath. Invoke it explicitly: it is never loaded for you.

Its SKILL.md is about 3.1k 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. The repository describes itself as: Open-source telemetry dashboard. Supports UART, BLE, MQTT, Modbus, CAN Bus and more.

When your agent uses it

  • Development work in your project

Example prompts

  • “/ss-hotpath”

What it can do on your machine

Read from SKILL.md and the folder at commit 34c87a4. 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

    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

Ss Hotpath loads about 3.1k tokens when it runs. Until then it costs about 127 tokens; SKILL.md has 1,448 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~127
When it runs · the whole SKILL.md, loaded when a task matches
~3.1k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,448 words (~3,077 tokens).

“You are touching the highest-risk code in the repo. Read the target file in full first (doc/claude/architecture/dataflow.md has the full data-flow and threading model). These rules are non-negotiable; violating them causes silent frame drops, not compile errors.”
