What it does

Tessie is an agent skill from win4r/MuseAI-Skills. Monitor a Tesla vehicle, inspect live state, and run explicit Tessie command endpoints.

Its SKILL.md is about 740 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `manifest.yaml`).

The repository describes itself as: muse.ai (Muse AI) skills and runtime snapshot: 68 skills, workflow guides, connector manifests. muse.ai 技能与运行环境文件;非官方存档 / Unofficial archive.

Example prompts

  • “/tessie”

Requirements

  • A credential in TESSIE_API_TOKEN

Workflow steps

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

  1. If VIN is not given, call vehicles and ask user to pick one when multiple exist.
  2. Use status or state before impactful commands when the current vehicle condition matters.
  3. honk, flash, remote_boombox, software-update scheduling or cancellation, and fleet telemetry configuration may proceed from a clear…
  4. Use command --command only for explicit Tessie command names. Do not invent a mandatory pre-wake flow or undocumented helper behavior.
  5. On HTTP or API errors, report status and body clearly. Common cases are 401, 408, and 503.
  6. Never print token values.
  7. Read results preserve Tessie's raw timestamps and add semantic UTC and

What it can do on your machine

Read from SKILL.md and the folder at commit 38bbb45. 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 (its code samples are bash).

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • dash.tessie.com

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • TESSIE_API_TOKEN

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

Context cost

Tessie loads about 738 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 360 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~24
When it runs · the whole SKILL.md, loaded when a task matches
~738

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 360 words (~738 tokens).
