What it does

Roadrunner Scenario Authoring is an agent skill from matlab/matlab-agentic-toolkit. Programmatically author RoadRunner scenarios from MATLAB using roadrunnerAPI. Use when adding actors, creating routes, building scenario logic (phases, conditions, actions), placing vehicles/pedestrians, defining cut-in/crossing/ follow scenarios, or any programmatic scenario creation in RoadRunner. Triggers on: roadrunnerAPI, scenario authoring, add actor, create route, phase logic, cut-in scenario, pedestrian crossing, scenario from MATLAB.

Its SKILL.md is about 6.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 17 other files, including scripts and reference files (for example `manifest.yaml`, `references/actions-and-conditions.md` and `references/asset-catalog.md`).

The repository describes itself as: The MATLAB Agentic Toolkit brings proven MATLAB capabilities to AI agents, making engineering and scientific workflows agent-ready.

When your agent uses it

  • Creating routes
  • Building scenario logic (phases
  • Placing vehicles/pedestrians
  • Defining cut-in/crossing/ follow scenarios

Example prompts

  • “/roadrunner-scenario-authoring”

Workflow steps

8 steps, taken from the step headings in SKILL.md.

  1. Ensure Session
  2. Initialize Scenario
  3. Scene Awareness
  4. Add Actors
  5. Position Actors (Anchoring)
  6. Create Routes (When Needed)
  7. Build Phase Logic
  8. Validate and Report

What it can do on your machine

Read from SKILL.md and the folder at commit 69e71df. 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 6 files in scripts/, which the agent can run.

    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

Roadrunner Scenario Authoring loads about 6.7k tokens when it runs, and up to ~21k if it reads all its reference files. Until then it costs about 119 tokens; SKILL.md has 2,512 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~119
When it runs · the whole SKILL.md, loaded when a task matches
~6.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~21k

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); the scripts in this folder 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 2,512 words (~6,681 tokens).

“Programmatically create RoadRunner scenarios from MATLAB: actors, routes, phase logic, and validation — all via roadrunnerAPI.”
