What it does
Generate Requirement Drafts is an agent skill from matlab/simulink-agentic-toolkit. Generates draft requirements from Simulink models. Use when drafting or updating requirement artifacts from a model. Prefers Requirements Toolbox (.slreqx) when available; falls back to structured YAML.
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files and assets (for example `assets/requirements.yaml`, `manifest.yaml` and `references/slreq-patterns.md`).
It sits in Testing & QA. The repository describes itself as: The Simulink Agentic Toolkit gives your AI agent both the tools and the expertise to work effectively with Simulink and Model-Based Design.
When your agent uses it
- Updating requirement artifacts from a model
Example prompts
- “Use the generate-requirement-drafts skill to generate draft requirements from Simulink models. An agent skill from matlab/simulink-agentic-toolkit”
- “/generate-requirement-drafts”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Understand the model — use the model_overview and model_read tools to understand subsystems, interfaces, control logic.
- Extract parameters — use the model_query_params / model_resolve_params tools for thresholds, gains, sample times that should appear in…
- Build a capture table (backend-neutral)
- Run the backend path (A or B below).
- Review using the gate below.
What it can do on your machine
Read from SKILL.md and the folder at commit c58e6ae. 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
Generate Requirement Drafts loads about 2.8k tokens when it runs, and up to ~4.6k if it reads all its reference files. Until then it costs about 58 tokens; SKILL.md has 1,175 words of instructions outside code blocks.
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 1,175 words (~2,825 tokens).
“Generate draft requirements from Simulink models using the richest artifact the environment supports. All outputs are drafts requiring human review and approval before baselining.”
