- All requirements-related work in a MATLAB MBSE project using the Requirements Toolbox (slreq)
- SKILL.md covers The Two File Types, Two-Level Structure, Well-Formed Shall-Statements and Creating Requirement Sets, plus 16 more sections

What it does
Simulink Requirements is an agent skill from matlab/agent-skills-playground. Use this skill for all requirements-related work in a MATLAB MBSE project using the Requirements Toolbox (slreq). Covers creating and populating requirement sets, derivation links, test case requirements, verification coverage, reading and tracing links across requirement sets and models, checking link health, allocating requirements to components (Implement links), and building traceability reports. Trigger when the user asks about slreq API, slreqx files, slmx link files, outLinks/inLinks, traceability…
Its SKILL.md is about 6.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including reference files (for example `references/api-quickref.md`).
It sits in Testing & QA, covering Test generation and Literature review. The repository describes itself as: A sandbox for prototyping and demonstrating Agent Skills for MATLAB and Simulink work.
When your agent uses it
- All requirements-related work in a MATLAB MBSE project using the Requirements Toolbox (slreq)
- The user asks about slreq API
- Slmx link files
- OutLinks/inLinks
Example prompts
- “/simulink-requirements”
What it can do on your machine
Read from SKILL.md and the folder at commit 7b14a77. 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 matlab).
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
Simulink Requirements loads about 6.3k tokens when it runs, and up to ~8.2k if it reads all its reference files. Until then it costs about 171 tokens; SKILL.md has 2,306 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 2,306 words (~6,301 tokens).
“This skill covers everything in the slreq API: creating and reading requirements, managing traceability links, checking verification coverage, allocating requirements to architecture components, and auditing link health.”
