What it does
Resolve Design Errors is an agent skill from matlab/simulink-agentic-toolkit. Use when asked to run Design Error Detection (quick defect scan), find design errors in a Simulink model, perform root cause analysis on DED findings, fix division-by-zero, overflow, dead logic or out-of-bounds defects detected by SLDV, or diagnose why missing coverage cannot be achieved (dead logic blocking coverage objectives). Do NOT use for requirement verification, test generation, Inf/NaN detection, active logic analysis, or coverage measurement.
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 30 other files, including scripts, reference files and assets (for example `assets/design_error_assumption.yaml`, `assets/design_error_cascading.yaml` and `assets/design_error_conditionally_executed.yaml`).
It sits in Development, covering Root cause analysis and Test generation. 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
- Asked to run Design Error Detection (quick defect scan)
- Find design errors in a Simulink model
- Perform root cause analysis on DED findings
- Fix division-by-zero
Example prompts
- “/resolve-design-errors”
Workflow steps
2 steps, taken from the step headings in SKILL.md.
- Detect errors
- Root cause errors
What it can do on your machine
Read from SKILL.md and the folder at commit 455dded. 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 4 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
Resolve Design Errors loads about 2.1k tokens when it runs, and up to ~4.2k if it reads all its reference files. Until then it costs about 120 tokens; SKILL.md has 1,011 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); 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 1,011 words (~2,141 tokens).
“Requires: MATLAB R2023b+, Simulink Design Verifier, Simulink Check / Model Slicer.”

Resolve Design Errors fits situations like: asked to run Design Error Detection (quick defect scan); find design errors in a Simulink model; perform root cause analysis on DED findings; fix division-by-zero.
How do I install Resolve Design Errors in Claude Code?
Run `npx skills add matlab/simulink-agentic-toolkit --skill resolve-design-errors -a claude-code`. Or copy the skill folder (skills-catalog/verification-validation-and-test/resolve-design-errors in matlab/simulink-agentic-toolkit) into .claude/skills/resolve-design-errors in your project. Claude Code loads it when a task matches its description.
How do I install Resolve Design Errors in Codex?

Or copy the skill folder (skills-catalog/verification-validation-and-test/resolve-design-errors in matlab/simulink-agentic-toolkit) into .agents/skills/resolve-design-errors in your project. Codex loads it when a task matches its description.
Can I use Resolve Design Errors in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add matlab/simulink-agentic-toolkit --skill resolve-design-errors -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/resolve-design-errors, .gemini/skills/resolve-design-errors, .github/skills/resolve-design-errors and .opencode/skills/resolve-design-errors in your project.
What does Resolve Design Errors need to run?
SKILL.md names no scripts, command-line tools or credentials: Resolve Design Errors is instructions for the agent only.
Does Resolve Design Errors access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Resolve Design Errors safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Resolve Design Errors use?
Resolve Design Errors has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Resolve Design Errors use?
About 2.1k tokens (SKILL.md is roughly 8.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2k tokens, read only when the agent opens those files.
What are the alternatives to Resolve Design Errors?
Skills that share tags, products or a category with Resolve Design Errors: OpenROAD Bug Fixer (The-OpenROAD-Project/OpenROAD, 3.2k stars), Eval Triage And Improvement (microsoft/eval-guide, 138 stars), Generating Test Reports (foryourhealth111-pixel/Vibe-Skills, 3.6k stars) and Xpu CI Health Check (intel/torch-xpu-ops, 115 stars).
