What it does
Simulink Explain Missing Coverage is an agent skill from matlab/simulink-agentic-toolkit. Use this skill when the user asks to summarize, or asks why Simulink Coverage objectives are missing, unsatisfied, or uncovered on a coverage result they already have — why specific decision, condition, MCDC, relational-boundary, or saturation/overflow outcomes weren't exercised, whether uncovered logic is dead code, or how to close the gap (a test, a coverage filter, or a design change). It reads an existing cvdata, .cvt file, sim-with-coverage output, or Simulink Test result; it never runs cvsim to collect…
Its SKILL.md is about 3.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including scripts and reference files (for example `manifest.yaml`, `references/coverage-filter-api.md` and `references/dead-logic-analysis.md`).
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
- The user asks to summarize
- Asks why Simulink Coverage objectives are missing
- Uncovered on a coverage result they already have — why specific decision
- Relational-boundary
Example prompts
- “/simulink-explain-missing-coverage”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Summarize coverage
- Locate missing objectives
- Explain and resolve
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 5 files in scripts/, which the agent can run.
Shell commands in SKILL.md call:
kind
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 Explain Missing Coverage loads about 3.2k tokens when it runs, and up to ~10k if it reads all its reference files. Until then it costs about 139 tokens; SKILL.md has 1,444 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 1,444 words (~3,185 tokens).
“Explain why coverage objectives are missing on a coverage result the user already has, and what to do about each one — across all objective types (decision, condition, MCDC, relational boundary, saturation/overflow, lookup-table execution). Works from an existing cvdata /…”

Can I use Simulink Explain Missing Coverage 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 simulink-explain-missing-coverage -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/simulink-explain-missing-coverage, .gemini/skills/simulink-explain-missing-coverage, .github/skills/simulink-explain-missing-coverage and .opencode/skills/simulink-explain-missing-coverage in your project.
What does Simulink Explain Missing Coverage need to run?
Going by SKILL.md and its folder, Simulink Explain Missing Coverage needs the command-line tools its instructions call (kind).
Does Simulink Explain Missing Coverage 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 Simulink Explain Missing Coverage 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 Simulink Explain Missing Coverage use?
