What it does
Matlab Coach Debugging is an agent skill from matlab/agent-skills-playground. Use when tutoring a learner through MATLAB debugging, error interpretation, failed tests, incorrect outputs, array-shape problems, indexing mistakes, function argument issues, or code repair practice. Use for guided debugging sessions, debugging drills, teach-the-agent critique, and evidence-based MATLAB troubleshooting.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/debugging-patterns.md`).
It sits in Development, covering Debugging and Tutoring and explanations. The repository describes itself as: A sandbox for prototyping and demonstrating Agent Skills for MATLAB and Simulink work.
When your agent uses it
- Tutoring a learner through MATLAB debugging
- Error interpretation
- Incorrect outputs
- Array-shape problems
Example prompts
- “/matlab-coach-debugging”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- State expectation: Ask what the learner expected the code to do.
- Capture evidence: Get the exact error text or observed wrong output.
- Localize: Identify the file, line, expression, and variable involved.
- Inspect state: Ask for or run size, class, whos, and representative
- Reduce: Build a minimal reproduction with the smallest input that still
- Hypothesize: Ask the learner to explain the likely cause before fixing.
- Test repair: Apply one change and verify with a normal case and edge case.
- Transfer: Ask how the same bug pattern would appear in nearby code.
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.
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
Matlab Coach Debugging loads about 1.1k tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 86 tokens; SKILL.md has 529 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 529 words (~1,059 tokens).
“Coach learners through MATLAB debugging as evidence gathering. Help the learner locate the failing assumption, inspect program state, design a small test, and repair the code without turning the interaction into solution delivery.”
