What it does
Code Instructor is an agent skill from aiskillstore/marketplace. Educational code development skill that teaches programming concepts while building applications. Use when the user wants to learn how code works, understand programming concepts, or build an app with detailed explanations. Provides line-by-line breakdowns, explains the 'why' behind code patterns, uses pedagogical teaching methods, and builds apps incrementally with educational commentary at each step.
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `references/common-mistakes.md`, `references/teaching-patterns.md` and `scripts/annotate_code.py`).
The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- The user wants to learn how code works
- Understand programming concepts
- Build an app with detailed explanations
Example prompts
- “/code-instructor”
Requirements
- Python 3
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- App Development Flow
- Code Explanation Framework
- Concept Introduction Pattern
- Debugging as Teaching
What it can do on your machine
Read from SKILL.md and the folder at commit ad8daf7. 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 1 file in scripts/ (Python), which the agent can run.
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
Code Instructor loads about 2.2k tokens when it runs, and up to ~5.3k if it reads all its reference files. Until then it costs about 105 tokens; SKILL.md has 1,031 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,031 words (~2,229 tokens).
“This skill enables Claude to teach programming concepts while simultaneously building functional applications. Every line of code is explained, every decision is justified, and learning happens through doing.”
