What it does
Technical Book Lab Design is an agent skill from hashgraph-online/awesome-codex-plugins. Design hands-on technical nonfiction chapters as runnable labs, worked examples, exercises, checkpoints, troubleshooting paths, and reader outcomes. Use when turning technical book sections, tutorials, self-hosting chapters, DevOps guides, programming lessons, or infrastructure explanations into practical labs that readers can complete and verify.
Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `agents/openai.yaml`, `references/core/checklist.md` and `references/core/examples.md`). Compatibility notes: Codex, Claude Code, and other Agent Skills-compatible clients.
The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is MIT.
When your agent uses it
- Turning technical book sections
- Self-hosting chapters
- Programming lessons
- Infrastructure explanations into practical labs that readers can complete and verify
Example prompts
- “/technical-book-lab-design”
Requirements
- Compatibility (from SKILL.md): Codex, Claude Code, and other Agent Skills-compatible clients.
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 9e7b281. 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.
Compatibility
Codex, Claude Code, and other Agent Skills-compatible clients.
From compatibility in the SKILL.md frontmatter.
Context cost
Technical Book Lab Design loads about 855 tokens when it runs, and up to ~3.8k if it reads all its reference files. Until then it costs about 94 tokens; SKILL.md has 380 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.

Technical Book Lab Design
Core Lens
A technical book lab is not a pile of commands. It is a guided reader transformation with a clear starting state, safe path, visible progress, expected output, and exit criteria. The reader should know what they built, why it works, how to verify it, and what to do when it fails.
Use this skill to design or improve:
- Self-hosting chapters.
- DevOps, infrastructure, programming, data, or security tutorials.
- Worked examples and exercises.
- Lab prerequisites and environment assumptions.
- Checkpoints, expected outputs, and troubleshooting branches.
Reference Routing
| Need | Read |
|---|---|
| Core lab concepts and terminology | references/core/knowledge.md |
| Lab design rules | references/core/rules.md |
| Before/after examples | references/core/examples.md |
| Lab review checklist | references/core/checklist.md |
| Step-by-step lab design | workflows/design-runnable-lab.md |
Workflow
1. Name The Reader Outcome
State what the reader will be able to do, decide, deploy, debug, or explain after the lab.
If the outcome is only "learn about X," sharpen it until there is visible proof of progress.
2. Define The Starting State
List what the reader already has and knows:
- Required concepts.
- Accounts, hardware, software, versions, and operating system.
- Network, domain, DNS, permissions, credentials, or safety constraints.
- Files or repo state.
Move missing prerequisites earlier, compress them, or link them to companion material.
3. Design The Path
Structure the lab as small checkpoints:
- Explain the purpose before each action.
- Give the smallest safe command or change.
- Show expected output or state.
- Add a quick verification.
- Explain the next decision.
Show full SKILL.md (145 more words)Show less
4. Add Failure Handling
Technical readers do not only need the happy path.
- List likely errors and what they mean.
- Add rollback or cleanup steps where changes are risky.
- Mark steps that expose services, change permissions, spend money, or affect data.
- Tell readers when to stop and ask for help.
5. Close The Loop
End every lab with:
- Final verification.
- What the reader should understand now.
- What they can safely change next.
- Cleanup, maintenance, or security follow-up.
Output Format
When designing or reviewing a lab, return:
- Reader outcome and starting-state assumptions.
- Lab sequence with checkpoints.
- Expected outputs and verification steps.
- Troubleshooting table.
- Safety notes and cleanup.
- Suggested companion resources or prerequisites.
Quality Bar
Make the lab useful to a real reader in a real environment. Prefer concrete outputs, checkpoints, and failure handling over abstract explanation or untested command sequences.
