Tech Tutorial is an agent skill from athola/claude-night-market. Plans, drafts, and refines technical tutorials for developers. Use when writing step-by-step guides or getting-started walkthroughs backed by working code.
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `modules/code-examples.md`, `modules/outline-structure.md` and `modules/progressive-complexity.md`).
It sits in Testing & QA. The repository describes itself as: 23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context… The licence is MIT.
7 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 9f3eb00. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Tech Tutorial loads about 1.8k tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 891 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.
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.

.claude/skills/tech-tutorial/SKILL.md (or your agent's skills folder). This skill also uses 3 other files; get the full folder from GitHub.A good technical tutorial has one goal: move a reader from not knowing how to do something to being able to do it. That requires working code, concrete steps, and honest acknowledgment of where things go wrong. This skill guides you through outlining, drafting, and verifying a tutorial that meets that standard.
scribe:doc-generator)scribe:slop-detector)Before writing a single line, answer these questions:
newcomer, practitioner,
expert, or a one-line persona. A tutorial defaults to
newcomer; if it does not, say what it assumes insteadWrite these answers down as a header block in the draft. If you cannot answer the "what will they accomplish" question in one sentence, the scope is too broad. If you cannot state the thesis in one sentence, the tutorial is not ready to draft.
The audience size and read frequency feed the reader-time
budget (see scribe:slop-detector module document-economy.md).
A tutorial that 500 developers will read once is a 40-hour
reader-budget asset. Spend the writing time accordingly.
The tier decides what the draft may contain. When the request
names no reader, ask, do not guess: scribe:slop-detector
module audience-targeting.md carries the tier table and the
Socratic set.
A newcomer tutorial keeps the one path that works, end to
end. Alternatives, internals, and the reasons the obvious
approach fails are expert material. They go to
docs/deep-dive/<topic>.md, linked from the lead in one line
that names who the deep dive is for. Never delete them to hit
the tier. A tutorial that pauses to compare three approaches
has stopped moving the reader from cannot to can.
Load: @modules/outline-structure.md
Produce a section-by-section outline before drafting prose. Each section entry must include a one-line description of what the reader does or learns in that section. See the outline module for the standard section order and length targets per section type.
Load: @modules/code-examples.md
Write the code before the prose. Each snippet must run against a real environment before it appears in the tutorial. Annotate only the non-obvious lines. See the code examples module for formatting and error-handling rules.
Prose exists to explain what the code does and why. Follow these rules:
Load: @modules/progressive-complexity.md
Start with the minimal working example. Introduce variations and edge cases only after the baseline works. See the progressive complexity module for the layering rules and pacing guidance.
After drafting, run:

Tech Tutorial fits situations like: writing step-by-step guides; getting-started walkthroughs backed by working code.
Run `npx skills add athola/claude-night-market --skill tech-tutorial -a claude-code`. Or copy the skill folder (plugins/scribe/skills/tech-tutorial in athola/claude-night-market) into .claude/skills/tech-tutorial in your project. Claude Code loads it when a task matches its description.
Run `npx skills add athola/claude-night-market --skill tech-tutorial -a codex`. Or copy the skill folder (plugins/scribe/skills/tech-tutorial in athola/claude-night-market) into .agents/skills/tech-tutorial in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add athola/claude-night-market --skill tech-tutorial -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/tech-tutorial, .gemini/skills/tech-tutorial, .github/skills/tech-tutorial and .opencode/skills/tech-tutorial in your project.
SKILL.md names no scripts, command-line tools or credentials: Tech Tutorial is instructions for the agent only.
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.
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. Review the folder before installing.
Tech Tutorial is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.8k tokens (SKILL.md is roughly 7.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
