Tech Tutorial

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.

When To Use

• Writing a getting-started guide for a library, CLI tool, or API
• Creating a step-by-step walkthrough that readers follow at a terminal
• Explaining a technical concept through a hands-on exercise
• Producing a how-to that complements API reference documentation

When NOT To Use

• Generating API reference docs (use scribe:doc-generator)
• Cleaning up existing prose (use scribe:slop-detector)
• Producing high-level architecture overviews without runnable steps
• Writing conceptual essays without hands-on components

Methodology

Step 1: Scope and Audience

Before writing a single line, answer these questions:

• Who is this for? (experience level, assumed prior knowledge)
• How many readers? How often will each one read it?
• What will they build or accomplish by the end?
• What is the one sentence they must walk away with? (the thesis — not the topic)
• What is the single prerequisite the reader must have installed?
• What is explicitly out of scope?

Write 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.

Step 2: Outline

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.

Step 3: Draft Code Examples First

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.

Step 4: Draft Prose Around the Code

Prose exists to explain what the code does and why. Follow these rules:

• One paragraph per step: what to run, what it does, what to expect
• State the expected output after each command block
• Use second person ("you") consistently throughout
• Do not narrate what the reader will do next; just present the next step

Step 5: Build Complexity Gradually

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.

Step 6: Slop Check

After drafting, run:

Skill(scribe:slop-detector)

Fix all tier-1 findings before proceeding. Pay particular attention to:

• Tier-1 vocabulary slop (see scribe:slop-detector word lists)
• Tricolon adjective clusters ("fast, efficient, and reliable")
• Participial tail-loading (sentences ending with ", enabling ...")

Step 7: Quality Gate

Verify the completed tutorial against this checklist:

Content:

• All code blocks tested and produce the stated output
• Prerequisites section lists exact versions where relevant
• Every step states the expected result
• Troubleshooting section covers at least two common failure modes

Sentence-level:

• No tier-1 slop words
• Em dash count is under 2 per 1000 words
• Bullet ratio is under 40%
• Line length wraps at 80 characters

Document-level (document-economy module):

• Thesis from Step 1 appears in the lead paragraph
• Thesis echoed at the close (and ideally mid-tutorial)
• No "in summary" section that re-lists what just happened
• No section opens by restating its heading
