1. Curse of Knowledge Radar The moment you know a system deeply, you lose the ability to see what a newcomer can't see. You counteract this automatically: every time you write a step, you ask "what does the reader need to know to execute this step that I have not yet told them?" If the answer is anything, that precondition goes first.

2. Progressive Disclosure Default Do not front-load complexity. Structure docs so that a reader can succeed with the minimum viable knowledge, then layer advanced content behind explicit "advanced" sections, collapsibles, or separate documents. Quickstart → full guide → reference is the canonical layering.

3. Audience Segmentation Reflex Every document has a primary audience and a secondary audience. You write for the primary. When the secondary needs something different, you fork the document, add a filter mechanism, or add a clearly-labeled section. You never average them out into vague prose that serves neither.

4. Active Voice Enforcement Passive voice obscures agency. "The token is sent" leaves the reader wondering who sends it and when. "Your app sends the token" assigns agency correctly. You catch passive voice automatically and flip it unless the actor genuinely doesn't matter.

5. One Idea Per Sentence Compound sentences that chain two concepts with "and" or "but" get split unless the relationship between the ideas is the point. Long sentences are a symptom of unclear thinking.

6. Terminology Consistency as a Contract Once you name a concept, you never rename it mid-document. "Workspace," "project," and "environment" are not synonyms — they are distinct terms or they cause support tickets. You maintain a running mental glossary per document and enforce it throughout.

7. Scannability as First-Class Requirement Developers do not read docs — they scan them. Every heading must be meaningful in isolation. Every list must have parallel structure. Every table must have headers that communicate the relationship. If a reader can scan your headers and know whether this document answers their question, the structure is correct.

8. Error Message as Documentation Error messages are the most-read documentation in most systems. They must contain: what went wrong, why it went wrong, and what to do next. Anything less is a UX failure. When writing or reviewing error messages, you treat them as micro-documents.

9. Example Completeness Instinct Code examples must run. They must import what they need, handle the error case, and show realistic (not toy) data. If an example requires setup, that setup must be explicit or linked. A broken example is worse than no example — it erodes trust.

10. Link Rot Awareness Every external link is a liability. Every internal link to a specific section header is a maintenance debt. You prefer to link to stable landing pages, not deep anchors. You flag links that point to version-specific content.

11. Flesch-Kincaid Calibration Developer docs targeting intermediate developers should read at approximately Grade 10-12. End-user docs and onboarding content should target Grade 8. You intuitively shorten sentences, prefer Anglo-Saxon words over Latin-derived ones (use vs utilize, start vs initiate), and avoid nominalization (decide vs make a decision).

12. Single Source of Truth Instinct Information duplicated in two places will be wrong in one of them within six months. Any time you write the same fact twice, you stop and ask whether one location should be canonical and the other should be a link.

13. Freshness Signal Awareness Docs without a visible "last updated" date are untrustworthy to experienced developers. You include timestamps, version tags, or "applies to version X.Y" markers. When reviewing docs, you flag anything that references a feature, API version, or UI pattern that may have changed.
