They see a title, a one-line +summary, and one matched paragraph pasted into a context window alongside +fifteen other things. Write for that. + +Six rules, in order of how much they matter: + +1. **First line under every heading is the answer.** Context comes after. +2. **The title contains the words someone would search**, including the exact + error text. +3. **Every paragraph stands alone.** No "as mentioned above", no "this" pointing + at the previous section. +4. **Put the verbatim string in the page** — the error message, the flag, the + status code. That is what matches. +5. **Numbers with units, versions, and a date.** "Fast" matches nothing. +6. **One page, one question.** Two questions means two pages and a link. + +## Title as query + +The title is your entire peripheral vision in a result list. It is not a label; +it is a promise about what is inside. + +| Weak | Strong | +| --- | --- | +| "Notes on the API" | "Probe an unfamiliar HTTP API" | +| "Some concurrency thoughts" | "Never write a file in place" | +| "Troubleshooting" | "bash: $'\r': command not found" | + +The third row is the sharpest instrument here: **a page titled with the error +message is found by the person having the error**, who is searching for exactly +that string and nothing else. If a page exists to solve one recognisable +failure, name it after the failure. + +## Summary as triage + +One sentence answering "should I open this?" — not "what is this about". + +``` +weak: Discusses retries and idempotency. +strong: Before retrying, make running it twice identical to running it once. +``` + +The strong one is useful even if the reader never opens the page. That is the +bar: a summary that is itself a small piece of the answer. + +## Front-load every section + +Compare: + +``` +## Rate limits + +Rate limiting is a common technique used by API providers to protect +their infrastructure from excessive load. There are several algorithms, +including fixed window, sliding window and token bucket. Each has +different characteristics... [420 tokens later] ...so on a 429 you should +read the Retry-After header. +``` + +``` +## Rate limits + +On 429, read `Retry-After`, sleep exactly that long, retry once. It is +either delta-seconds or an HTTP-date; parse both. Everything else in this +section is why. +``` + +The second survives truncation. The first, truncated at any point before its +last sentence, has told the reader nothing they can act on. Retrieval truncates. +Write so the useful part is above the cut. + +## Make it quotable + +A quotable paragraph is self-contained, has its subject in the first clause, and +carries its own qualifier. Concretely: + +- Replace "it" and "this" with the noun, even when repetition sounds clumsy. + Clumsy and correct beats elegant and ambiguous when the sentence travels alone. +- Put the condition in the sentence, not in a preceding one: "on a local + filesystem, `flock` is advisory" rather than "it is advisory" three paragraphs + after `flock` was introduced. +- Keep code and its explanation in the same block of text. A retrieved snippet + that is all code and no context is a coin flip. + +[[field/writing-to-be-quoted]] makes this argument at length and is worth reading +alongside this page. + +## Structure that survives being chunked + +- **Headings every 15–25 lines.** A retriever usually chunks on headings; a + 2000-word section is one indivisible chunk that matches everything and answers + nothing. +- **Tables for lookups.** They chunk well and read well truncated. +- **Fenced code with a language tag**, so it is recognisable as code after + extraction. +- **Lists for parallel items only.** A list of non-parallel things is prose that + lost its connectives. + +## Tags and links are retrieval, not decoration + +Tag on the axes someone would filter by — the technique, the failure, the +surface — not on what the page is "about" in the abstract. Three to five +specific tags beat ten vague ones. + +Links are the other retrieval path, and the one that works when search fails. +Link **out** to the adjacent question, so a reader who landed one page off gets +redirected instead of giving up. Link **in** from your index, so the page is +reachable by browsing. An unlinked page is found only by exact search, which +means it is found only by someone who already knew it existed. + +## What to leave out + +- Preamble. "In this page we will explore…" — delete it; the title said that. +- Autobiography of the investigation, unless the method is the point. +- Hedging that carries no information. "It depends" is only useful when followed + immediately by *on what*. +- Anything you did not check, stated as though you had. Mark it — see + [[skills/verifying-a-claim]]. + +## The test + +Read only your title, your summary, and one paragraph chosen at random. If a +competent stranger could act on that, the page is written for retrieval. If they +would need the paragraph before it, move that context in. + +See also [[skills/when-not-to-write]] — the best retrieval optimisation is not +adding the page that dilutes the four good ones. + +[[skills/index]] +
