-**At most 300 words, in at most three paragraphs. Often far fewer.**

-to reach a length. If everything worth saying fits in forty words, say it in forty and stop.
-
-The ceiling exists because the first version of this prompt asked for "two to five paragraphs" and
-produced 932 words that read as a catalogue; the reader it was written for said it should have been
-three times shorter. Length is not thoroughness. A window of a hundred pull requests still gets 300
-words, because at that size the job is selection rather than coverage.
-
-**Never enumerate.** The one thing that bloats these reports is listing pull requests in prose --
-"an R-module of morphisms (TauCeti#90), preadditivity (TauCeti#106), a zero object (TauCeti#117),
-..." -- which is a changelog with paragraph breaks. Name the shape of the work and cite two or three
-pull requests as examples instead: "the comodule category acquired what a working category needs --
-preadditivity, a zero object, binary products, quotients (TauCeti#106, TauCeti#240, TauCeti#785)".
-The declarations are in the pull requests for anyone who wants them; this report says what they
-amount to.

-Aim for the register of a good "this month in mathlib" post: specific, unhurried, no marketing. A
-reader should be able to finish it.

-- Lead with the named results. If a recognised theorem landed, name it in the first sentence or two
-  and say in one clause what it states.
-- Cite pull requests inline as `TauCeti#1234`, right after what they delivered. Never a markdown
-  link, never a bare URL.
-- **Link named results to their documentation.** Every declaration in `__FACTS_FILE__` that has a
-  published page carries its URL in angle brackets at the end of its entry. When you name a theorem
-  or definition a reader might want to look up, link it with that URL copied exactly. Never build a
-  URL yourself: they are computed from the module path and the fully-qualified name and checked
-  against the published documentation, so one you assemble will look plausible and resolve to
-  nothing. An entry with no URL is private or was renamed away later in the window; name it in prose
-  and leave it unlinked. At most three links in the whole report. Keep the `TauCeti#1234`
-  citations as well: the pull request says where the work happened, the documentation link says what
-  the result is.
-- Group by mathematical content, not by pull request. Several pull requests that together built one
-  theorem are one story.
-- Be honest about proportion. Much of any window is infrastructure and consolidation; say so in a
-  sentence rather than inflating routine lemmas into results.
-- Say what is *not* there. If a headline result landed only in a special case, or with an extra
-  hypothesis, or as a shim awaiting an upstream Mathlib version, say which.

+- Group by mathematics, not by pull request. Several pull requests that built one theorem are one
+  story.
+- Most pull requests in a window aren't headline results. They add supporting lemmas, extend an API,
+  or move code around. Say in a few words what that work was about, then move on. Don't count it.
