Write an editorial brief a freelance writer who's never written for you can actually follow unsupervised

You are writing an editorial brief for a freelance writer who has never written for us before and will not have access to ask us clarifying questions before the first draft is due — the brief has to be self-contained enough that gaps in it become gaps in the draft, not something a phone call would have caught.

POST TOPIC AND GOAL
A post explaining our new usage-based pricing change, aimed at existing customers who might worry their bill is about to increase.

BRAND VOICE (WITH A REFERENCE EXAMPLE)
Our 'Why we killed seat-based pricing' post — short paragraphs, opens each section with a concrete customer scenario before explaining the reasoning, avoids exclamation points entirely.

REQUIRED STRUCTURE
1) What's changing (plain terms), 2) Why we made this change, 3) How to check if your bill changes, 4) What to do if you have questions.

SOURCES THE WRITER SHOULD USE
Our public pricing page and the internal pricing FAQ doc I'm attaching — no third-party pricing comparison sites, since our numbers there are already out of date.

DEADLINE AND WORD COUNT
First draft due in 5 days, 900-1,100 words.

Write the brief so a writer who knows nothing about us going in could produce a publishable-quality draft from it alone. State the voice as a comparison to the reference example rather than adjectives — describe specifically what the reference does (sentence length pattern, how it opens paragraphs, where it uses examples versus abstraction) so the writer has something concrete to match rather than a mood to guess at. State the required structure as a list of sections with a one-line purpose each, in the order they should appear, not just a suggested word-count split. List the approved sources explicitly and instruct the writer to flag, rather than silently substitute, any claim they can't support from those sources — a freelance writer without our context will otherwise reach for whatever ranks well in a quick search, which may contradict facts we already know are wrong or outdated.

WHAT NOT TO DO (INCLUDE THIS AS ITS OWN SECTION IN THE BRIEF)
Spell out common freelance-brief mistakes to specifically avoid for this piece: don't let the brief describe the topic so broadly that the writer could reasonably interpret it three different ways; don't leave the SEO keyword implicit inside a sentence when it should be a labeled field; don't assume the writer knows internal terms, product names, or acronyms we use casually — define every one that appears in the brief itself. If the brief as I've described it to you still leaves an ambiguity a first-time writer could plausibly misread, surface that ambiguity explicitly and resolve it rather than passing it through unaddressed.

OUTPUT FORMAT
1. The full brief, formatted with labeled sections: Topic & Angle, Audience, Voice (with the comparison points), Structure, Sources & Fact-Checking Rules, Do Not section, Deadline & Word Count.
2. A short separate note listing any ambiguity you caught and resolved that wasn't fully specified in what I gave you.
