A writing guide for public-service content, based on GOV.UK content design. GOV.UK is the UK government's website for information and services.

Use it to draft, rewrite, or check eligibility pages, government guidance, policy explanations, forms, transactions, and public notices.

It helps people find the answer, make a decision, or complete a task without losing important legal conditions, dates, costs, or exceptions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00059	$0.00704
Opus 5.5	$0.00024	$0.00282
Sonnet 5.5	$0.00012	$0.00141
Haiku 4.5	$0.00006	$0.00070

Security

Grade A, and why

govuk scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GOV.UK

Write around the person's need, not the institution's structure or policy-making process.

Protect meaning

Preserve legal conditions, duties, dates, amounts, evidence requirements, and consequences exactly.
Do not simplify away an exception. Separate the main case from exceptions.
Do not infer eligibility or give personal legal advice from incomplete facts.
Flag conflicts between plain-language clarity and mandated wording.

Start with the user need

Write the question the person is trying to answer or the task they need to do.
Identify the decision they must make before reading further.
List the minimum facts needed for that decision: who qualifies, what it costs, what evidence is needed, how long it takes, and what happens next.
Order the page by user journey, not by department, legislation, or internal team.
Remove information that does not help the user decide, act, or understand a consequence. Link to specialist detail when it serves a smaller audience.

Write plainly

Put the answer or action near the beginning.
Use common, concrete words. Explain a necessary technical or legal term in the same sentence.
Address the reader as you. Name the responsible organization when it acts.
Use active voice and strong verbs. Replace abstract nouns with the action they hide when meaning stays intact.
Keep sentences focused. Split chains of conditions into bullets or separate cases.
Use examples only when they clarify a rule. Label them as examples, not as the rule itself.
State uncertainty, discretion, and possible outcomes honestly.

Structure the service content

Use front-loaded, sentence-case headings that match words people would search.
Place universal information first, then conditional routes and exceptions.
Use numbered steps only for a required sequence.
Put warnings immediately before the risky action, not in a general introduction.
Make link text describe the action or destination.
Give forms and fields labels that name the requested information, with hint text only when the label is not enough.
End with the next action, alternative route, or source of help.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
