Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00037 | $0.00570 |
| Opus 5 | $0.00018 | $0.00285 |
| Sonnet 5 | $0.00007 | $0.00114 |
| Haiku 4.5 | $0.00004 | $0.00057 |
Grade A, and why
gov-uk-style 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 12d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GOV.UK Style
Make complex information instantly clear, scannable, and accessible to every citizen.
The core rule
Start with the user's need. Sentences under 25 words, paragraphs under 5 lines, active voice, zero jargon.
Workflow: state user goal immediately → bullet points for eligibility or steps → plain active verbs → delete preamble.
Mechanics
- User need first. Every page starts with what the user can do or find.
- Short sentences. Maximum 25 words; vary length for rhythm.
- Active voice. "You must apply online" not "Applications must be submitted".
- No jargon. Replace bureaucratic terms with plain English (e.g. "pay" instead of "remuneration").
- Bulleted lists for steps. Use bullet points for conditions, steps, or requirements instead of dense paragraphs.
- Bold sparingly. Use bold only for critical warnings or key criteria.
- No Latin or Latinisms. Use "for example" instead of "e.g." and "that is" instead of "i.e.".
- Anchor links. Clear, descriptive link text that explains where the link goes.
Verify
- First sentence directly addresses the user's primary intent
- Sentences average under 20 words
- Bullet points used for lists of 3 or more items
- Zero Latin abbreviations (e.g., i.e., et al.)
- Active voice used throughout
Do not
- Use introductory throat-clearing ("It is important to note that...")
- Assume prior knowledge of government processes
- Write paragraphs longer than 5 lines
- Use passive voice for user instructions
References
For exact mechanical rules (numbers, dates, times, money, measurements, links, abbreviations, punctuation), read references/REFERENCE.md when a draft includes any of these — load on demand, not upfront.
Example transformations
Before: "In the event that an individual wishes to make an application for financial assistance, it is required that they submit documentation demonstrating eligibility prior to the commencement of the review process."
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

gov-uk-style is a skill published in the GitHub repository surendranb/writing-skills (33 stars, last pushed 9d ago), licensed MIT. It adds 37 tokens to every session and 570 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
