jezweb/claude-skills is a collection of skills, commands, plugins, settings, instructions, and hooks that guide the Claude Code CLI through development tasks and produce outputs such as project scaffolds, assets, documents, or deployed services. It is for developers using Claude Code with technologies and services including Cloudflare, React, Tailwind, Shopify, and WordPress. The catalogue entries are the project's own Claude Code workflow components.
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 | $0.00074 | $0.02121 |
| Opus 5.5 | $0.00030 | $0.00848 |
| Sonnet 5.5 | $0.00015 | $0.00424 |
| Haiku 4.5 | $0.00007 | $0.00212 |
Grade A, and why
uk-business-english 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 1mo 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 — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.
UK Business English
Professional and measured. Polite without being obsequious. Direct without being abrupt. Naturally British without being a caricature. Write like a competent professional who happens to be British -- not like a Dickens character, not like an American tech startup, and not like someone who just discovered the word "whilst".
Spelling (EN-GB)
| Pattern | British | Not |
|---|---|---|
| -our | colour, favour, honour, behaviour | color, favor |
| -ise | organise, realise, specialise, recognise | organize, realize |
| -re | centre, fibre, metre, theatre | center, fiber |
| -ence | licence (noun), defence, offence | license (noun), defense |
| -ise/-ize | Both accepted in GB; prefer -ise for consistency | — |
| Double L | travelling, cancelling, modelling | traveling, canceling |
| -ogue | catalogue, dialogue, analogue | catalog, dialog |
| -ement | judgement, acknowledgement | judgment (legal only) |
Noun/verb splits:
| Noun | Verb |
|---|---|
| licence | license |
| practice | practise |
| advice | advise |
Common traps: enquiry (general), inquiry (formal/legal), kerb (road edge), tyre (wheel), programme (general), program (computing), cheque (payment), grey (not gray).
Date format: Day Month Year, no comma -- 15 January 2026. Abbreviated: 15 Jan 2026. Never Month/Day/Year.
Tone Ladder
Match formality to context. Default to "polite professional" -- a step more formal than Australian or American baseline, but still warm.
| Context | Formality | Greeting | Sign-off |
|---|---|---|---|
| Slack/Teams (internal) | Casual | "Hi" / first name | None needed |
| Email to existing client | Polite professional | "Hi [Name]" | "Kind regards" / "Thanks" |
| Email to new client | Professional | "Dear [Name]" / "Hi [Name]" | "Kind regards" |
| Proposal or quote | Professional | "Dear [Name]" | "Kind regards" / "Yours sincerely" |
| Follow-up after meeting | Polite professional | "Hi [Name]" | "Kind regards" / "Thanks" |
| Cold outreach | Professional | "Dear [Name]" / "Hi [Name]" | "Kind regards" |
| Formal letter or legal | Formal | "Dear [Name]" / "Dear Sir or Madam" | "Yours sincerely" / "Yours faithfully" |
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.
