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 | $0.02009 |
| Opus 5.5 | $0.00030 | $0.00804 |
| Sonnet 5.5 | $0.00015 | $0.00402 |
| Haiku 4.5 | $0.00007 | $0.00201 |
Grade A, and why
us-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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
US Business English
Professional and direct. Confident without being pushy. Friendly without being sloppy. Write like a competent American professional who gets things done -- not like a Silicon Valley bro, not like a Wall Street memo, and not like a corporate buzzword machine.
Spelling (EN-US)
| Pattern | American | Not |
|---|---|---|
| -or | color, favor, honor, behavior | colour, favour |
| -ize | organize, realize, specialize, recognize | organise, realise |
| -er | center, fiber, meter, theater | centre, fibre |
| -ense | license (noun and verb), defense, offense | licence (noun), defence |
| Single L | traveling, canceling, modeling | travelling, cancelling |
| -og | catalog, dialog, analog | catalogue, dialogue |
| -ment | judgment, acknowledgment | judgement, acknowledgement |
Noun/verb note: Unlike British/Australian English, American English uses "license" and "practice" for both noun and verb forms. No split needed.
Common traps: inquiry (standard, not enquiry), curb (road edge), tire (wheel), program (all contexts), check (not cheque), gray (not grey).
Date format: Month Day, Year -- January 15, 2026. Use this in all written communications unless matching a specific system format.
Tone Ladder
Match formality to context. Default to "professional friendly" -- clear and personable.
| Context | Formality | Greeting | Sign-off |
|---|---|---|---|
| Slack/Teams (internal) | Casual | "Hey" / first name | None needed |
| Email to existing client | Professional friendly | "Hi [Name]" | "Best" / "Thanks" |
| Email to new client | Professional | "Hi [Name]" | "Best" / "Thanks" |
| Proposal or quote | Professional | "Hi [Name]" | "Best regards" / "Best" |
| Follow-up after meeting | Professional friendly | "Hi [Name]" | "Thanks" / "Talk soon" |
| Cold outreach | Warm professional | "Hi [Name]" | "Best" / "Thanks" |
| Formal letter or legal | Formal | "Dear [Name]" | "Sincerely" |
Never use: "Dear Sir/Madam" (unless truly unknown recipient in legal context), "Warmest regards", "Respectfully yours" (reserve for military/government), "Cheers" (reads as affected British).
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.
