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.

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 | $0.00048 | $0.00774 |
| Opus 5 | $0.00024 | $0.00387 |
| Sonnet 5 | $0.00010 | $0.00155 |
| Haiku 4.5 | $0.00005 | $0.00077 |
Grade A, and why
tw-migrate 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 6d 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.

Tailwind v3 to v4 Migration
When to Use
Use this skill when:
- Upgrading an existing Tailwind CSS v3 project to v4
- You encounter v3 patterns in a project that should be on v4
- A project has version mixing (some v3, some v4 patterns)
Instructions
-
Read the project's package.json to identify installed Tailwind version and related packages (
tailwindcss,autoprefixer,postcss-import,@tailwindcss/typography,@tailwindcss/forms,@tailwindcss/container-queries) -
Read the CSS entry point file (usually
src/index.css,src/app.css,src/globals.css, orstyles/globals.css) and check for@tailwinddirectives vs@import "tailwindcss" -
Check for
tailwind.config.jsortailwind.config.tsand read its contents. Note: theme customizations, plugins, content paths, and any advanced config (safelist, corePlugins, separator) -
Read
postcss.config.js,postcss.config.mjs, orpostcss.config.cjsif it exists -
Read
vite.config.ts,vite.config.js, or the equivalent build tool config -
Search template files (
.html,.jsx,.tsx,.vue,.svelte,.blade.php,.erb) for these v3 patterns:bg-opacity-,text-opacity-,border-opacity-,ring-opacity-,divide-opacity-,placeholder-opacity-shadow-sm(will need rename toshadow-xs)blur-sm(will need rename toblur-xs)rounded-sm(will need rename torounded-xs)outline-none(will need rename tooutline-hidden)overflow-ellipsis(will need rename totext-ellipsis)flex-grow,flex-shrink(will need rename togrow,shrink)transform(the transform class prefix, no longer needed)!at the beginning of utility classes (needs to move to end)[--for arbitrary CSS variable syntax (needs to become(--)
-
Check browser support requirements. v4 requires Safari 16.4+, Chrome 111+, Firefox 128+. If the project needs older browser support, warn that migration may not be appropriate.
-
Generate a migration report with:
- Dependency changes - exact npm commands to run
- Config changes - what to convert from JS to CSS
@theme, what@configbridge is needed - CSS changes - import syntax, custom utilities, custom variants
- Template changes - count of each v3 pattern found, with exact find-and-replace commands
- Build tool changes - PostCSS or Vite config updates
- Risk assessment - which changes are safe to automate vs need manual review
- Post-migration verification - what to visually check
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.

tw-migrate is a skill published in the GitHub repository RoninForge/roninforge-tailwind-v4 (2 stars, last pushed 2mo ago), licensed MIT. It adds 48 tokens to every session and 774 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 2026-08-31.
