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 | $0.00039 | $0.02023 |
| Opus 5.5 | $0.00016 | $0.00809 |
| Sonnet 5.5 | $0.00008 | $0.00405 |
| Haiku 4.5 | $0.00004 | $0.00202 |
Grade A, and why
configure-cache-busting 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 — 202 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to Use This Skill
| Use this skill when... | Use another approach when... |
|---|---|
| Configuring content hashing for Next.js or Vite builds | Optimizing server-side caching (nginx, CDN config directly) |
| Setting up CDN cache headers for Vercel or Cloudflare | Debugging build output issues (system-debugging agent) |
| Verifying cache-busting compliance after a framework upgrade | Configuring general CI/CD workflows (/configure:workflows) |
| Adding build verification scripts for hashed assets | Setting up container builds (/configure:container) |
| Auditing static asset caching strategy across a project | Profiling frontend performance (browser devtools) |
Context
- Project root: !
pwd - Package files: !
find . -maxdepth 1 -name 'package.json' - Next.js config: !
find . -maxdepth 1 -name 'next.config.*' - Vite config: !
find . -maxdepth 1 -name 'vite.config.*' - Build output: !

Parameters
Parse from command arguments:
--check-only: Report compliance status without modifications (CI/CD mode)--fix: Apply fixes automatically without prompting--framework <nextjs|vite>: Override framework detection--cdn <cloudflare|vercel|none>: Specify CDN provider for cache header configuration
Execution
Execute this cache-busting configuration check:
Step 1: Detect project framework
Identify the framework from file structure:
| Indicator | Framework | Config File |
|---|---|---|
next.config.js or next.config.mjs |
Next.js | next.config.* |
next.config.ts |
Next.js | next.config.ts |
vite.config.js or vite.config.ts |
Vite | vite.config.* |
.next/ directory |
Next.js (built) | Detection only |
dist/ directory + vite in package.json |
Vite (built) | Detection only |
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.

configure-cache-busting is a skill published in the GitHub repository laurigates/claude-plugins (60 stars, last pushed yesterday), licensed MIT. It adds 39 tokens to every session and 2,023 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
