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 | $0.00000 | $0.00507 |
| Opus 5 | $0.00000 | $0.00253 |
| Sonnet 5 | $0.00000 | $0.00101 |
| Haiku 4.5 | $0.00000 | $0.00051 |
Grade A, and why
vercel 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 9d 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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vercel Skill
You are deploying to Vercel. Apply these conventions.
Deployment
- Connect the GitHub repo to Vercel — every push to
maindeploys to production; every PR creates a preview deployment. - Use
vercel.jsononly for rewrites, redirects, headers, and cron jobs — avoid overriding build settings that Vercel auto-detects. - Set environment variables in the Vercel dashboard per environment (Production / Preview / Development); use Vercel CLI (
vercel env pull) to sync to.env.local.
Edge vs Serverless Functions
- Choose the runtime per route with
export const runtime = 'edge'or'nodejs'. - Edge runtime: ultra-low latency, globally distributed, but limited Node.js APIs (no
fs, limitedcrypto). - Node.js runtime: full Node.js APIs, longer cold start — use for DB connections, file I/O.
- Connect to databases from the Edge with connection-pooled drivers (
@neondatabase/serverless, Supabase edge client).
Environment Variables
- Access env vars with
process.env.VAR_NAME— Vercel injects them at build time (public vars) and at runtime (secret vars). - Use
NEXT_PUBLIC_prefix for client-side accessible variables in Next.js. - Never commit
.envfiles; use.env.localfor local development (gitignored).
Image Optimization
- Vercel's Image Optimization runs
next/imageoptimizations automatically — setdomainsorremotePatternsinnext.config.tsfor external image hosts. - Cache optimized images at the CDN edge by setting an aggressive
Cache-Controlheader on image routes.
Cron Jobs
// vercel.json
{
"crons": [{ "path": "/api/cron/cleanup", "schedule": "0 2 * * *" }]
}
- Protect cron routes by verifying
Authorization: Bearer ${CRON_SECRET}header.
Performance
- Use Vercel's Analytics (
@vercel/analytics) and Speed Insights (@vercel/speed-insights) for Core Web Vitals monitoring. - Enable ISR (Incremental Static Regeneration) on Next.js pages with
revalidateto cache at the CDN. - Use Vercel KV (Redis), Vercel Postgres, or Vercel Blob for serverless-compatible storage.
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.

vercel is a skill published in the GitHub repository andresquirogadev/skillsense (2 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 507 tokens. 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.

ralphctl-code-review-and-quality
Multi-phase code-quality skill — primary frame for the evaluator role in Execute, the architecture axis in Plan, and correctness/readability in Refine. Multi-axis code review with severity vocabulary. Use when you are the evaluator assessing a generator's output, and when reviewing any change before signalling…
ralphctl-test-driven-development
Execute-phase skill — write the failing test before the code that makes it pass; for bug fixes, this is the reproduction test itself. Use for any logic change, bug fix, or behavioural modification; for the full root-cause triage pipeline around an unexpected failure, see ralphctl-debugging-and-error-recovery.
ralphctl-idea-refinement
Ideation skill — refine a raw, unshaped idea into a sharp, buildable concept through divergent expansion (variation lenses like inversion, simplification, audience shift) followed by convergent stress-testing (user value, feasibility, differentiation), ending in a one-pager with explicit assumptions and a "Not Doing"…
