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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00019 | $0.00627 |
| Opus 5.5 | $0.00008 | $0.00251 |
| Sonnet 5.5 | $0.00004 | $0.00125 |
| Haiku 4.5 | $0.00002 | $0.00063 |
Grade A, and why
next-upgrade 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Upgrade Next.js
Upgrade the current project to the latest Next.js version following official migration guides.
Instructions
-
Detect current version: Read
package.jsonto identify the current Next.js version and related dependencies (React, React DOM, etc.) -
Fetch the latest upgrade guide: Use WebFetch to get the official upgrade documentation:
- Codemods: https://nextjs.org/docs/app/guides/upgrading/codemods
- Version-specific guides (adjust version as needed):
-
Determine upgrade path: Based on current version, identify which migration steps apply. For major version jumps, upgrade incrementally (e.g., 13 → 14 → 15 → 16).
-
Prefer the automated path first: the official upgrade codemod bumps deps AND runs the right transforms interactively:
npx @next/codemod@latest upgrade latest # or: upgrade patch|minor|major|<version> next upgrade # built-in self-upgrade command (Next 16.1+)Fall back to individual codemods when the automated path can't run:
npx @next/codemod@latest <transform> <path>Common transforms:
next-async-request-api- Updates async Request APIs (v15)next-request-geo-ip- Migrates geo/ip properties (v15)next-dynamic-access-named-export- Transforms dynamic imports (v15)remove-experimental-ppr/remove-unstable-prefix- PPR & unstable_* cleanup (v16)middleware-to-proxy- middleware.ts → proxy.ts (v16)next-lint-to-eslint-cli- migrate offnext lint(v16)
-
Update dependencies: Upgrade Next.js and peer dependencies together:
npm install next@latest react@latest react-dom@latest -
Review breaking changes: Check the upgrade guide for manual changes needed:
- API changes (e.g., async params in v15)
- Configuration changes in
next.config.js - Deprecated features being removed
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.

next-upgrade is a skill published in the GitHub repository georgekhananaev/claude-skills-vault (30 stars, last pushed 2mo ago), licensed MIT. It adds 19 tokens to every session and 627 once invoked, about $0.0001 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.
