Nuqs Codemod Runner

What it does

When your agent uses it

• Even if the user only mentions upgrade nuqs
• Migrate to nuqs v2.5+ without naming the specific patterns — they almost always exist in pre-v2.5 codebases

Example prompts

• “s lint as a gate. Trigger even if the user only mentions”
• “migrate to nuqs v2.5+”
• “Use the nuqs-codemod-runner skill to migrate a nuqs codebase off pre-v2.5 patterns — deprecated throttleMs, hand-rolled setTimeout/useState debounce…”
• “/nuqs-codemod-runner”

Requirements

• Node.js
• A Bash shell

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

1. 1scripts/scan.sh — ripgreps every .ts/.tsx/.js/.jsx file for the 5 legacy patterns, emits scan.json with {path, line, matchedPattern…
2. 2scripts/report.sh — renders scan.json as a markdown table grouped by codemod, with file paths and before/after pairs. Show this output to…
3. 3scripts/apply.sh [--filter ] — runs the jscodeshift transforms in scripts/transforms/. Refuses to run unless a fresh scan.json exists for…
4. 4scripts/verify.sh — runs tsc --noEmit and npm run lint (or the equivalent commands from config.json). If anything fails, git restore…

What it can do on your machine

Read from SKILL.md and the folder at commit cf93c57. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Ships 10 files in scripts/ (Shell and JavaScript), which the agent can run.

  Shell commands in SKILL.md call:

  • git
  • tsc
  • npm
  • node

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use git and npm, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Nuqs Codemod Runner loads about 1.3k tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 147 tokens; SKILL.md has 505 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~147

When it runs · the whole SKILL.md, loaded when a task matches

~1.3k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~2.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description

Migrates a nuqs codebase off pre-v2.5 patterns — deprecated `throttleMs`, hand-rolled setTimeout/useState debounce around `useQueryState`, unchecked `parseAsJson` casts, unversioned `nuqs/adapters/react-router` imports, or `ParserBuilder<T>` type references. Scans the repo, produces a dry-run report, asks for confirmation, applies AST codemods, then runs `tsc --noEmit` + the user's lint as a gate. Trigger even if the user only mentions "upgrade nuqs" or "migrate to nuqs v2.5+" without naming the specific patterns — they almost always exist in pre-v2.5 codebases.
