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. --- # nuqs Codemod Runner
Migrate a codebase from pre-v2.5 nuqs patterns to current v2.5–v2.8 idioms. The skill is **read-only by default** — it never modifies files without an explicit confirmation step, and refuses to run on a dirty git working tree.
## When to Apply
Trigger this skill when: - A user asks to "upgrade nuqs" or "migrate to nuqs 2.x" in a project that already uses nuqs - You spot any of the 5 legacy patterns during a review (see the codemod table below) - A `nuqs` version bump in `package.json` from `<2.5` to `>=2.5` is part of the diff - The user has just installed/updated the [`nuqs` skill](../nuqs/SKILL.md) and wants to bring existing code into line with it
This skill is the **automation companion** to `skills/.curated/nuqs/` — that skill teaches what each correct pattern looks like; this skill rewrites legacy code to match.
## Workflow Overview
``` ┌──────────┐ ┌────────────┐ ┌──────────────────┐ ┌───────────┐ ┌────────────┐ │ scan.sh │──▶ │ scan.json │──▶ │ report.sh │──▶ │ apply.sh │──▶ │ verify.sh │ └──────────┘ └────────────┘ │ (dry-run table) │ │ (codemods)│ │ (tsc+lint) │ └──────────────────┘ └───────────┘ └────────────┘ │ ▲ │ ▼ │ ▼ user reviews ──────────── confirms on fail: revert ```
1. **`scripts/scan.sh <repo-root>`** — ripgreps every `.ts/.tsx/.js/.jsx` file for the 5 legacy patterns, emits `scan.json` with `{path, line, matchedPattern, snippet, suggestion}`. 2. **`scripts/report.sh`** — renders `scan.json` as a markdown table grouped by codemod, with file paths and before/after pairs. **Show this output to the user verbatim** and ask for explicit confirmation before continuing. 3. **`scripts/apply.sh [--filter <codemod-id>]`** — runs the jscodeshift transforms in `scripts/transforms/`. Refuses to run unless a fresh `scan.json` exists for the current `git HEAD` and the working tree is clean (`--allow-dirty` overrides). 4. **`scripts/verify.sh`** — runs `tsc --noEmit` and `npm run lint` (or the equivalent commands from `config.json`). If anything fails, `git restore` reverts every file the codemod touched.
Run all four sequentially. If the user only wants to scan, stop at step 2.
## The Five Codemods
| ID | Detects | Rewrites to | |----|---------|-------------| | `throttle-ms` | `withOptions({ throttleMs: N })` or `setX(v, { throttleMs: N })` | `withOptions({ limitUrlUpdates: throttle(N) })` + adds `throttle` to the `nuqs` import | | `manual-debounce` | `useState` mirror + `useEffect` + `setTimeout` debounce around a `useQueryState` setter | `withOptions({ limitUrlUpdates: debounce(N) })` + adds `debounce` to the `nuqs` import; deletes the mirror state and effect | | `unchecked-json-cast` | `parseAsJson<T>()` (no validator) or `parseAsJson((v) => v as T)` | Inserts a `// TODO: validate` type-guard stub or, if Zod is detected in `package.json`, a `parseAsJson(SchemaName.parse)` form | | `react-router-unversioned` | `from 'nuqs/adapters/react-router'` | `from 'nuqs/adapters/react-router/v6'` (the alias the unversioned import historically pointed at) | | `parser-builder-type` | type references to `ParserBuilder<T>` from `nuqs` | `SingleParserBuilder<T>` |
See [`references/workflow.md`](references/workflow.md) for the exact AST shapes each codemod matches and the edge cases it deliberately skips.
## Setup
On first run, `config.json` is populated with the user's lint/typecheck commands and a default `min_node_version`. See `_setup_instructions` in `config.json` for what to fill in.
## Risk & Guardrails
This skill is **write-risk** (it modifies source files). Guardrails:
- `apply.sh` aborts if the working tree is dirty (use `git stash` first, or pass `--allow-dirty` after reading [`gotchas.md`](gotchas.md)) - `apply.sh` aborts if `scan.json` is older than 60 minutes or was generated against a different `git HEAD` — re-run `scan.sh` - The `hooks/hooks.json` PreToolUse matcher blocks any direct `node scripts/transforms/*.js` invocation that bypasses the orchestrator - `verify.sh` auto-reverts on TS or lint failure via `git restore` over the touched files (recorded in `last-run.json`)
