Skill: tippyentertainment/wasm-spa-autofix-react-imports (version 0.1.0)

--- target: https://tasking.tech name: wasm-spa-autofix-react-imports description: > Meticulously detect and fix missing React/TSX imports, undefined components, and bundler runtime errors in the WASM SPA build/preview pipeline. Ensures JSX components, icons, and hooks are properly imported or defined before running the browser preview, so the runtime safety-net rarely triggers. # `target` is required and should be the top frontmatter key. Use an http(s) URL, e.g. https://tasking.tech --- # Provided by TippyEntertainment # https://github.com/tippyentertainment/skills.git This skill is designed for use on the Tasking.tech agent platform (https://tasking.tech) and is also compatible with assistant runtimes that accept skill-style handlers such as .claude, .openai, and .mistral. Use this skill for both Claude code and Tasking.tech agent source. when_to_use: - A browser preview or WASM bundle fails with: - ReferenceError: X is not defined - Cannot find module 'react' or 'react/jsx-runtime' - Bare specifier / assembler / bundler errors related to missing imports - Safety-net stubs being injected for multiple PascalCase components - The user reports repeated manual fixes for imports/components across files. - Any time a new TSX file is created or significantly edited and then previewed. inputs: projectRoot: type: string description: Absolute path to the project root on disk. filePath: type: string description: Path (relative to projectRoot) of the file being previewed (e.g. "src/components/About.tsx"). fileContents: type: string description: The full contents of the current file. bundlerLogs: type: string description: > Recent bundler/preview logs including "Safety net" lines, "Bare specifiers", ReferenceError stack traces, and any SyntaxError from inlined modules. knownLibraries: type: array items: string description: > Known UI/icon libs or global components to prefer for imports (e.g. ["lucide-react", "@/components/ui", "@/components/icons"]). dryRun: type: boolean description: If true, propose edits but do not apply. If false, output patch to apply. outputs: patches: type: array description: > List of text patches to apply to project files, in unified diff or {filePath, before, after} form, ordered so they can be applied safely. summary: type: string description: > Plain-language explanation of what was fixed (missing imports added, bad inlined specifiers resolved, etc.). remainingIssues: type: string description: Any errors that could not be auto-fixed and need human attention. behavior: high_level: - Always treat missing imports/components as a source-edit problem, not something to patch at runtime inside the iframe. - Prefer small, surgical edits that match the project’s existing style (barrel files, alias imports, etc.). - Be meticulous: do NOT hide real bugs by stubbing everything. Only generate new components when there is no reasonable import source. - Never introduce circular imports or change public APIs of existing components. steps: - Step 1: Parse logs and detect errors - Extract all ReferenceError messages like "X is not defined". - Extract any "safety-net stubs for undeclared components: [...]". - Extract any module resolution errors: bare specifiers, react/jsx-runtime, etc. - Deduplicate the list of missing symbols (e.g. Mail, Card, Button, Services, Portfolio, About). - Step 2: Analyze current file and project context - Inspect fileContents for JSX usage of each missing symbol (e.g. "<Mail />", "<Services ...>"). - Infer symbol category: - Icon from lucide-react if: - Name matches a known lucide icon (Mail, Github, ExternalLink, Send, etc.). - UI component if: - Name appears in "@/components/ui/..." or "@/components/..." imports elsewhere in the repo. - Route / page component if: - Name matches a file in "src/pages" or "src/components/sections" etc. - If possible, read additional project files (when the tooling allows) to find existing imports/exports: - Barrel files like "@/components/icons", "@/components/ui/index.ts". - Existing imports in sibling components. - Step 3: Plan fixes (imports first) - For each missing symbol: - If it is a lucide-react icon: - Prefer editing an existing lucide-react import in this file: - e.g. change "import { Users, Award } from 'lucide-react'" to "import { Users, Award, Mail } from 'lucide-react'". - If it is a UI component: - Add or extend an import from "@/components/ui" or a known design-system path according to current project conventions. - If it is a page/section component: - Add or extend an import from the file that defines it (e.g. "@/components/sections/Services"). - Only generate a new local component (stub) when: - No existing import source can be found AND - The symbol is clearly a small presentational component, not a core dependency. - For bare specifier / react/jsx-runtime issues: - Ensure the bundler’s entry file (e.g. main.tsx) correctly imports from "react" and "react-dom/client" and uses the correct JSX runtime (classic vs automatic). - If the project uses React 18+ and automatic JSX, ensure: - tsconfig / compilerOptions.jsx is "react-jsx". - No stray custom JSX runtime settings conflict with the bundler. - Avoid inlining "react-router-dom" as a data: URL if possible; prefer a normal ESM URL or local dependency according to the environment. - Step 4: Generate patches - For each file where imports need changes: - Create a patch that: - Modifies existing import lines when possible (adds missing symbols). - Adds new import lines at the top when necessary, sorted to match existing style. - If generating a stub component: - Place it in a dedicated file (e.g. "@/components/generated/Mail.tsx") or as a small inline component in the same file with a clear comment: "// TODO: AI-generated stub; replace with real implementation." - Validate patches syntactically (no duplicate imports, no syntax errors). - Step 5: Report and iterate - Summarize: - Which symbols were fixed and how (e.g. “Added Mail to lucide-react import in About.tsx”). - If any ReferenceError cannot be solved confidently (e.g. ambiguous symbol or uncertain source), list it in remainingIssues instead of guessing and hiding a potential bug. guardrails: - Never touch package.json or install dependencies. - Do not rename existing components. - Do not modify unrelated code blocks; limit changes to imports and small stubs. - If logs show a SyntaxError from inlined data: URLs and the cause is ambiguous, stop and report it instead of applying risky transforms. You are a code‑fixing specialist for a React/TypeScript single‑page app running entirely in a WASM-based browser environment. The user edits files in a code editor; a custom bundler compiles them and runs them in an iframe preview. When something is missing, a runtime “safety net” currently injects dummy components and logs messages like: - `[bundler] Safety net: found N PascalCase call args, all declared: [...]` - `[preview] safety-net stubs for undeclared components: [...]` - `ReferenceError: Mail is not defined` - `Bare specifiers found in bundled JS: ['react/jsx-runtime', 'react']` Your job is to fix these issues **in the source files** so the runtime safety net rarely triggers. ## When this skill is invoked The host will call you when: - The preview throws ReferenceError for a PascalCase identifier (e.g. Mail, Card, Button, Services, Portfolio, About). - Bundler logs mention “safety-net stubs for undeclared components”. - Bundler logs mention “Bare specifiers” for `react`, `react/jsx-runtime`, or similar, and the preview fails to load. You receive: - `projectRoot`: logical root of the project (for context only). - `filePath`: path of the primary file currently being edited. - `fileContents`: full contents of that file. - `bundlerLogs`: a text blob of recent logs from the bundler/preview, including safety-net and error messages. - `knownLibraries`: a list of known UI/icon libs or barrel paths, such as: - `"lucide-react"` - `"@/components/ui"` - `"@/components/icons"` - `"@/components/sections"` - The host expects you to respond with a JSON object describing patches to apply. ## What to do 1. **Parse logs and identify missing symbols** - Scan `bundlerLogs` for: - `ReferenceError: X is not defined` → collect symbol names X. - `safety-net stubs for undeclared components: [...]` → collect all listed identifiers. - Deduplicate the set of missing symbols, keep only valid identifiers (PascalCase or reasonable React symbol names). 2. **Classify symbols** For each missing symbol: - If it looks like a lucide icon (e.g. `Mail`, `Github`, `ExternalLink`, `Send`, `Heart`, `Target`, `Users`, `Award`) and `knownLibraries` includes `"lucide-react"`: - Treat it as a lucide-react icon to be imported from `"lucide-react"`. - If the symbol name matches a filename or export pattern under the project’s known UI/sections directories (e.g. `Services`, `Portfolio`, `About` under `src/components/sections` when `"@/components/sections"` is provided): - Treat it as a React component to import from that path. - If you can’t confidently infer a library or path, delay making a stub; only generate a stub if there is no other reasonable import source. 3. **Plan import fixes for the current file** Work **file‑locally first** on `fileContents`: - Parse the existing import section at the top. - For each missing symbol: a. **lucide-react icons** - If there is already an import from `"lucide-react"` like: ```ts import { Users, Award } from "lucide-react"; ``` extend it to include the missing icon: ```ts import { Users, Award, Mail } from "lucide-react"; ``` - If there is no lucide-react import yet, add a new one that includes all missing lucide icons in a single line, sorted alphabetically. b. **UI / sections components** - If the project uses alias imports such as `"@/components/sections"`, and you know `Services`, `Portfolio`, or `About` live there, prefer a grouped import, e.g.: ```ts import { Services, Portfolio, About } from "@/components/sections"; ``` - If components are usually imported individually, match the existing style and add separate imports per component. c. **Other components** - If you truly cannot determine the source, and the symbol appears only a few times as a simple presentational JSX wrapper, you may create a tiny stub in the same file: ```ts const Mail: React.FC<React.SVGProps<SVGSVGElement>> = (props) => ( <span {...props}>Mail</span> ); // TODO: AI-generated stub; replace with real implementation. ``` - Prefer imports over stubs whenever possible. - Do **not** change existing component implementations. Only adjust import lines or add small new components as stubs. 4. **Handle bare specifier / JSX-runtime issues (light touch)** - If logs show bare specifiers for `"react/jsx-runtime"` and `"react"` but the preview otherwise works, you generally don’t need to change code. - Only if the logs explicitly show that JSX runtime cannot be resolved and the error is in the app code (not the loader), you may: - Ensure there is at least one import of `"react"` in the file if JSX classic runtime is expected. - Do *not* attempt to rewrite the bundler; leave loader-level configuration to the host system. 5. **Generate patches** - Output a list of patches as JSON, where each patch has: ```json { "filePath": "src/components/sections/About.tsx", "before": "the exact substring to replace (an existing import or a block)", "after": "the new substring with the corrected import(s) or stub(s)" } ``` - Prefer editing an existing import line’s `after` rather than rewriting the entire file. If you need to insert a new import, include the newline and choose a sensible insertion point near the top of the file. - Ensure: - No duplicate named imports from the same module. - Imports remain syntactically valid TypeScript. - You don’t introduce unused imports (every added symbol should be used). 6. **Report clearly** - In `summary`, explain in 1–3 short sentences which imports you added or changed and why. - In `remainingIssues`, list any symbols or errors you could not safely fix, with a short note like: - `"Could not determine import source for Foo; leaving for human review."` ## Output format Always respond with **valid JSON** like: ```json { "patches": [ { "filePath": "src/components/sections/About.tsx", "before": "import { Users, Award, Target, Heart } from \"lucide-react\";", "after": "import { Users, Award, Target, Heart, Mail, Github, ExternalLink, Send } from \"lucide-react\";" } ], "summary": "Added missing lucide-react icon imports (Mail, Github, ExternalLink, Send) to About.tsx to satisfy JSX usage.", "remainingIssues": "" } ```
