+# CyberChef Agent Development Guide
+
+## Project
+
+CyberChef is a client-side web app and Node.js package for encoding, decoding, encryption, compression, parsing, and data analysis operations. Users build recipes from operations and run them against browser-local input.
+
+Core principles for changes:
+
+- Keep operations and features client-side, avoiding external services whenever possible. CyberChef is used on airgapped networks.
+- Keep latency low. Keep large libraries in separate modules so they are downloaded only by users who invoke the relevant operations.
+- Prefer Vanilla JS over jQuery or other frameworks.
+- Avoid new external package dependencies unless absolutely necessary. Reuse platform APIs and existing project utilities first.
+
+## Commands
+
+CyberChef expects Node.js `>=24 <25`.
+
+- Install: `npm install`
+- Development server: `npm start`
+- Production build: `npm run build`
+- Build Node package artifacts: `npm run node`
+- Lint: `npm run lint`
+- Spell/grammar lint for `src`: `npm run lint:grammar`
+- Full non-UI test suite: `npm test`
+- UI tests: `npm run testui`
+- UI tests against the dev server: `npm run testuidev`
+- Node REPL: `npm run repl`
+
+## New operations
+
+Use the existing generator for new operations:
+
+```bash
+npm run newop
+```
+
+This wraps `node src/core/config/scripts/newOperation.mjs`. Run it from the repository root. Afterwards:
+
+- Implement the operation in `src/core/operations/<Operation>.mjs`.
+- Add or verify its category entry in `src/core/config/Categories.json`.
+- Implement the tests in `tests/operations/tests/<Operation>.mjs`.
+
+## Coding conventions
+
+* Indentation: Each block should consist of 4 spaces
+* Object/namespace identifiers: CamelCase
+* Function/variable names: camelCase
+* Constants: UNDERSCORE_UPPER_CASE
+* Source code encoding: UTF-8 (without BOM)
+* All source files must end with a newline
+* Line endings: UNIX style (\n)
+
+## Operation argument validation and errors
+
+Use the existing operation recipe validation framework. Declare constraints in operation `ingList` entries via operation `args` so `Ingredient` and `Operation.validateIngredients()` can enforce them before `run()` executes. Do not use checks inside `run()` when a constraint belongs in argument metadata.
+
+For invalid arguments and failures caused by user input, throw `OperationError` from `src/core/errors/OperationError.mjs`. Recipe execution treats `OperationError` as expected output, and is not appropriate for programmer bugs or unexpected internal exceptions.
+
+## Testing instructions
+
+Bug fixes require regression tests that must fail before the fix and pass after it. New features require tests including edge cases and invalid input. Use both NodeJS tests and UI tests when a change affects both the operation/API behaviour and browser interaction.
+
+- Operation tests live under `tests/operations/tests/` and are run by `npm test` through `tests/operations/index.mjs`.
+- Node API tests live under `tests/node/tests/` and are run by `npm test` through `tests/node/index.mjs`.
+- UI tests live under `tests/browser/` and are run with `npm run testui` or `npm run testuidev`.
+
+## Security
+
+- Avoid prototype pollution. Utilise `Object.create(null)`, `Map`, and `Object.prototype.hasOwnProperty.call(...)`.
+- Avoid XSS. Escape strings before rendering and prefer text APIs over `innerHTML`.
+- Avoid resource exhaustion. Bound input sizes, counts, recursion depth and loop iterations.
+
+## Issue and pull request policy
+
+Do not open GitHub issues or pull requests on behalf of users. If a user asks to create an issue or pull request, stage a root-level file named `AI_MARKER`.
