typescript-development

v2.3.0

TypeScript and JavaScript development toolkit - hands-on typescript-engineer agent (architecture + implementation), dead-code detection via Knip, coding standards enforcement, and enterprise-grade TypeScript mastery (type system, generics, React/NestJS integration, Zod validation, modern toolchain), and a type-safety review layer: adversarial type-safety-auditor agent, 20-rule type-safety-rules skill, and /review-typescript command with tsc/ESLint ground truth

Install plugin

Installs for the current user
codex plugin marketplace add IchenDEV/agent-plugin-mkt
codex plugin marketplace upgrade agent-plugin-marketplace
codex plugin add typescript-development-2@agent-plugin-marketplace

Paste and run these commands in a terminal with Codex. They add and refresh the PluginsMP catalog, then install this plugin.

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Get the source manually
git clone https://github.com/acaprino/daodan

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The plugin root is exports/codex/plugins/typescript-development/.

Included Skills4

knipskills/knip/SKILL.md

Run Knip to find unused files, exports and types, with per-framework and per-test-runner plugins. TRIGGER WHEN: cleaning up TypeScript/JavaScript codebases, optimizing bundle size, or enforcing strict dependency hygiene in CI. DO NOT TRIGGER WHEN: the target is a Python codebase (use python-dead-code).

mastering-typescriptskills/mastering-typescript/SKILL.md

Deep reference for advanced TypeScript. TRIGGER WHEN: migrating JavaScript to TypeScript, bootstrapping a TS project (strict tsconfig, ESLint, Vite/Vitest, pnpm), writing generics, mapped or conditional types, `satisfies`, branded types, discriminated unions or template literal types, designing Zod schemas for runtime validation, building type-safe NestJS APIs, deep React and TypeScript typing, typing LangChain.js, or comparing TS with Java/Python enterprise approaches. DO NOT TRIGGER WHEN: routine TS/JS (use typescript-development:typescript-write), React performance (use react-development:review-react), or dead-code detection (use typescript-development:knip).

type-safety-rulesskills/type-safety-rules/SKILL.md

20 rules across 7 categories, each with detection and fix guidance. TRIGGER WHEN: reviewing or hardening TypeScript against type-system erosion: `any` leakage, unsound casts, missing boundary validation, assertion abuse, tsconfig strictness, exhaustiveness and generics soundness. DO NOT TRIGGER WHEN: style and naming review (use typescript-write), or dead-code detection (use knip).

typescript-writeskills/typescript-write/SKILL.md

Apply house coding standards to everyday application work. TRIGGER WHEN: writing or reviewing TypeScript/JavaScript code, including types, generics, async patterns, module boundaries, and style conventions. DO NOT TRIGGER WHEN: React performance (use react-development), or advanced type-system depth (use mastering-typescript).
