# hono A skill that feeds the agent Hono API knowledge and makes it verify apps through Hono CLI instead of throwaway scripts. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 2900 installs · ★ 16 - Author: honojs - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/honojs/skills/tree/HEAD/skills/hono/SKILL.md - Updated: 2026-10-15 - HTML: https://affpapa.org/en/nevibecode/skills/honojs-hono ## What it does The skill puts a Hono reference straight into the agent's context: the app constructor, routing methods, path parameters and regex constraints, route grouping, error handling, context methods like `c.json` and `c.redirect`, headers and request-scoped variables. When code imports from `hono` or `hono/*`, the agent picks this up on its own. Verification runs through Hono CLI, not throwaway scripts or a dev server. Install it as a dev dependency with `npm install -D @hono/cli@next`, then read `npx hono --help`. `npx hono routes` lists the routes, `npx hono request /path` sends one request with no server running. If the app is not at `src/index.ts`, pass the file to every command: `npx hono request / src/app.ts`. Do not put credentials in CLI arguments — use environment variables for sensitive values. For a stateful flow there is `npx hono batch -`: one JSON object per line, and a saved value can be reused as `{{id}}` in a later step. Before touching existing routes, capture current behavior with `npx hono snapshot`, then rerun those lines through `batch` until `"failed": 0`. On a large API, `--status-only` and `--compact` keep the output small. The skill assumes Hono CLI is available; projects from `create-hono` already ship it. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add honojs/skills --skill hono -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/hono/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/hono/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add honojs/skills --skill hono -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/hono/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add honojs/skills --skill hono -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/hono/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install honojs/skills hono ``` 2. **Manually: put the files in place** - File: `.github/skills/hono/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add honojs/skills --skill hono -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/honojs/skills --path skills/hono ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/hono/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add honojs/skills --skill hono -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/honojs/skills/tree/HEAD/skills/hono/SKILL.md ## When to use it - learn Hono routing without digging through the docs - test a route with a single request and no server - capture current API behavior before a refactor - run a POST-then-GET flow that reuses the returned id - shrink check output on a large API ## Example prompts - list every route in the app with hono routes - send a POST to /users and check it returns 201 - snapshot the current routes, then change the handler ## Source text · SKILL.md · MIT Below is the content of a third-party file.

This skill provides inline API knowledge for AI. Use Hono CLI to inspect and test the app. ## Latest Documentation For details beyond this inline reference, fetch the latest documentation from https://hono.dev.

It is a dev dependency (projects from `create-hono` already have it), loads the app in-process with `app.request()`, and prints JSON. Install it if missing, then read its help: ```bash npm install -D @hono/cli@next npx hono --help ``` Follow the note at the top. It explains the JSON output contract and the workflow. `npx hono --help` has examples and notes for each command (`routes`, `request`, `batch`, `snapshot`, `benchmark`, `ssg`, `init`). Notes: - `npx hono routes` lists the routes; `npx hono request /path` sends one request — no server needed. If the app is not at the default path (`src/index.ts`), pass the file to every command: `npx hono request / src/app.ts`. Do not pass credentials directly in CLI arguments; use environment variables for sensitive values. - Cloudflare bindings (KV, D1, R2, vars) reach `c.env` automatically — no server, no flag. In a project with `cloudflare.config.ts` (the `cf` CLI) and a Vite config, `request`, `batch`, and `snapshot` run through the Vite dev server by default, and `c.env` has the local bindings; `request` and `batch` default to Vite as well in a Vite project with no `src/index.*` (an app built by a Vite plugin; `snapshot` still needs the file), and `--runtime vite` selects it explicitly. In a project with a wrangler config, the app runs on Node.js with the real local bindings loaded; for the full Workers runtime there, add `--runtime workerd` (pass no file argument; the entry is `main` in the wrangler config). `--trace`, `--watch`, and a file argument run the app on Node.js, where `c.env` is empty in a `cf` project. - `routes` and `snapshot` also load apps that import `cloudflare:workers` (Durable Objects); the import is stubbed while the routes are read. ```` END THIRD-PARTY FILE ec4bb49481036184 The third-party file has ended.
