What it does

Commandkit is an agent skill from neplexlabs/commandkit. Build and maintain Discord bots with CommandKit core conventions. Use when implementing command/event architecture (including hierarchical subcommands), middleware chains, JSX components, and commandkit.config setup for plugin-based features.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including reference files (for example `README.md`, `references/00-filesystem-structure.md` and `references/01-config-and-structure.md`).

It sits in Frontend & Design, covering React components and Messaging and chat bots. The repository describes itself as: The discord.js meta-framework with features such as AI-powered command handler, analytics, feature flags, and more. The licence is MIT.

When your agent uses it

  • Implementing command/event architecture (including hierarchical subcommands)
  • Middleware chains
  • Commandkit.config setup for plugin-based features

Example prompts

  • “/commandkit”

Requirements

  • Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Validate structure and baseline config first.
  2. Place command/event files in convention paths.
  3. Implement command logic with typed context and metadata.
  4. Add middleware only for cross-cutting concerns.
  5. Verify runtime behavior with local dev command.

What it can do on your machine

Read from SKILL.md and the folder at commit d771e6b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (JavaScript), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Commandkit loads about 1k tokens when it runs, and up to ~6.2k if it reads all its reference files. Until then it costs about 63 tokens; SKILL.md has 292 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~6.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

CommandKit Core

Activation guidance

Use this skill for framework-level architecture and implementation:

  • command and event file placement
  • commandkit.config strategy and plugin wiring
  • middleware lifecycle behavior
  • JSX interaction components and handlers
  • project structure validation and migration to convention-based layouts

Required filesystem expectations

  • commandkit.config.ts (or .js) at project root
  • src/app/commands/** for commands
  • src/app/events/** for events
  • optional plugin-specific folders (src/app/locales, src/app/tasks, src/workflows) when those plugins are enabled

Configuration expectations

  • Use defineConfig from commandkit/config.
  • Register plugins explicitly in plugins: [].
  • Use startup guards like noBuildOnly() for runtime-only setup (for example task/driver init).
  • Keep environment-sensitive plugin toggles explicit.

Execution workflow

  1. Validate structure and baseline config first.
  2. Place command/event files in convention paths.
  3. Implement command logic with typed context and metadata.
  4. Add middleware only for cross-cutting concerns.
  5. Verify runtime behavior with local dev command.

Guardrails

  • Do not invent CommandKit APIs.
  • Avoid registration-heavy patterns that bypass convention discovery.
  • Keep handlers small and move reusable logic to helpers/services.

Can I use Commandkit in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add neplexlabs/commandkit --skill commandkit -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/commandkit, .gemini/skills/commandkit, .github/skills/commandkit and .opencode/skills/commandkit in your project.

What does Commandkit need to run?

Going by SKILL.md and its folder, Commandkit needs JavaScript for the scripts in its folder. Our summary lists: Node.js.

Does Commandkit access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Commandkit safe to install?
