What it does

Create Subcommand is an agent skill from DataDog/datadog-agent, published by the product's own GitHub organization. Add a new CLI subcommand to an agent binary (agent, cluster-agent, etc.)

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Datadog. The repository describes itself as: Main repository for Datadog Agent. The licence is Apache-2.0.

“/create-subcommand”

Requirements

Pre-approved tools (allowed-tools): Bash, Read, Write, Edit, Glob, Grep, AskUserQuestion

Workflow steps

5 steps, taken from the step headings in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit 20eff25. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Bash
- Read
- Write
- Edit
- Glob
- Grep
- AskUserQuestion
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
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

Create Subcommand loads about 677 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 233 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~23
When it runs · the whole SKILL.md, loaded when a task matches: ~677

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.

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.

description: Add a new CLI subcommand to an agent binary (agent, cluster-agent, etc.)

argument-hint: [agent] [subcommand-name]
model: sonnet

Add a new CLI subcommand to a Datadog Agent binary. Each agent binary uses Cobra commands registered via a central subcommands.go file.

Agent Binaries

Agent	Subcommands dir	Registration file
Core Agent	`cmd/agent/subcommands/`	`cmd/agent/subcommands/subcommands.go`
Cluster Agent	`cmd/cluster-agent/subcommands/`	`cmd/cluster-agent/subcommands/subcommands.go`
Process Agent	`cmd/process-agent/subcommands/`	`cmd/process-agent/subcommands/subcommands.go`
Security Agent	`cmd/security-agent/subcommands/`	`cmd/security-agent/subcommands/subcommands.go`
System Probe	`cmd/system-probe/subcommands/`	`cmd/system-probe/subcommands/subcommands.go`
DogStatsD	`cmd/dogstatsd/subcommands/`	`cmd/dogstatsd/subcommands/subcommands.go`

Instructions

Step 1: Gather information from the user

Use AskUserQuestion to collect the following. If $ARGUMENTS provides values, skip those questions.

Target agent: Which agent binary? (Core Agent is most common)
Subcommand name: e.g. health, hostname, flare
Description: What does the subcommand do?
Complexity: Simple (no Fx, e.g. version) or with config/IPC (fxutil.OneShot, e.g. hostname)?
Shared across agents?: Yes → pkg/cli/subcommands/<name>/, No → cmd/<agent>/subcommands/<name>/

Step 2: Read reference examples

Read the reference matching the chosen pattern, plus the target agent's registration file:

Pattern	Reference file
Simple (no Fx)	`cmd/agent/subcommands/version/command.go`
With config/IPC	`cmd/agent/subcommands/hostname/command.go`
Shared across agents	`pkg/cli/subcommands/health/command.go` + `cmd/agent/subcommands/health/command.go`

Also read the target agent's command/command.go for available GlobalParams fields.

Step 3: Create the subcommand

Create cmd/<agent>/subcommands/<name>/command.go following the reference patterns exactly.

Step 4: Register

Edit the agent's subcommands.go: add an import with the cmd<Name> alias convention and add cmd<Name>.Commands to the factory slice. Follow the existing entries.

Step 5: Verify

Build: dda inv agent.build --build-exclude=systemd
Test: ./bin/agent/agent <name> --help
Lint: dda inv linter.go

Usage

/create-subcommand — Interactive: prompts for all details
/create-subcommand agent my-command — Pre-fills agent and name
