What it does

Add Namespace is an agent skill from swagger-api/apidom. Creates a new namespace package for a new API specification version in the ApiDOM monorepo

Its SKILL.md is about 8.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering OpenAPI specifications and Monorepo tooling. It works with OpenAPI and JavaScript. The repository describes itself as: Semantic parser for API specifications.

When your agent uses it

Example prompts

“Use the add-namespace skill to create a new namespace package for a new API specification version in the ApiDOM monorepo”
“/add-namespace”

Workflow steps

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

Gather Information
Create Package Structure
Generate Core Files
Copy Supporting Files
Generate Tests
Build and Test
Update Root Configuration

What it can do on your machine

Read from SKILL.md and the folder at commit 8505e65. 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
Shell commands in SKILL.md call:
- npm
- curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- spec.openapis.org
- registry.npmjs.org
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

Add Namespace loads about 8.1k tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 1,448 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~26
When it runs · the whole SKILL.md, loaded when a task matches: ~8.1k

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,448 words (~8,130 tokens).
