At a glance

Turn any API into a CLI command. An agent skill from ShawnPana/aurl.

  • Works in 3 steps: aurl [name] --help — scan all endpoints… → aurl [name] describe METHOD /path — read… → Make the request — enum params are…
  • Tasks that involve OpenAPI specifications
  • SKILL.md covers Commands, Using a Registered API, Discovery Workflow and Notes
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Aurl is an agent skill from ShawnPana/aurl. Turn any API into a CLI command. Register OpenAPI or GraphQL endpoints by name, then explore and invoke them. Built for AI agents to use APIs like tool calls.

Its SKILL.md is about 540 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 GraphQL. It works with OpenAPI and GraphQL. The repository describes itself as: A command line tool for turning any API into a CLI command, supporting OpenAPI 3.0, OpenAPI 3.1, Swagger 2.0, and GraphQL. aurl auto-detects authentication, validates requests… The licence is MIT.

When your agent uses it

  • Tasks that involve OpenAPI specifications
  • Tasks that involve GraphQL

Example prompts

  • “/aurl”

Workflow steps

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

  1. aurl [name] --help — scan all endpoints grouped by tag
  2. aurl [name] describe METHOD /path — read full docs for an endpoint before calling it
  3. Make the request — enum params are validated before sending, missing required body fields trigger a warning

What it can do on your machine

Read from SKILL.md and the folder at commit 99c2bc0. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    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

Aurl loads about 536 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 117 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~536

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.

aurl

Turn any API spec into a CLI command. Register APIs by name, explore their endpoints, and make requests.

Commands

bash
aurl add [name] [openapi.json URL or path]       # register an API
aurl add [name] [spec] --base-url [URL]           # override base URL
aurl add [name] [spec] --header "Key: Value"      # manual auth header
aurl add --graphql [name] [endpoint]              # register a GraphQL API
aurl list                                          # list registered APIs
aurl remove [name]                                 # unregister
aurl auth [name]                                   # reconfigure auth

Using a Registered API

bash
aurl [name] --help                                # see all endpoints, params, enums, response codes
aurl [name] describe METHOD /path                 # detailed docs for one endpoint
aurl [name] describe [field]                      # detailed docs for a GraphQL field/type
aurl [name] docs                                  # open external docs in browser
aurl [name] METHOD /path                          # make a REST request
aurl [name] METHOD /path '{"key":"value"}'        # make a REST request with JSON body
aurl [name] '{ graphql query }'                   # run a GraphQL query
aurl [name] '{ query }' '{"var":"val"}'           # GraphQL with variables

Discovery Workflow

When working with an unfamiliar registered API:

  1. aurl [name] --help — scan all endpoints grouped by tag
  2. aurl [name] describe METHOD /path — read full docs for an endpoint before calling it
  3. Make the request — enum params are validated before sending, missing required body fields trigger a warning

Notes

  • Auth is auto-detected from the spec's securitySchemes during aurl add
  • Query params go inline in the path: aurl [name] GET '/path?key=value'
  • Quote paths with ? to prevent shell globbing
  • On 4xx errors, the CLI suggests the expected request body from the spec
