At a glance

Adding or modifying HTTP REST API endpoints in Golem services.

  • Works in 7 steps: Define the endpoint method → If adding a new API struct → Request/response types → …
  • Creating new endpoints
  • SKILL.md covers Framework, Where Endpoints Live, Adding a New Endpoint and After Modifying Endpoints, plus 1 more section
  • Calls cargo

What it does

Modifying HTTP Endpoints is an agent skill from golemcloud/golem. Adding or modifying HTTP REST API endpoints in Golem services. Use when creating new endpoints, changing existing API routes, or updating request/response types for the Golem REST API.

Its SKILL.md is about 1.2k 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 REST APIs and OpenAPI specifications. It works with OpenAPI. The repository describes itself as: Golem Cloud is the agent-native platform for building AI agents and distributed applications that never lose state, never duplicate work, and never require you to build…

When your agent uses it

  • Creating new endpoints
  • Changing existing API routes
  • Updating request/response types for the Golem REST API

Example prompts

  • “/modifying-http-endpoints”

Workflow steps

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

  1. Define the endpoint method
  2. If adding a new API struct
  3. Request/response types
  4. Regenerate OpenAPI specs
  5. Rebuild golem-client
  6. If new types are used in the client
  7. Verify affected behavior

What it can do on your machine

Read from SKILL.md and the folder at commit 2dea6b9. 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:

    • cargo

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

  • Network

    Links to these hosts (documentation or services it may open):

    • learn.golem.cloud

    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

Modifying HTTP Endpoints loads about 1.2k tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 518 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 518 words (~1,175 tokens).

“Golem uses Poem with poem-openapi for REST API endpoints. Endpoints are defined as methods on API structs annotated with #[OpenApi] and #[oai].”
