At a glance

Resolve the real request URL of an API resource on a live Blockscout instance (service:name + instance → full URL).

  • Works in 5 steps: Inputs → Repo → path template → Repo → which env vars build the URL → …
  • A request must be made to
  • SKILL.md covers Step 0 — Inputs, Step 1 — Repo → path template, Step 2 — Repo → which env vars… and Step 3 — Instance → host +…, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Resolve API URL is an agent skill from blockscout/frontend. Resolve the real request URL of an API resource on a live Blockscout instance (service:name + instance → full URL). Use whenever a request must be made to, or a sample response fetched from, a deployed instance's API.

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Front-end application for Blockscout chain explorer.

When your agent uses it

  • A request must be made to
  • A sample response fetched from
  • A deployed instances API

Example prompts

  • “/resolve-api-url”

Workflow steps

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

  1. Inputs
  2. Repo → path template
  3. Repo → which env vars build the URL
  4. Instance → host + real values
  5. Assemble

What it can do on your machine

Read from SKILL.md and the folder at commit 9438622. 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 typescript).

    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

Resolve API URL loads about 865 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 418 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~865

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 418 words (~865 tokens).

“A request URL is assembled as (+ compiled path params,”
