What it does

Esimaccess API is an agent skill from aiskillstore/marketplace. Manage eSIM Access API operations including balance checks, package listing, order creation, eSIM status monitoring, top-ups, cancellations, profile management, webhooks, and refund/reissue workflows. Use when user mentions eSIM, ICCID, data plan, roaming, SIM card, mobile data package, travel connectivity, cellular data usage, or interacts with the eSIM Access API at api.esimaccess.com. Also trigger when user asks about balance, top-up, order status, QR code provisioning, or uploads a list of ICCIDs or order…

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `README.md`, `references/api-reference.md` and `skill-report.json`).

It sits in Backend & APIs, covering Webhooks. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • User mentions eSIM
  • Mobile data package
  • Travel connectivity
  • Cellular data usage

Example prompts

  • “/esimaccess-api”

Requirements

  • Node.js

Workflow steps

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

  1. Order flow: create_order returns orderNo. Poll check_order_status every 3s (4 retries) for ICCID. ORDER_STATUS webhook is fallback.
  2. Top-ups: Use esimTranNo (not ICCID). supportTopUpType === 2 means eligible. Cannot top up after expiry.
  3. Cancel vs Revoke: Cancel works on unused eSIMs (RELEASED/GOT_RESOURCE) and provides refund. Revoke works on activated eSIMs with no refund.
  4. Usage query: Requires esimTranNo, not ICCID. Do an ICCID lookup via /esim/query first if needed.
  5. SMS: Uses message field (not content). Only works on activated eSIMs.

What it can do on your machine

Read from SKILL.md and the folder at commit ad8daf7. 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

    Ships 1 file in scripts/ (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node
    • npx

    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:

    • api.esimaccess.com

    Also links to:

    • console.esimaccess.com

    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

Esimaccess API loads about 1.2k tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 135 tokens; SKILL.md has 469 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~135
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.6k

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); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 469 words (~1,210 tokens).

“Interact with the eSIM Access API for complete eSIM lifecycle management.”
