Acronym Expander Skill

Overview

The Acronym Expander API resolves an acronym to its full meaning using a two-tier lookup: first checking a built-in dictionary of 28 common acronyms (technology, business, and general terms like API, CEO, FAQ), then falling back to an AI model when the input isn't in the dictionary. The `source` field on every response tells you which path was taken — `dictionary` for direct hits, `ai` for AI-generated expansions. Dictionary hits always return exactly one expansion; AI responses return up to three in descending order of likelihood. An optional `context` parameter (paid plans only) refines the AI path by biasing the model toward a specific domain — it has no effect on dictionary hits, which are deterministic and ignore context entirely.

The tool

Once your client is connected to the VerveKit server, this appears in its tool list as AcronymExpanderSkill. It is read-only and open-world — it fetches and never mutates anything on your side — so most clients call it without asking you to confirm.

Tool call

{
  "name": "AcronymExpanderSkill",
  "arguments": {
    "acronym": "API"
  }
}

You do not name the tool yourself; the model picks it. Asking about API in the terms this skill covers is enough for it to reach for AcronymExpanderSkill on its own — naming it explicitly also works, and is the way to force the call.

Connecting

One server URL covers every skill in the catalog, including this one. Authorization is OAuth: the client opens a browser once, and there is no key to paste into a config file.

{
  "mcpServers": {
    "vervekit": {
      "url": "https://api.vervekit.com/v1/mcp"
    }
  }
}

Per-client setup — Claude, Cursor, VS Code, ChatGPT — is on the MCP setup page.

Arguments

These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made. Premium arguments are accepted on every plan but only take effect on plans that include them.

Argument	Type	Description
`acronym`Required	string	The acronym to expand (max 20 characters) length 0–20
`context`OptionalPremium	string	Optional context to help determine the correct meaning default General

What the model gets back

The result carries a structuredContent object matching the tool's declared outputSchema, so a client reads fields without parsing prose. status is "ok" and error is null on success; a null field means the value was not available for that input, not that the call failed.

Result

{
  "status": "ok",
  "error": null,
  "data": {
    "acronym": "API",
    "expansions": [
      {
        "expansion": "Application Programming Interface",
        "description": "A set of protocols for building software",
        "category": "technology"
      }
    ],
    "most_common": {
      "expansion": "Application Programming Interface",
      "description": "A set of protocols for building software",
      "category": "technology"
    },
    "source": "dictionary",
    "context_provided": "software"
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Field	Type	Example	Description
`acronym`	string	`API`	The acronym that was expanded Echoes the acronym from the request preserving the original casing — not the upper-cased form used internally for the dictionary lookup.
`expansions`	array[1]		List of possible acronym expansions with descriptions For dictionary hits (source='dictionary'), always contains exactly one entry. For AI responses (source='ai'), contains up to three entries in descending order of likelihood. The order is determined by the AI model and is not guaranteed to be stable across identical repeat calls.
`expansions.0.expansion`	string	`Application Programming Interface`	The full expansion of the acronym meaning
`expansions.0.description`	string	`A set of protocols for building software`	Description explaining what the expansion means
`expansions.0.category`	string	`technology`	Category or domain the acronym belongs to
`most_common`Premium	object	`{…}`	The most common or likely expansion for the acronym Equals expansions[0] when expansions has at least one entry. Returns null (not omitted) when the AI path returns an empty expansions array.
`most_common.expansion`Premium	string	`Application Programming Interface`	Most common expansion of the provided acronym
`most_common.description`Premium	string	`A set of protocols for building software`	Detailed description of the most common expansion
`most_common.category`Premium	string	`technology`	Category or domain for the most common expansion
`source`	string	`dictionary`	Source where the expansion data was retrieved from Either 'dictionary' or 'ai'. Use this to distinguish deterministic responses (dictionary — instant, identical across calls) from AI-generated ones (variable latency, may produce slightly different wording on repeat calls due to non-zero AI temperature).
`context_provided`	string	`software`	The context used to determine acronym meaning Echoes the resolved context value used by the request — typically 'General' when omitted, or the provided value otherwise. Useful for confirming the context the API actually used; ignored for dictionary hits.

Failure modes

Errors come back as tool errors carrying a sentence the model can act on, not a bare status code. Error handling covers the full list.

Status	What it means
`400` / `422`	The arguments did not validate. The message names the offending one.
`401`	The OAuth session is invalid or expired — reconnect the server.
`403`	Blocked by a key restriction or an IP allow-list. Never a bad identity.
`404`	This skill is not part of VerveKit. Check the catalog.
`429`	Out of credits, or a brief rate limit. The message tells them apart.

A call costs 10 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.
