Instagram: Get a highlight and its stories

instagram_highlight
Read-onlyIdempotent

Get a saved Instagram highlight and its available stories, including media variants, publish times, author details, mentions, links and shared posts. Saved highlights do not expire. Stories are not paginated: every story in the highlight comes back in one response. Read-only: returns public data and changes nothing. Costs 1 credit per request.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {
      "highlightId": "<highlightId>"
    },
    "name": "instagram_highlight"
  }
}

Input Schema

NameRequiredDescriptionDefault
cacheOnlyNoReturn only a cached result and never scrape live. With `cacheMaxAgeHours`, only a result that recent is returned; without it, the latest cached result of any age. Responds 404, at no cost, when there is none, e.g. true.
highlightIdYesNumeric highlight ID, highlight:<ID>, or an Instagram stories/highlights link.
cacheMaxAgeHoursNoAccept a cached result scraped up to this many hours ago. A cached result costs no credits, and its `cachedAt` says when it was scraped. When no cached result is that recent, the data is scraped live at the normal price. Leave it out to always scrape live, e.g. 24.

A3.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare read-only, idempotent, open-world, non-destructive, so the description correctly focuses on traits annotations cannot express: highlights never expire, stories are never paginated and arrive in one response, only public data is returned, and each request costs 1 credit. The pagination and billing notes are genuinely decision-relevant; only caching behavior (covered in schema) is left unaddressed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with purpose, then behavior, then cost — the ordering an agent needs. Four tight sentences with no filler; the media field enumeration is slightly list-heavy but substitutes for the absent output schema, so it earns its space.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description usefully characterizes the return payload shape, and it closes the loop on the two things an agent would otherwise guess wrong about — pagination and cost. A brief note on what happens when a highlight is private or empty would make it fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so highlightId formats and the cacheOnly/cacheMaxAgeHours semantics are already fully documented. The description adds no parameter-level meaning beyond the schema, which is the expected baseline here.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource ('Get a saved Instagram highlight and its available stories') and enumerates the payload (media variants, publish times, author details, mentions, links, shared posts). This distinguishes it from the sibling instagram_stories by qualifying 'saved highlight', though it never names that sibling to make the split explicit.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied rather than stated: an agent can infer this is the tool for fetching stories inside an existing highlight, and that it needs an ID or link. There is no explicit when-to-use versus instagram_stories or instagram_highlights (to discover highlight IDs first), and no exclusions or prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
