Input Schema

TableJSON Schema

Name	Required	Description
`url`	No	Public Facebook profile or page URL whose reels should be listed.
`link`	No	Alias for `url`. Prefer `url`.
`path`	No	Alias for `url`. Prefer `url`.
`trim`	No	Ignored if this tool does not support it.
`limit`	No	Ignored if this tool does not support it.
`cursor`	No	Opaque pagination cursor from a previous response.
`offset`	No	Ignored if this tool does not support it.
`context`	Yes	Describe the user's underlying goal in one sentence — not the tool you are calling.
`tweetId`	No	Alias for `url`. Prefer `url`.
`pageSize`	No	Ignored if this tool does not support it.
`tweetUrl`	No	Alias for `url`. Prefer `url`.
`tweet_id`	No	Alias for `url`. Prefer `url`.
`hostMedia`	No	When true, hosts source media for 90 days and returns delivery URLs in each reel's `hostedMedia`.
`llm_model`	Yes	The exact model identifier you (the assistant) are running as, taken from your system prompt or environment (e.g. "claude-opus-4-8", "gpt-5.2"). Used for analytics only. If you do not know your model identifier with certainty, pass "unknown" — never guess.

`maxResults`	No	Ignored if this tool does not support it.
`max_results`	No	Ignored if this tool does not support it.
`conversation_id`	No	Echo the conversation_id from the server's previous response. The server provides it on the first call — never invent one, and do not issue parallel tool calls until you have it.

A4.2/5.0

Behavior4/5

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

Annotations declare readOnlyHint=true and openWorldHint=true, so the safety profile is already known. The description adds valuable behavioral context beyond annotations: the credit cost structure (1 base, +2 per hosted asset up to 24/49 max), the fact that failed assets are not surcharged, and that hostMedia=true hosts media for 90 days and returns delivery URLs. This is meaningful operational transparency. It doesn't mention pagination behavior or rate limits, but the openWorldHint and readOnlyHint cover the main safety aspects.

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

Conciseness5/5

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

Three sentences with zero waste. The core action and input are front-loaded, followed by the credit cost detail and the failed-assets note. Every sentence earns its place. The cost information is compactly expressed and the 'up to 24 / 49 max' is precise.

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?

For a read-only list tool with 100% schema coverage and no output schema, the description covers the essential operational details: what it lists, what input it accepts, and the cost implications of hostMedia. The main gap is that it doesn't describe the return format or pagination behavior, but since there's no output schema and the tool is a simple list operation, the description is largely complete. The cost transparency is a strong addition.

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 the schema already documents all 19 parameters. The description adds meaning for hostMedia (explains the +2 credit surcharge and 90-day hosting) and url (accepts profile or page URL), which goes slightly beyond the schema. However, most parameters are aliases or 'ignored' fields that the schema already explains. Baseline 3 is appropriate since the schema does the heavy lifting and the description adds only marginal semantic value.

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

Purpose5/5

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

The description states a specific verb ('List'), a specific resource ('Reels from a Facebook profile or Page'), and the input form ('Accepts a profile or page URL'). It clearly distinguishes from siblings like facebook_profile_posts_list and facebook_profile_photos_list by naming the exact content type. The title reinforces the same, but the description adds the Page scope and URL input detail.

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

Usage Guidelines4/5

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

The description implies when to use it: when the user wants reels from a Facebook profile or Page, given a URL. It doesn't explicitly name alternatives or exclusions, but the sibling set makes the context clear (e.g., facebook_profile_posts_list for posts, instagram_profile_reels_list for Instagram). The credit/cost note also gives practical usage context. Missing explicit 'use X instead when...' guidance, so not a 5.

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