Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
urlNoList permalink or numeric id.
linkNoAlias for `url`. Prefer `url`.
pathNoAlias for `url`. Prefer `url`.
trimNoIgnored if this tool does not support it.
limitNoIgnored if this tool does not support it.
offsetNoIgnored if this tool does not support it.
contextYesDescribe the user's underlying goal in one sentence — not the tool you are calling.
tweetIdNoAlias for `url`. Prefer `url`.
pageSizeNoIgnored if this tool does not support it.
tweetUrlNoAlias for `url`. Prefer `url`.
tweet_idNoAlias for `url`. Prefer `url`.
llm_modelYesThe 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.
permalinkNoAlias for `url`. Prefer `url`.
tweet_urlNoAlias for `url`. Prefer `url`.
maxResultsNoIgnored if this tool does not support it.
max_resultsNoIgnored if this tool does not support it.
conversation_idNoEcho 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.

  2. Added

TDQS

B3.3/5.0
Behavior3/5

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

The annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered structurally. The description adds no additional behavioral context such as what the returned list object contains, whether pagination applies, or any rate-limit or authentication considerations; it is not contradictory.

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?

The description is a single sentence with no filler or repetition. The verb, resource, and lookup mechanism are all front-loaded, making it immediately scannable for an agent.

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

Completeness3/5

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

With no output schema, the description does not clarify what 'get a list' returns (metadata, membership, etc.), leaving some ambiguity among the sibling list tools. However, the schema thoroughly documents parameters and the annotations cover safety, so the definition is minimally adequate for a simple read tool.

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 17 parameters, including aliases and the meaning of url as 'List permalink or numeric id.' The description's mention of 'by URL or id' largely restates the schema rather than adding new semantic value, matching the baseline for high schema coverage.

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 states a specific verb ('Get'), resource ('an X list'), and lookup method ('by URL or id'), so an agent can see this is a read operation on a Twitter/X list. It does not explicitly distinguish itself from sibling tools like twitter_list_tweets_list or twitter_list_members_list, but the object is clearly the list itself.

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

Usage Guidelines2/5

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

There is no guidance about when to use this tool versus the many sibling Twitter/X list tools, such as twitter_list_followers_list or twitter_list_tweets_list. The only usage hint is that the list can be identified by URL or id, which is a parameter concern rather than a tool-selection criterion.

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