twitter_tweet_details

One tweet as JSON — text, author (followers), likes/replies/retweets/quotes, media, ISO publishedAt. Costs 1 credit. Empty results and failures are never charged. Pass cache=true for a free 24h cache hit (default always fresh).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
urlYesPublic tweet URL, e.g. https://x.com/user/status/ID. The URL platform must match this endpoint's platform. Do not pass cross-platform URLs, e.g. YouTube to TikTok, Instagram to Facebook, LinkedIn to X/Twitter, or Pinterest to Rumble.
cacheNoSet true to serve from the 24h response cache (0 credits on hit). Default false — always fetch fresh.

TDQS

A4.3/5.0
Behavior5/5

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

With no annotations provided, the description fully carries the behavioral burden and does so admirably. It discloses the 1-credit cost, that empty results and failures are never charged, and the exact cache semantics (cache=true gives a free 24h hit, default is always fresh). This is rich, non-obvious operational detail well beyond a simple read action.

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 remarkably efficient: two sentences, front-loaded with the core deliverable, then vital cost and caching rules with zero filler. Every clause earns its place.

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

Completeness5/5

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

For a two-parameter read-only tool with no output schema, the description supplies the essential return fields and clarifies pricing and caching edge cases. The URL parameters are already fully documented in the schema, so the description is complete for an agent to select and invoke the tool correctly.

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 coverage is 100%, and the schema already fully describes both url and cache, including the 0-credit cache-hit behavior. The description restates cache behavior and adds a global credit cost, but it does not truly enhance understanding of the parameters beyond the schema. Baseline 3 is appropriate.

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 clearly states the tool returns one tweet as JSON and enumerates the included fields (text, author, likes/replies/retweets/quotes, media, ISO publishedAt), which distinguishes it from sibling tools like twitter_profile or twitter_user_tweets. However, it lacks an explicit verb like 'get' or 'fetch', so it stops just short of a 5.

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 gives clear context: use this for a single tweet's details, not for profiles, user posts, or transcripts. It also provides practical guidance on when to pass cache=true. It does not explicitly name alternatives or exclusion conditions, so it falls short of a 5.

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