Read an encyclopedia entry

get_title

Read-onlyIdempotent

Get Anime News Network encyclopedia entries by ID and kind from search_titles, choosing only needed sections like basic, cast, episodes, or news. Supports paginated plot summaries via offset.

Instructions

Read one Anime News Network encyclopedia entry by id. Get the id and kind from search_titles first. Sections are opt-in because a full record is very large: ask only for what you need. 'basic' covers type, vintage, genres, themes, episode count, ratings and the plot summary. Long plot summaries are paginated: when 'truncated' is true, call again with 'offset' set to 'next_offset'.

Input Schema

TableJSON Schema

Name	Required	Description
`id`	Yes	Encyclopedia id, from search_titles.
`kind`	Yes	Which lookup the id belongs to, from search_titles.
`offset`	No	Where to resume the plot summary.
`sections`	No	Which parts to return. 'basic' is usually enough. Adding 'cast' or 'news' can multiply the size of the answer.
`max_chars`	No	Character budget for the plot summary.

`plot_summary`	Yes
`running_time`	Yes
`ending_themes`	Yes
`episode_count`	Yes
`cast_languages`	No	Every language the site records a cast in, with its full credit count, so a trimmed 'cast' still shows what exists. Ask again with a narrower question if a language you need was cut.

TDQS

A4.7/5.0

Behavior5/5

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

Annotations already declare read-only/idempotent/non-destructive behavior; the description adds useful beyond-annotation detail about record size, section opt-in, what 'basic' includes, and the truncated/next_offset pagination protocol. No contradiction with annotations.

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?

Four sentences, no filler, with the core action first followed by workflow, then size guidance, then pagination. Each sentence carries necessary operational detail.

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 read-by-id tool with an output schema and rich annotations, the description covers prerequisite lookup, section selection, size behavior, and pagination. Nothing needed for correct invocation is missing, and the output schema covers return-value details.

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

Parameters4/5

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

Schema description coverage is 100%, so the baseline is 3. The description adds extra meaning by defining what the 'basic' section returns and explaining the pagination loop using a response flag ('truncated', 'next_offset'), which goes beyond the schema's per-parameter descriptions without restating them.

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?

Description states a specific verb and resource ('Read one Anime News Network encyclopedia entry by id'), and clarifies the lookup workflow by pointing to search_titles for obtaining id and kind. This makes it easy to distinguish from the search/list siblings.

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: fetch id/kind from search_titles first, request only needed sections because a full record is large, and resume paginated summaries via offset. It does not explicitly contrast with list_recent or get_news, so it misses the explicit when-not-to-use guidance needed for a 5.

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