Get upcoming season anime

get_upcoming_season

Read-only

List anime scheduled for the upcoming season, with filters for media type, content rating, and adult or kids content.

Instructions

List anime scheduled for the upcoming season. Use get_seasonal_anime for the current or a specific past season. If Tenrai is unavailable and MAL_CLIENT_ID is set, transparently retries via the official API — filter/rating/unapproved/continuing/kids are silently dropped (no equivalent there), order_by/sort keep only the default members-descending order (anything else comes back unsorted), themes/demographics/broadcast come back empty, and sfw_strict degrades to the same filtering as sfw there (no Ecchi-genre distinction available).

Input Schema

Name	Required	Description
`sfw`	No	If true, exclude adult/explicit-rated entries (R+ Mild Nudity and up). Defaults to false (no filtering). Note: this alone still allows mainstream, safely-rated shows tagged with the Ecchi genre (fanservice) through — use `sfw_strict` to also exclude those.
`kids`	No	If true, exclude entries tagged as children's/kids content. Defaults to false.
`page`	No	1-based page number for pagination (1-20000).
`sort`	No	Sort direction. Only takes effect together with `order_by`; ignored on its own.
`limit`	No	Max results per page (1-100).
`filter`	No	Restrict to one or more media types.
`rating`	No	Restrict to one or more specific content ratings. More granular than `sfw`/`sfw_strict` — use this to target a precise rating band instead of a blanket adult-content cutoff.
`order_by`	No	Field to order by. Defaults to members.
`continuing`	No	If true, also include TV series continuing from a previous season. Defaults to false.
`sfw_strict`	No	If true, exclude adult/explicit-rated entries AND anything tagged with the Ecchi genre, even otherwise-mainstream/safely-rated shows. Stricter than `sfw` alone. Defaults to false.
`unapproved`	No	Entries not yet approved by MAL's moderators: 'true' also includes them, 'false' (default) excludes them, 'only' returns exclusively unapproved entries.

Output Schema

Name	Required	Description	Default
`page`	Yes
`results`	Yes

TDQS

A4.6/5.0

Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered; the description goes well beyond by disclosing the automatic fallback to the official API. It lists exactly which parameters are dropped, which return unsorted, which come back empty, and how sfw_strict degrades — genuinely useful behavioral detail. It stops short of stating latency, rate limits, or whether the fallback is visible in the response.

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?

The purpose and the sibling routing are front-loaded, which is exactly right. The trailing fallback sentence is a dense run-on, but each clause carries distinct operational information rather than filler, so the length is mostly justified.

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?

With 11 optional parameters and an output schema, the description does not need to explain return values, and it covers the two things that matter most: when to prefer the sibling, and how behavior changes on fallback. An agent has everything needed to call this correctly.

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 coverage is 100%, so the baseline is 3, but the description adds semantics the schema cannot: the fallback-specific fate of filter, rating, unapproved, continuing, kids, order_by/sort, and the sfw_strict degradation. Minor deduction because it references themes/demographics/broadcast, which are not parameters in this schema, which could confuse an agent about what it can actually pass.

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 first sentence states a specific verb and resource with a clear scope: anime scheduled for the upcoming season. It also explicitly names the sibling it is not (get_seasonal_anime for current/past seasons), so an agent can route correctly without opening either schema.

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

Usage Guidelines5/5

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

It gives an explicit when-to-use-other rule: use get_seasonal_anime for the current or a specific past season, leaving this tool for the upcoming one. The fallback conditions (Tenrai unavailable + MAL_CLIENT_ID set) further tell the agent what to expect in each situation.

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