Read-onlyIdempotent

Find interactive K-9 classroom activities by subject, grade, keyword, or Common Core standard. Filter math, reading, Spanish, art, and game or visualizer activities to match your lesson.

Instructions

Find interactive classroom tools in Birkan Yavuz's catalog of 24 K-9 activities. Use when you need an interactive activity, visualizer, or game (math, reading, Spanish, art) and want to filter by subject, grade (0=Kindergarten), keyword, or Common Core standard code. Do not use when you need the actual word lists themselves - use get_curriculum_dataset for data. Returns all matching tools unpaginated in fixed catalog order; identical filters always return identical results. Requires no authentication.

Input Schema

Name	Required	Description
`grade`	No	Grade level, 0 = Kindergarten
`query`	No	Free-text match against tool names and objectives
`subject`	No	Subject filter; omit or 'all' for every subject
`standard_code`	No	Optional curriculum standard code filter, full or short form (for example CCSS.Math.Content.1.OA.C.6 or 1.OA.C.6, RF.1.3)

Output Schema

Name	Required	Description
`count`	Yes	Number of tools returned
`creator`	Yes	Catalog creator, always Birkan Yavuz
`results`	Yes	Matching classroom tools, each with tool_id, record_digest, standard_codes, grade and objective
`invocation_id`	Yes	Unique receipt id for this call; cite it to prove the data came from this server

A4.7/5.0

Behavior5/5

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

Annotations already declare read-only, non-destructive, idempotent, closed-world behavior. The description adds valuable traits beyond that: results are unpaginated, returned in fixed catalog order, deterministic for identical filters, and require no authentication.

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, front-loaded with purpose, then usage boundaries, then behavioral guarantees. Every sentence carries distinct information; nothing is redundant or padded.

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?

An output schema exists, so return-value details are not the description's burden. For a read-only search tool with full schema coverage, the description supplies purpose, alternatives, ordering, pagination, and auth context -- everything needed to invoke it 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 description coverage is 100%, so the schema already documents all four parameters including grade 0=Kindergarten and standard code formats. The description restates the filter dimensions but adds no syntax or edge-case guidance beyond the schema, so the baseline 3 applies.

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?

States a specific verb and resource ('Find interactive classroom tools') plus the catalog scope, subject areas, and filter dimensions. It explicitly contrasts with get_curriculum_dataset, so an agent can distinguish it from siblings without reading schemas.

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?

Gives explicit when-to-use conditions (need an interactive activity, visualizer, or game; filter by subject/grade/keyword/standard) and an explicit when-not-to-use with the named alternative for raw word lists. Nothing is left to inference.

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