Play a word search

play_word_search
Read-onlyIdempotent

Creates a ready-made word search puzzle for a theme and level, drawn from the 11 themed word pools (Christmas, Halloween, Thanksgiving, Fall, Winter, Bible, Animal, Math, Science, 4th of July and Kids), at an easy, medium or hard level. Gives the letter grid, the words to find with their positions, the directions used, the seed and a link that opens the same puzzle on WordsDesk to print or save as a PDF. The widget is playable.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {
      "theme": "<theme>"
    },
    "name": "play_word_search"
  }
}

Input Schema

NameRequiredDescriptionDefault
seedNoLetters, digits, - or _ that pick the puzzle. The same theme, level and seed always give the same puzzle as the website. Without a seed the puzzle is the first one the website shows for that theme and level.
levelNoDifficulty: easy (10×10 grid, 10 words, across and down), medium (13×13, 15 words, adds diagonals) or hard (16×16, 20 words, all 8 directions). Kids has one level, easy. Default medium.
themeYesTheme of the word pool: christmas, halloween, thanksgiving, fall, winter, bible, animal, math, science, 4th-of-july or kids.

A3.8/5.0
Behavior4/5

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

Annotations already cover safety (readOnlyHint, idempotent, non-destructive), and the description adds real value beyond them: the exact return payload (grid, word positions, directions, seed, shareable link), the widget being playable, and the determinism rule tying seed+theme+level to the website's puzzle. It omits nothing critical for a read-only generator, though it doesn't discuss limits or failure modes.

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?

Front-loaded with the action and outcome, and the return-value sentence is informative. It spends some space re-enumerating all 11 theme names that the enum already lists, which is mild redundancy but not damaging.

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 three-parameter, fully documented read-only tool with an output schema, this description is more than sufficient — it conveys what the puzzle contains, the reproducibility rule, and that the result is playable and printable. An agent needs nothing further to call 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 explains theme, level and seed, including the level grid dimensions and the seed determinism. The description mainly restates the theme list rather than adding semantics not already in the schema, so baseline 3 applies.

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?

States a specific verb and resource ('Creates a ready-made word search puzzle for a theme and level') and scopes the source to the 11 themed word pools. The word 'ready-made' implicitly separates it from a custom-puzzle builder, but it never names make_word_search, so sibling differentiation is left to inference.

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

Usage Guidelines3/5

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

Usage is only implied: pick a theme from the pools and optionally a level/seed. There is no explicit statement of when to reach for this tool instead of make_word_search, list_themes or theme_words, and no note about what to do if a theme isn't recognized.

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