Search Canvases

search_canvases

Search canvases with case-insensitive substring matching on node text, labels, file paths, URLs, IDs, and edge labels. Optionally limit to a single file.

Instructions

Case-insensitive substring search across stored canvases. Matches node text, labels, file paths, URLs, and IDs, plus edge labels. Searches every canvas in OUTPUT_PATH unless a filename is given.

Behavior4/5

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

With no annotations, the description carries full burden. It discloses case-insensitive behavior, target fields, and the global/default search scope (all canvases in OUTPUT_PATH unless filename specified). However, it does not describe the output format, though an output schema exists.

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?

Two concise sentences front-load the core action and key behaviors. No redundant or extraneous information.

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

Completeness4/5

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

The description covers search scope, fields, and the filename parameter. It does not mention match handling (e.g., what if no matches) or pagination, but the output schema likely covers return structure. Given two parameters and a common tool pattern, it is mostly complete.

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 0%, but the description explains the optional filename parameter (limits search to a single canvas). The required query parameter is implied by the search action but not explicitly described. This adds some value beyond the schema.

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 description clearly states the tool performs a case-insensitive substring search across stored canvases, specifying the fields matched (node text, labels, file paths, URLs, IDs, edge labels). It distinguishes this from siblings like list_canvases or read_canvas by emphasizing search across multiple fields and optional filename filtering.

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?

The description implies usage for content-based search but does not explicitly contrast with siblings (e.g., when to use list_canvases vs search_canvases). It provides guidance on the filename parameter to limit scope, but lacks 'when not to use' or alternative scenarios.

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