read_resource

Read-only

Retrieve resource content by providing its URI. For templated resources, fill in parameters; returns text or base64-encoded binary data.

Instructions

Read a resource by its URI.

For static resources, provide the exact URI. For templated resources, provide the URI with template parameters filled in.

Returns the resource content as a string. Binary content is base64-encoded.

Tool call template

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

TDQS

A4.7/5.0
Behavior5/5

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

The readOnlyHint annotation is consistent with the described read-only behavior. The description adds useful details about return content and base64 encoding, going beyond the annotation without contradicting it.

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?

The description is compact and well-structured, with no unnecessary words or repetition. It delivers all essential information in two sentences.

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 simple read operation, the description is complete: it covers input format, output type, and encoding. No further details are needed for correct usage.

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?

The single parameter 'uri' is described in the schema, but the tool description adds important nuance about static vs. templated URIs, which is not present in the schema. This additional guidance improves parameter understanding.

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?

Clearly states the verb 'Read' and the object 'resource by its URI.' It distinguishes from sibling tools such as list_resources (listing) and legal_* tools (specific legal actions) by focusing on reading a single resource.

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?

Provides guidance on static vs. templated URIs and explains output encoding. Does not explicitly contrast with alternatives, but the purpose is straightforward and the instructions are sufficient for correct invocation.

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