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

With no annotations, the description carries full burden. It discloses output format and size constraints (max 4096 bytes), but doesn't mention error conditions, performance characteristics, or what happens with invalid addresses/sessions. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Extremely efficient structure: purpose statement, format details, size limit, then parameter documentation. Every sentence adds value with zero wasted words. Well front-loaded with core functionality.

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

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

For a memory inspection tool with no annotations or output schema, the description covers basic functionality and parameters adequately. However, it lacks information about return format details beyond 'standard format', error handling, and how it relates to other memory tools in the sibling list.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, but the description's 'Args' section fully documents all three parameters with clear semantics: session_id identifies the session, address is the start location, and size specifies bytes to dump with default and max values. This compensates well for the schema gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Formatted hex dump of memory' with specific format details. It distinguishes from siblings like read_memory by emphasizing the formatted output, but doesn't explicitly contrast with all memory-related tools.

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

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

The description implies usage for viewing formatted memory dumps, but doesn't explicitly state when to use this versus alternatives like read_memory or search_memory. No guidance on prerequisites or exclusions is provided.

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