edb_analyze_region

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds beyond that by explaining the tool is equivalent to EDB's Analyzer, shows control flow information, and returns analysis with counts. It also specifies the address format and default size.

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?

The description is concise, with key information front-loaded. Each sentence serves a purpose: tool action, equivalence, control flow info, then Args and Returns. No fluff.

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?

Given the annotations and presence of an output schema, the description covers the main purpose, parameters, and return type. It lacks error handling details or edge cases, but for a read-only analysis tool, it is sufficiently complete.

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?

The description lists parameters with types and defaults, but the input schema already contains descriptions for address and size. The description adds the return value type. Schema description coverage is effectively non-zero due to schema's own descriptions, so baseline 3 applies.

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 analyzes a code region for call instructions, branch instructions, and strings, equivalent to EDB's Analyzer plugin. It distinguishes from siblings like edb_analyze_basic_blocks and edb_analyze_calls_at by focusing on region-level analysis for specific instruction types.

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 analyzing code regions to get instruction counts and control flow, but does not explicitly state when to use this tool versus alternatives like edb_analyze_calls_at or edb_analyze_basic_blocks. No when-not guidance provided.

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