pwndbg_vis_heap_chunks

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

No annotations exist, so the description must convey all behavioral traits. It explains the output is a colorful visual map with color-coded regions for chunk boundaries, headers, and data, and notes the optional addr parameter. However, it does not mention what happens with invalid addresses, performance implications, or the return format (e.g., image or text). This is adequate but not comprehensive.

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 front-loaded with the key action, but includes extra metadata like source file, category, and a URL. While not extremely verbose, these details do not directly aid tool selection or invocation and could be trimmed. The structure is logical but not optimally concise.

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?

The tool has a simple interface (2 params) and an output schema, but the description fails to explain the output format or how to interpret the visual map. It does not mention prerequisites (e.g., active debugging session with heap) or error handling. Novice users would need additional context to use it effectively.

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 input schema has 0% description coverage, but the description provides a short explanation for each parameter: session_id as 'The UUID of the session' and addr as 'Optional starting address.' This adds basic meaning beyond the schema's title fields. However, the descriptions are minimal and do not elaborate on expected formats, defaults, or behavior. Baseline 3 is appropriate given the partial compensation.

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 first sentence clearly states the tool visualizes heap chunks graphically. The description adds distinctiveness by calling it 'one of pwndbg's most distinctive features for heap analysis' and contrasts with other heap tools through the visual aspect. It specifies the resource (heap chunks) and action (visualize/renders).

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 mentions it is for heap analysis but does not provide explicit guidance on when to use this tool versus siblings like pwndbg_heap, pwndbg_malloc_chunk, or pwndbg_tcache. No when-not-to-use or alternative tools are mentioned. The statement 'One of pwndbg's most distinctive features' implies it is a go-to for heap visualization but lacks specificity.

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