pwndbg_arena

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

No annotations provided; description carries burden. It states the tool shows malloc_state structure fields, which implies a read operation. No side effects or safety info beyond that. Adequate but not exhaustive.

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?

Description is moderately sized but includes metadata lines (source, category) that are not essential. The core info is front-loaded. Could be more concise without the metadata.

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?

Output schema exists, so return value explanation is not required. However, the description lacks explanation for the required session_id parameter. With no annotations, the tool is moderately complete but has gaps.

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%. The description adds meaning for addr (optional, defaults to current arena) but does not explain the session_id parameter. With no schema descriptions, the description should compensate more.

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 prints the contents of a malloc arena, specifies the pwndbg command, source, and category. It distinguishes from siblings like pwndbg_arenas by focusing on a single arena.

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 default behavior (current thread's arena) and optional addr parameter but does not explicitly state when to use this tool vs alternatives like pwndbg_arenas. Usage context is implied but not clearly delineated.

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