pwndbg_linkmap

Reveal the dynamic linker's link map to examine loaded shared objects with their base addresses and file paths.

Instructions

Show the dynamic linker's link map (loaded shared objects).

pwndbg command: linkmap Source: pwndbg/commands/linkmap.py Category: Linux/libc/ELF

Displays the linked list of loaded shared objects maintained by the dynamic linker (ld.so), showing base addresses and file paths.

Args: session_id: The UUID of the session.

Behavior3/5

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

No annotations provided, so description carries full burden. It describes output (base addresses, file paths) but does not explicitly state it is read-only or disclose any side effects.

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?

Concise and well-structured with title, source, category, args, and a reference link. No wasted words.

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

Completeness4/5

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

Given the tool's simplicity and the presence of an output schema, the description covers the essential information. Could mention potential error conditions like invalid session_id.

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

Parameters2/5

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

Description adds 'UUID of the session' to the session_id parameter, but schema has 0% coverage, so more context about the session would be helpful. Barely adds value beyond schema.

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 it shows the dynamic linker's link map (loaded shared objects), listing base addresses and file paths. This distinguishes it from sibling tools like pwndbg_elfsections or pwndbg_plt.

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

Usage Guidelines3/5

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

Usage is implied by the category and description (for debugging shared object loading), but no explicit when-to-use or alternatives are provided.

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