gdb_command

Execute any GDB command on a J-Link connected target and retrieve the output. For run commands, waits until target halts or timeout.

Instructions

Send any GDB command and get the response. For execution commands (continue, step, next, finish, until), blocks until the target stops or times out. If the target doesn't stop, use gdb_wait to poll. Examples: 'bt' (backtrace), 'info threads', 'print myVar', 'break main', 'continue', 'next', 'step', 'finish', 'info registers', 'x/10xw 0x20000000'

Behavior3/5

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

No annotations provided, so description carries full burden. Discloses blocking and timeout for execution commands, but does not mention side effects (e.g., setting breakpoints modifies state) or response format. Lacks full behavioral context.

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?

Description is concise with three sentences and examples, front-loaded with purpose. Every sentence adds necessary information without redundancy.

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

Completeness3/5

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

No output schema, so description should explain return value format, but only says 'get the response'. Missing details on error handling or response structure. Given moderate complexity and sibling count, description is adequate but not complete.

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

Parameters4/5

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

Schema covers both parameters with descriptions (100% coverage). Description adds value through examples of commands and clarifies timeout default, enhancing understanding beyond schema alone.

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?

The description clearly states the tool sends any GDB command and gets a response, with specific verb and resource. It distinguishes from siblings like gdb_wait by explaining blocking behavior and when to use the alternative.

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

Usage Guidelines5/5

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

Explicitly states when to use (any GDB command) and when not (for execution commands that block, with suggestion to use gdb_wait if target doesn't stop). This provides clear context and alternatives.

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