pio_debug_list

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

No annotations are present, so the description must carry the behavioral disclosure burden. 'List' clearly implies a read-only, non-mutating operation, and the description tells what fields are returned, but it does not clarify project scope, side effects, network interactions, or failure behavior.

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 a single front-loaded sentence with no filler. Every phrase contributes meaning: 'List', 'open debug sessions', and the specific output fields.

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?

For a zero-parameter list tool with an output schema available, the description is mostly complete because it states the main returned fields. It could add context about scope (e.g., current project vs. all projects) and behavior when no debug sessions are open, but these are minor for invocation.

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 tool has zero parameters and the input schema is empty, so the baseline for no-parameter tools is 4. No parameter documentation is needed, and the description correctly avoids inventing any.

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 uses a specific verb ('List') and a clear resource ('open debug sessions'), and it names distinguishing output details such as env, debug tool, running/halted state, and last stop frame. This makes it easy to tell apart from sibling action tools like pio_debug_start, pio_debug_cmd, and pio_debug_stop.

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 gives no explicit guidance on when to use this tool versus alternatives such as pio_monitor_list or pio_debug_start. There is no mention of exclusions, prerequisites, or preferred use cases beyond the basic implication of the verb 'List'.

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