ppsspp_get_registers

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

With no annotations, the description fully discloses behavior: no side effects, pure read, and notes that the snapshot timing depends on emulation state (paused vs running). No contradictions with annotations as none are provided.

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 well-structured with labeled sections (PURPOSE, USAGE, BEHAVIOR, RETURNS) and every sentence adds unique value. It is slightly verbose but balanced given the need to cover multiple aspects for a tool with no annotations.

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 tool with no parameters and no output schema, the description fully covers purpose, usage guidance, behavioral transparency, and return format. It is complete and leaves no significant gaps for an AI agent to understand invocation and expected output.

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 no parameters, so baseline is 4. The description adds value by explaining the return format (multi-line with grouped registers), which is relevant for understanding the output even though it is not parameter documentation.

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 reads all MIPS Allegrex CPU registers, specifying GPR, FPU, and special registers. It uses a specific verb+resource and distinguishes from sibling memory-reading tools like ppsspp_read32 and ppsspp_read_range.

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 provides explicit usage contexts such as reverse engineering and debugging, including calling convention details for argument inspection. It offers clear guidance but does not explicitly state when not to use it or list alternative sibling tools for similar tasks.

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