recap

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

No annotations are provided, so the description carries the full burden. It describes what recap does (summarize past events) but does not disclose whether it is read-only, destructive, or if it requires specific permissions. For a tool that likely queries state, this omission leaves the agent uncertain about safety.

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 extremely concise—one sentence plus a purpose note—with no extraneous information. Every word serves a clear purpose.

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?

Given the tool has no parameters and no output schema, the description fully explains its purpose (summary of past events) and when to use it (resuming in a fresh chat). It is complete for the complexity level.

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?

With zero parameters and 100% schema coverage, the description does not need to add parameter details. The baseline is 4 per guidelines, and the description adds no confusion.

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 'last loop's events, open wounds, who hates you now' indicating it provides a historical summary of the game loop, distinguishing it from siblings like 'get_state' which likely gives current state. The verb 'recap' is self-explanatory, and the context 'For resuming in a fresh chat' specifies its use.

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 line 'For resuming in a fresh chat' explicitly states when to use this tool: when starting a new chat to get context. It does not provide when-not-to-use or alternatives, but the guidance is clear for the intended scenario.

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