local_summarize_and_extract

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states a high-level compression goal and does not disclose whether content stays local, how model selection works, how chunking or size limits behave, or what the extraction_goal drives. This is under-disclosed for a data-processing tool.

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, and the content-type list plus 'before cloud reasoning' are both useful context. It is concise, though perhaps lean for a tool with this much schema ambiguity.

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?

With no annotations, 0% schema coverage, and three parameters, the description needed to provide far more operational and parameter context. It gives only a purpose sentence, leaving sibling selection, parameter semantics, and processing behavior essentially uncovered; the output schema only relieves return-value documentation.

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?

Schema description coverage is 0%, so the description must compensate for the three parameters. It only implies that content holds large files/logs/traces/documentation; it does not explain extraction_goal or model, and their required semantics are left to inference.

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 names a concrete verb ('compress') and target resources ('massive files, logs, terminal traces, or documentation') and identifies the output as 'high-density summaries'. However, it omits the extraction half implied by the tool name and the required extraction_goal, and it does not distinguish the tool from local_chunked_summary or local_extract_json.

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 phrase 'before cloud reasoning' gives implied context for when to use this tool as a local preprocessing step. But it gives no explicit guidance on when to prefer this over siblings like local_extract_json or local_chunked_summary, and no exclusions or prerequisites are mentioned.

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