Content Batch Analyze

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

Annotations already declare readOnlyHint and openWorldHint, and the description goes beyond them by disclosing concrete limits: rejection over 5,000 discovery entry visits, compare payloads over DOC_MAX_DOWNLOAD_BYTES, and 3-way bounded concurrency in individual mode. These operational constraints are genuinely useful and not derivable from the annotations.

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?

Front-loads the core action, then constraints, then the two modes. Tight and readable with little waste, though the mid-sentence line break in the source text is a minor formatting blemish.

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 an output schema present, return values need no explanation, and the description covers the mode selection and payload limits for this 8-param tool. It is nearly complete, missing only sibling-tool disambiguation to be fully self-sufficient.

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 100%, so the schema already documents all 8 parameters, establishing a baseline of 3. The description reinforces mode semantics and adds the concurrency/limit context but supplies no syntax or format detail beyond what the schema provides.

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?

States a specific verb (analyze) and resource (multiple content files), with the batch scope made explicit via 'multiple content files from a directory or explicit file list'. This implicitly separates it from the single-file content_analyze sibling, though it never names that sibling or video_batch_analyze to fully disambiguate.

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?

Gives solid intra-tool guidance by explaining when to pick 'compare' (cross-document, single call) versus 'individual' (per-file, bounded concurrency). However it offers no guidance on when to use this tool versus alternatives like content_analyze or video_batch_analyze, so tool-level selection is left to inference.

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