log_creator_activity_batch

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

With no annotations, the description must carry the full behavioral burden. It does disclose that this is a write ('one spreadsheet write'), append-only, and batched into one round trip, which is useful context. However it omits error handling for partial batch failures, idempotency/duplicate behavior, and any permission requirements.

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?

Three tight sentences, front-loaded with the action and scope, followed by the efficiency rationale and the routing rule. No filler; every sentence earns its place.

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 one-parameter batch-append tool with no annotations or output schema, the description covers purpose, efficiency benefit, and cross-plan scope. It lacks any note on batch failure semantics or return behavior, but with no output schema that gap is minor.

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 single parameter has 100% schema description coverage, so the schema already documents every nested field. The description adds a small amount of meaning — that entries may span multiple plans, clarifying the planId-per-entry structure — but mostly rests on the schema baseline.

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 (Append) and resource (creator-mention rows) with explicit batch scope ('several ... at once'), and distinguishes itself from the singular sibling log_creator_activity. An agent can tell immediately what this does and how it differs from the single-entry version.

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?

Explicitly names the alternative ('Prefer this over repeated log_creator_activity calls') and the precise condition that selects it ('whenever you have more than one mention to record'). It also notes entries may span multiple plans, removing a likely source of hesitation.

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