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

Annotations already establish readOnlyHint=false and destructiveHint=false, and the description is consistent with both. The description adds that logged items are inherited by future teammates, implying persistence, but it does not disclose side effects like deduplication, overwriting, or whether the record is editable later.

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 two tight sentences with no wasted words. The core 'what to record' is front-loaded, and the use case is stated immediately.

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 8 parameters, no output schema, and low parameter-level schema coverage, the description gives strong purpose and usage context but not enough operational detail to confidently populate optional fields or understand how this relates to update_project_decision and memory_save. It is functional but leaves gaps.

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 only 25%, so the description must compensate, but it adds little param-level meaning. It does clarify the semantics of 'kind' by naming the four categories, yet leaves 'client', 'client_id', 'project_id', 'detail', and 'task_id' without explanatory guidance beyond the sparse schema text.

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 states a specific action ('Record') and names the exact resource: things future teammates must inherit, enumerating decision, learning, preference, and constraint. It is clear enough to distinguish from log_project_event and log_project_issue even though it does not explicitly name them.

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 gives a direct and useful usage rule: use this whenever you make a judgement call that a later agent would otherwise re-litigate. It does not list exclusions or directly compare with sibling tools like memory_save or update_project_decision, but the when-to-use guidance is concrete and actionable.

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