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

Annotations already declare read-only, idempotent, and non-destructive behavior. The description adds valuable behavioral context: each entry carries an item id for traceability, and it warns 'Quote; do not invent outcomes the threads do not state.' It also briefly describes the return shape. These additions go beyond the annotations and aid correct use.

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 dense but well-structured paragraph, front-loading the overall purpose and then detailing content and a caution. Every sentence contributes: purpose, content delineation, traceability, and usage guidance. It could be slightly more concise, but it avoids fluff.

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?

Without an output schema, the description does a thorough job explaining what is returned: the shape of work, resolved threads with outcomes, deferred items with reasons, open items, and quoted conversations. It also mentions traceability and a quoting rule. Minor gaps (e.g., pagination behavior) are covered by the input schema's offset parameter, making this nearly complete.

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 coverage is 100%, so parameter meanings are fully defined there. The description reinforces the section-based content (resolved, deferred, open, discussions) but does not add syntax or format details beyond what the schema already provides. Baseline 3 is appropriate when schema does the heavy lifting.

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 the tool provides a complete package for writing a project review or hand-off, enumerating the included sections. It names the resource (project review) and the value (accurate, traceable). However, it does not explicitly differentiate from siblings like decision_log or get_item, leaving a small gap.

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?

Usage is implied by 'Everything needed to write an accurate project review or hand-off document,' but there is no explicit guidance on when to choose this tool over alternatives or any exclusions. The schema's section enum provides some direction on how to use parameters, but the description itself is vague about when to use this tool.

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