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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description adds genuinely new behavior: the two filter modes, the oldest-first ordering, and the exact set of fields returned (task_id, title, notes, status, assignee, due, updated_at) — valuable since there is no output schema. It omits pagination/limit behavior, which the schema only hints at.

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 core behavior is front-loaded in the first two clauses and every sentence carries content. The trailing '-- MakeHybrid API plan, GET /..., group asana' provenance is boilerplate but adds the endpoint identity, so it earns a marginal keep.

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 output schema, the field enumeration and ordering rule make the definition self-sufficient for a read-only list tool. The remaining gap is that 'since' appears from nowhere relative to the declared parameters, and pagination via cursor/limit is left entirely to the schema's example.

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 3 is the baseline, but the description is the only place the 'since' query parameter's meaning (milliseconds, updated-after filter) and its behavioral effect are documented. It does not say that 'since' must be placed inside the generic 'query' object, which is a real gap given the schema exposes no such property.

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 verb+resource ('The tasks in one project') along with the exact REST endpoint path, so the agent knows precisely what it fetches. It does not explicitly distinguish itself from siblings such as complete_asana_v1_connections_projects or the ClickUp/Jira task equivalents, leaving that inference to the tool name.

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?

It gives a clear conditional usage rule: no 'since' returns unfinished tasks, with 'since' (milliseconds) returns tasks Asana changed after that point, oldest first. That is strong contextual guidance, but there is no guidance on when to pick this over the sibling project-level or other-provider list tools.

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