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

Annotations already establish readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds genuinely non-structured context: the read is shared with every project member, which is a visibility/permission disclosure an agent needs before surfacing sensitive content. It omits any sizing or result-limit behavior, which keeps it below a 5.

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-loaded with what is returned, then routing, then privacy scoping — a sensible order with little waste. The closing sentence about a bare 'add a task' belonging to another app is the longest and least tied to a read tool, slightly diluting focus but still actionable.

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?

No output schema exists, and the description compensates by enumerating the returned sections (charter, roster, state counts, what needs the user), which is the right use of prose here. Combined with annotations the definition is nearly self-sufficient; only result size/edge-case behavior is unaddressed.

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?

With a single parameter at 100% schema coverage, the schema already says it accepts 'the project's name or its project_id'. The description adds no disambiguation guidance (e.g., what happens on ambiguous or partial name matches), so it sits at the baseline for schema-covered parameters.

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 and resource ('Read one RelayLink project's charter, roster and standing') and enumerates the concrete fields returned: outcome, definition of done, state, target date, roster with roles, work counts, and pending items. It also explicitly differentiates siblings, noting that project_work_find and project_brief 'go deeper', so an agent can route without opening schemas.

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 explicit alternatives (project_brief and project_work_find for depth, notebook_* for the user's private material) and a scoping rule: use only for work the user means to be visible to everyone on the project. It even covers the ambiguous-intent case, instructing the agent to ask once when a bare 'add a task' could target another connected app.

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