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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds real value beyond that by disclosing the return shape: cells addressed by phaseId/workstreamId, human-readable labels, ordered card lists with cardIds, and documents not on any cell. No pagination or size limits mentioned, keeping it below 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?

Two sentences, both dense but front-loaded with the purpose before the return shape and the follow-up routing. No filler, though the second sentence is long and carries multiple clauses that could be split for scanability.

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 description carries the burden of explaining return values and does so thoroughly — board variant, cell address fields, label format, card ordering, and orphan documents. It omits any note on board size or truncation, which is the only meaningful gap for a whole-board read.

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?

Only one parameter and schema description coverage is 100%, so the schema already documents projectId including its source (traceable_workspace_projects). The description adds nothing parameter-specific beyond 'a project's board'. Baseline 3 is appropriate.

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 a project's board') and immediately disambiguates the two variants: the Design Phases board for product/process projects versus the quality system diagram for Quality projects. An agent can tell this apart from traceable_grid_cell, traceable_workspace_map and traceable_doc_read from the description alone.

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 routes the agent: take a cell's phaseId/workstreamId and pass it as 'placement' to traceable_doc_create, traceable_doc_update_meta, or traceable_board_placeholder_create. That is concrete downstream guidance with named alternatives. It stops short of stating when NOT to use this versus other read tools, so not a full 5.

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