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

The description carries the behavioral load that annotations only hint at: it discloses that reads are bounded and paginated, that a `notice` in storage requires telling the person and refraining from deletion, that onItsOwn auto-approves certain task_propose calls, that `unread` is relative to 'your last acknowledged change', and that WORKSPACE_DELETED / WORKSPACE_BUSY are distinct failure modes. It never explicitly reconciles readOnlyHint=false (that the call advances your read position), though 'your last acknowledged change' implies it.

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?

No — see justification below; scoring 3.

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?

An output schema exists, yet the description still walks the payload in reading order, which is legitimately useful for an aggregate tool where section ordering is part of the contract. Error semantics and the pagination contract are covered; the only real gap is the undocumented cursor-to-section mapping.

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 33%: only workspaceId and why are documented, while taskCursor, activityCursor, handoffOffset and artifactOffset are bare. The description compensates partially by saying 'call it again with the continuation offsets and cursors for more', but it never maps which cursor resumes which section, leaving the agent to guess that taskCursor belongs to open tasks and activityCursor to recent changes.

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 ('Load bounded workspace context') and defines scope precisely: an aggregate snapshot read in order, not a single-resource read. It names task_list as the alternative for the tail of `waiting`, but never distinguishes itself from close siblings such as workspace_show, workspace_view_context or workspace_changes, so an agent must infer which aggregate view it wants.

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 concrete operating instructions: 'Read it in order', 'Call it again with the continuation offsets and cursors for more', and 'task_list reads the rest of waiting (assignee=me, reviewer=me)' — an explicit hand-off to a sibling. It also states the retry policy for WORKSPACE_BUSY ('nothing was changed, so retry the same call after a short wait'). What is missing is any statement of when NOT to use this tool, e.g. versus workspace_show or workspace_changes.

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