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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so safety is covered; the description adds useful context by itemizing exactly what the aggregate bundle contains (handoff, attention counts, top tasks, activity). It does not state how many 'top' tasks are returned, whether the handoff may be absent, or any cost/latency of the aggregation.

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: the first sentence defines the payload, the second handles when to call. Slightly long and list-heavy, but every clause (handoff, attention snapshot, top tasks, activity) carries real information rather than restating the name.

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?

There is no output schema, and the description compensates by enumerating the return payload contents, including the attention snapshot sub-counts (blocked / overdue / due soon / unassigned / stale). For a one-parameter read tool this is complete enough to call and interpret correctly.

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?

Single required board_id with 100% schema description coverage, so the schema already documents the parameter. The description only echoes scope with 'for a board' and adds no format or sourcing guidance (e.g., where to obtain the board_id). Baseline 3 applies.

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+resource ('get the full project context for a board') and then enumerates the payload: latest session handoff, attention snapshot, top open tasks, recent activity. That enumeration distinguishes it from siblings like get_board_prompt, list_tasks, and get_digest without the agent needing to open any schema.

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 says to call it at the START of a session and gives concrete trigger utterances ('continue where we left off', 'what's the state of the project', 'resume our work'), plus the key condition of a NEW chat after a saved handoff. It names no alternative tool, but the trigger conditions are precise enough that routing is unambiguous.

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