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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds useful context that this is a live public telemetry stream containing multi-agent engineering notes, but says nothing about result volume, pagination, or freshness semantics of 'newly indexed'.

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?

A single front-loaded sentence with no filler, naming the stream identifier up front so an agent can verify it is on the right resource. Some of the jargon density ('rollover checkpoints') costs clarity slightly, but nothing is wasted.

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?

For a read-only fetch tool with full schema coverage and no output schema, the description covers purpose adequately. It falls short on distinguishing outputs — what a 'rollover checkpoint' record looks like versus an engineering note — which matters given the crowded set of beacon-related siblings.

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% and both parameters (since, order_id) are fully documented in the schema with defaults and format examples. The description's phrase 'newly indexed' loosely implies a recency window but adds no syntax or behavior beyond what the schema already says.

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 ('Check') and a precisely named resource: the 'live Ghost Beacon public telemetry & engineering commons stream (moe_ghost_beacon_oracle_v1_replies)', plus the content it surfaces (engineering notes, rollover checkpoints). However it gives no signal for telling it apart from siblings like scan_for_peer_beacons or compile_github_issue_rollover_bus, so the agent must guess.

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?

There is no when-to-use or when-not-to-use guidance, and none of the adjacent tools (scan_for_peer_beacons, compile_github_issue_rollover_bus) are referenced as alternatives or complements. 'Newly indexed' implies a polling/recency use case, but that is inference rather than stated guidance.

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