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

With no annotations provided, the description usefully discloses that the call is read-only and free, and that results are ordered newest first. It stops short of describing pagination behavior around the limit parameter, retention window of 'recent' events, or auth/scope requirements for reading another SDR search's activity.

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 compact sentence that front-loads the resource and ordering before the analogy, with zero filler. Nothing here is wasted or repeated from structured fields.

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 two-parameter, no-output-schema feed tool the description covers the essentials — what it returns, ordering, and read-only/free semantics — but leaves the closest sibling (sdr_recent_signals) undifferentiated and says nothing about the limit parameter's effect, which an agent needs to call it well.

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 50%: limit has only 'Default 40' and search_id has no description at all. The description implies search_id scopes to 'one SDR search' but adds no format, source, or discovery hint for obtaining the ID, and says nothing about what limit controls or its bounds.

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 resource (discovery + outreach events for one SDR search) and a clear ordering (newest first), plus an analogy to the dashboard ticker that anchors what it returns. It does not, however, disambiguate itself from the sibling sdr_recent_signals, which an agent could easily confuse with an activity feed.

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 explicit guidance on when to call this versus sdr_recent_signals, sdr_outreach_summary, or sdr_run_states, all of which surface similar SDR activity. 'The same ticker the dashboard shows' implies a monitoring use case but leaves the routing decision to inference.

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