get_evidence_packet

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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the packet is "deterministic" and tied to the "latest" scorecard (a current-snapshot rather than historical read), but says nothing about permissions, size, cost, or whether the packet is cached/stable across calls.

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, and the three packet contents are listed compactly after the colon. Dense but every clause carries information; it reads as a noun phrase rather than an instruction, which is a minor structural weakness.

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?

No output schema exists, so the description must convey the return value, and it does list the packet's components reasonably well. However, it omits any guidance on invocation context or what the agent should do with the packet, leaving gaps for a tool whose output it must describe.

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 100% and the single parameter is documented with a concrete example ('unitrans'), so the schema already does the work. The description adds only the implicit scoping of 'one agency' and 'latest', which the schema does not restate.

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?

The description names a specific artifact and enumerates its three components (producer contract, work items with acceptance tests, feed identity), so an agent can tell it apart from get_scorecard or explain_finding. It never states a verb like "return" and does not explicitly contrast itself with those siblings, so it stops short of a 5.

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 guidance and no named alternative among the eight siblings. The phrase "one agency's latest scorecard" hints that it is scoped to the current scorecard snapshot, but the agent is left to infer when this is preferable to get_scorecard, explain_finding, or coverage_for.

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