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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds useful non-annotation context by naming the three data sources it aggregates (dev-fund PRs, ecosystem projects, status transitions), which tells the agent what dimensions of 'tracking' come back. It does not mention freshness, rate limits, or behavior when no code links exist.

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?

Three compact sentences, front-loaded with the action and the payload, then the usage note. 'Canton governance.' is a fragment that adds domain scoping but is slightly terse; nothing is wasted overall.

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?

With no output schema, the description carries the burden of saying what comes back, and it does list the three evidence categories. Combined with annotations covering the safety profile and a fully documented single parameter, an agent has enough to invoke and interpret it; only return-format details (e.g. links, counts, status vocabulary) are absent.

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?

There is a single required parameter with 100% schema description coverage, including accepted ID formats ('0112', 'CIP-0112', 'PR-0088'). The description adds nothing about the identifier beyond what the schema already documents, so 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?

The description states a specific verb and resource: report whether code/grants are tracking a given CIP, enumerating the evidence types (dev-fund PRs, ecosystem projects, status transitions). That is far more than a restatement of the name. It stops short of explicitly differentiating itself from near-neighbors like get_cip_history or get_cip, leaving that inference to the agent.

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?

It gives explicit sequencing advice: 'Use after find_cip_for_feature to gauge readiness,' which tells the agent both the preceding call and the decision context. There is no statement of when not to use it or which sibling to prefer for adjacent questions, so it falls short of a full 5.

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