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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so safety and determinism are covered. The description adds that the content includes links to key public pages, which is mild extra context, but says nothing about output shape or length beyond the topic list.

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 enumerating the content scope, with no filler. The comma-heavy topic list is dense but each clause maps to real content coverage.

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, and the description compensates by enumerating what the result contains (product identity, audience, tracked data, plans, bank data/contracts, links). For a static no-param info tool this is largely sufficient, with only minor gaps about depth or formatting.

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?

Zero parameters, so the baseline of 4 applies. The description correctly implies no inputs are needed by framing the tool as a fixed informational resource.

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 the specific subject matter (what FundingTracker.app is, who it's for, what it tracks, plans, bank data and contracts handling, links to public pages). This is clearly distinguishable from the calculator/lookup siblings, though it never explicitly contrasts itself with them.

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?

Usage is only implied: an agent can infer this is the orientation/overview entry point, but there is no explicit 'use this when' or 'use X instead' statement. The sibling list makes the alternative route (calculate_mca_apr, search_funders) obvious but the description doesn't say so.

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