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

Annotations already declare readOnly, idempotent, non-destructive behavior, lowering the bar. The description adds useful context beyond them: the algorithm (PageRank), the edge type it runs over (TRANSFERS), the ordering (highest first), and that results carry bank ids. It does not cover scale limits or pagination.

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?

Dense and front-loaded: the core behavior leads, then graph values, then an implementation note. The trailing 'FalkorDB features: algo.pageRank' is marginal metadata but brief enough not to bloat the definition.

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 and only safety annotations, the description does convey the return shape (ranked accounts with bank ids). However it omits how top_k bounds results and what happens across the different graph scopes, leaving gaps for a 2-parameter analytical tool.

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 0%, so the description must compensate. It usefully enumerates valid graph values ('consortium', 'bank_<id>', 'case_<id>'), which the schema lacks, but leaves top_k unexplained beyond the implied 'highest first' ordering.

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 concrete resource and method: accounts ranked by PageRank over TRANSFERS, returned highest-first with bank ids. This clearly distinguishes it from siblings like connected_components, find_rings, and trace_money_path, though it never names a sibling explicitly.

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 or comparison against alternatives; the closest thing is the graph value enumeration, which is parameter help, not usage routing. The agent must infer that this is the money-pooling/centrality tool from the phrase 'where money pools'.

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