Ffllistsessions

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

No annotations are provided, so the description carries the full burden. It usefully discloses the scope limitation to sessions started by this server, which prevents the agent assuming it sees all sessions, but it says nothing about whether terminated sessions appear, ordering, or limits. The output schema covers return values, lowering the bar somewhat.

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; every clause (active, ffl share, this server) earns its place by narrowing scope.

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 zero-parameter read with an output schema, the description gives enough to call it correctly and sets scope expectations. Only the lifecycle question (active vs. ended) and ordering/pagination remain unstated.

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?

The tool takes zero parameters and the description correctly presents it as unfiltered, so there is no parameter semantics to explain. Baseline 4 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?

States a specific verb and resource ("List active ffl share sessions") plus a scope qualifier ("started by this MCP server"). It does not explicitly contrast with the closely named siblings fflGetSession and fflGetSessionEvents, so an agent must infer the boundary.

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?

The word "active" narrows the use case implicitly, but there is no explicit when-to-use/when-not or named alternative for inspecting a single session or session history. Usage is inferable but not guided.

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