Closed trades (journal)

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds content semantics (round trips, net P/L, holding period) but says nothing about timezone handling, pagination behavior, or how period interacts with from/to beyond what the schema states.

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 dense fragment that front-loads the resource and enumerates its fields with zero filler. Nothing could be removed without losing information.

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 field enumeration partially compensates by describing the return payload. However, a 7-parameter read tool with preset ranges and pagination would benefit from guidance on combining period with from/to and on default market scope, none of which is present.

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 71%, with the from/to/period/market/symbol params well documented in the schema itself, while page/limit are undocumented but self-evident given defaults and bounds. The description contributes no filtering syntax or edge-case detail (e.g. period vs from/to mutual exclusion), so it neither compensates for the gap nor adds meaning beyond the schema.

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 resource (a trading journal of round trips) and enumerates the payload fields (entry/exit dates and prices, volume, net P/L, holding period), so an agent knows exactly what it returns. It stops short of an explicit verb and does not contrast itself with the closely related siblings get_recent_trades or get_realized_returns, which would be needed for 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 guidance on when to call this tool versus the many sibling reads such as get_recent_trades, get_realized_returns or get_sell_journal. Prerequisites, scope (e.g. whether it covers all markets by default), and exclusions are entirely absent.

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