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

With no annotations and no output schema, the description carries the full disclosure burden and it partially does so by describing the return content (chips left, value, recommendation). However it says nothing about read-only behavior, side effects, or how the gameweeks horizon affects the advice. For a low-risk planning tool this is adequate but not rich.

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. It communicates the three outputs efficiently, though it is a sentence fragment rather than a structured statement of purpose.

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?

The description outlines the returned content well enough to substitute for the missing output schema, but with two undocumented parameters, no annotations, and no schema coverage, key invocation details (what team_id refers to, what gameweeks controls) are left unspecified.

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 description coverage is 0%, so the description must compensate, and it largely does not. Neither team_id nor gameweeks is mentioned; the phrase 'this half of the season' only loosely gestures at the lookahead horizon without clarifying the gameweeks parameter's role or default.

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 resource (chips) and enumerates the outputs: remaining chips, their worth, and a play/save recommendation. It clearly distinguishes itself from siblings like optimal_squad, pick_captain, and suggest_transfers, which handle squad and transfer decisions rather than chips. It stops short of naming a sibling it is not, but the intent is unambiguous.

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, when-not-to-use, or alternative guidance. The agent can infer this is chip-planning advice, but nothing states the conditions under which chip_advice is the right call versus consulting gameweek_status or team_summary. No prerequisites, timing, or dependency information is given.

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