cliprogress_add_spinners

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

With no annotations provided, the description carries the full burden of behavioral disclosure, yet 'Add loading spinners' reveals nothing about side effects, which files get modified, reversibility, idempotency, or whether the directory must already contain a progress display. It is behaviorally silent, though not contradictory.

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?

Three words means zero waste, but this is under-specification rather than genuine conciseness. The description lacks the structure needed to convey target, prerequisites, or effect, and is not appropriately sized for a tool with an undocumented parameter and no annotations.

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 tool with no annotations, no output schema, and one fully undocumented parameter, the description is far too thin. An agent is left without knowledge of what api_key is for, what the tool modifies or returns, and how it compares with sibling progress-display tools.

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 exactly 50%: directory has a schema description but api_key has none. The tool description adds no meaning for either parameter, leaving api_key entirely unexplained and failing to connect directory to where the spinners are applied.

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 'Add loading spinners' is a near-verbatim restatement of the tool name cliprogress_add_spinners, adding only the modifier 'loading'. It states a verb and resource but fails to specify the target (a CLI project?) or the intended result, so it barely clears the tautology bar.

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?

No guidance is given on when to use this tool versus its close siblings cliprogress_generate_bars, cliprogress_add_multibar, or batch_add_progress. An agent has no basis for choosing spinners over bars or multibar displays for a given CLI project.

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