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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds real behavioral context beyond that: it discloses that gate elements appear as names and outcomes only (a truncation/limitation) and where to get the fuller detail.

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?

Front-loaded with the core payload description, then the gate limitation and alternative. Dense enumeration of contents but each clause carries information; no filler sentences.

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?

No output schema exists, so the description must convey return contents, and it does so in detail (journey, dataset version, progress, job facts, approvals), plus the partial-coverage caveat for gates. Combined with read-only annotations, an agent has enough to call it correctly.

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 100%, with both projectId (from list_fine_tuning_projects) and customerId (superadmin only) documented in the schema itself. The description adds no additional parameter syntax or constraint, so the baseline of 3 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?

Clear verb (get) and resource (fine-tuning project), and the description specifies the composite contents returned: the eight-step journey, bound dataset version, review progress, training-job facts, and approvals. It differentiates from get_gate_result for the gate portion, but does not distinguish itself from siblings like get_training_job or list_fine_tuning_projects.

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?

It explicitly routes the agent to an alternative: 'use get_gate_result for one verdict element by element.' That is a concrete when-to-use-another-tool instruction. It lacks guidance on when to prefer this over other project-scoped getters, so not complete.

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