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

There are no annotations, so the description carries the full burden. "Redo" implies a state mutation, but nothing is said about permissions, side effects on downstream steps, whether progress is reset, or idempotency. The alias claim to jump_to_step is behavioral information but is left unexplained.

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?

One short sentence with no wasted words and the core action front-loaded. However, the brevity is achieved through under-specification rather than economy — the alias parenthetical occupies half the text while the actual semantics go unexplained.

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?

A mutation tool with no annotations, no output schema, and two undocumented required parameters needs substantially more description than one line. An agent cannot determine prerequisites, resulting state, or how this differs from jump_to_step without trial and error.

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?

Three parameters with only 33% schema description coverage: objectiveId and captureJobId are bare strings documented nowhere, and the description contributes no meaning about what an objective ID vs. capture job ID scopes. Only notification_message has schema text, and the description adds nothing to it.

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?

"Redo a done step" names an action on a step, but the tool is called redo_objective, so the step/objective relationship is unclear. The parenthetical "alias jump_to_step" adds a routing hint but also raises ambiguity: it is not stated whether this is literally the same operation as the sibling jump_to_step or a wrapper around it.

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 statement of when to use this versus jump_to_step, complete_step, mark_objective_done, or select_capture_step — all plausible siblings for re-doing or moving through steps. The alias note implies interchangeability but gives no selection criteria or preconditions (e.g., must the step already be done?).

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