tvx_set_timeframe

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

No annotations are present. The description only states the action without disclosing behavioral traits like side effects, required chart state, or data loading implications. For a mutation tool, this lack of transparency is a significant gap.

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?

The description is a single sentence with no waste. It is appropriately concise for a simple tool. However, it lacks structure (e.g., separate sections) and could include brief usage hints without compromising conciseness.

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?

Given the tool's simplicity (one required parameter, no output schema), the description is minimally adequate. However, it omits behavioral context and usage guidelines that would help an agent use it correctly in dynamic scenarios.

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?

The input schema has 100% coverage with a clear parameter 'timeframe' and example values ('1, 5, 15, 1D'). The description adds no extra meaning beyond the schema, so it meets the baseline of 3 without adding value.

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 'Set TradingView chart timeframe' clearly states the verb (Set) and resource (TradingView chart timeframe). It is specific and easily understood. However, it does not differentiate from sibling tools like tvx_chart_state, which might also modify chart settings, leaving a minor ambiguity.

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 provided on when to use this tool versus alternatives such as tvx_chart_state or tvx_set_symbol. There is no mention of prerequisites, typical use cases, or exclusions, leaving the agent without context for selection.

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