pine_save

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

Annotations are absent, so the description must carry the full burden of behavioral disclosure. It only states the action and keyboard shortcut, but does not disclose whether this overwrites unsaved changes, whether it requires an open editor, whether it reports success/failure, or what side effects occur.

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 well-formed sentence that is front-loaded with the verb and resource, plus a helpful keyboard-shortcut hint. There is no wasted wording or redundant restatement.

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 zero-parameter save action, the description is minimally viable, but it leaves out context such as what 'current' refers to (active tab/editor), whether the operation persists to disk or workspace, and what happens if there is nothing to save. Given the absence of annotations and output schema, a bit more context would be warranted.

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 tool has zero parameters, so the baseline is 4. The description adds no parameter detail, but none is needed since the input schema is empty and coverage is 100%.

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 names a specific action ('Save') and a specific resource ('the current Pine Script'), which distinguishes it clearly from sibling tools like pine_get_source and pine_compile. The parenthetical '(Ctrl+S)' reinforces the exact operation without 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?

The description does not state when to use this tool versus alternatives such as pine_new, pine_open, or pine_set_source. There is no mention of prerequisites like having an editor open or whether this persists to a specific location, so the agent gets no routing guidance beyond the inferred action.

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