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

Beyond the annotations (which already say idempotent, non-destructive, not read-only), it discloses that the undo path is receipted, that the underlying list is untouched on removal, that the call returns template_url, and that this is a 'write tier' operation. Consistent with destructiveHint=false.

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?

Two dense sentences with the mode split front-loaded and no filler. Parentheticals (endpoint, receipted, list untouched) are compressed but readable rather than wasteful.

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 two-parameter, no-output-schema mutation, the description covers both modes, side effects, reversibility, and the returned link. Only failure cases (missing list, already-shared state) are absent.

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 0%, so the description carries the burden and does: it defines the two values of `shared` by their effect and endpoint, and identifies `list_id` implicitly as the target list. It does not spell out the id format or error behavior for a non-shared list.

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 states a specific verb and resource — sharing a task list as a template and removing it — and disambiguates the two modes by the `shared` flag. It does not name sibling tools like tascan_apply_template or tascan_list_templates, so the boundary with those is left implicit.

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 gives an explicit condition for each mode: shared=true posts to /templates/:list_id, shared=false deletes the template entry. It does not say when to prefer this over applying an existing template or listing templates, so alternative selection remains inferred.

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