Sync Presentation Deck to Canva Cloud

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered; the description's added value is telling the agent what comes back (page-count comparison, edit link, Present Mode link). But the word 'đồng bộ' (sync) in the name and description sits awkwardly against a read-only hint, and the description never clarifies whether any state is written or what happens when page counts mismatch, leaving genuine ambiguity for a tool whose name implies mutation.

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 dense sentence that front-loads the action and then lists the three concrete returns, with no filler. It is compact for the amount of information conveyed, though the run-on list format slightly blurs which items are outputs versus inputs.

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?

With no output schema, the description usefully compensates by spelling out the return payload (page count comparison, edit link, Present Mode link), which is the key thing an agent needs. What it omits is edge-case behaviour — a page-count mismatch, an unmet default design_id, or failure modes on an open-world target.

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%, so both parameters (design_id with its default deck, presentation_path as the local .pptx to compare) are already documented in structured form. The description adds no syntax, format, or default behaviour beyond that, so the baseline 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?

The description names a specific verb pair (check/sync), a specific resource (the presentation deck vs. Canva Cloud), and enumerates the concrete outputs: page-count reconciliation plus edit and Present Mode links. It does not, however, distinguish itself from near-neighbours like canva_get_design_info or canva_export_presentation_deck, which an agent could plausibly confuse it with.

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?

Usage is only implied: the presence of 'presentation_path' (a locally edited .pptx) suggests this is called after local edits to reconcile against the cloud copy and hand the user a presentation link. There is no explicit when-to-use statement and no named alternative telling the agent to prefer canva_get_design_info for plain metadata or canva_export_presentation_deck for file export.

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