load_design_spec

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

With no annotations provided, the description carries the full burden. It discloses the return structure (design_spec_dir, slide_count, slide_files) and implies a read operation (load/retrieve). However, it does not mention error handling or side-effects, but the core behavior is transparent.

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 concise, with two short paragraphs plus args/returns. It is well-structured, though the return section is slightly redundant. Overall, no wasted words.

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 output schema exists, the description provides adequate context: what the tool does, what it returns, and a hint about downstream usage. It could be more complete by clarifying its place in the workflow (e.g., after finalize_design_spec), but it is mostly sufficient.

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 schema description coverage is 0%, so the description must add meaning to the parameter. It only repeats 'Project ID' and uses it in an example without elaborating on format or constraints. This adds minimal value beyond the schema.

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 clearly states the verb ('Loads'/'Retrieves'), the resource ('design spec'), and the scope ('from the project directory'). It distinguishes from sibling tools like load_outline and export_html/pptx by specifying it retrieves a previously generated PptxSlideSpec JSON.

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 hints at usage by mentioning project_id can be passed to export tools, but it does not explicitly state when to use this tool versus alternatives, nor does it provide when-not-to-use or prerequisites. The guidance is implicit and could be improved.

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