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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description is not burdened with safety disclosure. It adds the 'bounded' trait and lists content types, but does not describe pagination defaults, mode behavior, or other operational details beyond what the schema already provides.

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 entire description is a single, compact sentence that front-loads the core action ('Read bounded project context') and then efficiently enumerates the major content categories. No redundant words or filler.

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 high parameter count (11) and the presence of a full output schema, the description provides a sufficient high-level overview without needing to explain return values or parameter syntax. It could have mentioned the default mode or the purpose of the 'mode' parameter, but that is covered in the schema, so the description remains adequately complete.

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 the baseline is 3. The description itself does not add parameter-specific meaning; it only states what content is included. All 11 parameters are fully documented in the schema, so no compensation is needed.

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 uses a specific verb ('Read') and identifies the exact resource ('bounded project context for editing') with a clear list of included content (timeline items, media assets, transcripts, captions, and stable IDs). This clearly distinguishes it from sibling tools like projects_get or media_transcript_get by emphasizing the consolidated yet bounded nature.

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 implies usage during editing workflows by stating 'for editing', but it does not explicitly mention when to use this tool versus alternatives such as projects_get, media_assets_get, or media_transcript_get. There are no exclusions or explicit alternative references, leaving the decision to the agent.

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