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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering safety. The description adds that the session is 'isolated' and 'revisioned', which are behavioral details not in annotations. It does not contradict annotations and provides useful context about session semantics.

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 a single sentence with no redundant phrases. It front-loads the core action and location, and every word earns its place.

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 simple open operation with two parameters and no output schema, the description covers the essential context: where the file comes from (ICCPLUS_WORKSPACE) and the nature of the session (isolated, revisioned). The normalize parameter is documented in the schema, so nothing critical is missing for the agent to invoke correctly.

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 50% – only normalize has a description. The description implies path is a JSON file path (from ICCPLUS_WORKSPACE), which adds some meaning beyond the bare 'path' parameter. However, it doesn't elaborate on normalize, and the description does not fully compensate for the missing path description, though it partially does.

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 ('open') and resource ('project JSON file from ICCPLUS_WORKSPACE'), and states the outcome ('into an isolated revisioned session'). This clearly distinguishes it from siblings like read_project (which likely just reads) and create_project (which creates new projects).

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 provides context (workspace location, isolated revisioned session) but does not explicitly compare to alternatives or state when not to use it. Given the sibling list includes read_project, save_project, and close_project, an agent can infer usage, but there is no direct guidance on choosing this over others.

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