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

Annotations already declare destructive=true, idempotent=true and openWorld=false, so the safety profile is covered structurally. The description adds genuinely new behavioral context by naming the authorization requirement and the concrete INSUFFICIENT_ROLE failure mode with required_roles, which the annotations do not convey.

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 sentences, front-loaded with the purpose and field list, then the role constraint. No filler, though the parenthetical field list is slightly dense and unevenly complete.

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 destructive, nested-object mutation with no output schema, the description covers purpose and auth but leaves gaps: idempotency_key semantics, patch merge/patch-vs-replace behavior, and two patch subfields remain unexplained.

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 0%, so the description must carry parameter meaning. It names five updatable fields (name, website, industry, audience, writing language) but omits sub_industry and business_model, and says nothing about how the nested `patch` merges or how idempotency_key should be used.

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?

States a specific verb+resource ("Update project context") and enumerates the mutable fields, so the agent knows exactly what the tool touches. It does not, however, distinguish itself from siblings like hypotize_project_create or hypotize_project_delete beyond the verb 'update'.

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 role requirement (editor/owner) implies when the call will succeed, which is useful. But there is no explicit when-to-use versus alternatives guidance, no statement of when-not-to-use, and no direction toward sibling tools such as project_get or project_create.

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