create_branch

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

With no annotations, the description carries the full burden for a mutation tool, yet it discloses nothing about permissions, idempotency (despite an operation_id parameter), side effects on the root task, or whether the branch can later be merged.

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 front-loaded sentence with no filler, but 'through Core T1' is unexplained jargon that consumes space without adding actionable meaning.

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 7-required-parameter mutation with no annotations, no output schema, and zero parameter documentation, one sentence is far short of what an agent needs to invoke this 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 0% across 8 parameters, so the description must compensate and does not: it never explains root_task_id, workspace_id, operation_id, sender/recipient/subject/body, or the P2 priority default. Worse, it references a 'branch_of relation' that has no corresponding parameter in the schema, which misleads more than it informs.

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 and resource ('Create a branch TASK') and distinguishes itself from the plain create_task sibling by calling out the branch_of relation. The jargon 'Core T1' is undefined, but the core action is still identifiable.

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?

No guidance on when to use this instead of create_task or merge_branches, and no prerequisites such as whether root_task_id must reference an existing task or what distinguishes a branch task from a root task.

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