Set Project Repo Path

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

No annotations are provided, so the description carries the full burden of disclosing behavior. It does state the write operation ('set or update') and a downstream effect (affects session brief content). However, it does not disclose whether an existing path is overwritten, whether the operation is reversible, what validation occurs beyond the .git requirement, or what the tool returns, leaving notable gaps for a mutation tool with zero annotation coverage.

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 concise sentences with no filler: the first states the action and target, the second explains why the tool matters. The most important information is front-loaded, and every sentence 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 tool with two scalar parameters, full schema coverage, and no nested objects, the description provides the essential information: what the tool does, what its prerequisite is, and why it is needed. It could add details about overwrite behavior or response format, but nothing critical is missing for an agent to invoke it 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 100%, with both 'project' and 'repo_path' already described in the input schema. The description adds only the contextual relationship to git activity, not new parameter-level meaning, so the baseline 3 is appropriate.

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 ('Set or update') and names a precise resource ('local git repository path for a project'), and it adds the downstream purpose (enabling git activity in the session brief). It is not a tautology and clearly distinguishes this tool from the listed siblings, none of which cover this action.

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 states the condition for using this tool: it is required when the session brief must include git activity such as commits, branch, and working-tree state. It does not explicitly name alternatives or say when not to use it, but the contextual cue is strong enough for an agent to route correctly.

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