get_branch_context

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

Describes the output (branch, HEAD SHA, recent commits) but lacks detail on what constitutes 'recent commits' (e.g., count, ordering). No annotations provided, so description carries full burden; minimal transparency.

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 purpose and immediate usage instruction. No redundant or unnecessary text; every word serves a function.

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 zero parameters and no output schema, the description adequately conveys the tool's output and purpose. However, could be expanded slightly to specify commit count or format for better completeness.

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?

No parameters exist (0 params, 100% schema coverage). The description adds value by specifying the output fields, which is the only relevant semantic information.

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?

Description clearly states what the tool does: get current git branch, HEAD SHA, and recent commits. The verb 'Get' and specific resources distinguish it from siblings like get_all_changes or get_changed_files.

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?

Explicitly instructs to call this first to anchor context to the correct branch, providing a clear usage sequence. Does not mention alternatives directly, but the instruction strongly implies its primary role.

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