build_reproduction_binding

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

With no annotations provided, the description carries the full burden. It does disclose two important behavioral traits: the tool does not execute the command and does not read environment values. However, it does not disclose side effects, whether state is mutated, or what a 'binding' actually produces beyond the output schema.

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 that states the purpose first and appends the constraints. Every word earns its place with no filler.

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 10-parameter tool with zero schema coverage and no annotations, the description is incomplete. It never explains what an 'RB/1 reproduction binding' is for, what output the agent should expect (despite an output schema), or what distinguishes this build step from related reproduction/execution tools among the many siblings.

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% across 10 parameters, so the description must compensate. It loosely maps 'files' to input_paths and 'Git metadata' to git_commit, and 'environment values' to environment_names, but leaves command, cwd, exit_code, stdout_sha256, stderr_sha256, max_hash_bytes, and output_artifact_id entirely unexplained. This is insufficient compensation for the coverage gap.

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 names a specific verb ('Build') and a specific resource ('RB/1 reproduction binding'), and states the data sources (current files/Git metadata). It also conveys key constraints (no command execution, no environment reads). It doesn't explicitly differentiate from siblings, but the 'RB/1' qualifier plus the non-execution constraint make it reasonably distinguishable.

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 phrase 'without executing the command or reading environment values' implies an offline/metadata-only mode, which is a soft usage hint. However, there is no explicit guidance on when to choose this over alternative tools or when not to use it — no named siblings or conditions are given.

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