gsd_execute_phase

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

The description adds 'in parallel waves' as a behavioral trait beyond the tool name, giving the agent awareness of concurrency. However, it does not disclose side effects, failure handling, or return values. With no annotations, this is partial but non-trivial disclosure.

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?

The description is a single sentence with no filler or redundancy. It front-loads the core action and the concise phrasing is effective for a tool with a simple one-parameter schema.

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?

The description is minimal for an execution tool with no annotations and no output schema. It does not explain what 'execute' entails, what a 'wave' is, what prerequisites exist, or what the agent should expect as a result, leaving significant ambiguity about the operation's impact.

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?

The sole parameter 'phase' is already well-documented in the input schema with its own description. The tool description only reuses the concept without adding additional semantic detail, meeting the baseline for full schema coverage.

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 the specific verb 'execute' with a clear resource ('all plans for a phase') and adds execution style ('in parallel waves'). This distinguishes it from sibling tools like gsd_plan_phase (planning) and gsd_phase_complete (completion).

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 is provided on when to use this tool versus alternatives. There is no mention of prerequisites, workflow position, or exclusions; the description only states the action itself.

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