plan

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

With no annotations, description bears full burden. States 'safe for exploration' and 'without executing', but does not detail what happens to plans, whether they persist, or any side effects. Basic disclosure is present but not comprehensive.

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?

Single sentence, directly states purpose and safety. No unnecessary words; front-loaded and efficient.

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 planning tool with 3 parameters and no output schema or annotations, description is minimal. It covers safety but lacks details on expected output, plan lifecycle, or integration with sibling tools like execute_plan. Adequate but not comprehensive.

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%, so baseline 3. Description adds 'without executing' but does not enrich parameter meanings beyond what schema already provides (e.g., 'task' is simply reiterated as 'analyze, design, and plan').

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 the tool's function: 'analyze, design, and plan without executing'. This differentiates it from sibling tools like execute_plan which performs execution.

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 says 'without executing' and 'safe for exploration', implying use for analysis without side effects. However, no explicit when-not-to-use or mention of alternatives beyond context.

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