get_phase_4_guidance

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

With no annotations provided, the description carries the full burden. It transparently explains the tool returns a markdown-formatted guide and lists the content (objectives, steps, tools to use, expected outputs). It does not mention side effects, which is acceptable for a read-only retrieval tool.

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 well-structured with an overview and a documentation-style Args/Returns section. It is somewhat verbose for a tool with no parameters, but remains concise and front-loaded with the primary purpose.

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 the tool's simplicity (no input parameters, static guidance retrieval), the description sufficiently covers the output format and content. The existence of an output schema further reduces the need to explain return values. It is complete for its intended use.

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 input schema has zero parameters, so the baseline is 4. The description mentions a 'ctx' argument, but it is not in the schema. This is not contradictory and adds slight context about the implementation, but does not harm semantic clarity.

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 clearly states 'Get detailed guidance for Phase 4: Trust Boundary Analysis' with a specific verb and resource. It distinguishes itself from sibling tools by phase number (Phase 4) and topic, unlike generic phase guidance tools.

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 implies the tool is used when you need step-by-step guidance for trust boundary analysis, but it does not explicitly state when to use it versus other phase guidance tools or alternatives. It lacks exclusionary or alternative recommendations.

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