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

Annotations already indicate read-Only, idempotent, non-destructive behavior. The description adds that it is derived from multiple sources, but does not explain whether the plan is dynamically computed or static, or how it reflects task progress updates. With annotations covering the basic safety profile, the description adds moderate value.

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 that conveys the core purpose and data sources, without unnecessary words. It is front-loaded with the main action ('Return the current methodology task plan').

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 retrieval tool with three parameters and no output schema, the description should clarify the expected content of the plan and how parameters influence it. It lacks guidance on what constitutes a 'task plan' and how it relates to research runs or case studies, leaving the agent to guess.

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?

With 0% schema description coverage and no parameter documentation in the description, the agent has to infer that 'limit' controls result count and that caseStudyId/researchRunId filter the plan. The description does not explain how these parameters affect the returned plan, which is a significant 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 clearly states the tool returns the current methodology task plan, specifying its sources (case-study ledger, research notebook, evidence maturity, MCP task-progress notes). This distinguishes it from siblings like ata_get_research_notebook or ata_get_evidence_maturity, which would return individual components.

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 it's used to retrieve the current plan, but does not explicitly contrast with sibling tools that might also return plan-like information (e.g., ata_plan_case_study_hardening). No guidance on when to use this versus other getters or planning tools is provided.

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