manage_session

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

No annotations exist, so description carries full burden. It reveals three actions (create, checkpoint, restore) and mentions 'across conversations', signaling persistence scope. However, it does not disclose details like whether checkpoints are retained indefinitely, if there are size limits, or side effects like overwriting previous checkpoints when creating a new one. Adequate but not rich.

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 that says exactly what the tool does. Front-loaded with the key concept (managing sessions for checkpoint/restore). No filler, no redundancy with schema. Perfectly concise.

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 output schema exists (agents can inspect return structure) and full parameter documentation, the description covers the essential purpose. It is a generic session management tool, not overly complex. The one-line description plus rich schema is sufficient. Could mention that sessions persist across conversations, but that is already implied.

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 100%, but the description adds no parameter-level detail beyond the schema. Baseline starts at 3 for full coverage; the description earns a 4 because the schema itself is very descriptive (documents which params are for which action, defaults, required status, and data types), so the description doesn't need to repeat. Minimal added value, but the schema does the work.

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 manages sessions for checkpoint/restore of agent state. It distinguishes from memory-related sibling tools which focus on recall/store/update operations, not session lifecycle management.

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 for saving and restoring agent state across conversations but does not explicitly state when to use this vs memory tools. No guidance on when to create vs checkpoint vs restore, or prerequisites like needing a session_id for checkpoint/restore. The context of 'across conversations' is helpful but implied.

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