Get State At Timestamp

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

Annotations already declare readOnlyHint=true and destructiveHint=false. Description adds that the tool reconstructs the state from nodes and edges, and that it is a point-in-time snapshot. Does not elaborate on caveats like data source or availability, but given the read-only annotation, this is sufficient.

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, front-loaded with the main action, no redundant words.

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?

Description covers the tool's core behavior and output type (state as nodes and edges). No output schema exists, but the description implies the return value. For a read-only query tool with two well-described parameters, this is adequately complete.

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?

Input schema has 100% coverage with descriptions for both 'project' and 'timestamp'. The description reinforces the timestamp parameter but does not add new semantics beyond schema. Baseline 3.

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 uses specific verb 'reconstruct' with resource 'historical state memory (nodes and edges)' and qualifier 'at a specific ISO timestamp'. Clearly distinguishes from sibling tools like get_node_history or get_context_snapshot by focusing on full state at a point in time.

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?

Description implies usage when needing historical full-state at a timestamp, but provides no explicit alternatives or exclusions. Sibling tools like revert_to_timestamp or get_node_history are not mentioned, so agent must infer when to choose this over them.

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