pyp6xer_write_file

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

Annotations already indicate idempotentHint=true and not read-only/not destructive. The description adds that it serializes raw table data including updates from specific sibling tools, providing context beyond annotations. No contradictions.

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?

Two sentences, front-loaded with the primary action, and no extraneous information. Every sentence adds value.

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, the description covers the key aspects: writing the current schedule to a file, referencing update tools, and specifying the output path. An output schema exists, so return values need no explanation. Minor missing piece: no mention of prerequisites like file must be loaded, but the cache_key parameter implies this.

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% with descriptions for both parameters. The description adds that output_path is the local file path and cache_key identifies the loaded file, but this largely mirrors schema. It does not introduce new parameter semantics beyond what the schema provides.

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 action ('Write') and the resource ('.xer file'), specifying it serializes the current modified schedule. This distinguishes it from sibling tools like pyp6xer_export_xer by emphasizing in-memory state.

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 use after modifications (e.g., from pyp6xer_update_activity), but does not explicitly state when to use this tool versus alternatives like pyp6xer_export_xer. No 'when not to use' guidance is provided.

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