get_rowFetch a single row by its key from a v2 app collection, through a dedicated relay route rather than a client-side scan. Returns { row }, or an isError row_not_found.
| Name | Required | Description | Default |
|---|---|---|---|
| key | Yes | The key of the row to fetch. | |
| app_id | Yes | The app id. | |
| collection | Yes | The collection name. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate readOnlyHint=true, so the description adds value by disclosing the route method (dedicated relay route vs. client-side scan) and the return format with error handling, providing context beyond the annotations.
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 action, no wasted words. Every sentence contributes meaningful information.
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 simple read-only tool with 3 required parameters and no output schema, the description fully covers functionality, route method, return format, and error case, making it 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?
Schema coverage is 100% with parameter descriptions provided. The description does not add significant meaning beyond the schema, so baseline 3 is appropriate.
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 verb 'Fetch', the resource 'a single row by its key from a v2 app collection', and distinguishes the tool from siblings by mentioning the dedicated relay route and specific return format.
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?
While the purpose is clear, the description does not explicitly state when to use this tool versus alternatives like list_rows, update_row, or delete_row. It implies usage for direct key-based access but lacks explicit when-not or alternative guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool targets a distinct resource or action: row operations (get/list/upsert/update/delete/restore) are clearly separated, while apps, attachments, community, grants, ingest, members, publisher, review, and taste each cover a different domain. Even closely related actions like share_link_rotate and domain_set have clearly scoped descriptions, so an agent can reliably select the right tool.
Tool names use two patterns: noun-like names for resource areas (apps, attachments, community, grants, ingest, members) and verb_noun names for row operations (upsert_row, delete_row, etc.). This deviation is predictable and readable, but it is not perfectly uniform, so a slight deduction applies.
With 22 tools, the server is on the heavier side, but the breadth of the platform (app lifecycle, data storage, attachments, community, reviews, feedback, identity) justifies the count. Each tool represents a meaningful feature area with multiple internal actions, so none feels redundant.
The tool surface covers the full lifecycle for apps (create, read, update, delete), rows (create, read, update, delete, restore, list deleted), attachments, membership, grants, ingest, community, and reviews. Obvious gaps like rollback or version history are not core to the domain, and the presence of get_skill helps agents understand the workflow.
