Orient in the SandboxAPIs universe

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

With no annotations, the description carries the full behavioral burden and does so well: it declares the server READ-ONLY even for scratch-enabled keys, explains that the scratch layer is a 24-hour per-key overlay backed by REST (and which surfaces it touches), states responses come from the shared data set alone, and reports key/rate-limit status in the access block.

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?

Content is front-loaded with 'START HERE' and every clause is substantive, but it is delivered as two long run-on sentences that are hard to scan. The writes/scratch-layer discussion in particular would benefit from being broken into shorter, ordered statements.

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?

There is no output schema or annotations, so the description must be self-sufficient, and it is: it covers the returned contents, the live-vs-snapshot modes, the write policy and where writes actually happen, and the access block fields. Nothing an agent needs to call a zero-argument orientation tool correctly is missing.

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?

The tool takes zero parameters, so per the rubric the baseline is 4; there is no argument surface the description needs to compensate for. No additional parameter meaning is required.

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?

Names a specific action and enumerates exactly what the tool returns (universe/theme, API surfaces with base URLs, modes, org/teams/repos, entry points, coverage manifest, access block), which lets an agent distinguish it from narrow siblings like get_snapshot or check_budget. The opening 'START HERE' frames it as the entry-point orientation call.

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?

'START HERE' is explicit guidance on when to call it, and the writes paragraph routes the agent to the GitHub/Jira/Slack REST base URLs for scratch-layer operations rather than the tools. It does not, however, explicitly state when to prefer it over siblings that overlap (get_snapshot, check_budget).

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