Workspace cost report (admin)

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

With no annotations, the description carries the full burden, and it only discloses scope (all users in this workspace). It does not state that the title's 'admin' implies a permission requirement, does not define the reporting time window (critical for a cost report), and does not say whether results are aggregated or per-user.

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?

One short sentence with the scope front-loaded ahead of the qualifier — no waste. The vague closing phrase 'budget posture' is the only weak element, but it costs little space.

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 zero-parameter tool with no output schema, the description should at least sketch what comes back and over what period. Instead it leaves the reporting window, aggregation level, and 'budget posture' meaning entirely unstated, and never confirms the admin permission named in the title.

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 there is nothing for the description to disambiguate; baseline is 4. The schema is empty and correctly needs no compensation.

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?

States a specific resource (cost report) plus scope (across all users in this workspace), which meaningfully separates it from the sibling get_cost_report. The trailing phrase 'with budget posture' is vague and undefined, so the purpose is clear but not fully pinned down.

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?

No when-to-use guidance is given and no alternative is named. An agent must infer from the word 'all' that this is the workspace-wide variant and get_cost_report is the narrower one, which is inference rather than instruction.

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