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

Annotations already carry destructiveHint=true, readOnlyHint=false, and openWorldHint=true, so the bar is lower. The description adds valuable behavioral context beyond them: API key requirement, per-action credit costs, async submit-then-poll behavior, monitor re-check cadence, and idempotency semantics. It does not detail destructive consequences, but destructiveHint and action names like delete/cancel/close provide the baseline warning.

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?

The description is dense but every clause earns its place: it front-loads the purpose, organizes 23 actions into sync, async, monitor, and browser groups, and attaches pricing, docs pointer, and auth requirements. For the breadth of this tool, the length is justified and there is no filler.

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 tool with no output schema and a large action surface, the description is remarkably complete: it covers workflows, auth, costs, and points to get_docs for the full per-action parameter list. It leaves response shapes and detailed error semantics to the docs, which is a reasonable trade-off given the scope.

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 description coverage is 100%, so the baseline is 3 even without parameter information in the tool description. The description enriches action semantics but does not add per-parameter detail beyond what the input schema already provides for action, id, input, and idempotencyKey.

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 opens with a clear, agent-facing purpose: 'Full web scraping, search, and browser automation (Firecrawl-backed),' then enumerates the action groups and their outputs. It is specific enough about what the tool does, though it does not explicitly contrast itself with sibling tools like socialcrawl_request or socialcrawl_monitors.

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 gives strong internal routing guidance: sync reads vs. async jobs, monitor cadence with webhook, interactive browser sessions, and even a free crawl_preview dry-run. It does not state explicit 'when not to use' conditions or compare against sibling alternatives, but for this broad umbrella tool the action-level guidance is quite usable.

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