scout_crawl

Sweep known unvisited routes in one call, record coverage, and return per-route health summaries with HTTP status, oracle violations, and dead-ends; explore interactively only where issues appear.

Instructions

Engine-side route sweep in ONE call: visits each path (default: all known routes not yet visited), records states into coverage memory, and returns a per-route health summary (HTTP status, element count, what the main area holds, oracle violations, dead-ends, auth-redirects, and ERROR-VIEW or STILL-LOADING for a main area showing only an alert or a loading placeholder). Navigation-only — safe in read-only mode. Use this FIRST for broad coverage; explore interactively only where it flags problems or where journeys matter.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
pathsNoPaths to visit, e.g. ['/orders','/settings'], or full URLs on the attached origin. A path resolves from the origin's root, whatever page the session attached on. Omit to crawl all unvisited known routes.
sessionNoTarget this session directly instead of the active one — pass it explicitly when dispatching to MULTIPLE sessions in one turn (e.g. two scout_click calls with different `session`), which then run CONCURRENTLY rather than queueing. Omit for single-session sequential use.

A4.6/5.0
Behavior5/5

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

With no annotations present, the description carries the full burden and delivers: it discloses side effects (records states into coverage memory), the safety profile ('Navigation-only — safe in read-only mode'), and the exact per-route signals returned (status, element count, oracle violations, dead-ends, auth-redirects, ERROR-VIEW/STILL-LOADING). This is unusually complete behavioral disclosure for an unannotated tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the core action and scope in the first clause, then the output shape, then the routing guidance. The long parenthetical enumerating return signals is dense but each item earns its place; slightly heavy but not wasteful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema exists, and the description compensates by enumerating what the health summary contains, plus safety and coverage-memory side effects. Nothing an agent needs to call this correctly against its 35 siblings is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents both parameters, including the default-to-unvisited-routes behavior and the concurrent multi-session use of `session`. The description adds no parameter-level detail 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.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('route sweep... visits each path') plus the default scope (all known routes not yet visited) and the return artifact. An agent can distinguish it from interactive siblings like scout_click/scout_navigate without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly says 'Use this FIRST for broad coverage; explore interactively only where it flags problems or where journeys matter,' giving both the when-to-use and the when-to-use-alternatives condition. This directly routes the agent between this bulk crawler and the interactive tools.

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