Destructive

Simulate network conditions for a browser tab. Choose presets like offline, slow-2g, 3g, or set custom download/upload speed and latency.

Instructions

Simulate network conditions.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
tabIdYesTab ID
presetYesNetwork preset
downloadKbpsNoDownload Kbps (preset=custom only)
uploadKbpsNoUpload Kbps (preset=custom only)
latencyMsNoLatency in ms (preset=custom only)
output_modeNo"inline" (default): return the full payload in-band — byte-identical to v1.11.0. "handle": write payload to the handle store and return a small descriptor; redeem with oc_output_fetch. "auto": inline if payload ≤ output_inline_limit_bytes, otherwise handle.
output_inline_limit_bytesNoOnly honored when output_mode="auto". If the serialized payload exceeds this byte count the response spills to a handle. Default: 32768.
Behavior2/5

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

Annotations already indicate destructiveHint=true and openWorldHint=true, but the description adds no extra behavioral details (e.g., whether changes persist, effect on browser, error scenarios). Does not contradict annotations.

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

Conciseness2/5

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

Extremely short (one sentence) for a tool with 7 parameters. Lacks structure and important context, bordering on under-specification rather than conciseness.

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

Completeness2/5

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

No output schema and minimal description. Fails to explain return values, side effects, or usage patterns, leaving significant gaps for a tool that modifies network conditions.

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 description coverage is 100%, so the schema already documents parameters. The description adds no additional meaning beyond the schema, earning baseline 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

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

The description 'Simulate network conditions.' conveys the general purpose but fails to differentiate from sibling tools like network_capture_full or oc_get_connection_info. It lacks specificity about what 'simulate' entails (e.g., throttling, offline mode).

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

Usage Guidelines2/5

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

No guidance on when to use this tool vs alternatives, no preconditions or postconditions mentioned. The description is too vague to help an agent decide contextually.

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