bridge_traffic

Report exact bridge traffic stats: per-lane toll challenges vs paid crossings, unique payer wallets, and first/last seen times. Shows only what the bridge has observed, no estimates.

Instructions

Mini's TrollBridge — FREE bridge statistics: per-lane toll challenges (lookers) vs paid crossings (agents through), unique payer wallets, first/last seen. Honest day-one ledger: traffic is small and growing; this tool reports exactly what the bridge has seen, nothing more.

B3.3/5.0
Behavior3/5

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

With no annotations, the description carries the full burden. It does add real behavioral context: the service is free and 'traffic is small and growing' with 'exactly what the bridge has seen, nothing more', which usefully warns the agent that results may be sparse and unembellished. However it says nothing about auth requirements, call cost/latency, or failure behavior, so the disclosure is partial.

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

Conciseness3/5

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

The metric list is front-loaded in the first sentence, which is good, but the passage is padded with branding ('Mini's TrollBridge', 'Honest day-one ledger') and idiosyncratic terms that spend words without adding usable meaning. Every sentence does carry some signal, so it is adequate rather than wasteful.

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

Completeness4/5

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

For a no-parameter tool with no output schema, the description is the only place the returned fields can be described, and it does list them (toll challenges, paid crossings, unique wallets, first/last seen). The main residual gap is that it never sketches the output shape or units, so an agent still doesn't know how these metrics are packaged.

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

Parameters4/5

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

The tool takes zero parameters, so the schema cannot be misread and there is no parameter semantics to document; the baseline for 0-param tools is 4. Nothing in the description contradicts or confuses the empty schema.

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

Purpose4/5

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

It names the resource (bridge statistics) and enumerates the specific metrics returned: per-lane toll challenges vs paid crossings, unique payer wallets, first/last seen. This is concrete enough for an agent to know it is a read-only traffic-reporting tool, but the branded jargon ('lookers', 'agents through', 'TrollBridge') requires interpretation and it never distinguishes itself from siblings like bridge_health or bridge_fresh.

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?

There is no statement of when to use this tool versus the 17 sibling bridge_* tools, and no exclusions or prerequisites. 'FREE' hints at cost but conveys no selection guidance. An agent has to infer that this is the traffic-metrics endpoint on its own.

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