bridge_router_version

Check router surface version and method count to negotiate capabilities, issuing a soft warning on mismatch without enforcing a hard lock.

Instructions

Router surface version + method count (capability negotiation; soft-warn on mismatch, never hard-lock).

detail (str | None): full (default) | summary (long lists cut to 25 + count) | minimal (top-level scalars only).

response_format (str | None): yaml (default, token-cheap) | json.

TDQS

A3.7/5.0
Behavior3/5

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

No annotations are provided, so the description carries the burden. It discloses the soft-warn vs hard-lock behavior, which is useful. However, it doesn't describe what happens on mismatch in detail, error behavior, or whether this is a read-only operation. The description adds some behavioral context but not comprehensive.

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?

The description is compact and front-loaded with the core purpose. The parameter details are listed efficiently. It could be slightly more structured, but every sentence earns its place.

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

Completeness3/5

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

For a simple 2-param tool with no output schema, the description covers the main purpose and parameter semantics. However, it lacks information about return value structure, error handling, and when to prefer this over bridge_status or bridge_health. It's adequate but has clear gaps.

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?

Schema description coverage is 0%, so the description must compensate. It does: it explains the 'detail' parameter's three modes (full, summary, minimal) and the 'response_format' parameter's two options (yaml, json) with their defaults and trade-offs. This adds significant meaning beyond the bare 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?

The description states a specific verb and resource: 'Router surface version + method count' for capability negotiation. It distinguishes itself from siblings like bridge_status and bridge_health by focusing on version and method count, though it doesn't explicitly name those siblings.

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

Usage Guidelines4/5

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

The description gives clear context: it's for capability negotiation, with a soft-warn on mismatch and never hard-lock. It doesn't explicitly say when not to use it or name alternatives, but the negotiation purpose is clear enough for an agent to select it appropriately.

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