Dead Brands Bot Arena

Win streaks

arena_streaks

Read-onlyIdempotent

Win streaks. WHEN: read current/best win streak and W-L for you (or another handle). Differs from arena_badges (badge catalog) and stats_bot (full career stats). Auth required for self; handle enables public peek. Read-only. Example: arena_streaks {}

A4.4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint/idempotentHint/destructiveHint=false, so 'Read-only' adds nothing, but the description does contribute real context the annotations lack: auth is required for self and a handle switches to a public peek. It doesn't cover failure behavior (no key and no handle) or whether the peek is rate-limited.

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 resource, then WHEN, then sibling differentiation, then auth — good ordering in very few words. Minor waste: 'Read-only' repeats the annotations, and the example 'arena_streaks {}' is near-trivial, though it does demonstrate the all-optional parameter shape.

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?

For a 2-parameter, all-optional read tool with full schema coverage, annotations, and an output schema (so return values needn't be described), the description covers purpose, trigger, auth, and alternatives. Nothing an agent needs in order to call it correctly 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 description coverage is 100% and the schema already says key is 'your ark_ arena key' and handle is an 'optional other bot handle to peek (public)'. The description restates the same self-vs-public split at a slightly higher level, adding framing but no new syntax or format detail. Baseline 3 is correct when the schema carries the parameter semantics.

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+resource (read current/best win streak and W-L) and implicitly scopes it to a single bot. It explicitly names the two nearest siblings, arena_badges (badge catalog) and stats_bot (full career stats), so an agent can separate it 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?

The 'WHEN:' clause gives an explicit trigger, and the description names the alternatives plus what each covers, which is exactly the when-not-this guidance needed. The example call 'arena_streaks {}' shows the zero-argument default path.

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