bisect_end

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

No annotations are provided, so the description carries the full burden. It omits the things that matter for a session-terminating tool: what happens to an unconverged bisect (is a result committed, discarded, or marked aborted?), whether the call is idempotent, and what the response contains. The remaining text is a pricing advertisement, not behavioural disclosure.

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

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

The useful information is confined to one front-loaded sentence. The following three lines about Free/Pro tiers, mid-print edits, and an upgrade URL are pure marketing that occupies more space than the actual tool documentation and dilutes the signal.

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

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

For a state-changing tool with no annotations and no output schema, the description should explain side effects, session-state requirements, and return behaviour. Instead it spends most of its length on tier promotion, leaving an agent unable to predict what ending the bisect actually does.

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

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

Schema description coverage is 0% and the single required parameter (session_id) is never mentioned in the description. It does not say where to obtain a session id (e.g., from list_bisect_sessions or bisect_start) or what format it takes, so the description fails to compensate for the coverage gap.

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

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

The first sentence states a specific verb and resource: 'End a bisect session'. That is unambiguous and an agent can identify the operation. However, it never contrasts itself with the surrounding bisect siblings (bisect_start, bisect_good, bisect_bad, bisect_current, list_bisect_sessions), so it stops short of a 5.

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

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

The phrase 'without requiring full convergence' hints at when early termination is acceptable, but the description never says when to call this instead of bisect_good/bisect_bad, nor what state the session must be in. No alternatives and no prerequisites are named.

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