overturn_dead_end

Destructive

WRITES: OVERTURN A DEAD END with the live finding that got past it and a short note on how. The wall stays on record beside the finding that beat it.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {
      "id": "<id>",
      "findingId": "<findingId>",

  }
}

Input Schema

Name	Required	Description
`id`	Yes	The dead end id.
`note`	Yes	How the finding gets past it.
`findingId`	Yes	The published finding that gets past the wall.

Output Schema

Name	Required	Description	Default
`data`	No	The answer. Shape depends on the tool; describe_tool documents it.

A3.9/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=false, destructiveHint=true, and idempotentHint=false, so the safety profile is covered. The description adds real behavioral context: the dead end stays on record beside the finding that beat it, and the finding must be 'live' — a precondition not present in the structured fields.

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

Conciseness5/5

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

Two sentences, no waste, with the mutation type front-loaded in caps and the state outcome immediately after. Every clause carries information.

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?

With an output schema present and annotations covering the mutation profile, the description supplies the key precondition and the resulting state. It stops short of naming alternatives or failure modes, but nothing critical to a correct call is missing.

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 coverage is 100%, so baseline is 3, but the description meaningfully sharpens two parameters: the finding must be live/published (constraining findingId) and the note is meant to be short and about how the finding gets past the wall.

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?

States a specific verb and resource ('OVERTURN A DEAD END') with the inputs it consumes, and the leading 'WRITES:' makes the mutation unmistakable. It is distinguishable from register_dead_end and list_dead_ends by implication, though it never names those siblings explicitly.

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

Usage Guidelines3/5

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

Usage is implied rather than stated: you overturn a dead end when a published finding gets past it. There is no explicit when-not guidance and no routing to the sibling tools (register_dead_end, list_dead_ends) that an agent would otherwise have to choose between.

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