Dbg Delete Bp

dbg_delete_bp

Deletes one or more debugger breakpoints by address in an IDA Pro instance, accepting a single or comma-separated address list and an optional instance ID for multi-database sessions.

Instructions

Delete breakpoint(s) at address(es).

C2.9/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full behavioral burden, yet it only states the operation. It does not explain deletion semantics, idempotency, error behavior for missing addresses, or the multi-instance requirement beyond what the schema already says.

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?

A single front-loaded sentence with no wasted words. It is exactly as long as the stated purpose requires, though that is also why it omits useful context.

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

Completeness2/5

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

For a mutation tool with no annotations and no output schema, the description is under-specified. It omits behavioral context an agent would need, such as whether deleting a nonexistent breakpoint errors and how instance_id affects the operation across multiple open databases.

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%, so the schema already documents addr, timeout, and instance_id, including that addr can be comma-separated. The description adds no syntax or meaning beyond restating that addresses are involved, so the baseline 3 is appropriate.

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 uses a specific verb and resource: deleting breakpoint(s) at address(es). It is clearly distinct from the add/enable/list breakpoint siblings, though it does not explicitly name or differentiate against those alternatives.

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?

It gives no explicit when-to-use guidance, exclusions, or alternatives. An agent must infer that this is the removal operation versus disabling a breakpoint with dbg_enable_bp or inspecting with dbg_list_bps.

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