langfuse-mcp-extended

deleteScore

Removes a specific score from Langfuse using its unique identifier. This action permanently deletes the score and cannot be undone.

Instructions

Delete a specific score. This action is irreversible.

Input Schema

NameRequiredDescriptionDefault
scoreIdYesThe unique score identifier to delete
Behavior2/5

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

No annotations are provided, so the description carries full burden. It only mentions irreversibility but lacks details on authorization, side effects on associated data, or whether any confirmation is needed. Inadequate for a destructive operation.

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?

Extremely concise and front-loaded: two sentences that convey purpose and a critical behavioral note. No wasted words.

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?

Given the tool's simplicity (one required parameter, no output schema), the description covers the core purpose and irreversibility. It could mention that only the score record is deleted (no cascading effects) for completeness, but it's adequate.

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% (scoreId is well described). The description adds no extra meaning beyond the schema—both state essentially the same thing. Baseline 3 is appropriate.

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?

The description clearly states the action (delete), the resource (specific score), and emphasizes irreversibility. It unambiguously distinguishes from sibling tools like createScore or getScore.

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?

No explicit guidance on when to use this tool versus alternatives. There is no mention of prerequisites, permissions, or scenarios where deletion is appropriate or inadvisable.

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