suggest_cuts

Read-onlyIdempotent

Identify the weakest cards to cut from a Commander decklist. Scores cards by synergy, inclusion rate, and combo membership, using available data from EDHREC and Spellbook if possible.

Instructions

Identify the weakest cards to cut from a commander decklist.

Scores cards by synergy, inclusion rate, and combo membership. Degrades gracefully if EDHREC or Spellbook backends fail (uses whatever data is available).

Behavior5/5

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

Annotations already provide readOnlyHint, openWorldHint, idempotentHint. The description adds valuable behavioral context: scoring logic and graceful degradation on backend failure. No contradiction with annotations.

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?

Three concise sentences: core purpose, scoring criteria, and graceful degradation. No unnecessary 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?

The description lacks explicit mention of the output format (e.g., list of card names). Since there is no output schema, providing this would improve completeness. Otherwise, the tool is well-described.

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 coverage is 100%, so baseline is 3. The description does not add parameter-specific details beyond the schema descriptions, which are already clear.

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 tool identifies the weakest cards to cut from a commander decklist, with specific criteria (synergy, inclusion rate, combo membership). It distinguishes itself from siblings like deck_analysis by focusing on cuts.

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

Usage Guidelines4/5

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

The description explains when to use the tool (to identify cuts) and mentions graceful degradation, but does not explicitly mention when not to use it or suggest alternative tools for different analyses.

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