scaffold_judge

Generate boilerplate files for a new judge: definition, evaluator skeleton, and index.ts line. Validates uniqueness of judge ID and rule prefix.

Instructions

Generate the boilerplate files to add a new judge to the Judges Panel. Creates the judge definition (with self-registration), evaluator skeleton, and tells you the one line to add to index.ts. Validates that the judge ID and rule prefix are unique.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
idYesUnique kebab-case judge identifier (e.g., 'supply-chain', 'code-review')
nameYesHuman-readable judge name. Must start with "Judge " (e.g., "Judge Supply Chain")
domainYesExpertise area (e.g., "Supply Chain Security")
dryRunNoIf true, preview the generated files without writing to disk (default: false)
rulePrefixYesUppercase prefix for rule IDs (e.g., "SCS"). Must be unique across all judges.
descriptionYesOne-sentence summary of what this judge evaluates
samplePatternsNoExample code patterns the evaluator should detect (strings or regex snippets). Used to seed the evaluator with starter detection logic.
tableDescriptionYesComma-separated keywords for the README table (e.g., "Dependency provenance, SBOM, build integrity")
promptDescriptionYesShort action phrase for the prompts table (e.g., "Deep supply chain security review")
evaluationCriteriaNoList of evaluation criteria / categories to include in the system prompt (e.g., ['Dependency provenance', 'Build integrity'])
Behavior3/5

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 mentions validation of ID and rule prefix uniqueness but does not disclose whether file creation is destructive, what happens on validation failure, or if it modifies index.ts directly. Some behavioral traits are missing.

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. First sentence immediately states the tool's main function (generate boilerplate), second adds validation. No wasted words, front-loaded with key action.

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

Completeness3/5

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

Description lacks details on return value, error handling, and the effect of the dryRun parameter. Given no output schema and no annotations, more context about the generation process and its outcomes would be beneficial.

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 all 10 parameters. The description adds minimal value beyond summarizing the purpose and restating the uniqueness validation. 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?

Description clearly states it generates boilerplate files for a new judge, creates definition, evaluator skeleton, and provides the line to add to index.ts. The verb 'scaffold' + resource 'judge' is specific and distinguishes from siblings like scaffold_plugin.

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?

The description implies usage for adding a new judge but does not explicitly state when to use this tool versus alternatives like scaffold_plugin or when not to use it. No comparison with siblings is provided.

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