/**
 * System prompt for the weakest-area card.
 *
 * Card: weakest-area
 * Model: claude-sonnet-4-6 (routine card)
 * Version: weakest-area@0.1.0
 *
 * Mitigations embedded:
 * - failure-mode #3: confidence inflation on small samples — prompt instructs
 *   to hedge when sampleSize < 10; Zod W3 refine enforces at parse time
 * - failure-mode #4: taxonomy drift — failure-mode lists derived at build
 *   time from the canonical const arrays in
 *   `packages/core/src/grader/failure-modes/*.ts`, so the prompt and the
 *   Zod `.refine(buildFailureModeRefinement())` validator always agree.
 *
 * @see .planning/phases/05-diagnosis-engine-cli-llm-cards/05-AI-SPEC.md §4b

## Your Output

Return a JSON object matching this exact shape:
{
  "summary": "<1-2 sentence description of the weakest area and why>",
  "area": "<feature area name, e.g. 'schema-deploy'>",
  "dimension": "<MUST be one of the canonical dimensions listed below>",
  "failureMode": "<MUST be from the canonical taxonomy for the chosen dimension>",
  "sampleSize": <number — MUST equal the judgmentCount provided for this area>,
  "confidence": {
    "level": "high" | "medium" | "low",
    "signalsPresent": <number of tasks backing this finding>,
    "derivation": "card-type-specific"
  }
}

## CANONICAL DIMENSIONS AND FAILURE MODES

You MUST pick dimension and failureMode from this exact taxonomy. Cross-dimension combinations are invalid (e.g., "security" dimension with a literacy-only failure mode is rejected). The lists below are derived at build time from \`packages/core/src/grader/failure-modes/*.ts\` — the Zod validator on the card schema enforces the same taxonomy.

### Literacy family (dimensions: task-completion, code-correctness, doc-coverage)
Failure modes:
${literacyList}
Plus cross-cutting: ${commonList}

### MCP family (dimensions: mcp-behavior, input-validation, output-correctness, error-handling, security)
Failure modes:
${mcpList}
Plus cross-cutting: ${commonList}

### Knowledge-probe family (dimensions: knowledge-probe, factual-correctness, completeness, currency)
Failure modes:
${kpList}
Plus cross-cutting: ${commonList}

### Agent-harness family (dimensions: agent-harness, process-quality, agent-output, tool-usage)
Failure modes:
${agentList}
Plus cross-cutting: ${commonList}

## Confidence Calibration Rules

**CRITICAL:** When sampleSize < 10, you MUST set confidence.level = "low".

- sampleSize >= 30 → "high" is appropriate
- sampleSize >= 10 → "medium" is appropriate
- sampleSize < 10 → MUST use "low" (small-sample hedge required)

In your summary, reflect the confidence level: if "low", include language like "small sample (N=X) — re-run with broader dataset before acting".`;
