    "## What to Flag\n"
    "1. CONTRADICTION — requirements that conflict with each other\n"
    "2. AMBIGUITY — requirements where two reasonable interpretations would "
    "produce *incompatible* implementations\n"
    "3. CRITICAL GAPS — missing error handling that would cause crashes, data loss, "
    "or security issues\n"
    "4. INFEASIBILITY — things that cannot be built as described\n"
    "5. SPEC-ARCH MISMATCH — if AMD is provided, flag cases where the architecture "
    "contradicts or fails to cover spec requirements\n\n"
    "## What NOT to Flag\n"
    "- Implementation details the LLM can reasonably decide (algorithms, data structures, "
    "internal architecture)\n"
    "- Missing details that have standard or reasonably obvious solutions in {language}\n"
    "- Underspecification where any reasonable choice produces acceptable behavior\n"
    "- Behavior that can be inferred from the examples provided\n"
    "- Stylistic preferences (naming, formatting, code organization)\n"
    "- Things that would be documented in an Architecture file when no AMD is provided\n"
    "- Missing AMD — specs without architecture files are valid; "
    "the LLM will infer architecture\n\n"
    "## Severity Calibration\n"
    "- ERROR: Will cause *wrong* behavior — code won't match user intent\n"
    "- WARNING: Could cause wrong behavior depending on LLM interpretation\n"
    "- INFO: Worth clarifying but any reasonable implementation is acceptable\n\n"
    "## The Key Test\n"
    "Before flagging, ask: 'If two competent developers implemented this independently, "
    "would the ambiguity cause their implementations to be *incompatible* or produce "
    "*different user-visible behavior*?' If no, don't flag it.\n\n"

    "## What to Flag\n"
    "1. DEPENDENCY GAPS — Spec A depends on Spec B, but B doesn't provide "
    "something A's requirements clearly need\n"
    "2. CONTRACT MISMATCHES — Incompatible assumptions between specs about "
    "shared data types, error handling, or communication patterns\n"

    "## What NOT to Flag\n"

    "If audit findings are provided, account for them in your planning — "
    "avoid generating tasks that would hit known spec issues.\n\n"
    "Before finalizing, verify that your dependency ordering is valid: no task should "

    "5. Preserve the existing formatting style and markdown structure\n"
    "6. Do not change metadata fields (@id, @status, @priority, @depends, @spec) "
