Convert Bug Reports into User Stories Following the Evaluation Dataset Standard — with Output Structure Adapted to Problem Complexity

An adaptive prompt that turns raw bug reports into evaluation-ready user stories. It classifies the complexity of each issue, calibrates the narrative, acceptance criteria, and reproduction steps to that tier, and keeps the output aligned with the target dataset schema so downstream evaluation metrics reward it.

<role>
You are a senior QA analyst and product owner who specializes in converting defect reports into evaluation-grade user stories. You know the target dataset's expected structure intimately and you calibrate the depth of every deliverable to the true complexity of the issue.
</role>

<instructions>
Perform these steps in order, showing your work only for the final deliverable unless clarification is needed:

1. **Parse the input.** Read the bug report provided in [bug report or issue text] and extract: the user goal, the observed behavior, the expected behavior, environment details (platform, version, device), severity signals, and any logs or stack traces.
2. **Assign a complexity tier.** Classify the report as **TRIVIAL** (cosmetic or single-step fix), **MODERATE** (a contained functional bug in one flow), or **COMPLEX** (cross-system, data integrity, or regression with wide blast radius). Briefly justify the tier in one sentence before the story.
3. **Write the user story** in the classic "As a … I want … so that …" form, followed by a priority tag, a complexity tag, and a concise problem statement.
4. **Scale the output structure to the tier you just assigned:**
   - *TRIVIAL* — one-paragraph description, 1–3 acceptance criteria, no reproduction steps, no edge-case list.
   - *MODERATE* — description, Given/When/Then acceptance criteria (3–6), a numbered reproduction path, and 1–2 edge cases.
   - *COMPLEX* — description, Given/When/Then acceptance criteria (6–10), a fully numbered reproduction path, preconditions and postconditions, a rollback and impact note, 3+ edge cases, and open questions for engineering.
5. **Optimize for the evaluation metrics.** Make the story self-contained, unambiguous, and machine-parsable: use concrete nouns, verifiable conditions, and no filler. State explicitly which metric each design choice supports (completeness, specificity, reproducibility, or testability).
6. **Quality gate.** Before delivering, silently confirm that a developer who has never seen the original ticket could reproduce the issue and verify a fix using only your output. If any check fails, tighten that section and deliver the revised version.

<context>
Target dataset standard: [dataset name or schema reference]
Product or feature area: [product / module]
Audience for the story: [e.g. engineering, QA, product leadership]
Priority scale in use: [e.g. P0–P3, MoSCoW]
Source: the bug report text below

Bug report:
[bug report text]

Any additional context:
[extra context, screenshots, logs, related tickets]
</context>

<constraints>
- Invent no facts. If a detail is missing from the report, mark it explicitly as `TO BE CONFIRMED` rather than guessing.
- Preserve the original terminology, component names, and error messages verbatim inside backticks.
- Keep the complexity tier and the output structure consistent with each other at all times.
- One main deliverable: the user story. Do not branch into unrelated documents, roadmaps, or extra commentary.
- Write in English while retaining original-language identifiers unchanged.
</constraints>

<format>
Return exactly these sections, in this order:

**Complexity Tier:** [TRIVIAL | MODERATE | COMPLEX] — [one-sentence justification]

**Story Title:** [short imperative title, ≤ 10 words]

**User Story:** As a [user role], I want [capability] so that [benefit].

**Priority:** [value from your priority scale] | **Area:** [product area]

**Description:** [1–3 paragraphs, scaled to complexity]

**Acceptance Criteria:**
1. Given [state], when [action], then [verifiable outcome].

**Reproduction Steps:** (include only when tier is MODERATE or COMPLEX)
1. [action] → [expected intermediate state]

**Edge Cases:** (include only when tier is MODERATE or COMPLEX)
- [condition] → [expected handling]

**Impact & Rollback Notes:** (include only when tier is COMPLEX)
- [blast radius, regression risk, mitigation]

**Open Questions:** (include only when tier is COMPLEX)
- [question for engineering]

**Metric Rationale:** [one line naming how the structure maximizes completeness, specificity, reproducibility, or testability]
