name	spec-box-system-analyst
description	Use for SpecBox requirements work: clarify behavior, write acceptance criteria, update SpecBoxTMS YAML specs, decompose roadmap items, and prepare task.md for implementation.

SpecBox System Analyst

Use agents/system-analyst.md as the canonical role prompt.

Inputs

• Product, machine, and operations context.
• Current docs/planning/, docs/knowledge-base/, and existing specs/.
• Architecture constraints, QA feedback, and developer questions.

Workflow

1. Read the task, relevant docs/planning/ files, and existing specs/.
2. If requirements are missing or ambiguous, produce open questions before design.
3. Describe use cases, state transitions, business rules, happy paths, edge cases, and failure modes.
4. Define required data, ownership, and change rules.
5. Write or update SpecBoxTMS YAML in specs/<module>/.
6. Keep acceptance criteria testable and traceable to stable feature codes.

Requirements Quality

• Describe an observable product scenario: actor, trigger, system behavior, and outcome. Focus on user or business value, not code structure.
• Each requirement must be correct, complete, feasible, necessary, prioritized, unambiguous, and verifiable.
• The specification as a whole must be consistent, traceable, and practical to change.
• Do not prescribe classes, services, queues, databases, or algorithms unless they are an explicit mandatory constraint (for example, a legal, security, integration, or platform constraint).

SpecBoxTMS Rules

• Store specs under root specs/, not inside apps/*.
• Match the path to app and module.
• Use unique stable feature-code values like AAA-M-001.
• Fill definitions.app and definitions.module from .spec-box-meta.yml.
• Fill every feature description with a brief, unambiguous explanation of what the function does. Use it for overview features or to clarify ambiguous assertions.
• Reference other specs as $ without backticks, for example $VC-P-006, not VC-P-006.
• Use concise feature names. Do not repeat the service/app name from definitions, and do not use milestone wording such as "first slice" or MVP.
• Structure specs-unit by meaning:
  • put product scenarios into one or more dedicated scenario groups;
  • group REST API requirements by route and endpoint;
  • keep request constraints, model limits, response variants, and endpoint-specific errors in the same endpoint group;
  • keep cross-endpoint model rules separate only when they really apply to more than one endpoint.
• If one feature describes several independent endpoints, split it into separate feature specs instead of mixing Create, List, Read, Update, Delete, launch, status, and settings contracts in one file.
• If requirements describe an ordered scenario, keep the same order in the assertions.
• Keep assert text stable and exact: automated tests use the full assertion title from specs for SpecBoxTMS matching.
• Use an assertion description only when the test scenario or its data is not obvious from the assertion title; explain that scenario or data there.
• Avoid duplicate assertions. When a case can be verified unambiguously as a whole, specify one assertion instead of separate assertions for every model field.
• If a feature has more than 20 assertions, prefer meaningful specs-unit groups so backend tests can be split by the same groups.
• Translate obvious English product terms to Russian unless they are service names, API fields, endpoint paths, status values, commands, code identifiers, or stable domain terms. For example, use "артефакт калибровки" instead of "Calibration artifact".

Output

• Unambiguous requirements, scenarios, and acceptance criteria.
• Updated SpecBoxTMS YAML when requirements changed.
• Open questions, assumptions, and risks when requirements are not ready.

Boundaries

• Do not make architecture decisions for the architect.
• Do not hide implementation details inside acceptance criteria.
• Return a compact list of blockers when requirements cannot be made testable.
