# Feature Specification: [FEATURE NAME]
|
|
|
|
**Feature Branch**: `[###-feature-name]`
|
|
**Created**: [DATE]
|
|
**Status**: Draft
|
|
**Input**: User description: "$ARGUMENTS"
|
|
|
|
## User Scenarios & Testing *(mandatory)*
|
|
|
|
<!--
|
|
IMPORTANT: User stories should be PRIORITIZED as user journeys ordered by importance.
|
|
Each user story/journey must be INDEPENDENTLY TESTABLE - meaning if you implement just ONE of them,
|
|
you should still have a viable MVP (Minimum Viable Product) that delivers value.
|
|
|
|
Assign priorities (P1, P2, P3, etc.) to each story, where P1 is the most critical.
|
|
Think of each story as a standalone slice of functionality that can be:
|
|
- Developed independently
|
|
- Tested independently
|
|
- Deployed independently
|
|
- Demonstrated to users independently
|
|
-->
|
|
|
|
### User Story 1 - [Brief Title] (Priority: P1)
|
|
|
|
[Describe this user journey in plain language]
|
|
|
|
**Why this priority**: [Explain the value and why it has this priority level]
|
|
|
|
**Independent Test**: [Describe how this can be tested independently - e.g., "Can be fully tested by [specific action] and delivers [specific value]"]
|
|
|
|
**Acceptance Scenarios**:
|
|
|
|
1. **Given** [initial state], **When** [action], **Then** [expected outcome]
|
|
2. **Given** [initial state], **When** [action], **Then** [expected outcome]
|

### User Story 2 - [Brief Title] (Priority: P2)

|
**Why this priority**: [Explain the value and why it has this priority level]
|
|
|
|
**Independent Test**: [Describe how this can be tested independently]
|
|

|
**Acceptance Scenarios**:

### User Story 3 - [Brief Title] (Priority: P3)
|
|
|
|
[Describe this user journey in plain language]
|
|
|
|
**Why this priority**: [Explain the value and why it has this priority level]
|
|
|
|
**Independent Test**: [Describe how this can be tested independently]
|

|
|
|
|
[Add more user stories as needed, each with an assigned priority]

|
### Edge Cases
|
|
|
|
<!--
|
|
ACTION REQUIRED: The content in this section represents placeholders.
|
|
Fill them out with the right edge cases.
|
|
-->
|
|
|
|
- How does the rename plan handle conflicting target names or read-only files?
|
|
- What is the expected behavior when the `.renamer` ledger is missing, corrupted, or out of sync?
|
|
- How are case-only renames or Unicode normalization differences managed across platforms?
|
|
- What feedback is provided when an extension filter yields zero matches or contains invalid tokens?
|
|
|
|
## Requirements *(mandatory)*
|
|
|
|
<!--
|
|
ACTION REQUIRED: The content in this section represents placeholders.
|
|
Fill them out with the right functional requirements.
|
|
-->
|
|
|
|
### Functional Requirements
|
|
|
|
- **FR-001**: CLI MUST generate a deterministic preview of all pending renames before execution.
|
|
- **FR-002**: Users MUST confirm the preview (or abort) prior to any filesystem changes.
|
|
- **FR-003**: The tool MUST append every confirmed batch to the `.renamer` ledger with sufficient metadata for undo.
|
|
- **FR-004**: Users MUST be able to undo the most recent batch safely, even across process restarts.
|
|
- **FR-005**: CLI MUST support directory targeting (`-d`) and optional recursive traversal (`-r`) with clear scope boundaries.
|
|
- **FR-006**: CLI MUST accept an extension filter flag (`-e`) that parses `.`-prefixed, `|`-delimited extensions and applies the filter consistently across preview, execute, and undo flows.
|
|
|
|
*Example of marking unclear requirements:*
|
|
|
|
- **FR-007**: CLI MUST support additional rename rule `[RULE_NAME]` [NEEDS CLARIFICATION: inputs/outputs not defined]
|
|
- **FR-008**: CLI MUST expose automation-friendly output [NEEDS CLARIFICATION: format (JSON, plain text) undecided]
|
|
|
|
### Key Entities *(include if feature involves data)*
|
|
|
|
- **RenameBatch**: Represents a single preview/execute cycle; attributes include rules applied, timestamp, working directory, and file mappings.
|
|
- **RuleDefinition**: Captures configuration for a rename rule (inputs, validations, dependencies) without binding to implementation.
|
|
|
|
## Success Criteria *(mandatory)*
|
|
|
|
<!--
|
|
ACTION REQUIRED: Define measurable success criteria.
|
|
These must be technology-agnostic and measurable.
|
|
-->
|
|
|
|
### Measurable Outcomes
|
|
|
|
- **SC-001**: [Measurable metric, e.g., "Users can complete account creation in under 2 minutes"]
|
|
- **SC-002**: [Measurable metric, e.g., "System handles 1000 concurrent users without degradation"]
|
|
- **SC-003**: [User satisfaction metric, e.g., "90% of users successfully complete primary task on first attempt"]
|
|
- **SC-004**: [Business metric, e.g., "Reduce support tickets related to [X] by 50%"]
