# cli-view Specification
## Purpose
The `openspec view` command provides a comprehensive dashboard view of the OpenSpec project state, displaying specifications, changes, and progress metrics in a unified, visually appealing format to help developers quickly understand project status.
## Requirements
### Requirement: Dashboard Display
The system SHALL provide a `view` command that displays a dashboard overview of specs and changes.
#### Scenario: Basic dashboard display
- **WHEN** user runs `openspec view`
- **THEN** system displays a formatted dashboard with sections for summary, active changes, completed changes, and specifications
#### Scenario: No OpenSpec directory
- **WHEN** user runs `openspec view` in a directory without OpenSpec
- **THEN** system displays error message "✗ No openspec directory found"
### Requirement: Summary Section
The dashboard SHALL display a summary section with key project metrics.
#### Scenario: Complete summary display
- **WHEN** dashboard is rendered with specs and changes
- **THEN** system shows total number of specifications and requirements
- **AND** shows number of active changes in progress
- **AND** shows number of completed changes
- **AND** shows overall task progress percentage
#### Scenario: Empty project summary
- **WHEN** no specs or changes exist
- **THEN** summary shows zero counts for all metrics
### Requirement: Active Changes Display
The dashboard SHALL show active changes with visual progress indicators.
#### Scenario: Active changes ordered by completion percentage
- **WHEN** multiple active changes are displayed with progress information
- **THEN** list them sorted by completion percentage ascending so 0% items appear first
- **AND** treat missing progress values as 0% for ordering
- **AND** break ties by change identifier in ascending alphabetical order to keep output deterministic
### Requirement: Completed Changes Display
The dashboard SHALL list completed changes in a separate section.
#### Scenario: Completed changes listing
- **WHEN** there are completed changes (all tasks done)
- **THEN** system shows them with checkmark indicators in a dedicated section
#### Scenario: Mixed completion states
- **WHEN** some changes are complete and others active
- **THEN** system separates them into appropriate sections
### Requirement: Specifications Display
The dashboard SHALL display specifications sorted by requirement count.
#### Scenario: Specs listing with counts
- **WHEN** specifications exist in the project
- **THEN** system shows specs sorted by requirement count (descending) with count labels
#### Scenario: Specs with parsing errors
- **WHEN** a spec file cannot be parsed
- **THEN** system includes it with 0 requirement count
### Requirement: Visual Formatting
The dashboard SHALL use consistent visual formatting with colors and symbols.
#### Scenario: Color coding
- **WHEN** dashboard elements are displayed
- **THEN** system uses cyan for specification items
- **AND** yellow for active changes
- **AND** green for completed items
- **AND** dim gray for supplementary text
#### Scenario: Progress bar rendering
- **WHEN** displaying progress bars
- **THEN** system uses filled blocks (█) for completed portions and light blocks (░) for remaining
### Requirement: Error Handling
The view command SHALL handle errors gracefully.
#### Scenario: File system errors
- **WHEN** file system operations fail
- **THEN** system continues with available data and omits inaccessible items
#### Scenario: Invalid data structures
- **WHEN** specs or changes have invalid format
- **THEN** system skips invalid items and continues rendering
