Unified command for adding specs one at a time. Supports both interactive wizard mode and direct CLI mode.
Key Features:
-y/--yes) for scripted usagebash$spec-add # Interactive wizard (all prompts) $spec-add --interactive # Explicit interactive wizard $spec-add "Use async/await instead of callbacks" # Direct mode (auto-detect type) $spec-add -y "No direct DB access" --type constraint # Auto-confirm, skip confirmation $spec-add --scope global --dimension personal # Create global personal spec (interactive) $spec-add --dimension specs --category exploration # Project spec in exploration category (interactive) $spec-add "Cache invalidation requires event sourcing" --type learning --category architecture
| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | rule | string | Yes (unless --interactive) | - | The rule, convention, or insight to add | | --type | enum | No | auto-detect | Type: convention, constraint, learning | | --category | string | No | auto-detect / general | Category for organization (see categories below) | | --dimension | enum | No | Interactive | specs (project) or personal | | --scope | enum | No | project | global or project (only for personal dimension) | | --interactive | flag | No | - | Launch full guided wizard for adding rules | | -y / --yes | flag | No | - | Auto-categorize and add without confirmation |
convention - Coding style preferences (goes to conventions section)
coding_style, naming_patterns, file_structure, documentationconstraint - Hard rules that must not be violated (goes to constraints section)
architecture, tech_stack, performance, securitylearning - Session-specific insights (goes to learnings array)
architecture, performance, security, testing, process, other--category)| Category | Use Case | Example Rules | |----------|----------|---------------| | general | Applies to all stages | "Use TypeScript strict mode" | | exploration | Code exploration, debugging | "Always trace the call stack before modifying" | | planning | Task planning, requirements | "Break down tasks into 2-hour chunks" | | execution | Implementation, testing | "Run tests after each file modification" |
Input Parsing:
|- Parse: rule text (positional argument, optional if --interactive)
|- Parse: --type (convention|constraint|learning)
|- Parse: --category (subcategory)
|- Parse: --dimension (specs|personal)
|- Parse: --scope (global|project)
|- Parse: --interactive (flag)
+- Parse: -y / --yes (flag)
Step 1: Parse Input
Step 2: Determine Mode
|- If --interactive OR no rule text -> Full Interactive Wizard (Path A)
+- If rule text provided -> Direct Mode (Path B)
Path A: Interactive Wizard
|- Step A1: Ask dimension (if not specified)
|- Step A2: Ask scope (if personal + scope not specified)
|- Step A3: Ask category (if not specified)
|- Step A4: Ask type (convention|constraint|learning)
|- Step A5: Ask content (rule text)
+- Continue to Step 3
Path B: Direct Mode
|- Step B1: Auto-detect type (if not specified) using detectType()
|- Step B2: Auto-detect category (if not specified) using detectCategory()
|- Step B3: Default dimension to 'specs' if not specified
+- Continue to Step 3
Step 3: Determine Target File
|- specs dimension -> .ccw/specs/coding-conventions.md or architecture-constraints.md
+- personal dimension -> ~/.ccw/personal/ or .ccw/personal/
Step 4: Validate and Write Spec
|- Ensure target directory and file exist
|- Check for duplicates
|- Append rule to appropriate section
+- Run ccw spec rebuild
Step 5: Display Confirmation
+- If -y/--yes: Minimal output
+- Otherwise: Full confirmation with location detailsjavascript// Parse arguments const args = "$ARGUMENTS" const argsLower = args.toLowerCase() // Extract flags const AUTO_YES = argsLower.includes('--yes') || argsLower.includes('-y') const isInteractive = argsLower.includes('--interactive') // Extract named parameters const hasType = argsLower.includes('--type') const hasCategory = argsLower.includes('--category') const hasDimension = argsLower.includes('--dimension') const hasScope = argsLower.includes('--scope') let type = hasType ? args.match(/--type\s+(\w+)/i)?.[1]?.toLowerCase() : null let category = hasCategory ? args.match(/--category\s+(\w+)/i)?.[1]?.toLowerCase() : null let dimension = hasDimension ? args.match(/--dimension\s+(\w+)/i)?.[1]?.toLowerCase() : null let scope = hasScope ? args.match(/--scope\s+(\w+)/i)?.[1]?.toLowerCase() : null // Extract rule text (everything before flags, or quoted string) let ruleText = args .replace(/--type\s+\w+/gi, '') .replace(/--category\s+\w+/gi, '') .replace(/--dimension\s+\w+/gi, '') .replace(/--scope\s+\w+/gi, '') .replace(/--interactive/gi, '') .replace(/--yes/gi, '') .replace(/-y\b/gi, '') .replace(/^["']|["']$/g, '') .trim() // Validate values if (scope && !['global', 'project'].includes(scope)) { console.log("Invalid scope.
