specify-extend 2.2.1

Installation tool for spec-kit-extensions that works alongside specify init

spec-kit-extensions

11 production-tested workflows that extend spec-kit to cover the complete software development lifecycle.

What Is This?

spec-kit provides structured workflows for feature development (/speckit.specify → /speckit.plan → /speckit.tasks → /speckit.implement). These extensions add 11 additional workflows for the remaining ~75% of software development work:

Workflow Extensions (full spec-kit workflow with branch, specs, and templates)

• /speckit.workflows.bugfix - Fix bugs with regression-test-first approach
• /speckit.workflows.hotfix - Handle production emergencies with expedited process
• /speckit.workflows.enhance - Make minor enhancements with streamlined single-doc workflow
• /speckit.workflows.refactor - Improve code quality with metrics tracking
• /speckit.workflows.deprecate - Sunset features with phased 3-step rollout
• /speckit.workflows.modify - Modify existing features with automatic impact analysis
• /speckit.workflows.baseline - Establish project baseline and track all changes
• /speckit.workflows.cleanup - Validate and reorganize spec-kit artifacts

Command Extensions (provide commands without workflow structure)

• /speckit.workflows.review - Review completed work with structured feedback
• /speckit.workflows.phasestoissues - Create individual GitHub issues for each development phase
• /speckit.workflows.incorporate - Incorporate documents into workflows

Note: All commands also have short aliases (e.g., /speckit.bugfix instead of /speckit.workflows.bugfix).

Why Use These Extensions?

The Problem

With vanilla spec-kit, you get structure for ~25% of your work (new features), but the remaining 75% happens ad-hoc:

• Bugs: No systematic approach → regressions happen
• Feature changes: No impact analysis → breaking changes
• Code quality: No metrics → unclear if refactor helped
• Emergencies: No process → panic-driven development
• Feature removal: No plan → angry users

The Solution

These extensions bring spec-kit's structured approach to all development activities:

Activity	Without Extensions	With Extensions
New Feature	/speckit.specify workflow	Same
Project Baseline	Ad-hoc	/speckit.workflows.baseline with comprehensive docs
Bug Fix	Ad-hoc	/speckit.workflows.bugfix with regression tests
Minor Enhancement	Ad-hoc	/speckit.workflows.enhance with streamlined planning
Modify Feature	Ad-hoc	/speckit.workflows.modify with impact analysis
Refactor Code	Ad-hoc	/speckit.workflows.refactor with metrics
Production Fire	Panic	/speckit.workflows.hotfix with post-mortem
Remove Feature	Hope	/speckit.workflows.deprecate with 3-phase sunset
Codebase Cleanup	Manual	/speckit.workflows.cleanup with automation
Work Review	Inconsistent	/speckit.workflows.review with structured feedback
GitHub Issues	Manual	/speckit.workflows.phasestoissues with phase-level tracking

Quick Start

Prerequisites

• spec-kit installed from source (github.com/github/spec-kit) — requires version with extension support (v0.2.0+)
• AI coding agent (Claude Code, GitHub Copilot, Gemini CLI, Cursor, etc.)
• Git repository

Installation

Step 1: Initialize spec-kit (if not already done):

specify init --here --ai claude

Step 2: Install extensions (recommended):

# Install the CLI tool
pip install specify-extend
# or: uvx specify-extend --all

# Install all extensions
specify-extend --all

specify-extend --all is the recommended installation method until spec-kit natively supports alternate feature branch patterns (bugfix/, hotfix/, etc.). It:

1. Downloads and installs the extension via specify extension add
2. Patches spec-kit's common.sh to recognize extension branch patterns

Alternative: Native spec-kit install (advanced — does not patch branch patterns):

# Install extension only (no branch pattern support)
specify extension add workflows --from https://github.com/pradeepmouli/spec-kit-extensions/archive/refs/heads/main.zip

# Then manually patch branch patterns
specify-extend --patch

Verify Installation

# Check extension is installed
specify extension list

# Should show:
#   Spec Kit Workflow Extensions (v3.2.0)
#   Commands: 11 | Status: Enabled

# Try a command:
/speckit.workflows.bugfix "test bug"
# Or use the alias:
/speckit.bugfix "test bug"

Post-Installation Structure

After installation, your project will have:

your-project/
├── .specify/
│   ├── extensions/
│   │   └── workflows/           # Extension install directory
│   │       ├── extension.yml    # Extension manifest

Usage

Quick Decision Tree

Starting with spec-kit?
└─ Use /speckit.workflows.baseline to establish project context

Building something new?
├─ Major feature → /speckit.specify "description"
└─ Minor enhancement → /speckit.workflows.enhance "description"

Fixing broken behavior?
├─ Production emergency → /speckit.workflows.hotfix "incident"
└─ Non-urgent bug → /speckit.workflows.bugfix "bug description"

Changing existing feature?
├─ Adding/modifying behavior → /speckit.workflows.modify 014 "change"
└─ Improving code quality → /speckit.workflows.refactor "improvement"

Removing a feature?
└─ /speckit.workflows.deprecate 014 "reason"

Reviewing completed work?
└─ /speckit.workflows.review [task-id]

Creating GitHub issues?
└─ /speckit.workflows.phasestoissues

Example: Fix a Bug

# Step 1: Create bug report
/speckit.workflows.bugfix "profile form crashes when submitting without image"
# Creates: bug-report.md with initial analysis

# Step 2: Investigate and update bug-report.md with root cause

# Step 3: Create fix plan
/speckit.plan

# Step 4: Break down into tasks
/speckit.tasks

# Step 5: Execute fix
/speckit.implement

Example: Modify Existing Feature

# Step 1: Create modification spec with impact analysis
/speckit.workflows.modify 014 "make profile fields optional"
# Creates: modification-spec.md + impact-analysis.md

# Step 2: Review impact analysis

# Step 3-5: Plan, tasks, implement (same as above)

FAQ

Do I need to use all 11 workflows?

No! Use only what you need. Common combinations:

• Minimal: Just bugfix (most teams need this)
• Standard: bugfix + enhance + modify (covers most scenarios)
• Complete: All 11 workflows (full lifecycle coverage)

Why use specify-extend --all instead of specify extension add?

specify-extend --all additionally patches spec-kit's common.sh to support extension branch patterns (bugfix/, hotfix/, refactor/, etc.). Without this patch, spec-kit's branch validation will reject these branch names. Once spec-kit natively supports alternate branch patterns, specify extension add alone will be sufficient.

Can I customize the workflows?

Yes! After installation, all files are in .specify/extensions/workflows/. Edit templates, commands, or scripts to suit your needs.

Do these work without Claude Code?

Yes! The workflows are agent-agnostic. They work with any AI agent that supports spec-kit.
