Spec Kitty

Spec-Driven Development for AI coding agents

Spec Kitty is an open-source CLI workflow for spec-driven development with AI coding agents. It helps teams turn product intent into implementation with a repeatable path: spec -> plan -> tasks -> spec-kitty next (agent loop) -> review -> merge.

Why teams use it

AI coding workflows often break down on larger features:

Requirements and design decisions drift over long agent sessions
Parallel work is hard to coordinate across branches
Review and acceptance criteria become inconsistent from one feature to the next

Spec Kitty addresses this with repository-native artifacts, work package workflows, and lane-aware git worktree isolation.

Who it's for

Project Owners who need explicit approval boundaries and outcome accountability
External Tech Lead Evaluators assessing delivery predictability and adoption fit
External Architect Evaluators evaluating governance durability and boundary clarity
External Product Manager Evaluators validating intent-to-delivery traceability
Lead Developers coordinating implementation quality and handoffs
Maintainers preserving operational consistency across features and agents

Stakeholder Value Proposition

🚀 What You Get on `main` (`3.2.0a4`)

Capability	What Spec Kitty provides
Spec-driven artifacts	Generates and maintains mission briefs, ticket context, `spec.md`, `plan.md`, `wps.yaml`, and `tasks.md` in repository-native locations
Ticket and brief intake	Seeds `/spec-kitty.specify` from `spec-kitty intake` or `spec-kitty mission create --from-ticket <provider:KEY>`
Work package execution	Uses canonical lifecycle lanes (`planned`, `claimed`, `in_progress`, `for_review`, `in_review`, `approved`, `done`, `blocked`, `canceled`) with `doing` as UI alias for `in_progress`
Parallel implementation model	Creates isolated git worktrees under `.worktrees/`; every mission executes through swim-lane worktrees, with exactly one worktree per computed swim lane
Governed operator workflows	Routes operator requests through `spec-kitty do`, `advise`, and `ask`, with durable invocation records and local audit queries via `invocations list`
Live project visibility	Local dashboard for kanban and mission progress (`spec-kitty dashboard`)
Hosted sync and Teamspace routing	Browser auth, provider-aware tracker reads, checkout routing diagnostics, repository sharing, and Private Teamspace-aware sync controls
Charter and compatibility governance	Harness-owned charter synthesis, provenance reporting, `charter bundle validate`, `charter resynthesize --list-topics`, and `doctor shim-registry`
Review resilience	Persisted versioned review artifacts, focused fix prompts, dirty-state classification, and arbiter checklists
Execution resilience	Interrupted merge recovery (`merge --resume`), crash recovery (`implement --recover`), stale-claim diagnostics, sparse-checkout repair, and stricter release validation
Multi-agent support	15 AI integrations: 13 project-local slash/prompt surfaces plus Codex CLI and Mistral Vibe via shared Agent Skills

📊 Project Snapshot

Current stable release line: v3.1.x (current stable release: 3.1.6 on GitHub Releases and PyPI)

Current main development version: 3.2.0a4

Current main highlights:

Brief-first and ticket-first intake — spec-kitty intake ingests external plans into .kittify/mission-brief.md, and spec-kitty mission create --from-ticket <provider:KEY> seeds tracker context before /spec-kitty.specify
Governed profile routing with durable audit trails — spec-kitty do, advise, and ask open invocation records, profile-invocation complete closes them, and invocations list exposes the local audit log
Hosted tracker reads and Teamspace-aware sync — issue-search, tracker discover / tracker list-tickets, encrypted local auth sessions, sync routes, repository sharing, and Private Teamspace routing tighten the SaaS workflow
Charter synthesis is harness-owned and inspectable — generated-artifact adapters, charter status --provenance, charter resynthesize --list-topics, bundle validation, and stronger neutrality rules make synthesis auditable
Compatibility and release governance are stricter — doctor shim-registry, mutation-testing guidance, shared-package drift checks, SBOM-attached prereleases, and safer publish validation harden upgrades and releases
Review and runtime recovery keep improving — sparse-checkout defenses, offline/auth refresh fixes, provider-aware tracker readiness, action-routing hardening, and post-merge fixes to the profile-invocation flow reduce recovery work
15 AI integrations are supported — 13 project-local slash/prompt surfaces plus Codex CLI and Mistral Vibe via shared Agent Skills, with Kiro fully documented and legacy q retained for compatibility

📌 Release Channels

Spec Kitty currently ships stable 3.1.x releases while main carries the active 3.2.0a4 prerelease/dev line. The former 1.x line is deprecated and lives on 1.x-maintenance for maintenance-only fixes.

Source	Version	Status	Install
PyPI / GitHub Releases	3.1.6	Current stable line	`pip install spec-kitty-cli`
main	3.2.0a4	Active prerelease / development line	Install from a source checkout or a published prerelease tag
1.x-maintenance	1.x	Deprecated, maintenance-only	Install from a pinned maintenance tag or source checkout

For users: install the stable line from PyPI with pip install spec-kitty-cli. For testers following main: use a source checkout or published prerelease builds to get the intake, profile-invocation, hosted tracker-read, and Teamspace-routing work that is newer than stable 3.1.x. For existing 3.0.x users: upgrade to 3.1.x and run spec-kitty upgrade in each project — the charter rename, mission identity, and prompt-neutrality migrations remain automatic. For existing 1.x or 2.x users: migrate to 3.1.x; 1.x-maintenance is maintenance-only and will no longer publish new PyPI releases.

🤝 Multi-Agent Coordination for AI Coding

Run multi-agent delivery with an external orchestrator while keeping workflow state and guardrails in spec-kitty. Core CLI orchestration is exposed as spec-kitty orchestrator-api; there is no in-core spec-kitty orchestrate shim.

Terminology note:

Mission Type = reusable blueprint
Mission = concrete tracked item
Mission Run = runtime/session instance
--mission is the canonical flag in 3.1.x; --feature is retained only as a hidden deprecated alias

# Verify host contract
spec-kitty orchestrator-api contract-version --json

# Use the reference external orchestrator
spec-kitty-orchestrator orchestrate --mission 034-my-mission --dry-run
spec-kitty-orchestrator orchestrate --mission 034-my-mission

    Note over Dashboard: Real-time updates<br/>No branch switching

Key Benefits:

🔀 Parallel execution - Multiple WPs simultaneously
🌳 Worktree isolation - Each swim lane gets one worktree, and sequential WPs in the same swim lane reuse it
👀 Full visibility - Dashboard shows who's doing what
🔒 Security boundary - Orchestration policy and transitions are validated at the host API boundary

📊 Real-Time Dashboard

Spec Kitty includes a live dashboard that automatically tracks your feature development progress. View your kanban board, monitor work package status, and see which agents are working on what—all updating in real-time as you work.

Spec Kitty Dashboard - Kanban Board View

Kanban board showing work packages across all lanes with agent assignments

Feature overview with completion metrics and available artifacts

Start the dashboard when you want it with /spec-kitty.dashboard or spec-kitty dashboard. The CLI starts the correct project dashboard if it is not already running, lets you request a specific port with --port <PORT> (defaults to auto-select from 3000-5000), can open the browser for you with --open, and stops the instance cleanly with --kill.

Key Features:

📋 Kanban Board: Visual workflow across canonical lifecycle lanes (including blocked and canceled) with Doing rendered as in_progress
📈 Progress Tracking: Real-time completion percentages and task counts
👥 Multi-Agent Support: See which AI agents are working on which tasks
📦 Artifact Status: Track specification, plan, tasks, and other deliverables
🔄 Live Updates: Dashboard refreshes automatically as you work

Kanban Workflow Automation

Work packages flow through automated quality gates using the canonical 2.x lifecycle FSM. Agents move tasks between lanes, and the dashboard tracks state transitions in real-time.

Lane terminology follows the glossary: see glossary/contexts/orchestration.md#lane.

🚀 Getting Started: Complete Workflow

New to Spec Kitty? Here's the complete lifecycle from zero to shipping features:

Phase 1: Install & Initialize (Terminal)

# 1. Install the CLI
pip install spec-kitty-cli
# or
uv tool install spec-kitty-cli

# 2. Initialize your project
spec-kitty init my-project --ai claude

# 3. Verify setup (optional)
cd my-project
spec-kitty verify-setup  # Checks that everything is configured correctly

# 4. View your dashboard
spec-kitty dashboard  # Opens http://localhost:3000-5000

What just happened:

✅ Created project-local command or prompt files for the selected integrations, or shared Agent Skills under .agents/skills/ for Codex / Vibe
✅ Created .kittify/ with templates, scripts, and mission scaffolding
✅ Prepared the project for verification, mission creation, and on-demand dashboard use
✅ Wrote project files only — spec-kitty init does not initialize Git for you

🔄 Upgrading Existing Projects

Important: If you've upgraded spec-kitty-cli via pip/uv, run spec-kitty upgrade in each of your projects to apply structural migrations.

Quick Upgrade

cd your-project
spec-kitty upgrade              # Upgrade to current version

What Gets Upgraded

The upgrade command automatically migrates your project structure across versions:

Version	Migration
0.10.9	Repair broken templates with bash script references (#62, #63, #64)
0.10.8	Move memory/ and AGENTS.md to .kittify/
0.10.6	Simplify implement/review templates to use workflow commands
0.10.2	Update slash commands to Python CLI and flat structure
0.10.0	Remove bash scripts, migrate to Python CLI
0.9.1	Complete lane migration + normalize frontmatter
0.9.0	Flatten task lanes to frontmatter-only (no directory-based lanes)
0.8.0	Remove active-mission (missions now per-feature)
0.7.3	Update scripts for worktree feature numbering
0.6.7	Ensure software-dev and research missions present
0.6.5	Rename commands/ → command-templates/
0.5.0	Install encoding validation git hooks
0.4.8	Add supported agent tooling directories to `.gitignore`
0.2.0	Rename .specify/ → .kittify/ and /specs/ → /kitty-specs/

Run spec-kitty upgrade --verbose to see which migrations apply to your project.

Upgrade Options

# Preview changes without applying
spec-kitty upgrade --dry-run

# Show detailed migration information
spec-kitty upgrade --verbose

# Upgrade to specific version
spec-kitty upgrade --target 0.6.5

# Skip worktree upgrades (main project only)
spec-kitty upgrade --no-worktrees

# JSON output for CI/CD integration
spec-kitty upgrade --json

When to Upgrade

Run spec-kitty upgrade after:

Installing a new version of spec-kitty-cli
Cloning a project that was created with an older version
Seeing "Unknown mission" or missing slash commands

The upgrade command is idempotent - safe to run multiple times. It automatically detects your project's version and applies only the necessary migrations.

Phase 2: Start Your AI Agent (Terminal)

# Launch your chosen AI coding agent
claude   # For Claude Code
# or
gemini   # For Gemini CLI
# or
code     # For GitHub Copilot / Cursor

Verify slash commands loaded: Type /spec-kitty and you should see autocomplete with all 13 commands.

Phase 3: Establish Project Principles (In Agent)

Still in the repository root checkout - Start with your project's governing principles:

/spec-kitty.charter

Create principles focused on code quality, testing standards,
user experience consistency, and performance requirements.

What this creates:

.kittify/memory/charter.md - Your project's architectural DNA
These principles will guide all subsequent development
Missions do not have separate charters; the project charter is the single source of truth

Phase 4: Create Your First Feature (In Agent)

Now begin the feature development cycle:

Optional before /spec-kitty.specify:

Ingest an external planning document with spec-kitty intake path/to/plan.md or spec-kitty intake --auto
Seed the workflow from a tracker ticket with spec-kitty mission create --from-ticket linear:PRI-42

4a. Define WHAT to Build

/spec-kitty.specify

Build a user authentication system with email/password login,
password reset, and session management. Users should be able to
register, login, logout, and recover forgotten passwords.

What this does:

Creates kitty-specs/auth-system/spec.md with user stories and mints a canonical mission_id (ULID) in meta.json
Enters discovery interview - Answer questions before continuing!
All planning happens in the repository root checkout (worktrees created later during implementation)
The mission target branch defaults to your current branch unless you explicitly choose another one

Note: Mission identity is a ULID (mission_id in meta.json). The three-digit numeric prefix (e.g. 001-auth-system) is display-only and is only assigned at merge time. Branches and worktrees use the mission's mid8 (first 8 chars of the ULID) for collision-free naming. See the mission identity migration runbook.

⚠️ Important: Continue in the same session - no need to change directories!

4b. Define HOW to Build (In the Repository Root Checkout)

/spec-kitty.plan

Use Python FastAPI for backend, PostgreSQL for database,
JWT tokens for sessions, bcrypt for password hashing,
SendGrid for email delivery.

What this creates:

kitty-specs/001-auth-system/plan.md - Technical architecture
kitty-specs/001-auth-system/data-model.md - Database schema
kitty-specs/001-auth-system/contracts/ - API specifications
Enters planning interview - Answer architecture questions!

4c. Optional: Research Phase

/spec-kitty.research

Investigate best practices for password reset token expiration,
JWT refresh token rotation, and rate limiting for auth endpoints.

What this creates:

kitty-specs/001-auth-system/research.md - Research findings
Evidence logs for decisions made

4d. Break Down Into Tasks

/spec-kitty.tasks

What this creates:

kitty-specs/001-auth-system/tasks.md - Kanban checklist
kitty-specs/001-auth-system/tasks/WP01.md - Work package prompts (flat structure)
Up to 10 work packages ready for implementation

Check your dashboard: You'll now see tasks in the planned lane.

Phase 5: Implement Features (Agent Loop)

5a. Execute Implementation

spec-kitty next --agent <agent> --mission <slug>

What this does:

Returns the next action for the mission (implement, review, decide) based on current WP states
Your agent invokes spec-kitty agent action implement <WP> --agent <name> per the returned action
Each call advances the WP through planned → in_progress → for_review → approved
Repeat until all work packages reach approved, then merge

Repeat until all work packages are done!

5b. Review Completed Work

/spec-kitty.review

What this does:

Auto-detects first WP with lane: "for_review" (or specify WP ID)
Moves review execution to lane: "in_progress" (displayed as "Doing") and shows the prompt
Agent reviews code and provides feedback or approval
Shows commands to move to lane: "done" (passed) or lane: "planned" (changes needed)

Phase 6: Accept & Merge

6a. Validate Feature Complete

/spec-kitty.accept

What this does:

Verifies all WPs have lane: "done"
Checks metadata and activity logs
Confirms no NEEDS CLARIFICATION markers remain
Records acceptance timestamp

6b. Merge to the Target Branch

/spec-kitty.merge --push

What this does:

Switches to the mission's target branch
Merges feature branch
Pushes to remote (if --push specified)
Cleans up worktree
Deletes feature branch

🎉 Feature complete! Return to the repository root checkout and start your next feature with /spec-kitty.specify

🔒 Agent Directory Best Practices

Important: Agent directories (.claude/, .codex/, .gemini/, etc.) should NEVER be committed to git.

Why?

These directories may contain:

Authentication tokens and API keys
User-specific credentials (auth.json)
Session data and conversation history

Automatic Protection

Spec Kitty automatically protects you with multiple layers:

During spec-kitty init:

✅ Adds supported agent directories to .gitignore
✅ Creates .claudeignore to optimize AI scanning (excludes .kittify/ templates)

Worktree Charter Sharing: When creating execution workspaces, Spec Kitty uses symlinks to share the charter:

.worktrees/my-feature-01J6XW9K-lane-a/.kittify/memory -> ../../../../.kittify/memory

This ensures all work packages follow the same project principles.

What Gets Committed?

✅ DO commit:

.kittify/templates/ - Command templates (source)
.kittify/missions/ - Mission workflows
.kittify/memory/charter.md - Project principles
.gitignore - Protection rules

❌ NEVER commit:

.claude/, .gemini/, .cursor/, etc. - Agent runtime directories
Any auth.json or credentials files

See AGENTS.md for complete guidelines.

📚 Terminology

Spec Kitty differentiates between the project that holds your entire codebase, the features you build within that project, and the mission that defines your workflow. Use these definitions whenever you write docs, prompts, or help text.

For glossary-first terminology (including semantic-integrity rules), see glossary/README.md.

Project

Definition: The entire codebase (one Git repository) that contains all missions, features, and .kittify/ automation.

Examples:

"spec-kitty project" (this repository)
"priivacy_rust project"
"my-agency-portal project"

Usage: Projects are initialized once with spec-kitty init. A project contains:

One active mission at a time
Multiple features (each with its own spec/plan/tasks)
Shared automation under .kittify/

Commands: Initialize with spec-kitty init for the current directory by default (or pass spec-kitty init my-project to create a project directory).

Feature

Definition: A single unit of work tracked by Spec Kitty. Every feature has its own spec, plan, tasks, and one or more swim-lane worktrees.

Mission identity (as of mission 083): A mission's canonical machine identity is mission_id — a ULID minted at creation and immutable for the lifetime of the mission. The three-digit mission_number prefix shown in directory names is display-only metadata and is assigned at merge time. Selectors use mission_id, mid8 (first 8 chars of the ULID), or mission_slug; ambiguous handles return a structured error. See the mission identity migration runbook.

Examples:

"001-auth-system feature"
"005-refactor-mission-system feature" (this document)
"042-dashboard-refresh feature"

Structure:

Specification: /kitty-specs/<human-slug>/spec.md (directory listing shows NNN-<human-slug> once mission_number is assigned at merge)
Plan: /kitty-specs/<human-slug>/plan.md
Tasks: /kitty-specs/<human-slug>/tasks.md
Implementation: swim-lane worktrees such as .worktrees/<human-slug>-<mid8>-lane-a/, .worktrees/<human-slug>-<mid8>-lane-b/, and so on (e.g. .worktrees/my-feature-01J6XW9K-lane-a/)

Lifecycle:

/spec-kitty.specify – Create the feature and its branch
/spec-kitty.plan – Document the technical design
/spec-kitty.tasks – Break work into packages
spec-kitty next – Drive the agent loop; your agent calls spec-kitty agent action implement per WP
/spec-kitty.review – Peer review
/spec-kitty.accept – Validate according to gates
/spec-kitty.merge – Merge and clean up

Commands: Always create features with /spec-kitty.specify.

Compatibility note: In current 2.x, feature slugs remain the practical artifact key for kitty-specs/ and worktrees.

Mission

Definition: A domain adapter that configures Spec Kitty (workflows, templates, validation). Missions are project-wide; all features in a project share the same active mission.

Examples:

"software-dev mission" (ship software with TDD)
"research mission" (conduct systematic investigations)
"writing mission" (future workflow)

What missions define:

Workflow phases (e.g., design → implement vs. question → gather findings)
Templates (spec, plan, tasks, prompts)
Validation rules (tests pass vs. citations documented)
Path conventions (e.g., src/ vs. research/)

Scope: Entire project. In current 2.x, mission is selected at init and remains fixed for the project lifecycle.

Runtime note: Mission-run identity (mission_id / mission_run_id) is the preferred runtime collaboration scope when available.

Commands:

Select at init: spec-kitty init my-project --mission research
Inspect: spec-kitty mission current / spec-kitty mission list

Quick Reference

Term	Scope	Example	Key Command
Project	Entire codebase	"spec-kitty project"	`spec-kitty init my-project`
Feature	Unit of work	"001-auth-system feature"	`/spec-kitty.specify "auth system"`
Mission	Workflow adapter	"research mission"	`spec-kitty init --mission research`

Common Questions

Q: What's the difference between a project and a feature?
A project is your entire git repository. A feature is one unit of work inside that project with its own spec/plan/tasks.

Q: Can I have multiple missions in one project?
Only one mission is active at a time in current 2.x. Select it during spec-kitty init.

Q: Should I create a new project for every feature?
No. Initialize a project once, then create as many features as you need with /spec-kitty.specify.

Q: What's a task? Tasks (T001, T002, etc.) are subtasks within a feature's work packages. They are not separate features or projects.

🤖 Supported AI Tools

Spec Kitty integrates with 15 AI tools. Thirteen tools receive project-local slash commands or prompt files written to an agent-specific directory (for example .claude/commands/ or .kiro/prompts/). Two tools — Codex CLI and Mistral Vibe — use the Agent Skills pipeline: Spec Kitty installs shared skills under .agents/skills/spec-kitty.<command>/, and Vibe also registers that shared root through project-local .vibe/config.toml skill_paths.

`<project-name>`	Argument	Name for your new project directory. Omit it, or pass `.`, to initialize the current directory.
`--ai`	Option	Comma-separated AI assistant keys. Current examples include `claude`, `codex`, `gemini`, `cursor`, `qwen`, `opencode`, `windsurf`, `kilocode`, `auggie`, `roo`, `copilot`, `q`, `kiro`, `antigravity`, and `vibe`.
`--non-interactive`, `--yes`	Flag	Run without prompts. Suitable for CI/CD and automation; `--ai` is required in this mode.

spec-kitty init creates project files only. It does not initialize Git, does not create commits, and missions are selected later during /spec-kitty.specify.

Examples

# Basic initialization in current directory (default)
spec-kitty init --ai claude

# Basic project initialization in a new directory
spec-kitty init my-project

# Initialize with specific AI assistant
spec-kitty init my-project --ai claude

# Initialize with Cursor support
spec-kitty init my-project --ai cursor

# Initialize with Windsurf support
spec-kitty init my-project --ai windsurf

# Initialize in current directory
spec-kitty init . --ai copilot

# Initialize multiple agents in one pass
spec-kitty init my-project --ai claude,codex

# Non-interactive setup for automation
spec-kitty init my-project --ai gemini --non-interactive

# Use a local template checkout during Spec Kitty development
SPEC_KITTY_TEMPLATE_ROOT=/path/to/spec-kitty spec-kitty init my-project --ai claude

# Check system requirements
spec-kitty verify-setup --diagnostics

`spec-kitty upgrade` Options

Option	Description
`--dry-run`	Preview changes without applying them
`--force`	Skip confirmation prompts

spec-kitty agent mission check-prerequisites – Validate project setup and mission context
spec-kitty agent mission setup-plan – Initialize the plan template for a mission
spec-kitty agent context update – Update agent context files
spec-kitty agent mission accept – Run acceptance workflow
spec-kitty agent mission merge – Merge the mission branch and clean up

Task Workflow:

spec-kitty agent action implement <id> --agent __AGENT__ – Advance planned/claimed → in_progress → for_review automatically
spec-kitty agent action review <id> --agent __AGENT__ – Advance for_review → in_progress → planned/done automatically
spec-kitty agent tasks list-tasks – List all tasks grouped by lane
spec-kitty agent tasks mark-status <id> --status <status> – Mark task status
spec-kitty agent tasks add-history <id> --note <message> – Add activity log entry

Available Slash Commands

After running spec-kitty init, your AI coding agent will have access to these slash commands for structured development.

📋 Quick Reference: See the command order flowchart above for a visual workflow guide.

Core Commands (In Recommended Order)

Workflow sequence for spec-driven development:

#	Command	Description
1	`/spec-kitty.charter`	(First in repository root checkout) Create or update project governing principles and development guidelines
2	`/spec-kitty.specify`	Define what you want to build (requirements and user stories; creates planning artifacts in the repository root checkout)
3	`/spec-kitty.plan`	Create technical implementation plans with your chosen tech stack
4	`/spec-kitty.research`	Run Phase 0 research scaffolding to populate research.md, data-model.md, and evidence logs
5	`/spec-kitty.tasks`	Generate actionable task lists and work package prompts in flat tasks/ directory
6	`spec-kitty next`	Drive the agent loop: returns the next action (implement, review, decide) per WP based on mission state
7	`/spec-kitty.review`	Display WP prompt for review, auto-move to `in_progress` ("Doing"), show next steps
8	`/spec-kitty.accept`	Run final acceptance checks, record metadata, and verify feature complete
9	`/spec-kitty.merge`	Merge feature into main branch and clean up worktree

Quality Gates & Development Tools

Optional commands for enhanced quality and development:

Command	When to Use
`/spec-kitty.analyze`	Optional, after `/spec-kitty.tasks`, before starting the `spec-kitty next` loop: Cross-artifact consistency & coverage analysis
`/spec-kitty.checklist`	Optional, anytime after `/spec-kitty.plan`: Generate custom quality checklists that validate requirements completeness, clarity, and consistency
`/spec-kitty.dashboard`	Anytime (runs in background): Open the real-time kanban dashboard in your browser. Automatically starts with `spec-kitty init` and updates as you work.

🌳 Worktree Strategy

📖 Quick Start: See the Getting Started guide for practical examples of worktree usage in context.

Spec Kitty uses an opinionated swim-lane worktree model for parallel feature development. Think of each computed lane as a swim lane on the board: that swim lane owns one long-lived branch and one long-lived worktree, and sequential WPs stay in that swim lane instead of creating a fresh worktree per WP.

Parallel Development Without Branch Switching

graph TD
    Main[main branch<br/>🔒 Clean production code]
    WT1[.worktrees/001-auth-lane-a<br/>🔐 Shared foundation swim lane]
    WT2[.worktrees/001-auth-lane-b<br/>💾 Parallel API swim lane]
    WT3[.worktrees/002-dashboard-lane-a<br/>📊 Dashboard swim lane]

    Main --> WT1
    Main --> WT2
    Main --> WT3

    WT1 -.->|🚀 Parallel work| WT2
    WT2 -.->|✅ No conflicts| WT3

    style Main fill:#e8f5e9
    style WT1 fill:#e1f5ff
    style WT2 fill:#fff3e0
    style WT3 fill:#f3e5f5

Why this works:

Planning stays in the main checkout, so artifacts remain visible and auditable
Sequential WPs in the same swim lane reuse the same worktree instead of spinning up a new one
Independent swim lanes still run in parallel in separate directories with separate branches
If task finalization computes one swim lane, the feature uses one worktree
Main branch stays clean without manual git checkout juggling

The Pattern

my-project/                    # Main repo (main branch)
├── .worktrees/
│   ├── 001-auth-system-lane-a/  # Feature 1 swim lane A (shared by sequential WPs)
│   ├── 001-auth-system-lane-b/  # Feature 1 swim lane B (parallel work)
│   └── 002-dashboard-lane-a/    # Single-swim-lane feature
├── .kittify/
├── kitty-specs/
└── ... (main branch files)

The Rules

Planning commands run in the primary repo root
Implementation branches live under .worktrees/
Trust the path printed by Spec Kitty instead of guessing the worktree name
Swim-lane features reuse .worktrees/<feature>-lane-<id> when multiple WPs share a swim lane
One computed swim lane means one worktree for the whole feature
Automatic cleanup removes swim-lane worktrees after merge

The Complete Workflow

# ========== IN MAIN REPO ==========
/spec-kitty.charter     # Step 1: Establish project governance (one time per project)

# ========== PLAN IN MAIN REPO ==========
/spec-kitty.specify          # Step 2: Create the feature artifacts
/spec-kitty.plan             # Step 3: Design technical implementation
/spec-kitty.research         # Step 4 (as needed): Research technologies, patterns, etc.
/spec-kitty.tasks            # Step 5: Break plan into actionable tasks
/spec-kitty.analyze          # Step 6 (optional): Check cross-artifact consistency

# ========== RUN AGENT LOOP (implement + review each WP) ==========
spec-kitty next --agent <agent> --mission <slug>  # Step 7: Start the agent loop
# Your agent calls: spec-kitty agent action implement WP01 --agent <name>
# Then:            spec-kitty agent action review WP01 --agent <name>
# Repeat for each WP until all are done.

# ========== IN EXECUTION WORKSPACE ==========
# spec-kitty next handles dispatch to agent action implement/review for each WP
/spec-kitty.review           # Step 9: Review and refine completed work
/spec-kitty.accept           # Step 10: Acceptance checks & final metadata
/spec-kitty.merge --push     # Step 11: Merge to the mission target branch + cleanup swim-lane worktrees

# ========== BACK IN REPOSITORY ROOT CHECKOUT ==========
# Ready for next feature!

🧭 Mission System

Spec Kitty supports missions: curated bundles of templates, commands, and guardrails for different domains. Two missions ship out of the box:

Software Dev Kitty – the original Spec-Driven Development workflow for shipping application features (default).
Deep Research Kitty – a methodology-focused workflow for evidence gathering, analysis, and synthesis.

Each mission lives under .kittify/missions/<mission-key>/ and provides:

Mission-specific templates (spec-template.md, plan-template.md, tasks-template.md, etc.)
Command guidance tuned to the domain (specify, plan, tasks, implement, review, accept)
Optional charters to bias the agent toward best practices

Selecting a Mission

Mission types are selected per mission run during /spec-kitty.specify, not during init:

# Inspect available mission types
spec-kitty mission list

# Inspect one mission type in detail
spec-kitty mission info software-dev

# Seed a new mission from a tracker ticket before /spec-kitty.specify
spec-kitty mission create --from-ticket linear:PRI-42

Mission Configuration

After you create a mission with /spec-kitty.specify, the selected mission type is recorded in that mission's metadata:

# View the mission type for one mission
spec-kitty mission current --mission 001-my-feature

# Mission metadata
cat kitty-specs/001-my-feature/meta.json

Note: init only installs project scaffolding. Mission type selection happens later, per mission, during /spec-kitty.specify.

Environment Variables

Variable	Description
`SPEC_KITTY_TEMPLATE_ROOT`	Optional. Point to a local checkout whose `templates/`, `scripts/`, and `memory/` directories should seed new projects (handy while developing Spec Kitty itself).
`SPECIFY_TEMPLATE_REPO`	Optional. Override the GitHub repository slug (`owner/name`) to fetch templates from when you explicitly want a remote source.
`SPEC_KITTY_NON_INTERACTIVE`	Force non-interactive init behavior. Equivalent to passing `--non-interactive` / `--yes`.
`SPEC_KITTY_ENABLE_SAAS_SYNC`	Opt in to hosted auth, tracker, and sync flows. Leave unset for local-only workflows.
`SPEC_KITTY_SAAS_URL`	Override the SaaS base URL used by `spec-kitty auth`, tracker discovery, and hosted sync flows.

🔧 Prerequisites

Linux/macOS (or WSL2 on Windows)
A supported AI coding agent from the Supported AI Tools section above
uv for package management
Python 3.11+
Git

If you encounter issues with an agent, please open an issue so we can refine the integration.

🚀 Releasing Stable Versions on GitHub and PyPI (Maintainers)

The stable 3.x line now lives on main and publishes from semantic tags in the form vX.Y.Z. Prerelease testing builds can also publish from main using tags such as vX.Y.ZaN. The release workflow publishes both GitHub release artifacts and the PyPI package.

0. One-Time Setup

Configure PyPI Trusted Publishing for spec-kitty-cli against .github/workflows/release.yml.
Keep 1.x-maintenance maintenance-only; do not use it for new PyPI releases.

1. Prepare Release Branch

git checkout main
git pull origin main
git checkout -b release/vX.Y.Z

# Update pyproject.toml to a release version (example: X.Y.Z or X.Y.ZaN)
# Add CHANGELOG.md entry under: ## [X.Y.Z] - YYYY-MM-DD (or prerelease ## [X.Y.ZaN] - YYYY-MM-DD)

2. Validate Locally

python scripts/release/validate_release.py --mode branch --tag-pattern "v*.*.*"
python -m pytest
python -m build
twine check dist/*
rm -rf dist/ build/

3. Open and Merge PR to `main`

git add pyproject.toml CHANGELOG.md
git commit -m "chore(release): prepare X.Y.Z"
git push origin release/vX.Y.Z

After review, merge into main with a linear-history strategy (rebase).

4. Tag and Push

git checkout main
git pull origin main
git tag vX.Y.Z -m "Release vX.Y.Z"
git push origin vX.Y.Z

For prereleases, use the exact prerelease tag instead:

git tag vX.Y.ZaN -m "Release vX.Y.ZaN"
git push origin vX.Y.ZaN

This triggers .github/workflows/release.yml.

5. Verify GitHub Release and PyPI Publication

gh release view vX.Y.Z
python -m pip index versions spec-kitty-cli

Guardrails

release-readiness.yml: runs on PRs to main (and 2.x if the maintenance branch is still active) to validate version/changelog/tests.
release.yml: runs on stable and prerelease v*.*.* tags and performs:
- test execution
- release metadata validation
- artifact build and checksums
- PyPI publication via Trusted Publishing
- GitHub Release creation with changelog notes, marked as prerelease when the tag is a prerelease

Troubleshooting

Validation fails: "Version does not advance beyond latest tag"

Check latest tag: git tag --list 'v*.*.*' --sort=-version:refname | head -1
Bump pyproject.toml to a higher semantic version

Validation fails: "CHANGELOG.md lacks a populated section"

Add ## [X.Y.Z] with release notes in CHANGELOG.md

Tag already exists:

git tag -d vX.Y.Z
git push origin :refs/tags/vX.Y.Z
git tag vX.Y.Z -m "Release vX.Y.Z"
git push origin vX.Y.Z

Installing a prerelease from PyPI:

python -m pip install --upgrade --pre spec-kitty-cli
python -m pip install --upgrade "spec-kitty-cli==X.Y.ZaN"

🛠️ Development Setup

If you're contributing to Spec Kitty or working with the source code directly, you'll need to install it in development mode:

From Local Checkout

# Clone the repository
git clone https://github.com/Priivacy-ai/spec-kitty.git
cd spec-kitty

# Install in editable mode with development dependencies
pip install -e ".[test]"

# When running spec-kitty init, set the template root to your local checkout:
export SPEC_KITTY_TEMPLATE_ROOT=$(pwd)
spec-kitty init <PROJECT_NAME> --ai=claude

# Or use the --template-root flag directly (no env var needed):
spec-kitty init <PROJECT_NAME> --ai=claude --template-root=/path/to/spec-kitty

Template Discovery Priority

The CLI searches for templates in this order:

Packaged resources: Built-in templates from the installed spec-kitty-cli
Environment override: SPEC_KITTY_TEMPLATE_ROOT for local development or source checkouts
Remote repository: SPECIFY_TEMPLATE_REPO when you explicitly want a remote template source

For development installs from source, set SPEC_KITTY_TEMPLATE_ROOT to your checkout before running spec-kitty init.

🔍 Troubleshooting

Template Discovery Issues

Error: "Templates could not be found in any of the expected locations"

This error occurs when spec-kitty init cannot locate the template files. Here's how to diagnose and fix it:

For PyPI installations:

# Reinstall the package
pip install --upgrade spec-kitty-cli

# Verify templates are bundled
python -c "from importlib.resources import files; print(files('specify_cli').joinpath('templates'))"

For development installations:

# Make sure you installed in editable mode from the repo root
cd /path/to/spec-kitty
pip install -e .

# Option 1: Use environment variable
export SPEC_KITTY_TEMPLATE_ROOT=$(pwd)
spec-kitty init my-project --ai=claude

# Option 2: Use --template-root flag (no env var needed)
spec-kitty init my-project --ai=claude --template-root=$(pwd)

# Option 3: Verify the path exists
ls -la ./templates/commands

For moved repositories: If you cloned the spec-kitty repo and moved the directory, update the environment variable:

export SPEC_KITTY_TEMPLATE_ROOT=/new/path/to/spec-kitty
spec-kitty init my-project --ai=claude

Debugging with verbose output:

# Use --debug flag to see which paths were checked
spec-kitty init my-project --ai=claude --debug --template-root=/path/to/spec-kitty

Git Credential Manager on Linux

If you're having issues with Git authentication on Linux, you can install Git Credential Manager:

#!/usr/bin/env bash
set -e
echo "Downloading Git Credential Manager v2.6.1..."
wget https://github.com/git-ecosystem/git-credential-manager/releases/download/v2.6.1/gcm-linux_amd64.2.6.1.deb
echo "Installing Git Credential Manager..."
sudo dpkg -i gcm-linux_amd64.2.6.1.deb
echo "Configuring Git to use GCM..."
git config --global credential.helper manager
echo "Cleaning up..."
rm gcm-linux_amd64.2.6.1.deb
