Why Ultra

GSD is a solid foundation — context rot solved, fresh context per plan, atomic commits, structured plans. It works. Engineers at real companies use it every day.

But after running it on complex, multi-domain builds, I kept hitting the same four walls:

Blind spots — A single researcher misses what a team of four would catch. One perspective isn't enough for complex phases.
Weak plans — Plans look good until you're three tasks in and realize the architecture doesn't hold. No one challenged the assumptions.
Bugs slip through — A single verifier does its best, but it can't simultaneously be the defender, the attacker, and the impartial judge.
No learning — Phase 8 is as expensive as Phase 1. The system doesn't get smarter from what it's already built.

Ultra is my fix for all four:

Problem	GSD	Ultra
Blind spots	1 researcher	4-perspective research swarm
Weak plans	Single planner	Builder/Critic adversarial debate
Bugs slip	Single verifier	Defender + Attacker + Auditor triple-check
No learning	Fresh start every phase	Knowledge flywheel — conventions compound

Ultra is GSD's natural evolution, not a bolt-on. Every Ultra command enriches what's already there. You can use GSD commands, Ultra commands, or mix them freely.

Getting Started

npx get-shit-done-cc@latest

The installer prompts you to choose:

Runtime — Claude Code, OpenCode, Gemini, or all
Location — Global (all projects) or local (current project only)

Verify with /gsd:help inside your chosen runtime.

Staying Updated

GSD evolves fast. Update periodically:

npx get-shit-done-cc@latest

Non-interactive Install (Docker, CI, Scripts)

# Claude Code
npx get-shit-done-cc --claude --global   # Install to ~/.claude/
npx get-shit-done-cc --claude --local    # Install to ./.claude/

# OpenCode (open source, free models)
npx get-shit-done-cc --opencode --global # Install to ~/.config/opencode/

# Gemini CLI
npx get-shit-done-cc --gemini --global   # Install to ~/.gemini/

# All runtimes
npx get-shit-done-cc --all --global      # Install to all directories

Use --global (-g) or --local (-l) to skip the location prompt. Use --claude, --opencode, --gemini, or --all to skip the runtime prompt.

Development Installation

Clone the repository and run the installer locally:

git clone https://github.com/bslevin87/get-shit-done_ultra.git
cd get-shit-done_ultra
node bin/install.js --claude --local

Installs to ./.claude/ for testing modifications before contributing.

Agent Teams Mode (Experimental)

Ultra can use Claude Code's native Agent Teams for inter-agent coordination — live messaging instead of file relay, shared task lists instead of manual orchestration. This is experimental (Opus 4.6+, Feb 2026).

Enable:

export CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1

Or add to ~/.claude/settings.json:

{
  "env": {
    "CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS": "1"
  }
}

When enabled, all Ultra workflows use native teammate coordination. When disabled (default), existing Task() subagent behavior is unchanged. Both modes produce identical output files.

Feature	Task() Subagents	Agent Teams
Communication	File relay	Native mailbox
Debate (verify)	Moderator reads 3 files	Live messaging
RELAY (research)	Written sections in files	Direct messages
Task management	Orchestrator manages	Shared task list
Display	Sequential	Split-pane

Ultra Setup (Optional)

Ultra works out of the box. For multi-domain phases, add a gsd-ultra.json to your project root:

{
  "domains": {
    "auth": { "paths": ["src/features/auth/"], "owner": "teammate-1" },
    "tasks": { "paths": ["src/features/tasks/"], "owner": "teammate-2" }
  },
  "shared_paths": ["src/types/", "src/lib/"],
  "pipeline": {
    "adversarial_plan": { "max_rounds": 5 },
    "adversarial_verify": { "max_debate_rounds": 3 }
  }
}

Not required. Without it, Ultra uses smart defaults and auto-discovers domains from your codebase.

Recommended: Skip Permissions Mode

GSD is designed for frictionless automation. Run Claude Code with:

claude --dangerously-skip-permissions

Tip

This is how GSD is intended to be used — stopping to approve date and git commit 50 times defeats the purpose.

Alternative: Granular Permissions

If you prefer not to use that flag, add this to your project's .claude/settings.json:

{
  "permissions": {
    "allow": [
      "Bash(date:*)",
      "Bash(echo:*)",
      "Bash(cat:*)",
      "Bash(ls:*)",
      "Bash(mkdir:*)",
      "Bash(wc:*)",
      "Bash(head:*)",
      "Bash(tail:*)",
      "Bash(sort:*)",
      "Bash(grep:*)",
      "Bash(tr:*)",
      "Bash(git add:*)",
      "Bash(git commit:*)",
      "Bash(git status:*)",
      "Bash(git log:*)",
      "Bash(git diff:*)",
      "Bash(git tag:*)"
    ]
  }
}

How It Works

The complete GSD Ultra flow — from idea to shipped code with compound learning:

                          ┌── GSD FOUNDATION ──┐    ┌─────────── ULTRA PIPELINE ───────────┐
                          │                     │    │                                       │
/gsd:new-project ──▶ /gsd:discuss-phase ──▶ RESEARCH ──▶ PLAN ──▶ EXECUTE ──▶ VERIFY ──▶ FIX ──▶ LEARN
    or                  (your vision)       Swarm ×4   Builder   Parallel   Defender    Cluster  Flywheel
/gsd:map-codebase                                      vs        domains    vs          + Ralph
                                                       Critic               Attacker
                                                                            vs Auditor

Step 0: Initialize Your Project

New project? → /gsd:new-project — In-depth interview about your idea. Creates PROJECT.md, REQUIREMENTS.md, ROADMAP.md, STATE.md.

Existing code? → /gsd:map-codebase first — Spawns parallel agents to analyze your stack, architecture, conventions, and concerns. Then /gsd:new-project knows your codebase.

Step 1: Discuss Phase — Shape Your Vision

/gsd:discuss-phase 1

This is where you shape the implementation. Your roadmap has a sentence or two per phase. That's not enough context to build something the way you imagine it.

The system analyzes the phase and identifies gray areas based on what's being built:

Visual features → Layout, density, interactions, empty states
APIs/CLIs → Response format, flags, error handling, verbosity
Content systems → Structure, tone, depth, flow
Organization tasks → Grouping criteria, naming, duplicates, exceptions

For each area, it asks until you're satisfied. The output — CONTEXT.md — feeds directly into every downstream stage. The deeper you go here, the more the system builds what you actually want. Skip it and you get reasonable defaults. Use it and you get your vision.

Step 2: Research Swarm — 4 Perspectives

/ultra:research-swarm 1

Four researchers investigate simultaneously, each bringing a different lens:

Researcher	Answers
Pattern Analyst	How have others solved this? Libraries, patterns, anti-patterns
Domain Expert	What does this domain require? Best practices, compliance
Risk Analyst	What could go wrong? Security, performance, dependencies
UX Investigator	How should users experience this? Accessibility, interactions

Cross-perspective RELAY protocol — when a researcher discovers info affecting another's domain, they flag it. Synthesizer resolves conflicts (safety > convenience, evidence > opinion).

Step 3: Adversarial Plan — Builder vs Critic

/ultra:adversarial-plan 1

Builder creates the plan. Critic attacks it with BLOCKER / WARNING / SUGGESTION findings. Builder revises. Critic re-reviews. Loop until zero BLOCKERs or max 5 rounds.

Plans include interface contracts between domains, file ownership declarations, and domain-to-wave assignment. Result: plans that survive scrutiny before a single line of code is written.

Step 4: Parallel Execute — Domain Ownership

/ultra:parallel-execute 1

Domains execute in parallel with strict file ownership:

Level	Permission
OWN	Full read/write
SHARED	Append only — add new, don't modify existing
READ-ONLY	Import and reference only
DO NOT TOUCH	No access

Deferred integration — teammates build domains independently, lead wires them together after all complete. No merge conflicts, no race conditions.

Step 5: Adversarial Verify — Triple-Check Debate

/ultra:adversarial-verify 1

Three independent assessors, then structured debate:

Round 1: Defender, Attacker, and Auditor assess independently (parallel)
Round 2: Attacker presents ATK-N findings → Defender responds (Concede/Dispute/Mitigate) → Auditor rules (SUSTAINED/OVERRULED/SPLIT)
Round 3: Consensus resolution for any SPLIT rulings

When all three flag the same issue = consensus failure (strongest signal). Verdict: PASS (90%+) / CONDITIONAL_PASS (70%+) / FAIL.

Step 6: Gap Close — Cluster + Fix + Self-Verify

/ultra:gap-close 1

Clusters related bugs by file and domain — fixes root causes, not symptoms. Selects the right agent (executor for missing features, debugger for logic bugs). Each fixer runs Ralph 3-level self-verify: code review → logical walk-through → runtime verification. Up to 5 retries with escalation analysis.

Step 7: Retrospective — The Flywheel

/ultra:retrospective 1

The compound learning mechanism. Extracts conventions from completed code, proposes CLAUDE.md additions (you approve each one), logs architectural decisions as DEC-{NNN} to STATE.md. Every phase makes the next one faster.

Then Repeat

/gsd:discuss-phase 2
/ultra:research-swarm 2
/ultra:adversarial-plan 2
/ultra:parallel-execute 2
/ultra:adversarial-verify 2
/ultra:gap-close 2
/ultra:retrospective 2
...
/gsd:complete-milestone

Or chain everything for a phase:

/ultra:full-pipeline 2

Quick Mode

/gsd:quick

For ad-hoc tasks that don't need the full pipeline. Same agents, same quality — skips research, debate, and verification. Use for bug fixes, small features, config changes.

The Knowledge Flywheel

Ultra's secret weapon. Each completed phase feeds lessons back into the system:

Phase 1 → RETROSPECTIVE → 3 conventions added to CLAUDE.md
Phase 2 → Research swarm reads those conventions → finds patterns 20% faster
Phase 3 → Planner reads 5 conventions + 4 decisions → better first-draft plans
Phase 5 → Verifier checks against conventions → finds issues faster
Phase 8 → Research 60% faster, verification 75% fewer findings

How it works:

/ultra:retrospective analyzes completed work
Extracts patterns from the code you just built
Proposes CLAUDE.md convention additions — you approve each one
Logs architectural decisions to STATE.md as DEC-{NNN} entries
Reviews domain boundaries for shifts

The math: Each convention eliminates a class of errors. Five conventions compounding across three phases = exponential improvement. By Phase 8, the system knows your codebase so well that plans converge in 1-2 rounds instead of 5.

Skipping retrospectives costs ~40% of Ultra's long-term value. Don't skip them.

When to Use What

Criterion	Raw Claude Code	GSD	GSD Ultra
Files touched	1-2	3-10	5-30+
Domains	1	1-2	2-6
Quality needs	Prototype	Production	Production+
Research	Ad hoc	Single researcher	4-perspective swarm
Planning	Inline	Single planner	Builder/Critic debate
Execution	Single thread	Wave-parallel	Domain-parallel + deferred integration
Verification	Manual	Single verifier	Triple-check debate
Learning	None	STATE.md	Full flywheel
Cost	$0.50-2	$2-8	$5-20
Time	5-15 min	15-45 min	30-90 min

Quick rules:

Bug fix or small feature? → /gsd:quick
Standard phase, 1-2 domains? → GSD workflow
Complex phase, 3+ domains, quality critical? → Ultra pipeline
Want maximum quality with zero manual orchestration? → /ultra:full-pipeline

Configuration

GSD stores project settings in .planning/config.json. Configure during /gsd:new-project or update later with /gsd:settings.

Core Settings

Setting	Options	Default	What it controls
`mode`	`yolo`, `interactive`	`interactive`	Auto-approve vs confirm at each step
`depth`	`quick`, `standard`, `comprehensive`	`standard`	Planning thoroughness (phases × plans)

Model Profiles

Control which Claude model each agent uses. Balance quality vs token spend.

Profile	Planning	Execution	Verification	Research	Est. Cost/Phase
`quality`	Opus	Opus	Sonnet	Opus	~$27
`balanced` (default)	Opus	Sonnet	Sonnet	Sonnet	~$13
`budget`	Sonnet	Sonnet	Haiku	Haiku	~$8
`eco`	Sonnet	Sonnet	Haiku	Haiku	~$4

Switch profiles:

/gsd:set-profile eco

Eco is for well-established projects with strong CLAUDE.md conventions. The knowledge flywheel makes planning and verification easier, so cheaper models still deliver good results. Don't use eco for Phase 1 of a new project.

Workflow Agents

These spawn additional agents during planning/execution. They improve quality but add tokens and time.

Setting	Default	What it does
`workflow.research`	`true`	Researches domain before planning each phase
`workflow.plan_check`	`true`	Verifies plans achieve phase goals before execution
`workflow.verifier`	`true`	Confirms must-haves were delivered after execution

Use /gsd:settings to toggle these, or override per-invocation:

/gsd:plan-phase --skip-research
/gsd:plan-phase --skip-verify

Execution

Setting	Default	What it controls
`parallelization.enabled`	`true`	Run independent plans simultaneously
`planning.commit_docs`	`true`	Track `.planning/` in git

Git Branching

Setting	Options	Default	What it does
`git.branching_strategy`	`none`, `phase`, `milestone`	`none`	Branch creation strategy
`git.phase_branch_template`	string	`gsd/phase-{phase}-{slug}`	Template for phase branches
`git.milestone_branch_template`	string	`gsd/{milestone}-{slug}`	Template for milestone branches

Why It Works

Context Engineering

Claude Code is incredibly powerful if you give it the context it needs. Most people don't.

GSD handles it for you:

File	What it does
`PROJECT.md`	Project vision, always loaded
`research/`	Ecosystem knowledge (stack, features, architecture, pitfalls)
`REQUIREMENTS.md`	Scoped v1/v2 requirements with phase traceability
`ROADMAP.md`	Where you're going, what's done
`STATE.md`	Decisions, blockers, position — memory across sessions
`PLAN.md`	Atomic task with XML structure, verification steps
`SUMMARY.md`	What happened, what changed, committed to history
`RETROSPECTIVE.md`	Patterns, decisions, conventions — flywheel fuel

Adversarial Verification

Single-perspective verification misses things. Ultra's triple-check debate catches what individuals can't:

Defender builds an evidence matrix — requirement → file:line proof
Attacker hunts bugs with composite expertise (security + edge cases + code quality)
Auditor rules on disputes with a weighted compliance score

When all three flag the same issue, it's a consensus failure — the strongest signal that something needs fixing.

Knowledge Compounding

Most AI systems have no memory. They repeat the same mistakes, explore the same dead ends, rediscover the same patterns. Ultra's flywheel breaks this cycle:

10% improvement per stage:  1.1 × 1.1 × 1.1 × 1.1 = 1.46× overall
20% improvement per stage:  1.2 × 1.2 × 1.2 × 1.2 = 2.07× overall

The multiplicative effect is why skipping stages destroys more value than it saves — you're not losing one stage's benefit, you're losing its compounding effect on everything downstream.

XML Prompt Formatting

Every plan is structured XML optimized for Claude:

<task type="auto">
  <name>Create login endpoint</name>
  <files>src/app/api/auth/login/route.ts</files>
  <action>
    Use jose for JWT (not jsonwebtoken - CommonJS issues).
    Validate credentials against users table.
    Return httpOnly cookie on success.
  </action>
  <verify>curl -X POST localhost:3000/api/auth/login returns 200 + Set-Cookie</verify>
  <done>Valid credentials return cookie, invalid return 401</done>
</task>

Precise instructions. No guessing. Verification built in.

Multi-Agent Orchestration

Every stage uses the same pattern: a thin orchestrator spawns specialized agents, collects results, and routes to the next step.

The orchestrator never does heavy lifting. It spawns agents, waits, integrates results. The result: entire phases run — deep research, adversarial planning, thousands of lines of code across parallel domains, triple-check verification — and your main context window stays at 30-40%.

Atomic Git Commits

Each task gets its own commit immediately after completion:

abc123f docs(08-02): complete user registration plan
def456g feat(08-02): add email confirmation flow
hij789k feat(08-02): implement password hashing

Note

Benefits: Git bisect finds exact failing task. Each task independently revertable. Clear history for Claude in future sessions.

Security

Protecting Sensitive Files

GSD's codebase mapping and analysis commands read files to understand your project. Protect files containing secrets by adding them to Claude Code's deny list:

Open Claude Code settings (.claude/settings.json or global)
Add sensitive file patterns to the deny list:

{
  "permissions": {
    "deny": [
      "Read(.env)",
      "Read(.env.*)",
      "Read(**/secrets/*)",
      "Read(**/*credential*)",
      "Read(**/*.pem)",
      "Read(**/*.key)"
    ]
  }
}

This prevents Claude from reading these files entirely, regardless of what commands you run.

Important

GSD includes built-in protections against committing secrets, but defense-in-depth is best practice. Deny read access to sensitive files as a first line of defense.

Troubleshooting

Commands not found after install?

Restart Claude Code to reload slash commands
Verify files exist in ~/.claude/commands/gsd/ (global) or ./.claude/commands/gsd/ (local)

Commands not working as expected?

Run /gsd:help to verify installation
Re-run npx get-shit-done-cc to reinstall

Updating to the latest version?

npx get-shit-done-cc@latest

Using Docker or containerized environments?

If file reads fail with tilde paths (~/.claude/...), set CLAUDE_CONFIG_DIR before installing:

CLAUDE_CONFIG_DIR=/home/youruser/.claude npx get-shit-done-cc --global

Uninstalling

# Global installs
npx get-shit-done-cc --claude --global --uninstall
npx get-shit-done-cc --opencode --global --uninstall

# Local installs (current project)
npx get-shit-done-cc --claude --local --uninstall
npx get-shit-done-cc --opencode --local --uninstall

Community Ports

OpenCode and Gemini CLI are now natively supported via npx get-shit-done-cc.
