Superhuman: AI-Native Development Lifecycle

Superhuman is a development lifecycle built from the ground up for AI agents. Traditional methods like Agile, Waterfall, and TDD were designed around human constraints - limited parallelism, context switching costs, communication overhead, and meetings. AI agents have none of these constraints. Superhuman exploits this by decomposing work into dependency-graphed sub-tasks, executing independent tasks in parallel waves, enforcing TDD verification at every step, and tracking everything on a persistent board that survives across sessions.

The model has 7 phases: INTAKE - DECOMPOSE - DISCOVER - PLAN - EXECUTE - VERIFY - CONVERGE.

Activation Banner

At the very start of every Superhuman invocation, before any other output, display this ASCII art banner:

███████╗██╗   ██╗██████╗ ███████╗██████╗ ██╗  ██╗██╗   ██╗███╗   ███╗ █████╗ ███╗   ██╗

This banner is mandatory. It signals to the user that Superhuman mode is active.

Activation Protocol

Immediately after displaying the banner, enter plan mode before doing anything else:

1. On platforms with native plan mode (e.g., Claude Code's EnterPlanMode, Gemini CLI's planning mode): invoke the native plan mode mechanism immediately.
2. On platforms without native plan mode: simulate plan mode by completing all planning phases (INTAKE through PLAN) in full before making any code changes. Present the complete plan to the user for explicit approval before proceeding to EXECUTE.

This ensures that every Superhuman invocation begins with structured thinking. The first four phases (INTAKE, DECOMPOSE, DISCOVER, PLAN) are inherently planning work - no files should be created or modified until the user has approved the plan and execution begins in Phase 5.

Session Resume Protocol

When Superhuman is invoked and a .superhuman/board.md already exists in the project root:

1. Detect: Read the existing board and determine its status (in-progress, blocked, completed)
2. Display: Print a compact status summary showing completed/in-progress/blocked/remaining tasks
3. Resume: Pick up from the last incomplete wave - do NOT restart from INTAKE
4. Reconcile: If the codebase has changed since the last session (e.g., manual edits, other commits), run a quick diff check against the board's expected state and flag any conflicts before resuming

If the board is marked completed, ask the user whether to start a new Superhuman session (archive the old board to .superhuman/archive/) or review the completed work.

Never blow away an existing board without explicit user confirmation.

Codebase Convention Detection

Before INTAKE begins, automatically detect the project's conventions by scanning for key files. This grounds all subsequent phases in reality rather than assumptions.

Auto-detect Checklist

Output

Write the detected conventions to the board under a ## Project Conventions section. Reference these conventions in every subsequent phase - particularly PLAN and the Mandatory Tail Tasks verification step.

When to Use This Skill

Use Superhuman when:

• Multi-step feature development touching 3+ files or components
• User says "build this end-to-end" or "plan and execute this"
• User says "break this into tasks" or "sprint plan this"
• Any task requiring planning + implementation + verification
• Greenfield projects, major refactors, or migrations
• Complex bug fixes that span multiple systems

Do NOT use Superhuman when:

• Single-file bug fixes or typo corrections
• Quick questions or code explanations
• Tasks the user wants to do manually with your guidance
• Pure research or exploration tasks

Key Principles

1. Dependency-First Decomposition

Every task is a node in a directed acyclic graph (DAG), not a flat list. Dependencies between tasks are explicit. This prevents merge conflicts, ordering bugs, and wasted work.

2. Wave-Based Parallelism

Tasks at the same depth in the dependency graph form a "wave". All tasks in a wave execute simultaneously via parallel agents. Waves execute in serial order. This maximizes throughput while respecting dependencies.

3. Test-First Verification

Every sub-task writes tests before implementation. A task is only "done" when its tests pass. No exceptions for "simple" changes - tests are the proof of correctness.

4. Persistent State

All progress is tracked in .superhuman/board.md in the project root. This file survives across sessions, enabling resume, audit, and handoff. The user chooses during INTAKE whether the board is git-tracked or gitignored.

5. Interactive Intake

Never assume. Scale questioning depth to task complexity - simple tasks get 3 questions, complex ones get 8-10. Extract requirements, constraints, and success criteria before writing a single line of code.

Core Concepts

The 7 Phases

INTAKE --> DECOMPOSE --> DISCOVER --> PLAN --> EXECUTE --> VERIFY --> CONVERGE
  |           |             |          |         |           |          |
  |  gather   |  build DAG  | research | detail  | parallel  | test +   | merge +
  |  context  |  + waves    | per task | per task| waves     | verify   | close

Task Graph

A directed acyclic graph (DAG) where each node is a sub-task and edges represent dependencies. Tasks with no unresolved dependencies can execute in parallel. See references/dependency-graph-patterns.md.

Execution Waves

Groups of independent tasks assigned to the same depth level in the DAG. Wave 1 runs first (all tasks in parallel), then Wave 2 (all tasks in parallel), and so on. See references/wave-execution.md.

Board

The .superhuman/board.md file is the single source of truth. It contains the intake summary, task graph, wave assignments, per-task status, research notes, plans, and verification results. See references/board-format.md.

Sub-task Lifecycle

pending --> researching --> planned --> in-progress --> verifying --> done
                                           |                |
                                           +--- blocked     +--- failed (retry)

Phase 1: INTAKE (Interactive Interview)

The intake phase gathers all context needed to decompose the task. Scale depth based on complexity.

Complexity Detection

• Simple (single component, clear scope): 3 questions
• Medium (multi-component, some ambiguity): 5 questions
• Complex (cross-cutting, greenfield, migration): 8-10 questions

Core Questions (always ask)

1. Problem Statement: What exactly needs to be built or changed? What triggered this work?
2. Success Criteria: How will we know this is done? What does "working" look like?
3. Constraints: Are there existing patterns, libraries, or conventions we must follow?

Extended Questions (medium + complex)

4. Existing Code: Is there related code already in the repo? Should we extend it or build fresh?
5. Dependencies: Does this depend on external APIs, services, or other in-progress work?

Deep Questions (complex only)

6. Edge Cases: What are the known edge cases or failure modes?
7. Testing Strategy: Are there existing test patterns? Integration vs unit preference?
8. Rollout: Any migration steps, feature flags, or backwards compatibility needs?
9. Documentation: What docs need updating? API docs, README, architecture docs?
10. Priority: Which parts are most critical? What can be deferred if needed?

Board Persistence Question (always ask)

Ask: "Should the .superhuman/ board be git-tracked (audit trail, resume across machines) or gitignored (local working state)?"

Output

Write the intake summary to .superhuman/board.md with all answers captured. See references/intake-playbook.md for the full question bank organized by task type.

Phase 2: DECOMPOSE (Task Graph Creation)

Break the intake into atomic sub-tasks and build the dependency graph.

Sub-task Anatomy

Each sub-task must have:

• ID: Sequential identifier (e.g., SH-001)
• Title: Clear, action-oriented (e.g., "Create user authentication middleware")
• Description: 2-3 sentences on what this task does
• Type: code | test | docs | infra | config
• Complexity: S (< 50 lines) | M (50-200 lines) | L (200+ lines - consider splitting)
• Dependencies: List of task IDs this depends on (e.g., [SH-001, SH-003])

Decomposition Rules

1. Every task should be S or M complexity. If L, decompose further
2. Test tasks are separate from implementation tasks
3. Infrastructure/config tasks come before code that depends on them
4. Documentation tasks depend on the code they document
5. Aim for 5-15 sub-tasks. Fewer means under-decomposed; more means over-engineered
6. Every task graph MUST end with three mandatory tail tasks (see below)
7. Apply the complexity budget (see below)

Complexity Budget

After decomposition, sanity-check total scope before proceeding:

• Count the total number of tasks by complexity: S (small), M (medium), L (large)
• If any L tasks remain, decompose them further - L tasks are not allowed
• If total estimated scope exceeds 15 M-equivalent tasks (where 1 L = 3 M, 1 S = 0.5 M), flag to the user that scope may be too large for a single Superhuman session
• Suggest splitting into multiple Superhuman sessions with clear boundaries (e.g., "Session 1: backend API, Session 2: frontend integration")
• The user can override and proceed, but they must explicitly acknowledge the scope

Mandatory Tail Tasks

Every Superhuman task graph must include these three tasks as the final tasks, in this order:

Third-to-last task: Self Code Review

• Type: review
• Title: "Self code review of all changes"
• Description: Run a structured code review of all changes made across every completed sub-task using the code-review-mastery methodology. Get the full diff of all changes since the rollback point. Execute the review pyramid bottom-up: Security > Correctness > Performance > Design > Readability > Convention > Testing. Classify each finding as [MAJOR] or [MINOR]. Fix all [MAJOR] findings immediately and address reasonable [MINOR] findings. Re-run the review after fixes to confirm no new issues were introduced. Only proceed when no [MAJOR] findings remain.
• Dependencies: All other implementation/test/docs tasks
• Acceptance Criteria: Zero [MAJOR] findings remaining after fixes. All [MINOR] findings documented on the board (fixed or explicitly deferred).

Second-to-last task: Requirements Validation

• Type: verify
• Title: "Validate changes against original requirements"
• Description: Review all changes made across every completed sub-task and compare them against the original user prompt and intake summary. Verify that every requirement, success criterion, and constraint from INTAKE is satisfied. If any requirement is unmet or the implementation deviates from what was asked, flag the gaps and loop back to EXECUTE to address them. Do NOT proceed to the final task until all requirements are confirmed met.
• Dependencies: The self code review task above
• Acceptance Criteria: Every success criterion from INTAKE is demonstrably satisfied. If gaps are found, reiterate until they are resolved.

Last task: Full Project Verification

• Type: verify
• Title: "Run full project verification suite"
• Description: Run all available verification checks in the repo, in order. Use the project's package manager scripts (check package.json, Makefile, pyproject.toml, etc.) - never invoke tools directly. Skip any that are not configured in the project - only run what exists:
  1. Tests - Run the test script (npm test, yarn test, pnpm test, make test, pytest, etc.)
  2. Lint - Run the lint script (npm run lint, yarn lint, pnpm lint, make lint, etc.)
  3. Typecheck - Run the typecheck script (npm run typecheck, yarn typecheck, pnpm typecheck, make typecheck, etc.)
  4. Build - Run the build script (npm run build, yarn build, pnpm build, make build, etc.)
• Dependencies: The requirements validation task above
• Acceptance Criteria: All available checks pass. If any check fails, fix the issues and re-run until green. Do not mark the board as complete until every available check passes.

Build the DAG

1. List all sub-tasks
2. For each task, identify which other tasks must complete first
3. Draw edges from dependencies to dependents
4. Verify no cycles exist (it's a DAG, not a general graph)

Assign Waves

Group tasks by depth level in the DAG:

• Wave 1: Tasks with zero dependencies (roots of the DAG)
• Wave 2: Tasks whose dependencies are all in Wave 1
• Wave N: Tasks whose dependencies are all in Waves 1 through N-1

Present for Approval

Generate an ASCII dependency graph and wave assignment table. Present to the user and wait for explicit approval before proceeding.

Example output:

Task Graph:
  SH-001 [config: Init project structure]
    |
    +---> SH-002 [code: Database schema]
    |       |
    |       +---> SH-004 [code: User model]
    |       +---> SH-005 [code: Auth model]
    |
    +---> SH-003 [code: API router setup]
              |
              +---> SH-006 [code: Auth endpoints]
                      |
                      +---> SH-007 [test: Auth integration tests]
                      +---> SH-008 [docs: API documentation]

  --- Mandatory Tail Tasks ---
  SH-007, SH-008
    |
    +---> SH-009 [review: Self code review of all changes]
              |
              +---> SH-010 [verify: Validate changes against original requirements]
                        |
                        +---> SH-011 [verify: Run full project verification suite]

Wave Assignments:
  Wave 1: SH-001                          (1 task, serial)
  Wave 2: SH-002, SH-003                  (2 tasks, parallel)
  Wave 3: SH-004, SH-005, SH-006         (3 tasks, parallel)
  Wave 4: SH-007, SH-008                  (2 tasks, parallel)
  Wave 5: SH-009                          (1 task, self code review)
  Wave 6: SH-010                          (1 task, requirements validation)
  Wave 7: SH-011                          (1 task, full project verification)

Update the board with the full task graph and wave assignments. See references/dependency-graph-patterns.md for common patterns and the wave assignment algorithm.

Phase 3: DISCOVER (Parallel Research)

Research each sub-task before planning implementation. This phase is parallelizable per wave.

Per Sub-task Research

For each sub-task, investigate:

1. Codebase Exploration

   • Find existing patterns, utilities, and conventions relevant to this task
   • Identify files that will be created or modified
   • Check for reusable functions, types, or components
   • Understand the testing patterns used in the project

2. Web Research (when codebase context is insufficient)

   • Official documentation for libraries and APIs involved
   • Best practices and common patterns
   • Known gotchas or breaking changes

3. Risk Assessment

   • Flag unknowns or ambiguities
   • Identify potential conflicts with other sub-tasks
   • Note any assumptions that need validation

Execution Strategy

• Launch parallel Explore agents for all tasks in Wave 1 simultaneously
• Once Wave 1 research completes, launch Wave 2 research, and so on
• Each agent writes its findings to the board under the respective task

Output

Append research notes to each sub-task on the board:

• Key files identified
• Reusable code/patterns found
• Risks and unknowns flagged
• External docs referenced

Phase 4: PLAN (Execution Planning)

Create a detailed execution plan for each sub-task based on research findings.

Per Sub-task Plan

For each sub-task, specify:

1. Files to Create/Modify: Exact file paths
2. Test Files: Test file paths (TDD - these are written first)
3. Implementation Approach: Brief description of the approach
4. Acceptance Criteria: Specific, verifiable conditions for "done"
5. Test Cases: List of test cases to write
   • Happy path tests
   • Edge case tests
   • Error handling tests

Planning Rules

1. Tests are always planned before implementation
2. Each plan must reference specific reusable code found in DISCOVER
3. Plans must respect the project's existing conventions (naming, structure, patterns)
4. If a plan reveals a missing dependency, update the task graph (re-approve with user)

Output

Update each sub-task on the board with its execution plan. The board now contains everything an agent needs to execute the task independently.

Phase 5: EXECUTE (Wave-Based Implementation)

Execute tasks wave by wave. Within each wave, spin up parallel agents for independent tasks.

Pre-Execution Snapshot

Before executing the first wave, create a git safety net:

1. Ensure all current changes are committed or stashed
2. Record the current commit hash on the board under ## Rollback Point
3. If execution goes catastrophically wrong (build broken after max retries, critical files corrupted), the user can git reset --hard to this commit
4. Remind the user of the rollback point hash when flagging unrecoverable failures

Wave Execution Loop

for each wave in [Wave 1, Wave 2, ..., Wave N]:
  for each task in wave (in parallel):
    1. Write tests (TDD - red phase)
    2. Implement code to make tests pass (green phase)
    3. Refactor if needed (refactor phase)
    4. Update board status: in-progress -> verifying
  wait for all tasks in wave to complete
  run wave boundary checks (conflict resolution, progress report)
  proceed to next wave

Agent Context Handoff Format

Each parallel agent receives a standardized prompt with these sections:

## Task: {SH-XXX} - {Title}

### Context
{Description from the board}

### Project Conventions
{Detected conventions from Codebase Convention Detection - package manager, test runner, linter, directory patterns}

### Research Notes
{Findings from DISCOVER phase for this task}

### Execution Plan
- Files to create/modify: {list}
- Test files: {list}
- Approach: {from PLAN phase}

### Acceptance Criteria
{Specific, verifiable conditions from PLAN phase}

### Rules
1. Follow TDD: write tests first, then implement
2. Use the project's existing patterns and conventions
3. Do NOT modify files outside your task scope
4. If you encounter a blocker, stop and report it - do not work around it
5. Update the board with your status when done

Wave Boundary Checks

After all tasks in a wave complete, before proceeding to the next wave:

1. Conflict Resolution

• Check if any two agents in the wave modified the same file
• If conflicts exist: review both changes, merge them intelligently (prefer the change that better satisfies its task's acceptance criteria), and verify the merged result
• If conflicts cannot be auto-resolved: flag to the user with both versions and let them decide
• Run a quick build/test check after any merge to catch integration issues early

2. Progress Report Print a compact status table after each wave:

Wave 2 Complete (3/6 waves done)
-----------------------------------------
| Task   | Status | Notes               |
|--------|--------|----------------------|
| SH-001 | done   |                      |
| SH-002 | done   |                      |
| SH-003 | done   |                      |
| SH-004 | done   | wave 2               |
| SH-005 | done   | wave 2               |
| SH-006 | next   | wave 3               |
| SH-007 | next   | wave 3               |
| SH-008 | queued | wave 4               |
-----------------------------------------

Scope Creep Guard

During EXECUTE, agents may discover additional work needed ("oh, this also needs X"). Handle scope creep strictly:

1. Blocking discovery (can't complete the current task without it): Add a new task to the DAG, assign it to the current or next wave, and flag the change to the user on the board. Continue with other tasks in the wave.
2. Non-blocking discovery (nice-to-have, related improvement, cleanup): Do NOT absorb it. Add it to a ## Deferred Work section on the board. Mention it in the CONVERGE summary. The user decides whether to start a new Superhuman session for it.
3. Never silently expand scope - every addition to the DAG must be visible on the board and flagged in the next progress report.

Handling Blocked Tasks

If a task cannot proceed:

1. Mark it as blocked on the board with a reason
2. Continue with non-blocked tasks in the same wave
3. After the wave completes, reassess blocked tasks
4. If the blocker is resolved, add the task to the next wave

Handling Failures

If an agent fails to complete a task:

1. Capture the error/failure reason on the board
2. Attempt one retry with adjusted approach
3. If retry fails, mark as failed and flag for user attention with the rollback point hash
4. Continue with other tasks - don't let one failure block the wave

See references/wave-execution.md for detailed agent orchestration patterns.

Phase 6: VERIFY (Per-Task + Integration)

Every sub-task must prove it works before closing.

Per-Task Verification

For each completed sub-task, run:

1. Tests: Run the task's test suite - all tests must pass
2. Lint: Run the project's linter on modified files
3. Type Check: Run type checker if applicable (TypeScript, mypy, etc.)
4. Build: Verify the project still builds

Integration Verification

After each wave completes:

1. Run tests for tasks that depend on this wave's output
2. Check for conflicts between parallel tasks (file conflicts, API mismatches)
3. Run the full test suite if available

Verification Loop

if all checks pass:
  mark task as "done"
  update board with verification report
else:
  mark task as "failed"
  loop back to EXECUTE for this task (max 2 retries)
  if still failing after retries:
    flag for user attention
    continue with other tasks

Output

Update each sub-task on the board with a verification report:

• Tests: pass/fail (with details on failures)
• Lint: clean/issues
• Type check: pass/fail
• Build: pass/fail

See references/verification-framework.md for the full verification protocol.

Phase 7: CONVERGE (Final Integration)

Merge all work and close out the board.

Steps

1. Merge: If using worktrees or branches, merge all work into the target branch
2. Full Test Suite: Run the complete project test suite
3. Documentation: Update any docs that were part of the task scope
4. Summary: Generate a change summary with:
   • Files created/modified (with line counts)
   • Tests added (with coverage if available)
   • Key decisions made during execution
   • Any deferred work or follow-ups
5. Close Board: Mark the board as completed with a timestamp
6. Suggest Commit: Propose a commit message summarizing the work

Board Finalization

The completed board serves as an audit trail:

• Full history of all 7 phases
• Every sub-task with its research, plan, and verification
• Timeline of execution
• Any issues encountered and how they were resolved
