Singletrack

Software Delivery Process

The Core Philosophy

Singletrack is an AI-first software delivery framework built on Intent-Driven Development.

Singletrack helps engineers and teams move from vibe coding to agentic engineering.

Instead of asking an AI to “write code,” you ask it to fulfill a clear Intent with constraints, phase gates, and measurable outcomes.

The mindset shift

Traditional sprint workflows often slow down when AI can execute quickly but teams still coordinate manually.

Singletrack solves this by separating thinking and execution into explicit roles, each with one job and one output.

It is the operating shift from vibe coding guesswork to disciplined agentic engineering.

The goal is not more prompts. The goal is better decisions before code.

The five-phase lifecycle

Singletrack separates delivery into five coordinated phases:

  1. Step 1 - Product Manager (the What)
  2. Step 2 - Scout (Context Burst)
  3. Step 3 - Architect (Spec Generation)
  4. Step 4 - Coder (Implementation)
  5. Step 5 - Verifier (QA)

Each persona handles a different risk:

  • Product Manager: ambiguity risk
  • Scout: system reality and constraint risk
  • Architect: specification ambiguity risk
  • Coder: implementation defect risk
  • Verifier: false-complete risk

Execution principles

To keep speed high without quality regressions:

  1. Define intent before implementation.
  2. Force tradeoff selection before architecture.
  3. Step 3a - Context Burst (Discovery): run a deep recursive scan of the codebase to map the “Ideal World” to the “Real World.”
  4. Step 3b - Spec Generation (Design): translate the refined intent plus discovery report into a surgical build spec.
  5. Execute one phase at a time.
  6. Require a gate before moving to the next phase.
  7. Verify success criteria before calling work complete.

Reliability phases

Step 3a: The Context Burst (Discovery)

The Scout (typically Gemini-CLI) performs a deep, recursive scan to discover existing patterns, utilities, and constraints.

  • Input: approved intent + selected implementation strategy
  • Output: discovery report mapping ideal architecture to real code conditions
  • Purpose: reduce hallucinations by grounding design in the current system

Step 3b: Spec Generation (Design)

The Architect (typically Claude Code) takes the refined Intent and Discovery Report and writes a surgical instruction set in specs/SPC-XX-spec.md.

  • The spec is explicit enough that a Builder can follow it blindly.
  • Each step includes file touchpoints, order of operations, and test gates.
  • This creates reliable handoff between planning and implementation.

What this gives you

  • Faster shipping with fewer rework loops
  • Better architectural consistency across sessions
  • Stronger accountability when defects appear
