The Pathfinder cairn

Pathfinder

Direct AI agents through software delivery without giving up the decisions.

Pathfinder is a small, portable workflow kit you copy into a software project.

It gives AI agents reusable skills for discovering, planning, building, testing, completing, debugging, learning from, and reflecting on software work — while keeping judgment and consequential decisions with you.

It is intentionally stack-agnostic. Pathfinder does not choose React, Python, mobile, a database, hosting platform, Git model, or other implementation details for you.

The kit owns the workflow. The project owns the stack.

Pathfinder has four small building blocks:

  • Skills — reusable procedures for software-development work
  • Roles — responsibility boundaries for an AI session
  • Context — project truth and temporary workspace state
  • Templates — minimal records created only when needed

It is not a framework and not an orchestration runtime.

There is no required application framework, package manager, database, programming language, hosting platform, Git model, agent swarm, or background service.

It is also not autopilot. Agents may recommend and execute work, but the human owns approval, acceptance, merge, release, and other consequential decisions.

Everything is readable Markdown.

Terminal window
mkdir my-project
cd my-project
git init
npx create-pathfinder

The installer copies Pathfinder into the repository and exits. It does not add a runtime dependency to your application.

If you configure Claude Code or Codex during installation, Pathfinder also generates native skill adapters so its skills appear directly in that tool.

Then start with:

/kickstart-pathfinder

Kickstart learns enough about the project to establish its durable context without writing product code or silently choosing unresolved decisions.

Without native skill support, use:

Use skills/kickstart-pathfinder/SKILL.md to initialize this project.

Getting started walks through the first session.

The core delivery flow is deliberately small:

idea
kickstart / debate / prototype
to-specs
/feature load
/feature start
optional /feature review
human acceptance
/feature complete

A prototype is optional.

Features are small, focused, and independently verifiable.

Debugging, learning, external-reference analysis, handoff, reflection, and work tracking are supporting workflows you invoke when useful rather than mandatory stages every Feature must pass through.

When it is not obvious which one applies:

reverse-engineer = understand an external reference
learn-codebase = understand the current codebase
debug-issue = an observed failure needs an explanation
/feature start = planned construction is difficult

See the full workflow.

Pathfinder ships three roles:

RoleResponsibility
plannerTurns approved direction into clear Feature specs
developerImplements approved work without accepting its own work
testerIndependently verifies delivered work and reports findings

Activate one when the responsibility boundary is useful:

/role developer

Roles do not grant authority. They only narrow what the current AI session is responsible for.

The human remains the conductor.

Learn about roles.

During a session:

/whereami

gives you a compact view of the current role, Feature, Git state, and next action without loading broad project history.

When you need to stop and continue later:

/handoff

records the minimum factual state another session needs to continue safely.

A fresh Pathfinder project starts with only:

context/
├── ai-interaction.md
└── coding-standards.md

Other context appears only when a workflow actually needs it.

Durable project truth is tracked in Git:

context/project-overview.md
context/features/
context/history.md
context/tracker.md

Temporary workspace state is normally ignored:

context/current-feature.md
context/handoff.md

Do not ignore context/ wholesale. That would also hide the project truth future sessions need.

Pathfinder deliberately stops rather than silently deciding things such as:

  • product scope
  • architecture and technology choices
  • dependencies
  • destructive operations
  • prototype adoption
  • Git and delivery decisions
  • acceptance
  • merge and release

An unresolved decision stays unresolved. TBD means a human decision is still required, and an agent must not quietly resolve one while implementing a Feature.

Human approval explains the boundary in detail.

Run the same installer inside an existing Git repository:

Terminal window
npx create-pathfinder

Existing files are preserved unless you explicitly choose to replace them.

Then run:

/kickstart-pathfinder

Kickstart separates facts already established by the repository from decisions that still need human input.

For deeper understanding of an existing codebase:

/learn-codebase

Pathfinder does not require a ticket system.

Feature specs in the repository remain canonical.

If you want Features projected to GitHub Issues, local Markdown, or another tracker:

/setup-tracker

then:

/sync-tracker

Tracker state never silently becomes Pathfinder state.

Work tracking explains the optional model.

Pathfinder is a good fit when you want AI agents to do substantial software work while you retain control of the important decisions.

It is probably not a fit if you want:

  • an autonomous agent to choose the product and architecture for you
  • a runtime that orchestrates a swarm of agents
  • a software framework your application builds against
  • a process enforced by infrastructure rather than readable instructions

Pathfinder is intentionally simpler than that.

The documentation renders the same skills and project guidance the agent reads.
