SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides an orchestrated framework to run, monitor, and document phase-based work across a project, turning scattered tasks into a disciplined, artifact-generating workflow.

Core Features & Use Cases

  • Orchestrates phases from clarify to report to produce sequential artifacts.
  • Manages phase prompts, artifact pipelines, and optional subagent integration.
  • Suitable for learning projects and codebases requiring structured phase progress tracking and evidence collection.

Quick Start

Run a phase harness session to initialize .harness/ artifacts and begin the phase flow.

FAQPage Schema
How do I orchestrate end-to-end project phase execution to produce progressive artifacts?

End-to-end project phase execution orchestrates sequential phases from clarify to report, generating progressive artifacts under .harness/ and docs/progress while enforcing non-committal harness state until release. It manages phase prompts and supports optional subagent integration for structured workflows.

What is structured phase progress tracking for codebases and learning projects?

Structured phase progress tracking is a disciplined workflow that turns scattered tasks into sequential artifact-generating phases. It applies to learning projects and codebases requiring evidence collection, running from clarify through plan and implement to report, documenting each step progressively.

How do I set up a phase harness session to initialize artifact pipelines?

To initialize artifact pipelines, run a phase harness session which creates the .harness/ directory structure and begins the phase flow. This sets up the orchestrated framework to manage phase prompts and collect evidence across the project lifecycle.

Can I use subagent integration for evidence collection in a phase-based workflow?

Subagent integration is supported for evidence collection within phase-based workflows. The orchestration framework manages phase prompts and artifact pipelines while optionally delegating tasks to subagents, ensuring artifacts are generated progressively under .harness/ and docs/progress directories.

Does phase work orchestration enforce non-committal state until release?

Phase work orchestration enforces non-committal harness state until release, ensuring generated artifacts under .harness/ and docs/progress remain isolated. This prevents partial or incomplete phase artifacts from affecting the main project state until explicitly released.

Best way to manage artifact pipelines from clarify to report phases?

Managing artifact pipelines from clarify to report requires an orchestrated framework that sequences phases and generates progressive artifacts. This approach manages phase prompts, supports subagent integration, and maintains artifact isolation under .harness/ and docs/progress until release.
