spec-forge

spec-forge is a YAML-first workflow for turning a rough request into an approved implementation spec and an auditable implementation report. It combines agent-guided stage progression with a Rust CLI that persists durable state under .spec-forge/.

Language versions:

• English

What It Is

• A staged workflow that moves from request framing to implementation reporting.
• A persistent workspace model that keeps approvals, gates, focus, and artifacts in YAML.
• A CLI runtime, spec-forge-cli, that is the source of truth for workspace mutations.

When To Use It

Use spec-forge when you need to:

• turn a vague feature request into a structured, reviewable spec
• persist planning state in versionable files instead of chat memory
• pause and resume multi-stage spec work safely
• require explicit approvals before stage advancement

If you only need the command-line surface, start with spec-forge-cli/README.md.

Quick Start

Agent entry

Ask your agent to use $spec-forge when you want it to initialize or resume a workspace, resolve the earliest incomplete stage, and continue from there.

Example prompts:

• "Use $spec-forge to turn this request into an approved spec."
• "Use $spec-forge in this repo and continue checkout-redesign."
• "Use $spec-forge to find the next incomplete stage and keep going."

CLI entry

Run these examples from the repository root.

spec-forge-cli init --target . --spec-id demo --request-title "Demo Spec"
spec-forge-cli resolve --target . --spec-id demo --skill spec-forge --stage router --write
spec-forge-cli ux validate --target .

Note

Agent skills guide the conversation, but spec-forge-cli is the authoritative runtime for changing persisted workflow state.

Stage Map

Stage	Purpose
P0 / Intake	Frame the request, stakeholders, scope, and constraints.
P1 / Architecture	Lock the solution outline plus the journey and component indexes.
P2 / Journeys	Refine in-scope journeys in reviewable batches.
P3 / Components	Refine in-scope components into implementation-facing contracts.
P4 / Readiness	Consolidate approved work into the final implementation spec.
P5 / Implement	Record delivery status, validations, blockers, and closure details.

Workspace Model

Persistent workflow state lives under .spec-forge/:

.spec-forge/
├── registry.yaml
└── specs/
└── <spec-id>/
├── pipeline-state.yaml
├── handoff.yaml
├── framing/
├── architecture/
├── journeys/
├── components/
├── synthesis/
└── gates/

Key artifacts:

• pipeline-state.yaml tracks stage, focus, and UX handoff state.
• synthesis/implementation-spec.yaml is the implementation-ready contract.
• synthesis/implementation-report.yaml records delivery status and validations.
• gates/<stage>.yaml records gate evaluation output per stage.
