Gsd To Autoforge Spec

Documents
gsd-to-autoforge-spec

Gsd To Autoforge Spec is an Agent Skill for documents published in the AutoForgeAI/autoforge repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Convert GSD codebase mapping to AutoForge app_spec.txt. This skill should be used when the user has run /gsd:map-codebase and wants to use AutoForge on an existing project. Triggers: "convert to autoforge", "gsd to spec", "create app_spec from codebase", "use autoforge on existing project", after /gsd:map-codebase completion.

QUICK START

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/AutoForgeAI/autoforge/blob/HEAD/.claude/skills/gsd-to-autoforge-spec/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/gsd-to-autoforge-spec, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

GSD to AutoForge Spec Converter

Converts .planning/codebase/*.md (GSD mapping output) to .autoforge/prompts/app_spec.txt (AutoForge format).

When to Use

  • After running /gsd:map-codebase on an existing project
  • When onboarding an existing codebase to AutoForge
  • User wants AutoForge to continue development on existing code

Prerequisites

The project must have .planning/codebase/ with these files:

  • STACK.md - Technology stack (required)
  • ARCHITECTURE.md - Code architecture (required)
  • STRUCTURE.md - Directory layout (required)
  • CONVENTIONS.md - Code conventions (optional)
  • INTEGRATIONS.md - External services (optional)

Process

ls -la .planning/codebase/

Required files: STACK.md, ARCHITECTURE.md, STRUCTURE.md

If .planning/codebase/ doesn't exist:

GSD codebase mapping not found.

Run /gsd:map-codebase first to analyze the existing codebase.

Stop workflow.

Read all available GSD documents:

cat .planning/codebase/STACK.md
cat .planning/codebase/ARCHITECTURE.md
cat .planning/codebase/STRUCTURE.md
cat .planning/codebase/CONVENTIONS.md 2>/dev/null || true
cat .planning/codebase/INTEGRATIONS.md 2>/dev/null || true

Extract key information:

  • From STACK.md: Languages, frameworks, dependencies, runtime, ports
  • From ARCHITECTURE.md: Patterns, layers, data flow, entry points
  • From STRUCTURE.md: Directory layout, key file locations, naming conventions
  • From INTEGRATIONS.md: External APIs, services, databases
cat package.json 2>/dev/null | head -20 || echo "No package.json"

Extract:

  • Project name
  • Version
  • Main dependencies

Create prompts/ directory:

mkdir -p .autoforge/prompts

Mapping GSD Documents to AutoForge Spec:

GSD SourceAutoForge Target
STACK.md Languages<technology_stack>
STACK.md Frameworks<frontend>, <backend>
STACK.md Dependencies<prerequisites>
ARCHITECTURE.md Layers<core_features> categories
ARCHITECTURE.md Data Flow<key_interactions>
ARCHITECTURE.md Entry Points<implementation_steps>
STRUCTURE.md Layout<ui_layout> (if frontend)
INTEGRATIONS.md APIs<api_endpoints_summary>
INTEGRATIONS.md Services<prerequisites>

Feature Generation Guidelines:

  1. Analyze existing code structure to infer implemented features
  2. Each feature must be testable: "User can...", "System displays...", "API returns..."
  3. Group features by category matching architecture layers
  4. Target feature counts by complexity:
    • Simple CLI/utility: ~100-150 features
    • Medium web app: ~200-250 features
    • Complex full-stack: ~300-400 features

Write the spec file using the XML format from references/app-spec-format.md:

cat > .autoforge/prompts/app_spec.txt << 'EOF'
<project_specification>
  <project_name>{from package.json or directory}</project_name>

  <prerequisites>
    <environment_setup>

  </api_endpoints_summary>

  <key_interactions>
    {from ARCHITECTURE.md Data Flow}
  </key_interactions>

  <success_criteria>
    <functionality>
      - All existing features continue working
      - New features integrate seamlessly
      - No regression in core functionality
    </functionality>
  </success_criteria>
</project_specification>
EOF
head -100 .autoforge/prompts/app_spec.txt
echo "---"
grep -c "User can\|System\|API\|Feature" .autoforge/prompts/app_spec.txt || echo "0"

Validation checklist:

  • <project_specification> root tag present
  • <project_name> matches actual project
  • <technology_stack> reflects STACK.md
  • <core_features> has categorized features
  • Features are specific and testable

Output:

app_spec.txt generated from GSD codebase mapping.

Source: .planning/codebase/*.md
Output: .autoforge/prompts/app_spec.txt

Next: Start AutoForge

  cd {project_dir}
  python ~/projects/autoforge/start.py

Or via UI:
  ~/projects/autoforge/start_ui.sh

The Initializer will create features.db from this spec.
