codd-assemble

name: codd-assemble description: | Assemble generated CoDD sprint fragments into a complete, buildable project. Use after all codd implement sprints have produced src/generated/sprint_N/ fragments and the design documents are ready to be integrated into final project files, entry points, source code, and configuration.

CoDD Assemble

Assemble generated sprint fragments into a complete, buildable project. This is the final step in the greenfield pipeline after codd implement.

Usage

Use this skill after all sprints have been generated via codd implement. The assembler reads design documents and generated code fragments, then invokes AI to produce a unified project with all configuration files, entry points, and source code.

Prerequisites

1. codd implement has been run for all sprints.
2. Generated fragments exist in src/generated/sprint_N/ directories.
3. Design documents exist in docs/ with valid frontmatter.

Workflow

# Basic usage — assembles into src/
codd assemble --path .

# Custom output directory
codd assemble --path . --output-dir app

# Override AI command (e.g., use a different model)
codd assemble --path . --ai-cmd 'claude --print --model claude-opus-4-6 --tools ""'

What It Does

1. Collects all design documents (architecture, component design, state management, etc.)
2. Collects all generated code fragments from src/generated/sprint_N/
3. Builds a prompt with both design context and code fragments
4. Invokes AI to produce a unified project:
   • Project configuration: package.json, tsconfig.json, next.config., tailwind.config., etc.
   • Entry points: app/layout.tsx, app/page.tsx, globals.css, etc.
   • Source code: components, utilities, types, hooks, reducers
5. Parses === FILE: path === blocks from AI output and writes files

Output

Files are written relative to the project root. The assembler produces both:

• Configuration files at the project root (package.json, tsconfig.json, etc.)
• Source files under the output directory (default: src/)

HITL Gate

After assembly, verify the project builds:

# For Node.js/TypeScript projects
npm install
npm run build

# For Python projects
python -m pytest

If the build fails, check:

• Missing imports between assembled files
• Configuration mismatches (TypeScript strict mode, module resolution)
• Framework-specific entry point conventions

Integration in Full Pipeline

#!/bin/bash
set -e

codd init --requirements spec.md
codd plan --init

waves=$(codd plan --waves)
for wave in $(seq 1 $waves); do
  codd generate --wave $wave
done

codd validate

sprints=$(codd plan --sprints)
for sprint in $(seq 1 $sprints); do
  codd implement --sprint $sprint
done

# Final step: assemble fragments into a working project
codd assemble

Troubleshooting

• No generated fragments found in src/generated/
  • Run codd implement first. Fragments are created per sprint.
• Build fails after assembly
  • Check that the design documents specify the correct framework and configuration.
  • Re-run with --ai-cmd pointing to a more capable model (e.g., Opus) for better integration.
• Missing configuration files (package.json, tsconfig.json)
  • The assembler prompt explicitly requests these. If missing, re-run assembly.

Guardrails

• Always verify the build after assembly.
• Do not manually edit assembled files before verifying the build — establish a clean baseline first.
• If the assembled output is unsatisfactory, fix the design documents or implementation plan and regenerate, rather than patching assembled code.
