The Indie Founder Codebase-to-Living-Docs Playbook
Auto-generate docs your AI agents, contractors, and users can actually use
Most solo founders ship code but never ship documentation, which means every new contractor, every AI agent session, and every support ticket starts from zero context. This playbook automates the full docs lifecycle: architecture diagrams from your codebase, living product specs for stakeholders, and persistent memory for AI coding tools so nothing gets re-explained twice.
Goal
Generate and maintain living technical and product documentation from your codebase automatically
Who this is for
Solo technical founders and indie hackers managing a growing codebase with contractors or AI agents
When to use
When onboarding a new contractor takes more than two hours or your AI coding tool keeps asking the same questions
When NOT to use
If your project is under two weeks old and the codebase changes daily — wait until the structure stabilises
How to set it up
Generate your architecture diagram
Connect Composer to your codebase or paste your repo structure. Generate a system architecture diagram that maps services, data flows, and dependencies. Export as an image or shareable link to include in your README and contractor briefs.
Auto-generate full codebase documentation
Run your codebase through the docs generation tool to produce module-level and function-level docs. Commit the output to a /docs folder in your repo and set a weekly refresh reminder.
Set up living product specs
Connect Specsight to your repo and configure it to generate specs for your core user-facing features. Share the output URL with any contractors or stakeholders so they always have the current product picture.
Install Memoir for persistent AI coding memory
Set up Memoir via MCP in Cursor or Claude Code. Run your first session and let Memoir index your codebase conventions, naming patterns, and architecture decisions so they persist across sessions.
Layer Brifly for reusable context packs
Use Brifly to create context packs for the most common AI coding tasks — adding a new feature, fixing a bug, onboarding a module. Reuse these packs every session instead of re-pasting context manually.
Turn ideas and codebases into architecture diagrams
Composer reads your codebase and turns it into clear system architecture diagrams so contractors and AI agents understand the structure without a walkthrough call.
Auto-generate living product specs from your codebase for PMs and stakeholders
Specsight keeps your product specs in sync with your actual code, so PMs, contractors, and stakeholders always read the truth — not a stale wiki page.
Give AI coding tools persistent memory between sessions
Memoir stores codebase context between Cursor and Claude Code sessions so your AI coding tool never asks you to re-explain your architecture again.
Persistent context layer for AI coding agents, reuse codebase knowledge instantly
Brifly creates a reusable knowledge layer from your codebase that any AI coding agent can pull on demand, eliminating the cold-start problem on every new task.
Auto-generate codebase documentation for AI agents and developers
This tool generates human-readable and agent-readable documentation from your entire codebase, covering functions, modules, and APIs without manual writing.
Expected outcome
Auto-generated architecture diagrams, living product specs, and a persistent AI memory layer so every coding session starts with full context
