Tech Stack Documentation Agent

How the agent runs it

Agent reads GitHub repos, Terraform state files, Helm charts. Produces architecture diagrams, runbooks, and a changelog. Re-runs on every merge to main via webhook.

Who this is for

This is ideal for software engineers or DevOps professionals who've felt the pain of maintaining outdated architecture docs and have experience with APIs, GitHub, and infrastructure-as-code tools. You should be comfortable building integrations and automating documentation workflows—no need to be a full-stack expert, but hands-on technical experience with CI/CD pipelines and code repositories is essential. This suits you if you're already advising teams on best practices and want to productize that knowledge into a scalable SaaS offering.

Market opportunity

Engineering teams are drowning in technical debt around documentation; Gartner reports that 60% of engineering leaders cite poor documentation as a top blocker for team velocity. The shift toward infrastructure-as-code (Terraform, Helm) and GitHub-first workflows has made automated documentation parsing feasible and highly valuable. With AI-powered code reading now mature and companies increasingly willing to pay for single-source-of-truth architecture tools, timing favors early entrants in the automated documentation space.

Key risks

• → Security concerns with infra code access
• → Needs privacy policy / SOC2 story

Getting started

1. 1
   Build GitHub App prototype integration

   Create a minimal GitHub App that can authenticate, clone a test repo, and list files via the API. This validates the core authentication and repository access flow before building agent logic.
2. 2
   Test Claude API against sample codebases

   Feed Claude with a small Terraform file and a Dockerfile, then test its ability to extract and summarize architecture. This reveals token costs, hallucination risks, and whether Claude reliably parses infrastructure code.
3. 3
   Design webhook-to-documentation pipeline

   Map out how a merge-to-main webhook will trigger your agent, how results get stored, and where diagrams/docs land (e.g., Confluence, GitHub Wiki). Clear architecture here prevents costly pivots later.
4. 4
   Create Mermaid diagram generation template

   Write a prompt template that converts Claude's parsed infrastructure data into valid Mermaid syntax for diagrams. Test with 3–5 real-world infra configs to ensure reliability and visual clarity.
5. 5
   Launch closed beta with 3–5 early customers

   Find 3–5 engineering teams (via your network or cold outreach) willing to test free or discounted access. Gather feedback on pricing, documentation format, and feature priorities before full launch.
