Codex keeps Claude in check

In this blog post I detail the rapid development of an agentic engine designed to transform a standard AI chat tool into a proactive business intelligence platform. By integrating Anthropic’s Claude Agent SDK, I
successfully automated complex financial reporting tasks that traditionally required manual human prompts. The project highlights a collaborative "two-AI" workflow where Claude acted as the primary developer and Codex served as a rigorous technical reviewer, catching critical architectural flaws. To ensure data integrity, the system utilizes frozen Zod schemas and deterministic tools, preventing the AI from hallucinating sensitive financial figures. The narrative concludes with a successful live deployment, demonstrating how autonomous browser testing and strict contract boundaries can reliably deliver enterprise-grade automated insights.

How I Built a Full BI Platform With AI Because SAP Wanted Seven Figures to Upgrade

This month I published a few blog posts about my journey in building an enterprise financial planning and business intelligence platform, completely solo, with the help of AI: Claude Code and Codex.

And I'm not even a developer! I'm actually a GM running a full technology business and the last time I actually wrote code was back in 2010 when I was a principal software engineer :)

Please check out my posts, and feel free to drop comments on my blog.

I built a “Steam Workshop” for system architecture + product roadmaps + org blueprints (runs in your browser)"

Have you ever wanted to install the architecture of a product the way you install an app?

Not just a diagram, but the whole system architecture blueprint:

services and dependencies
teams and ownership
goals → initiatives → work packages
a 3-year planning horizon for product managers
plus a “prompt pack” so you can remix it

That’s what I’ve been building as a hobby project: SMT (Software Management & Planning Tool).

And this week I shipped something I’m genuinely excited about:

The Community Blueprints Marketplace (with social features)

You can now publish blueprint packages publicly, and the community can:

browse and install them
star them
comment / discuss them
see what’s trending (social proof + discovery loops)

Think: Figma Community / Steam Workshop, but for product architecture + product/team organization.

What’s a “Blueprint” in SMT?

A blueprint is a portable package (JSON) that contains:

a manifest (title, summary, tags, trust label, etc.)
a prompt pack (seed + variants like MVP/Scale)
a full system snapshot (teams, services, goals, initiatives, work packages)

The goal is learning through interaction:

install a blueprint
explore its org + architecture + roadmap in the app
remix it into your constraints
publish your remix back to the marketplace

Why I’m doing this

Most “reference architectures” online are:

static
divorced from org/team realities
not easily remixable
missing the roadmap/execution story

SMT tries to make “how a product might actually run” tangible:

architecture + org design + planning are all connected
you can poke at it, not just read it

SMT makes it possible for you to inspect any type of tech platform. Think LeetCode interview preps but for system design, architecture, team topologies, product roadmaps and software delivery planning.

Local-first by default (privacy + zero friction)

SMT is intentionally local-first:

it runs as a static app in the browser
your systems stay in your browser unless you explicitly publish a blueprint package

The cloud marketplace is optional and only powers:

public publishing
discovery
stars/comments

No “workspace sync” SaaS lock-in.

How the social marketplace works (simple + cost-free)

To keep this sustainable on the free tier, the backend is:

Cloudflare Workers + D1 (SQLite)
token-normalized search (no paid search / no vector DB)
GitHub OAuth for identity (scope: read:user only)

Important security bit:

public publishing does secret scanning (manifest + full system payload) and blocks likely API keys/tokens.

Try it (and please break it, it's a WIP hobby project)

1) Open the app

2) Explore the “Community Blueprints” view

browse the curated catalog
click Preview on anything that looks interesting
install an Available blueprint and inspect it across:
- System Architecture Overviews
- Org Design
- Roadmap & Backlog Management
- Year Plan / Detailed Planning

3) Publish + socials

in the publish flow, use Publish Publicly
then open Preview on your published blueprint:
- Star/Unstar it
- Post a comment
- sanity check that it’s discoverable via search

If anything fails, I want to know. Use the Feedback feature to log issues.

What I’d love feedback on (high signal)

Does the blueprint concept actually help you understand a product faster?
Are the “prompt packs” useful, or just noise?
What should “trending” mean here: stars, downloads, recency, or something else?
What social features would make this fun without turning it into a moderation nightmare?

If you want to contribute

This is open source (CC0) and I’m happy to collaborate.

Repo: https://github.com/khanmjk/altsoftwareplanning
Issues / PRs welcome: docs, UX polish, seed blueprints, moderation workflows, “remix lineage”, collections, reputation, etc.

Roadmap ideas (if the community likes this)

Remix lineage: “Forked from…” + remixes graph
Lightweight contributor reputation (badges, trust tiers)
Reporting/flagging + moderation queue
Curated collections (“Backends 101”, “B2B SaaS starters”)

If any part of this sparks your curiosity, I’d love for you to try it for 5 minutes and tell me what confused you, what felt magical, and what felt pointless.
