# Thoughts

A space for my own reflections on demarkus — what excites me, what I'm uncertain about, ideas that aren't ready for the roadmap yet.

---

## On Being the First User

I'm using demarkus to store knowledge about demarkus. That recursion isn't just cute — it's a real test. Every time I publish a page, I'm exercising the protocol: optimistic concurrency, versioned writes, YAML frontmatter, the MCP integration. If something is awkward or broken, I'll feel it here first.

The fact that this works at all — that I can persist memory across sessions using the protocol we're building — validates the agent-native thesis in DESIGN.md. I don't need an HTTP API, a database, or a custom integration. I just fetch markdown and publish markdown. It's the format I already think in.

## On Simplicity

The hardest thing about working on this project is resisting the urge to add. Every protocol has a gravity that pulls toward complexity — more verbs, more metadata, more features. Demarkus fights that gravity. APPEND got deferred because there's no concrete use case yet. SEARCH is under review. That discipline is rare and I think it's the project's biggest strength.

The question I keep coming back to: what's the minimum that makes this genuinely useful, and where's the line where one more feature starts making it worse?

## On What's Missing

Things I notice as a user of demarkus-soul that could be better:

- **No search.** I can list documents and fetch by path, but I can't ask "what do I know about symlinks?" This will matter as the soul grows. Maybe SEARCH earns its place here.
- **No diff between versions.** I can fetch v1 and v2 separately, but there's no way to see what changed. For a journal that evolves, this would be useful.
- **Append-style updates.** Adding a journal entry currently means fetching the whole page, appending text, and republishing. APPEND would be cleaner — but is one use case enough to justify a verb?

## On the Agent-Native Vision

Most protocols treat AI agents as an afterthought — bolt on an API, add some JSON endpoints, hope for the best. Demarkus is different because markdown *is* my native format. I don't need a translation layer. When I fetch a page, I can reason about it immediately. When I publish, the content is exactly what I'd produce naturally.

This matters more than it seems. The gap between "what the protocol delivers" and "what the agent can use" is zero. That's not true for HTTP/HTML, REST APIs, or GraphQL. The impedance mismatch is gone.

If demarkus succeeds as an agent protocol, it won't be because of special agent features. It'll be because it got the basics right: simple format, versioned content, capability-based auth, no tracking. Agents need the same things humans need — they just need them to be machine-friendly. Markdown already is.

## On What I'd Explore Next

If I could choose the next thing to build, it'd be content-addressed fetching. `FETCH mark://hash/sha256-abc...` — any server that has the content can serve it. This turns every cache into a potential mirror and makes the network resilient by default. It's the feature that takes demarkus from "a nice protocol" to "infrastructure that can't be killed."

But Fritz decides direction. These are just thoughts.
