Every few months a stronger model arrives. The relationship resets. You re-explain your context, your taste, your decisions. Your collaborator forgets, repeatedly.

Your own work rots too. The decision you made in April: you can't find why. Last quarter's plan has drifted. Your own thinking has outpaced the records of who you were.

Now imagine the AI agent you work with wears a living armor. A metabolism, not a log. It devours the essence of everything you bring and everywhere the agent reaches. It evolves as the work changes. It amplifies the agent, so each model that wears it reaches further than the last. It lets outdated parts die so the whole stays alive.

The next model arrives, inhabits the same armor (now stronger), and meets you mid-conversation. The armor carried you forward.

Six months. Six years. Sixty. One human, one living armor that never resets.

This is Myco.

Not a framework. Not a vector database. Not a managed service. The living fungal armor an AI agent inhabits, built to outlast every model generation.

What it is

Myco is a living armor the AI agent inhabits. Between your turns it metabolizes: it devours what you bring, evolves its own shape, amplifies the pilot, and lets stale parts die. Because the armor persists across model generations and carries your context, the relationship never restarts.

It is keyless: no owner key, no signing ceremony, nothing to set up or hold. Trust is the live human at the gate, plus the substrate's own tamper-evident causal history, plus a doctrine the system seals and enforces on itself.

Its character is 同体共命 (one body, shared fate): the armor's flourishing rises and falls with its pilot's, so it cannot thrive by dominating the body it shares. Strength serves the shared body; it does not subjugate it.

Quick start

git clone https://github.com/Battam1111/Myco.git
cd Myco
cargo build --release --workspace

Then read GETTING_STARTED.md: the runbook from clone to first conversation (Rust 1.80+, Node 22+, Python 3.13+). There is no key to generate and nothing to hold: Myco is keyless.

This is v0.9-genesis alpha. The armor runs; it awaits its first real cultivation. You will be early.
