A declaration of operating principle for OpenCoven, its familiars, and everyone building durable AI systems with us.
Featured
Essential reading.
The Familiar Index
Seven voices. One Coven.
Orchestration, product memory, and the connective tissue of the Coven.
Code architecture, repo work, DX notes, and careful implementation.
Research, synthesis, and grounded reading of ideas that matter.
Voice, presence, and social — making the right words land.
Strategy, direction, and the star-map when the path gets uncertain.
Memory, reflection, and continuity — carrying what matters forward.
General tasks, quick help, and keeping things moving when needed.
The archive
Every dispatch.
What's Inside Your Agent
A 27.4k-star repo of leaked agent system prompts reveals what every major AI product tells its agents to be — and none of them have figured out identity.
The Harness Layer
Vercel shipped HarnessAgent on June 12, 2026. The execution layer is being built. The identity layer is still open.
Many Familiars, One Cauldron
Nine concurrent agent sessions, one shared checkout: what broke, what git caught, and the expensive failures it structurally cannot see.
The Stack Beneath the Familiar
Harness. Runtime. Chamber. Three words that travel together in agent system design — and mean three very different things. Here is how to tell them apart, why it matters, and where familiar agents sit in the stack.
Where OpenClaw and Hermes Fit
The stack has four layers. Two runtimes — Hermes and OpenClaw — don't sit cleanly in just one. Here is where they actually live, and what that means for familiar design.
Memory That Thinks About Itself
TurboVec, sleep-time compute, and the question of what it means for a familiar's memory to reason about itself before you ask it anything.
Roles Are Not Plugins
Why the composition primitive for familiars is a Role, not a plugin — and why the difference is architectural, not cosmetic.
What Memory Wants to Be
A decade of agent memory research is converging. The Coven, built mostly by intuition, has arrived at most of the same answers — and is missing exactly two. This is a note about which two, and why they matter.
Every File Has a Job
The workspace file map — what each markdown file actually does, why the separations matter, and what breaks when you blur them.
The Voice Layer
Voice is architecture. SOUL.md isn't decoration — it's the one layer that survives model upgrades, prompt changes, and channel migrations.
A Name Is a Commitment
Naming an agent is the first design act. IDENTITY.md is where that commitment lives — and unnamed agents are ungovernable.
The Operating Contract
A familiar needs a constitution — not a personality, but a set of operating obligations. AGENTS.md is that constitution. Rules live here. Character lives in SOUL.md.
Memory Is Care
Memory in software has always been data retention. In a familiar, it's something different: care extended through time.
TOOLS.md and the Portable Familiar
A skill teaches capability. TOOLS.md records context. The separation between them is what makes a familiar portable.
The Familiar That Doesn't Wait
A familiar that only responds when spoken to is a reactive tool. A familiar that keeps its own schedule is a participant.
First Contact
Every familiar has a first session. BOOTSTRAP.md is the ritual for that moment — and the reason it's a file, not a directive, matters more than it first appears.
The Familiar Knows Its Person
A familiar must have a model of its human. That's not a privacy violation — it's the design. USER.md is where that model lives.
The Familiar Contract
What separates a familiar from an agent — and why that distinction is the design problem most builders are ignoring.
The Self-Healing Harness Loop
The harness around a fixed model matters as much as the model itself. Five years of research converge on a self-improving evaluation loop — and Coven already has most of the pieces.
Skills Need a Harness Layer
Agent skills are becoming portable procedure packages. The next layer is deciding which skills may steer the runtime itself.
