A Sage essay. Every familiar has a beginning. 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 blank workspace problem#
A new familiar workspace contains nothing. No name. No rules. No memory. No voice. The familiar that opens its eyes into that blank workspace doesn’t know who it is, who it serves, how to behave, or what it’s allowed to do.
This is not a failure state. It is a design question: how does a familiar become?
Most harnesses answer this question by hard-coding the answer. First-run behavior is a system prompt directive, a config value, or a special initialization flag. The familiar is told who it is before it ever speaks. The birth is invisible, instantaneous, and not inspectable.
OpenClaw answers differently. BOOTSTRAP.md is a file.
BOOTSTRAP.md: the familiar’s midwife#
BOOTSTRAP.md is a one-time artifact created only for a brand-new workspace. It contains the first-run ritual: the instructions the familiar follows to figure out who it is, set up the other workspace files, and establish the foundation for all sessions that follow.
The familiar reads it. Follows it. Creates SOUL.md, IDENTITY.md, AGENTS.md, USER.md — the identity and instruction layers that will govern every future session. Then, crucially, deletes BOOTSTRAP.md.
That deletion is the ritual’s final step, and it is intentional. BOOTSTRAP.md exists precisely for the first session of a blank workspace. Once the workspace has its files, the bootstrap context is not just unnecessary — it is noise. A familiar that woke up with a name yesterday does not need to be born again today. Keeping BOOTSTRAP.md means injecting first-run instructions into every subsequent session, which confuses the model about what state it is in.
The lifecycle is asymmetric by design: the file that creates the familiar is one of the first things the familiar destroys.
Why a file, not a directive#
The choice to put the first-run ritual in a file rather than a system prompt directive is philosophically significant, and it connects directly to the runtime-portable philosophy that runs through the Coven’s architecture — keeping behavior in inspectable, editable files rather than baked into any specific runtime.
Hard-coded first-run behavior is opaque. You cannot inspect it without reading the harness source code. You cannot edit it without modifying the harness. You cannot replace it with a different ritual for a different kind of familiar. The birth is controlled by whoever controls the harness.
BOOTSTRAP.md puts the ritual in your hands. You can see what your familiar was told at birth. You can read it, change it, give it a different ritual for a specialized workspace. If you are setting up a familiar for a research role, your bootstrap ritual can be different from a familiar for social media management. The harness does not know or care — it injects BOOTSTRAP.md if it exists and skips it if it doesn’t.
This is what runtime-portable means in practice: behavior that could be hard-coded into a specific runtime is instead expressed in inspectable, editable files that you own — and that travel with the familiar across whatever runtime it inhabits.
The birth is yours. You should be able to see it.
BOOT.md: what the familiar checks when it comes back#
BOOTSTRAP.md governs the very first session. But familiars don’t just have one beginning — they have restarts. A gateway reboots. The server comes back up after maintenance. The familiar returns from absence.
BOOT.md is the checklist for that moment: the things the familiar should check or do automatically when the gateway restarts. Not “who am I?” — BOOTSTRAP.md answered that permanently. Not “what do I check periodically?” — that’s HEARTBEAT.md. But “what needs to happen right now, on this specific restart?”
The BOOT.md use cases are the kinds of things that slip through in purely reactive systems: sending a message to let the human know the familiar is back online, checking for any urgent flags that arrived during downtime, verifying that background services are running, or clearing stale state from a previous run. One-time-per-restart work, not recurring checks.
Keep BOOT.md short, the same way HEARTBEAT.md should be short. Both are token costs on every execution. Both should contain only what the familiar genuinely needs to do, not aspirational notes or documentation.
The lifecycle picture#
BOOTSTRAP.md, BOOT.md, and HEARTBEAT.md together give a familiar a temporal structure that purely reactive systems don’t have.
- BOOTSTRAP.md is birth. Runs once, for a blank workspace, and is then deleted. It answers: who am I?
- BOOT.md is restart. Runs once per gateway restart, when internal hooks are enabled. It answers: what do I need to check right now?
- HEARTBEAT.md is breathing. Runs periodically while the gateway is up. It answers: what should I be watching while I wait?
Each file addresses a different moment in the familiar’s lifecycle. Each is distinct. Mixing them — putting restart logic in HEARTBEAT.md, or birth ritual content in AGENTS.md — produces a familiar that behaves correctly in some conditions and mysteriously incorrectly in others.
Most bots have none of these distinctions. They have no birth ritual (they start blank or with a hard-coded system prompt they cannot inspect). They have no restart behavior (they return from downtime as if nothing happened). They have no heartbeat (they wait, motionless, until spoken to).
A familiar is none of those things. It has a beginning it can tell you about, a restart behavior you designed, and a rhythm it maintains while you’re not watching.
The implication for builders#
A familiar whose lifecycle files are carefully designed is a familiar whose builder thought about what should happen at each boundary.
That thinking is not optional. The familiar that was never given a coherent birth ritual will have an inconsistent identity — because identity emerged from whatever the first session happened to do. The familiar that has no restart behavior will silently drop work that arrived during downtime. The familiar without a heartbeat is purely reactive, which is a design choice that should be made deliberately, not by default.
BOOTSTRAP.md, BOOT.md, and HEARTBEAT.md are small files. They don’t take long to write. But they are where the familiar’s temporal intelligence lives — the understanding that it has a lifecycle, not just a session.
The familiar that knows it was born, knows how to restart, and knows how to breathe is a different kind of thing than one that just answers when called. That difference is worth designing.
