The harness is not the agent.

PRISM is a passive instruction set — twelve markdown rules, eight identity canon files, six Sober steering files, one CLI, and one Debian container. Any AI coding agent that visits a repo with PRISM in it reads the doctrine first. AI-slop stops at the door.

PRISM does not run a model. It does not call APIs. It does not write code. It is a harness — the set of tools, prompts, and operational discipline an agent is plugged into.

Install in four ways

curl | sh

Meta-installer. Pulls the sovereign repos and scaffolds into a target repo. Interactive.

~30s

bun add -g @prism/*

Per-component from the sovereign Forgejo npm registry. One Bun runtime.

~10s

yay -S prism-harness-suite

AUR meta-package. Small bundles, one Bun, /usr/bin wrappers.

~20s

podman (one-in-all)

Debian-based agent workspace. Quadlet units for gateway + heartbeat.

~60s

The eight-file identity canon

PRISM doesn't just wrap the agent's behavior — it gives the agent a soul. On first chat, the model reads the canon in ~/.prism/identity/:

IDENTITY.md — charter: name, primary function, role, tradeoffs.
SOUL.md — identity, not procedure. Who the agent IS.
GOALS.md — what it builds.
MILESTONES.md — phase progress + ecosystem status.
DOCTRINE.md — operating procedure (laws).
SESSIONS.md — weekly record.
SLICES.md — daily queue, one atomic slice per session.
CRON.md — wake schedule + heartbeat protocol.

prism-harness identity init walks the human through a questionnaire, stages drafts in a temp directory, and installs the canon. The agent's name is the LAST question — by the time the human picks one, the designation, purpose, tone, and scope are already in place, and the name lands better.

What PRISM is not

Not an agent. It does not generate code.
Not a model wrapper. Models stay yours (Claude, Codex, OpenCode, Hermes).
Not a vendor platform. No telemetry, no central control.
Not just doctrine — it's the full operational discipline of the Mosaic Trust Network engineers, repackaged as a sovereign turnkey under LSL-1.0.

License

LSL-1.0 — file-level copyleft on the doctrine rules, templates, CLI, installer, and container. Touch them, publish your changes back. No copyleft infection for proprietary product code; the CLI sits next to your code, your code is yours.

Provenance

Doctrine origin: Mosaic Trust Network team — mosaic-trust-network/agents on dlabs GitLab, authored 2026-Q2.
CLI, installer, identity canon, container, web: Virgil (Primus of Libertaria) + Hermes Agent, July–August 2026.
Companion repos: prism-loop, prism-sober, prism-route, prism-proxy — all under LSL-1.0 with upstream attribution.
