Design
Define role & scope
Service-based businesses don't need more software. They need a workforce. Agent OS is the framework we use to design, build, and deploy AI agents that run real operations — sales, marketing, ops — without supervision.
Agent OS — the Agent OS — is how Brand75 designs autonomous AI workers that go beyond chatbots. Each agent has identity, capabilities, rules, knowledge, and a heartbeat. Together they form an organization with reporting lines, accountability, and verifiable output.
It's not a product. It's a methodology, proven across our own agency operations and now packaged for service businesses ready to scale without hiring.
Every agent in an Agent OS team is built from the same five primitives. Click any card to expand.
Who the agent is, what scope they own, and where their authority ends.
The exact tools, paths, and commands the agent can use to act on the world.
The constraints, reporting format, and verification protocol every agent must follow.
Domain-specific reference material the agent loads on demand.
The recurring tasks that keep the agent moving without being asked.
No agent goes live without clearing every phase. Click a phase to see what happens inside it.

Strategy defines the agent before a single file is written. We answer: what business outcome does this agent own, what's the smallest scope that delivers it, and what would success look like in 30 days?
This is the actual agent org chart powering Brand75 operations. Click any agent to see their role — or watch how a real task flows through the team below.
These rules ship with every Agent OS agent. They're the difference between an LLM that hallucinates and an agent you can trust to act unsupervised.
An agent never claims a task is done. It re-reads the file, runs the check, queries the API, then reports. Trust comes from evidence.
No "I'm going to start by…" filler. Agents lead with action and report results. The diff is the proof, not the prose.
Every non-trivial run writes a structured log entry. Future runs read it. The team learns instead of repeating mistakes.
task_id · status · result · blockers · next_step. Five fields, every time. Parsing is easy and escalation is automatic.
STARTED · COMPLETED · BLOCKED · ESCALATED · DELEGATED. Five states, no ambiguity. The orchestrator routes based on these alone.
Each agent declares its own model identity. Routing changes propagate to the agent's self-report. No drift, no surprises.
Autonomous systems fail. The framework's job is to make every failure visible, fast.
| Failure Mode | How It Shows Up | The Fix |
|---|---|---|
| Hallucinated completion | Agent reports COMPLETED but artifact is missing | Verify-before-report + Ryan audit pass |
| Context overflow | TOOLS.md or AGENTS.md exceeds 10K chars | Auto-cap with overflow into PROTOCOLS.md |
| Silent rate-limit | Model 429s mid-task, agent hangs | Health monitor failover to fallback chain |
| Scope creep | Agent acts outside SOUL.md authority | Hard boundaries in identity + escalation |
| Stale knowledge | Memory says X exists, X was renamed | Verify-before-recommend on every memory hit |
| Cascading failure | One agent breaks, queue backs up | Heartbeat health checks + isolated retries |
Agent OS isn't a slide deck — the agents above run on real infrastructure that's already in production. Here's the stack underneath them.
Any irreversible action — production deploys, payments, outbound posts, data destruction — is held in a pending queue with a Discord ping. Nothing ships until the human owner approves. A separate daily reconciliation job audits the upstream system independently, so bypassed approvals get caught after the fact.
Every agent session is shipped as a trace with tool calls, fallbacks, and per-axis quality scores. Engineering view for debugging, executive view for cost, quality view for the critic. Sidecar pattern — no runtime patches — so it survives every upgrade.
What happened (sessions), what is known (durable facts), and how to do things (recipes). Every entry is tagged by source so agent inferences never get retrieved as ground truth. A pre-compaction watcher rescues durable facts before they fall off the context window.
Sage scores every user-facing output against an LLM-as-judge rubric — factual accuracy, citation accuracy, completeness, source quality, tool efficiency. New recipes only enter procedural memory if Sage clears them at 0.7 or higher.
Each agent has a seed task set scored per rubric axis. Production traces that fail the critic become new eval cases. The suite gets stricter the longer the team runs — drift gets caught, not absorbed.
Code, prompts, durable memory, and auth profiles snapshot together every night with 14-day retention. Rollback is holistic — a bad prompt change doesn't outlive itself. Recovery from any single day is one command.
Agent OS works because it borrows from how real organizations are built — clear roles, written rules, accountability loops — and translates them into structures an LLM can actually follow.
Each agent owns a domain end-to-end. Prompts vanish on cold start; roles persist across sessions, models, and weeks.
The team's truth lives in version-controlled files. Memory drifts. Files don't.
Every agent action produces a check the next agent (or human) can audit. Trust scales because evidence scales.
Add a new agent in days, not weeks. The framework is the same. The role description changes.
The owner approves scope, reviews escalations, and shapes strategy. Agents handle the work, not the judgment.
Agencies, law firms, consultancies. Anywhere repeatable knowledge work eats founder hours, Agent OS gives that time back.
Brand75 designs and deploys Agent OS agent teams for service businesses. We start with a single agent, prove it pays for itself, then scale.
