§ 02THE GAP

PROBLEM.

Six failure modes every team running agents in production has felt. AgentOS is built to make each one impossible.

INVISIBLE FAILURES

Step 3 broke. You'll find out tomorrow.

When a 4-agent pipeline fails at step 3, you need to see the exact handoff that broke — not grep through logs across services hoping to find a clue.

63%of multi-agent failures go undetected for 24+ hours
AgentHog captures full span trees — replay any failure exactly.
RUNAWAY COSTS

$4,000 bill. No idea which agent.

One agent quietly consumes 10× the tokens of every other agent combined. Your monthly bill tells you the total — but never which agent caused it.

#1reason agentic AI projects get cancelled by leadership
Per-agent, per-model, per-prompt cost. Alerts before finance notices.
DELEGATION LOOPS

A → B → C → A. $50 burned, no output.

Agent A delegates to B, B delegates to C, C delegates back to A. The cycle repeats silently, burning thousands of tokens with no output.

$50+burned in under a minute by a single undetected loop
Topology graph + cycle detection — kill loops the moment they form.
SILENT REGRESSIONS

Eval scores dropped. Users told you first.

A teammate updates a system prompt. Eval scores drop 23% overnight. Users start complaining about quality — your team finds out from support tickets.

3.2 daysaverage time to detect a prompt regression
Eval drift alerts on every deploy. Catch regressions before users do.
SHIPPING BLIND

"Seems better" isn't data.

Your new prompt seems better in manual testing. But 'seems better' isn't data. Without controlled experiments, you're gambling with production quality.

78%of teams ship prompt changes with zero statistical validation
Built-in A/B with Bayesian stats. Ship when the evidence is real.
SECURITY GAPS

PII leaked. Found out days later.

Your agents handle customer data, API keys, and sensitive information. A single prompt injection or PII leak can mean regulatory fines and lost trust.

7%of global revenue — EU AI Act fines start 2026
Inline scans at the syscall layer — block PII and injections before they ship.
§ 03HOW IT WORKS

ONE IMPORT.

One import. The entire platform — stdlib, isolated runtime, full observability, and security.

01

Integrate in 5 minutes

One import drops in the full platform — stdlib primitives, isolated process execution, span capture, and security scanning. No new infrastructure. Works with your current stack.

02

Get every layer

Typed memory and tool primitives. Bounded process isolation. Full span trees with cost per call. Eval scores against your goldens. PII and prompt-injection scanning — all wired together.

03

Deploy production-ready

Set SLOs on eval scores and latency. Runtime policy enforces tool allowlists. Cryptographic trace seals for audit. Replay any failure exactly. Ship knowing the whole stack is solid.

§ 04THE PLATFORM

FOUR PILLARS.

L01 · AUTHORING

AgentBuild

A standard library for autonomous software. Memory, tools, retries, and eval harnesses ship as primitives — not as code your team rewrites every quarter.

AgentBuild
DESCRIBE YOUR AGENT
BUILD →
STDLIB
Typed primitives for memory, tools, retries, planners.
TEMPLATES
Forkable starting points: research, support, ops.
DEPLOY.SPEC
Declarative manifest — one file from local to prod.
EVAL HARNESS
Goldens, replays, regression gates built in.
L02 · EXECUTION

AgentRun

A kernel for agents. Real process isolation, mediated syscalls, bounded memory, networked state. The runtime that makes "agent" mean something concrete.

PROCESS MONITORsyscalls: 1,847

KERNEL ACTIVE · 3 POLICIES ENFORCED
PROCESSES
Each agent run is a first-class isolated process.
SYSCALLS
Tool calls go through a mediated, audited interface.
MEMORY
Bounded, persistent, addressable per agent.
NETWORKING
Outbound is policy-controlled, not free-for-all.
L03 · OBSERVABILITY

AgentHog

Datadog for autonomous systems. Every span captured, every prompt versioned, every run replayable. Evals are first-class — not an afterthought.

TRACE · 58111,241ms · $0.0000

llm.complete943ms

TRACING
Span-level capture across tools, prompts, models.
REPLAY
Re-run any historical trace bit-for-bit.
EVALS
Goldens, drift, groundedness — graded on every commit.
MONITORS
SLOs and alerts that understand non-determinism.
L04 · SECURITY

AgentSec

Adversarial-grade security for agent stacks. Continuous red-teaming, runtime policy, and the only PII / prompt-injection scanner that runs inside the syscall layer.

SECURITY SCAN · trace_5811
scanning...
TRACE SEALED · SOC2-ALIGNED
RED TEAM
Always-on adversarial probes. Reports against goldens.
DEFENSE
Inline scans for prompt-injection, PII, credential leaks.
POLICY
RBAC and tool-allowlists at the syscall layer.
AUDIT
Cryptographic trace seals. SOC2-aligned.
§ 05ONE EVENT STREAM

Four pillars.
One event stream.

Every build artifact, runtime event, trace, eval score, and security event lands in one PostgreSQL table — with the same identity columns. Cross-cutting questions become one SQL query.

QUERIES OTHER STACKS CAN'T ANSWER
Cost per failed eval, by agent
Traces that triggered a security alert
Latency p95 after the last deploy
Eval drift since prompt v3.2 shipped

§ 06VS THE FIELD

Tracing tools end where AgentOS begins.

Langfuse, LangSmith, Helicone, Arize — strong observability surfaces, but the data lives in their silo. AgentOS gives you the runtime, the stdlib, security at the syscall layer, and one event stream you can query with SQL.
