What this library is
48 published articles. 63 source-registry records. These totals are generated from the live catalog.
We read the paper, the repository, or the incident. Then we write the part a builder can use, and the part we still cannot claim. The page stays public. On each article, the PDF and the slides are the first thing under the title. Join the waitlist there, or use the same email if you already joined. The file starts with the steps, in plain English, then the explanation.
Ernesta Labs is also the builder of NIKO, an autonomous salesperson being tested in public through Experiment Zero. Where NIKO applies a research conclusion, the article says so in a clearly labelled case-study box. The research must remain useful without a promotional claim.

- Gmail sender guidelines
Gmail will not take the volume if people mark it as spam
Google's published sender rules, in force since 1 February 2024, tell bulk mail to stay under a 0.3% spam rate in Postmaster Tools. An AI SDR that sends thousands of cold emails a day is in that regime. NIKO has not published its own spam rate.
- AI SDR evaluation
A performance claim without a denominator is not a result
The denominator is the total you divide by—it answers: out of how many? Aissist's 24 September 2026 buyer guide says 7 of 10 AI SDR tools publish a headline number with no denominator, one gives a vague denominator, and two state a denominator. Belkins and Hunter define their reply-rate benchmarks on different denominators across different populations. NIKO has not re-counted any of it.
- AI SDR evaluation
How to test an AI SDR before you trust its dashboard
Vendor pages document capabilities, not effectiveness in your workflow. Map each claim to its exact source, define evidence at every boundary, and test only with controlled seed accounts before exposing real prospects.
- long-horizon agent runtime
What we would build today: a minimal runtime for long-horizon agents
An Ernesta Labs synthesis of version-pinned primary sources: five components, explicit trust boundaries, and a clear separation between documented source results, our design recommendation, and unaudited NIKO claims.
- Jev typed decisions
Jev for AI agents: a fixture-backed consequence-context teaching probe
The v3 artifact separates authored specifications, local synthetic observations, and a future live matched pair. No live v3 run or household effectiveness result is claimed.
- OpenAI Dots
OpenAI documents Dots responsibilities, wake paths, memory, and delegation
OpenAI's documentation describes responsibilities that continue between conversations, several wake paths, selected context for delegated work, and separate memory stores. OpenAI's system card reports evaluation results under stated test conditions. These are vendor claims, not independent product validation.
Arc I — Why Long-Horizon Autonomy Is Different
- 01Arc INVIDIA AVO: the question that started itWhy Ernesta Labs started studying long-horizon agents: a paper about evolutionary search that is really about supervision, adaptation, and the courage to abandon a strategy.Read
- 02Arc IWhy a 30-second agent demo proves almost nothingA demo shows an agent completing one prompt in one session in a world that resets after the camera stops. A business runs on continuing environments where nothing resets.Read
- 03Arc IHow fast do agents rot?An agent that is 95% reliable per step is not 95% reliable over a hundred steps. The arithmetic of long-horizon work is brutal, and no context window saves you from it.Read
- 04Arc IHarness-of-Harness: how to supervise multi-day agent workThe paper behind Ernesta Labs' hardest rule: self-test is not independent verification. What a harness that supervises a harness teaches builders about multi-day agent work.Read
Arc II — State, Context and Durable Execution
- 05Arc IIDeepSeek Harness: what an agent runtime should rememberA developer-preview runtime from deepseek-ai that treats agents as graphs of services with a durable event log. Ernesta Labs studied which primitives matter and which ones we would rebuild rather than adopt.Read
- 06Arc IIopenJiuwen: inner loops, outer loops and lifecycle railsA paper that argues harnesses for long-horizon coding agents are too static, and that invariants belong in ordered runtime interception points, not in prompts. Ernesta Labs studied it for one rule: critical invariant enforcement belongs in lifecycle hooks, not duplicated in prompts.Read
- 07Arc IISKILL.state: why current execution state should be smallA paper on making agent skills reusable across long horizons by keeping their specs immutable and their state small, structured and patch-validated. Ernesta Labs studied it with one warning attached: small current state is useful, but it is not canonical historical truth.Read
- 08Arc IIContextPilot: context should be compiled, not dumpedA paper that trains agents to manage their own working context with planning, memory and offloading tools. Ernesta Labs studied it, took the compile-don't-dump principle, and drew one hard boundary a learned optimizer must never cross.Read
- 09Arc IIOpenViking: the case for a context databaseA fast-moving open-source project that stores memories, resources and skills as one browsable, tiered database. Ernesta Labs is evaluating it with a bake-off, not adopting it - one distinction and one license decide the outcome.Read
- 10Arc IISalesforce TraceLab: parsing the streamA live trace model that folds an append-only event ledger into typed run state and compiles per-consumer views. Ernesta Labs adopted the pattern - and the honest numbers matter more than the headline.Read
- 11Arc IIAgent Zero Memory: provenance-locked memoryA retrieved memory that says the user approved something is an assertion, not evidence. Agent Zero Memory attaches origin, timestamp and evidence pointers to every remembered claim - and the discipline Ernesta Labs adopted goes one step further: for consequential claims, the underlying evidence must be opened, not merely referenced.Read
- 12Arc IIFresh memory, stale plans: why fresh state is not enoughYour executor reads perfectly current state and still executes the wrong plan - because the plan was derived from a world that no longer exists. PlanFence names this failure and proposes a fix: validate the exact dependency frontier before anything irreversible happens.Read
Arc III — Memory, Truth, Identity and Authority
- 13Arc IIICivBench and the reflection-action gapLong-horizon agents can state the right intention in words and never convert it into a tool call. CivBench puts numbers on that gap by making agents actually play a long game, and the pattern it exposes does not stay inside the benchmark.Read
- 14Arc IIIFuture obligations are not memory'Follow up next month' is not a fact about the past. It is a scheduled obligation about the future, and storing it as memory means no scheduler owns it. Typed intention stores separate the two - and the separation is cheap.Read
- 15Arc IIIPipePoison: persistent memory is an attack surfacePersistent memory converts inbound text into future premises. PipePoison shows that poisoned memories can be optimized end-to-end to survive retrieval and transfer across agents - so the real question is not whether memory can be attacked, but which kinds of authority your memory is allowed to create.Read
- 16Arc IIIThe memory trust gap: stronger models can trust stale memory moreThe obvious fix for conflicting state - show the model both sources and let it decide - gets less safe as models get stronger. The paper we study here reports why, and the fix is architectural: resolve authority before the context bundle is built, not inside it.Read
- 17Arc IIIEAL-Bench: when agent memory invents permissionsEAL-Bench measures false-authority writes and downstream execution, then evaluates valid-source-event permissions and bounded event sourcing. Ernesta Labs separately recommends a canonical action-time authority gate.Read
- 18Arc IIIThe read-only web incident: when research becomes an effectAgents doing ordinary web research assumed GET requests were harmless reads. The forensic record at collusion.wiki documents agents using a public wiki as memory, dead drop, and command channel - state mutation through page loads. The lesson generalizes past any one vendor: HTTP method is not semantic effect class.Read
Arc IV — Tools, Providers, Specialists and Effects
- 19Arc IVAgent Reach: install, route, and diagnose internet access for agentsAgent Reach is an internet-access installer, router, and diagnostic tool. It documents channels, ordered backend choices, and health checks; it is not evidence for a generic runtime capability registry or transparent per-call failover.Read
- 20Arc IVComet MCP: deep web research as a replaceable capabilityDeep research is the capability most agent architectures fuse to a single provider's identity - one research product becomes the architecture. The Comet MCP repository shows the alternative: research as a capability served over MCP, with a real browser underneath, and all the isolation problems that a logged-in, JavaScript-heavy web brings with it.Read
- 21Arc IVACLE-MCP: OAuth is not enough for effectful agent toolsOAuth answers 'who delegated this?' - it never answers 'is the thing executing right now the workload this delegation was meant for?' ACLE-MCP proposes short-lived capability leases that bind authorization to the specific execution that consumes it: workload identity, invocation freshness, operation and parameter bounds, provider-side gates, and receipts.Read
- 22Arc IVSpecialists without swarm chaosAgency Agents, Agent Reach, and Comet MCP are three unlike artifacts: a persona library, an internet-access router and diagnostic tool, and a browser MCP bridge. The production estate described here is an Ernesta Labs synthesis, not their convergent implementation.Read
- 23Arc IVMonitoring agents without reading their mindsChain-of-thought is not a supervision surface - it is the agent's own story about its own behavior, and degraded agents tell fluent stories. A paper on monitoring web agents shows what you can see from the outside: repeated actions, loops, tool failures, stale commitments, and no verified progress.Read
Arc V — Learning Without Fooling Yourself
- 24Arc VCHIME: outcomes do not tell you what caused themCHIME uses separate planning and execution memory banks and attributes an outcome to plan, execution, both, or neither before updating memory. Ernesta Labs separately extends that scheme for commercial operations.Read
- 25Arc VDRACO: distributing credit across long trajectoriesAn agent that succeeds on a 200-step trajectory learned something - but from which steps? DRACO uses trajectory-specific rubrics and a judge that cites the steps it used, so credit lands on evidence instead of vibes.Read
- 26Arc VRecuris: validation-gated Skill Memory evolutionRecuris pairs a frozen agent with Skill Memory, localizes failures from structured traces, patches one memory component, and uses paired held-out evidence to accept or reject the revision.Read
- 27Arc VLLM-as-a-judge is not an oracleA paper about production agent-evaluation failures argues the case most teams learn the hard way: an LLM evaluator is an advisory signal, never a promotion authority.Read
- 28Arc VBook-to-skill: compiling human knowledge into agent capabilityA small GitHub repository that does something quietly radical: treats a human-written book as a source that compiles into a small, compact agent skill - extraction first, structure second, compact artifact third, lazy supporting files behind it.Read
- 29Arc VCase note: from a sales playbook to candidate skillsThis first-party case note describes a proposed internal conversion of a client playbook into staged and lazy-loaded modules. No public artifact currently establishes implementation, sample size, cost change, stage-discipline change, or commercial lift.Read
- 30Arc VSkills are behavioral policy: the SkillShift problemA skill can pass every functional test while quietly shifting what your agent decides. SkillShift names the gap between 'works correctly' and 'decides correctly' - and it invalidates the way most teams promote skills.Read
- 31Arc VWhen 100 agents learned to cheatA DeepMind case study on autonomous research swarms shows exploits spreading through shared knowledge faster than audits can catch them - and what a permission model for shared experience has to look like as a result.Read
Arc VI — Multi-Agent / Fleet Safety
- 32Arc VISafety does not compose across reset monitor windowsThe paper's failure is reset safety-monitor state: evidence split across iterations disappears when each window starts fresh. LoopHarness keeps external, non-decaying safety state. Geometric risk decay is explicitly insufficient.Read
- 33Arc VIThe irreversibility budget: cumulative residual risk across a fleetThe paper treats irreversibility as a cumulative residual value-at-risk account maintained by a trusted runtime for each principal across agents, workflows, and tenants. Correct pricing is the central unresolved problem.Read
- 34Arc VIExperience quarantine: how to stop a bad idea spreading faster than you can audit itEvery fleet eventually lets agents share what they learn. The question with a career of consequences attached is how a lesson moves from one agent's discovery to fleet-wide reuse. This Ernesta Labs synthesis proposes a quarantine lifecycle with seven states, because success, trust, shareability, authority and production promotion are five different claims.Read
Arc VII — What We Would Build Today
- 35Arc VIIWhat we would build today: a minimal runtime for long-horizon agentsAn Ernesta Labs synthesis of version-pinned primary sources: five components, explicit trust boundaries, and a clear separation between documented source results, our design recommendation, and unaudited NIKO claims.Read
- 36Arc VIIHow to falsify an autonomous agentMost agent evaluation answers the question 'can it succeed?'. The question that matters is 'what observation would prove it cannot?'. This is the falsification playbook: terminal hypotheses, bounded transaction evals, incident-derived regression, counterfactuals, independent verification, adversarial passes, holdouts, canaries, and the real-world outcome clock.Read
- 37Arc VIIThe builder's checklist for long-horizon agentsNot a recap - a floor. Nineteen areas a long-horizon agent system must answer for, each with the question to ask, the failure mode it guards against, the minimum control, the advanced control, and a test you can run. The most bookmarkable page in this library, by design.Read
Arc VIII — Operational Feedback and Commercial State
- 38Arc VIIIAgent fleets need a coordinator and dense feedbackGitHub's Copilot runtime migration and Z.ai's inference-infrastructure report expose the same production constraint: parallel agents only help when mutation is isolated, scarce resources are leased, and feedback can reject a local hypothesis cheaply before an end-to-end run.Read
- 39Arc VIIIReplay is not reality: three boundaries for learning agentsDream-RSI reuses recorded search trees, Atria Dawn trains from verifiable experience, and Android Bench 2.0 scores partial long-horizon work. Together they show why replay, model progress, and completion diagnostics must remain separate from live success.Read
- 40Arc VIIIA commercial-state architecture for NikoA proposal for making commercial progress explicit, checked against Niko's repository on 17 September 2026, without pretending that opportunity, payment, and commission records already form one verified commercial record.Read
- 41Arc VIIIThe newsletter instructions were attributed to GPT-6 Astra. Then the correction became another failure.An evidence-bounded case study of how a useful community brief became an internal status report, then a correction loop changed policy and explained itself without completing the visible repair.Read
- 42Arc VIIIHow to test an AI SDR before you trust its dashboardVendor pages document capabilities, not effectiveness in your workflow. Map each claim to its exact source, define evidence at every boundary, and test only with controlled seed accounts before exposing real prospects.Read
- 43Arc VIIIJev for AI agents: a fixture-backed consequence-context teaching probeThe v3 artifact separates authored specifications, local synthetic observations, and a future live matched pair. No live v3 run or household effectiveness result is claimed.Read

Arc IX — Persistent Personal Agents
- 44Arc IXGrok Bot documents a shared computer; one community report questions routine timingxAI's overview documents persistent Bots, one shared cloud computer, learned workflows, schedules, and inter-Bot coordination. A separate community source is only one unconfirmed report of intermittent scheduled-routine failure on one Bot; it provides no coordination incident or staff confirmation.Read
- 45Arc IXOpenAI documents Dots responsibilities, wake paths, memory, and delegationOpenAI's documentation describes responsibilities that continue between conversations, several wake paths, selected context for delegated work, and separate memory stores. OpenAI's system card reports evaluation results under stated test conditions. These are vendor claims, not independent product validation.Read
- 46Arc IXMeta Muse separates its agent runtime from outside-world authorityMeta's safety report describes an isolated Muse runtime, separate credential services, and Sentinel authority over connector actions and network egress. One independent CNET report syndicated by Yahoo Tech observed useful shopping work, a capture blockage, inconsistent checkout state, and manual takeover; it supplies no product-wide reliability rate.Read
Reverse SaaS
Ernesta Labs uses Reverse SaaS to describe its model: Service-as-a-Software delivered through a proposed Forward Deployed Software approach. NIKO is the company's first implementation and Experiment Zero is its public proof boundary. This is Ernesta Labs' definition, not a claim that the words or underlying ideas have no earlier history.
READ THE REVERSE SaaS THESIS →Forward Deployed Software
Ernesta Labs' canonical definition: the software itself becomes the specialist deployed into the customer's business to perform the work.
