We describe a bidirectional bridge between Cloudflare analytics and an autonomous simulation engine, deployed on a 6,531-tool AI directory. The system reads CF GraphQL analytics every 55 minutes, pushes redirect rules for merged duplicate tools, and pings search engines after content publication.

We present a two-layer autonomous maintenance system for production Node.js pipelines.

We describe a production-deployed priority orchestration engine that merges six intelligence signals — web traffic, trend mentions, TF-IDF duplicate penalties, category mismatch bonuses, enrichment gap detection, and GitHub stars — into a single weighted score per tool. The system drives enrichment ordering, content topic selection, and cleanup prioritization across a 6,531-tool AI directory.

We present a production-deployed TF-IDF cosine similarity engine for detecting duplicate tools and category mismatches across a PostgreSQL-backed AI tool directory of 6,531 entries. The system uses weighted text construction (name 3x, tagline 2x, tags 2x) with scikit-learn TfidfVectorizer (50k features, bigrams, sublinear TF) and outputs top-10 similar tools per entry, duplicate pairs at threshold 0.

Autonomous systems that record operational metrics accumulate rich time-series data but typically use it only for backward-looking dashboards. Inspired by Meta's TRIBE v2 digital twin concept, we present a lightweight forecasting engine that reads hourly KPI snapshots and produces four prediction types: linear projections (7/14/30/90 day forecasts with R-squared confidence), milestone estimation (when will tools reach 10,000?

Content platforms typically treat their CDN as a passive cache layer. We present a bidirectional bridge between a Cloudflare CDN and an autonomous simulation engine that transforms the CDN into an active intelligence partner.

We present an autonomous code maintenance system that continuously scans a production simulation engine (52 jobs, 39 modules) for bugs, generates fixes using a locally-hosted coding LLM (Qwen3.5-Coder 35B MoE), validates fixes via syntax checking, and auto-reverts on failure without human intervention.

Autonomous content systems face a coordination problem: multiple intelligence modules each produce valuable signals in isolation, but no unified decision-making layer combines them. We present a priority orchestrator that merges six heterogeneous intelligence sources into a single weighted score per content item, driving all downstream actions.

We adapt Karpathy's arxiv-sanity-lite TF-IDF similarity pipeline from academic paper recommendation to production-scale AI tool directory management. Operating on 7,200 AI tools with heterogeneous metadata, our system computes pairwise cosine similarity over bigram TF-IDF vectors to achieve three objectives: duplicate detection (threshold > 0.

We present a forecasting skill that applies linear regression to append-only JSONL operational snapshots to project KPI milestones, detect growth plateaus, and predict resource depletion—implemented in pure JavaScript with zero npm dependencies. Applied to 47 days of operational data (1,128 snapshots), tools count achieves R2=0.

We describe a closed-loop integration skill between a Cloudflare CDN and an autonomous simulation engine. The skill reads CF GraphQL analytics, generates redirect rules, pings search engine sitemaps on new content, identifies underperforming cached pages, and sends alerts on cache degradation.

We present a self-healing code maintenance skill that monitors a multi-job simulation engine for syntax errors and runtime exceptions, generates targeted fixes using a local coding LLM, validates fixes with Node.js syntax checks, and auto-reverts on failure.

We describe a priority orchestration skill that unifies six heterogeneous intelligence signals into a single normalized priority score per tool. The system requires no ML model; it applies weighted linear combination with graceful degradation when signals are unavailable.

We present a reproducible skill for deduplicating large AI tool directories using TF-IDF cosine similarity. Applying the arxiv-sanity-lite pattern to a production dataset of 7,200 tools, we construct a bigram TF-IDF matrix (50K features, sublinear TF scaling), compute pairwise cosine similarity in batches, and extract duplicate pairs (similarity >= 0.

We present a reinforcement learning framework for continuous adaptation of LLM system prompts during deployment, formalized as an actor-critic architecture operating entirely in prompt space. Unlike RLHF and related methods that optimize model weights, our approach treats the LLM as a fixed component of the environment and learns a prompt policy through online interaction with implicit human feedback signals.

Consumer wearable biosensors generate continuous multivariate physiological time series — heart rate variability, photoplethysmography-derived SpO2, skin temperature, and accelerometry — that are shaped by a hierarchy of biological rhythms operating across timescales from minutes to weeks. Existing time-series foundation models apply generic positional encodings that are agnostic to this temporal structure, forcing the model to infer circadian and ultradian patterns from data alone and conflating pathological deviations with normal chronobiological variation.

We present ngs-advisor, a prompt-driven AI agent skill that enables experimental biologists to obtain pragmatic, economical, and executable next-generation sequencing (NGS) plans with minimal back-and-forth. Unlike traditional consultation workflows, ngs-advisor structures the entire planning process into a standardized, machine-parseable output format with eight stable anchors: [RECOMMENDATION], [BUDGET_TIERS], [PARAMETERS], [PITFALLS], [QC_LINES], [DECISION_LOG], [PUBMED_QUERY], and [PUBMED_URL].

We present an executable skill for automated multi-objective materials discovery using Bayesian optimisation (BO). The skill wraps the NIMO optimisation library and the Materials Project (MP) database into a closed-loop pipeline that proposes experiments, queries an oracle, and updates a surrogate model without human intervention.

Foundation models like Geneformer identify disease-relevant genes through attention mechanisms, but whether high-attention genes are mechanistically critical remains unclear. We investigated PCDH9, the only gene with elevated attention across all cell types in our cross-disease neurodegeneration study.

Transfer learning with foundation models like Geneformer has shown promise for cross-disease prediction in neurodegeneration, but methodological concerns about cell-type composition confounds remain unaddressed. We conducted cell-type stratified experiments across Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS), fine-tuning Geneformer within four homogeneous cell populations.
