Notes on getting work done by agents
Comparisons, prices as of this month, and what actually works when you hand a task to an AI agent. Written by the people who build and test them.
AI Agent Log Aggregation Patterns: Schemas, Sampling, Redaction
Agent logs grow fast. A single run easily writes dozens of structured events: orchestrator steps, model calls with input and output bodies, tool calls with payloads, retrieval queries with chunk text. Multiply by…
AI Agent Canary Releases: Percentage Rollout for Prompts and Models
The point of a canary is to learn things evals cannot. Evals run on a held-out set; production runs on whatever showed up today. Some regressions are visible only at production scale, on production traffic shapes,…
AI Agents for Fleet Logistics: Automate Dispatch and Routing
Fuel accounts for roughly 24 percent of total fleet operating costs, according to the American Trucking Associations (ATA, 2024). That's the single largest controllable expense for most carriers. And yet the average…
AI Agents for Construction Firms: Bids, Safety, Tracking
Construction is a $1.36 trillion industry in the United States alone (U.S. Census Bureau, 2025). Yet it remains one of the least digitized sectors on the planet. Projects run over budget 80% of the time. Rework eats…
AI Agent Vendor Evaluation: A Scoring Framework
Picking the wrong AI agent vendor costs more than the subscription fee. Across The Standish Group's CHAOS research, software projects have never had a majority success rate: recent CHAOS data puts roughly 31% of…
AI Agent Success Metrics: 12 KPIs to Track and How to Measure Them
Most teams deploy AI agents and then track nothing. Or they track one metric, usually accuracy, and call it done. That approach misses most of the picture. Gartner predicts over 40% of agentic AI projects will be…
AI Agent Secret Management: Store Keys and Tokens Safely
An AI agent that calls five APIs holds five sets of credentials that an attacker can steal. That's not a hypothetical risk. The 2024 IBM Cost of a Data Breach Report found that stolen or compromised credentials…
AI Agent Performance Tuning: Cut Latency and Token Waste
Your AI agent works. It answers questions, calls tools, returns useful output. But it takes eight seconds to respond, and your token bill keeps climbing. Sound familiar? Performance tuning is the difference between…
AI Agent Cost Attribution: Track Spend by Agent, Task, and Team
Your company runs 15 agents across four departments. The LLM bill arrives as a single line item. Finance asks: "Who spent what?" You don't have an answer. That gap between aggregate spend and per-team accountability…
The AI Agent Security Checklist for 2026: 47 Controls Every Team Should Verify
Prompt injection is the #1 risk on the OWASP LLM Top 10 (OWASP, 2025). Agents amplify every LLM risk by adding tools, persistence, and autonomy. This checklist gives you 47 controls across 10 categories. Each control…
AI Agent Handoff Patterns: 8 Contracts That Don't Drop Work
A handoff is the contract between two agents (or one agent and a human) that specifies what gets passed, when, and what happens if the receiver is unavailable. Eight patterns cover most production cases. LangGraph,…
AI Agent Fallback and Retry: A 2026 Playbook for Idempotency, Backoff, and Model Cascades
Naive retries amplify outages; smart retries absorb them. The Google SRE book defines a retry budget so retries can't exceed a fixed fraction of normal load (Google SRE, ch. 22). For AI agents the same logic applies…
Where to Publish AI Agents in 2026: Builder's Guide
You can build an AI agent in a weekend. Finding people who will pay to run it is the hard part. Most builders default to GitHub, get a few stars, and call it shipped. Three months later, the repo is collecting dust…
What Makes a Top AI Agent on Gravity (2026)
Builders ask the same question on day one: "How do I get my agent to the top of Gravity?" The honest answer is that we do not sell that spot. Not to the loudest builder, not to the highest bidder, not to ourselves.…
How to Validate an AI Agent Idea Before You Build
Most builders skip validation. They pick an agent idea on Saturday, build for 40 hours over two weekends, publish to a marketplace, and watch it sit at zero runs. According to CB Insights' 2024 post-mortem analysis…
From n8n Hobbyist to AI Agent Income: 2026 Guide
n8n's community crossed 200,000 builders in 2024 according to n8n's own docs and community stats, and the GitHub star count sits north of 60,000. That's a small city of people who know how to chain APIs together. Yet…
How to Monetize AI Agents in 2026: Builder Guide
If you can build an AI agent in n8n, LangChain, make.com, or any of the other workflow tools that have eaten the last three years, you can earn from it. The path from a working workflow to actual recurring revenue is…
First 5 AI Agents to Build for Recurring Income (2026)
Most first-time AI agent builders pick the wrong agent. They chase a clever idea instead of a boring, repeatable workflow that someone already pays a human to do. The five agents below all hit the same pattern: clear…
AI Agents for Veterinarians: 9 Use Cases That Replace a Missing Front-Desk Hire (2026)
Veterinary practices are losing front-desk staff faster than they can hire. The Merck Animal Health Veterinary Wellbeing Study and AVMA workforce reports both frame the shortage as structural rather than cyclical…
AI Agents for Restaurants: 10 Daily Ops Jobs to Automate (2026 Guide for Independents and Small Chains)
Restaurants typically run on a pre-tax margin of roughly 5 percent (National Restaurant Association, 2026) and food-away-from-home prices rose 4.1 percent year over year per USDA Food Price Outlook, 2026. A GM at an…
AI Agents for Every Profession: 2026 Index of 55+ Jobs
The short answer. Almost every profession can use an AI agent today, and the best results come from agents tuned to one job rather than tools that try to be everything. Gravity indexes expert-built agents across 55+…
AI Agents for Dental Practices: 8 Workflows That Pay for Themselves in 90 Days (2026)
Dental practices lose revenue in predictable places: 10 to 15 percent of scheduled visits to no-shows, recall lapse over 30 percent, treatment plans diagnosed but never scheduled, insurance verifications that consume…
AI Agent Unit Economics for Builders (2026)
Builders keep asking the same question: is this agent actually worth shipping? Most answers floating around treat AI agents like SaaS products with seat counts and CACs. They are not. An agent is a piece of software…
AI Agent Marketplace Splits Compared (2026)
Most builders look at a marketplace headline split, 70/30, 80/20, 95/5, and stop reading. That's the expensive mistake. The percentage is the smallest variable in the equation. What matters is everything sitting…
AI Agent Marketplace: The Complete 2026 Guide
Most teams don't need another tool to build an AI agent. They need an agent that already works. According to McKinsey's State of AI 2025 survey, 88% of organizations now report regularly using AI in at least one…
Best Open-Source AI Agent Frameworks in 2026
Open-source agent frameworks are not a competitor category to managed platforms. They are a different layer of the stack: libraries you build with, not products you buy. The choice between them comes down to…
Enterprise AI Agent Platforms in 2026 (Buyer Guide)
Enterprise AI agent buying is a different category from founder buying. The shortlist is shorter, the requirements are heavier, and the procurement timeline is measured in quarters. The platforms that win enterprise…
Cheapest AI Agent Platforms in 2026: Free to $20/Month
"Cheapest AI agent platform" is the wrong question if you stop at the marketing page. The real cost includes LLM tokens, infrastructure, integrations, and time spent on glue code. A platform that looks free can be…
Bootstrapped-Friendly AI Agent Tools in 2026
Bootstrapped founders read pricing pages differently. The question is not "what is the best agent platform" but "what is the cheapest agent platform that does not break when I scale to ten agents." The platforms that…
Best Personal AI Agents in 2026: 9 Compared for Personal Use
The phrase "personal AI agent" is a moving target. In 2024 it meant a chatbot. In 2026 it means an agent that runs for one person, on their behalf, against their actual apps and data, often without supervision. The…
