AGENTS.md vs CLAUDE.md: I Ran Both for Three Weeks (2026)
AGENTS.md vs CLAUDE.md is not a format war. A 2026 field log on running both files in one repo, why Claude Code ignores AGENTS.md, and the one-line import that fixed it.

AGENTS.md vs CLAUDE.md is not a format war. A 2026 field log on running both files in one repo, why Claude Code ignores AGENTS.md, and the one-line import that fixed it.
A working reference: the five MCP servers I keep loaded in Claude Code after a year of daily use, the ones I removed, why every server costs context-window tokens, and the exact scope config that keeps the list short.
A field note on Claude Code plan mode after months of daily use: when it saves me, when I skip it, three failure modes the listicles miss, and the exact habit I built around it.
Six AI coding agents sit in my dock in 2026, but I do not open all six every day. Here is the honest field log of which one I reach for when the task is a refactor, a chore, or a tight edit loop, plus the routing rule that keeps surviving.
Is vibe coding bad? After six weeks of vibe coding a side project, here is where it helped, where it quietly made me worse, and the four guardrails I run now.
A field note on Claude Code commands: which custom slash commands actually earned their place, which I deleted, and the 2026 question the listicles skip, when a command should have been a skill.
A month of running Cursor and Claude Code daily on the same Next.js project. What each one is actually for, where they bit me, the cost difference, and why I kept both instead of picking a winner.
Running three to five AI coding agents at once with git worktrees for two weeks: the exact setup, honest merge and cost numbers, the failure mode nobody warns you about, and when parallel agents are the wrong call.
One weekend, one invoice tracker, three AI app builders (Lovable, Bolt.new, Totalum). Honest field log: where each one shone, where each one stalled, and which one survived to Monday morning.
A 30-day field log of running an MCP server in production: four failure modes the tutorials skip, honest latency and cost numbers, and when an MCP server is the wrong tool.
Seven days of running Cursor background agents on a real Next.js side project. 23 tasks, 14 PRs, 9 merged, $11.40 spent. What shipped, what failed, the task spec that doubled the merge rate, and when to reach for an AI app builder instead.
I take a two-year-old expense-splitter app with a rotting stack and rebuild it from scratch in a single weekend. I scaffold the plumbing fast with an AI app builder, then spend my real hours on the settle-up logic and UX I actually care about. The takeaway: scaffold the boring parts, hand-build the soul, model the data before the UI, and ship the unglamorous last 20% the same weekend.
