Claude Code says your MCP server “Failed to connect” — it might not even be trying
"Failed to connect" isn't the only status claude mcp list can show. Here's why project-scoped MCP servers sit at Pending approval in a freshly cloned repo, the missing-type gotcha that silently drops remote servers, and how to tell which one you actually have.

Your AI-built app might be leaking your API keys — here's how to actually check
AI coding agents routinely wire third-party API keys straight into client-side code. Here's the real distinction between public and secret keys, how to check what your app actually shipped, and how to fix and rotate what's exposed.

Why files your Replit app writes disappear after you redeploy
Your Replit app writes a file and it works — then you redeploy and it's gone. Here's why every Replit deployment resets its filesystem on publish, and how to move storage somewhere that actually persists.

Your AI coding agent just recommended a package that doesn't exist — here's why that's now a security risk
AI coding agents hallucinate package names about 1 in 5 times — and attackers are registering the exact fake names models keep repeating. Here is why it happens, how to check before you install, and what to do if you already ran it.

Your Base44 app went blank after you changed a field — here's why
Base44 app rendering blank after you add, rename, or retype an entity field? Here's the schema/data mismatch behind it, how to confirm it, and how to fix it without redoing your data model.

Your Claude Code hook isn't firing (or isn't blocking anything) — here's why
You wired up a PreToolUse or PostToolUse hook and it either never runs or runs but doesn't stop anything. Here's the exact-match-vs-regex matcher rule, the exit-code-2-not-1 gotcha, and the other silent failure points — plus how to check each one.

Cursor's agent doesn't know about a file that's clearly in your repo? Here's why
You @-mention a file or ask Cursor about code that's right there in the explorer, and the agent acts like it doesn't exist — or worse, invents a plausible-sounding wrong answer. Here's why the index sees less of your repo than you do, and the one move that always works.

Lovable preview is a blank white screen? Here's how to find the real error
Your Lovable app built fine but the preview is just blank white — no error, nothing. Here's why a React app renders nothing when it crashes on mount, and the one move that surfaces the actual error in under a minute.

Why Claude Code stops following instructions you gave it earlier (it's not being stubborn)
Claude Code was doing exactly what you asked, then 20 minutes later it isn't anymore — and there is no error. Here is the actual mechanism (context compaction) and how to make instructions survive it.

Cursor* ignoring your rules? Here's why (it's probably the .cursorrules migration)
Wrote a Cursor rule and it's just... not applying? Here's how Cursor's rules system actually resolves precedence, and the four most common ways a rule silently fails to load.

The AI Fix Loop: why your coding agent makes bugs worse (and how to break the cycle)
Lovable, Replit, Cursor, Claude Code, Base44 — every AI coding tool falls into the same fix loop. Here's why it happens and the exact steps to break it.

Cursor silently reverted my changes — here's the real fix
Cursor applied your edit, you saw it land, and now it's gone with no undo. Here's the actual race condition behind Cursor's silent reverts and how to stop it.

Base44 built its own AI model (Base1) — what it means for your app
Base44 shipped a proprietary model called Base1 and a new Design Pack canvas. Here's what actually changed under the hood and what to expect the next time you prompt your app.

Base44 stuck on 'Thinking'? Here's how to get unstuck
Base44's agent hanging on 'Thinking' forever isn't random. Here's why it happens, the exact sequence to get unstuck, and how to stop losing credits to it.

How to stop Replit Agent from rewriting code you didn't ask it to touch
Replit Agent changed files you never mentioned? Here's why long autonomous runs cause scope creep, and how to constrain the agent so a small fix stays small.
