Bootstrap a service you don't understand and you ship a black box.
Vibe-coding a service you have never touched traps you at the first failure. Point the agent at its docs over MCP and force it to teach you back.

Technical insights into multi-agent orchestration, local protocols, and
developer-centric terminal workflows.
An agent runs forever or quits one bug short. You need two brakes.
An unattended agent loop has no instinct for 'done.' Give it an iteration ceiling it can't argue past and a completion sentinel it can raise.
Your smartest worker forgets every job the moment it ships.
Pairing an isolated subagent with the right tools and a slice of your conventions rebuilds the proven agent loop without dragging tool logs into your thread.
A legitimate MCP server with two trust levels is the exploit
The dangerous MCP server isn't the malicious one - it's the convenient all-in-one that reads untrusted data and holds privileged access to a second system.
An agent watching its context fill rushes the ending. Take the wheel.
When the window fills, agents cut corners and auto-compaction throws away the wrong things. Author a handoff file, eyeball it, restart in a session you control.
Stop handing your agent the API key. Give it a phone, three numbers.
An MCP server is a trust boundary, not a passthrough. Hold every secret server-side and expose a curated verb set, so an injected agent is bounded by it.
An Agent Gets Worse Long Before Its Context Window Fills Up
Stop fighting the context limit with a bigger window. Write an exhaustive plan to a file, then relay fresh sessions that each tick off items until it ships.
The best prompt you'll ever write is the one you delete.
An agent that waits for you to remember to ask it is a toy. Wire a deterministic event to a headless run that reads your rules, and routine work fires itself.
Run your whole eval suite on every commit and you'll stop running it.
The fix for slow, flaky agent evals isn't a faster suite - it's two loops. A cheap deterministic gate on every PR, and a slow judge suite on a schedule.
Your agent says the delete worked. The proof is a sentence it wrote.
Give every consequential tool a declared output schema and validate at the boundary, so the UI gates on a real success boolean instead of the agent's prose.
