The Anti-Patterns

Nineteen acts. One repo. Zero acceptance criteria. Each one is a real pattern we keep seeing — what it is, how it happens, why it’s dangerous, and how a serious team prevents it.

Planning & ownership

Prompt & Pray

Vague prompts, accepted output, hoping the architecture is sane.

Architecture

The 9,000-Line Component

AI keeps adding to one file because nobody stopped to redesign.

Read →

Architecture

The Duct-Tape API

Endpoints added one at a time with no coherent model, naming, or errors.

Read →

Operations

Vibes-Only Migration

Framework, platform, or database swap with no real migration plan.

Read →

Planning & ownership

Screenshot-Driven Product Spec

The picture specifies the layout. Permissions, failures, and state changes are still undecided.

Read →

Planning & ownership

The Context Window Bonfire

A chat thread as the source of truth instead of specs or docs.

Read →

Architecture

The Infinite Patch Spiral

Every fix has a special case for the previous fix. Nobody checks the assumption underneath.

Read →

Review & testing

The Fake Confidence Refactor

AI rewrites working code with great confidence and quietly breaks edges.

Read →

Review & testing

The Rubber-Stamp Stage

The reviewer approves the AI summary. The important behavior never gets examined.

Read →

Review & testing

Coverage Theater

Tests and code wrote each other. They agree. They’re both wrong.

Read →

Operations

The “It Worked Once” Deployment

A successful local run stands in for release checks, observation, and recovery.

Security

Secrets on the Big Screen

Credentials and sensitive data escape through prompts, files, tool output, or shared conversations.

Read →

Security

Slopsquatting Festival

An attacker publishes under an AI-invented package name. A successful install looks like validation.

Security

Strangers With Capabilities

An agent gains a third-party extension before anyone establishes what it can access or execute.

Read →

Operations

The Autopilot With No Pilot

An agent takes irreversible, customer-facing actions on its own — no approval gate, no kill switch.

Read →

Operations

The Cloud Project Junk Drawer

AI jams tables, jobs, and permissions wherever the one-off task can finish.

Read →

Operations

The Uncommitted

The business relies on an automation whose running source and setup nobody else can reliably restore.

Read →

Architecture

The Agent That Should’ve Been a Cron Job

Renting a language model to run a deterministic job a script would do for almost nothing.

Planning & ownership

The Disappearing Apprenticeship

Teams stop building the engineering judgment AI assumes they already have.
