Not Just Vibe Coding

August 8, 2025

“Describe what you want, let the AI write it.”

That’s vibe coding in a sentence. It’s fast, creative, and addictive. But without system context, vibe coding becomes roulette: sometimes you ship magic; sometimes you ship maintenance debt.

BrewHQ fixes that—by feeding your AI the right context at the right time, then scaffolding the work into a clean, verifiable implementation plan your agents can execute without breaking the rest of your system.

The Real Problem With Vibe Coding (It’s Not AI—It’s Context)

Vibe coding fails for the same reasons human handoffs fail:

  • Hidden dependencies: a “small” change touches logging, auth, analytics, and a cron job you forgot existed.

  • Shallow requirements: a one-line prompt overlooks edge cases, non-functional constraints, and integration contracts.

  • Untracked decisions: agents (and humans) make micro-choices that aren’t captured anywhere, so rework repeats.

  • Drift across teams/tools: PM notes in Docs, code in Git, tests in somewhere else—AI can’t reconcile the mess.

Vibe coding shines only when the AI has a dependable picture of: what to build, where to change, what it could break, and how to test it.

What BrewHQ Adds (In Plain English)

BrewHQ sits between your idea and your AI coder. It turns “vibes” into implementation-grade context your agents understand.

  • Impact Analysis: Maps requirement → modules → functions → data → external services.

  • AI-Ready Implementation Plan: Structured, stepwise plan with explicit diffs, interfaces, and risks.

  • Guardrails & Tests: Auto-suggested test cases and checks derived from the impact graph.

  • Traceability: Every prompt, change, and rationale is versioned and linkable to commits/PRs.

Failure Modes vs. BrewHQ Guardrails

Common Failure What Happens Without Context How BrewHQ Prevents It
Silent dependency break Passing unit tests, failing at runtime due to upstream contract Impact graph highlights upstream/downstream contracts; plan includes compatibility steps
Overwriting critical logic Agent “simplifies” logic and nukes edge cases Hotspots flagged; plan instructs “wrap, don’t replace” with compatibility shims
Flaky AI output Inconsistent responses per run Deterministic implementation plan + prompt templates + input constraints
Merge conflicts late Parallel features collide Plan reserves file/function touchpoints and defines sequencing
No shared memory Re-explaining context to each agent Centralized requirement context and reusable prompt bundles

The BrewHQ Workflow (End-to-End)

  1. Capture the Requirement

    • Write it like a human (“Add refund to orders”).

    • BrewHQ expands it with assumptions, constraints, and acceptance criteria.

  2. Run Impact Analysis

    • BrewHQ maps the “blast radius”: code paths, DB entities, configs, feature flags, observability, schedules.

    • You get a diff-of-intent: exactly where change should happen.

  3. Generate the Implementation Plan (for your AI)

    • Step-by-step tasks with file/function anchors, interface updates, migration notes, and rollout strategy.

    • Includes prompt packs your coding agent can ingest directly.

  4. Execute With Your AI Agent

    • Feed the plan to GitHub Copilot / Claude Code / Cursor / Replit, etc.

    • Agent works within the plan’s rails; BrewHQ tracks progress.

From “Vibe” to “Verified”:

Concrete Examples

1) Before/After Prompting

Before (vibes only):
“Add a refund option to the orders page.”

After (BrewHQ plan excerpt):

vbnet
Feature: Refunds for Completed Orders
Scope: Web app (Next.js), Order Service (Node), Payments Provider (Stripe), Audit Log
Change Anchors:
– frontend/pages/orders/[id].tsx -> add <RefundButton />
– services/order/refund.ts -> new function refundOrder(orderId, reason)
– integrations/stripe/client.ts -> call refunds.create
– db/migrations/2025_08_12_add_refund_reason.sqlConstraints:
– Only COMPLETED orders within 30 days
Partial refunds must keep tax/VAT correct
– Idempotent: retry-safe via refund_request_id

Tests (auto-suggested):
– Unit: refundOrder rejects PENDING orders
– Contract: stripe.refunds.create called with correct amount/currency
– Integration: order status transitions COMPLETED -> REFUNDED and audit log entry persists

Rollout:
– Behind feature flag REFUNDS_V1
– Add dashboard metric: refund_rate, refund_failures

Result: The agent now codes with guardrails, not vibes.

2) Ready-to-Paste Agent Prompt (Generated by BrewHQ)

sql
You are coding within a Node/Next.js monorepo. Follow the plan below step-by-step.
Do not change files outside "Change Anchors" without creating wrappers.
Plan Summary:
Implement refundOrder(orderId, reason) with idempotency and 30day limit.
Update UI with <RefundButton /> gated by REFUNDS_V1.
Call Stripe refunds API; persist refund events and audit logs.
Add SQL migration for refund_reason and refunded_at.Acceptance Criteria:
All listed tests must pass.
Maintain backward compatibility with existing Order schema.
Add monitoring hooks per plan.

Provide each PR with:
Rationale for any deviation from the plan
Affected files list
Test evidence

What Teams Get (Measurable Outcomes)

  • Fewer regressions: Breakage caught in the impact phase, not after deploy.

  • Higher AI hit-rate: Agents ship correct changes on the first pass more often.

  • Faster reviews: PRs reference the plan; reviewers check intent vs. implementation, not guesswork.

  • Lower onboarding time: New devs + agents inherit context from BrewHQ; less tribal knowledge.

  • Better governance: Every decision is traceable (who prompted what, why, and where it landed).

How BrewHQ Fits Your Stack

  • Works with your repos: GitHub/GitLab/Bitbucket.

  • Any AI agent: Copilot, Claude Code, Cursor, Replit, CodeWhisperer.

  • Your data layer: SQL/NoSQL mappings pulled into the impact graph.

  • CICD: Exposes plan artifacts to pipelines for checks and policy gates.

  • Security: Principle of least privilege; PII-aware scanning during impact analysis.

“But We Already Use Prompt Templates.” Good—BrewHQ Makes Them Useful.

Prompt templates help with style; BrewHQ supplies substance: the call graph, contracts, invariants, and tests that let AI act like a teammate instead of a clever autocomplete. Use your templates—just feed them BrewHQ’s implementation plan and impact context.

Team Playbooks You Can Start With

  • Greenfield feature: Sketch → Impact → Plan → Agent → Tests → Flagged rollout.

  • Refactor risk area: Impact hotspot map → Plan mandates wrappers and compatibility → Agent → Perf tests.

  • Bug + regression: Repro steps → Impact to identify adjacent code → Plan includes contract tests → Hotfix with telemetry.

FAQ (for Skeptical Engineers)

Q: Will agents still hallucinate?
Less. They operate within specific files, interfaces, and tests. If they deviate, Brew’s reviews flag it immediately.

Q: Can we bypass BrewHQ for trivial tasks?
Sure. But anything touching shared codepaths or data deserves an impact pass and a plan.

Q: Isn’t this more process?
It’s front-loaded clarity that saves mid-sprint chaos. Most teams see fewer cycles per ticket.

TL;DR

Vibe coding is powerful—but only with context. BrewHQ gives your AI the system map, the stepwise plan, and the tests to keep speed without sacrificing stability. The result: fewer surprises, cleaner merges, faster delivery.
