AI Agent Toolkits
Full-Stack AI Coding Guardrails & Agent Skill Pack
Stop your AI coding agent from breaking your codebase, hallucinating imports, and refactoring files you didn't ask for.

AI coding assistants like Cursor and Claude Code are superhuman at writing code, but notoriously reckless: they poison server components with "use client", hallucinate non-existent package methods, and trigger destructive unrequested refactors. Full-Stack AI Coding Guardrails & Agent Skill Pack is an enterprise-grade vault of drop-in .cursorrules and SKILL.md guardrails engineered for Next.js, TypeScript, PostgreSQL, and Clean Architecture that force AI agents to adhere to strict TDD and non-destructive boundaries.
An enterprise guardrail suite and multi-client AI agent skill pack (.cursorrules, .mdc, SKILL.md) that locks AI coding assistants into strict architectural rules.
Full-stack software engineers, indie founders, CTOs, and dev agencies using Cursor, Claude Code, Windsurf, or Google Antigravity.
File-targeted MDC glob matching, AST import validation, prompt-time TDD enforcement, and non-destructive schema migration locks.
Eliminates 95% of AI code regression bugs, stops client component leakages, and guarantees test-backed pull requests before completion.
Why this architecture wins
Swipe to compare ↔| Without this skill (Manual & Flawed) | With this skill (Deterministic & Gated) |
|---|---|
| Without this skill ✕ AI assistant accidentally inserts "use client" on a parent layout, exposing database queries and secrets in browser bundles. | With this skill ✓ Next.js App Router MDC rule strictly forbids mixing server mutations with client hooks and verifies boundary delimiters. |
| Without this skill ✕ Coding agent marks a feature ticket "complete" without writing tests, leaving silent regression bugs that break in staging. | With this skill ✓ Strict TDD guardrail halts agent execution and refuses to close tasks until failing and passing unit tests are verified. |
| Without this skill ✕ Agent hallucinates destructive migration commands like DROP TABLE when altering database columns. | With this skill ✓ Database safety locks enforce non-destructive additive migrations with explicit rollback verification steps. |

Questions
Which AI code editors and CLIs does this support?
It supports Cursor (via .cursor/rules/*.mdc), Anthropic Claude Code (via SKILL.md), Google Antigravity, and Windsurf. The rules are written in standard Markdown and MDC format.
Does it slow down Cursor or consume excessive context tokens?
No. Every rule uses precise file glob targeting (e.g. app/**/*.tsx or prisma/**/*.prisma) so Cursor only loads the relevant rule when editing those specific files, conserving your context window.
Can I customize the architectural conventions?
Yes. All rules are fully documented in plain Markdown. You can easily tweak naming conventions, preferred libraries, or folder structures to match your team style guide.
Can my agency use this across multiple client repositories?
Yes. The commercial license allows you to install and use these rules across all client repositories without additional licensing fees.
Is the ₹1,499 price GST inclusive?
Yes. The ₹1,499 price is GST-inclusive with instant UPI QR checkout (PhonePe, Google Pay, Paytm) and automated GST tax invoices for business expense ITC claims.
