coding-guardrails

by Skills Hub

Installs behavioral guardrails against classic LLM coding failures and audits the current session against them. Encodes six enforceable rules: verify APIs exist in node_modules or docs before calling them, state assumptions before coding, prefer minimal diffs over rewrites, re-read the actual error text instead of pattern-matching a fix, never claim done without running the code, and express uncertainty numerically. Writes the rules into CLAUDE.md with an idempotent merge and demonstrates each with a before/after example from this repo. Use when you hear: install guardrails, coding guardrails, stop hallucinating APIs, the agent keeps rewriting everything, add LLM safety rules, make Claude more careful, audit this session, why did you claim it works, anti-slop rules, Karpathy-style guidelines, tighten your coding behavior.

unit-testGenerate comprehensive unit tests with edge cases, error paths, and boundary values. Auto-detects test framework (Vitest, Jest, pytest, go test, flutter_test, RSpec, cargo test, JUnit), scans for untested functions by priority, adopts existing test conventions, generates tests with proper mocks, runs them, and self-heals failures in up to 3 iterations. Measures coverage before and after. Use when you need to add unit tests, increase code coverage, test edge cases, or verify error handling paths.18 installsdesign-to-codeTurn a design into production-quality frontend code: extract a design system with tokens and components, make layouts responsive across breakpoints, add dark mode with WCAG-compliant theming, then run a UX audit to validate everything. Use when implementing UI from Figma, adding theming, making an app responsive, or overhauling frontend design consistency.17 installssecurity-reviewSecurity audit and vulnerability assessment for any codebase.

Frequently asked questions about coding-guardrails

What does the coding-guardrails skill do?

Installs behavioral guardrails against classic LLM coding failures and audits the current session against them. Encodes six enforceable rules: verify APIs exist in node_modules or docs before calling them, state assumptions before coding, prefer minimal diffs over rewrites, re-read the actual error text instead of pattern-matching a fix, never claim done without running the code, and express uncertainty numerically. Writes the rules into CLAUDE.md with an idempotent merge and demonstrates each with a before/after example from this repo. Use when you hear: install guardrails, coding guardrails, stop hallucinating APIs, the agent keeps rewriting everything, add LLM safety rules, make Claude more careful, audit this session, why did you claim it works, anti-slop rules, Karpathy-style guidelines, tighten your coding behavior. It's a reusable SKILL.md instruction set that loads into your AI coding assistant on demand, no prompt engineering, no copy-pasting every session.

How do I install the coding-guardrails skill?

Run `npx @skills-hub-ai/cli install coding-guardrails` from your terminal. The CLI writes the SKILL.md to the correct location for your AI tool (e.g. ~/.claude/skills/coding-guardrails/ for Claude Code or ~/.cursor/skills/ for Cursor with --target cursor) and adds it to your project's .skills.json lockfile.

Which AI tools does coding-guardrails work with?

coding-guardrails runs in Claude Code. It follows the open Agent Skills standard (SKILL.md), so the same skill works in every supported tool without modification.

Is the coding-guardrails skill free?

Yes. Every skill on skills-hub.ai is free and open-source. There are no premium tiers, paywalls, or usage limits. You only pay for whatever AI assistant you're already using.

How do I use coding-guardrails after installing it?

In Claude Code, type `/coding-guardrails` (or whatever slash command the skill registers) and the AI follows the skill's instructions immediately. You can also reference it by name in natural language, your AI loads the skill into context when relevant.

Can I share the coding-guardrails skill with my team?

Yes. Commit your project's .skills.json lockfile and teammates run `npx @skills-hub-ai/cli install` (no args) to install every skill at the exact version you pinned. Organization-scoped installs work via skills-hub.ai organizations.
