Users as Developers

In the age of AI coding tools, the line between "user" and "developer" is disappearing. If you can describe a bug, you can fix it. If you can imagine a feature, you can build it — with an AI assistant that already understands the codebase.

VMark embraces this philosophy. The repo ships with project rules, architecture docs, and conventions pre-loaded for AI coding tools. Clone the repo, open your AI assistant, and start contributing — the AI already knows how VMark works.

Getting Started

1. Clone the repo — AI config is already in place.
2. Install your AI tool — Claude Code, Codex CLI, or Gemini CLI.
3. Open a session — The tool reads AGENTS.md and the rules automatically.
4. Start coding — The AI knows the project conventions, testing requirements, and architecture patterns.

No extra setup needed. Just start asking your AI to help.

2. Five Skills AI Can't Replace — Git, TDD, terminal literacy, English, and taste — the foundations everything else builds on
3. Why Expensive Models Are Cheaper — Per-token price is a vanity metric; per-task cost is what matters

One File, Every Tool

AI coding tools each read their own config file:

Tool	Config file
Claude Code	CLAUDE.md
Codex CLI	AGENTS.md
Gemini CLI	GEMINI.md

Maintaining the same instructions in three places is error-prone. VMark solves this with a single source of truth:

• AGENTS.md — Contains all project rules, conventions, and architecture notes.
• CLAUDE.md — Just one line: @AGENTS.md (a Claude Code directive that inlines the file).
• Codex CLI — Reads AGENTS.md directly.
• Gemini CLI — Uses @AGENTS.md in GEMINI.md to inline the same file.

Update AGENTS.md once, every tool picks up the change.

What is @AGENTS.md?

The @ prefix is a Claude Code directive that inlines another file's content. It's similar to #include in C — the contents of AGENTS.md are inserted into CLAUDE.md at that position. Learn more at agents.md.

Using Codex as a Second Opinion

VMark uses cross-model verification — Claude writes the code, then Codex (a different AI model from OpenAI) audits it independently. This catches blind spots that a single model might miss. For full details and setup instructions, see Cross-Model Verification.

What the AI Knows

When an AI coding tool opens the VMark repo, it automatically receives:

Project Rules (.claude/rules/)

These files are auto-loaded into every Claude Code session. They cover:

Rule	What it enforces
TDD Workflow	Test-first is mandatory; coverage thresholds block the build
Design Tokens	Never hardcode colors — full CSS token reference included
Component Patterns	Popup, toolbar, context menu patterns with code examples
Focus Indicators	Accessibility: keyboard focus must always be visible
Dark Theme	.dark-theme selector rules, token parity requirements
Keyboard Shortcuts	Three-file sync procedure (Rust, TypeScript, docs)
Version Bumps	Five-file update procedure
Codebase Conventions	Store, hook, plugin, test, and import patterns

Custom Skills

Slash commands give the AI specialized capabilities:

Command	What it does
/fix	Fix issues properly — root cause analysis, TDD, no patches
/fix-issue	End-to-end GitHub issue resolver (fetch, branch, fix, audit, PR)
/codex-audit	Full 9-dimension code audit (security, correctness, compliance, ...)
/codex-audit-mini	Fast 5-dimension check for small changes
/codex-verify	Verify fixes from a previous audit
/codex-commit	Smart commit messages from change analysis
/audit-fix	Audit, fix all findings, verify — repeat until clean
/feature-workflow	End-to-end gated workflow with specialized agents
/release-gate	Run full quality gates and produce a report
/merge-prs	Review and merge open PRs sequentially
/bump	Version bump across all 5 files, commit, tag, push

Specialized Agents

For complex tasks, Claude Code can delegate to focused subagents:

Agent	Role
Planner	Researches best practices, brainstorms edge cases, produces modular plans
Implementer	TDD-driven implementation with preflight investigation
Auditor	Reviews diffs for correctness and rule violations
Test Runner	Runs gates, coordinates E2E testing via Tauri MCP
Verifier	Final checklist before release

Private Overrides

Not everything belongs in the shared config. For personal preferences:

File	Shared?	Purpose
AGENTS.md	Yes	Project rules for all AI tools
CLAUDE.md	Yes	Claude Code entry point
.claude/settings.json	Yes	Team-shared permissions
CLAUDE.local.md	No	Your personal instructions (gitignored)
.claude/settings.local.json	No	Your personal settings (gitignored)

Create CLAUDE.local.md in the project root for instructions that only apply to you — preferred language, workflow habits, tool preferences.
