coding-style

A set of coding standards for the OneContext monorepo, a repository that contains multiple related software packages. It covers architecture, project layout, React and backend patterns, validation, formatting, and product language.

In plain words
What is it for?
Use it when adding or refactoring OneContext frontend, backend, shared-package, project-structure, or copy code.
Why use it?
It helps contributors place code correctly and follow the same design and implementation conventions across the repository.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code, Codex.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

coding-style scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

OneContext Coding Style

Apply these conventions when writing or refactoring code in this monorepo.

Reference Files

File Scope
coding-style.mdc General code quality — commenting, control flow, type derivation, business logic hygiene
frontend.mdc React component patterns, composition, hooks, module organization
backend.mdc Layered architecture, Hono route patterns, Zod validation, API design
project-structure.mdc Monorepo layout, package descriptions, where to place new code

Key Principles

  • Self-documenting code — comment only to explain why, not what
  • Early returns — flatten logic with guard clauses; avoid deep nesting
  • Derive types from source — Prisma → Zod → API → frontend; avoid duplicate definitions
  • Follow project structure — domain-first organization; place code where it belongs
  • Biome for formatting — do not manually format; let the toolchain handle it
  • Prefer Server Components — limit use client to interactive UI concerns
  • UI / visual: Apply brand-guidelines for colors, typography, spacing. Copy / messaging: Apply brand-copy-guidelines for headlines, CTAs, landing copy, docs, social (tone, voice, word choice).
Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
