Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is thapaliyabikendra/ai-artifacts's own configuration. It tells Claude Code how to work on ai-artifacts itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai-artifacts configures →

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

ai-artifacts CLAUDE.md 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 5d 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.

Guidance for Claude Code when working with this repository.

Project Overview

Clinic Management System - A layered monolith built on ABP Framework using Domain Driven Design. Manages patients, appointments, and doctor schedules.

Tech Stack

Component Technology
Runtime .NET 10
Framework ABP Framework 10.0.1
Database PostgreSQL
ORM Entity Framework Core
Auth OpenIddict (OAuth 2.0)
Mapping Mapperly (NOT AutoMapper)
Validation FluentValidation (NOT data annotations)
Testing xUnit + Shouldly + NSubstitute

Git Rules — STRICT MODE

NEVER

  • push --force, reset --hard, clean -fd, or delete branches
  • Commit to main, master, or protected branches
  • Rebase shared branches
  • Commit secrets, .env, or appsettings.*.json with sensitive data

ALWAYS

  • Create feature branch: ai/<description>
  • Check: git status, git diff, verify branch before commit
  • Pull (no rebase) before push
  • Push only feature branches

COMMIT FORMAT

<type>: <what>

Why:
* <reason>

STOP IF

  • On protected branch
  • Git errors/conflicts
  • Unclear state

Safety > Speed. Agent is not the repo owner.

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.
