What is webobsidian CLAUDE.md?

A project-specific instruction file for the WebObsidian application, a self-hosted web app designed to work like Obsidian. It tells Claude Code how to follow the product requirements, implementation plan, task list, and project conventions.

Use it when working on WebObsidian to consult the product requirements, update the implementation plan, synchronize session tasks, and follow the project's TypeScript and documentation rules.

It keeps coding work aligned with the project's approved design and progress records. It also requires changes to be checked before work is marked complete.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00612	$0.00612
Opus 5	$0.00306	$0.00306
Sonnet 5	$0.00122	$0.00122
Haiku 4.5	$0.00061	$0.00061

Security

Grade A, and why

webobsidian 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md — Hướng dẫn làm việc cho Claude Code trên dự án WebObsidian

Bối cảnh

WebObsidian là web app self-hosted clone toàn diện Obsidian. Thiết kế chính thức nằm ở PRD.md. Tiến độ phát triển được track ở IMPLEMENTATION_PLAN.md.

Nguyên tắc bắt buộc (đọc trước mỗi phiên làm việc)

Luôn bám sát PRD.md. Trước khi code một tính năng, đối chiếu với phần FR/NFR/API/data model tương ứng trong PRD. Không tự ý đổi kiến trúc hay phạm vi. Nếu thấy cần lệch khỏi PRD, cập nhật PRD.md trước (ghi rõ lý do, tăng version/changelog) rồi mới code.
Luôn cập nhật IMPLEMENTATION_PLAN.md. Mỗi khi bắt đầu hoặc hoàn thành một mục:
- Đổi checkbox: [ ] → [~] (đang làm) → [x] (xong).
- Cập nhật dòng "Cập nhật lần cuối" và thêm dòng vào "Nhật ký tiến độ" (ngày + tóm tắt).
- Một mục chỉ đánh [x] khi code chạy được/được kiểm chứng, không phải khi mới viết xong.
Đồng bộ với todo list của session. Todo nội bộ phải phản ánh các mục trong plan.
Tài liệu là nguồn sự thật. Khi phạm vi thay đổi theo yêu cầu người dùng: cập nhật PRD.md (thiết kế) và IMPLEMENTATION_PLAN.md (thêm/sửa mục) trong cùng lần thay đổi.

Quy ước kỹ thuật

Ngôn ngữ: TypeScript cho cả server và web. Tránh any khi có thể.
Cấu hình runtime: chỉ dùng file JSON (data/settings.json) — không thêm DB engine.
Bảo mật: không log secret/token/API key; hash trước khi lưu; guard path traversal.
Commit/push git chỉ khi người dùng yêu cầu.

Lệnh hữu ích

npm install            # cài deps toàn workspace
npm run dev            # chạy server + web (dev)
npm run build          # build web rồi server
npm run start          # chạy production (server serve web đã build)
npm run typecheck      # kiểm tra type cả 2 workspace
docker compose up      # chạy full stack

Cấu trúc (xem PRD §2.2)

server/ — Express API (routes, services, middleware, plugins shim).
web/ — React SPA (components, lib, styles).
data/ — runtime config & index (gitignored).
docs/ — tài liệu bổ sung.

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.
