What is elysia-admin AGENTS.md?

Project instructions for a full-stack administration app built with Vue 3 and TypeScript on the frontend and Elysia with Bun on the backend. They define module boundaries, coding practices, validation, soft deletion, and database-change rules.

Use them when adding backend or frontend features, changing DTOs or schemas, handling soft-deleted records, or working across shared packages and modules.

They reduce accidental coupling between modules and prevent inconsistent dependency, validation, uniqueness, and migration handling.

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	$0.00807	$0.00807
Opus 5	$0.00404	$0.00404
Sonnet 5	$0.00161	$0.00161
Haiku 4.5	$0.00081	$0.00081

Security

Grade A, and why

elysia-admin AGENTS.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 10d 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.

Elysia Admin — Codex Global Rules

Maintainer: synced with .cursor/rules/general.mdc — edit both when changing global rules. Cursor users: canonical copy is general.mdc; this file avoids duplicating the full tree for token savings.

Full-stack admin: Vue 3 + TypeScript (admin/) + Elysia + Bun (server/). Structure: .ai/AI_STRUCTURE.md.

Dependency Direction (Strict)

admin → server (HTTP only)
modules → core | shared | infrastructure | other modules' exported handle functions
core/shared/infrastructure ✗→ modules
modules ✗→ other modules' @database/schema   (cross-table data via owner exported handle function)
shared ✗→ core/database

Generation Principles

Plan ≤5 lines → list files → minimal code
Patterns: backend → .ai/AI_CODE_EXAMPLES_BACKEND.md; frontend → .ai/AI_CODE_EXAMPLES_FRONTEND.md (section only)
No new deps; no unrelated refactors; ask before schema changes
dto.ts: validated fields need error with Chinese user-facing text (error, not errorMessage)
Soft delete & uniqueness: uniqueness checks account for soft-deleted rows; new unique → partial index WHERE del_flag = false
Form validation both sides: frontend rules + backend dto.ts; handle.ts JSDoc on every export
Rule-file language: English AI docs → new/changed prose in English (this edit only); Chinese OK for product copy / trigger phrases
dict_type: short semantic snake_case (e.g. goods_status); reuse via MCP; skip dict for pure boolean — .ai/AI_HANDOFF_SQL.md

Module Dev Triggers

Prefer .cursor/skills/elysia-module-dev/SKILL.md; AI_MODULE_WORKFLOW.md only if ambiguous
Standard CRUD → AI_MODULE_SCAFFOLD.md + create:module / create:page
Layered rules: server/AGENTS.md (backend), admin/AGENTS.md (frontend)

Handoff SQL: file only — developer runs manually. Git: read-only unless user asks.

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.
