hs-sql-agent: Instructions file for Codex

AGENTS.md

hs-sql-agent AGENTS.md is an instructions file for Codex, OpenCode from tse-wei-chen/hs-sql-agent. It costs 825 tokens per session, scanned A, original, Apache-2.0.

A repository guide for an SQL agent with an ASP.NET Core backend, a Nuxt frontend, a SQLite database, and a git submodule. A git submodule is a separate repository included inside another one.

In plain words
What is it for?
Running the backend and frontend locally, initializing the submodule, using the SQLite data store, building the frontend, and running unit tests.
Why use it?
It gives agents the layout, setup commands, runtime details, and test commands needed to work on the project.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is tse-wei-chen/hs-sql-agent's own configuration. It tells Codex and OpenCode how to work on hs-sql-agent 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 hs-sql-agent 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

hs-sql-agent 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 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.

AGENTS.md

Repo Structure

  • Backend: ASP.NET Core (net10.0) in backend/src/. Main entrypoint: ToolBox/ToolBox.csproj.
  • Frontend: Nuxt 4 (pnpm) in frontend/. Source dir is app/ (not default app.vue root).
  • Storage: SQLite at runtime in data/hsqlagent.db (mounted via Docker volume).

Commands

Backend

# Run locally
cp backend/src/ToolBox/appsettings.Example.json backend/src/ToolBox/appsettings.json
dotnet run --project backend/src/ToolBox

# Run all tests (requires Docker for Testcontainers)
dotnet test --project backend/src/UnitTest/SqlAgent.Test/SqlAgent.Test.csproj
dotnet test --project backend/src/UnitTest/Admin.Test/Admin.Test.csproj

# Run single test
dotnet test --project backend/src/UnitTest/SqlAgent.Test/SqlAgent.Test.csproj --filter "FullyQualifiedName~SqliteStrategyTests"

Frontend

cd frontend
pnpm install   # uses [email protected] (enforced via packageManager field)
pnpm dev       # http://localhost:3000, proxies /api to :8080
pnpm test      # vitest with happy-dom
pnpm generate  # static build to dist/ (used in Docker)

Docker

cp .env.example .env   # configure HMAC_KEY, JWT_KEY and the three independent protection keys
docker compose up -d

Frontend is pre-built and served as static files from ToolBox.dll's wwwroot/.

Gotchas

  • Solution file: backend/hs-sql-agent.slnx (slnx format, not classic .sln). Backend uses central package management via Directory.Packages.props.
  • Frontend aliases: @ and ~ both resolve to frontend/app/ (see vitest.config.ts).
  • Testcontainers tests: SqlAgent.Test spins up real DB containers (Sqlite, Postgres, MySql, SqlServer, Oracle, Firebird). Docker must be running.
  • Nuxt config: ssr: false, dev proxy /api/** → http://localhost:8080/api/**.
  • Env vars: Backend reads from both appsettings.json and environment variables (Docker Compose overrides).
  • execute_dml_sql tool signature: Takes string sql from the caller. McpServer server and CancellationToken cancellationToken are injected by the MCP framework automatically (not caller-provided).

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.
