qwery-core: Instructions file for Codex

AGENTS.md

qwery-core AGENTS.md is an instructions file for Codex, OpenCode from Guepard-Corp/qwery-core. It costs 1,904 tokens per session, scanned A, original, MIT.

Contributor rules for qwery-agent, an AI data-analysis application with a text-based interface. They define privacy, tool-use, and architectural boundaries, including keeping row-level database data away from the language model.

In plain words
What is it for?
Adding analysis tools, querying data with aggregate results, rendering results locally, and organising code across domain, application, adapter, and extension areas.
Why use it?
They prevent sensitive records from leaving the local application and stop changes from breaking the project’s approved architecture.

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

This is Guepard-Corp/qwery-core's own configuration. It tells Codex and OpenCode how to work on qwery-core 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 qwery-core 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

qwery-core 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 2mo 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 — Strict rules for AI contributors

You are contributing to qwery-agent, an AI data analyst with a TUI. This file is the machine-oriented contract. README.md is for humans.

If you don't read this end-to-end, you will violate an invariant. Decisions live in memory/ADR/decisions.md and memory/ADR/ui-decisions.md. Architecture diagrams live in memory/diagrams/.

1. Non-negotiable invariants

These hold before anything else. Breaking them blocks a PR.

  1. Privacy boundary (ADR #28). The LLM never receives row-level data from any datasource.
    • runQuery accepts aggregate-only SQL, single-row scalar output, validated locally.
    • schema and describeQuery return only column metadata.
    • present renders results locally via Mustache + helpers — only { ok, rowCount } goes upstream.
    • The privacy invariant test (tooling/privacy-check.ts) is enforced in pre-push and CI.
  2. Tool minimalism (ADR-locked). Do not add a tool to the core agent unless it materially improves LLM reasoning. "Convenience" is not a justification.
  3. Hexagonal architecture (ADR #12). domain/ and application/ never import from adapters/ or extensions/. Enforced by dependency-cruiser.
  4. English only. All code, comments, identifiers, commit messages and documentation are in English. Chat with the user can be in other languages; the project file content cannot.
  5. No env vars for LLM config. Providers are configured via /models in the TUI, stored at ~/.qwery/config.json. Never re-introduce env-var fallbacks for provider credentials.
  6. No code without unit tests. Every new module / feature / non-trivial change ships with bun:test coverage in the same turn. A code change without tests is incomplete. Cover happy path + at least one edge case + at least one failure mode. For LLM-dependent code, inject a stream function or use Vercel AI SDK's simulateReadableStream / simulateStreamingMiddleware rather than calling real models.

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.
