Repository instructions for Apache Texera, a workflow platform with Scala services, the Amber workflow engine, an Angular web interface, and an agent service. The guide maps each major part of the codebase to its directory and build files.

In plain words
What is it for?

Why use it?
It gives agents a quick map of where backend services, shared libraries, frontend code, deployment files, and language tools live.

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

This is apache/texera's own configuration. It tells Codex and OpenCode how to work on texera 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 texera configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is python3.12 -m venv ../venv312 && source ../venv312/bin/activate.

About the project

Apache Texera is an open-source platform for collaborative data science in which people create, run, and refine visual workflows with help from AI agents that follow natural-language instructions. Analysts use it for data analysis locally or in cloud deployments, including processing large datasets. Catalogue add-ons support workflows around the platform.

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

texera 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 1mo 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.

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.
