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

About the project

IoTDB is a database designed to collect, store, and analyze time-series data produced by connected devices. Industrial IoT systems use it when they need to handle large volumes of device measurements, fast reads and writes, and complex analysis. Catalogue add-ons support workflows for operating or integrating with IoTDB.

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

iotdb 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 14d 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.

Origin

This is a copy

100% identical to skills AGENTS.md — 237 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Project Overview

Apache IoTDB is a time series database for IoT data. It uses a distributed architecture with ConfigNodes (metadata/coordination) and DataNodes (storage/query). Data is stored in TsFile columnar format (separate repo: https://github.com/apache/tsfile). Current version is 2.0.11-SNAPSHOT.

Branch Relationship and Backports

  • master is the primary development branch for the 2.x line. dev/1.3 maintains the 1.3.x line. They have diverged in supported features, implementation, APIs, and dependencies (including TsFile); dev/1.3 is not a mirror of master.
  • A request to cherry-pick (CP) a master PR to dev/1.3 authorizes only that PR's changes and the minimum compatibility adaptations needed to preserve their logic on the target branch. The backport must be logically and behaviorally equivalent to the original PR. Do not make additional changes or use the backport as an opportunity to improve the surrounding code.

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.
