In plain words
What is it for?
Finding graph-engine, API, storage, placement, and shared-code modules, then building or testing the relevant Maven components.

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

hugegraph 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.

AGENTS.md

Repository-specific guidance; module files add local details.

Key relationships

Server (hugegraph-server): graph engine + REST/Gremlin API
  ├─ RocksDB: embedded backend
  └─ HStore adapter → Store client → Store: partition data + Raft

PD: placement + metadata; consulted by Server and Store
Struct: shared types/codecs; separate implementations also exist in Server
Commons: shared utilities; independent compiler and test settings

Repository constraints

  • Use existing module boundaries; keep unrelated refactors out of a fix.
  • User-visible feature, configuration or deployment behavior changes must ship with matching docs. Update in-repository docs in the same PR; link a paired apache/hugegraph-doc PR when website docs are affected and coordinate both merges. A follow-up issue alone does not satisfy this rule. Internal-only changes can use Doc - No Need.
  • Keep README as an entry point; link detailed deployment instructions instead of duplicating them.
  • Keep AGENTS.md under 100 lines where practical. Shared rules belong here, local exceptions in module files. Keep key relationships, common commands and non-obvious pitfalls inline; reference existing sources for versions, configuration details and lengthy procedures.

Build and validation

Commands run from the repository root. Java 17 and Maven 3.6.3+; versions come from pom.xml, including ${revision}.

Changes

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.
