hugegraph-regression-tester

hugegraph-regression-tester is a skill for Codex from apache/hugegraph-ai. It costs 54 tokens per session (706 once invoked), scanned A, original, Apache-2.0.

A regression-testing guide for HugeGraph and its MCP tools. Regression testing checks that existing behavior still works after changes.

In plain words
What is it for?
Use it to test graph status and schema inspection, read-only queries, Gremlin generation, extraction, import previews, and tool safety behavior.
Why use it?
It provides repeatable checks for graph queries, schema operations, data extraction, import previews, safety rules, and disabled write paths.

About the project

hugegraph-ai connects the HugeGraph graph platform with artificial intelligence tools, including large language models, graph retrieval, knowledge-graph construction, and graph machine learning. It is intended for developers building applications that query, analyze, or reason over graph data through Python interfaces and related modules.

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-regression-tester 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.

Tool Routes

Test goal Tool
MCP, graph status, or schema inspect_graph_tool(include_raw_schema=false) and when needed inspect_graph_tool(include_raw_schema=true)
Structured read query_graph_data_tool (bounded page or exact ID query)
Natural-language Gremlin generation generate_gremlin_tool(query, execute=false)
Generate Gremlin without execution generate_gremlin_tool(query, execute=false); raw execution must return FEATURE_DISABLED
Raw Gremlin disabled boundary execute_gremlin_read_tool(unsafe_write_query); rejection verifies unconditional disablement, not write classification
Text-to-graph extraction extract_graph_data_tool(text, graph_schema?, example_prompt?)
Import dry-run import_graph_data_tool(mode="ingest", graph_data, dry_run=true)
Import preview boundary Assert confirmable=false, preview_only=true, no plan_id; confirmation returns FEATURE_DISABLED
Verify existing graph data query_graph_data_tool
Schema design design_schema_tool(operations?)
Schema validation apply_schema_tool(mode="validate", operations)
Schema dry-run apply_schema_tool(mode="dry_run", operations)
Raw write Gremlin disabled boundary execute_gremlin_write_tool(gremlin_query); must remain disabled even in admin mode
Admin gate check without a write refresh_vid_embeddings_tool(confirm=false) in separate admin-disabled and admin-enabled processes

Order

inspect -> generate/read -> extract -> import dry-run -> assert preview-only boundary
-> verify read -> schema validate/dry-run -> safety/gate checks

Structured query and plan lifecycle tools require the default core toolset. For a legacy deployment, enable HUGEGRAPH_MCP_TOOLSET=core and restart before using them.

With HUGEGRAPH_MCP_READONLY=false, the admin-disabled refresh call must return FEATURE_DISABLED with details requiring HUGEGRAPH_MCP_ADMIN_MODE=true; the admin-enabled call must return CONFIRM_REQUIRED. Keep confirm=false in both processes to avoid a refresh. Restart between configuration changes. These calls do not verify AI-side authentication or target validation. Validate the write classifier independently with unit tests; raw Gremlin rejection cannot exercise it. For the refresh contract, run the API/MCP regression tests covering default GraphSpace equivalence, required fields and write/auth gates on POST /v1/vid-embeddings/refresh, configuration locking, and mixed-version routing. The capability GET is only discovery; MCP must never fall back to the legacy POST when the versioned route is unavailable. This does not verify physical-instance identity or establish a live rolling-deployment test. Generation and extraction require HUGEGRAPH_MCP_ALLOW_AI=true and a configured AI service. These skills describe current source; published 1.7.1 uses v2_core / v1.

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.

hugegraph-regression-tester is a skill published in the GitHub repository apache/hugegraph-ai (144 stars, last pushed 3d ago), licensed Apache-2.0. It adds 54 tokens to every session and 706 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-27.
