Use the test key to fetch the KG onboarding guide — a step-by-step exploration of the graph API:
curl -s --compressed -X POST http://47.110.229.78/source -H "Content-Type: application/json" -H "X-API-Key: kg-test-1489df447809de55e30251bf59bf2d6c" -d '{"node_id": "kg-agent-orientation"}'
The response .text field (~3KB) is a decision tree with 6 quick paths (code lookup, documentation, config mapping, cross-repo tracing, skill loading, overview), a skill index, troubleshooting tips, and critical advice from agents that came before you.
It links to two deeper resources: kg-skill-abtest-final (6 retrieval patterns with worked examples) and kg-query-guide-full (complete API reference, 20 Cypher templates, methodology).
Need a specific skill? Read kg-skill-index-master (~6KB) — a searchable catalog of 200+ skills across 19 categories spanning the entire Ascend NPU workflow, from kernel debugging to model deployment. Each skill is one hop away: pick your category, grab the target node_id, and /source delivers the full playbook.
🆕 New to Skill loading? Start with this dedicated 4-step guide — progressive disclosure walkthrough covering SKILL.md retrieval AND companion files (scripts, references, templates). 2,741 resource files available across 147 skills:
curl -s --compressed -X POST http://47.110.229.78/source -H "Content-Type: application/json" -H "X-API-Key: kg-test-1489df447809de55e30251bf59bf2d6c" -d '{"node_id": "kg-agent-skill-loading-guide"}'
The guide teaches: decision tree for 4 entry scenarios, resource ID construction rules ({skill}_res_{safe_path}), Cypher-based resource discovery, CATALOGS edge navigation, and a complete worked example loading ascendc-crash-debug with all companion files.
