What is orkcore-dataflow?

A reference guide to Orkid’s dataflow graph system, where connected modules process data in a defined order. It covers graph structure, plug connections, nested graphs, caching, particles, and Python bindings.

Use it when working on dataflow modules, plug connections, topological sorting, particle systems, nested graphs, graph caching, or Python graph inspection.

It gives developers a reliable explanation of how data moves through Orkid graphs and how graph execution is represented in code.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00059	$0.02162
Opus 5.5	$0.00024	$0.00865
Sonnet 5.5	$0.00012	$0.00432
Haiku 4.5	$0.00006	$0.00216

Security

Grade A, and why

orkcore-dataflow 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 2mo 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's new (2026-06/07)

Composite modules SubGraphModuleData / LoopModuleData — nested GraphData with promoted boundary plugs, loop carries, index feeds (ork.core/inc/ork/dataflow/subgraph_module.h)
CookGraphDriver — family-neutral hook interface the composite runtime delegates nested cook/bake execution to (ork.core/inc/ork/dataflow/cook_driver.h)
Per-node Merkle cook cache — opt-in via GraphData::_cacheable; modules opt in per class via DgModuleInst::cookComputeHash / cookStore / cookLoad; GraphInst::computeNodeHashes() + cachedCompute()
TypeKeyedVars _impl on GraphData AND GraphInst — per-family runtime storage keyed by type, so families (hypermesh/terrain/particles) coexist on one graph
Bypass (DgModuleData::_bypassed) + select-as-output (GraphData::_output_node) — first-class serialized graph state; bypassed modules splice out via resolveConnectedOutput()
Python introspection dflow.plugSpec() / dflow.moduleClasses() — plug schemas and node registry straight from reflection (ork.core/pyext/pyext_dataflow.cpp)
Generic family-neutral modules Min/Max/Lerp/Pow/Vec4Combine (ork.core/inc/ork/dataflow/basic_modules.h)

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.

orkcore-dataflow is a skill published in the GitHub repository tweakoz/orkid (35 stars, last pushed 2mo ago), licensed MIT. It adds 59 tokens to every session and 2,162 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 2026-09-01.
