What is new-arnold-pipeline?

A process for creating a new Arnold native-first pipeline package from a template.

Use it when starting a new Arnold pipeline package.

It gives package creation a defined starting process instead of requiring each package to be set up from scratch.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add peteromallet/Arnold --skill new-arnold-pipeline

Clone the repo

git clone --depth 1 https://github.com/peteromallet/Arnold

Made for: Claude Code, Codex.

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	$0.00021	$0.00398
Opus 5.5	$0.00008	$0.00159
Sonnet 5.5	$0.00004	$0.00080
Haiku 4.5	$0.00002	$0.00040

Security

Grade A, and why

new-arnold-pipeline 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.

What it actually says

Skill: Create a New Arnold Native-First Pipeline

Copy arnold_pipelines/_template/ to arnold_pipelines/<your_pipeline>/.
Edit __init__.py: set name, description, capabilities, keep driver=("native", "project+validate") and supported_modes=("native",), and ensure build_pipeline() compiles the native program and returns a projected Pipeline with a non-null native_program.
Edit pipelines.py: replace the skeleton @phase functions with real logic. Use @pipeline, @phase, @decision, parallel, compile_pipeline, and project_graph from the public arnold.pipeline authoring surface.
Run arnold pipelines check <your_pipeline> to validate the package against the native-first authoring contract (metadata, driver, native program, and graph projection).
Add tests that compile the native program, project the graph, and assert the returned Pipeline carries a non-null native_program.

Dispatch Substrate Note

The native_program compiled by build_pipeline() is a dispatch substrate — it describes how the runtime executes the pipeline, but it does not define the final visible compositional semantics. Panel synthesis, join delegation, parallel merge strategy, subpipeline ownership, and Capsule projection are deferred to later Megaplan layers.

Do not add _legacy.py, graph fallback builders, compatibility namespaces, shim packages, or temporary wrapper modules. The template and this workflow are native-first only. Generated manifests and catalogs are outputs of the authoring path, not editable source.

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.
