What is Blacknode AGENTS.md?

Repository instructions for Blacknode, a system for building and running visual workflow graphs. They explain where the main code, editor, runtime, templates, and tests live.

Use them when creating or validating workflows, changing the editor or runtime, adding reusable nodes, modifying the MCP API, or working on extension packages.

They help coding agents choose the correct workflow or development process and follow the repository's change rules.

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	$0.01885	$0.01885
Opus 5.5	$0.00754	$0.00754
Sonnet 5.5	$0.00377	$0.00377
Haiku 4.5	$0.00188	$0.00188

Security

Grade A, and why

Blacknode 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 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.

Blacknode Agent Instructions

These instructions apply to the Blacknode core repository. Extension packages under packages/ are separate Git repositories and carry their own AGENTS.md.

Route the task

Use .agents/skills/blacknode-workflow/SKILL.md when the requested result is a workflow graph, template, editor run, replay, validation, or export.
Use .agents/skills/blacknode-development/SKILL.md when changing Blacknode, adding a reusable node, modifying the editor/runtime/MCP API, or creating an extension package.
When a workflow exposes a missing reusable capability, switch to the development skill, implement and test it, then return to the workflow skill to integrate and validate the graph.

Repository map

Area	Responsibility
`python/blacknode/`	Python graph model, runtime, nodes, CLI, packages, exporters, and MCP
`editor-server/`	FastAPI editor backend, runtime services, sessions, and run replay
`editor/`	React/TypeScript visual editor
`crates/`	Rust types, core, runtime, Python bindings, and CLI
`templates/`	Tracked reusable workflow graphs
`tests/`	Core Python and integration tests
`packages/`	Independently versioned extension-package checkouts

Change rules

Inspect the live node schema or the node decorator contract before adding or connecting ports. Do not invent port names or persisted runtime fields.
Keep core broadly useful. Put hardware stacks, large optional dependencies, and domain-specific integrations in extension packages.
Preserve compatibility for saved workflow node names unless a migration is included. New workflows should use the current generic names.
Keep templates portable: declare kind, schema_version, an explicit entrypoint, complete port metadata, and any metadata.required_packages.
Never commit API keys, run logs, local workflows, editor state, caches, robot calibration data, or generated scratch exports.
Treat camera, CUDA, ROS, and robot streams as managed services. Do not turn a one-shot cook into a polling loop.
Keep physical motion disarmed by default. Retain stale-data, joint-limit, and shutdown safeguards in every transport path.

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.
