A connector for handing a validated payload from Runx to an n8n workflow. n8n is a tool for building automated workflows with steps, branches, and notifications.

It can check a handoff before sending, invoke a selected n8n webhook, and verify the resulting event.

It keeps authorization, credentials, duplicate protection, and execution records under Runx while n8n runs the workflow.

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	$0.00040	$0.00750
Opus 5	$0.00020	$0.00375
Sonnet 5	$0.00008	$0.00150
Haiku 4.5	$0.00004	$0.00075

Security

Grade A, and why

n8n-handoff 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

n8n Handoff

Hand off governed runx work to an n8n workflow without turning n8n into the authority holder.

This skill is for the outbound side of the n8n integration story. runx owns the policy decision, credential delivery, execution context, and receipt. n8n owns its workflow webhook, canvas, branching, fan-out, and downstream notifications.

Runners

preflight: validates and normalizes the handoff context without network.
send: validates the context, invokes the selected n8n workflow, and reads the invocation back.

Use preflight for reviews, CI, and local harnesses; it never needs approval. The send runner first calls native control.prepare_handoff, which validates the execution identity and produces the canonical delivery envelope. It then uses the provider boundary for workflow.invoke; that boundary owns the exact approval, credential custody, idempotency, and provider operation. A separate provider read verifies the same event and invocation reference. The binding may be local or hosted and may target self-hosted or cloud n8n; the skill never assumes who holds the credential.

Execution context

execution_context must identify where the handoff came from. Include at least one of:

caller or caller_id
principal or principal_id
workflow, workflow_id, workflow_ref, or source_workflow
upstream_execution_id or upstream_run_id

When present, these fields must match the top-level inputs:

platform
event_id
idempotency_key (bound to event_id)
handoff_scope
handoff_audience

The receiver gets the normalized delivery object, not an independently reassembled copy of these fields. That object carries the business payload, source context, exact handoff scope and audience, and idempotency binding the receiver must validate before starting its workflow.

Edge cases

A compatible n8n binding must resolve the selected webhook_host; absence is an actionable preflight blocker, not permission to fall back to ambient HTTP.
Self-hosted and cloud bindings must both dedupe event_id before branching.
Do not put raw provider credentials into payload or execution_context. Pass credential references or let runx hold the provider secret.
If the workflow slug changes, update handoff_audience to the matching n8n:workflow:<slug> value.
The receiver must dedupe by event_id before branching or sending downstream notifications.
