Splice
When a run pauses — at an approval gate or a tripwire set to park — the dock doesn’t just ask yes or no. It hands you the text in an editable box.
Editing it before continuing is a splice: downstream nodes receive your version, not the original.
Why it matters
Section titled “Why it matters”Most of the time a human reviewing an intermediate result doesn’t want to veto it. They want to fix two words, delete a wrong paragraph, or add the constraint the agent forgot — then let the pipeline continue.
Without splice you’d reject, edit the prompt, and re-run the whole branch. With it you fix the value in flight.
How it works
Section titled “How it works”- The run parks; the node shows as waiting.
- The dock shows the inbound text, editable.
- Approve · continue forwards the current contents of the box.
- Reject · stop aborts the run.
Leave the text untouched and approve, and it’s a plain approval gate.
Where it appears
Section titled “Where it appears”| Source | Behavior |
|---|---|
| ✓ Approval node | Always parks for review |
| ‡ Tripwire, action = park | Parks only when the condition fires |
| ⇄ Live handoff | Chat with an agent until Ready, then the distilled result continues the run |
Detached runs
Section titled “Detached runs”There is no dock in a headless run. Pass --approve-all and parked text is forwarded unchanged, with a log line recording that it was auto-passed. Without the flag, a workflow containing gates refuses to start rather than silently skipping a checkpoint you meant to keep.
‡ tripwire park auto-passed (approveAll) — content 43 chars < min 200Patterns
Section titled “Patterns”Edit the brief, not the prompt. Put an approval right after a distill step: correct the summary once, and every downstream agent inherits the correction.
Trim before it spreads. An iterator fed by a parked gate lets you delete the three junk items before they each become an agent run.
Guard the expensive step. Park before implement, not after — the cheapest edit is the one made before the tokens are spent.
Examples
Section titled “Examples”▶ Splice gate — approval with an editable splice, no agent required. ▶ Min-chars tripwire — a park triggered automatically by a short draft.
