DAF Intent Guard — 意图漂移检测

Tracks intent drift across multi-turn tasks. Before executing any multi-step task, call this to detect if the user's new instruction is a small patch, requires replanning from a checkpoint, or should abort the current task entirely. Returns patch/replan/abort decision with semantic distance and anchor rollback count.

DAF Intent Guard

Use this skill when:

• A user modifies an in-progress task
• A user gives a new instruction that might conflict with what is already done
• You need to decide whether to continue, roll back, or restart

How to use

Call the guard before executing any new instruction on an ongoing task:

python3 {baseDir}/daf_guard.py \
  --current-anchor <index> \
  --old-constraints '<json>' \
  --new-constraints '<json>' \
  --new-action '<action>' \
  --requires '<json_array>' \
  --anchors '<json>'

Decision meanings

• patch: Small change. Update parameters and continue from current anchor.
• replan: Significant change. Roll back to anchor first_affected_anchor and re-execute from there.
• abort: Task cancelled or too much has changed. Stop and confirm with user before restarting.

Example

User was booking a flight (seat locked at anchor 1), now says "change destination to New York":

• old-constraints: {"destination":"KL","date":"today","cabin":"economy"}
• new-constraints: {"destination":"New York","date":"today","cabin":"economy"}
• Expected: replan (destination change affects anchor 0)
