Three changes the user wanted in the operation skill, all aimed at
making the LLM agent pause and ask the human instead of silently
choosing defaults or auto-confirming:
1. At task submission, ASK for connection (which one to use) and
app_name. The service has no default for app_name and rejects
implicit queue/memory/cores/num_executors defaults, so the
agent has to surface these to the user anyway — better to do
it deliberately than to call a tool, get 400, and re-ask.
2. Before prepare_submit_job, ASK for the submit parameters
(queue, executor_memory, executor_cores, num_executors,
extra_args). The agent tells the user the server-side defaults
it WOULD use so they can approve or override, instead of
picking on their behalf.
3. Before confirm_submit_job, present a one-screen summary of
exactly what will run (connection, app_name, script, queue,
resources, tracking URL) and wait for the user's explicit
affirmative ('yes', 'confirm', 'go', 'y', even an emoji).
A non-answer or 'wait' / 'let me think' is NOT consent. The
agent NEVER calls confirm_submit_job without that go-ahead.
Where the changes live in the skill:
* §0 Mindset — added a 4th 'must' about not auto-confirming,
cross-referencing the new §0.1.
* §0.1 Mandatory user confirmations — new sub-section, spells out
the three checkpoints in detail (what to ask, what counts as
consent, what doesn't).
* §2 The canonical happy path — the numbered list now interleaves
CHECKPOINT 1/2/3 lines with the tool calls, so the pauses are
visually unmistakable.
* §8 Common pitfalls — two new rows: 'auto-confirming without
explicit yes' and 'picking defaults on the user's behalf'.
* §9 End-to-end example — the word-count walkthrough now shows
the full ask flow with sample agent / user dialogue at each
checkpoint, ending in 'only NOW may you call confirm_submit_job'.
The example also adds a 'kill_job: ASK THE USER FIRST' note, since
killing a running YARN app is the same class of irreversible action
as confirming a new one.
File: 449 → 557 lines (+108).
No code changes; tests not affected.
