Questions#
Q2Multiple choice
What distinguishes 01-simple from 02-intermediate?#
Answer
A — 01-simple is the fully guided, sample-data happy path; 02-intermediate uses the learner's own data with checkpoints instead of click-by-click steps.
Q3Multiple choice
What is the defining feature of 03-advanced?#
Answer
B — 03-advanced presents a real breakage (real incident or CHANGELOG "Fixed" entry) that the learner diagnoses without guided steps.
Q4Multiple choice
Which sequence of calls does examples/chat_app.py use to implement the preferred pattern?#
Answer
B — This is the exact call chain the preferred-pattern reference example uses.
Q5Multiple choice
What does panel() return?#
Answer
B — panel(session, kwargs) -> CocoChatResult.
Q6Multiple choice
In panel(), what does setting output_label=None do?#
Answer
B — output_label=None hides the bordered output container; the default label otherwise is "CoCo output".
Q7Multiple choice
Which panel() parameter switches between showing the running transcript and showing only the latest field-style output?#
Answer
A — output_mode toggles between "transcript" (default) and "field" rendering.
Q8Multiple choice
What does chat_input_bar(session, accept_file=True) enable?#
Answer
B — accept_file=True (or "multiple") turns on file attachment, which is saved via the upload helpers into the session's cwd.
Q9Multiple choice
Which of these is a real copilot_rail() parameter?#
Answer
A — example_questions is a documented copilot_rail() parameter; the other three are not part of its signature.
Q10Multiple choice
What is job= used for in copilot_rail()?#
Answer
B — job= takes a dict (prompt, label, status, expect_structured) that queues a prompt for the rail to send.
Q11Multiple choice
What does transcript_display_config() add to a rail-based UI?#
Answer
A — transcript_display_config() renders the display-settings popover with Last-messages/First-n-characters controls.
Q12Multiple choice
What must app_dir point to for app_viewer() to work correctly?#
Answer
B — app_viewer(app_dir, ...) requires a folder with streamlit_app.py (or the script_name override); it must never point at the host app's own directory.
Q13Multiple choice
What does the "Fix with CoCo" button in app_viewer() do by default?#
Answer
B — The Fix action calls on_fix with a prompt from default_fix_prompt(traceback, app_dir), normally queuing a CoCo job.
Q14Multiple choice
How many app_viewer() previews are meant to point at the same app_dir at once?#
Answer
B — The documented limitation is one preview per app_dir.
Q15Multiple choice
Which CocoOptions field controls how long the app waits for a human decision on a pending approval before raising an error?#
Answer
B — approval_timeout_seconds (default 600.0, i.e. 10 minutes) governs the HITL wait before ApprovalTimeoutError.
Q16Multiple choice
What is the default CocoOptions.permission_mode?#
Answer
C — CocoOptions.permission_mode defaults to "default"; "plan" is used explicitly for ExitPlanMode flows.
Q17Multiple choice
Which function probes the environment (SDK install, CLI reachability, Snowflake config) without starting an agent, and never raises?#
Answer
B — check_environment() is the non-raising probe; require_environment() raises typed errors instead.
Q18Multiple choice
If toml_file is not passed and there is exactly one *.toml file under ~/.snowflake/, what happens?#
Answer
B — When exactly one *.toml exists under ~/.snowflake/, it is used regardless of its filename.
Q19Multiple choice
With several *.toml files under ~/.snowflake/ and no toml_file given, what is the selection order?#
Answer
B — With multiple files, connections.toml wins first, then config.toml, then alphabetical order.
Q20Multiple choice
What does examples/structured_output.py demonstrate?#
Answer
A — structured_output.py shows output_schema + on_structured_output routing JSON into a widget instead of chat text.
Q21Multiple choice
What does examples/headless_pipeline.py demonstrate?#
Answer
B — headless_pipeline.py is pure async Python using query()/CocoSession, with no Streamlit import.
Q22Multiple choice
What kind of demo is examples/approval_gate.py?#
Answer
C — approval_gate.py demonstrates the legacy CCv2 chat() all-in-one component.
Q23Multiple choice
What is distinctive about examples/backlog_desk/, compared to the other example apps?#
Answer
A — backlog_desk is the first rail-based, no-SQL example, backed by local JSON files.
Q24Multiple choice
In examples/backlog_desk/, how is its Copilot opened?#
Answer
C — Its Copilot is opened from a header "Copilot" button or an action link and closed with "Close" — it is not a navigation page.
Q25Multiple choice
What kinds of source files does examples/bi_to_semantic/ read as input?#
Answer
B — bi_to_semantic reads Tableau .twb/.twbx and/or Power BI .pbix/.pbit workbooks.
Q26Multiple choice
Where do files uploaded via upload_to_cwd() / cwd_uploader() / chat_input_bar(accept_file=...) land by default?#
Answer
A — Upload helpers write into <CocoOptions.cwd>/_uploads/ by default (subdirectory name configurable).
Q27Multiple choice
What does the App Builder "Build" step write into examples/app_builder/out/<slug>/?#
Answer
B — The Build step writes brief.json, BRIEF.md, sketches/*, and streamlit_app.py into out/<slug>/.
Q28Multiple choice
Where does the release build's SBOM get published?#
Answer
B — The SBOM (CycloneDX) is attached to GitHub Release assets and is produced only in CI, on tag release.
Q29Multiple choice
What does render_approvals() present, and in what button order?#
Answer
B — render_approvals() orders its controls Approve once, Always allow, Deny.
