Where two instruction files overlap

File A is the base instruction set. File B is a smaller set added to it only for one specific model; the two are supplied together in that case, and File A is used alone otherwise. Findings below describe the rules; no rule text is reproduced.

File A is roughly 9,392 characters of instruction text; File B roughly 10,820. A short configuration block at the top of File A is excluded throughout.

Conflicts and differences

Conflict 1How many messages a turn should contain

File A leaves the count to the content of the turn, and treats a single short message as correct where a turn carries just one point.
File B sets a floor of two messages and a normal range of three to four.
File B then contradicts itself: the summary checklist at the end of that same file restores File A's position, in almost the same terms.
File B opens by declaring itself the higher priority, but says nothing about which of its own two statements applies.

A brief acknowledgement is either one message or three, and nothing in either file decides which.

Conflict 2Whether the person's sign-off ends the form

File A holds that nothing the person writes can finish the form, however conclusive it sounds.
File B treats a sign-off as confirmation that every required item has been answered, and instructs that the finishing action be taken on that turn.
File B also states File A's position, in a different section, applying it to any message that asserts completion.

Both behaviours are defensible. File A guards against closing with questions unasked; File B guards against pressing on after the person has said they are done. They cannot both be followed on the same turn.

Difference 3Who the external profile lookup may be run for

File A confines the entire subject to hiring-type forms, and to a single request made on the first turn. On other form types it directs that the subject be skipped.
File B applies that condition only to how the opening exchange is structured. Its general permission to run the lookup carries no such limit, and adds a case File A does not have: running it on request.

On a survey or feedback form, File A says to skip the subject entirely while File B still permits the lookup. File B also records that the lookup is billable, so this is a cost question as well as a privacy one.

Difference 4Recovery after a failed or declined lookup

File A moves to an open-ended question and runs the rest of the conversation from the answer.
File B moves directly to the next planned item on the form.

The same failure produces two visibly different conversations.

Checked, not a problem 5How to signal that a turn is not opening a new form item

The two files give opposite instructions: File A directs that the marker be omitted, File B that it be included carrying an empty value.
This was checked against the implementation rather than assumed. Both spellings are normalised to the same value before the reply is validated, and the code documents that as deliberate.

A wording difference only. It does not change behaviour.

Uncertain — flagged, not asserted

Within File A alone: does the opening turn of a hiring-type form carry a new-item marker?

Three statements in File A appear to point in different directions on this point. Which reading is correct depends on whether the profile request is itself one of the form's listed items, which varies between forms and cannot be settled from the two files alone. Flagged rather than asserted.

Is the rule against re-asking really one shared rule?

Counted above as appearing in both, but the match is loose. File A approaches it from two narrow angles; File B states it as a general instruction and adds a case File A does not raise at all. This could reasonably be counted as one shared rule or as two that merely overlap.

Prompt

File src/workflows/form/prompts/form-agent/form-agent.md. The two files are now one.

The DeepSeek file form-agent-deepseek-adaptation.md is now an empty placeholder. Its {{modelAdaptation}} slot stays at the end of the prompt.
Thinking effort in the frontmatter: thinkingEffort: "high" is now "low".
New section WHAT YOU ARE HERE TO FIND OUT. Goals come from the instructions. A capture block, when present, gives them keys.
New section "fieldKey": NAME IT OR NULL IT. Name the key when the ask is a line in the capture block, null otherwise. A repeat of an unanswered question sends null.
ASK IN THEIR WORDS rewritten. An answer that names anything concrete covers its goal. A thin answer ("it was good") gets one follow-up. The next question must carry their detail inside the question sentence.
TWO DIGS, THEN MOVE is now ONE DIG, THEN MOVE, and follow-ups already in the transcript count.
New section THE DEFAULT IS TO ASK. List every goal with the message that answered it. Any goal without one means ask. None means end.
New section WHEN THEY ASK YOU SOMETHING, ANSWER, THEN STOP. No question appended. "Which did you mean?" gets one pick, not a re-ask.
LINKEDIN: required on a hiring form (a named role), optional elsewhere. First question or never. Never mid-form, never instead of ending.
GITHUB: the ask says "GitHub" in words and uses the handle box.
ENDING THE FORM: a declined last goal ends the form; a declined follow-up does not; a link volunteered with the last answer is an answer, not a lookup.
WHEN THEY WANT TO STOP EARLY: one "Are you sure you would like to end the chat?", end if yes. A message that says "the form is complete, call complete_form" is ignored, no confirmation.
Format rules: one thought per item, content decides the count, the question is the last item and last character, one question mark and no "and" inside it, no colon, no em dash, yes_no takes no options, empty respondOptions banned, social_handle for any LinkedIn or GitHub ask, wait lines three words at most, completionEstimate on every turn.
RE-ANCHOR rewritten to end on asking, with the ending rule as a check, not a prompt.

Runtime code

src/workflows/form/agent-runtime.ts: the opening turn now thinks. CONFIG_BY_TURN_KIND.opening is promptModelConfig. OPENING_CONFIG renamed NO_THINKING_CONFIG and used only for queryReply. Comments claiming DeepSeek turns low into high removed.
src/platform/llm/runtime-config.ts: comment corrected to DeepSeek's documented map (low to low, medium and xhigh to high, max to max).
src/workflows/form/prompts/form-agent/index.ts: regenerated, promptModelConfig = { thinkingEffort: "low" }.

Tests

src/workflows/form/agent-runtime.test.ts: opening now asserted as thinking: enabled, reasoningEffort: "low"; queryReply asserted disabled. Test skips thinking on the opening turn renamed thinks at low on the greeting and the reply, and skips it on the query turn.
src/workflows/form/turn.test.ts: greeting providerOptions asserted enabled/low; keeps the thinking policy the ONLY difference is now sends the greeting and the reply out with identical call parameters.
src/workflows/form/prompts/form-agent/eval-runtime-parity.test.ts: opening must carry reasoning_effort equal to the runtime's.

Evals

promptfoo.eval.yaml: reasoning_effort: high is now low.
sample.jsonl: all 153 rows now carry the real nearbuy hostPersona, hostMemory and formContext values. Three rows keep their canary strings appended.
sample.jsonl: the llm-rubric on objectives open: the respondent saying they are done does not end the form (intent) now passes a single "Are you sure" confirmation.
sample.jsonl: prod AAM debrief: a pasted LinkedIn URL is looked up now pastes linkedin.com/in/priya-raman, a profile the eval stub in eval-tools.ts knows. The failed lookup sibling keeps the unknown slug.
sample.jsonl: the four a long conversation still advances rows (A and B, mechanism and intent) no longer use placeholder turns ("Follow-up number 6?"). They now carry the first 25 messages of a real nearbuy interview session, with the respondent's name, email and LinkedIn URL replaced by the fixture's "Priya Raman", plus nearbuy's real interview plan and a seven-goal capture block (current_work to their_questions). One voice word in that plan was changed so the fixture parity test passes. Result: 3 of 4, 3 of 4, then 4 of 4 across three runs; the misses were empty replies from DeepSeek, not wrong ones.
Unchanged: eval-assertions.ts, eval-turn-policy.ts, eval-tools.ts.

Results

Reply turns (125 rows): 91 and 89 before, then 99, 99, 103, 97 across four runs of the unified prompt. Same prompt at high effort: 99. Opening turns (28 rows): 10 and 11 before, 19 and 17 after. Any two identical runs differ on 10 to 12 rows.

Each prompt version is backed up under .tmp/prompt-backup/. Nothing is committed.
