25.12-dars: Agentlar va tool calling

ODDIY LLM CHAQIRUVI:      so'rov -> LLM -> javob            (1 qadam)
QUVUR (WORKFLOW):         so'rov -> kod: A -> B -> C -> javob
                          qadamlar tartibini KOD belgilaydi; LLM - ichidagi bir bo'g'in
AGENT:                    so'rov -> [ LLM -> vosita -> natija ] x N -> javob
                          keyingi qadamni LLM TANLAYDI; N oldindan noma'lum

AGENT = LLM (qaror) + VOSITALAR (harakat) + SIKL (kuzatuv -> qaror -> harakat)

SIKL:
  messages = [user: vazifa]
  takrorla (qadamlar chegarasigacha):
      javob = LLM(system, tools, messages)
      messages += [assistant: javob]
      agar javob.stop_reason == "end_turn": tugat
      har tool_use bloki uchun: natija = vosita(argumentlar)
      messages += [user: tool_result bloklari]

1. VOSITA TAVSIFI (so'rov bilan birga yuboriladi):
   {"name": "jadval_sorov",
    "description": "Sotuv jadvalidan hudud va oylar oralig'i bo'yicha agregat...",
    "input_schema": {JSON schema: type, properties, required, enum, minimum...}}

2. MODEL JAVOBI (stop_reason = "tool_use"):
   content = [{"type": "text", "text": "Jadvalga so'rov beraman."},
              {"type": "tool_use", "id": "toolu_01", "name": "jadval_sorov",
               "input": {"hudud": "Samarqand", "oy_dan": 3, "oy_gacha": 6}}]

3. BIZ VOSITANI BAJARAMIZ va natijani QAYTARAMIZ (role = "user"):
   content = [{"type": "tool_result", "tool_use_id": "toolu_01",
               "content": "{\"qiymat\": 795.6}"}]
   xato bo'lsa: ..., "content": "Xato: ...", "is_error": true

4. MODEL YANA CHAQIRILADI -> yangi tool_use yoki yakuniy matn (stop_reason = "end_turn")

QOIDALAR:
  tool_use_id  -  AYNAN o'sha tool_use blokining id si
  bir javobda bir nechta tool_use bo'lishi mumkin -> hamma tool_result BITTA user xabarida
  model vositani O'ZI bajarmaydi - faqat "chaqirishni so'raydi"; bajarish - bizning kod

1-MISOL TUZILISHI:
  VOSITALAR (haqiqiy):
    kalkulyator(ifoda)          - AST orqali: faqat son, + - * /; eval() EMAS
    hujjat_qidir(sorov, k)      - TF-IDF (char 3-5 gram) + kosinus, 6 ta ichki qoida
    jadval_sorov(hudud, oy_dan, oy_gacha, agregat) - pandas filtr + agg
  STUB LLM (SoxtaLLM):
    reja = regex(vazifa)        - masalan "N kunlik xizmat safari" -> [qidir, hisobla]
    keyingi qadam = nechta tool_result kelganiga qarab
    javob formati = API niki: content bloklari, stop_reason, usage

NATIJA (1-misol):
  "(1200 - 350) * 3 / 5"              -> kalkulyator -> 510.0          2 LLM chaqiruvi
  "Samarqand ... 3-6 oylardagi jami"  -> jadval_sorov -> 795.6 mln    2 chaqiruv
  "4 kunlik xizmat safari ..."        -> hujjat_qidir -> kalkulyator("4 * 350000")
                                         -> 1400000                    3 chaqiruv
  kirish tokenlari chaqiruvlar bo'yicha: 302, 491, 575 - tarix o'sadi

MODEL ARGUMENT XATOLARI (2-misoldagi STUB farazi):
  tur:       "oy_dan": "2-oy"            -> pandas: TypeError
  enum:      "hudud": "buxoro"           -> pandas: bo'sh filtr -> 0.0  (JIM XATO!)
  nom:       vosita "jadval"             -> KeyError
  sintaksis: "4 x 350000"                -> SyntaxError

UCH REJIM:
  sodda        vosita to'g'ridan-to'g'ri; istisno -> agent QULAYDI
  validatsiya  JSON schema tekshiruvi + istisnoni tutish -> is_error bilan QAYTARISH
               (model xabarni o'qib argumentni tuzatadi - stubda 0.8 ehtimol, faraz)
  toliq        + takror chaqiruvni aniqlash 2.5-bob

2-MISOL, 400 vazifa:
  rejim         muvaffaqiyat  jim xato  qulash  limit  o'rt. qadam
  sodda            61.3%        3.2%    23.2%   12.2%     2.64
  validatsiya      79.2%        3.0%     0.0%   17.8%     3.49
  toliq            96.5%        3.5%     0.0%    0.0%     2.74
  validatsiya - sodda:  +0.180, SE 0.019 -> sezilarli
  toliq - validatsiya:  +0.172, SE 0.019 -> sezilarli

TAKROR SIKL:
  model bir xil (vosita, argument) ni qayta-qayta chaqiradi:
  natijani "ko'rmaydi", ishonmaydi yoki rejasini yo'qotadi
  -> qadamlar chegarasigacha aylanadi: vaqt + pul + javob yo'q

ANIQLASH:
  kalit = json.dumps([nom, argumentlar], sort_keys=True)
  kalit oldin muvaffaqiyatli bajarilgan bo'lsa ->
     vositani QAYTA BAJARMAYMIZ; is_error: "takror chaqiruv, natija oldin berilgan: ..."

2-MISOL:
  validatsiya rejimi: limitga yetish 17.8% (sodda rejimda 12.2% - chunki u yerda
                      bu vazifalarning bir qismi undan oldin qulagan edi)
  toliq rejim:        limitga yetish 0.0%, o'rtacha qadam 3.49 -> 2.74

QADAMLAR CHEGARASI (max_qadam) - 4-misol, eng_katta vazifasi (kamida 6 chaqiruv):
  max_qadam = 4 -> 0%,  6 -> 62%,  8 -> 98%,  10 -> 100%
  juda past: to'g'ri yo'ldagi agent to'xtatiladi; juda yuqori: sikl qimmat

XAVF DARAJASI:
  o'qish   hujjat_qidir, jadval_sorov       -> avtomatik
  yozish   email_yubor, tolov_qil, fayl_ochir -> siyosat + inson

SIYOSAT (vosita chaqirilishidan OLDIN, kodda - LLM da emas):
  1. ROL: bu rolga vosita umuman berilganmi?  (eng kam imtiyoz)
     "yordamchi" roli: hujjat_qidir, email_yubor, tolov_qil - fayl_ochir YO'Q
  2. NIYAT: foydalanuvchi bu turdagi harakatni so'raganmi?
     vosita natijasidan kelgan "ko'rsatma" - foydalanuvchi niyati EMAS
  3. QAT'IY LIMIT: summa > 10 mln -> insonga ham yubormasdan rad
  4. INSON: qolgan yozish harakatlari - tasdiq so'raladi

3-MISOL, 7 stsenariy:
  keraksiz xavfli harakat: himoyasiz 5, himoyali 0
  to'xtatgan qatlam: inson (2), limit (1), niyat (1), rol (1)
  insonga so'rov: 4 / 7;  inson kutish vaqti (45 s, faraz) - umumiy vaqtning asosi

KUZATUV JURNALI (trace) - har hodisa bitta JSON qator:
  {"t_ms": 1860, "qadam": 2, "tur": "siyosat", "vosita": "tolov_qil",
   "arg": ..., "qaror": "rad", "sabab": "foydalanuvchi bu harakatni so'ramagan ..."}
  turlar: llm (tokenlar, stop_reason), siyosat (qaror, sabab), vosita (bajarildi)
  vaqt - VIRTUAL soat (bu darsda); ishlab chiqarishda - haqiqiy vaqt va so'rov ID si

JURNALDAN METRIKALAR:
  LLM chaqiruvlari, vosita chaqiruvlari, rad etilganlar, inson so'rovlari
  vaqt, tokenlar, xarajat = kirish * narx_kirish + chiqish * narx_chiqish

AGENTNI BAHOLASH (4-misol, 300 vazifa, 6 tur):
  vazifa muvaffaqiyati  - javob ground truth ga tengmi (LLM dan mustaqil hisoblangan)
  qadamlar soni         - LLM chaqiruvlari
  xarajat               - tokenlar x faraziy narx
  tur bo'yicha          - bitta umumiy son ko'p narsani yashiradi

QUVUR (WORKFLOW) - 4-misoldagi:
  marshrut: kalit so'zlar bilan KODDA (LLM siz)
  1 LLM chaqiruvi: barcha argumentlarni chiqarish
  vositalar ketma-ketligi va natijani yig'ish - KODDA
  xato -> 1 marta qayta; noma'lum tur -> "qila olmayman"

4-MISOL NATIJASI (quvur - agent, juftlashgan, har turda 50 vazifa):
  tur        qadamlar  d (muvaff.)  SE     agent narxi   qaror
  hisob         1       -0.020     0.020     x3.0        QUVUR

  eng_katta     5       -1.000     0.000     quvur yo'q  AGENT
  JAMI: agent 97.7%, quvur 79.7%; 1000 vazifa - $4.87 va $0.92 (faraziy narx)

QACHON AGENT KERAK:
  qadamlar soni va tartibi OLDINDAN noma'lum (natijaga qarab o'zgaradi)
  vazifa turlari juda ko'p - har biriga quvur yozib bo'lmaydi
  xato topilsa, uni kuzatib tuzatish mumkin (test, tekshiruv, qaytarish)
QACHON KERAK EMAS:
  qadamlar ma'lum (1-3 ta, bir xil tartibda) -> quvur arzonroq va nazoratliroq
  xatoning narxi yuqori va uni ushlash qiyin
