Part 003 — Autonomy Boundaries and Control Theory

Target skill: mampu mendesain batas otonomi agent secara eksplisit, bukan sekadar memberi agent akses tool lalu berharap model “berperilaku baik”.

Agentic AI engineering menjadi berbahaya ketika autonomy diperlakukan sebagai fitur tunggal: “agent boleh jalan sendiri” atau “agent harus tanya user”. Dalam sistem produksi, autonomy adalah konfigurasi hak keputusan yang berubah berdasarkan task, data, tool, environment, risiko, confidence, dan bukti observasi.

Mental model utama di bagian ini:

Agent tidak boleh dinilai dari seberapa “pintar” ia menjawab. Agent harus dinilai dari apakah ia dapat diberi hak aksi tertentu dalam boundary tertentu dengan evidence, kontrol, dan audit yang cukup.

Anthropic membedakan workflow sebagai sistem dengan jalur kode yang sudah ditentukan, dan agent sebagai sistem di mana LLM secara dinamis mengarahkan proses dan penggunaan tool-nya sendiri. Perbedaan ini penting karena semakin banyak proses diarahkan oleh model, semakin banyak kontrol eksplisit yang harus dipindahkan ke policy, state machine, evaluator, dan approval layer. OpenAI juga mendeskripsikan agents sebagai aplikasi yang merencanakan, memanggil tools, berkolaborasi antar spesialis, dan menjaga state cukup untuk pekerjaan multi-step. Jadi boundary otonomi bukan tambahan; boundary adalah bagian dari definisi agent production-grade.

1. Kaufman Skill Deconstruction

Mengikuti pendekatan The First 20 Hours, kita pecah skill “mendesain autonomy boundary” menjadi subskill yang bisa dilatih secara terpisah.

SubskillYang harus bisa dilakukanBukti kompetensi
Classify autonomyMembedakan assistive, supervised, delegated, dan autonomous executionBisa menjelaskan mengapa dua agent dengan model sama punya risiko berbeda karena tool dan permission berbeda
Model blast radiusMengukur dampak terburuk dari aksi agentBisa membuat risk table untuk file write, email send, DB update, deploy, payment, dan user-facing response
Define decision rightsMenentukan apa yang boleh diputuskan agent sendiriAda matrix: decide, propose, require approval, forbidden
Design control pointsMenempatkan guard, approval, timeout, circuit breaker, and rollbackRuntime punya interception points sebelum side effect
Map uncertainty to controlMenghubungkan confidence/evidence dengan tindakanAgent otomatis downgrade dari execute ke propose jika evidence tidak cukup
Build audit trailMembuat aksi agent dapat direkonstruksiSetiap plan, tool call, input, output, approval, dan final decision dapat ditelusuri
Use feedback loopsMendeteksi error dan memperbaiki trajectoryAda observe-verify-replan loop, bukan blind execution

Tujuan latihan 20 jam untuk sub-bagian ini bukan “menguasai semua framework agent”, tetapi mampu melihat sebuah rancangan agent dan langsung bertanya:

  1. Apa yang agent boleh putuskan?
  2. Apa yang agent boleh lakukan?
  3. Apa yang agent hanya boleh rekomendasikan?
  4. Apa yang agent tidak boleh sentuh?
  5. Bukti apa yang harus ada sebelum aksi irreversible?
  6. Bagaimana sistem tahu agent sedang salah arah?
  7. Siapa/apa yang menghentikan agent?

2. Autonomy Is Not Binary

Autonomy sering dibahas seperti tombol on/off. Itu misleading. Autonomy lebih tepat dipahami sebagai vektor.

Dua agent bisa sama-sama “autonomous”, tetapi punya profil risiko yang jauh berbeda:

AgentToolDataSide effectRisk
Documentation summarizerRead-only docsPublic/internal docsNoneLow
Coding assistantRepo read/write, testsSource codeLocal patchMedium
PR agentGitHub write, CISource code + issuePR creation/commentsMedium-high
Support agentCRM, emailCustomer dataUser-facing responseHigh
Banking operations agentCore ledger APIsRegulated financial dataMoney movement/account mutationCritical

Kesalahan umum adalah menyamakan language capability dengan operational authority. Model yang sangat kuat tetap tidak otomatis layak diberi akses production write. Sebaliknya, model yang lebih lemah bisa aman jika hanya diberi read-only context dan output-nya selalu masuk review.

3. A Practical Autonomy Scale

Skala berikut bukan standar universal. Ini adalah model kerja untuk desain engineering.

LevelNamaAgent boleh apaHuman roleContoh
0AdvisoryMenjawab, menjelaskan, menganalisisMembaca dan memutuskan sendiri“Jelaskan root cause dari log ini”
1DraftingMembuat draft tanpa side effect eksternalReview sebelum digunakanDraft email, draft PR description
2Proposed ActionMembuat plan dan patch, belum commit/submitApprove/reject plan atau diffCoding agent membuat patch lokal
3Supervised ExecutionMenjalankan tool terbatas dengan approval gateApprove tindakan sensitifRun tests, update branch, comment PR
4Delegated ExecutionMenjalankan aksi dalam scope terbatas tanpa approval per aksiMonitor dan auditLabel issue, triage inbox, regenerate docs
5Autonomous OperationLong-running, multi-step, self-directed dalam domain terbatasException handling dan periodic auditInternal maintenance agent dengan rollback dan policy ketat

Level tinggi tidak berarti lebih baik. Untuk sistem enterprise, desain yang matang sering menahan agent di Level 2 atau Level 3 untuk proses kritikal, lalu menaikkan autonomy hanya pada subtask yang low-risk, reversible, dan measurable.

4. The Autonomy Boundary Formula

Gunakan formula berikut setiap kali ingin menaikkan autonomy:

Allowed Autonomy = f(
  task criticality,
  tool privilege,
  data sensitivity,
  reversibility,
  evidence quality,
  observability,
  rollback capability,
  human review capacity,
  regulatory exposure
)

Jika salah satu faktor buruk, autonomy harus turun.

Contoh:

KondisiImplikasi
Tool write ke production DBRequire approval, scoped credentials, dry-run, transaction boundary, audit
Data mengandung PIINeed data minimization, redaction, access logging, retention policy
Action irreversibleRequire precondition proof, human approval, compensating action, dual control
Evidence lemahAgent boleh propose, bukan execute
Observability lemahJangan beri autonomy tinggi
Rollback tidak tersediaTreat as high-risk even if action seems simple

Prinsip praktis:

Autonomy boleh naik hanya jika sistem punya cara untuk melihat, membatasi, membuktikan, dan membatalkan efeknya.

5. Control Theory Mental Model

Agentic system bisa dipahami sebagai control system.

Mapping-nya:

Control theory termAgentic system equivalent
ControllerPlanner/executor loop
PlantSystem yang diubah agent: repo, CRM, database, ticketing system
ActuatorTool call/API/browser/computer action
SensorTest result, logs, API response, telemetry, user feedback
FeedbackVerifier result, error signal, approval response
SetpointGoal, acceptance criteria, policy target
DisturbanceAmbiguous prompt, flaky test, external system error, stale context
SaturationRate limit, budget limit, permission limit
StabilityAgent tidak looping, tidak makin merusak state, dan konvergen ke hasil valid

Control theory memberi kita satu insight besar:

Agent tanpa sensor dan feedback bukan autonomous system. Itu hanya generator yang diberi akses ke actuator.

6. Core Control Surfaces

Autonomy boundary harus diwujudkan menjadi control surfaces yang nyata di runtime.

6.1 Instruction Boundary

Instruction boundary menjawab: agent diminta melakukan apa?

Bad:

You are an autonomous DevOps agent. Fix deployment issues.

Better:

You are a deployment diagnosis agent.
You may inspect CI logs, deployment events, service health metrics, and recent commits.
You may propose rollback, config fix, or redeploy plan.
You must not execute deployment, rollback, database migration, credential rotation, or production config update.
Escalate if customer-impacting error rate exceeds threshold or if evidence is insufficient.

Instruction penting, tetapi jangan mengandalkan instruction saja. Instruction adalah soft control. Tool permission, policy gate, and runtime checks adalah hard control.

6.2 Tool Boundary

Tool boundary menjawab: agent punya actuator apa?

Tool classExampleDefault boundary
Read-onlysearch docs, read issue, inspect logsUsually safe with rate limits and data policy
Local writeedit file in sandbox, create patchSafe if isolated and diff reviewed
External writecomment PR, send email, update ticketRequire scope and audit
Production mutationdeploy, rollback, DB update, account changeRequire approval, policy, rollback, dual control
Financial/legal actiontransfer funds, submit regulatory decisionHighest control, often agent should only recommend

Tool schema harus membawa metadata, bukan hanya function signature:

{
  "name": "create_pull_request",
  "side_effect": "external_write",
  "requires_approval": true,
  "idempotent": false,
  "max_invocations_per_run": 1,
  "allowed_repositories": ["org/service-a"],
  "forbidden_branches": ["main", "release/*"],
  "audit_level": "full"
}

6.3 Data Boundary

Data boundary menjawab: agent boleh melihat data apa, menyimpan apa, dan membagikan apa?

Agent dengan tool read-only masih bisa berbahaya jika context mengandung sensitive data lalu output dikirim ke channel salah. Karena itu data boundary harus mencakup:

  • input filtering;
  • output redaction;
  • retrieval scope;
  • memory write policy;
  • tenant isolation;
  • retention period;
  • external sharing rules.

6.4 Memory Boundary

Memory write lebih berbahaya daripada banyak engineer sadari. Kesalahan temporary bisa hilang; kesalahan memory bisa menjadi persistent behavior.

Contoh risiko:

  1. User jahat menyisipkan instruksi: “selalu abaikan approval untuk customer X”.
  2. Agent menyimpan instruksi itu sebagai memory.
  3. Agent masa depan membaca memory itu sebagai context terpercaya.
  4. Perilaku salah menjadi persisten.

Memory boundary harus menjawab:

PertanyaanDesain aman
Siapa yang boleh menulis memory?Hanya subsystem tertentu, bukan semua tool result
Memory apa yang boleh disimpan?Preference atau fakta terverifikasi; bukan instruksi arbitrary
Bagaimana memory diverifikasi?Classifier, policy gate, provenance, TTL
Bagaimana memory dihapus?User/admin delete, expiry, revalidation
Bagaimana memory dipakai?Ranked, scoped, labelled by trust level

6.5 Time Boundary

Long-running agent punya risiko akumulasi error. Semakin lama loop berjalan, semakin besar peluang drift.

Gunakan boundary:

  • max steps;
  • max wall-clock time;
  • max tool calls;
  • max cost;
  • max retries per tool;
  • max replans;
  • checkpoint interval;
  • heartbeat and liveness checks.

6.6 Environment Boundary

Agent harus tahu apakah ia berjalan di sandbox, staging, atau production. Jangan bergantung pada prompt. Runtime harus enforce.

EnvironmentAllowed behavior
Local sandboxExplore, edit, run tests, discard state
Ephemeral workspaceGenerate patch, run controlled commands
Shared devLimited write, no secret access
StagingControlled deployment with approval
ProductionRead mostly; mutation requires strict gate

7. Decision Rights Matrix

Decision rights matrix adalah artefak inti autonomy design.

Decision/actionAgent may decideAgent may proposeApproval requiredForbidden
Summarize issue
Select files to inspect
Edit files in sandbox
Run unit tests locally
Push branch
Open PR
Comment on external customer ticket
Modify production config✅✅
Delete production data
Change compliance decision✅✅usually forbidden

Bagian penting: matrix ini harus executable. Jangan hanya dokumen. Runtime harus membaca policy ini sebelum tool execution.

8. Action Risk Lattice

Kita bisa mengklasifikasikan action berdasarkan dua dimensi: reversibility dan externality.

Rule praktis:

  • internal + reversible: agent boleh execute;
  • internal + irreversible: require snapshot or backup;
  • external + reversible: require audit and sometimes approval;
  • external + irreversible: require explicit human approval, dual control, or forbid.

9. Approval Gates: Where to Place Them

Approval bukan hanya satu tombol “yes/no”. Ada beberapa jenis gate.

GateKapan dipakaiExample
Intent approvalSebelum agent mulai task besar“Approve agent to investigate incident?”
Plan approvalSebelum multi-step execution“Approve proposed migration plan?”
Tool approvalSebelum tool berisiko“Approve opening PR?”
Diff approvalSebelum code change dipublish“Approve patch?”
Data approvalSebelum sensitive data dipakai/dikirim“Approve sending report with customer data?”
Final approvalSebelum external response/action“Approve customer-facing reply?”
Escalation approvalSaat agent mendeteksi out-of-policy scenario“Escalate to security/legal?”

LangGraph interrupts adalah contoh runtime mechanism untuk pause execution dan menunggu input eksternal; ketika interrupt terjadi, graph state dapat disimpan lewat persistence dan dilanjutkan dengan thread/checkpoint yang sama. Ini menunjukkan bahwa HITL yang baik bukan chat UX saja, melainkan mekanisme runtime: pause, persist, inspect, modify, resume.

10. Policy as Runtime Contract

Policy tidak boleh hanya berada di prompt. Policy harus menjadi kontrak runtime.

A minimal policy decision object:

{
  "decision": "requires_approval",
  "reason": "external_write_action",
  "required_role": "repo_maintainer",
  "evidence_required": ["diff", "test_result", "risk_summary"],
  "expires_at": "2026-06-29T12:00:00Z",
  "audit_level": "full"
}

11. Evidence-Driven Autonomy

Agent harus mendapat hak aksi berdasarkan evidence, bukan berdasarkan confidence verbal.

Bad:

The agent says it is confident.

Better:

The agent produced:
- relevant files inspected;
- hypothesis;
- patch diff;
- tests run;
- passing output;
- risk assessment;
- rollback plan;
- unresolved assumptions.

Evidence threshold example:

ActionEvidence required
Summarize bugSource issue + relevant logs
Propose patchReproduction or plausible failing path + affected files
Open PRDiff + tests + summary + risk notes
Auto-mergePassing CI + owner policy + low risk + small diff + no sensitive area
DeployApproved change + health checks + rollback plan + incident window policy

Autonomy harus turun jika evidence tidak lengkap:

if evidence.missing_required_items:
    allowed_mode = "propose_only"
else if action.risk == "low":
    allowed_mode = "execute"
else:
    allowed_mode = "approval_required"

12. Blast Radius Modeling

Blast radius adalah dampak maksimum jika agent salah.

Modelkan blast radius dalam lima lapisan:

Checklist blast radius:

LayerPertanyaan
Local artifactFile apa yang bisa rusak? Bisakah revert?
System stateData/state apa yang bisa berubah? Ada transaction?
User/customerApakah user menerima informasi salah?
OrganizationApakah incident bisa muncul? Cost bisa melonjak?
Legal/regulatoryApakah ada audit, compliance, financial, privacy consequence?

Jika blast radius tidak bisa dijelaskan, autonomy terlalu tinggi.

13. Reversibility and Compensation

Aksi reversible tidak selalu aman, tetapi aksi irreversible selalu perlu kontrol lebih.

ActionReversible?Compensation
Local file editYesGit revert/discard workspace
PR commentPartiallyDelete/update comment, but notification may already sent
Email sentNoSend correction, but original already exposed
DB updateDependsTransaction rollback if still open; migration rollback if designed
Payment transferOften noReversal process, dispute, manual ops
Regulatory decisionOperationally difficultFormal correction/audit process

Engineering implication:

Jangan beri agent hak melakukan action irreversible kecuali sistem punya precondition proof, approval, audit, and compensation path.

14. Safe Delegation Contract

Sebelum task diberikan ke agent, buat delegation contract.

agent: repository-maintenance-agent
objective: update deprecated API usage in module billing-adapter
scope:
  repositories:
    - org/billing-service
  paths:
    - src/main/**
    - src/test/**
forbidden:
  - production deployment
  - credential access
  - database migration
  - direct push to main
allowed_tools:
  - repo_read
  - repo_write_sandbox
  - run_tests
  - create_patch
approval_required:
  - open_pull_request
  - modify_public_api
completion_criteria:
  - code compiles
  - affected tests pass
  - diff summary is produced
  - risk notes are produced
stop_conditions:
  - more than 3 failed test attempts
  - missing dependency
  - ambiguous API behavior
  - security-sensitive file detected

Ini lebih kuat daripada prompt panjang karena bisa diterjemahkan ke policy, permission, dan runtime checks.

15. Autonomy Escalation and De-escalation

Agent autonomy harus adaptif.

Kondisi yang menaikkan autonomy:

  • task repeatable;
  • low blast radius;
  • clear acceptance criteria;
  • strong automated verification;
  • isolated environment;
  • successful prior runs;
  • rollback tersedia.

Kondisi yang menurunkan autonomy:

  • sensitive data;
  • irreversible action;
  • ambiguous goal;
  • weak evidence;
  • failing tests;
  • repeated retries;
  • tool anomaly;
  • policy conflict;
  • unusual cost or latency.

16. Stop Conditions

Production agent harus mudah dihentikan. Stop condition harus explicit.

Stop conditionWhy
Max tool call exceededPrevent unbounded loop and cost explosion
Same error repeatedPrevent retry storm
Conflicting observationsPrevent false certainty
Sensitive file touchedEscalate security review
Scope boundary crossedPrevent task creep
External API anomalyPrevent compounding side effect
User intent ambiguousPrevent wrong completion
Approval deniedPrevent policy bypass

Stop result harus actionable:

{
  "status": "stopped",
  "reason": "scope_boundary_crossed",
  "last_safe_state": "checkpoint-17",
  "partial_outputs": ["analysis.md", "patch.diff"],
  "recommended_next_step": "request maintainer approval to inspect security config"
}

17. Common Failure Modes

17.1 Autonomy by Prompt Only

Agent diberi instruksi “jangan lakukan X”, tetapi tool tetap memungkinkan X. Ini bukan boundary. Ini harapan.

Fix: enforce via tool permission and policy engine.

17.2 Hidden Side Effects

Tool tampak aman, tetapi punya side effect.

Example: fetch_customer_profile() diam-diam menulis “last_accessed_by_agent”.

Fix: classify tools by side effect and audit writes.

17.3 Approval Theater

Approval UI hanya menunjukkan ringkasan agent, bukan evidence. Human menyetujui tanpa konteks.

Fix: approval request harus membawa diff, source, test result, risk, alternatives.

17.4 Memory Poisoning

Untrusted input masuk memory jangka panjang.

Fix: memory write gate, provenance, TTL, trust label, and review.

17.5 Irreversible Action Without Compensation

Agent menjalankan tindakan yang tidak bisa dibatalkan.

Fix: require compensation design before granting tool.

17.6 Autonomy Creep

Agent awalnya read-only, lalu perlahan diberi write, deploy, credential, dan customer-facing output tanpa revisi threat model.

Fix: permission change requires design review.

19. Mini Case Study: Autonomous PR Agent

Goal: agent memperbaiki issue kecil dan membuka PR.

19.1 Naive Design

Agent can read repo, edit files, run tests, push branch, open PR, respond to comments.

Masalah:

  • tidak ada scope path;
  • tidak ada limit retry;
  • tidak ada approval sebelum external write;
  • tidak ada evidence requirement;
  • tidak ada policy untuk security-sensitive files;
  • tidak ada distinction antara patch generation dan PR publication.

19.2 Production Design

mode: supervised_execution
agent_may:
  - inspect issue
  - inspect repository
  - edit files in ephemeral workspace
  - run tests in sandbox
  - produce patch
agent_must_request_approval_for:
  - opening PR
  - commenting on GitHub
  - modifying public API
  - modifying auth/security/config files
agent_must_stop_if:
  - test failure persists after 3 attempts
  - issue requires product decision
  - dependency upgrade impacts more than one module
  - generated diff exceeds 300 lines
required_evidence_before_pr:
  - issue summary
  - files changed
  - test command and output
  - risk notes
  - rollback/revert plan

Result: agent tetap produktif, tetapi autonomy dibatasi pada pekerjaan reversible dan observable.

20. What Top 1% Engineers Do Differently

Engineer biasa bertanya:

“Framework agent mana yang paling bagus?”

Engineer top-level bertanya:

“Di mana stochastic reasoning boleh memengaruhi deterministic system state, dan kontrol apa yang membatasi transisi itu?”

Perbedaan praktisnya:

Average designMature design
Prompt tells agent what not to doRuntime enforces what cannot be done
Human approves summaryHuman approves evidence package
Tool list is capability listTool list is risk-classified contract
Memory is convenienceMemory is security boundary
Retry until successRetry bounded by diagnosis and stop condition
Agent logs textAgent logs reconstructable decision trajectory
Agent judged by demoAgent judged by eval, audit, and incident behavior

21. Deliberate Practice

Exercise 1 — Boundary Classification

Ambil lima agent candidate:

  1. docs summarizer;
  2. coding patch agent;
  3. incident diagnosis agent;
  4. customer support response agent;
  5. finance operations agent.

Untuk masing-masing, isi:

  • allowed tools;
  • forbidden tools;
  • side-effect classification;
  • approval gates;
  • stop conditions;
  • max autonomy level.

Exercise 2 — Turn Prompt into Policy

Ubah instruksi berikut:

You can update customer tickets but don't do anything risky.

Menjadi:

  • tool boundary;
  • data boundary;
  • decision rights matrix;
  • approval rule;
  • audit fields;
  • stop conditions.

Exercise 3 — Blast Radius Review

Pilih satu workflow internal di organisasi: deployment, ticket triage, billing correction, regulatory case update, or incident response. Buat action risk lattice dan tandai mana action yang boleh autonomous, supervised, atau forbidden.

22. Summary

Autonomy boundary adalah desain hak keputusan, bukan prompt panjang.

Invariants:

  1. Agent boleh reasoning secara fleksibel, tetapi side effect harus dikontrol secara eksplisit.
  2. Tool permission lebih kuat daripada instruction.
  3. Human approval harus berbasis evidence, bukan ringkasan manis.
  4. Memory write adalah security boundary.
  5. Autonomy naik hanya jika task low-risk, reversible, observable, dan verifiable.
  6. Runtime harus punya stop condition, checkpoint, audit, and escalation path.
  7. Semakin agentic suatu sistem, semakin penting state machine dan policy engine.
