forma-sdk 2.3.8

FORMA — AI agent compliance SDK. Zero-config tracking, EU AI Act/DPDP/RBI compliance, cryptographic audit trails.

FORMA SDK — v2.3.0

Make non-compliance impossible — in one line of code.

FORMA doesn't just record what your AI did; it blocks non-compliant decisions before they execute. Add enforce=[...] and PII leaks, prompt injections, and policy violations are stopped at runtime — then every decision is HMAC-signed and mapped to RBI, DPDP, EU AI Act, and ISO 42001.

Install

pip install forma-sdk

Import name is trustlayer:

import trustlayer as tl

Quickstart — runtime enforcement (zero-touch)

import trustlayer as tl

# One call. Enforcement is process-wide on every LLM/tool call — no decorators,
# no context managers, no edits inside your business logic.
tl.init(
    api_key="tl_live_YOUR_KEY",   # from forma.2bd.net → Settings
    human_sponsor="[e-mail]",
    enforce=["rbi_ml_risk", "dpdp"],   # ← blocks violations BEFORE they run
)

# Prove enforcement is live — 4 adversarial probes, no network:
result = tl.verify()
assert result["verified"], f"Gate not working: {result['summary']}"

# Your existing code is unchanged.
result = run_underwriting_model(application)

Now, before any LLM or tool call executes:

• An Aadhaar / PAN / GSTIN / IFSC / Indian Passport / card number → blocked (DPDP)
• "Ignore previous instructions…" / jailbreaks → blocked
• "Auto-approve without review" → blocked (RBI human-review rule)

A blocked action raises ComplianceViolation. The gate runs locally in < 1 ms — no network hop. Tool calls get a 1.25× threat multiplier; dangerous tool names (exec, shell, rm, delete, drop) add a further +0.35.

Init-time validation: enforce=["dpdpp"] (typo) raises ValueError immediately with a link to the docs — misconfigurations are caught before any traffic flows.

Multiple agents — tl.register() / agents= (still zero edits)

Map your existing functions to agents without touching their bodies:

import trustlayer as tl
from my_app import approve_loan, validate_kyc, detect_fraud

tl.init(
    api_key="tl_live_YOUR_KEY",
    agents={
        "kyc-validator":  validate_kyc,                                        # bare callable
        "loan-approval":  {"fn": approve_loan, "enforce": ["rbi_ml_risk", "dpdp"],
                           "risk_level": "HIGH"},
        "fraud-detector": {"fn": detect_fraud, "enforce": ["dpdp"]},
    },
)

# Or register after init (decorator form also works):
tl.register("loan-approval", approve_loan, enforce=["rbi_ml_risk"], risk_level="HIGH")

# Call them exactly as before — each governed and attributed independently.
result = approve_loan(application)

from trustlayer import ComplianceViolation

try:
    result = approve_loan(application)
except ComplianceViolation as e:
    print(e.reason)   # "PII detected in LLM prompt: Aadhaar number. ..."

Observability API (v2.3.0)

Three functions let you inspect the in-process gate from health checks, startup scripts, or unit tests — no network calls needed.

tl.verify() — Prove enforcement is active

Runs 4 adversarial self-test probes against the local gate. Use at startup to confirm the gate is wired before any real traffic flows.

tl.init(api_key="tl_live_...", enforce=["dpdp"])
result = tl.verify()
# → {verified: True, probes_passed: 4, probes_total: 4, summary: "4/4 probes passed — gate is active"}

# Probes (all local — no network):
#   1. Aadhaar PII → must block
#   2. Indian PAN → must block
#   3. Canonical jailbreak → must block
#   4. Clean benign prompt → must allow
#   5. Unauthorized tool (if authorized_actions set) → must block

tl.status() — Real-time enforcement state

Returns a live snapshot of the gate — decision counts, top blocked rules, circuit-breaker state:

s = tl.status()
# → {
#     "version": "2.3.0",
#     "enforcement_active": True,
#     "decisions_total": 1847,
#     "decisions_blocked": 23,
#     "decisions_warned": 4,
#     "decisions_allowed": 1820,
#     "top_rule_hits": {"pii_in_prompt": 18, "threat_prompt_injection": 5},
#     "circuit_breaker_open": False,
#     "kill_switch_active": False,
#     "last_policy_sync": "2026-06-17T10:15:32Z",
#     ...
# }

tl.preview() — Dry-run gate check

Simulate what the gate would decide for any prompt — no side effects, no ComplianceViolation, no audit log entry:

r = tl.preview("My Aadhaar is 1234 5678 9012")
# → {"decision": "block", "rule_id": "pii_in_prompt", "reason": "PII detected: Aadhaar number..."}

r = tl.preview("What is the loan status?")
# → {"decision": "allow", "rule_id": None, "reason": None}

# Test a tool call (higher threat multiplier):
r = tl.preview("drop tables", action_type="tool_call", tool_name="exec_sql")
# → {"decision": "block", ...}

trustlayer verify-decisions — Tamper-evident audit CLI

Every gate decision is HMAC-SHA256 signed before buffering. This CLI command fetches the log and verifies every signature:

trustlayer verify-decisions
# ✓ 47 decisions verified (0 tampered, 0 unsigned)
#   Blocked: 8 | Warned: 3 | Allowed: 36
#   Top rule: pii_aadhaar (5 hits)

trustlayer verify-decisions --agent loan-approval-agent --limit 500
# exits 1 if any decision fails verification — wire into CI

Zero-config tracking (no enforcement)

import trustlayer as tl
tl.init(api_key="tl_live_YOUR_KEY")

# Every OpenAI / Anthropic / LangChain / LiteLLM call is auto-captured —
# tokens, cost, latency, anomaly score — with no other code changes.

Human approvals (EU AI Act Article 14 / RBI human review)

tl.init(
    api_key="tl_live_YOUR_KEY",
    require_approval_when=lambda ctx: ctx.get("amount", 0) > 1_000_000,
    approval_message="Loan above ₹10L requires human review.",
)
result = approve_loan(application)   # pauses for sign-off on high-stakes calls

Policy packs

Pack	Region	Enforces
dpdp	India	Aadhaar / PAN / GSTIN / IFSC / Passport / card / phone / DoB blocked; consent-bypass blocked
rbi_ml_risk	India Banking	auto-approval-without-review blocked; fund-disbursal routed to approval
eu_ai_act	EU	human-oversight bypass (Art. 14) & logging suppression (Art. 12) blocked
iso42001	Global	concealing AI involvement blocked

PII patterns (17 — India + global)

Aadhaar · PAN · GSTIN (15-char) · IFSC code · Indian Passport · Driving License · Date of Birth (with context) · Visa card · Mastercard · Amex · CVV · phone · email · SSN · generic credit card · IBAN · passport (generic)

Kill switch

Pass kill_switch=True to tl.init(). When you trigger a kill from the dashboard, the next LLM/tool call raises KillSwitchTriggered in < 100 ms.

CI/CD compliance gate

trustlayer gate --pre-deploy --fail-below 80
trustlayer verify-decisions --limit 500   # tamper check in CI

---

Production reliability (v2.3.0)

Feature	Behaviour
Policy sync circuit breaker	Stops retry storms after 5 consecutive server failures; auto-resets after 5 min. Gate stays up using the last known policy.
Disk-backed decision buffer	Unflushed decisions are persisted to ~/.forma/pending_decisions.jsonl on flush failure and replayed on next startup — no audit data lost on transient outages.
HMAC-signed entries	Every buffered gate decision is signed with your API key before queuing — tamper-detectable by verify-decisions CLI or cache.verify_log().

tl.register(name, fn, **cfg) — the second entry point

Binds one existing function to a governed agent. Works as a decorator too. Accepts the same full governance argument set as init(agents={...}) per-agent config (unknown keyword → TypeError).

When to use which

Use…	When
tl.init(agents={...})	All agent functions importable at init() call. Simplest.
tl.register(name, fn, ...)	Function defined/imported after init(), decorator form, or dynamic registration.

Node.js / TypeScript

Coming soon. Runtime enforcement (enforce) and approvals are Python-only today.
