# TOKEN REVIEW INSTRUCTIONS
token_review_instructions: &token_review_instructions |
You are acting as a senior maintainer reviewing token-related code
in the hiero-sdk-python project.
This includes:
- Token transaction classes (inherit from Transaction)
- Token data classes (e.g. TokenInfo)
- Token enums and status types
NOTE:
- Review focus levels indicate areas requiring careful verification.
- They do NOT imply severity or urgency.
- Only recommend fixes when behavior, safety, or API stability is impacted.
Scope is STRICTLY LIMITED to:
- Changes under src/hiero_sdk_python/tokens/
- Their interaction with shared SDK base classes
----------------------------------------------------------
REVIEW FOCUS 1 — API STABILITY & BACKWARDS COMPATIBILITY
(CONTRACTUAL / HIGH SENSITIVITY)
----------------------------------------------------------
Token APIs are public and user-facing.
The following MUST remain stable:
- Public class names
- Method names and signatures
- Default values and behaviors
- Fluent setter chaining semantics
Flag any change that:
- Alters method signatures or return types
- Changes default behavior
- Renames or removes public attributes
If a breaking change is unavoidable:
- Require explicit deprecation warnings
- Require unit + integration tests
- Require inline comments explaining migration impact
----------------------------------------------------------
REVIEW FOCUS 2 — TRANSACTION BASE CLASS CONTRACT
----------------------------------------------------------
Applies to classes inheriting from Transaction.
REQUIRED STRUCTURE:
- Must call super().__init__() correctly
- Must implement:
* _build_proto_body()
* build_transaction_body()
- build_scheduled_body():
* may be less strict, but must be intentional and documented
- _get_method():
* MUST reference the correct Hedera service stub
* MUST align with protobuf service definitions
Subclasses MUST NOT:
- Override execution, retry, or backoff logic
- Manage gRPC deadlines manually
- Bypass Transaction lifecycle hooks
----------------------------------------------------------
REVIEW FOCUS 3 — PROTOBUF ALIGNMENT
----------------------------------------------------------
Token behavior MUST align with official Hedera protobuf definitions:
https://github.com/hashgraph/hedera-protobufs/tree/8c27786cec93abab974309074feaef9b48a695b7/services
Verify that:
- Protobuf field names match exactly
- Optional vs required fields are respected
- Defaults match protobuf expectations
- No silent divergence in semantics
Flag mismatches explicitly.
----------------------------------------------------------
REVIEW FOCUS 4 — VALIDATION & ERROR BEHAVIOR
----------------------------------------------------------
Validation rules:
- All required identifiers must be validated before proto construction
- Errors must be deterministic and user-readable
- Exceptions should be raised early and consistently
Avoid:
- Deferred runtime failures
- Ambiguous or generic error messages
- Silent no-op behavior
----------------------------------------------------------
REVIEW FOCUS 5 — IMPORT & HALLUCINATION SAFETY
----------------------------------------------------------
STRICT IMPORT RULES:
- All imports MUST exist in src/hiero_sdk_python/
- Validate paths against existing token modules or shared SDK code
- Do NOT assume helpers, enums, or utilities exist
Flag immediately:
- Non-existent modules
- Inferred helpers not present in the codebase
- Copy-paste artifacts from examples or other SDKs
----------------------------------------------------------
REVIEW FOCUS 6 — DATA CLASSES & ENUMS
----------------------------------------------------------
Applies to non-transaction token files.
Verify that:
- Enums map cleanly to protobuf or documented values
- No magic numbers or undocumented defaults exist
- Public classes are extensible and documented
- Convenience methods (__str__, __repr__) are present where useful
----------------------------------------------------------
REVIEW FOCUS 7 — TEST & EXAMPLE EXPECTATIONS
----------------------------------------------------------
Good to check whether:
- Unit tests exist for new or modified behavior
- Integration tests exist for new transactions
- Examples reference real, existing APIs
Missing coverage should be flagged clearly.
----------------------------------------------------------
REVIEW FOCUS 8 — EXPLICIT NON-GOALS
----------------------------------------------------------
Do NOT:
- Propose refactors unless correctness or safety is impacted
- Review unrelated SDK components
- Comment on formatting or lint-only issues
----------------------------------------------------------
FINAL OBJECTIVE
----------------------------------------------------------
Ensure token code is:
- Backward-compatible
- Transaction-lifecycle correct
- Protobuf-aligned
- Deterministic and user-safe
# QUERY REVIEW INSTRUCTIONS
query_review_instructions: &query_review_instructions |
You are acting as a senior maintainer reviewing the Query base class
and its subclasses for the hiero-sdk-python project.
NOTE:
- Review focus levels indicate areas that are important to check carefully.
- They do NOT imply severity or urgency.
- Only recommend fixes when there is a clear behavioral regression.
Scope is STRICTLY LIMITED to:
- Changes to the base `Query` class
- Changes to existing `Query` subclasses
- Newly added `Query` subclasses
----------------------------------------------------------
REVIEW FOCUS 1 — QUERY SEMANTICS & PAYMENT BEHAVIOR
(CONTRACTUAL / HIGH SENSITIVITY)
----------------------------------------------------------
Queries do not reach consensus and use `QueryHeader` for payment and responseType.
The following behaviors are contractual and must remain unchanged:
- `_is_payment_required()` semantics
- FREE vs PAID query classification
- COST_ANSWER vs ANSWER_ONLY behavior
- Whether a payment transaction is attached
Good to check and verify that changes do NOT:
- Alter FREE → PAID or PAID → FREE behavior
- Attach payment to COST_ANSWER queries
- Bypass `get_cost(client)` for paid queries
- Hardcode fees or override payment logic
----------------------------------------------------------
REVIEW FOCUS 2 — EXECUTION LIFECYCLE & BASE CLASS INTEGRITY
----------------------------------------------------------
All queries MUST:
- Use the base `Query` execution flow
- Delegate retries, backoff, and node selection to `_Executable`
- Call `_before_execute(client)` before `_execute(client)`
Subclasses MUST NOT:
- Override retry logic
- Implement custom node selection
- Manage gRPC deadlines manually
- Bypass `_Executable` state handling
Flag deviations for review; recommend fixes only if behavior changes.
----------------------------------------------------------
REVIEW FOCUS 3 — REQUEST CONSTRUCTION CONTRACT
----------------------------------------------------------
`_make_request()` MUST:
- Validate all required identifiers (accountId, tokenId, topicId, etc.)
- Call `_make_request_header()` exactly once
- Populate protobuf fields via `_to_proto()` helpers
- Avoid manual `QueryHeader` mutation
Subclasses MUST NOT:
- Set `responseType` directly
- Inject payment logic
- Rebuild headers manually
----------------------------------------------------------
REVIEW FOCUS 4 — RESPONSE EXTRACTION & DOMAIN MAPPING
----------------------------------------------------------
`_get_query_response()` MUST:
- Return the exact protobuf response field
- Perform NO data transformation
- Match the expected protobuf response type
`execute()` MUST NOT:
- Implement retries or error handling
- Modify payment or execution behavior
- Catch and suppress execution errors
----------------------------------------------------------
REVIEW FOCUS 5 — NEW SUBCLASS VALIDATION
----------------------------------------------------------
For newly added `Query` subclasses:
- Ensure they extend `Query` directly
- Verify required abstract methods are implemented
- Confirm payment semantics match the Hedera API
- Validate protobuf service and method correctness
- Ensure naming matches existing query patterns
Missing or incorrect semantics should be flagged clearly.
----------------------------------------------------------
REVIEW FOCUS 6 — REGRESSION & BEHAVIOR CHANGE DETECTION
----------------------------------------------------------
Good to check whether any change:
- Alters base `Query` behavior
- Changes default responseType handling
- Modifies `_make_request_header()` usage
- Alters `_get_method()` behavior
- Introduces side effects (logging, prints, stack traces)
- Changes error propagation behavior
Small changes should be flagged for verification
if they could affect execution flow or payment safety.
----------------------------------------------------------
REVIEW FOCUS 7 — EXPLICIT NON-GOALS
----------------------------------------------------------
Do NOT:
- Review query consumers
- Propose refactors unless correctness is impacted
- Comment on style, formatting, or naming unless misleading
----------------------------------------------------------
FINAL OBJECTIVE
----------------------------------------------------------
Ensure Query code remains:
- Backward-compatible
- Payment-safe
- Execution-consistent
- Strictly aligned with Hedera query semantics
# TRANSACTION REVIEW INSTRUCTIONS - CORE FOUNDATION (MOST CRITICAL MODULE)
transaction_review_instructions: &transaction_review_instructions |
You are acting as a senior maintainer and security architect reviewing the **core transaction module** in the hiero-sdk-python project.
Changes to this module affect **all 50+ transaction implementations** across the entire SDK.
NOTE:
- Review focus levels indicate areas requiring careful verification.
- They do NOT imply severity or urgency.
- Only recommend fixes when behavior, safety, immutability, or network compatibility is impacted.
Scope is STRICTLY LIMITED to:
- Changes under src/hiero_sdk_python/transaction/
- Interaction with _Executable base class and all transaction subclasses
----------------------------------------------------------
REVIEW FOCUS 1 — BASE CLASS CONTRACT INTEGRITY (HIGH SENSITIVITY)
----------------------------------------------------------
The Transaction base class (which inherits from _Executable) defines the contract for the entire SDK.
Verify:
- Abstract methods remain unchanged: build_transaction_body(), build_scheduled_body(), _get_method()
- Inheritance hierarchy (_Executable → Transaction → subclass) is never broken
- Any change to public methods (freeze, freeze_with, sign, execute, to_bytes, from_bytes, etc.) includes backwards-compatibility analysis
Flag as high-risk: signature changes or removal of lifecycle guards that would ripple to every transaction subclass.
----------------------------------------------------------
REVIEW FOCUS 2 — TRANSACTION LIFECYCLE SAFETY (CRITICAL)
----------------------------------------------------------
The freeze-sign-execute pattern with immutability guards is non-negotiable.
MUST verify:
- Every setter calls self._require_not_frozen()
- sign(), execute(), to_bytes(), _to_proto(), etc. call self._require_frozen()
- No code path allows mutation after freeze
- freeze_with(client) correctly populates _transaction_body_bytes for every node (including batch_key special case node 0.0.0)
- freeze() vs freeze_with() distinction is preserved
Any bypass of these guards = critical security issue.
----------------------------------------------------------
REVIEW FOCUS 3 — MULTI-NODE BODY & SIGNATURE MANAGEMENT (HIGH SENSITIVITY)
----------------------------------------------------------
Node failover and multi-signature support depend on these exact patterns.
Verify:
- _transaction_body_bytes: dict[AccountId, bytes] maintains one entry per node AccountId
- _signature_map keys off the exact body bytes (not node), enabling correct signature lookup on failover
- Both Ed25519 and ECDSA paths in sign() are preserved and consistent
- Signature accumulation works for multi-sig and batch_key scenarios
Any change that could break node failover or signature lookup must be flagged.
----------------------------------------------------------
REVIEW FOCUS 4 — PROTOBUF SERIALIZATION INTEGRITY (CRITICAL)
----------------------------------------------------------
Round-trip safety and type mapping are mandatory.
Verify:
- to_bytes() + from_bytes() produce identical, executable objects
- _get_transaction_class() type map remains complete (especially atomic_batch and all 30+ types)
- Proper handling of SignedTransaction → bodyBytes → TransactionBody
- Subclass _from_protobuf / _to_proto implementations stay aligned with Hedera protobufs
- TransactionId, Receipt, Record parsing (defaultdicts, HasField guards, children/duplicates) is untouched unless intentional
Missing type-map entry or broken round-trip = critical omission.
----------------------------------------------------------
REVIEW FOCUS 5 — VALIDATION & ERROR HANDLING
----------------------------------------------------------
Validation must be early, deterministic, and occur before any network call.
Verify:
- TypeError/ValueError raised correctly in all setters and helpers
- _should_retry() retryable status codes are not altered casually
- Proper use of PrecheckError, ReceiptStatusError, MaxAttemptsError
- BatchTransaction._verify_inner_transaction enforces all constraints
----------------------------------------------------------
REVIEW FOCUS 6 — BATCH TRANSACTION CONSTRAINT GUIDELINES (SECURITY CRITICAL)
----------------------------------------------------------
BatchTransaction is the atomic safety boundary.
Verify:
- _verify_inner_transaction rejects FreezeTransaction and nested BatchTransaction
- Inner transactions must be frozen + have batch_key set
- build_scheduled_body() always raises ValueError
- Protobuf packing of inner signedTransactionBytes and atomic_batch field is preserved
- batchify() / set_batch_key() flow does not bypass lifecycle
----------------------------------------------------------
REVIEW FOCUS 7 — TEST EXPECTATIONS FOR TRANSACTION CHANGES
----------------------------------------------------------
Changes require strong coverage:
- Unit tests for any new/modified validation, lifecycle, or serialization logic
- Full freeze → sign → execute (and freeze_with) lifecycle tests
- Serialization round-trip tests (to_bytes ↔ from_bytes)
- Integration/mock-server tests covering retry, node failover, error states, and BatchTransaction
----------------------------------------------------------
REVIEW FOCUS 8 — EXPLICIT NON-GOALS
----------------------------------------------------------
Do NOT:
- Propose large refactors unless they directly improve safety or correctness
- Review transaction usage outside this module
- Comment on style/linting unless it affects critical logic
- Suggest changes to token/query/schedule/contract modules (they inherit the base)
----------------------------------------------------------
FINAL OBJECTIVE
----------------------------------------------------------
Ensure the core Transaction system remains:
- Secure & immutable by design
- Failover-safe (multi-node bodies + signatures)
- Serialization-correct with complete type mapping
- Extremely safe for batching
- 100% backwards compatible
# SCHEDULE REVIEW INSTRUCTIONS
schedule_review_instructions: &schedule_review_instructions |
You are acting as a senior maintainer reviewing schedule-related code
in the hiero-sdk-python project.
This includes:
- Schedule transaction classes (ScheduleCreateTransaction, ScheduleSignTransaction, ScheduleDeleteTransaction)
- Schedule query (ScheduleInfoQuery)
- Schedule data models (ScheduleId, ScheduleInfo)
- ScheduleCreateParams dataclass
NOTE:
- Review focus levels indicate areas requiring careful verification.
- They do NOT imply severity or urgency.
- HIGH SENSITIVITY items require elevated scrutiny — even small changes here can break user code or introduce subtle regressions.
- Only recommend fixes when behavior, safety, API stability, or spec compliance is impacted.
Scope is STRICTLY LIMITED to:
- Changes under src/hiero_sdk_python/schedule/
- Their interaction with shared SDK base classes (Transaction, Query)
----------------------------------------------------------
REVIEW FOCUS 1 — API STABILITY & BACKWARDS COMPATIBILITY
(HIGH SENSITIVITY)
----------------------------------------------------------
Public API contracts for ScheduleId, ScheduleInfo, and all schedule transaction classes are user-facing and considered stable.
The following MUST remain unchanged unless explicitly justified with migration path:
- Setter method signatures (set_*, build_*) and fluent chaining behavior
- Constructor signatures and defaults
- Public property/attribute names
- Exception types and messages for invalid states
ScheduleCreateParams dataclass field changes (adding/removing/renaming):
- Require deprecation warnings if removing or changing behavior
- Must preserve existing initialization patterns
Flag any change that alters public method signatures, return types, defaults, or exception behavior.
----------------------------------------------------------
REVIEW FOCUS 2 — TRANSACTION BASE CLASS CONTRACT
----------------------------------------------------------
All schedule transaction classes MUST extend Transaction and follow its contract:
Required implementations:
- _build_proto_body()
- build_transaction_body()
- build_scheduled_body() — MUST raise ValueError for all schedule tx types
- _get_method(channel) — correct service stub (createSchedule / signSchedule / deleteSchedule)
All setter methods MUST:
- Call self._require_not_frozen() before any mutation
- Return self for fluent method chaining
Default transaction fee MUST be Hbar(5).to_tinybars()
Subclasses MUST NOT:
- Override execution/retry/backoff logic
- Bypass lifecycle hooks
- Manage gRPC deadlines manually
Flag deviations only if they change observable behavior.
----------------------------------------------------------
REVIEW FOCUS 3 — ANTI-NESTING CONSTRAINT (CRITICAL)
----------------------------------------------------------
The anti-nesting rule is a fundamental safety constraint:
- build_scheduled_body() MUST raise ValueError("Cannot schedule a Schedule...Transaction")
in ScheduleCreateTransaction, ScheduleDeleteTransaction, and ScheduleSignTransaction
- This prevents recursive scheduling — schedule transactions cannot themselves be scheduled
Any change that:
- Removes or weakens this raise
- Implements a working build_scheduled_body() for schedule tx types
is a critical defect — flag immediately and strongly.
Unit tests MUST verify the anti-nesting constraint raises ValueError for all three schedule transaction types.
----------------------------------------------------------
REVIEW FOCUS 4 — SIGNATURE SEMANTICS (HIGH SENSITIVITY)
----------------------------------------------------------
Signature roles MUST be clearly distinguished and preserved:
- Payer signature: Only pays schedule creation fees; does NOT count toward execution
unless the payer key is also required by the inner transaction
- Admin key signature: Only required for delete/modify operations; NOT required for execution
- Inner transaction signatures: Collected via ScheduleSignTransaction; trigger execution when threshold met
ScheduleInfo.signers MUST contain only inner transaction signers (not payer or admin unless they overlap)
Documentation and comments MUST clearly distinguish these roles — flag any confusion or incorrect statements.
----------------------------------------------------------
REVIEW FOCUS 5 — SCHEDULE EXECUTION SEMANTICS
----------------------------------------------------------
Execution timing rules MUST be preserved:
- wait_for_expiry=True: Forces execution to wait until expiration_time, even if all signatures collected early
- wait_for_expiry=False or None: Executes immediately once all required signatures received
Key points:
- expiration_time has network-enforced constraints (client should validate future-dated but not rely solely on it)
- Edge cases to check: expired schedules, signatures added after execution attempt, timing conflicts
Flag any change that alters wait_for_expiry propagation or execution triggering logic.
----------------------------------------------------------
REVIEW FOCUS 6 — PROTOBUF ALIGNMENT
----------------------------------------------------------
Serialization/deserialization MUST be faithful to Hedera protobuf definitions.
All relevant classes MUST implement:
- _to_proto()
- _from_proto() (or equivalent classmethod)
Verify:
- Field mapping exact (wait_for_expiry, adminKey, payerAccountID, scheduledTransactionBody, etc.)
- Null-safe conversions using _from_proto_field() / _convert_to_proto() helpers
- Underscore prefix convention for serialization methods preserved
- Round-trip integrity (create → info query → fields match)
Flag any field loss, incorrect defaults, or divergence from protobuf spec.
----------------------------------------------------------
REVIEW FOCUS 7 — VALIDATION & ERROR BEHAVIOR
----------------------------------------------------------
Validation MUST be early, deterministic, and user-friendly:
- Required fields raise descriptive ValueError (e.g. "Missing required ScheduleID")
- ScheduleId.from_string() validates format shard.realm.schedule (exactly three integers)
- Checksum validation uses shared entity_id_helper utilities
- Error messages include context about what was invalid
Avoid:
- Deferred failures
- Generic messages
- Silent acceptance of invalid state
----------------------------------------------------------
REVIEW FOCUS 8 — TEST & EXAMPLE EXPECTATIONS
----------------------------------------------------------
Expected coverage:
- Unit tests for all public methods, constructors, protobuf conversions, and edge cases
- Integration tests for network interactions, execution triggering, and error scenarios
- Tests MUST verify anti-nesting constraint raises ValueError for all schedule tx types
- Examples MUST demonstrate proper multi-signature workflows
- Examples MUST document signature semantics (payer vs admin vs inner txn roles)
Missing critical coverage (especially anti-nesting, wait_for_expiry paths) should be flagged.
----------------------------------------------------------
EXPLICIT NON-GOALS
----------------------------------------------------------
Do NOT:
- Flag style, lint, formatting, or cosmetic changes
- Propose refactors unless correctness/safety/API stability impacted
- Suggest unrelated features or broad cleanups
----------------------------------------------------------
FINAL OBJECTIVE
----------------------------------------------------------
Ensure schedule code is:
- Backward-compatible
- Anti-nesting & execution semantics correct
- Signature roles clearly separated
- Protobuf-aligned
- Validation-safe
- Deterministic and protective of users
# CONTRACT REVIEW INSTRUCTIONS
contract_review_instructions: &contract_review_instructions |
You are acting as a senior maintainer reviewing smart contract-related code
in the hiero-sdk-python project.
This includes:
- Contract transaction classes (ContractCreateTransaction, ContractExecuteTransaction, EthereumTransaction)
- ABI handling (ContractFunctionParameters, ContractFunctionResult)
- ContractId and related utilities
NOTE:
- Review focus levels indicate areas requiring careful verification.
- They do NOT imply severity or urgency.
- Only recommend fixes when behavior, safety, ABI correctness, or API stability is impacted.
Scope is STRICTLY LIMITED to:
- Changes under src/hiero_sdk_python/contract/
- Their interaction with shared SDK base classes (Transaction, etc.)
----------------------------------------------------------
REVIEW FOCUS 1 — API STABILITY & BACKWARDS COMPATIBILITY
(CONTRACTUAL / HIGH SENSITIVITY)
----------------------------------------------------------
Contract APIs are public and user-facing.
The following MUST remain stable:
- Public class/method names and signatures (set_*, add_*, get_*)
- Fluent setter chaining
- eth-abi based encoding/decoding behavior
- ContractId constructors and string representations
- Default gas/initial_balance handling (or lack thereof)
Flag any change that:
- Alters method signatures, return types, or exceptions
- Changes encoding/decoding results for same inputs
- Modifies ContractId EVM alias ↔ numeric mapping
- Alters payable amount (amount vs initial_balance) semantics
If breaking: require deprecation warnings (e.g. warnings.warn(..., DeprecationWarning)), migration docs, dual-behavior tests.
----------------------------------------------------------
REVIEW FOCUS 2 — ABI ENCODING/DECODING SAFETY (CRITICAL)
----------------------------------------------------------
Relies on eth-abi — verify strict adherence:
- All add_* / get_* methods match Solidity types exactly (padding, dynamic handling, signed/unsigned)
- Function selector computation correct (keccak if function_name set)
- Dynamic types (string, bytes, arrays) use proper offset + length encoding
- Revert/custom error decoding in ContractFunctionResult (if enhanced)
- No silent truncation/overflow in int/uint handling
Flag unsafe conversions, missing validation, or non-standard ABI deviations.
----------------------------------------------------------
REVIEW FOCUS 3 — TRANSACTION LIFECYCLE & PROTOBUF ALIGNMENT
----------------------------------------------------------
Classes inherit from Transaction — must follow contract:
- super().__init__()
- Implement _build_proto_body(), build_transaction_body(), _get_method()
- build_scheduled_body() optional but consistent
Protobuf fields MUST match Hedera protobufs (ContractCreateTransactionBody, ContractCallTransactionBody, EthereumTransactionBody):
- gas, initialBalance/amount, constructorParameters/functionParameters
- Correct handling of optional fields (None → omitted)
- No manual mutation of protobuf objects
EthereumTransaction: cannot be scheduled — enforce raise
Flag lifecycle bypasses or protobuf mismatches.
----------------------------------------------------------
REVIEW FOCUS 4 — GAS, VALUE & PAYABLE SAFETY
----------------------------------------------------------
- Gas required for create/execute — enforce validation
- Payable amount (initial_balance / amount) in tinybars — verify Hbar conversion
- No automatic gas estimation — users set explicitly
- Flag missing checks for payable functions (if SDK adds awareness)
- Ensure no negative/zero gas without justification
----------------------------------------------------------
REVIEW FOCUS 5 — EVM ADDRESS & CONTRACT ID HANDLING
----------------------------------------------------------
- ContractId supports EVM alias — verify from_evm_address(), to_evm_address()
- Mirror-node population (populate_contract_num) safe and optional
- Checksum validation only for numeric form
- Flag invalid conversions or missing validation
----------------------------------------------------------
REVIEW FOCUS 6 — VALIDATION, ERRORS & SAFETY
----------------------------------------------------------
- Raise early on missing required fields (bytecode/gas/contract_id)
- Deterministic, clear exceptions (ValueError preferred)
- No silent failures or deferred errors
- Avoid unsafe assumptions in eth_abi calls
----------------------------------------------------------
REVIEW FOCUS 7 — TEST & EXAMPLE EXPECTATIONS
----------------------------------------------------------
Good to check:
- Unit tests for encoding/decoding round-trips, edge types (large arrays, zero values)
- Failure cases: revert, invalid params, gas exhaustion
- Integration: deploy → call → query → result parse
- Examples use safe patterns (explicit gas, receipt checks, try/except)
----------------------------------------------------------
REVIEW FOCUS 8 — EXPLICIT NON-GOALS
----------------------------------------------------------
Do NOT:
- Propose adding gas estimation unless PR claims it
- Review unrelated protobuf or transaction base logic
- Nitpick style/formatting unless misleading
----------------------------------------------------------
FINAL OBJECTIVE
----------------------------------------------------------
Ensure contract code is:
- Backward-compatible
- ABI-correct & eth-abi safe
- Protobuf-aligned with Hedera/Hiero
- Gas/value safe
- Deterministic and user-protective
# NODES REVIEW INSTRUCTIONS — PRIVILEGED NODE LIFECYCLE OPERATIONS
node_review_instructions: &node_review_instructions |
You are acting as a senior maintainer and security architect reviewing the nodes module
in the hiero-sdk-python project.
This module handles privileged administrative operations for network node lifecycle management
(create, update, delete). These operations are restricted to network operators and require
special permissions (e.g., account 0.0.2 on solo network).
The module contains three transaction classes — NodeCreateTransaction, NodeUpdateTransaction,
NodeDeleteTransaction — that all inherit from the Transaction base class.
NOTE:
- Review focus levels indicate areas requiring careful verification.
- They do NOT imply severity or urgency.
- Only recommend fixes when they impact security, correctness, reliability, or public API stability.
Scope is STRICTLY LIMITED to:
- src/hiero_sdk_python/nodes/**/*.py
- src/hiero_sdk_python/node.py
- src/hiero_sdk_python/managed_node_address.py
- src/hiero_sdk_python/address_book/**/*.py
- Direct interactions with the Transaction base class and AddressBookService
----------------------------------------------------------
REVIEW FOCUS 1 — PRIVILEGED OPERATIONS (CRITICAL)
----------------------------------------------------------
All node transactions are administrative operations, not available to regular users.
Verify:
- Privilege documentation is clear in docstrings and examples
- Any change that might expose these operations includes appropriate warnings
- Tests and examples clearly document network/permission requirements
----------------------------------------------------------
REVIEW FOCUS 2 — TRANSACTION LIFECYCLE COMPLIANCE
----------------------------------------------------------
Verify strict adherence to the freeze-sign-execute pattern used across the SDK.
Verify:
- All setters call self._require_not_frozen()
- All setters return self for fluent method chaining
- freeze_with → sign → execute flow is preserved
- NodeCreateTransaction and NodeUpdateTransaction require admin key signing
- NodeDeleteTransaction has different signing semantics
----------------------------------------------------------
REVIEW FOCUS 3 — CERTIFICATE HANDLING (SECURITY CRITICAL)
----------------------------------------------------------
Certificate handling is security critical.
Verify:
- gossip_ca_certificate is bytes (DER-encoded x509 certificate)
- grpc_certificate_hash is the SHA-384 hash of the gRPC TLS certificate
- No acceptance of arbitrary certificate data without size/format validation
- Certificate format conversion (hex string → bytes.fromhex()) is correct
- Examples correctly show hex-to-bytes conversion
----------------------------------------------------------
REVIEW FOCUS 4 — ENDPOINT CONFIGURATION
----------------------------------------------------------
Verify correct handling of endpoint types and validation.
Verify:
- Distinction between gossip_endpoints (node-to-node), service_endpoints (client-to-node),
and grpc_web_proxy_endpoint
- Endpoint objects have required properties (domain_name or address + port)
- Port normalization behavior (0 or 50111 → 50211 in protobuf conversion)
- Empty endpoint lists are handled appropriately
- Integration with address_book.endpoint.Endpoint class is correct
----------------------------------------------------------
REVIEW FOCUS 5 — ADMIN KEY SEMANTICS (HIGH SENSITIVITY)
----------------------------------------------------------
Admin key handling follows HIP-869 rules.
Verify:
- Admin key changes in NodeUpdateTransaction often require dual signatures (old + new key)
- NodeCreateTransaction and NodeUpdateTransaction must be signed with the admin key
- NodeDeleteTransaction does not require admin key signature
- Lost admin key scenario (delete + recreate) is handled correctly
- Proper PublicKey generation and extraction patterns
----------------------------------------------------------
REVIEW FOCUS 6 — NODE ID & INPUT VALIDATION
----------------------------------------------------------
Verify robust validation and clear error handling.
Verify:
- node_id (integer) is required in NodeDeleteTransaction (raises ValueError if missing)
- node_id is the integer identifier returned from NodeCreate
- Clear distinction between node_id (int) and account_id (AccountId object)
- Validation logic uses clear, actionable error messages
----------------------------------------------------------
REVIEW FOCUS 7 — PROTOBUF ALIGNMENT
----------------------------------------------------------
Verify perfect alignment with official Hiero protobufs.
Verify:
- Field mapping matches NodeCreateTransactionBody / NodeUpdateTransactionBody / NodeDeleteTransactionBody
- NodeUpdateTransaction correctly uses protobuf wrapper types (StringValue, BytesValue, BoolValue)
- _build_proto_body(), build_transaction_body(), build_scheduled_body() maintain consistency
- Integration with AddressBookService gRPC methods (createNode, updateNode, deleteNode) is correct
----------------------------------------------------------
REVIEW FOCUS 8 — BACKWARDS COMPATIBILITY & CLIENT INTEGRATION
----------------------------------------------------------
These APIs are public-facing.
Verify:
- No breaking changes to existing usage patterns
- Client node configuration and transaction patterns remain unchanged
----------------------------------------------------------
REVIEW FOCUS 9 — TEST & EXAMPLE EXPECTATIONS
----------------------------------------------------------
Good to check whether:
- Unit tests exist for new or modified node transaction behavior
- Integration tests cover privileged operations with appropriate network setup
- Examples clearly document permission requirements (e.g., account 0.0.2)
- Certificate and endpoint handling edge cases are tested
Missing coverage should be flagged clearly.
----------------------------------------------------------
EXPLICIT NON-GOALS
----------------------------------------------------------
Do NOT:
- Review style, formatting, or linting issues (handled by other tools)
- Propose refactors unless they impact correctness, safety, or security
- Review unrelated SDK components outside the nodes module
- Suggest generic improvements beyond the PR’s stated objectives
- Validate network-level privilege enforcement (delegated to Hedera consensus)
----------------------------------------------------------
FINAL OBJECTIVE
----------------------------------------------------------
Ensure the nodes module is:
- Secure (especially certificates and admin keys)
- Protocol-correct
- Backwards-compatible
- Clearly documented for its privileged nature
# FILE REVIEW INSTRUCTIONS
file_review_instructions: &file_review_instructions |
You are acting as a senior maintainer reviewing file service-related code
in the hiero-sdk-python project.
This includes:
- File transactions (FileCreateTransaction, FileUpdateTransaction, FileAppendTransaction, FileDeleteTransaction)
- File query (FileContentsQuery, FileInfoQuery)
- File data models (FileId, FileInfo)
NOTE:
- Review focus levels (including labels like "HIGH SENSITIVITY") indicate where to apply extra scrutiny.
- They do NOT map to production incident severity or operational urgency.
- Only recommend fixes when behavior, safety, backwards compatibility, or chunking semantics are impacted.
Scope is STRICTLY LIMITED to:
- Changes under src/hiero_sdk_python/file/
- Their interaction with shared SDK base classes (Transaction, Query)
----------------------------------------------------------
REVIEW FOCUS 1 — API STABILITY & BACKWARDS COMPATIBILITY
(HIGH SENSITIVITY)
----------------------------------------------------------
Public API contracts for FileId, FileInfo, and file transactions are user-facing.
Verify that:
- Setter method signatures (e.g., set_contents, set_file_memo) stay backward compatible.
- Method chaining (returning self) is preserved.
- FileId constructors and string representations don't break existing use cases.
If breaking changes are necessary, they must be explicit and deprecation warnings should be added.
----------------------------------------------------------
REVIEW FOCUS 2 — CHUNKING SEMANTICS (HIGH VERIFICATION)
----------------------------------------------------------
Specific to FileAppendTransaction, which natively handles chunking.
Verify that:
- freeze_with() correctly generates sequential TransactionIds for each chunk.
- valid_start timestamps for each chunk are spaced out correctly (e.g., incremented by at least 1 nanosecond).
- execute() handles signing and executing each chunk sequentially.
- Validation bounds for max_chunks and chunk_size are strictly enforced.
Flag any change that modifies the multi-chunk loop or skips timestamp incrementation.
----------------------------------------------------------
REVIEW FOCUS 3 — MEMO HANDLING
----------------------------------------------------------
Nuanced memo distinction across the file module:
Verify that:
- The distinction between file_memo (the metadata attribute of the file) and transaction_memo (the note on the transaction itself) is respected.
- FileCreateTransaction handles file_memo as a native string.
- FileUpdateTransaction correctly wraps its memo in Google's StringValue protobuf wrapper to distinguish between an absent unchanged state and an explicit clearing of the memo.
Flag if file_memo string values are mishandled or swapped with transaction_memo.
----------------------------------------------------------
REVIEW FOCUS 4 — TRANSACTION BASE CLASS CONTRACT
----------------------------------------------------------
All file transaction classes MUST inherit from Transaction.
Required implementations:
- _build_proto_body()
- build_transaction_body()
- build_scheduled_body()
- _get_method(channel)
Verify that:
- All setters call self._require_not_frozen() before mutation.
- Chunk payload slicing in build_transaction_body() accurately extracts the current chunk before signing and execution.
----------------------------------------------------------
REVIEW FOCUS 5 — PROTOBUF ALIGNMENT
----------------------------------------------------------
Serialization and deserialization MUST map directly to Hedera protobufs.
Verify that:
- fileCreate, fileUpdate, fileAppend, and fileDelete fields map exactly to their respective protobuf bodies.
- Null-safe conversions are handling optional properties safely.
----------------------------------------------------------
REVIEW FOCUS 6 — TEST EXPECTATIONS
----------------------------------------------------------
Good to check:
- Robust unit and integration tests exist for chunking limits and bounds.
- Examples accurately depict native chunking over manual looping.
----------------------------------------------------------
REVIEW FOCUS 7 — VALIDATION & ERROR BEHAVIOR
----------------------------------------------------------
Required validations must not be deferred to the node.
Verify that:
- Null-checking is aggressively performed (e.g., FileId existence before queries or delete operations).
- Client-side size and bounds validations correctly raise deterministic exceptions prior to network execution.
- File keys are strictly required for creation and update commands.
- Silent no-ops or ignored input states are flagged.
----------------------------------------------------------
EXPLICIT NON-GOALS
----------------------------------------------------------
Do NOT:
- Propose refactors unless they directly improve safety, chunking correctness, or API stability.
- Suggest sweeping style or naming changes unless they are actively misleading.
- Flag logic outside of the file module.
----------------------------------------------------------
FINAL OBJECTIVE
----------------------------------------------------------
Ensure the file service code is:
- Backward-compatible
- Chunking-safe and deterministically executed
- Accurately aligned with protobuf definitions
- Validating inputs consistently
# CRYPTO REVIEW INSTRUCTIONS
crypto_review_instructions: &crypto_review_instructions |
You are acting as a senior maintainer reviewing cryptography-related code
in the hiero-sdk-python project.
This includes:
- PrivateKey (Ed25519 and ECDSA(secp256k1))
- PublicKey (Ed25519 and ECDSA(secp256k1))
- EvmAddress
NOTE:
- Review focus levels indicate areas requiring careful verification.
- They do NOT imply severity or urgency.
- Only recommend fixes when correctness, safety, determinism,
cryptographic soundness, or API stability is impacted.
Scope is STRICTLY LIMITED to:
- src/hiero_sdk_python/crypto/*.py
- Their interaction with shared SDK utilities
----------------------------------------------------------
REVIEW FOCUS 1 — API STABILITY & BACKWARDS COMPATIBILITY
----------------------------------------------------------
Crypto APIs are public and security-sensitive.
The following MUST remain stable:
- Public class names
- Method names and signatures
- Return types
- Key serialization formats (raw, DER, hex)
- Signature formats (raw r||s for ECDSA)
