Cross-Language Plugin Contracts and SDK Parity

Full report

1. Executive Recommendation

\[Proposal\] The architectural synthesis recommends a hybrid integration model utilizing JSON-RPC 2.0 over standard I/O (stdio) or local named pipes, augmented by JSON Schema Draft 2020-12 for rigorous boundary validation. To ensure cryptographic parity and state verification across independent language environments—specifically C\# and Python—the architecture mandates the JSON Canonicalization Scheme (JCS) defined in RFC 8785 for all durable receipts. \[Protocol synthesis\] Out-of-process (OOP) isolation is required to prevent a fault in a Python or C\# plugin from destabilizing the host application. Inter-process communication (IPC) relies on a full-duplex byte stream, structured via newline-delimited JSON (NDJSON) or a length-prefixed framing specification. To mitigate memory bloat during high-throughput streaming, the protocol incorporates a credit-based flow control model1. Cancellation semantics bridge C\#'s CancellationToken and Python's asyncio.CancelledError via an out-of-band $/cancelRequest notification, drawing inspiration from the Language Server Protocol (LSP)2.

2. Scope, Assumptions, and Zero-Access Declaration

\[Assumption\] The primary operational context assumes a Windows desktop host orchestrating optional, dynamically loaded C\# and Python plugins. The host and plugins must interact through a language-neutral OOP contract to guarantee fault isolation, lifecycle independence, and equivalent capability access. \[Proposal\] The scope encompasses the design of a normative draft contract, including a common manifest, capability declarations, permission models, lifecycle state machines, settings schemas, operation envelopes, and a cryptographically verifiable receipt model. The contract is designed to evolve gracefully, permitting asynchronous updates across the host and plugin ecosystem without requiring simultaneous deployment. \[Specification\] As a strict boundary condition, this analysis operates entirely independent of any proprietary product source code, runtime behavior, internal telemetry, or existing internal manifests. All proposed namespaces, endpoints, schemas, and API signatures utilize synthetic, generic values (e.g., Acme.Host, Contoso.Plugin) to demonstrate normative concepts.

3. Source and Specification Method

\[External guidance\] The protocols and mechanisms detailed in this report synthesize established Internet Engineering Task Force (IETF) and World Wide Web Consortium (W3C) standards to prevent proprietary lock-in and minimize semantic drift. \[Specification\] Foundational specifications informing this architecture include the JavaScript Object Notation (JSON) Data Interchange Format (RFC 8259), the JSON Canonicalization Scheme (RFC 8785\)4, the Concise Binary Object Representation (CBOR) (RFC 8949\)7, and the JSON-RPC 2.0 specification8. Schema validation relies upon JSON Schema Draft 2020-129, while distributed tracing and execution correlation utilize the W3C Trace Context standard11.

4. Technology Decision Matrix

\[Analysis\] Designing a cross-language contract requires balancing schema rigor, tooling maturity, forward compatibility, streaming efficiency, and inspectability. A comparison of four dominant IPC stacks provides the necessary context for the recommended architecture.

4.1. Separating Schema, Transport, and Invocation

\[Proposal\] JSON-RPC 2.0 effectively decouples invocation from transport, allowing the same protocol to run over named pipes, standard I/O, or web sockets8. When paired with JSON Schema, it separates the data validation concern from the RPC routing concern. gRPC heavily couples the transport (HTTP/2) with the schema (Protobuf) and the invocation mechanism, introducing substantial overhead for local desktop daemons14.

4.2. Serialization Drift and Type Mapping

\[Analysis\] A critical vector for semantic drift between C\# and Python lies in JSON serialization nuances.

• Unknown Fields and Defaults: Python's json and C\#'s System.Text.Json natively ignore unknown fields during deserialization, facilitating forward compatibility. Default values must be resolved locally by the SDK, not assumed by the transport layer.
• Numeric Precision: Python seamlessly supports arbitrarily large integers. C\#'s System.Text.Json bounds integers to 64-bit boundaries unless custom converters are utilized. \[Specification\] The protocol mandates that any integer exceeding IEEE 754 double-precision exact integer bounds (-(2^53)+1 to (2^53)-1) must be transmitted as a string to prevent silent truncation.
• NaN and Infinity: JSON (RFC 8259\) explicitly forbids non-finite numbers19. Python's json.dumps non-compliantly serializes NaN and Infinity by default unless configured otherwise20. C\# strictly rejects these or maps them to strings22. \[Proposal\] SDKs must serialize non-finite floats to null or strings, and the JSON Schema must explicitly restrict non-finite values to prevent crashing the C\# host's Utf8JsonReader23.
• Timestamps: \[Specification\] To circumvent lexical variations in RFC 3339 strings (e.g., Z versus \+00:00), all timestamps must be transmitted as integer milliseconds since the Unix epoch. This ensures canonicalization safety24.
• Maps and Byte Strings: Python dictionaries preserve insertion order, whereas C\# dictionaries may not. Byte strings must be transmitted as Base64-encoded strings, as JSON lacks a native binary type.

4.3. Canonicalization Rules

\[Specification\] Cryptographic hashing of payloads requires byte-perfect alignment across languages. The JSON Canonicalization Scheme (JCS, RFC 8785\) provides the standard solution4. It mandates deterministic property sorting (lexicographical by UTF-16 code units), restricts data to the I-JSON subset (no duplicate keys), and dictates strict serialization rules for primitives, eliminating cross-language formatting disparities24.

4.4. Generated vs. Handwritten Models

\[Proposal\] Generated code ensures the SDK aligns perfectly with the JSON Schema, but tightly coupling generated Data Transfer Objects (DTOs) to domain logic creates brittleness. The architecture dictates that the JSON Schema serves as the single source of truth. DTOs are generated via tools like datamodel-code-generator (Python) or Corvus.JsonSchema (C\#)26, but developers must map these DTOs to distinct internal domain models to maintain isolation.

5. Identity and Versioning Model

\[Specification\] Ensuring rolling compatibility requires a rigid, cryptographically verifiable identity and version taxonomy.

5.1. Version and Identifier Definitions

5.2. Semantic Versioning Limitations and Handshakes

\[Analysis\] Semantic versioning falls short in decentralized plugin ecosystems because a host application upgrading its major version cannot instantly force all independent plugins to update. \[Proposal\] A capability-based handshake negotiates rolling compatibility. Upon connection, the host transmits an initialize request detailing supportedProtocolVersions: \["1.1.0", "1.2.0"\]. The plugin responds with the highest mutually supported protocol version.

5.3. Required vs. Optional Features and Sunset Policies

\[Specification\] The manifest flags capabilities as either required or optional. If a host lacks a capability marked required, the plugin aborts the handshake with an UnsupportedProtocolVersion error. If an optional capability is missing, the plugin degrades its functionality gracefully. \[Proposal\] Deprecation is managed through a documented lifecycle. Deprecated capabilities emit a diagnostic warning via a $/logMessage notification. Sunset or downgrade scenarios that breach the support matrix result in the host emitting a \-32022 UnsupportedProtocolVersion error27, forcing the plugin into a terminal Faulted state.

6. Normative Manifest Draft

\[Specification\] The manifest is a static, immutable JSON document. It is cryptographically signed and wholly isolated from mutable local configurations (settings).

6.1. Separation of Concerns and Schema Validation

\[Proposal\] The manifest defines capabilities, permissions, execution entry points, and network constraints. It employs JSON Schema Draft 2020-12, utilizing $defs for reusable components and permitting $ref sibling properties to function correctly without overriding issues prevalent in Draft 079. Schema references must be bundled within the package; remote network resolution at install time is strictly forbidden to prevent dynamic injection attacks. Localization metadata (human-readable names) resides in adjacent sidecar files to prevent signature invalidation upon translation updates.

6.2. Language-Specific Entry Points

\[Proposal\] A single manifest model supports multiple execution environments by defining mutually exclusive entry point declarations. The host platform selects the appropriate launcher.

6.3. Synthetic Manifest Example

\[Sample\] The following demonstrates a valid normative manifest structure:

JSON { "$schema": "https://json-schema.org/draft/2020-12/schema", "$id": "https://acme.com/schemas/plugin-manifest.json", "type": "object", "properties": { "identity": { "type": "object", "properties": { "pluginId": { "type": "string", "pattern": "^\[a-z0-9\\\\-\]+(\\\\.\[a-z0-9\\\\-\]+)+$" }, "publisherId": { "type": "string", "format": "uuid" }, "packageVersion": { "type": "string", "pattern": "^\\\\d+\\\\.\\\\d+\\\\.\\\\d+$" } }, "required": \["pluginId", "publisherId", "packageVersion"\] }, "entryPoint": { "type": "object", "properties": { "dotnet": { "type": "object", "properties": { "assemblyPath": { "type": "string" }, "className": { "type": "string" } }, "required": \["assemblyPath"\] }, "python": { "type": "object", "properties": { "modulePath": { "type": "string" }, "virtualEnv": { "type": "boolean" } }, "required": \["modulePath"\] } }, "minProperties": 1, "maxProperties": 1 }, "capabilities": { "type": "array", "items": { "$ref": "\#/$defs/Capability" } }, "permissions": { "type": "array", "items": { "$ref": "\#/$defs/Permission" } }, "settingsSchema": { "type": "string", "description": "URI to bundled settings schema" } }, "required": \["identity", "entryPoint", "capabilities", "permissions"\], "$defs": { "Capability": { "type": "object", "properties": { "name": { "type": "string" }, "version": { "type": "string" }, "optional": { "type": "boolean", "default": false } }, "required": \["name", "version"\] }, "Permission": { "type": "object", "properties": { "domain": { "type": "string" }, "reason": { "type": "string" } }, "required": \["domain"\] } } }

\[Analysis\] An invalid example would include arbitrary UI code inside the manifest, or attempt to resolve $schema: "http://external.site/schema.json" dynamically at runtime, violating the zero-trust execution boundary.

7. Wire Protocol and State Machines

\[Specification\] The wire protocol leverages JSON-RPC 2.0 over standard I/O (stdio) via Newline Delimited JSON (NDJSON) or named pipes via length-prefixed framing. Delivery semantics over local IPC guarantee ordered, reliable delivery, but application-level delivery (e.g., exactly-once) requires idempotency architectures14.

7.1. Invocation Semantics and Correlation

\[Protocol synthesis\]

• Request/Response Envelope: Standard JSON-RPC fields (jsonrpc, id, method, params, result, error).
• Correlation: Distributed tracing requires bridging boundaries. The params object incorporates a \_meta field adhering to the W3C Trace Context specification (traceparent, tracestate)11.
• Trace ID: Identifies the end-to-end operation spanning host and plugin.
• Span ID: Identifies the specific segment.
• Correlation ID: Binds specific asynchronous streams together.
• Idempotency Key: Allows approximation of exactly-once execution. If the plugin crashes and the host retries, the plugin inspects the Idempotency Key; if recognized, it returns the durable receipt of the prior execution rather than repeating side effects.

7.2. Flow Control, Backpressure, and Streaming

\[Analysis\] Fast producers (e.g., C\# data pipelines) can overwhelm slow consumers (e.g., Python AI models), causing buffer bloat and eventual out-of-memory (OOM) failures over bounded IPC pipes. \[Proposal\] The protocol dictates a Credit-Based Flow Control mechanism for all streams1. The receiver issues an explicit allowance via a $/credit notification. The sender consumes one credit per stream chunk emitted. When the credit counter hits zero, the sender awaits further credits, applying natural backpressure independent of the transport layer's TCP/pipe window size.

7.3. Cancellation Races

\[Analysis\] Standard JSON-RPC does not define cancellation. Implementing cancellation necessitates an out-of-band notification, mimicking the LSP $/cancelRequest2. \[Proposal\] When a host cancels an operation, it transmits {"jsonrpc": "2.0", "method": "cancelRequest", "params": {"id": 123}}. A race condition occurs if the plugin transmits the result simultaneously. The host must track the cancelled ID; if a result arrives late, the host silently accepts the terminal success and discards its own cancellation directive.

7.4. Lifecycle State Machines

\[Specification\] The execution lifecycle follows a deterministic Directed Acyclic Graph (DAG) to prevent orphaned processes and hanging threads.

8. Error, Receipt, Privacy, and Secret Model

8.1. Error Taxonomy

\[Specification\] The architecture partitions JSON-RPC error codes to facilitate programmatic routing and retry logic, strictly adhering to the JSON-RPC 2.0 reserved sub-ranges8.

8.2. Settings and User Interface Projection

\[Proposal\] Allowing plugins to execute arbitrary user interface (UI) code compromises the host's security posture. Instead, the plugin defines configuration requirements using JSON Schema, supplemented by the react-jsonschema-form (RJSF) uiSchema directives29. By defining fields such as ui:widget: "password" or ui:help, the host dynamically generates native UI controls securely.

8.3. Secrets and Privacy

\[Specification\] Manifests and configuration exports must remain strictly devoid of plaintext secrets40. \[Proposal\] Secrets are encoded as Uniform Resource Identifiers (URIs) (e.g., secret://vault/openai-key). The plugin SDK intercepts these URIs and issues a $/secrets/resolve request to the host. The host verifies the plugin's capability scope and provisions the plaintext secret directly into the plugin's volatile memory. This eliminates secrets from logs and disk-based configuration files42.

8.4. Verifiable Receipts

\[Protocol synthesis\] For auditing, billing, and repudiation defense, operations generate a receipt. To prevent leaking sensitive prompts or generated text, payload minimization is critical. Highly sensitive data classes are redacted or replaced with SHA-256 hashes. The minimized receipt is then canonicalized using JCS (RFC 8785\)6 and hashed. This creates a byte-perfect, cross-language verifiable fingerprint of the operation without transmitting bounded private data.

9. C# and Python SDK Parity

\[Analysis\] Achieving true parity requires mapping the asynchronous and typed paradigms of C\# to Python's dynamic, asyncio-driven ecosystem. The SDKs must mask the transport complexity, presenting native idioms to the developer.

9.1. Asynchronous Execution and Streaming

\[Proposal\]

• C\# Implementation: Streaming capabilities map to IAsyncEnumerable\<T\>. To minimize garbage collection (GC) overhead during high-volume IPC, the SDK utilizes System.Text.Json.Utf8JsonReader and System.IO.Pipelines. This achieves zero-allocation, forward-only stream parsing, critical for performance23. Immutable records define the DTOs.
• Python Implementation: Streaming maps to AsyncIterator\[T\]. The SDK utilizes asyncio.StreamReader and Pydantic models for strict type enforcement, emulating C\#'s immutability and schema validation.

9.2. Cancellation Parity

\[Analysis\] Cancellation models differ fundamentally between the two languages.

• C\#: Relies on cooperative cancellation via CancellationToken. Checking token.ThrowIfCancellationRequested() safely unwinds the stack via OperationCanceledException47.
• Python: asyncio.Task.cancel() injects an asyncio.CancelledError into the executing coroutine. A severe risk arises if a developer's broad except Exception: block swallows the CancelledError, resulting in a zombie task and blocking the IPC pipe49. \[Proposal\] The Python SDK's decorator must explicitly trap asyncio.CancelledError and ensure it is escalated or transformed into the \-32800 JSON-RPC error response, guaranteeing consistent behavior with the C\# implementation.

9.3. SDK Interface Sketches

\[Sample\] C\# Plugin Interface:

C\# public interface IPluginContext { CancellationToken CancellationToken { get; } ILogger Logger { get; } string Traceparent { get; } }

public interface ICapabilityHandler\<TRequest, TResponse\> { Task\<TResponse\> ExecuteAsync(TRequest request, IPluginContext context); }

public interface IStreamingHandler\<TRequest, TChunk\> { IAsyncEnumerable\<TChunk\> ExecuteStreamAsync(TRequest request, IPluginContext context); }

\[Sample\] Python Plugin Interface:

Python from typing import Protocol, TypeVar, AsyncIterator from dataclasses import dataclass import asyncio import logging

TRequest \= TypeVar('TRequest') TResponse \= TypeVar('TResponse') TChunk \= TypeVar('TChunk')

@dataclass class PluginContext: cancellation\_token: asyncio.Event logger: logging.Logger traceparent: str

class CapabilityHandler(Protocol\[TRequest, TResponse\]): async def execute(self, request: TRequest, context: PluginContext) \-\> TResponse: ...

class StreamingHandler(Protocol\[TRequest, TChunk\]): async def execute\_stream(self, request: TRequest, context: PluginContext) \-\> AsyncIterator\[TChunk\]: ...

10. Conformance and Fuzz Testing

\[Specification\] To prevent regression and ensure semantic alignment, a language-agnostic Conformance Runner executes a suite of headless behavior tests against both the C\# and Python SDKs.

10.1. Golden Serialization Vectors

\[Proposal\] The suite validates serialization parity using pre-computed "golden vectors".

1. JCS Determinism: Unordered dictionaries injected into both SDKs must emit identical UTF-8 byte streams when serialized through RFC 878524.
2. NaN Rejection: Injecting {"value": NaN} must be rejected at the SDK transport boundary with a \-32700 Parse Error before reaching domain logic54.
3. Boundary Integers: Sending 9007199254740992 (2^53) must be handled without silent rounding truncation.

10.2. Lifecycle and Transport Fuzzing

\[Proposal\] The conformance suite induces hostile environments:

• Cancellation Races: The runner issues a long-running request, sends $/cancelRequest at exactly [Figure omitted from source export] before the plugin's known completion time, and validates state machine integrity.
• Version Skew: The runner injects missing optional fields, duplicate keys, and reordered fields to verify resilient deserialization.
• Oversized Payloads: Transmitting a 50MB JSON payload to guarantee the Python asyncio buffer and C\# PipeReader handle fragmentation without out-of-memory exceptions.
• Hostile Shutdown: The runner simulates a host crash by severing the IPC pipe. The plugin SDK must detect EOF and self-terminate the process gracefully within 2000ms.

11. Contract Evolution Policy

\[Specification\] A decentralized ecosystem relies on strict evolution promises to prevent synchronization gridlock.

1. Append-Only Schemas: Existing schema properties cannot be removed or have their types mutated. New capabilities must be introduced additively.
2. Reserved Namespaces: The prefix $/ is globally reserved for protocol-level lifecycle and system instructions. Plugin-specific operations must not utilize this prefix.
3. Deprecation Windows: Deprecated capabilities (flagged via "deprecated": true in the JSON Schema)56 must be supported by the host for a minimum of two major release cycles to provide adequate migration time.
4. Emergency Revocation: If a specific plugin version demonstrates a severe security vulnerability, the host retrieves a Manifest Revocation List (MRL). Revoked plugins are actively blocked during the Handshaking phase, emitting a \-32099 PluginRevoked error.

12. Migration and Adoption Sequence

\[Analysis\] Transitioning existing in-process plugins to an out-of-process JSON-RPC architecture introduces latency and refactoring overhead. \[Proposal\] Adoption follows a phased sequence:

• Phase 1 (Proxy Generation): Generate SDK wrappers for existing in-process plugins that proxy calls through the new IPC contract internally. This identifies serialization bottlenecks and identifies payload structures unsuitable for IPC.
• Phase 2 (Dual Run): Deploy the C\# and Python OOP runners alongside the legacy system.
• Phase 3 (Enforcement): Mandate the JSON-RPC OOP capability sets for all new plugins.
• Phase 4 (Deprecation): Sun-set the in-process execution model, citing stability, strict memory isolation, and cross-language parity as the definitive architectural standard.

13. Open Implementation Questions

\[Analysis\] While the normative protocol provides a robust foundation, certain environmental edge cases require further investigation:

1. Binary Payload Optimization: Standard JSON-RPC over IPC is inefficient for transmitting massive binary blobs (e.g., machine learning tensors, large images) due to the 33% overhead of Base64 encoding. Does the architecture require an auxiliary channel (e.g., a negotiated shared memory mapped file) for high-throughput binary streaming?
2. Python Concurrency Limits: Does a single Python plugin process running a standard asyncio event loop yield sufficient throughput for concurrent host requests, or must the Python SDK implement a transparent process-pool or integration with uvloop58 to avoid Global Interpreter Lock (GIL) blocking?

14. Limitations

\[Analysis\] The proposed out-of-process plugin contract inherently introduces constraints compared to in-process execution:

1. IPC Overhead: Context switching, data copying across kernel boundaries, and JSON serialization impose latency penalties (historically \~0.5ms to \~2ms per round trip)14. This renders the architecture unsuitable for synchronous, ultra-low latency requirements, such as real-time 60 FPS UI rendering loops.
2. State Synchronization: Memory cannot be shared via pass-by-reference. All state must be serialized, transmitted, and actively synchronized, requiring careful architectural design to prevent state drift.
3. Process Management Reliability: Operating system mechanisms for terminating child processes when a parent process crashes (e.g., Windows Job Objects) can be unreliable or complex to configure securely. Orphaned plugin processes remain a persistent operational risk requiring robust watchdog timers within the SDKs.

15. Sources

\[External guidance\] The methodology and specifications utilized throughout this report derive from an extensive review of authoritative distributed systems standards. Foundational protocol structures are synthesized from the JSON-RPC 2.0 specification for remote invocation semantics and JSON Schema Draft 2020-12 for validation logic. Requirements for deterministic cross-language cryptographic signatures rely heavily on the JSON Canonicalization Scheme (RFC 8785\) to resolve systemic Python/C\# serialization disparities. Distributed tracing and correlation strategies implement the W3C Trace Context recommendation, utilizing the standardized traceparent architecture. Implementation details regarding local IPC efficiency, backpressure, and asynchronous streaming in .NET and Python environments are informed by best practices in named pipe management, System.IO.Pipelines, and asyncio event loop behaviors.
