## Understanding Default Retry Parameters

Configuring retry logic within the TryInterlock SDK requires a precise understanding of its default exponential backoff mechanism, which automatically activates when transient network failures or service unavailability errors occur during agent execution. By default, the system applies a base delay of one second, doubling the wait time with each subsequent attempt to prevent overwhelming downstream services. This approach ensures that your multi-agent workflows remain resilient against temporary infrastructure hiccups without requiring manual intervention for every minor disruption. Developers can override these defaults by injecting custom configuration objects into the workflow definition, allowing for fine-tuned control over maximum attempts and initial delay intervals.

To implement this customization, you must instantiate the retry policy class provided by the SDK and pass it explicitly during the agent initialization phase. This process involves defining specific thresholds for acceptable error codes and setting a cap on total retries to avoid infinite loops in production environments. It is crucial to ensure that your custom parameters align with the overall timeout constraints of your orchestration layer, as mismatched values can lead to premature workflow termination or excessive resource consumption. Carefully balancing these settings guarantees that your interlocking agents maintain stability while efficiently recovering from intermittent failures, ultimately enhancing the reliability of your automated decision-making processes across complex operational scenarios.

## Configuring Exponential Backoff Strategies

In the tryinterlock SDK, retry behavior is configured through a RetryPolicy attached to each workflow step or agent invocation, rather than through global environment variables or hidden defaults. A policy accepts maxAttempts, baseDelay, multiplier, jitter, and timeout values, and it can be overridden per agent when one service is less reliable than another. This keeps retry decisions close to the operation that needs them and makes failures easier to reason about.

When a step fails, the runtime evaluates the policy, waits for the computed delay, and retries only idempotent actions unless the developer explicitly marks an operation as safe to repeat. Backoff caps prevent runaway waits, while telemetry records each attempt so teams can tune thresholds without changing business logic. Defaults remain conservative, but production workflows usually define explicit, carefully tuned policies for external calls, shared agents, and cross-network dependencies.

## Setting Maximum Retry Attempt Limits

When defining a workflow or initializing an agent client, you can cap retry attempts by setting the maxAttempts property within the retry configuration object. For example, passing retry: { maxAttempts: 3 } to a task definition ensures a failing operation—such as an external API call or an agent handoff—is attempted no more than three times before the SDK stops. This limit applies per invocation, so each step in an interlocked workflow maintains its own counter. Setting the value to zero disables retries entirely, while omitting it falls back to the platform’s default ceiling.

Once the maximum is reached, the SDK surfaces a terminal RetryLimitExceeded error and marks the task as failed. In a multi-agent workflow, this failure can trigger a configured fallback path or halt the dependent chain, preventing cascading loops between agents. The error’s metadata includes the attempt count and the last underlying exception, helping you distinguish transient issues from persistent faults. Adjusting this limit lets you balance resilience against latency and cost in orchestrated pipelines.

## Handling Specific Error Code Responses

In the TryInterlock SDK, retry logic is configured through the client constructor options, where you set maximum attempts, base delay, exponential backoff, and jitter. These defaults apply to every request, but individual calls can override them by passing a retry policy object. The SDK treats 429 and 5xx responses as retryable, while 4xx client errors fail immediately unless you explicitly mark them retryable in the policy. This keeps transient infrastructure failures from aborting multi-agent workflows across all distributed services.

To avoid duplicate side effects, retries should be paired with idempotency keys for mutating workflow actions. When a retry succeeds after a timeout, the platform uses the key to return the original result instead of creating another task. This makes retry configuration safe for agent orchestration, especially when interlocking steps depend on prior outputs and partial failures must not duplicate work.

## Monitoring Retry Logs and Metrics

Once your retry configuration is live, the SDK emits structured log events for every retry attempt, including the original error class, the delay applied, and the attempt number. Enable verbose logging during development by setting the logLevel option to "debug" when initializing the client, then watch for retry.scheduled and retry.exhausted events in your output. In production, these events can be piped into your observability stack through the SDK's webhook support or shipped via your existing log collector. The platform dashboard also aggregates retry statistics per workflow node, showing failure rates and average recovery times, which helps identify agents that consistently need more attempts than your policy allows.

To wire this into monitoring tools, attach the onRetry callback to your client configuration and forward each event to your metrics system as a counter or histogram. Tag events with the agent name and operation type so you can slice the data later. If a particular interlock step exceeds its retry budget repeatedly, alert on the exhausted-retry metric rather than individual failures, since that signals a genuine fault rather than transient noise.

## Retry Configuration Options

| Option | Default | Description |
| --- | --- | --- |
| maxRetries | 3 | Sets the maximum number of retry attempts for a failed agent call or workflow step. |
| retryDelayMs | 1000 | Defines the initial wait time in milliseconds before the first retry is attempted. |
| backoffStrategy | exponential | Controls how delay increases between retries (fixed, linear, or exponential). |
| retryOn | ["timeout","5xx"] | Specifies which error types or status codes should trigger an automatic retry. |

In the TryInterlock SDK, retry logic is configured when initializing the client or defining a workflow step by passing a retry object with the desired options. This allows teams to tune resilience for transient failures, such as network timeouts or temporary service errors, while keeping agent orchestration predictable. Combining backoff strategies with targeted error matching helps balance reliability and execution cost.

## Quick answers

### Can I disable retries for specific agents?

Yes, you can override global settings by setting the retry_enabled flag to false in the agent's specific config block.

### What happens if the network timeout occurs?

The SDK automatically triggers a retry sequence based on the configured backoff strategy unless a hard failure is defined.

### How do I log failed retry attempts?

Enable verbose logging in your SDK instance to capture detailed error stacks and timestamps for each retry cycle.

### Is there a limit to retry duration?

You can set a total timeout duration that stops all retries if the cumulative time exceeds your specified threshold.
