Prepare the inputs
Create a separate workspace in Tokeny, download and unpack the sample inputs, then select a model that supports tools. The sample uses synthetic data or the public sources named in the article.
- package.json
- retry.js

The recorded run used an isolated demonstration workspace. Review the commands and file paths before approving operations in your own workspace.
What actually ran
The task was submitted through the Tokeny input box. An online model read the inputs and executed tools. This run covers the local sample task and its actual files. Results and checks are recorded below.
Results and verification
Input
I read the workspace files retry.js, package.json, and ENVIRONMENT.md. The real implementation is delay(attempt, random). It accepts a non-negative integer attempt, computes min(8000, 250*2^attempt), multiplies that value by 0.5 + random()*0.5, and rounds to an integer number of milliseconds. The package is configured as an ES module, and the environment identifies Node as the intended runtime.
Processing
First, I invoked the existing function directly with deterministic random values of 0, a value close to 1, and 1 to inspect the jitter bounds and the 8000 ms cap. I also passed a negative integer, a fractional number, a numeric string, and NaN to observe invalid-input behavior. I then created example.mjs, imported the real implementation, and supplied a fixed random sequence. The example prints a complete delay table, a jitter sample, a simulated operation that receives two HTTP 503 responses before success, and a simulated HTTP 400 response that is not retried. No network request or temporary service was used.
Actual Results
The runtime was Node v22.23.4. node example.mjs completed successfully. The output reported 125–250 ms for attempt 0, 250–500 ms for attempt 1, and 4000–8000 ms for attempt 5. Attempts 6 and 7 stayed at 4000–8000 ms, confirming that the pre-jitter value is capped at 8000 ms. Four deterministic samples at attempt 3 were 1000, 1250, 1500, and 2000 ms. The retry simulation waited 188 ms and 375 ms after status 503, then succeeded on attempt 2 with status 200. Status 400 produced retry=false. The invalid values -1, 1.5, and the string 1 each produced RangeError:attempt.
Checks
I reran node example.mjs and compared the stable output with the formula in retry.js. I checked the lower and upper jitter cases, the capped attempts, the success path, the non-retryable path, and invalid input. I also checked that all four requested files exist and that the example imports the workspace implementation rather than duplicating it.
Limitations
This is a local demonstration with synthetic inputs. It does not validate network latency, a server's Retry-After behavior, or synchronization among many real clients. Fixed random values demonstrate boundaries but do not estimate a probability distribution. The status classification is intentionally small; production code still needs an API-specific policy for timeouts, 429, 5xx, idempotent writes, maximum attempts, a total deadline, cancellation, and observability. None of those concerns should be inferred from this delay function alone.
The example also avoids sleeping, so its timing output is a calculated delay rather than elapsed wall-clock time. This makes the run fast and repeatable, but it leaves scheduler behavior, timer resolution, and cancellation timing outside the tested scope.
