This second goto fail is unconditional. With no braces on the if, it always jumps, so the signature check below never runs.

GPT-5.2 Agreement OpenRouter API

Confirmed. Everything past SSLHashSHA1.final is dead code, so the certificate is accepted without ever being verified.

This is CVE-2014-1266. While deleting the duplicate line fixes the bug, the real lesson is that omitting braces on if blocks is a trap. We should enforce mandatory braces in our linter to eliminate this entire class of indentation errors.

Fits with your local development loop

Diff your changes, self-review and then kick off a multi-model AI-assisted review to find issues that you missed. Copy feedback as markdown back in to your coding agent.

Multi-model reviews

Pit models against each other. Choose the models you want to review with, and whether to run sequentially or in parallel. When run sequentially, each model receives the previous feedback as input.
Interactive Self-Review

Look over your diffs and add your own notes locally. Copy your own feedback as markdown to send back to your coding agent to iterate on the code.
Local and native

Coducky runs locally as a native macOS application. Your diffs and reviews are stored locally on your Mac. Your code is reviewed directly via provider's APIs, MCP, or ACP.

Launch a review from your agent with MCP.

Your coding agent can hand your working tree to Coducky over MCP, pick the reviewers, and stream findings into the native diff view.

Y You Explain

Does `tryPromise` still get interrupted when the caller cancels this Effect during a retry delay?

flash 3.5 Warning

Yes, but only because this uses the `signal` argument from `tryPromise`. Passing it into `fetch` lets Effect interrupt the in-flight request instead of waiting for the promise to settle.

gpt-5.4-mini Agrees

The retry schedule is also interruptible. A fiber interruption during the delay stops the next attempt from starting.

93 + try: (signal) => fetch(url, { signal }),

94 + catch: (cause) => new FetchError(cause)

95 + })

96 + .pipe(Effect.flatMap((response) => response.json()))

97 + .pipe(Effect.retry(retryPolicy))

gpt-5.4-mini Warning

This retry wraps JSON parsing too, because it is applied after `flatMap`. Move `Effect.retry(retryPolicy)` before decoding if only the network request should be retried.

99 + const retryPolicy = Schedule.addDelay(

100 + Schedule.recurs(2),
