Rate limit exceeded

@0xddong has exceeded the limit for the number of commits or files that can be reviewed per hour. Please wait 20 minutes and 25 seconds before requesting another review.

How to resolve this issue?

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

We recommend that you space out your commits to avoid hitting the rate limit.

How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Walkthrough

The changes involve modifications to the Strategy contract and the TestUSDCSellRepoToken contract. The simulateLiquidity function has been updated to include a new output parameter, simulatedRepoTokenConcentrationRatio, and its logic adjusted accordingly. Additionally, the test contract has seen syntactical updates in the unpacking of return values from the simulateTransaction function, improving clarity by ignoring an unused return value.

Changes

Files	Change Summary
src/Strategy.sol	Updated simulateLiquidity function to include simulatedRepoTokenConcentrationRatio as a new output parameter and adjusted its internal logic.
src/test/TestUSDCSellRepoToken.t.sol	Modified unpacking of return values in multiple test functions by removing an unused second return value from simulateTransaction.

Poem

🐰 In the meadow, changes bloom,
New tokens dance, dispelling gloom.
A simulation’s clearer now,
With ratios, we take a bow.
Hopping forth, we cheer with glee,
For code that flows, oh joy to see! 🌼

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

351-353: LGTM! The function signature change enhances functionality.

The addition of simulatedRepoTokenConcentrationRatio to the return values of simulateTransaction provides more detailed information about the concentration ratio.

---

387-395: LGTM! The conditional logic for concentration ratio is sensible.

The logic now calculates simulatedRepoTokenConcentrationRatio only when a valid repoToken is provided, which is appropriate for avoiding unnecessary calculations.
