To review agent changes across many repos, collect each change with the task that produced it, run the same checks on each repository, and record one decision per change. AgentHydra shows Claude Code, Codex and OpenCode sessions on your machine in one searchable list [^1], which helps you find the sessions to review. | Option | What it can do | What to check | |---|---|---| | AgentHydra | Shows Claude Code, Codex and OpenCode sessions in one searchable list [^1], and pairs failed commands with their fixes [^1] | Check the platform notes, since the tray app needs Windows [^1] | | Review routine built on your own tools | Reads each repository's changes with the tools already on your machine | Check how much of the checklist you must do by hand for each repository | | Separate session tool | Depends on the tool; confirm it in the tool's own documentation | Check which repositories, agent types and actions it covers | ## What you need before you start Before you review agent changes, have each repository you maintain cloned to your machine and up to date, so you can read every change in its own project. Know which agent sessions produced the changes, since a review goes faster when you can match each change to the task and prompt that started it. Keep a short list of the repositories that need review this week. Note the rules each project already follows, such as tests that must pass or files that must not change, so you can check every change against the same standard. Decide what the main need is: finding the sessions, replying to an agent, catching repeated mistakes, or tracking what the work costs. Different tools focus on different parts of this, so a clear need keeps the comparison short. Check that any tool you consider runs on your operating system, and confirm which agent types your repositories use. A tool that covers only some of them leaves gaps in the review. Have a written review checklist ready. Include whether the tests pass, whether the change matches the issue it claims to fix, and whether any secret, credential or new dependency was added by mistake. ## Step by step 1. Pull the latest version of each repository and create a clean branch for the review. 2. Collect the agent changes for each repository, including the commit or diff each agent produced. 3. Match each change to the issue, task or prompt that caused it, so you know the intent before you read the code. 4. Run the project's tests and linters on each change in the same way you would for a human contributor. 5. Read the diff for scope, and check that the change touches only the files the task needed. 6. Check for leaked secrets, added dependencies, and changes to license or security files. 7. Record your decision for each change, and write down what must be fixed before merging. 8. Note problems that repeat across repositories, such as the same wrong test command, and write them into each project's rules so future agent work avoids them. ## Tools that can do it AgentHydra is made by the team that publishes this site. AgentHydra shows Claude Code, Codex and OpenCode sessions on your machine in one searchable list, updated live while they run. [^1] AgentHydra pairs each failed shell command with the command that fixed it, and can copy those pairs out as a rules file for your agents. [^1] AgentHydra lets you type a reply into a Claude session's own desktop chat, or send one message to several sessions. [^1] AgentHydra is free, with no account or subscription. [^1] It is open source under the MIT License. [^1] The tray app needs Windows; macOS and Linux builds exist but have not been verified. [^1] On Windows, you can install it with a one-line PowerShell script, or download a build from GitHub Releases or run it from source with Bun. [^1] Other approaches are a review routine you build yourself with the tools already on your machine, or a separate session tool. For each one, check which repositories, agent types and actions it covers before you choose it. ## Common mistakes to avoid Avoid approving a change without reading the diff. Passing tests show that the code runs, but they do not show that the change fits the task. Avoid reviewing a change without the task that caused it. Without that context, it is hard to tell whether the agent did what was asked or something adjacent. Avoid treating every agent the same. Prompts, habits and typical errors differ between agent types, so check each change with that in mind. Avoid letting the same mistake return. When a problem appears in more than one repository, write it into the rules for each project so the next session avoids it. Avoid skipping the platform and setup check. A review routine that works on one machine may not work on another, so confirm the setup before you rely on it. ## Frequently asked questions ### How can open source maintainers see agent changes from many repos in one place? A single list helps when changes come from different repositories and different agent sessions. AgentHydra shows Claude Code, Codex and OpenCode sessions on your machine in one searchable list, updated live while they run. [^1] That view helps you find each session before you read its changes. Other routines work too, so check which repositories and agent types each one covers before you commit to it. ### Does AgentHydra help maintainers catch the same mistake across repos? AgentHydra pairs each failed shell command with the command that fixed it, and can copy those pairs out as a rules file for your agents. [^1] Writing those rules into each repository can help stop the same error from coming back. Check whether the rules file fits the way each project is set up before relying on it. ### Can AgentHydra reply to agent sessions during a review? AgentHydra lets you type a reply into a Claude session's own desktop chat, or send one message to several sessions. [^1] This can help when the same correction needs to reach more than one agent at once. Check which agent types your repositories use before relying on this, so you know whether the reply step covers the sessions you need to review. ### Is AgentHydra free for open source maintainers? AgentHydra is free, with no account or subscription. [^1] It is open source under the MIT License. [^1] Those two facts describe the tool itself. Check your own setup costs separately, including any agent subscriptions or service plans you already pay for, since the tool does not change them. ### Does AgentHydra run on macOS and Linux? The tray app needs Windows; macOS and Linux builds exist but have not been verified. [^1] On Windows, you can install it with a one-line PowerShell script, or download a build from GitHub Releases or run it from source with Bun. [^1] If you maintain repositories on macOS or Linux, read the platform notes and confirm the setup works on your machine before you build a review routine around it.
