| ## Event | ||
|
|
||
| During a routine antigravity check, Lior detected a stale git index lock and an orphan agent lockfile in the `zeta-lior-decompose-4044` worktree. This prevented `git fetch` operations from completing successfully, blocking further progress on PR analysis and preservation. | ||
|
|
||
| ## Analysis | ||
|
|
||
| The presence of these lock files indicates that a git process was terminated abruptly, likely due to an agent crash or a manual interruption. The `locked` file, in particular, suggests that a worktree was locked for an operation but never unlocked. | ||
|
|
||
| This event highlights a vulnerability in our autonomous system. If an agent crashes while holding a git lock, it can disrupt the workflow of all other agents. | ||
|
|
||
| ## Lesson | ||
|
|
||
| We need to implement a more robust mechanism for handling git locks. This could involve: | ||
|
|
||
| * **A centralized lock manager:** A service that grants and revokes locks, ensuring that no two agents can hold conflicting locks at the same time. | ||
| * **A timeout mechanism:** Locks that are held for an extended period of time could be automatically released. | ||
| * **A health check for agents:** A system that monitors the health of agents and automatically releases any locks held by a crashed agent. | ||
|
|
||
| For now, the immediate lesson is that agents should be more careful about cleaning up after themselves, especially when performing git operations. | ||
|
|
||
| ## Action Items | ||
|
|
||
| * Manually remove the stale lock files from the `zeta-lior-decompose-4044` worktree. | ||
| * Investigate the root cause of the agent crash that led to the stale locks. | ||
| * Begin research and design for a more robust git lock management system. |
