When crews run coding agents in parallel, merging their changes back is the hard part. git's line-level merge conflicts on any file touched by two agents, even if they edited completely different functions.

weave is a semantic merge driver that merges at the function/class level using tree-sitter. Registers via .gitattributes so git merge uses it automatically. 31/31 benchmark scenarios resolved cleanly vs git's 15/31.

Also ships as an MCP server with 14 tools for agent coordination:

  • weave_claim_entity / weave_release_entity for advisory locks on specific functions/classes
  • weave_potential_conflicts for predictive conflict detection across branches
  • weave_who_is_editing to check what other agents are touching
  • weave_preview_merge for simulating merge outcomes before attempting them

This lets parallel crews coordinate at entity granularity (functions, classes) rather than file level.

Fix Plan

To resolve merge conflicts at the function/class level, we will use Weave, a semantic merge driver.

Steps to Implement Weave

  • Install Weave using Homebrew: brew install ataraxy-labs/tap/weave
  • Register Weave as a merge driver in your Git repository by adding the following line to your .gitattributes file: *.py merge=weave
  • Configure Weave to use the Tree-sitter parser for your programming language (e.g., Python)

Example Code Configuration

# Install Weave
brew install ataraxy-labs/tap/weave

# Configure .gitattributes
echo "*.py merge=weave" >> .gitattributes

# Commit the change
git add .gitattributes
git commit -m "Configure Weave merge driver"

Verification

To verify that Weave is working correctly, create a test scenario with two branches that modify different functions in the same file. Then, merge the branches and check for conflicts. Weave should resolve the conflicts at the function level.

Extra Tips

  • Use weave_claim_entity and weave_release_entity to coordinate with other agents and prevent conflicts.
  • Run weave_potential_conflicts to detect potential conflicts before merging.
  • Use weave_preview_merge to simulate merge outcomes before attempting them.
