Reviews the current GenVM branch by fanning out three specialized review agents (spec, security, implementation). Use when asked to "review this branch", "review the PR", or do a full code review of a diff.
GenVM Rust test conventions and style. Use when writing, adding, or modifying Rust tests — inline `#[cfg(test)] mod tests`, integration tests under a crate's `tests/`, helpers, assertions, and how `genvm-tool test` discovers them.
Runs tests for the GenVM project. Use after making code changes to verify correctness.

To build the GenVM project:
If ninja fails with missing and no known rule to make it (e.g., after adding/removing/renaming source files), regenerate the build file first:
./configure.rb
This runs the configure.rb Ruby script at the project root, which regenerates build/build.ninja with the current file list.
Build all Rust binaries:
nix develop .#full --command bash .claude/skills/build/scripts/run-ninja.sh -C build all/bin
This runs ninja silently and only shows output on failure (to save tokens).
Available ninja targets:
| Target | Description |
|---|---|
all | Build everything |
all/bin | Build all Rust binaries |
all/data | Build data about runners using Nix |
codegen | Run code generation |
Output locations:
out/bin/genvm-modules - modules binaryout/executor/<version>/bin/genvm - executor binary (one dir per built version, e.g. out/executor/v0.3.0-rc7/; the concrete version comes from executors/<line>.x/manifest.json and is recorded in build/info.json)Runners can only be built on x86_64 using the all target. On other platforms, download them instead.
Download runners:
nix develop .#full --command python3 build/out/bin/post-install.py --create-venv false --default-step false --runners-download true --error-on-missing-executor false
To develop/modify a runner (e.g., cloudpickle):
Enable dev mode:
Set runners/support/versions/dev-mode.nix to true
Set hash to "test":
In runners/support/versions/current.nix, set the runner's hash to "test"
Make your modifications and run tests With dev-mode enabled and hash set to "test", you can build and run tests.
Disable dev mode:
Set runners/support/versions/dev-mode.nix back to false. The build will now tell you to set hashes to null.
Set hashes to null and build:
Set the runner's hash (and dependent runners' hashes) to null, then build:
nix develop .#full --command ninja -C build all
The build will fail with a hash mismatch showing the new hash.
Update hashes:
Copy the new hash from the error message back into hashes.nix. Repeat for dependent runners.
Rebuild to verify: Run the build again to confirm all hashes are correct.
