Rust Rebuild

Use this skill only when the operator explicitly asks Allbert to change its own Rust source.

Safety Contract

• Never edit the source checkout directly.
• Never edit skills/rust-rebuild/ in the source checkout.
• Work only inside the active self-improvement worktree.
• Run the Tier A validation chain before proposing a patch.
• Treat failures as needs-review, not as permission to bypass review.
• Produce a concise summary plus the patch artifact path; do not inline large diffs in chat.

Operating Ritual

1. Confirm that allbert-cli self-improvement config show resolves a source checkout and reports a pinned Rust toolchain.
2. Use the kernel-created worktree path from the self-improvement workflow.
3. Inspect files with read_file and make edits with write_file only inside that worktree.
4. Use process_exec inside the worktree for validation commands.
5. If validation fails, capture the failing command and the relevant output tail.
6. Hand the operator a patch summary and next-step hint for approval.

The rebuild output is a review artifact, not an install action. The operator must explicitly approve and install any patch in a later step.
