Prevent agent drift and silent regressions

Unassisted agents lose context, mutate public API signatures without checking callers, and omit whole-package test verification.

Immutable Hash

Content-Addressed Workspace Baseline

Before reading or modifying code, agentic-go computes an immutable snapshot hash over workspace files and AST structures. All operations are pinned to this Snapshot Ref.

  • i Snapshot hash: sha256:5e3037779544636ea1d...
  • i Workspace containment: symlinks resolved within boundary
  • i Affected package closure: 6 packages computed

FAQ

Questions before you install

Technical details regarding local gopls companionship, execution containment, and safety boundaries.

View All Questions
Does this replace gopls? +
No. agentic-go bundles a pinned gopls v0.21.0 companion named agentic-go-gopls. It uses gopls as a private stdio sidecar for type analysis and symbol references, while building immutable snapshot lineage, change continuity contracts, guarded mutation, and whole-package verification around it.
How does it help open-weight models? +
Open models (DeepSeek, Llama, Qwen, Mistral) excel at code generation, but often lack closed-lab tool harnesses. agentic-go gives them deterministic AST lookups, change contracts to prevent drift, and whole-package test verification - producing results on par with proprietary frontier setups.
Can it modify my files or Git history? +
agentic-go will never mutate Git repository state (it never runs git commit, git add, or branch commands). The only mutating tool is go_refactor, which applies deterministic AST edits only to existing contained non-generated files after rechecking all file preimages against a recovery journal.
What execution privileges does verification need? +
Execution tools compile and run Go test suites with the caller's privileges (same environment as running go test ./... in terminal). All paths are contained and symlink-resolved, but this is containment, not a sandbox. Do not run verification on hostile untrusted repositories.
Is it free and open source? +
Yes : free and open source under the Apache-2.0 license. The project mark is adapted from Maria Letta's Free Gophers Pack under CC BY 4.0.

Free. Open source. Built for Go.
