Get help, share feedback, and discuss your projects with the community.\n\nThis repository includes Rust crates for Forall's local authoring and hosted verification adapters:\n\n— workspace authoring library`crates/forall-authoring`\n\n— local authoring MCP server`crates/forall-mcp-author`\n\n— hosted verification client`crates/forall-hosted-verify`\n\nSee [crates/README.md](/astrio-labs/forall/blob/main/crates/README.md) and the [architecture docs](/astrio-labs/forall/blob/main/docs/architecture.md)\nfor how these relate to the standalone `forall`\n\nbinary.\n\nBuild and test the crates:\n\n```\ncargo test --workspace\n```\n\nThe full agent runtime (TUI, turn loop, sandbox) is distributed only as the prebuilt binary above.\n\nThis repository is licensed under the [Apache-2.0 License](/astrio-labs/forall/blob/main/LICENSE).", "url": "https://wpnews.pro/news/show-hn-forall-an-ai-coding-agent-that-generates-machine-checkable-proofs", "canonical_source": "https://github.com/astrio-labs/forall", "published_at": "2026-07-16 02:16:18+00:00", "updated_at": "2026-07-16 02:55:18.084603+00:00", "lang": "en", "topics": ["ai-tools", "developer-tools", "ai-agents", "artificial-intelligence"], "entities": ["Astrio", "Forall", "GitHub", "Discord", "X"], "alternates": {"html": "https://wpnews.pro/news/show-hn-forall-an-ai-coding-agent-that-generates-machine-checkable-proofs", "markdown": "https://wpnews.pro/news/show-hn-forall-an-ai-coding-agent-that-generates-machine-checkable-proofs.md", "text": "https://wpnews.pro/news/show-hn-forall-an-ai-coding-agent-that-generates-machine-checkable-proofs.txt", "jsonld": "https://wpnews.pro/news/show-hn-forall-an-ai-coding-agent-that-generates-machine-checkable-proofs.jsonld"}}
