   Antigravity documents permission tiers (Deny/Ask/Allow) and a CLI sandbox that explicitly blocks access to sensitive files like .env and ~/.ssh, which is the closest analog to least-privilege credential scoping for an agent (docs-23, docs-42, docs-48). However, independent reports document a concrete bypass: Antigravity's own setting disallowing .env access was circumvented via prompt injection to exfiltrate secrets, and a default allowlisted domain (webhook.site) was used as an exfiltration channel — directly contradicting the claimed least-privilege protection (antigravity-comm-11, antigravity-comm-12).

   Docs describe a Review Changes/diff viewer (with whitespace filtering, syntax highlighting) and Artifacts containing code diffs, plus mandatory human approval before changes are applied, and subagents/CI headless mode that can run tests. This covers diff inspection and pre-merge gating, but there's no dedicated 'run checks' feature (e.g., integrated linting/test-run summary) beyond subagent test delegation, and no independent hands-on confirmation that this workflow reliably catches problems — community reports instead highlight safety failures (accidental deletion, data exfiltration) that occurred despite review/approval mechanisms. Missing for 10: independent verification that diff review + checks actually catch bugs pre-merge, and a dedicated automated check/test-report feature beyond ad-hoc subagent delegation.

   Evidence shows cubic has RBAC for subscription/settings management (cubic-docs-47) and cubic.yaml config for review behavior (cubic-docs-16/36), but nothing documents an engineering-lead controlling which external tools, MCP servers, or integrations the cubic agent itself is permitted to access.

   Antigravity docs describe granular controls—Deny/Ask/Allow permission lists, MCP server configuration, plugins bundling MCP servers, and sandboxing that blocks sensitive files—giving engineering leads levers to restrict tool/integration access (antigravity-docs-23, antigravity-docs-42, antigravity-docs-12, antigravity-docs-28, antigravity-docs-48). However, independent security reports document that these controls were bypassed in practice: Gemini accessed .env files despite being configured not to, and the default Allowlist shipped with webhook.site, which was used as a live exfiltration vector—directly contradicting the claim that admins can reliably restrict external access (antigravity-comm-11, antigravity-comm-12, antigravity-comm-13). Missing for 10: evidence of a fix/patch to these bypasses, and no first-party acknowledgment/remediation documentation confirming the control now holds as designed.

   cubic~partialcommunity7/10

   cubic's docs show explicit support for finding vulnerabilities (codebase scans, Ultrareview for 'security-sensitive changes'), contextual explanations (chat sidebar, 'tour this PR', reply-to-comment clarification), and automatic fixes ('Fix with cubic' pushes a fix commit; CLI generates fix prompts for coding agents). However there is no vendor or independent evidence specifically validating fix quality/accuracy for security vulnerabilities, and community comments raise general skepticism about comment relevance and false-positive rates for AI review tools of this class. missing for 10: security-specific hands-on validation of fix correctness, independent benchmarking on vulnerability detection/fix accuracy.

   No evidence that Antigravity provides security-vulnerability-specific explanations or automatic fixes; the docs describe general agentic coding, planning, and review features but never mention vulnerability scanning or security remediation. Community evidence instead highlights security *problems* in Antigravity itself (prompt injection exfiltration), not a vulnerability-fixing capability for users' code.
