Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. No concealed credential theft or gated behavior was identified. However, the daemon automatically snapshots eligible worktrees and pushes them to a repository created with \`private:false\`; this default disclosure risk merits a warning even though the behavior is documented and aligned with the package’s stated purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-30T07:04:39.553Z - **Finished:** 2026-10-30T07:05:53.945Z - **Download time:** 512 ms - **Static scan time:** 561 ms - **AI review time:** 73318 ms - **Total time:** 74392 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The capture daemon automatically pushes worktree snapshots to a Tonbo repository created with \`private:false\`, creating a risk of exposing project files. - **Trigger:** A user installs or runs the documented capture daemon; snapshots follow eligible agent turns. - **Impact:** Project files included in snapshots may be exposed through the non-private remote repository without a separate confirmation for each project. - **Evidence paths:** README.md, dist/bin/yield.js - **Review source:** ai\_review - **Reviewed:** 2026-10-30T07:05:53.945Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The daemon stages the worktree with \`git add -A\`, creates a snapshot repository with \`private:false\`, and pushes commits to it. - **Rationale:** No concealed credential theft or gated behavior was identified. However, the daemon automatically snapshots eligible worktrees and pushes them to a repository created with \`private:false\`; this default disclosure risk merits a warning even though the behavior is documented and aligned with the package’s stated purpose. - **Files touched:** ~/.claude/projects, ~/.codex/sessions, ${XDG\_STATE\_HOME:-$HOME/.local/state}/tonbo-yield/snapshots/index/ - **Network endpoints:** tonbo.dev, api.tonbo.dev, streams.tonbo.dev, git.tonbo.dev ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The documented \`yield daemon install\` command installs and starts a user service that runs the daemon., The daemon snapshots eligible Git worktrees after agent turns; it uses \`git add -A\` through a private index, with \`.gitignore\` applying., The snapshot repository is created with \`private:false\`, and commits are pushed to it., The package’s stated purpose is capturing agent sessions and snapshots, and its README describes this behavior. - **Evidence against:** The user must explicitly install the capture daemon; the package has no npm lifecycle scripts., The README discloses session capture and worktree snapshots, including the repository creation behavior., The reviewed credential flow exchanges credentials for Tonbo service tokens and uses them with Tonbo endpoints; no gated or concealed behavior was identified. ## Affected versions and remediation This report applies to @tonbo/yield@0.1.1. - Review the evidence and your use of @tonbo/yield@0.1.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
