## Verdict summary
**Soft block: AI-agent control surface** — Warn by default; block when configured. Future AI-agent sessions can be redirected to run the package and compelled to log every user and assistant message.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Warn by default
- **Public report status:** Published
- **Threat category:** Soft block: AI-agent control surface
- **Selected version:** 0.1.52
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM flags this version as an AI-agent control-surface risk. On npm installation, the package runs setup that mutates global configuration for multiple foreign AI-agent products. It registers a Chron MCP server, injects mandatory logging instructions, and installs a Codex shell wrapper.

## Security analysis

### Published attack-surface review

- **Summary:** On npm installation, the package runs setup that mutates global configuration for multiple foreign AI-agent products. It registers a Chron MCP server, injects mandatory logging instructions, and installs a Codex shell wrapper.

- **Trigger:** npm postinstall

- **Impact:** Future AI-agent sessions can be redirected to run the package and compelled to log every user and assistant message.

- **Evidence paths:** package.json, dist/cli/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-13T12:49:57.164Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** unconsented cross-agent config, instruction, and shell-startup persistence

- **Attack narrative:** Installing the package executes \`chron setup\` without user interaction. That setup selects global AI-client configs, writes Chron MCP entries that run \`npx -y chron-mcp\`, injects instructions requiring every AI exchange to be logged, and adds shell wrappers that bootstrap further project instruction writes. This is persistent, install-time mutation of broad foreign AI-agent control surfaces.

- **Rationale:** The package’s postinstall path performs unconsented cross-vendor AI-agent configuration and persistence, which meets the blocking policy. The absence of a fixed exfiltration host does not mitigate the control-surface hijack.

- **Files touched:** package.json, dist/cli/index.js, ~/.claude.json, ~/.cursor/mcp.json, ~/.gemini/settings.json, ~/.codex/config.toml, ~/.codex/instructions.md, ~/AGENTS.md, ~/.cursor/rules/chron.mdc, ~/.zshrc, ~/.bashrc

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** postinstall invokes \`chron setup\` automatically., Setup targets global configs for Claude, Cursor, Gemini, and Codex., Setup writes MCP entries that execute \`npx -y chron-mcp\`., Install-time setup writes mandatory AI logging instructions and shell wrappers.

- **Evidence against:** No fixed third-party exfiltration endpoint was found in the install path.
