Chemical X Protocol: Private drop-in architecture starter kit and capsule generator

AI Security Review

scanned 1d ago · by lpm-firewall-ai

Source inspection shows agent-facing project configuration is written through explicit setup actions, with protections for existing hand-authored files. This is a warning-level agent configuration capability, not a confirmed install-time attack.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A user selects the installer setup option or invokes the pillars wizard with writing enabled.

Impact

The resulting project configuration can influence coding agents used in that project.

Mechanism

The wizard writes generated agent instructions and can update a marked protocol block in AGENTS.md.

AI rationale

Evidence

cli/installer.jscli/pillars-wizard.jscli/host-shims.jscli/host-protocol.jsAGENTS.mdCLAUDE.md.cursorrulesllms.txt.chemx/config.json

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest runs a postinstall script, but its direct-run path prints a registration hint; it does not perform the configuration setup.
Agent-facing project files are written only when the wizard's write conditions allow it; the wizard exposes an explicit write option and the installer routes a setup selection to that option.
Generated host instructions can affect agent behavior, and protocol setup can update a marked block in AGENTS.md.
The error catcher sanitizes report fields and formats GitHub issue URLs; issue posting requires explicit opt-in.

Evidence against

The inspected source does not show install-time agent configuration changes or another confirmed attack.
