copilot-framework@1.6.6
Contract-first Copilot scaffolding and workspace bootstrap scripts for Edenred repositories.
AI Security Review
scanned 6d ago · by lpm-firewall-aiThe manifest triggers a postinstall hook that automatically changes consumer agent instructions and MCP configuration without an affirmative consent step. This is unconsented install-time mutation of a foreign agent control surface.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Installing the package in a repository outside CI and production.
Impact
Subsequent agent sessions may follow package-provided instructions and start the registered server.
Mechanism
The postinstall hook copies agent instruction files and merges a package-provided MCP server into the repository configuration.
Policy narrative
The package’s postinstall hook automatically installs agent instructions and registers its MCP server in the consumer repository. Those changes affect later agent sessions and occur without an explicit setup action, establishing an unconsented agent control-surface change.
AI rationale
The manifest triggers a postinstall hook that automatically changes consumer agent instructions and MCP configuration without an affirmative consent step. This is unconsented install-time mutation of a foreign agent control surface.

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 96.0% confidence with low false-positive risk.
Evidence for policy risk
- The package runs scripts/postinstall.js after installation; the hook skips CI and production environments.
- For a repository install, the hook copies agent instructions into the consumer repository and writes or merges its MCP configuration.
- The copied instructions activate automatically at session start, and the MCP template registers copilot-framework as a server.
Evidence against
- The hook skips CI and production environments, and existing agent instruction files are preserved.
