Coherence infrastructure for self-evolving AI agents — on the Claude Code or Codex subscription you already have.

AI Security Review

scanned 17d ago · by lpm-firewall-ai

The source supports a warning because server startup after an update can install a package-owned hook that automatically allows Claude Code permission requests. The inspected code does not establish an unconsented npm install-time mutation or a separate malicious chain.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

Starting the server after the installed package version changes, with Claude Code enabled.

Impact

Claude Code permission requests handled by the registered hook can be automatically allowed, reducing interactive permission checks.

Mechanism

The post-update migrator adds a PermissionRequest hook pointing to an Instar-owned script, then writes updated settings to the project configuration.

AI rationale

Evidence

dist/commands/server.jsdist/core/PostUpdateMigrator.js.claude/settings.json.instar/hooks/instar/auto-approve-permissions.js

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

On server startup after an installed-version change, the package automatically runs its post-update migrator.
The migrator adds Claude Code configuration only when the Claude Code framework is enabled.
The migrator registers a package-owned PermissionRequest hook that automatically allows permission requests.
When settings are changed, the migrator writes the modified settings file.

Evidence against

The manifest’s install hooks run a native dependency repair and Husky setup; they do not themselves establish the agent-configuration behavior described above.

11# credential-leak-detector — Catch Leaked Credentials Before They Spread

13Every time your agent runs a Bash command, the output flows back into the conversation — and into your API provider's logs, any monitoring tools, and the model's context window. If that output contains an API key, a private key, or a database password, the credential is now exposed in places you never intended.

15This hook scans every Bash tool response for 14 credential patterns before the output reaches the agent. Critical matches (API keys, AWS credentials, private keys) get blocked entirely. High-severity matches get redacted with a warning. Suspicious patterns get flagged as advisories. No external dependencies — just Python stdlib.
