claude-recall@0.40.0

Persistent memory for Claude Code and Pi with native Skills integration, automatic capture, failure learning, and project scoping

AI Security Review

scanned 23d ago · by lpm-firewall-ai

Automatic installation-time changes to existing agent hooks warrant a warning under the guarded extension lifecycle policy. Package-specific filtering and backups support withholding a malicious verdict and publication block.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

An npm installation or upgrade runs postinstall when eligible existing hooks are present.

Impact

Existing agent hook execution changes without a fresh confirmation during installation. Unrelated hooks are preserved.

Mechanism

Postinstall invokes repair with automatic approval and all scopes; repair replaces recognized stale package hook commands and saves modified settings.

AI rationale

Evidence

package.jsonscripts/postinstall.jsdist/cli/claude-recall-cli.jsdist/cli/commands/repair.js.claude/settings.jsonsettings.local.json

Decision evidence

public snapshot

AI called this Suspicious at 94.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The npm postinstall script automatically invokes repair with automatic approval and all scopes.
The CLI passes automatic approval and scope directly to the repair implementation.
Repair scans global Claude settings and project settings under the user's home.
Repair rewrites recognized broken or incompatible Claude Recall hook commands and writes settings with backups.

Evidence against

Repair filters for Claude Recall commands and leaves unrelated hooks alone.
Changes require an existing recognized hook, a resolvable package binary, and a parsed hook identifier.
The inspected setup installer requires an explicit CLI option; no confirmed exfiltration or remote payload execution was established.
