TOGA Technology Team Claude Knowledge System — shared AI coding harness with skills, knowledge base CLI, and project installer for Claude Code.

AI Security Review

scanned 7d ago · by lpm-firewall-ai

No confirmed malicious attack surface was established. The package is a Claude Code team harness that writes .claude workflow files only during explicit CLI use; postinstall only displays instructions.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm postinstall shows instructions; user runs toga-ai/npx toga-ai to install harness

Impact

Project .claude configuration is modified as advertised when explicitly invoked; no unconsented install-time control hijack found.

Mechanism

project-local Claude harness bootstrap and knowledge sync

Rationale

The risky primitives are real, but source inspection shows they support an advertised, user-invoked Claude harness installer; the lifecycle hook exits before project mutation. I found no credential harvesting, hidden payload execution, destructive behavior, or unconsented install-time AI-agent control-surface mutation.

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with medium false-positive risk.

Evidence for block

package.json defines postinstall: node scripts/install.js --post-install.
scripts/install.js user-invoked bin copies skills/agents/hooks/rules/knowledge into project .claude/ and merges .claude/settings.json.
.claude/settings.json template wires Claude Code hooks and broad Bash permissions for project workflow.
scripts/install.js can run npm view and git ls-remote/clone/pull against the declared team repo when not postinstall.

Evidence against

scripts/install.js --post-install prints setup instructions and exits before mutating project files.
Install-time code does not harvest credentials, read arbitrary user files, persist globally, or exfiltrate data.
Network use is package-aligned update/version logic for npm and https://github.com/agilantsolutions/claude.
AI-agent control files are the advertised purpose: a Claude harness installer invoked by toga-ai/npx toga-ai.
Hook scripts inspected are local workflow gates/validators and do not contain hidden payload download or exfiltration.

48Never store passwords in plaintext.

50Never use MD5, SHA1, SHA256, or any fast hash for passwords. These are broken for password storage.
