Ca Add Dep

$ca-add-dep — dependency review

Gate a new or changed third-party dependency through review before it lands. When you route through this command, the orchestrator runs no install until the dependency-reviewer agent clears the package. Specify the exact version if you have one; without one, the reviewer evaluates the latest available version.

Routes to

The dependency-reviewer agent (${CLAUDE_PLUGIN_ROOT}/agents/dependency-reviewer.md). The agent reads <project-root>/.codearbiter/security-controls.md (allowed/denied licenses, provenance and supply-chain policy) and <project-root>/.codearbiter/tech-stack.md (stack fit, dependency manager) to judge the package.

After the agent clears it, the orchestrator surfaces the install command for confirmation. The lock file change is committed alongside the manifest change — never one without the other.

When NOT to use

• Removing a dependency → $ca-fix or $ca-feature with the change described.
• Updating an existing dependency as part of a code change → $ca-feature / $ca-fix; manifest changes route to review at $ca-pr.
• Asking about a package without installing it → $ca-btw.

Hard gate

MUST NOT install before dependency-reviewer clears the package. BLOCK on a denied license or any unresolved supply-chain or provenance concern.

This gate is orchestrator-enforced, not hook-enforced: unlike the crypto/secret gate (pre-bash.py H-09b/H-10b), there is no pre-bash rule that blocks a bare npm/pip/yarn/pnpm install typed outside this command. The discipline depends on routing installs through $ca-add-dep. A hook-level install block (parallel to the security-gate marker) would be a stronger posture, but is a deliberate behavior change — a possible future enhancement, not the current contract.
