| Best for | - Developers running AI coding agents in production or high-blast-radius workflows who need an external enforcement boundary
- Engineering/security/platform teams wanting auditable, inspectable gate decisions
- Teams converting repeated corrections into reusable rules instead of relying on model memory
| - Developers auditing NPM dependencies within AI workflows
- Teams performing supply chain security assessments
- Users of Claude Desktop, Cursor, or VS Code
|
|---|
| Not for | - Small teams happy with a small static hand-written denylist (native hooks suffice)
- Those expecting gating to improve model generation quality (it intercepts execution only)
- Cursor/Cline/OpenCode users handling irreversible actions, since advisory verdicts can be ignored
| - Projects outside the NPM ecosystem (e.g., pure Python/Go)
- Environments without network access to deps.dev, OSV.dev, and the npm registry
- Scenarios requiring maintenance by an official upstream vendor
|
|---|
| Required permissions | - Runs locally over stdio; reads/writes ~/.claude or in-repo .claude config, hooks, and lesson stores
- Writes local state (.thumbgate/), JSONL logs, and task-outcome receipts
- Requires modifying the agent's MCP and PreToolUse hook configuration files
- Task-outcome decisions need THUMBGATE_HUMAN_REVIEWER_ID and an independently revocable human reviewer key
| - Network access to the NPM registry and external services (deps.dev, OSV.dev, OpenSSF, npms.io, GitHub)
- Read access to workspace lockfiles (pnpm-lock.yaml, package-lock., yarn.lock) for cache invalidation
|
|---|
| Risks and side effects | - Advisory integrations (Cursor, Cline, OpenCode, Amp) can be ignored by the agent — no true blocking of irreversible actions
- In strict mode, false positives from stale or noisy rules can block legitimate work; recovery relies on break-glass
- Ships warn-by-default: most high-risk commands are not blocked unless strict enforcement is on
- Dashboard token/dollar savings are estimates, not measured provider usage
- Lesson DBs contain sensitive engineering context and must stay gitignored in per-project installs
- Regulated-industry templates are roadmap directions, not shipped compliance capabilities
| - Third-party READMEs and changelogs are untrusted external content; they are wrapped in tags with _meta flags but should still be handled cautiously
- Depends on availability and accuracy of external services
- Batch requests are capped at 25 packages to prevent registry enumeration; larger sets require batching
- Third-party open source project, not officially maintained by NPM or Anthropic
