brag
You built it. Now brag. Turn the project you just created into a short, shareable launch video with one command.
Bottom line: Signal-based grade (4/7 points): very widely starred on GitHub, public source code. This reflects adoption and transparency, not a code review.

What it does
Brag automatically generates short, shareable launch videos from your AI agent or software project with a single command. It captures your work and creates polished video content ready for social sharing and announcements.
Who it’s for
Builders and developers who want to showcase their AI agents or projects without manual video production. Founders and teams launching products who need quick, repeatable ways to create promotional content.
Copy-paste setup
Check these steps against the project’s own instructions before running anything.
Verify against the repo README at https://github.com/latent-spaces/brag (opens external site) for current installation instructions. The project appears actively maintained but setup details should be confirmed directly from the repository.
Risks
- Credential exposure: Tool may require API keys or authentication tokens for video generation services; ensure credentials are never committed or logged
- Prompt injection: User-supplied project descriptions or metadata could be exploited if not properly sanitized before video generation
- Third-party service dependency: Relies on external video generation APIs whose security posture and data handling practices are outside your control
- Supply chain: Dependencies and transitive npm packages should be audited, especially for video processing libraries
- Data retention: Unclear what project data, video metadata, or generated content is retained by upstream services
How to stay secure
Least-privilege permissions
- Grant API keys only read access to project metadata; never allow write or deletion permissions to upstream services
- Use separate, scoped credentials for video generation APIs with expiration dates and rotate every 90 days
- Restrict skill execution to authenticated users with explicit "brag" permission; don't allow anonymous or default-role invocations
- Implement role-based access control limiting who can invoke the skill to project owners or designated team members only
Network isolation
- Enforce TLS 1.2+ for all API calls to video generation services; reject unencrypted connections
- Use VPN or private endpoints when available for third-party API communication to avoid internet exposure
- Implement egress filtering to allow outbound traffic only to whitelisted video generation service domains
- Route all project data through encrypted tunnels; never transmit descriptions or metadata over unencrypted channels
Monitoring
- Log all skill invocations with user identity, timestamp, and sanitized input (never full project descriptions in logs)
- Alert on failed video generation attempts or unexpected API response codes indicating possible service compromise
- Track API key usage patterns; flag anomalies like calls outside business hours or unusual data volumes
- Monitor third-party service status and security bulletins; disable the skill if upstream services report breaches or downtime
Red flags to watch for
- User input containing code templates, variable substitution syntax, or prompt-like patterns (e.g.,
${variable},{{template}}) - API responses containing unexpected file types, executable code, or payloads larger than expected video metadata
- Credentials appearing in error messages, logs, or generated video artifacts
- Skill failures correlating with known vulnerabilities in transitive npm dependencies; audit
