Verl Agent
Website
verl-agent is an extension of veRL, designed for training LLM/VLM agents via RL. verl-agent is also the official code for paper "Group-in-Group Policy Optimization for LLM Agent Training"
Is Verl Agent safe? Thin or incomplete trust evidence. Review carefully before production use.
Compare Verl Agent
How does it stack up against its Agent Frameworks neighbours?
Pick any agent to compare →In detail: Verl Agent scores 50.4/100 (Grade C), ranked #1003 of 1378 tracked open-source AI agent projects, on evidence coverage B (3 of 5 independent signal types). The public evidence: no package-provenance attestation found; OSSF Scorecard rates its supply-chain practices 5.2/10; 60% of recent commits are signed; last pushed 2026-06-09. Every point is earned from checkable signals — never paid placement. How scoring works →
How Verl Agent could raise its score
Each line changes one public signal and recomputes with the live scoring function. The gains don't add up exactly, because the score is capped near the top.
- Raise the OSSF Scorecard from 5.2 to 9.0lowest checks: CII-Best-Practices 0, Fuzzing 0, SAST 0 +8.0 → 58.4 C · #72 of 130

Chain of custody
Scanners check what the code says. This traces who ships Verl Agent and whether that has changed: from the source repository, through how changes are reviewed and released, to the code you run. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities.

Source Partly signed
github.com/langfengQ/verl-agent, Apache-2.0, last pushed 2026-06-09. 60% of the last 100 commits carry a verified signature; the rest can't be tied to a verified identity.

Review and release Mixed
OpenSSF Scorecard rates the repository's practices 5.2/10 (scanned Oct 17, 2026). The checks that decide who can get a change released:
- Code Review3
- Branch Protection6

Verify this score yourself
Every build re-issues Verl Agent’s score as an Ed25519-signed credential, valid for 7 days. You can check it offline against HVTracker’s published key; if anyone changes a number after signing, verification fails.
What this score doesn’t check
It covers who ships the code, not what the code does. It doesn’t read tool descriptions or prompts for injected instructions, watch runtime behaviour, or find bugs nobody has disclosed yet. For that, run a content scanner before you connect it, such as Cisco MCP Scanner or Snyk Agent Scan.

Quick Trust Read
How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade C reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage B is separate — it grades how many independent signal types back the score (3 of 5), so a high score on thin evidence stays visible. Full methodology →

Does Verl Agent publish package provenance?
Does Verl Agent have an OpenSSF Scorecard?
Is Verl Agent actively maintained?
What license does Verl Agent use?
Are Verl Agent's commits signed?
Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.
AI agent surface
MCP, providers, tool surface
These runtime-trust fields — detected from public repo docs and manifests — contribute a bounded adjustment to this project's HVTrust score alongside supply-chain evidence. The exact values each field can add or subtract are documented in the methodology → Compare this surface across every listed agent in the capability matrix →

Detected changes to Verl Agent's runtime surface and supply-chain posture, from daily public-signal snapshots. A change here means our detectors see something different — a genuinely changed capability, or better evidence of an existing one.
Maintain Verl Agent?
For maintainers
HVTrust scores Verl Agent from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
