Summary

Fixes #139 — published skills return success but are not visible in search.

Root cause: insertVersion always sets moderationStatus: 'hidden' on publish (skills.ts:3180). The only path to 'active' is through approveSkillByHashInternal, called when VirusTotal returns a verdict. Three code paths leave the skill permanently hidden with no recovery:

  1. VT_API_KEY not configuredscanWithVirusTotal logs and returns early, skill stays hidden forever
  2. VT hash not found after 10 poll attemptspollPendingScans marks scan as stale but never activates the skill
  3. VT hash found but no Code Insight after 10 attempts — same stale path, same missing activation

Since toPublicSkill() (public.ts:56) filters out any skill where moderationStatus !== 'active', these skills never appear in search results or on the website despite the CLI returning success.

Fix: Call setSkillModerationStatusActiveInternal in all three paths so the skill becomes searchable. If VT later returns a malicious/suspicious verdict, approveSkillByHashInternal will correctly re-hide and flag it — the existing blocked.malware flag check in toPublicSkill (line 57) is unaffected.

  • convex/vt.ts — 3 activation calls added (no-API-key path + 2 stale paths)
  • convex/lib/public.test.ts — 5 new tests documenting moderation filtering behavior

Test plan

  • All 433 existing tests pass (vitest run)
  • New tests cover toPublicSkill moderation filtering: active, hidden, undefined (legacy), soft-deleted, blocked.malware
  • Lint clean (oxlint --type-aware)
  • Verify on staging: publish a skill with VT disabled, confirm it appears in search

Greptile Summary

This PR fixes a critical issue where published skills would be permanently hidden when VirusTotal scanning fails or times out. The root cause was correctly identified: insertVersion sets moderationStatus: 'hidden' on publish (skills.ts:3180), and without a VT verdict, skills never become searchable.

The fix adds three activation calls to make skills visible when VT scanning is unavailable:

  • When VT_API_KEY is not configured (vt.ts:314)
  • When VT hash is not found after 10 poll attempts (vt.ts:538)
  • When VT hash exists but no Code Insight after 10 attempts (vt.ts:568)

The test additions document the toPublicSkill filtering behavior for various moderation states, which correctly validates that only 'active' skills (or legacy undefined status) appear in search, while hidden, soft-deleted, and malware-blocked skills are filtered out.

Critical issue found: The three new activation calls bypass the quality gate quarantine. Skills with moderationReason: 'quality.low' should remain hidden until manual review (see skills.ts:2335-2344), but setSkillModerationStatusActiveInternal unconditionally sets status to active. Since quality.low skills are included in the pending scan queue (skills.ts:1661), they will be incorrectly activated when VT stales out.

Confidence Score: 2/5

  • This PR addresses a real problem but introduces a quality gate bypass vulnerability
  • The PR correctly identifies and fixes the issue where skills remain permanently hidden when VT scanning fails. However, the fix introduces a critical bug: skills quarantined by the quality gate (moderationReason: 'quality.low') will be incorrectly activated when VT scans time out, bypassing the manual review requirement enforced in approveSkillByHashInternal (skills.ts:2335-2344)
  • Pay close attention to convex/vt.ts - all three activation calls need to check for quality.low quarantine before activating skills

Last reviewed commit: fb76bdf

Published skills stay permanently hidden in search when VirusTotal
cannot produce a verdict. Three code paths leave moderationStatus as
'hidden' with no recovery:

1. VT_API_KEY not configured — scan skipped, skill stays hidden
2. VT hash not found after 10 poll attempts — marked stale, stays hidden
3. VT hash found but no Code Insight after 10 attempts — same

Fix: call setSkillModerationStatusActiveInternal in all three paths so
the skill becomes searchable. If VT later returns a malicious verdict,
approveSkillByHashInternal will correctly re-hide and flag it.

Closes openclaw#139

bypasses quality gate quarantine - skills with `moderationReason: 'quality.low'` will be activated even though they should remain hidden

check the skill's `moderationReason` before activating:

```suggestion
            // Activate the skill so it appears in search — absence of a VT
            // verdict should not permanently hide a published skill.
            const skill = await ctx.runQuery(internal.skills.getSkillByIdInternal, { skillId })
            if (skill?.moderationReason !== 'quality.low') {
              await ctx.runMutation(internal.skills.setSkillModerationStatusActiveInternal, {
                skillId,

Fixed in commit a8e62e2. Added getSkillByIdInternal lookup and check if (skill?.moderationReason !== "quality.low") before activating the skill. This ensures that skills in quality gate quarantine remain hidden even when VT scan is unavailable.

I rather opt to not show a skill than to show one without scan. We are a target.

Thank you for flagging this security concern entirely. You are right that showing skills without a VT scan is too risky given we are a target.

I will revise this PR to remove the activation calls entirely. Instead of auto-activating skills when VT is unavailable/stales, we should:

  1. Keep skills moderationStatus: 'hidden' when VT is not configured or times out
  2. Update the CLI/server response to clearly indicate 'pending_scan' or 'scan_unavailable' instead of incorrectly returning success
  3. Consider a manual admin activation path for the VT-unconfigured case if needed (with explicit approval)

The current fix prioritizes availability over security, which is the wrong tradeoff. I will prepare a revised patch that keeps the quarantine intact and improves observability so publishers understand why their skills aren't appearing.

Let me refactor this to address your feedback.

- Prevent activating skills with quality.low moderation reason
- Add skill lookup and moderationReason check in 3 locations where skills are activated
- This ensures quality gate quarantine is not bypassed when VT scan is unavailable or stale
