+# Trusted Community Publishers
+#
+# This file lists well-known, high-trust skill publishers in the Claude Code ecosystem.
+# Skills from these publishers receive a trust score boost in agent-hunter's ranking.
+#
+# Selection criteria:
+# - Active maintainer with demonstrated commitment (recent commits)
+# - High GitHub reputation (stars + followers)
+# - Publicly recognized in Claude Code / AI agent community
+# - Skills have been manually reviewed by agent-hunter maintainers
+#
+# Format:
+#   handle:         GitHub username or organization
+#   primary_repo:   Main skill repository (owner/repo format)
+#   domains:        Skill focus areas (for relevance matching)
+#   trust_boost:    Score boost (0.0 - 0.30) added to trust_score
+#   note:           Context for humans (stars, followers, specialization)
+#
+# Trust boost guidelines:
+#   0.30 = Official Anthropic repos
+#   0.25 = Well-known educators/maintainers (80k+ stars or 10k+ followers)
+#   0.20 = Established contributors (10k+ stars or 5k+ followers)
+#   0.15 = Active community publishers (5k+ stars or 1k+ followers)
+#
+# Data source: GitHub API verified on 2026-05-14
+# Verification command: gh api repos/{owner}/{repo} --jq '.stargazers_count'
+#                       gh api users/{owner} --jq '.followers'
