Environment Detection

The CLI auto-detects your AI tool by looking for project markers:

Marker	Tool	Install target
.cursor/ or .cursorrules	Cursor	.cursor/rules/<slug>.mdc
.claude/ or CLAUDE.md	Claude Code	.claude/rules/<slug>.md
.windsurf/ or .windsurfrules	Windsurf	.windsurf/rules/<slug>.md
AGENTS.md	Codex	Project root

Override with --env=cursor, --env=claude-code, or --env=windsurf.

Quality Scores

Every asset on RuleSell is automatically scored on 5 signals — token efficiency, install success rate, schema cleanliness, freshness, and security. No star ratings, no voting.
