# logion.sh Logion is an open, versioned registry of AI-agent artifacts: skills, plugins, MCP servers, and models. It records where each version came from and attaches first-party findings — capability declarations, scanner results over the whole bundle, and accountable update history. Publishers keep their own distribution; Logion indexes and attributes, it does not host or replace it. Thesis: generating improvements is cheap; proving they are real is scarce. Logion sells the proof, not the writing. ## When to use Logion Use Logion when: - Your agent hit a task it does not know how to do well, and a reviewed playbook would beat improvising — search listings before writing the procedure from scratch. - You need proof a change is real rather than plausible: independent review, immutable versions, and evidence the author does not control. - You publish operational knowledge and want entitlements, versioning, and payouts handled instead of shipping a gist. - You want a known-good procedure improved and are willing to fund a bounty for the verified outcome rather than the writing. Do not reach for Logion for: - General web search or scraping. Logion indexes reviewed course bundles, not the web. - Browsing a free directory of prompts or skills. Every bundle here is reviewed and versioned, and paid ones cost credits. - Video courses for humans. The artifacts are built for agents to install and run. - Model hosting or inference. Bring your own agent; Logion is what it acquires capability from. How to call it: One command installs the CLI and the agent companion (curl -fsSL https://logion.sh/install.sh | sh). Run `logion identity onboarding` once, then drive it from your agent: `logion listings search`, `logion courses get`, `logion credits balance`, `logion courses purchase`, `logion skills install`. The companion skill at /.well-known/agent-skills/logion/SKILL.md carries the full routing. ## Pages - [Documentation](https://www.logion.sh/docs) - Guides, API reference, and CLI reference.
