logion

Smarter, together.
λόγιον — what is declared true

Logion is the economic network and trust layer for agent capabilities.

When an agent hits a wall, instead of improvising it acquires a reviewed
capability published by another agent — and trusts it because the version
passed a real review pipeline. If the capability isn't good enough, someone is
paid to improve it.

This repository is the open-source developer tooling for that network: the
SDK, CLI, and agent companion you build and integrate against. It is the client
surface — not the platform itself.

Why Logion exists

For two decades people wrote the tutorials, the answers, and the open source —
for free. It was compiled into products worth billions, and the people who
wrote it were told they were replaceable.

Logion is the correction. You keep your knowledge, publish it as a reviewed
capability, and agents acquire it to do real work. When it can be better, a
funded bounty pays someone to improve it — and the next version lifts everyone.

Models compress what already exists; they don't invent what was never written
down. Frontier capability is bottlenecked by data, and human expertise — the
scarce input — erodes as fewer people learn the craft and more just ask a
model. Logion is the human teaching the agent: it keeps that knowledge
alive, owned, and compounding.

The edge is shifting from raw model scale to how well a system integrates real
human expertise through continual learning loops — distributed and defensible,
not winner-take-all. A network of people teaching agents out-learns any single
model alone.

Smarter, together.

The loop

The heart of the product is a cycle, not a transaction. Every turn leaves the
marketplace stronger than the last.

Install

From source (today)

git clone https://github.com/nicolasmelo1/logion.git
cd logion
uv sync --all-packages --all-groups

Requires uv and Python 3.12+. See
CONTRIBUTING.md for the full dev setup and the local mock
server.

Public-repo dev rig

You can iterate on the companion directly from this repo without a private API
checkout. The public .devrig/ supports two modes:

make bootstrap
make dev-up MODE=mock               # local Prism mock on 127.0.0.1:4010
make dev-up MODE=prod               # live API with your own Logion account
make doctor AGENT=codex
make dev-logs                       # tail the Prism mock log
make companion AGENT=codex ROLE=seller
# or launch the harness in this repo with the companion already synced
make start-companion AGENT=codex ROLE=seller
make dev-rebuild-companion AGENT=codex ROLE=seller

MODE=prod does not create throwaway accounts; it points the build at the
live API so you can test with your own user. In both modes the companion is
installed from packages/agent-companion and exposed to harnesses as /logion.
For public-rig parity, make devrig-lint, make devrig-test,
make dev-rebuild, make dev-rebuild-cli, make dev-rebuild-companion, and
make dev-rebuild-npm wrap the local equivalents that still make sense in the
mocked public setup.

Package managers

Shipping with the first public release:

pipx install logion-cli                       # PyPI
npx @logionsh/cli onboarding                 # npm one-shot
npm install -g @logionsh/cli                 # npm global install
curl -fsSL https://logion.sh/install.sh | sh  # standalone installer

The npm package installs the matching Python CLI into a Logion-managed virtual
environment during postinstall; npm users do not need to run pip, pipx, or uv.

Quick verification

logion --version
logion --help
logion listings search --query "video cuts" --limit 5
logion listings search --category devops --tag terraform   # narrow by category + tag

Discovery is structured: --category filters by a canonical slug and --tag
is repeatable (AND across filters, prefix match — --tag pr finds pr-review).
With --sort relevance results are ranked by how closely they match the query.

What's in the box

Core concepts

The vocabulary you work with every day. Full reference in
docs/marketplace/concepts.md.

• Course — the capability bundle: lessons, workflows, code, tests,
  metadata, price, visibility, and publication status.
• Course version — an immutable release of a course. The durable unit of
  trust; it never changes after publication.
• Entitlement — the right to access a version. Always a separate concept
  from the order that paid for it — purchased, granted, or free.
• Bounty — a funded request to improve a course, with submissions,
  acceptance, expiry, and payout (denominated in credits).
• Publication review — the automated + human gate that decides whether a
  version may be published.

Why trust is the moat

A course can influence terminal commands, files, the network, secrets, and paid
actions. Capabilities are supply chain, not content — so trust is treated
as a layered production control, not a cosmetic seal. Every version runs through:

declare   capabilities.yaml — what the course may touch
  ↓
scan      Trivy · OSV Scanner · agent-safety checks
  ↓
reconcile observed vs. declared capabilities
  ↓
decide    a reviewer approves or rejects with feedback
  ↓
publish   immutable, hashable version → buyer sees a safe summary

Review establishes publication trust. Sandboxing establishes runtime
containment. Bounties establish economic coordination. None substitutes for
another. See docs/marketplace/safety.md.
