epochly-relay-cli 0.1.20

Relay CLI (rly): Apache 2.0 control surface for the Relay agent reliability OS.

epochly-relay-cli

The rly command-line interface for the Relay agent reliability OS.

This package ships the public Apache 2.0 control surface declared in spec section P (CLI inventory + contract). The W5 milestone (sub-features w5.1 through w5.5) wires the CLI onto the Python SDK (epochly-relay), the canonical schemas (epochly-relay-schemas), and the local sidecar (epochly-relay-sidecar).

Installation (development)

uv sync --all-packages
uv pip install -e packages/cli

After install, rly --version prints version JSON to a piped stdout and a human-readable form to a TTY. Exit code is always 0 on success.

Why JSON-by-default

Relay is a control-plane CLI consumed by CI runners, gate engines, auditors, and other automation. Spec section P pins the rule that piped stdout is machine-parsable JSON; TTY stdout is permitted to render human-readable text. This package implements the rule via sys.stdout.isatty() detection at output emit time.

Why Typer + Click pinned to exact versions

Per VAL-W5-002 (eng plan CQ3), Typer and Click are pinned with the exact operator (==) rather than a range. The CLI's stdout-JSON contract and cross-shell snapshot fixtures depend on Typer's command dispatch and --help rendering; an upstream version bump would invalidate the snapshots. Bumping Typer or Click is a deliberate W5 maintenance feature, not an unattended dependency upgrade.

Process safety

Per CLAUDE.md keystone invariant #3 and .ops/manifest.yaml, sidecar lifecycle commands (rly sidecar start|stop|restart|status) read PID and port from ~/.relay/sidecar.lock and never invoke kill-by-name primitives (pkill, killall). The full lifecycle implementation lands in W5.2.

Banned product copy

This package and every customer-facing surface produced by its distribution pipeline (PyPI long_description, npm description, release notes, embedded sidecar binary string resources) is scrubbed of the banned tokens enumerated in CLAUDE.md (banned pattern #9, spec J.5). The scripts/lint-banned-product-copy.py lint runs in tier-1 plumbing and fails CI on any match.
