# Planr Artifact Use only the public `planr artifact` command. Never invoke `planr-pipeline` directly and never relaunch Codex from inside this skill. 1. For local review, run `planr artifact <file>` or `planr artifact open <file>`. Use `--no-open --json` in headless sessions. Generic artifacts default to the headless `document` presentation. Use `--presentation canvas` only when the user requests spatial/zoomable review; use `--presentation document` to force the reading surface. 2. Sharing is always explicit. Run `planr artifact share <file>` only after the user asks to share. Explain that fragment links contain encoded plaintext; encrypted short links store ciphertext and keep the key in the URL fragment. 3. For returned feedback, run `planr artifact import <review-url>`. Do not add `--allow-stale` without showing the stale-review preview and obtaining the user's explicit approval. 4. Export a completed local session with `planr artifact export <session-id> --format json|markdown`. 5. If the pipeline package is unavailable, report the exact corrective command printed by `planr`; do not bypass the runtime lock or managed state. Local review is loopback-only. Opening, approving, finishing, or importing an artifact never publishes it automatically. Artifact review bundles complete local HTML/CSS/JavaScript and presents it inside an invisible opaque-origin sandbox. It is private review, not standalone website hosting; never describe a share li
