Revyl Codex Dev Loop

Revyl Codex Dev Loop

Use this skill for an authorized Revyl development loop in Codex. This plugin has no hooks and no MCP server. Installation never changes an app's source or .revyl/config.yaml; later source/configuration work is allowed only when the task explicitly requires it and the user authorizes it.

Launcher and setup

Resolve the launcher from this skill's own absolute directory before changing to the app directory. On POSIX use ../../scripts/launch-revyl; on Windows use ../../scripts/launch-revyl.cmd. Call that absolute launcher for every Revyl command; do not use revyl from PATH, PLUGIN_ROOT, or another installed CLI.

SKILL_DIR="<absolute directory containing this SKILL.md>"
LAUNCHER="$(cd "$SKILL_DIR/../../scripts" && pwd)/launch-revyl"
"$LAUNCHER" --version
"$LAUNCHER" auth status

REM Windows cmd.exe
set "SKILL_DIR=<absolute directory containing this SKILL.md>"
set "LAUNCHER=%SKILL_DIR%\..\..\scripts\launch-revyl.cmd"
"%LAUNCHER%" --version
"%LAUNCHER%" auth status

If authentication is needed, use "$LAUNCHER" auth login. An existing environment-provided secret may authenticate the launcher without being copied or named in an argument. Never run credential-provisioning or secret-bridge commands, print credentials, or paste them into chat. Post the normal login approval URL as a clickable link and wait for approval; do not claim that a browser opened.

Authorization and selection

Before any build, remote session, cloud device, or paid operation, require authorization naming the app, environment, and paid operation. Resolve the exact profile and platform from the repository, task, and user context without changing them; ask only when they remain ambiguous. Run from the app directory that owns .revyl/config.yaml, not the monorepo root. Let dev create its new context, capture the returned context and session IDs, and clean up only those resources when the work ends or fails.

For native or rebuild-first apps, use the detached remote loop with explicit selection and no browser opening:

"$LAUNCHER" dev --profile <exact-profile> --platform <ios-or-android> \
  --remote --detach --json --no-open

Return the handshake's viewer_url immediately without opening it. A viewer or --wait-ready only means the session is available, not that the current build succeeded. Wait for the build to reach its terminal success state before claiming a build result.

Use short-lived commands in separate calls. Target the returned context with --context for status and rebuild, and pass it positionally to stop:

"$LAUNCHER" dev status --context <returned-context>
"$LAUNCHER" dev rebuild --context <returned-context> --wait --timeout 600 --json
"$LAUNCHER" dev stop <returned-context> --json

Target every device command with -s <returned-session-id>. Open each captured screenshot before describing it. A false or missing semantic verdict is a failed validation, but cleanup still runs for the returned context/session. Bound status polling to the configured build timeout. If that limit expires, report a timeout and stop the owned loop instead of polling indefinitely.

Detailed CLI mechanics

Resolve this skill's ../../references/revyl-cli-dev-loop.md to an absolute path and read it for framework behavior, evidence, and troubleshooting. This skill overrides that reference whenever they conflict:

• Do not use its browser-opening, URL-opening, foreground, persistent-shell, PATH, or installed-CLI examples. Use --detach --json --no-open and the absolute launcher above.
• Do not start a local app source/configuration change, a device, build, or paid action without the named authorization above.
• Do not install, enable, configure, or invoke revyl-cli-auth-bypass. That skill is not shipped with this plugin, and authentication bypass is never an automatic fallback.
• Use exact resolved profile and platform values, and clean up only the context and session created for the authorized request.

Report an unavailable authorization or ambiguous target instead of guessing.
