Codedrobe Adapter Dev Skill for Codex

CodeDrobe Adapter Development

Work in the @codedrobe/core repository. Keep the adapter lightweight and prove selectors against a real installed application; never infer renderer compatibility from an app name, executable path, or screenshot alone.

Read the relevant references

• Read references/architecture.md before changing ownership between Core, adapters, renderer profiles, themes, Skills, or Desktop.
• Read references/adapter-contract.md before editing adapter code, exports, host settings, or types.
• Read references/dom-inspection.md before collecting CDP targets or choosing selectors.
• Read references/testing.md before claiming support or updating lastVerified.

Add or repair an adapter

• Inspect the current Core tree, adapter registry, tests, CLI help, and working-tree changes.
• Locate the actual installed app and record its app version/build. Do not overwrite unrelated local changes.
• Launch the real app with loopback CDP on a configurable, unoccupied port. Do not restart or terminate it without authorization.
• Inspect /json/list, select the actual renderer, and run codedrobe dom snapshot on every relevant route to collect privacy-preserving semantic DOM evidence.
• Choose only cross-route landmarks for the adapter: root, sidebar/navigation, workspace/content, and composer/input. Only rootAny should block (it doubles as the boot detector); declare panels the app can hide — sidebars in popped-out or collapsed windows — as recommended, since compatibility is judged per window.
• Put app- or theme-specific layout nodes in theme verification contexts, not the adapter.
• Implement the adapter, registry export, types, and focused tests. Add a renderer profile or host-settings module only when the application requires that behavior.
• Probe the real renderer, then apply and verify a minimal package. Validate the home and conversation contexts separately.
• Restore the renderer and any transactional host settings. Confirm cleanup before finishing.

10. Update lastVerified only after real-app verification succeeds, including the observed version/build and date.

Compatibility failure workflow

• Reproduce with codedrobe probe --app <id> --theme <package>.
• Separate adapter landmark failures from theme-specific missing nodes.
• Inspect the live DOM and computed layout; do not repair from stale documentation alone.
• Prefer a stable alternative selector before broadening any lists.
• Keep failure output concrete: requirement name plus every attempted selector.
• Add a regression test before updating lastVerified.

Guardrails

• Never patch application bundles, app.asar, code signatures, WindowsApps ownership, or user authentication data.
• Bind CDP to 127.0.0.1 and reject occupied custom ports instead of killing unknown processes.
• Avoid generated CSS-module hashes, localized text, deep child chains, and broad selectors such as body * in adapters.
• Keep optional decoration out of adapter requirements.
• Preserve custom installation paths and user-selected CDP ports throughout detect, launch, probe, apply, verify, watch, and restore.
• Do not add a public theme-publishing path until registry authentication and authorization are complete.
