## Step: Explore repository structure
Status: complete
What was done: Explored the neovim plugin codebase to locate model configuration files.
Key findings: Default model is set in `lua/explain-it/config.lua` as `openai_chat_model`. Tests use a fake model override so default model changes don't affect tests.

## Step: Update default model to gpt-5.4-codex
Status: complete
What was done: Changed `openai_chat_model` from `"gpt-5"` to `"gpt-5.4-codex"` in `lua/explain-it/config.lua`.
Key findings: Test run command is `make test` (requires `make deps` first if deps folder doesn't exist).

## Step: Run tests
Status: complete
What was done: Ran `make deps && make test` — all 38 tests pass across 7 test files.

## Step: Commit and open PR
Status: complete
What was done: Committed change with message "chore: Add gpt-5.4-codex as default model", pushed branch, and opened PR #18 at https://github.com/tdfacer/explain-it.nvim/pull/18.
