-Environment variables you can pass before the command:
-- `CODEX_COMMAND_TEMPLATE` – override the Codex CLI invocation for the resume customization run (defaults to `codex prompt --input {prompt} --output {output} --format markdown`).
-- `CODEX_NORMALIZER_COMMAND_TEMPLATE` – optional override for the job-description normalization run (defaults to the same value as `CODEX_COMMAND_TEMPLATE`).
+- Environment variables you can pass before the command:
   - `POLL_INTERVAL_SECONDS` – watcher polling cadence (default `5`).
   - `CODEX_TIMEOUT_SECONDS` – hard timeout for Codex calls (default `600`).
   - `CODEX_CONFIG_DIR` – optional override for the host directory that should mount into `/home/codex/.codex`.
 
+The container bundles the Codex CLI and expects the caller to mount their `~/.codex` directory for credentials.

 ## Troubleshooting
 - If Codex CLI fails, the job description moves to `ForCustomizing/failed/`. Check container logs, adjust the Markdown, then requeue it.
 - Fatal errors (multiple resumes, multiple job descriptions, missing template, or missing Codex binary) stop the container. Resolve the issue and restart via the wrapper.
-- To change the Codex command format, pass a quoted template (e.g., `CODEX_COMMAND_TEMPLATE='codex run --input {prompt} --output {output}' ./run-input-processor.sh up -d'`). The template must include `{prompt}` and `{output}` placeholders.
+- The watcher logs the exact `codex prompt --input … --output … --format markdown` command before each invocation; inspect container logs if troubleshooting is needed.

+### Codex CLI
+- The container image installs the official Codex CLI and expects credentials/configuration from the mounted `~/.codex` directory on the host.
+- No additional command-line customization is required; the watcher invokes `codex prompt --input … --output … --format markdown` internally for both passes.

 ### Key Environment Variables
-- `CODEX_COMMAND_TEMPLATE` – format string for the resume-customization Codex run (placeholders: `{prompt}`, `{output}`).
-- `CODEX_NORMALIZER_COMMAND_TEMPLATE` – optional override for the normalization Codex run (defaults to `CODEX_COMMAND_TEMPLATE`).
 - `POLL_INTERVAL_SECONDS` – watch loop delay (defaults to 5).
 - `CODEX_TIMEOUT_SECONDS` – wall-clock timeout for each Codex call (defaults to 600).
 - `CODEX_CONFIG_DIR` – host path to mount as `/home/codex/.codex` (defaults to `${HOME}/.codex` via the wrapper).
