# Input Pipeline Overview
|
||
|
||
The input side of ResumeCustomizer prepares job-specific Markdown resumes by stitching together the base resume, a job-description Markdown file, and the shared instruction prompt, then invoking the Codex CLI inside a containerized watcher.
|
||
|
||
## Workflow Recap
|
||
1. Ensure `input/resume/` contains exactly one Markdown resume.
|
||
2. Drop a single job-description Markdown into `input/ForCustomizing/inbox/`.
|
||
3. Start the watcher stack (`input/Docker/run-input-processor.sh up -d`).
|
||
4. The watcher combines the resume, job description, and the resolved instruction prompt (defaulting to `templates/ResumeCustomizerPrompt.md.example`) into a prompt, runs the Codex CLI, and writes the generated resume to `ForCustomizing/outbox/YYYY/MM/DD/HHMM/`.
|
||
5. Successful runs archive the job description under `ForCustomizing/processed/` and copy the prompt used into the same outbox folder. Failures move the job description into `ForCustomizing/failed/` for review.
|
||
|
||
The human operator reviews the Codex output Markdown, makes any edits, and then manually hands it off to the output pipeline for document rendering.
|
||
|
||
## Container Stack
|
||
The watcher lives in `input/Docker/`:
|
||
- `Dockerfile` – builds a Node/Python base image, installs gosu, and prepares a non-root `codex` user.
|
||
- `watch_and_customize.py` – polls the inbox, validates preconditions, resolves the prompt template (`ResumeCustomizerPrompt.md` or its `.example` fallback), constructs prompts, runs Codex, and routes files.
|
||
- `entrypoint.sh` – maps the container user to the caller’s UID/GID and ensures shared directories exist.
|
||
- `run-input-processor.sh` – wrapper around `docker compose` that mounts your `~/.codex` directory and forwards CLI arguments.
|
||
- `docker-compose.yml` – defines the container, volumes, environment variables, and restart policy (`no` so fatal errors halt the stack).
|
||
|
||
### Templates
|
||
- `templates/ResumeCustomizerPrompt.md.example` ships with default Codex instructions.
|
||
- To customize, copy the `.example` file to `templates/ResumeCustomizerPrompt.md` (the `.gitignore` keeps your local overrides out of version control).
|
||
|
||
### Key Environment Variables
|
||
- `CODEX_COMMAND_TEMPLATE` – format string for invoking Codex (placeholders: `{prompt}`, `{output}`).
|
||
- `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).
|
||
|
||
### Prerequisites
|
||
- Docker Engine with the Compose plugin (`docker compose`) or the standalone `docker-compose` binary.
|
||
- A working Codex CLI and credentials in `~/.codex`. The Docker build attempts `npm install --location=global codex-cli`; override or update as needed if packages change.
|
||
|
||
## Failure Modes
|
||
- **Multiple resumes or job descriptions** – watcher exits immediately with a fatal configuration error. Fix the files and restart.
|
||
- **Codex CLI missing or failing** – job description moves to `ForCustomizing/failed/`; inspect container logs, resolve, and requeue.
|
||
- **Timeouts** – treat as failures; adjust `CODEX_TIMEOUT_SECONDS` if Codex regularly needs more time.
