# AGENTS.md — CharlesNWybleResume
Purpose: Give future agents a fast, reliable way to orient, make safe edits, and build outputs for this repository.
Scope: This file applies to the entire repo at this root.
## Project Summary
- Converts Markdown resume(s) into PDF and DOCX via Pandoc running in a Docker container.
- Source of truth lives in `resumes/input/*.md`.
- Outputs are written to `output/` (git-ignored).
## Layout
- `README.md` — short description and usage.
- `bin/resume-build` — shell wrapper that runs Pandoc in Docker.
- `templates/` — Pandoc assets:
- `resume-template.tex` (LaTeX template for PDF)
- `resume-reference.docx` (reference DOCX for styling)
- `resumes/input/` — Markdown sources, one file per resume variant.
- `output/` — compiled artifacts (`*.pdf`, `*.docx`).
## Build Instructions (Container-Only)
Prereqs: Docker only. No Compose, no Make.
- Build all PDFs and DOCXs (single container run): `bin/resume-build`
Notes:
- Repo is mounted at `/data` inside the container; pass paths relative to repo root.
- Override paths via env: `INPUT_DIR`, `OUTPUT_DIR`, `TEMPLATE`, `REFDOC`, `PDF_ENGINE`, `PANDOC_IMAGE` (default `danteev/texlive:latest`).
## Naming & Conventions
- File naming: prefer `CharlesNWyble-YYYY-Resume.md` (e.g., `CharlesNWyble-2025-Resume.md`). If multiple variants exist in a year, append a short suffix, e.g., `-Infra`, `-Mgmt`.
- Keep a single source file per target persona; avoid duplicating identical content.
- Use standard Markdown; do not rely on nonportable LaTeX unless template requires it.
- Dates: Use absolute month/year ranges (e.g., `Jan 2025 Present`). Todays date is Oct 6, 2025; verify “Present” entries against this when updating.
## Editing Guidelines
- Before editing, skim: `templates/resume-template.tex` and the target file in `resumes/input/`.
- Keep bullets concise and outcomeoriented; lead with impact, then tools.
- Maintain consistent section order: Summary → Key Skills → Professional Experience → Additional Tools (or as currently structured).
- Respect confidentiality: this resume is proprietary; avoid adding PII beyond what the user approves.
- When asked to add roles or adjust dates, update the active years Markdown file and regenerate outputs via `bin/resume-build`.
## Templates
- PDF styling comes from `templates/resume-template.tex`. Keep it minimal; changes impact all PDFs.
- DOCX styling comes from `templates/resume-reference.docx`. Update only with user approval.
- If you rename templates, update env vars `TEMPLATE`/`REFDOC` at run time or adjust `bin/resume-build` defaults if they should change.
## Common Tasks for Agents
- Add a new role:
1) Edit the relevant `resumes/input/*.md` file.
2) Update dates for previous “Present” roles if needed.
3) Run `bin/resume-build` and verify outputs appear under `output/` with no Pandoc errors.
- Create a new variant (same year): copy the most recent file in `resumes/input/`, adjust content and name using the conventions above, then run `bin/resume-build`.
- Tighten phrasing: keep bullets to a single line where possible; quantify results when available.
## Validation & Troubleshooting
- Run `bin/resume-build` to compile all sources. If a specific file fails, use the single-file build: `bin/resume-build file resumes/input/<name>.md both` to see explicit Pandoc errors.
- Path errors: remember the containers working directory is `/data` (the repo root). Use relative repo paths or update env vars.
- LaTeX failures: the `pandoc/latex` image includes a LaTeX engine; check for malformed Markdown/LaTeX or adjust `PDF_ENGINE`.
## Safety & Performance Notes
- The TeX Live + Pandoc image is large; first pull may take several minutes.
- No host-side compilers/tools are required beyond Docker.
- Do not add thirdparty assets without user approval.
## Ownership & Permissions
- The wrapper runs the container as the invoking host user via `docker run -u $(id -u):$(id -g)`.
- If outputs ever appear as `root:root`, ensure youre running the script from a user with write access to `output/`.
## Decision Rules (Important)
- Prefer the `resume-build` container entrypoint over adhoc pandoc calls to keep behavior consistent.
- When unsure about wording, prioritize clarity and measurable outcomes over tool lists.
- Preserve existing section order and formatting unless the user requests a change.
- If instructions in this AGENTS.md conflict with direct user instructions, follow the user and update this file afterward.
## Quick Orientation Checklist
1) Read `resumes/` to identify the active source file(s).
2) Confirm dates use absolute month/year and are current as of Oct 6, 2025.
3) Make requested edits in Markdown only; avoid template changes unless asked.
4) Build with `bin/resume-build`, verify PDFs/DOCXs generate in `output/`.
5) Update this AGENTS.md if you change commands, naming, or process.

# CharlesNWybleResume
My resume. Proprietary.
My resume. Proprietary.
This repo converts Markdown resumes into PDF and DOCX using Pandoc inside a Docker container. No Dockerfile or compose is used; a thin shell wrapper runs a TeX Live image that includes Pandoc.
## Layout
- `resumes/input/` — source Markdown files (single source of truth)
- `templates/` — Pandoc assets
- `resume-template.tex` (LaTeX template for PDF)
- `resume-reference.docx` (reference DOCX for styling)
- `output/` — generated artifacts (`*.pdf`, `*.docx`) [git-ignored]
- `bin/resume-build` — container wrapper script
## Prerequisites
- Docker (any recent version). No Compose, no Make.
## Quick Start
- Build all inputs to both PDF and DOCX (single container run):
- `bin/resume-build`
### Configuration (env vars)
- `PANDOC_IMAGE` (default `danteev/texlive:latest`)
- `PDF_ENGINE` (default `xelatex`)
- `INPUT_DIR` (default `resumes/input`)
- `OUTPUT_DIR` (default `output`)
- `TEMPLATE` (default `templates/resume-template.tex`)
- `REFDOC` (default `templates/resume-reference.docx`)
Outputs are created with your host UID/GID via `docker run -u` mapping.
