# Labyricorn Project Template
A starter template and baseline structure for projects compatible with
[Labyricorn](https://www.labyricorn.com).
This template provides the required `.labyricorn/` publishing records, assistant
guidance files (`AGENTS.md`), devlog structure, and the standalone
`devlog_editor.py` management utility for local validation and GUI editing.
---
## Overview
Projects published on Labyricorn maintain their own exhibition pages and
development logs directly inside their Git repositories under the `.labyricorn/`
directory. The Labyricorn site importer periodically synchronizes these records
as read-only content.
This template includes:
- **`.labyricorn/` publishing structure**: Validated Lektor-format records for
project identity and development logs.
- **`devlog_editor.py`**: Standalone GUI and CLI tool for managing devlog entries,
validating publishing contracts, and safely publishing changes.
- **`AGENTS.md` instructions**: Scoped assistant instructions at repository root
and publishing directories to ensure AI assistants adhere to the publishing
contract.
- **`.gitignore`**: Configured exclusions for Python environments, caches, and build
artifacts.

## Getting Started
### 1. Configure the Project Identity
Edit `.labyricorn/project/contents.lr` to set your project details:
```ini
_model: project
---
schema_version: 1
---
project_id: my-project-id
---
title: My Project Title
---
summary:
A concise summary of the project for listings and cards.
---
status: active
---
started: 2026-08-23
---
author: Author Name
---
repository_url: https://git.labyricorn.com/Owner/my-project
---
default_branch: main
---
tags: python, web, tool
---
body:
An exhibition narrative describing the project background, goals, and features.
```
#### Project Fields:
- `project_id`: Stable lowercase hyphenated slug (e.g. `my-project`).
- `title`: Display title for the project.
- `summary`: Short multi-line summary.
- `status`: One of `active`, `released`, `maintained`, or `archived`.
- `started`: Start date in `YYYY-MM-DD` format.
- `author`: Author or organization name.
- `repository_url`: Public credential-free HTTPS Git URL.
- `default_branch`: Target branch name (e.g. `main`).
- `logo`: (Optional) Local filename of an image inside `.labyricorn/project/`.
- `tags`: Comma-separated technology or topic labels.
- `body`: Markdown narrative of the project.
### 2. Configure the Devlog Index
Edit `.labyricorn/devlog/contents.lr` to customize the devlog title and summary:
```ini
_model: devlog
---
schema_version: 1
---
title: My Project development log
---
summary: Milestones and development updates for My Project.
```
### 3. Add Devlog Entries
To add an entry manually, create a directory under `.labyricorn/devlog/<entry-slug>/`
containing `contents.lr`:
```ini
_model: devlog-entry
---
schema_version: 1
---
title: Initial Project Milestone
---
date: 2026-08-23
---
author: Author Name
---
summary:
Overview of the milestone accomplishments.
---
tags: release, setup
---
source_commit: <40-character-commit-hash>
---
body:
Detailed Markdown description of the milestone, technical decisions, and progress.
```
Alternatively, use `devlog_editor.py` to create and edit entries interactively.
---
## Devlog Editor
The included `devlog_editor.py` script is a standalone utility with zero external
dependencies (uses Python standard library and Tkinter).
### CLI Validation
Validate all project and devlog records without opening a GUI:
```bash
python devlog_editor.py --validate
```
### Graphical Editor
Launch the Tkinter management interface to view repository status, draft entries,
and publish updates:
```bash
python devlog_editor.py
```
Features of the GUI editor:
- **Repository status**: Displays current branch, remote, and ahead/behind counts.
- **Entry manager**: Create, edit, and delete devlog entries with automatic slug and date handling.
- **Publishing safety**: Stages and commits only `.labyricorn/` publishing files, leaving application source files untouched.

## Publishing Rules & Constraints
The Labyricorn site importer enforces strict validation rules on imported repositories:
1. **Native Lektor Records**: Records must be named `contents.lr` and declare `schema_version: 1`.
2. **No Raw HTML**: HTML tags (`<script>`, `<style>`, `<div>`, etc.) are prohibited in text fields and Markdown bodies.
3. **Approved Images**: Attachments must be PNG, JPEG, or WebP files located within the record directory. Files must match their magic-byte signatures.
4. **Limits**: Up to 100 imported files, maximum 5 MiB per file, and maximum 20 MiB total per project snapshot.
5. **Source Commits**: Devlog `source_commit` values must be valid 40-character commit hashes existing on the branch history.
6. **No Symlinks or Executables**: Linked paths and executable scripts under `.labyricorn/` are rejected.

## Assistant Guidance (`AGENTS.md`)
This repository uses hierarchical `AGENTS.md` files to guide coding assistants:
- **`AGENTS.md` (Root)**: General project guidelines, authorization boundaries, and devlog practices.
- **`.labyricorn/AGENTS.md`**: Publishing boundary contract and security rules.
- **`.labyricorn/project/AGENTS.md`**: Rules for editing project exhibition metadata.
- **`.labyricorn/devlog/AGENTS.md`**: Standards for crafting verifiable devlog entries.
Coding assistants working in this repository should always review the nearest
applicable `AGENTS.md` before making changes.
