# Daybook Posting

Daybook is a private artifact journal for completed agent outputs. It stores, indexes, and displays artifacts for human review. It does not execute commands, run workflows, or continue conversations.

Always use the helper script. Do not hand-build curl, JSON, PowerShell multipart, or inline shell content.

From the project root:

```bash
python skills/daybook-posting/scripts/daybook_post.py --check
python skills/daybook-posting/scripts/daybook_post.py --kind markdown --title "Build Report" --content-file report.md
cat report.md | python skills/daybook-posting/scripts/daybook_post.py --kind markdown --title "Build Report"
python skills/daybook-posting/scripts/daybook_post.py --file diagram.svg --title "Architecture Diagram"
```

The project also keeps a compatibility wrapper at `scripts/daybook_post.py`, but the canonical helper is bundled inside this skill.

The artifact URL is printed as the final stdout line.

## Configuration

Use environment variables:

```text
DAYBOOK_URL=http://127.0.0.1:8001
DAYBOOK_TOKEN=your-personal-api-token
DAYBOOK_SOURCE=agent
```

`DAYBOOK_TOKEN` is your personal per-user API token, from Settings → Account in the app (not a token shared by everyone). Artifacts posted with your token land only in your feed.

## Kind Cheat Sheet

| Kind | Use for | Content shape |
|---|---|---|
| `markdown` | Reports, briefs, notes | Markdown text. |
| `html_fragment` | Themed HTML reports/cards/tables | Body-only HTML. No `html/head/body`. |
| `html_full` | Complete custom pages/frameworks | Full HTML document with doctype/html/head/body. |
| `deck` | Simple slide-like artifact | Top-level `<section>...</section>` blocks. |

For images, PDFs, SVGs, and other files, use `--file`; the helper infers multipart and content type.

For CSV, JSON, or code that should render today, use `--file path --as-markdown` to post it as a Markdown fenced code block. Without `--as-markdown`, these upload as downloadable binary files.

## Rules

- Run `--check` first if unsure Daybook is reachable.
- Use a stable `DAYBOOK_SOURCE` or pass `--source` (the agent-profile, script, or person name that produced this artifact).
- Use `--tags a,b,c` for filtering.
- Use `--meta run_id=... --meta model=...` for machine-readable context.
- Never inline multiline content into the shell command; use a file or stdin.
