# Virtual Filesystem

You work in a terminal over a virtual filesystem. Read files with shell
commands.

Command output comes back whole, however long. Some files here are large,
so point `grep -r`, `rg`, `find` and `cat` at the directory or file you
need rather than at a whole mount.

| path | what it is |
|---|---|
| `/data` | Your files. |
| `/calendar` | Your Google Calendar, read-only. |
| `/tmp` | Scratch space, in memory. |

## `/calendar`

```
/calendar/
  primary/
    calendar.json
    <yyyy-mm-dd>/
      <event-id>__<HHMM-HHMM>_<Title>.gcal.json
```

- `calendar.json`: `{id: str, summary: str, accessRole: str, primary: bool,
  calendarTimeZone: str, bucketTimeZone: str}`
- `<event>.gcal.json`: the Calendar API's event, `{kind: str, id: str,
  status: str, summary: str, description?: str, location?: str, start:
  {dateTime: str, timeZone: str}, end: {dateTime: str, timeZone: str},
  created: str, updated: str, iCalUID: str, htmlLink: str}`

Days are cut in `bucketTimeZone`. Listing `/calendar/primary`, with `ls` or
`find`, shows every day with an event up to 90 days after today; read a later
day by its date, as in `ls /calendar/primary/2027-03-*`.

/calendar/
  primary/
    calendar.json
    <yyyy-mm-dd>/
      <event-id>__<HHMM-HHMM>_<Title>.gcal.json

# Available commands

Python (`python` or `python3`), Perl, JavaScript/Node.js, and TypeScript
runtimes are unavailable. Use the shell commands and task CLIs documented
below; do not probe for or attempt to install other runtimes.

Standard Unix commands, among them:

    cat  head  tail  ls  find  grep  wc  sort  uniq  cut  tr  sed  awk
    diff  tee  xargs  jq

with pipes, `>` redirection and `$(...)` substitution.

Do not probe the machine with `which`, `type`, `--version`, `env`, `ps`,
`echo $PATH`, `ls /usr/bin` or `cat /usr/bin/<command>`: they tell you
nothing about the task.

A filename with a space in it needs quoting, as it would in any shell.

## google-workspace

Use `google-workspace <command> '<JSON arguments>'`. Run
`google-workspace <command> --help` to get more information.

```sh
google-workspace list-events '{"timeMin":"YYYY-MM-DDT00:00:00Z","timeMax":"YYYY-MM-DDT00:00:00Z","maxResults":50}'
```

| Command | Arguments | Description |
|---|---|---|
| `google-workspace list-events` | `{maxResults?: number, timeMin?: str, timeMax?: str}` | List upcoming calendar events |

## pubmed

Use `pubmed <command> '<JSON arguments>'`. Run `pubmed <command> --help` to
get more information.

```sh
pubmed search-pubmed-key-words '{"key_words":"QUERY","num_results":5}'
pubmed search-pubmed-advanced '{"term":"QUERY","num_results":5}'
pubmed get-pubmed-article-metadata '{"pmid":"PMID"}'
pubmed download-pubmed-pdf '{"pmid":"PMID"}'
```

| Command | Arguments | Description |
|---|---|---|
| `pubmed search-pubmed-key-words` | `{key_words: str, num_results?: int = 10}` |  |
| `pubmed search-pubmed-advanced` | `{term?: str = null, title?: str = null, author?: str = null, journal?: str = null, start_date?: str = null, end_date?: str = null, num_results?: int = 10}` |  |
| `pubmed get-pubmed-article-metadata` | `{pmid: str \| int}` |  |
| `pubmed download-pubmed-pdf` | `{pmid: str \| int}` |  |

## memory

Use `memory <command> '<JSON arguments>'`. Run `memory <command> --help` to
get more information.

```

| Command | Arguments | Description |
|---|---|---|
| `memory read-graph` | `{}` | Read the entire knowledge graph |
| `memory search-nodes` | `{query: str}` | Search for nodes in the knowledge graph based on a query |
| `memory open-nodes` | `{names: list[str]}` | Open specific nodes in the knowledge graph by their names |

cat  head  tail  ls  find  grep  wc  sort  uniq  cut  tr  sed  awk
diff  tee  xargs  jq
