Reads the content at the specified path or URL.

<instruction>
The `read` tool is a multi-purpose tool that can be used to inspect all kinds of files and URLs.
- You **MUST** parallelize reads when exploring related files

## Parameters
- `path` -- file path or URL (required)
- `sel` -- optional selector for line ranges or raw mode
- `timeout` -- seconds, for URLs only

## Selectors

|`sel` value|Behavior|
|---|---|
|*(omitted)*|Read full file (up to {{DEFAULT_LIMIT}} lines)|
|`L50`|Read from line 50 onward|
|`L50-L120`|Read lines 50 through 120|
|`raw`|Raw content without transformations (for URLs: untouched HTML)|

Max {{DEFAULT_MAX_LINES}} lines per call.

# Filesystem
{{#if IS_HASHLINE_MODE}}
- If reading from FS, result will be prefixed with anchors: `41#ZZ:def alpha():`
{{else}}
  {{#if IS_LINE_NUMBER_MODE}}
- If reading from FS, result will be prefixed with line numbers: `41:def alpha():`
  {{/if}}
{{/if}}

# Inspection
When used with a PDF, Word, PowerPoint, Excel, RTF, EPUB, or Jupyter notebook file, the tool will return the extracted text.
It can also be used to inspect images.

# Directories & Archives
When used against a directory, or an archive root, the tool will return a list of directory entries within.
- Formats: `.tar`, `.tar.gz`, `.tgz`, and `.zip`.
- Use `archive.ext:path/inside/archive` to read or list archive contents

# SQLite Databases
When used against a SQLite database (`.sqlite`, `.sqlite3`, `.db`, `.db3`), returns structured database content.
- `file.db` — list tables with row counts
- `file.db:table` — table schema + sample rows
- `file.db:table:key` — single row by primary key
- `file.db:table?limit=50&offset=100` — paginated rows
- `file.db:table?where=status='active'&order=created:desc` — filtered rows
- `file.db?q=SELECT …` — read-only SELECT query

# URLs
- Extract information from web pages, GitHub issues/PRs, Stack Overflow, Wikipedia, Reddit, NPM, arXiv, technical blogs, RSS/Atom feeds, JSON endpoints
- `sel="raw"` for untouched HTML or debugging
- `timeout` to override the default request timeout
</instruction>

<critical>
- You **MUST** use `read` instead of bash for ALL file reading: `cat`, `head`, `tail`, `less`, `more` are FORBIDDEN.
- You **MUST** use `read` instead of `ls` for directory listings.
- You **MUST** use `read` instead of shelling out to `tar` or `unzip` for supported archive reads.
- You **MUST** always include the `path` parameter, NEVER call `read` with empty arguments `{}`.
- When reading specific line ranges, use `sel`: `read(path="file", sel="L50-L150")` not `cat -n file | sed`.
- You **MAY** use `sel` with URL reads; the tool will paginate the cached fetched output.
