file_reader: Research & Knowledge for AI Agents | OpenAgentSkill

Overview

Read and summarize text-based file types only. Prefer read_file for text formats; use execute_shell_command for type detection when needed. PDF/Office/images/archives are handled by other skills.

Read full documentation

Source documentation, not instructions for this website. Review permissions before running any commands.

File Reader Toolbox

Use this skill when the user asks to read or summarize local text-based files. PDFs, Office documents, images, audio, and video are out of scope for this skill and should be handled by their dedicated skills/tools.

Quick Type Check

Use a type probe before reading:

file -b --mime-type "/path/to/file"

If the file is large, avoid dumping the whole content; extract a small, relevant portion and summarize.

Text-Based Files (use read_file)

Preferred for: .txt, .md, .json, .yaml/.yml, .csv/.tsv, .log, .sql, ini, toml, py, js, html, xml source code.

Steps:

Use read_file to fetch content.
Summarize key sections or show the relevant slice requested by the user.
For JSON/YAML, list top-level keys and important fields.
For CSV/TSV, show header + first few rows, then summarize columns.

Large Logs

If the file is huge, use a tail window:

tail -n 200 "/path/to/file.log"

Summarize the last errors/warnings and notable patterns.

Out of Scope

Do not handle the following in this skill (they are covered by other skills):

PDF
Office (docx/xlsx/pptx)
Images
Audio/Video

Safety and Behavior

Never execute untrusted files.
Prefer reading the smallest portion necessary.
If a tool is missing, explain the limitation and ask the user for an alternate format.

# File Reader Toolbox

## Quick Type Check

Use a type probe before reading:

```bash
file -b --mime-type "/path/to/file"
```

If the file is large, avoid dumping the whole content; extract a small, relevant portion and summarize.

## Text-Based Files (use read_file)

Preferred for: `.txt`, `.md`, `.json`, `.yaml/.yml`, `.csv/.tsv`, `.log`, `.sql`, `ini`, `toml`, `py`, `js`, `html`, `xml` source code.

Steps:

1. Use `read_file` to fetch content.
2. Summarize key sections or show the relevant slice requested by the user.
3. For JSON/YAML, list top-level keys and important fields.
4. For CSV/TSV, show header + first few rows, then summarize columns.

## Large Logs

If the file is huge, use a tail window:

```bash
tail -n 200 "/path/to/file.log"
```

Summarize the last errors/warnings and notable patterns.

## Out of Scope

Do not handle the following in this skill (they are covered by other skills):

- PDF
- Office (docx/xlsx/pptx)

## Safety and Behavior

- Never execute untrusted files.
- Prefer reading the smallest portion necessary.
- If a tool is missing, explain the limitation and ask the user for an alternate format.

Review the source

Skill source recorded

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

License: Apache-2.0

Dependency or permission surface needs review
Permission surface may require sandboxing
Quality score needs review
Permission surface needs review: secrets or environment access, shell or command execution
Stars/forks activity: 121 stars, 33 forks; issue activity unavailable in current metadata
Dependency/runtime risk: command execution surface, credential or environment access
Permission surface: secrets or environment access, shell or command execution

Open full audit

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
