What it does

Student Database is an agent skill from MassLab-SII/open-agent-skills. Student database processing tools. Includes grade calculation, duplicate name detection, recommendation letter filtering, and TOEFL score filtering.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `scripts/duplicate_name.py`, `scripts/filter_by_recommendation.py` and `scripts/filter_by_toefl.py`).

It sits in Productivity & Automation. The repository describes itself as: We are dedicated to building a set of open agent skills that deliver superior performance, higher determinism, and greater consistency on targeted tasks, while operating at a… The licence is Apache-2.0.

When your agent uses it

  • Productivity & Automation work in your project

Example prompts

  • “/student-database”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Grade-Based Score
  2. Duplicate Name Finder
  3. Filter by Recommendation Grade
  4. Filter by TOEFL Score

What it can do on your machine

Read from SKILL.md and the folder at commit ece5fab. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 4 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Student Database loads about 1.6k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 493 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Student Database Skill

This skill provides tools for processing student database:

  1. Grade calculation: Calculate student grades from scores
  2. Duplicate name finder: Find duplicate names in database
  3. Filter by recommendation: Find students by recommendation grade
  4. Filter by TOEFL: Find students by TOEFL score threshold

Important Notes

  • Do not use other bash commands: Do not attempt to use general bash commands or shell operations like cat, ls.
  • Use relative paths: Use paths relative to the working directory (e.g., ./student_database).

I. Skills

1. Grade-Based Score

Calculate student grades from student database and generate output files.

Features
  • Read all basic_info.txt files from student folders
  • Extract chinese, math, english scores
  • Calculate grades: A(90+), B(80-89), C(70-79), D(60-69), F(<60)
  • Generate student_grades.csv and grade_summary.txt
Example
bash
python gradebased_score.py ./student_database

# Specify output directory
python gradebased_score.py ./student_database --output-dir ./output
Output Files
  1. student_grades.csv: student_id, name, chinese_score, chinese_grade, math_score, math_grade, english_score, english_grade
  2. grade_summary.txt: Total students, A/B/C/D/F counts per subject, pass/fail counts

2. Duplicate Name Finder

Find duplicate names in student database.

Features
  • Scan all student folders
  • Extract names from basic_info.txt
  • Identify names that appear more than once
  • Generate namesake.txt
Example
bash
python duplicate_name.py ./student_database

# Specify output file
python duplicate_name.py ./student_database --output ./namesake.txt
Output Format
name: xxx
count: xxx
ids: xxx, xxx, ...

name: yyy
count: yyy
ids: yyy, yyy, ...

3. Filter by Recommendation Grade

Find students with specified grade(s) from recommendation_letter.txt files.

Features
  • Filter by single grade (S, A, B, C, D, F) or multiple grades (e.g., SA for S or A)
  • Returns list of matching student folder names
Example
bash
# Filter students with grade S
python filter_by_recommendation.py ./student_database S

# Filter students with grade A
python filter_by_recommendation.py ./student_database A

# Filter students with grade S OR A
python filter_by_recommendation.py ./student_database SA

4. Filter by TOEFL Score

Find students with TOEFL score >= a specified threshold.

Features
  • Reads TOEFL score from basic_info.txt in each student folder
  • Filter by minimum score threshold
  • Returns list of matching student folder names
Example
bash
# Find students with TOEFL >= 100
python filter_by_toefl.py ./student_database 100

# Find students with TOEFL >= 90
python filter_by_toefl.py ./student_database 90

II. Basic Tools (FileSystemTools)

Below are the basic tool functions. These are atomic operations for flexible combination.

Prefer Skills over Basic Tools: When a task matches one of the Skills above, use the corresponding Skill instead of Basic Tools. Skills are more efficient because they can perform batch operations in a single call.

Note: Code should be written without line breaks.

How to Run
bash
# Standard format
python run_fs_ops.py -c "await fs.read_text_file('./file.txt')"

File Writing Tools
write_file(path, content)

Use Cases:

  • Create new files with short, simple content only
  • Overwrite existing files

⚠️ Warning: Do NOT include triple backticks (```) in the content, as this will break command parsing.

Example:

bash
python run_fs_ops.py -c "await fs.create_directory('./new/nested/dir')"

list_directory(path)

Use Cases:

  • List all files and directories in a path

Example:

bash
python run_fs_ops.py -c "await fs.list_directory('.')"

list_files(path=None, exclude_hidden=True)

Use Cases:

  • List only files in a directory

Example:

bash
python run_fs_ops.py -c "await fs.list_files('./data')"

File Operations
move_file(source, destination)

Example:

bash
python run_fs_ops.py -c "await fs.move_file('./old.txt', './new.txt')"

search_files(pattern, base_path=None)

Use Cases:

  • Search for files matching a glob pattern

Example:

bash
python run_fs_ops.py -c "await fs.search_files('*.txt')"

File Information
get_file_info(path)

Use Cases:

  • Get detailed metadata (size, created, modified, etc.)

Example:

bash
python run_fs_ops.py -c "await fs.get_file_info('./file.txt')"

get_file_size(path)

Use Cases:

  • Get file size in bytes

Example:

bash
python run_fs_ops.py -c "await fs.get_file_size('./file.txt')"

get_file_ctime(path) / get_file_mtime(path)

Example:

bash
python run_fs_ops.py -c "await fs.get_file_mtime('./file.txt')"
