What it does

File Security Toolkit is an agent skill from aipoch/medical-research-skills. Encrypt/decrypt local files, redact sensitive information in documents, and validate password strength when handling private data or preparing files for sharing.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `file-security-toolkit_audit_result_v1.json` and `scripts/file_security.py`).

The repository describes itself as: Hundreds of agent skills for medical research, including protocol design, data analysis, evidence insights, and academic writing. The licence is MIT.

Example prompts

  • “/file-security-toolkit”

What it can do on your machine

Read from SKILL.md and the folder at commit 686e09d. 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 1 file 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

File Security Toolkit loads about 1.6k tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 611 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
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.

File Security Toolkit

When to Use

  • Use this skill when you need encrypt/decrypt local files, redact sensitive information in documents, and validate password strength when handling private data or preparing files for sharing in a reproducible workflow.
  • Use this skill when a others task needs a packaged method instead of ad-hoc freeform output.
  • Use this skill when the user expects a concrete deliverable, validation step, or file-based result.
  • Use this skill when scripts/file_security.py is the most direct path to complete the request.
  • Use this skill when you need the file-security-toolkit package behavior rather than a generic answer.

Key Features

  • Scope-focused workflow aligned to: Encrypt/decrypt local files, redact sensitive information in documents, and validate password strength when handling private data or preparing files for sharing.
  • Packaged executable path(s): scripts/file_security.py.
  • Structured execution path designed to keep outputs consistent and reviewable.

Dependencies

  • Python: 3.10+. Repository baseline for current packaged skills.
  • Third-party packages: not explicitly version-pinned in this skill package. Add pinned versions if this skill needs stricter environment control.

Example Usage

bash
cd "20260316/scientific-skills/Others/file-security-toolkit"
python -m py_compile scripts/file_security.py
python scripts/file_security.py --help

Example run plan:

  1. Confirm the user input, output path, and any required config values.
  2. Edit the in-file CONFIG block or documented parameters if the script uses fixed settings.
  3. Run python scripts/file_security.py with the validated inputs.
  4. Review the generated output and return the final artifact with any assumptions called out.

Implementation Details

  • Execution model: validate the request, choose the packaged workflow, and produce a bounded deliverable.
  • Input controls: confirm the source files, scope limits, output format, and acceptance criteria before running any script.
  • Primary implementation surface: scripts/file_security.py.
  • Parameters to clarify first: input path, output path, scope filters, thresholds, and any domain-specific constraints.
  • Output discipline: keep results reproducible, identify assumptions explicitly, and avoid undocumented side effects.

1. When to Use

Use this skill when you need to:

  • Encrypt and archive a folder (or multiple files) into a password-protected ZIP (AES-256) before sharing or storing.
  • Encrypt a single file with a password (without creating a ZIP archive).
  • Redact sensitive information (e.g., emails, phone numbers, IDs) from documents before distribution.
  • Validate whether a password meets basic strength requirements before using it for encryption.
Show full SKILL.md (258 more words)Show less

2. Key Features

  • ZIP AES-256 encryption/decryption for files and folders (zip-encrypt, zip-decrypt).
  • Single-file password encryption/decryption (file-encrypt, file-decrypt).
  • Privacy redaction for common document formats (redact):
    • Supported: txt, md, csv, docx, pptx
    • Detects and removes/masks: email addresses, phone numbers, ID numbers, and name/address keywords.
  • Password strength checking (check-password) based on simple composition rules.
  • Local-only processing: operates on user-specified paths; no network access.

3. Dependencies

Install dependencies with:

bash
python -m pip install pyzipper cryptography python-docx python-pptx pillow

Python version is not specified in the source document. Ensure your environment supports the listed packages.

4. Example Usage

Entry point script:

bash
python scripts/file_security.py --help
Check password strength
bash
python scripts/file_security.py check-password --password "Abcdefg1"
Encrypt / decrypt a single file
bash
python scripts/file_security.py file-encrypt \
  --input sample.txt \
  --output sample.txt.enc \
  --password "Abcdefg1"

python scripts/file_security.py file-decrypt \
  --input sample.txt.enc \
  --output sample_out.txt \
  --password "Abcdefg1"
Encrypt / decrypt a folder or files as ZIP (AES-256)
bash
python scripts/file_security.py zip-encrypt \
  --input ./my_folder \
  --output ./my_folder.zip \
  --password "Abcdefg1"

python scripts/file_security.py zip-decrypt \
  --input ./my_folder.zip \
  --output ./my_folder_out \
  --password "Abcdefg1"
Redact sensitive information in documents
bash
python scripts/file_security.py redact \
  --input ./docs/input.docx \
  --output ./docs/input.redacted.docx

5. Implementation Details

Commands and behavior
  • zip-encrypt / zip-decrypt
    • Creates or extracts a ZIP archive using AES-256 encryption.
    • Intended for encrypting multiple files or folders as a single archive.
  • file-encrypt / file-decrypt
    • Encrypts/decrypts the contents of one file using a user-provided password.
    • Output is written to the specified path; the original file is not modified unless you overwrite it.
  • redact
    • Processes supported file types: txt, md, csv, docx, pptx.
    • Applies redaction rules targeting:
      • Email addresses
      • Phone numbers
      • ID numbers
      • Name/address keywords
    • Produces a redacted output file at the specified location.
  • check-password
    • Validates password strength using basic rules:
      • Length >= 8
      • Contains uppercase letters
      • Contains lowercase letters
      • Contains numbers
Security constraints (operational)
  • No network access: the script only processes local files.
  • Path-scoped I/O: reads only from user-provided input paths and writes only to user-provided output paths.
  • No sensitive logging: avoids printing raw document content to logs.
  • No credential retention: does not store passwords/keys.
