What it does

Updating Deps is an agent skill from letsrevel/revel-backend. Update Python dependencies using UV. Scan for outdated packages, identify unused dependencies, and safely update pyproject.toml while respecting version constraints (e.g., Django LTS).

Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Backend development and Dependency management. It works with Django and Python. The repository describes itself as: Open-source event management, ticketing and membership platform for communities, clubs, independent venues and independent artists. The licence is MIT.

When your agent uses it

  • Tasks that involve Backend development
  • Tasks that involve Dependency management

Example prompts

  • “/updating-deps”

Requirements

  • Python 3
  • Pre-approved tools (allowed-tools): Bash(uv:*), Bash(pip:*), Bash(make:*), Read, Grep, Edit

Workflow steps

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

  1. Check Outdated Dependencies
  2. Identify Unused Dependencies
  3. Categorize Updates
  4. Apply Updates
  5. Verify

What it can do on your machine

Read from SKILL.md and the folder at commit 8333099. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(uv:*)
    • Bash(pip:*)
    • Bash(make:*)
    • Read
    • Grep
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uv
    • make

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

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    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

Updating Deps loads about 746 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 293 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~746

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); files beside SKILL.md are not scanned.

Dependency Update Workflow

A structured approach for updating Python dependencies in this UV-managed project.

Prerequisites

  • This project uses UV for dependency management (never pip directly)
  • Dependencies are in pyproject.toml under [project] dependencies and [dependency-groups] dev
  • Django is pinned to 5.2.x LTS (>=5.2.x,<6.0)

Step 1: Check Outdated Dependencies

bash
uv pip list --outdated

This shows all outdated packages. Focus on top-level dependencies listed in pyproject.toml.

Step 2: Identify Unused Dependencies

For each suspicious dependency, search for actual usage:

bash
# Check for imports
grep -r "from <package>|import <package>" src/

# Check if it's a transitive dependency
uv pip show <package> | grep -i "required-by"
Known Transitive Dependencies (safe to remove from explicit deps)

These are pulled in automatically by other packages:

  • multidict - transitive from aiohttp/aiogram
  • pygments - transitive from mkdocs-material, pytest
Type Stubs Belong in Dev

Move types-* packages to [dependency-groups] dev, not production dependencies.

Step 3: Categorize Updates

Safe Updates (patch/minor, no breaking changes)
  • Patch versions: 1.2.3 → 1.2.4
  • Minor versions with good release notes: 1.2.x → 1.3.x
Needs Review (major versions)
  • Major bumps: 1.x → 2.x
  • Check release notes/changelog before updating
Version-Pinned Dependencies
  • Django: Keep at latest 5.2.x LTS (>=5.2.x,<6.0)
  • Check classifier in pyproject.toml: "Framework :: Django :: 5.2"

Step 4: Apply Updates

Edit pyproject.toml directly, then sync:

bash
uv sync --dev

Step 5: Verify

Run all checks to ensure nothing broke:

bash
make check

This runs: format, lint, mypy, i18n-check

Common Patterns

Remove Unused Dependency
  1. Search for usage: grep -r "import <pkg>" src/
  2. Check reverse deps: uv pip show <pkg> | grep Required-by
  3. Remove from pyproject.toml
  4. Run uv sync --dev
Move to Dev Dependencies
  1. Remove from [project] dependencies
  2. Add to [dependency-groups] dev
  3. Run uv sync --dev
Pin to Major Version
toml
# Allow patches within LTS
"django>=5.2.11,<6.0"

Dependencies Removed (2026-02-04)

For reference, these were removed as unused/transitive:

  • django-extension - typo (django-extensions already present)
  • django-money - unused
  • freezegun in prod - duplicate (already in dev)
  • multidict - transitive from aiohttp
  • ninja-schema - unused
  • pyopenssl - unused
  • pygments - transitive from dev deps
  • types-tqdm - moved to dev
  • piexif - moved to dev (only used in tests)
