What it does
Polylith Libs is an agent skill from DavidVujic/python-polylith. Inspect third-party libraries used per Polylith project with poly libs. Use when the user wants to see dependency usage, audit version drift across projects, find which projects use a given library, or compare library declarations vs. the lock file. Read-only — for a CI gate use polylith-check instead.
Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Tooling support for the Polylith Architecture in Python. The licence is MIT.
When your agent uses it
- The user wants to see dependency usage
- Audit version drift across projects
- Find which projects use a given library
- Compare library declarations vs
Example prompts
- “/polylith-libs”
What it can do on your machine
Read from SKILL.md and the folder at commit a7a80f2. 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
Shell commands in SKILL.md call:
uvpoetry
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
Polylith Libs loads about 656 tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 213 words of instructions outside code blocks.
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.

- description
- Inspect third-party libraries used per Polylith project with `poly libs`. Use when the user wants to see dependency usage, audit version drift across projects, find which projects use a given library, or compare library declarations vs. the lock file. Read-only — for a CI gate use `polylith-check` instead.
Libs Skill
Quick command
uv run poly libsCommand prefix: If you do not know the package manager, list lock files with ls uv.lock poetry.lock pdm.lock 2>/dev/null (a pyproject.toml is always present, so it tells you nothing on its own). Use uv run poly (uv), poetry poly (poetry), pdm run poly (pdm), hatch run poly (hatch), or poly (activated venv). Examples below use uv run.
poly libsreports;poly checkfails the build. Uselibsfor inspection,checkfor CI (loadpolylith-check).
Prerequisites
- A Polylith workspace with at least one project.
- A lock file at the root (
uv.lock,poetry.lock, orpdm.lock).
Command reference
| Option | Default | Description |
|---|---|---|
--strict | false | Stricter matching of names and versions across projects. |
--directory | cwd | Limit output to projects whose path matches this directory. |
--alias | — | Comma-separated import_name=package_name aliases. |
--short | false | Compact view — useful for wide workspaces. |
--save | false | Persist the report to a file under the workspace's output dir. |
Examples
# Full library × project matrix
uv run poly libs
# Strict version-drift detection
uv run poly libs --strict
# Compact view for many projects
uv run poly libs --shortHow to read it
- Rows are third-party libraries; columns are projects.
✔= the library is used by that project.- A library used by multiple projects with different versions = version drift. Fix by aligning versions in the relevant project
pyproject.tomls, or by relying on a central lock file (uv workspaces).
Notes for the agent
poly libsis read-only — it never modifiespyproject.tomlor the lock file.
