What it does
Checking Uv Locks is an agent skill from agntcy/coffeeAgntcy. Runs task locks:check to confirm every pyproject.toml has a sibling uv.lock that is in sync with it, and fixes any that drifted. Use after adding, removing, or changing a Python dependency or other pyproject.toml setting that affects resolution, or before finishing any change that touches pyproject.toml or uv.lock.
Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Python. The repository describes itself as: End-to-end reference application for AGNTCY Components. The licence is Apache-2.0.
Example prompts
- “/checking-uv-locks”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 78f588c. 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:
uv
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
Checking Uv Locks loads about 417 tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 88 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
- Runs task locks:check to confirm every pyproject.toml has a sibling uv.lock that is in sync with it, and fixes any that drifted. Use after adding, removing, or changing a Python dependency or other pyproject.toml setting that affects resolution, or before finishing any change that touches pyproject.toml or uv.lock.
Checking uv locks
What this skill does
Runs task locks:check (defined in Taskfile.yaml,
wrapping
scripts/checks/check_uv_locks.bash)
to run uv lock --check next to every git-tracked pyproject.toml. This is
the same check task check:all runs as part of
checks.yaml. See
.agents/rules/quality/uv-lock-sync.md
for the underlying rule.
Workflow
- [ ] 1. Run: task locks:check
- [ ] 2. For each flagged project, run `uv lock` in that directory (the
failure message names it) and commit the updated uv.lock together
with the pyproject.toml change
- [ ] 3. For a pyproject.toml with no sibling uv.lock, run `uv lock` in
its directory, or, if it is not a uv project, add a
`# uv-lock-exempt: <reason>` comment to it
- [ ] 4. Re-run task locks:check to confirm it's cleanNotes
- The check never rewrites a lock; only
uv lockdoes. - It resolves against the package indexes, so it needs network access.
- uv is the repo-local pinned binary from
./scripts/setup.sh(.tools/bin/uv); runsource scripts/env.shortask setupfirst if it reports uv not found.
