  • Tasks that involve Technical documentation
  • SKILL.md covers Preconditions, Step 1 — Cargo Update Before…, Step 2 — Identify Major… and Step 3 — Update Each Dependency, plus 2 more sections
  • Calls cargo and git

What it does

Update Deps is an agent skill from webern/cargo-readme. Update cargo dependencies to their latest major versions one at a time, verifying each with check/build/test and committing individually. Invoke with /update-deps.

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.

It sits in Development, covering Technical documentation. It works with Rust and Git. The repository describes itself as: Generate README.md from docstrings. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Technical documentation

Example prompts

  • “/update-deps”

Workflow steps

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

  1. Cargo Update Before Major Bumps
  2. Identify Major Version Bumps
  3. Update Each Dependency
  4. Minor/Patch Updates

What it can do on your machine

Read from SKILL.md and the folder at commit d76a96d. 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:

    • cargo
    • git

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

  • Network

    No URLs in SKILL.md. Its commands use git, 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

Update Deps loads about 661 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 353 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~661

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.

Update Cargo Dependencies

Update each dependency in the root Cargo.toml to its latest major version, one at a time, with verification and individual commits. Then run cargo update for minor/patch updates.

Preconditions

Verify ALL of the following before starting. If any fails, stop and tell the user.

  1. Not on main: git branch --show-current must not be main.
  2. Up to date with main: git fetch origin main, then git rev-parse HEAD must equal git rev-parse origin/main. If not: AskUserQuestion Is this branch OK?
  3. Clean working tree: git status --porcelain must produce no output. If not: AskUserQuestion commit before proceeding?

Step 1 — Cargo Update Before Major Bumps

Run cargo update, then cargo check, cargo build, and cargo test. Fix issues. If there are changes, commit with the message run cargo update

Step 2 — Identify Major Version Bumps

Read the root Cargo.toml. For each crate under [dependencies] (skip [dev-dependencies]), run cargo search <crate-name> --limit 1 to find the latest published version.

Major update rules:

  • 0.x crates: minor version is the major. 0.3 -> 0.4 is major; 0.3 -> 0.3.5 is not.
  • >=1 crates: only the major matters. 1 -> 2 is major; 1 -> 1.5 is not.

Print the list: <name>: <current> -> <latest-major>. If none, skip to Step 3.

Step 3 — Update Each Dependency

Process each major update sequentially. For each:

  1. Edit Cargo.toml — change the version to the new major using least-specific semver. Preserve features and other attributes.
  2. cargo update — refresh Cargo.lock.
  3. Verify — run cargo check, cargo build, cargo test in order. If any step fails, read the errors and fix them. Repeat until all three pass. Don't give up after one attempt — breakage from major bumps is expected. Fix warnings in source code, not in test expectations.
  4. Commit — stage all changes. Message format: update <dep> from <old> to <new> using least-specific versions (e.g. update toml from 0.8 to 0.9).

Step 4 — Minor/Patch Updates

  1. Run cargo update
  2. If Cargo.lock changed (git diff --quiet Cargo.lock), commit it: run cargo update
  3. If unchanged, tell the user.

Completion

Summarize: which deps got major updates (from/to), whether cargo update changed anything, total commits created.
