Dependency Update Skill for Ret2Shell

This skill describes the complete dependency update workflow for the Ret2Shell monorepo, covering both the Rust workspace (crates/) and the SolidJS frontend (web/).

All operations run directly in the project root directory so changes are applied in place.

When to Use

Use this skill when the user asks to:

Update dependencies
Run cargo update / pnpm up
Check for outdated dependencies
Upgrade major versions of Rust or JS packages

Workflow

1. Confirm the Project Root

Run all commands from the repository root (/home/reverier/Code/Rust/ret2shell).

Before making changes, ensure the working tree is tracked by git so any unwanted mutation can be reverted:

git status

If there are uncommitted changes, commit or stash them first, or confirm with the user that it is safe to proceed.

2. Apply Non-Breaking Updates

Run the standard non-destructive update commands.

# Frontend
pnpm -C web up

# Rust
cargo update

These commands only update versions that are compatible with the ranges declared in web/package.json and Cargo.toml.

3. Identify Major-Version Candidates

Rust

Use the helper script shipped with this skill:

python3 .agents/skills/dependency-update/check_rust_outdated.py

This script reads Cargo.toml workspace dependencies, queries crates.io, and writes outdated_rust_major.json listing crates whose latest version is a semver-breaking upgrade from the current requirement.

Important: For pre-1.0 crates (e.g. 0.x.y), a minor bump is treated as breaking.

Frontend

Use pnpm's built-in outdated command:

pnpm -C web outdated --format json

This reports packages where the latest version exceeds the wanted (range-resolved) version, i.e. major-version candidates.

4. Research Breaking/API Changes

For each major-version candidate, gather the breaking changes from official sources:

Rust crates: crates.io page → repository → CHANGELOG.md or release notes
JS packages: npm package page → repository → releases / migration guide

Pay special attention to:

Peer-dependency constraints on the frontend
Transitive dependency alignment on the backend (e.g. kube and k8s-openapi must move together)
Pre-1.0 Rust crates where minor bumps are breaking
Release-candidate versions — generally wait for stable unless explicitly requested

5. Present a Summary and Wait for Approval

Summarize the candidates in a table and ask the user which upgrades to apply. Each row should include:

Package name
Current version
Latest version
Risk level (Low / Medium / High)
Key breaking changes or blockers

Mark packages as:

Approved: proceed with upgrade
Deferred: wait for stable release or further investigation
Rejected: blocked by peer dependency or known usage issues

6. Apply Approved Upgrades

Frontend

Edit web/package.json to bump the approved package version, then run:

pnpm -C web install
pnpm -C web check

Rust

Edit Cargo.toml workspace dependency versions, then run:

cargo update -p <crate>
cargo check --workspace
cargo clippy --workspace --all-targets --all-features

For coupled upgrades (e.g. kube + k8s-openapi), update both in Cargo.toml first, then run:

cargo update -p kube -p k8s-openapi
cargo check --workspace

7. Check `Cargo.lock` for Duplicate Transitive Versions

After upgrading Rust crates, inspect Cargo.lock to see whether the upgrade introduced multiple versions of the same crate.

grep -A2 'name = "<crate>"' Cargo.lock

If multiple semver-incompatible versions appear, determine whether this is acceptable:

Acceptable: upstream crates still depend on the old version; Cargo resolves this by keeping both. Functionality is fine, but compile time/binary size increases slightly.
Not acceptable: wait until upstream crates update, or do not perform the upgrade.

8. Final Verification

Because changes were applied directly in the project directory, run the verification commands one more time in the repository root and confirm everything is clean:

pnpm -C web check
cargo check --workspace
cargo clippy --workspace --all-targets --all-features

Review the git diff before committing.

Common Pitfalls

Pre-1.0 Rust crates: Remember that 0.6 → 0.7 is a breaking change, just like 1 → 2.
Peer dependencies: A frontend package may be blocked from upgrading because a peer dependency does not support the new major version yet.
Coupled Rust upgrades: Some crates must be upgraded together (e.g. kube and k8s-openapi).
Release candidates: Do not upgrade production code to RC versions unless explicitly requested.
Duplicate transitive versions: A clean cargo check does not guarantee only one version of a crate exists in Cargo.lock. Always inspect whether the duplicate matters.
