ln-42-dependency-upgrader

ln-42-dependency-upgrader is a skill for Claude Code from levnikolaevich/claude-code-skills. It costs 22 tokens per session (2,677 once invoked), scanned A, original, MIT.

A workflow for upgrading software dependencies in small, reversible batches. Dependencies are external libraries or tools that a project uses.

In plain words
What is it for?
Use it to update dependencies while preserving manifests and lockfiles, checking version-specific compatibility, and testing for regressions.
Why use it?
Dependency upgrades can change compatibility or behavior, so checking versions, runtime support, and regressions helps prevent an upgrade from breaking the product.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ln-42-dependency-upgrader scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Dependency Upgrader

Goal: Upgrade dependencies in small, attributable batches. Preserve manifests, lockfiles, runtime support, and product behavior; do not treat a newer version as valuable without compatibility, security, or maintenance evidence.

Execution contract: The checklist defines completion. Track each item internally as PENDING, PROVEN with evidence, CLEARED with evidence its condition is absent, or UNPROVEN with a gap; reading, delegation, tool failure, a zero exit status, or a self-reported success is not proof; only the observed outcome is. Reconcile after each section. Before returning, resolve all PENDING, count only PROVEN and CLEARED, and apply verdict and approval rules to every gap. Preserve intent, scope, and existing authorization. Continue authorized work; ask only for consequential unresolved choices or required external approval. When no one can answer during the run, state the exact question and apply the skill's verdict for the remaining gap instead of waiting or guessing. Scale depth to material risk without skipping checks. Preserve dependency and safety order; otherwise choose an appropriate verification method. Accept equivalent user or repository evidence; no other skill, named artifact, or complete lifecycle is required. Preserve source requirement and decision IDs. Bind reused evidence to relevant source versions, dirty changes, configuration, and environment; invalidate only affected claims. On continuation, reconcile task, authorization, current state, and unresolved evidence. For long work, return a compact continuation record or update an already authorized artifact; read-only skills do not persist it. Distinguish artifact readiness, verified behavior, and external-action authority. Prepare authorized work before required approval. If blocked by an instruction, cite its exact source and unresolved boundary; do not invent approval gates from caution.

Tool Routing

Need Preferred tool Use it when Fallback
Package-manager detection Manifests, lockfiles, workspace files, runtime files, and repository instructions Always before choosing commands or update scope Build and CI configuration
Outdated and vulnerable packages Native package-manager outdated and audit commands The manager and registry are available Official registry, vendor advisory, and lockfile inspection
Breaking changes and support Official release notes, migration guides, changelogs, advisories, and runtime support tables Every consequential minor, major, replacement, or security update Primary-source repository releases; otherwise mark UNVERIFIED
Usage and blast radius Language server or host-native code intelligence An updated API, type, plugin, build tool, or runtime may affect consumers Targeted import, symbol, configuration, and script search
Safe version changes Native package-manager commands Updating manifests and generated lock state Do not hand-edit lockfiles or emulate package resolution
Verification Repository-defined install, restore, build, lint, type, test, migration, and smoke commands Before changes and after each batch CI and script inspection with explicit unverified status
Diff and rollback Git status, diff, and isolated commits or worktree Protecting user changes and reverting only the failed batch Stop if the batch cannot be isolated safely

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
