Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00112 | $0.02931 |
| Opus 5.5 | $0.00045 | $0.01172 |
| Sonnet 5.5 | $0.00022 | $0.00586 |
| Haiku 4.5 | $0.00011 | $0.00293 |
Grade B, and why
js-deps scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Recursive force deletemediumDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
rm -rf "$DIR/node_modules" "$DIR/package-lock.json" Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
How it starts
The opening of the file, as written. The whole thing — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.
JS Deps
Arguments
Specific package names (e.g. jest @types/jest), . for all packages, or glob patterns (e.g. @testing-library/*).
If $ARGUMENTS is help, --help, -h, or ?, skip the workflow and read references/interactive-help.md.
Workflow Selection
Based on user request:
- Security audit (audit, CVE, vulnerabilities, security): Read references/audit-workflow.md
- Dependency updates (update, upgrade, latest, modernize): Read references/update-workflow.md
- Ambiguous (no clear intent, or invoked with no args and no context): Read references/interactive-help.md to present the interactive help flow.
If the user expresses version preferences (e.g., "only minor and patch", "skip major versions", "only critical CVEs"), apply the filters defined in references/interactive-help.md without requiring an explicit --help invocation.
Shared Process
1. Create Worktree
Create an isolated git worktree so the main working directory is never modified:
TIMESTAMP=$(date +%Y%m%d-%H%M%S)
BRANCH_NAME="js-deps-$TIMESTAMP"
# Prefer a sibling directory to the project root; fall back to $TMPDIR if that's not writable
WORKTREE_PATH="$(dirname "$(git rev-parse --show-toplevel)")/$BRANCH_NAME"
git worktree add "$WORKTREE_PATH" -b "$BRANCH_NAME" 2>/dev/null || {
WORKTREE_PATH="${TMPDIR:-/private/tmp}/$BRANCH_NAME"
git worktree add "$WORKTREE_PATH" -b "$BRANCH_NAME"
}
If both locations fail, the environment likely restricts all writes outside the project. In that case:
Grant write access to either the project's parent directory or
$TMPDIRin your assistant's settings (in Claude Code: add the relevant path to your sandbox allowlist insettings.json) and retry.
All subsequent steps operate within $WORKTREE_PATH. Discovery, installs, edits, and commits all happen there. Paths like cd <directory> in reference files are relative to $WORKTREE_PATH.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
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.

js-deps is a skill published in the GitHub repository WhatIfWeDigDeeper/agent-skills (2 stars, last pushed 19d ago), licensed MIT. It adds 112 tokens to every session and 2,931 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
