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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.02420 |
| Opus 5 | $0.00022 | $0.01210 |
| Sonnet 5 | $0.00009 | $0.00484 |
| Haiku 4.5 | $0.00004 | $0.00242 |
Grade A, and why
configure-package-management scanned grade A 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

/configure:package-management
Check and configure modern package managers for optimal development experience.
When to Use This Skill
| Use this skill when... | Use another approach when... |
|---|---|
| Setting up a new project with modern package managers (uv, bun) | Installing a single dependency — run uv add or bun add directly |
| Migrating from legacy package managers (pip, npm, yarn, poetry) to modern ones | Project uses cargo or go mod (already optimal, no migration needed) |
| Auditing package manager configuration for best practices | Configuring linting or formatting tools — use /configure:linting |
| Ensuring lock files, dependency groups, and CI/CD integration are properly configured | Resolving a specific dependency conflict — debug with uv pip compile or bun install --verbose |
| Detecting and cleaning up conflicting lock files from multiple managers | Only need to install dependencies — run uv sync or bun install directly |

Parameters
Parse from command arguments:
--check-only: Report compliance status without modifications (CI/CD mode)--fix: Apply fixes automatically without prompting--manager <uv|bun|npm|cargo>: Override detection (focus on specific manager)
Modern package manager preferences:
- Python: uv (replaces pip, poetry, pipenv, pyenv) - 10-100x faster
- JavaScript/TypeScript: bun (alternative to npm/yarn/pnpm) - significantly faster
- Rust: cargo (standard, no alternatives needed)
- Go: go mod (standard, no alternatives needed)
What ships with it
1 file 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.

configure-package-management is a skill published in the GitHub repository laurigates/claude-plugins (58 stars, last pushed yesterday), licensed MIT. It adds 43 tokens to every session and 2,420 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
