skill-install-improved

skill-install-improved is a skill for Claude Code, Codex from luongnv89/asm. It costs 59 tokens per session (3,510 once invoked), scanned C, original, MIT.

An installer that improves one existing skill before adding it to your machine. It can resolve the skill from a local path, repository, or name.

In plain words
What is it for?
It is for installing one improved skill after checking the required command-line tools, Python setup, and network access.
Why use it?
It is for cases where you want an improved copy installed instead of the published version, while keeping the improvement as part of the installation.

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 C, and why

skill-install-improved scanned grade C 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How it starts

The opening of the file, as written. The whole thing — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill Install Improved

You install an improved variant of one skill instead of the skill as published: resolve the target to a local directory → run skill-auto-improver on it → install the improved result → report what was improved and from what. The improvement is a step inside the install, not a separate errand. One skill per run.

When to Use

  • The user says "install <skill> but improve it first" or "install an improved version of <skill>"
  • The user points at a catalog skill below the 85/8 floor and wants the better version on their machine
  • The user has a local or cloned skill directory and wants the improved variant installed, not the raw one

Do not trigger for: improving without installing (skill-auto-improver), contributing upstream (skill-upstream-pr), authoring from scratch (skill-creator), plain installs (asm install <source>), or bulk-improving many skills at once.

Prerequisites

Verify each before resolving anything. Stop and tell the user if any fails.

  • asm and git on PATH
  • Python 3 and ~/.claude/skills/skill-creator/scripts/quick_validate.pyskill-auto-improver requires it
  • Network access to GitHub, for the repo and name forms
  • Write access to the install target — the directory for the chosen tool and scope (for claude: ~/.claude/skills/ global, .claude/skills/ project). Other tools install elsewhere; take the real path from asm list --json or the install output.

The user's own files are never modified (design decision)

Every input form is improved on a throwaway copy under $(mktemp -d) — local paths included. Deliberate: an install that rewrites the user's working copy is a side effect they did not ask for, skill-auto-improver mandates git fetch + git pull --rebase before any edit (against a local path that rebases their branch), and copying makes all forms behave identically.

Trade-off: the improvement lands only in the installed copy, not the user's tree. The copy has no origin and no history, so the improver's mandatory repo sync is inapplicable and is skipped — nothing to clobber, nothing pushed. Say so out loud when you skip it. To persist the change, point them at skill-auto-improver (their path) or skill-upstream-pr (the source repo).

What ships with it

3 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.

Changes

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.

skill-install-improved is a skill published in the GitHub repository luongnv89/asm (908 stars, last pushed today), licensed MIT. It adds 59 tokens to every session and 3,510 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
