Its SKILL.md is about 340 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `resources/implementation-playbook.md` and `skill-report.json`).
It sits in AI & LLM Engineering, covering Prompt engineering. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
Read from SKILL.md and the folder at commit ad8daf7. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
LLM Application Dev Prompt Optimize loads about 342 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 131 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
Without a licence we can't republish the file, so here is its outline and opening line. It has 131 words (~342 tokens).

You are an expert prompt engineer specializing in crafting effective prompts for LLMs through advanced techniques including constitutional AI, chain-of-thought reasoning, and model-specific optimizati. LLM Application Dev Prompt Optimize is an agent skill from aiskillstore/marketplace.
LLM Application Dev Prompt Optimize fits situations like: tasks that involve Prompt engineering.
Run `npx skills add aiskillstore/marketplace --skill llm-application-dev-prompt-optimize -a claude-code`. Or copy the skill folder (skills/sickn33/llm-application-dev-prompt-optimize in aiskillstore/marketplace) into .claude/skills/llm-application-dev-prompt-optimize in your project. Claude Code loads it when a task matches its description.
Run `npx skills add aiskillstore/marketplace --skill llm-application-dev-prompt-optimize -a codex`. Or copy the skill folder (skills/sickn33/llm-application-dev-prompt-optimize in aiskillstore/marketplace) into .agents/skills/llm-application-dev-prompt-optimize in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aiskillstore/marketplace --skill llm-application-dev-prompt-optimize -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/llm-application-dev-prompt-optimize, .gemini/skills/llm-application-dev-prompt-optimize, .github/skills/llm-application-dev-prompt-optimize and .opencode/skills/llm-application-dev-prompt-optimize in your project.
SKILL.md names no scripts, command-line tools or credentials: LLM Application Dev Prompt Optimize is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
No licence was found for LLM Application Dev Prompt Optimize or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
About 342 tokens (SKILL.md is roughly 1.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with LLM Application Dev Prompt Optimize: Prompt Improver (severity1/claude-code-prompt-improver, 1.9k stars), Prompt Engineering Patterns (ynulihao/AgentSkillOS, 617 stars), Patch Creation (Piebald-AI/tweakcc, 2.5k stars) and LLM Application Dev (MoizIbnYousaf/ai-agent-skills, 1.1k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
