What it does
Project Development is an agent skill from aiskillstore/marketplace. This skill should be used when the user asks to "start an LLM project", "design batch pipeline", "evaluate task-model fit", "structure agent project", or mentions pipeline architecture, agent-assisted development, cost estimation, or choosing between LLM and traditional approaches.
Its SKILL.md is about 3.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `references/case-studies.md`, `references/pipeline-patterns.md` and `scripts/pipeline_template.py`).
It sits in AI & LLM Engineering. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Asks to start an LLM project
- Design batch pipeline
- Evaluate task-model fit
- Structure agent project
Example prompts
- “start an LLM project”
- “design batch pipeline”
- “evaluate task-model fit”
- “/project-development”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Acquire: Fetch raw data from sources (APIs, files, databases)
- Prepare: Transform data into prompt format
- Process: Execute LLM calls (the expensive, non-deterministic step)
- Parse: Extract structured data from LLM outputs
- Render: Generate final outputs (reports, files, visualizations)
What it can do on your machine
Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.comvercel.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Project Development loads about 3.7k tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 76 tokens; SKILL.md has 1,750 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.
Safety
Auto-check passed
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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,750 words (~3,700 tokens).
“This skill covers the principles for identifying tasks suited to LLM processing, designing effective project architectures, and iterating rapidly using agent-assisted development. The methodology applies whether building a batch processing pipeline, a multi-agent research system, or an interactive agent application.”

Can I use Project Development in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aiskillstore/marketplace --skill project-development -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/project-development, .gemini/skills/project-development, .github/skills/project-development and .opencode/skills/project-development in your project.
What does Project Development need to run?
Going by SKILL.md and its folder, Project Development needs Python for the scripts in its folder. Our summary lists: Python 3.
Does Project Development access the network?
SKILL.md names 2 domains. As links in the text: github.com and vercel.com. This is read from the text; nothing was executed.
Is Project Development safe to install?
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. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Project Development use?
No licence was found for Project Development or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
