# Project Development Methodology

Decide the shape of the thing before you start building it

## What this does

Early choices on a language-model project are the expensive ones to undo. This is for those: whether a model is even the right piece here, how the stages fit together, roughly what running it costs, and whether one agent or several. Reach for it at the start of a project, not while tuning a single prompt.

### Top 3 things it does for you

- Check whether a language model is the right tool at all
- Lay out a multi-stage pipeline
- Estimate what it will cost to run

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Project Development Methodology

This is for whole-project decisions about systems built on language models, starting with the one people skip: whether a model is the right primitive for the task in the first place.

From there it covers the shape of the work - laying out a multi-stage batch or agent pipeline, estimating tokens and cost, choosing single-agent or multi-agent at the project level, designing structured output for downstream parsing, and structuring agent-assisted iteration.

The unit of work here is a project or pipeline. Individual tool design goes to tool-design, and skill-loading or context-budget tactics to context-optimization.

## Questions

### Is Project Development Methodology safe to install?

AIR scanned this exact version of Project Development Methodology and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit a1841d1ea3da, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/project-development.

### How do I install Project Development Methodology?

Open https://airmarket.ai/app/project-development on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/muratcankoylan/Agent-Skills-for-Context-Engineering/tree/a1841d1ea3dadc70098d94b60fa7a4ab8875dc50/skills/project-development. Install from that link, not the branch.
