Extend zaly

Start with the smallest mechanism that fits the job:

Need	Mechanism
Explain how a project should be worked on	Project instructions
Reuse a prompt with arguments or shell context	Custom commands
Format command inputs and conditional text	Templates
Teach a reusable workflow loaded on demand	Skills
Execute custom integration logic	Plugins
Distribute resources together	Resource packs

User resources apply across projects; project resources travel with a repository. See resource discovery before choosing where to put them.

Keep prompts focused. A short instruction or command is often more maintainable than a plugin. Conversely, use code when something needs deterministic behavior rather than hoping the model will consistently implement it.

Trust

Commands can execute shell snippets, and plugins execute code. Read resources before enabling them. Do not assume the agent's tool permissions sandbox extension code or template evaluation.
