DEVELOPER INFRASTRUCTURE / AGENT HOOKS
A reusable layer for agent lifecycle automation
Coding agents have many lifecycle events, but project instructions often remain one large document loaded without regard to timing. Hooker makes those moments programmable.
It injects prompts, reminders, checks and context into selected lifecycle events, with reusable recipes for common workflows and a standalone mode that does not require a larger plugin installation.
THE PROBLEM
A rule about compaction matters before compaction. Subagent guidance matters when a subagent starts. A safety check matters before a tool action. Loading everything at session start makes important rules compete with unrelated context.
THE FRAMEWORK
Hooker provides configuration, discovery and reusable recipes for lifecycle automation. A recipe can run merged with other behavior, isolated from it or in standalone mode, depending on how much control the project needs.
THE RESULT
Instead of depending on a reminder buried in a long prompt, projects can define when context appears, what is checked and which workflow behavior should repeat across sessions.
Attach behavior to compaction, tool use, subagents and other lifecycle moments.
Start from reusable patterns instead of writing every hook from scratch.
Carry checks and context rules between projects and installations.
Use selected behavior without a dependency-heavy runtime.
A hook runs at a defined lifecycle event, allowing a project to add context, checks or commands at the moment they are relevant.
A shared instruction file remains useful, but hooks make timing explicit and prevent every rule from consuming attention throughout the entire session.
AGENT INFRASTRUCTURE
We can turn reminders and manual checks into portable lifecycle behavior that stays visible in the project.
