Plugin End to End

Trigger

• Add or change a plugin type
• Change plugin config schema, execution semantics, or plugin-exposed metadata
• Update plugin chain behavior that affects runtime or tests

Workflow

1. Read change surfaces and module boundaries for plugin context
2. Modify plugin config schema, execution semantics, or chain behavior
3. Run make agent-report ENV=cpu CHANGED_FILES="..." to identify impacted surfaces
4. Run make agent-ci-gate CHANGED_FILES="..." to validate all constraints
5. Verify plugin config, runtime behavior, tests, and E2E cover the changed plugin path

Gotchas

• Plugin behavior spans config and runtime; changing one side without the other creates immediate drift.
• User-visible plugin metadata often affects headers, dashboard display, or E2E expectations even when the core hook code is small.

Must Read

• tools/agent/docs/change-surfaces.md
• tools/agent/docs/module-boundaries.md
• tools/agent/docs/testing-strategy.md

Standard Commands

• make agent-report ENV=cpu CHANGED_FILES="..."
• make agent-ci-gate CHANGED_FILES="..."
• make agent-feature-gate ENV=cpu CHANGED_FILES="..."

Acceptance

• Plugin config and post-decision runtime behavior stay aligned
• Tests and E2E cover the changed plugin path
• User-visible plugin metadata is updated wherever it is displayed
