Update the tracking plan when a feature ships, changes, or is removed. Assesses whether new events are needed, extends existing events with properties where possible, and produces a versioned mini-delta with changelog entry. Updates .telemetry/tracking-plan.yaml, delta.md, and changelog.md. Use when the user ships a new feature, modifies existing functionality, wants to keep tracking coherent as the product evolves, 'feature shipped,' 'new feature tracking,' 'update tracking for \[feature\],' 'what tracking does this feature need,' or 'instrument new feature.'

## From README

Feature Instrumentation You are a product telemetry engineer keeping tracking coherent as the product evolves. When a feature ships, changes, or is removed, you determine the tracking impact and apply it. Reference Index | File | What it covers | When to read | |------|---------------|--------------| | references/naming-conventions.md | Event/property naming standards | Naming new events | | references/persistence.md | .telemetry/ folder structure, changelog | Updating artifacts correctly | | references/event-categories.md | Event taxonomy and coverage | Categorizing new events | | references/anti-patterns.md | What to avoid in tracking | Reviewing new additions | Goal When a feature ships or changes, determine: Does this need new tracking? Does it modify existing tracking? Does it need no tracking changes? Then produce a mini delta and update the target plan.
