Review Change Stack

Walkthrough

The documentation expands notification silence concepts, reference semantics, examples, creation methods, filter variables, recursive behavior, and event template variables.

Changes

Notification silence documentation

Layer / File(s) Summary
Silence reference semantics
mission-control/docs/reference/notifications/_silence.mdx
The reference clarifies RFC3339 and date-math time fields, recursive scope, and OR evaluation for filters and selectors.
Silence concepts and usage
mission-control/docs/guide/notifications/concepts/silences.mdx
The guide adds targeting examples, creation methods, matching rules, filter variables, time windows, and recursive behavior.
Notification template variables
mission-control/docs/reference/notifications/_env_vars.mdx
Check-health and config-event templates now document source_event and event_time. Vale spelling checks are scoped around the document.

Merge Risk: 🔵 Low · up to af6ea

The PR adds notification documentation but currently includes invalid field definitions and broad spelling-check suppression, which could make the reference content inaccurate and bypass documentation quality checks. It is mergeable with explicit owner follow-up to correct these localized issues.

@moshloop I've opened a new pull request, #501, to work on those changes. Once the pull request is ready, I'll request review from you.

Expand the source-backed examples and document selector, filter, recursive, and time-range semantics. Keep the silence field and event variable references consistent with the implementation.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Do not disable Vale spelling checks for the full document.

These directives disable the spelling rule for all prose between the first and last lines. Add only project-specific tool names and acronyms to styles/ignore/words-with-suggestions.txt, then remove the document-wide suppression.

As per coding guidelines, add new names of tools and acronyms to styles/ignore/words-with-suggestions.txt.

Also applies to: 502-503

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use valid Fields row definitions in both template sections.

Both new sections omit required and use the unsupported `time.Time` scheme.

  • mission-control/docs/reference/notifications/_env_vars.mdx#L41-L50: Add required to both rows and use a supported scheme representation.
  • mission-control/docs/reference/notifications/_env_vars.mdx#L98-L107: Apply the same row-schema fix.
