Conciseness

The body is largely lean and high-value (Dynatrace-specific pipeline behavior, 'Common wrong guess that does NOT work: events.ingest', tight tables), but the 'Threshold maths for a 3-location test: 1 location failing → avg 0.67 (no alert at 0.5 threshold); 2 failing → avg 0.33' paragraph spells out arithmetic Claude can derive from the preceding table. This fits the 4 anchor (efficient, minor over-explanation that could be trimmed) rather than 5 (every token earns its place).

Actionability

Guidance is fully executable and copy-paste ready: a complete curl POST with real field values ('test.run.availability': 1, 'dt.security_context': 'team-checkout'), 'Expected response: HTTP 200 (empty body)', a runnable DQL verification query, and precise constraints like 'must be integer 1 or 0, not a string'. This matches the 5 anchor (specific examples covering the common cases); it is not 4 because no key detail is missing for the primary use case.

Workflow Clarity

The sequence is clear and validation checkpoints are present — prerequisite callout ('The ingest endpoint must be created in OpenPipeline before sending events'), the expected HTTP 200 response, and a dedicated 'Verify in Grail' DQL section. However, there is no error-recovery feedback loop (e.g. what to check on a 401/404), which the 5 anchor requires; the Key Constraints section is preventive rather than a recovery path, so this sits between the 4 and 5 anchors at 4.

Progressive Disclosure

The body is a clean overview (quick start, key constraints, verification) with the full schema, extended examples, Java DTOs, and DQL reference correctly deferred to references/event-ingestion.md — a real, verified file that is self-contained (internal anchors only, no further file references, so exactly one level deep). The pointer is well-signaled twice with an explicit content inventory ('Full event schema, step events, extended examples with error fields and CI metadata, Java DTO shapes, and DQL queries'), matching the 5 anchor.

Specificity

The description lists multiple concrete capabilities: '3rd-party test and monitor result ingestion into Dynatrace Grail via the platform events ingest API (platform/ingest/custom/events/)', 'token scope, full event schema for external_test_run and external_test_step', 'curl and Java DTO examples, and DQL verification'. This matches the 5 anchor (multiple specific concrete actions, comprehensive coverage); it is not 4 because coverage spans ingestion, auth, schema, examples, and verification with no notable gaps.

Completeness

Both questions are answered explicitly: 'what' via 'ingestion into Dynatrace Grail via the platform events ingest API' with enumerated coverage areas, and 'when' via both 'Use when sending external synthetic test outcomes, CI monitor data, or third-party check results' and a dedicated concrete 'Triggers:' list. This is the 5 anchor verbatim in structure; a 4 would require the 'when' to be less explicit than it is here.

Trigger Term Quality

An explicit trigger list gives six natural phrases users would say: 'ingest test results', 'send monitor results', 'third party monitor', 'external test ingestion', 'send synthetic results to Grail', 'external test run event schema'. These include natural variations and the API path, matching the 5 anchor's comprehensive synonym coverage; nothing on the 4 anchor's 'a few natural terms missing' condition applies.

Distinctiveness Conflict Risk

The niche is precise (one API, two event types) and conflict risk is actively reduced by negative boundary guidance: 'Not for Dynatrace-native Synthetic Monitoring browser/HTTP checks, or RUM (use dt-obs-frontends)' plus routing to 'dt-upgrade' for the deprecated v1 API. Clear niche with distinct triggers and minimal conflict risk is the 5 anchor; 4 would require some residual overlap with closely related skills, which the exclusions already resolve.
