The body is lean and table/bullet-driven, never explaining concepts Claude already knows; every line earns its place, matching the 'lean and efficient' anchor rather than the padded score 2 example.

As an instruction-only skill it provides concrete, actionable guidance — a specific severity table, default routing rules ('interrupt for release, CI, security, and owner-blocking events'), and a copy-paste-ready output template; per the rubric, absence of code is not penalized when guidance is actionable.

A clear five-step workflow (Inventory, Decide interruption, Collapse duplicates, Design, Return action-biased design) plus an explicit Event Pipeline gives a well-sequenced process; this is design work rather than destructive/batch operations, so the missing-validation cap does not apply.

Content is well-organized into clear sections but is a single monolithic ~180-line file with no bundle files (references/, scripts/, assets/ are empty) and no one-level-deep references, matching the score 2 anchor where content that could be separate stays inline.

Lists multiple concrete actions — 'alert routing, deduplication, escalation, or inbox collapse' — across named surfaces (GitHub, Linear, desktop alerts, hooks), matching the 'multiple specific concrete actions' anchor rather than the domain-only score 2.

Explicitly answers both what ('Operate notifications as one ECC-native workflow...') and when via the 'Use when the real problem is alert routing, deduplication, escalation, or inbox collapse' clause, matching the score 3 anchor; not capped at 2 because the trigger clause is present.

Uses natural user-facing terms ('alert routing, deduplication, escalation, inbox collapse') a user would actually say, giving good coverage rather than the partial score 2 example ('Works with PDF files').

Carves a clear ECC-native notification-consolidation niche with distinct triggers, unlikely to fire for the wrong skill; matches the score 3 'clear niche' anchor rather than the overlapping score 2 example.
