Quality

Content

76%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

An actionable, well-structured API reference with executable examples and no filler, hindered mainly by a multi-step workflow ('adding a new notification type') that lacks an explicit validation checkpoint. Splitting the verbose field reference into a bundled file would further improve progressive disclosure.

Suggestions

Add an explicit verification step to the 'Adding a new notification type' workflow (e.g. 'Run `python manage.py test notifications` and confirm the new type renders an icon in the menu') to raise workflow clarity.

Tighten the Priority paragraph by trimming the editorializing ('This is intentionally intrusive', 'Overusing critical will train users to ignore notifications entirely') to the concrete behavioral rule and the 'when in doubt, use normal' default.

Consider moving the full NotificationData required/optional field tables into a references/ file (e.g. REFERENCE.md) and linking to it from a short inline summary, to push progressive disclosure toward one-level-deep external references.

DimensionReasoningScore

Conciseness

Dense, system-specific reference that assumes Claude's competence and explains no generic concepts; the Priority paragraph's editorializing ('Overusing critical will train users to ignore notifications entirely') and slight overlap between the intro and the description could be trimmed, keeping it just below fully lean.

4 / 5

Actionability

Copy-paste ready facade import and create_notification call plus a working test mock, with concrete field/type/target tables and exact file paths covering the common cases.

5 / 5

Workflow Clarity

The 'Adding a new notification type' workflow has a clear 4-step sequence with exact paths, but contains no validation or verification checkpoint (no 'run tests' / 'verify migration created'), which caps it at 3 per the missing-validation guidance.

3 / 5

Progressive Disclosure

Well-organized with clear section headers and no nested references, all content inline; at ~125 lines the full NotificationData field reference could arguably be externalized, and the under-50-line simple-skill exception does not apply, so it sits at good-but-not-fully-split.

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A well-crafted description that clearly states both what the skill does and when to use it, with concrete enumerated trigger scenarios and a distinct PostHog-specific niche. Minor synonym coverage is the only thing keeping trigger term quality from the top.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — sending real-time in-app notifications, integrating them into a feature, wiring up a notification source (alerts, comments, approvals, pipelines, issues), and choosing target type and priority — giving comprehensive coverage; voice is third-person/imperative with no first/second-person penalty.

5 / 5

Completeness

Explicitly answers 'what' ('send real-time in-app notifications from PostHog backend code') and 'when' with multiple concrete trigger phrases, satisfying the top anchor.

5 / 5

Trigger Term Quality

Strong natural keywords users would say ('notifications', 'alerts', 'comments', 'approvals', 'pipelines', 'issues'), but it lacks common synonyms (e.g. 'messages', '@mention') and there are no file extensions, so it sits just below comprehensive.

4 / 5

Distinctiveness Conflict Risk

A clear niche (PostHog backend in-app notifications) with specific, distinct triggers and minimal overlap risk with other skills.
