Discovery
40%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
The description identifies a clear niche (RSS/Atom feed monitoring via blogwatcher CLI) which makes it distinctive, but it is too terse. It lacks a 'Use when...' clause and doesn't enumerate specific capabilities beyond 'monitor for updates', making it harder for Claude to know precisely when to select this skill.
Suggestions
Add a 'Use when...' clause with trigger terms like 'Use when the user wants to track blog updates, subscribe to RSS feeds, check for new posts, or manage feed subscriptions'.
List more specific actions the skill supports, such as 'add/remove feeds, check for new posts, list tracked blogs, configure update intervals'.
Include common user-facing synonyms like 'news feeds', 'subscribe', 'new posts', 'feed reader' to improve trigger term coverage.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (blogs, RSS/Atom feeds) and one action (monitor for updates), and mentions the specific tool (blogwatcher CLI), but doesn't list multiple concrete actions like adding feeds, filtering, configuring alerts, etc. | 2 / 3 |
Completeness | Describes what the skill does (monitor blogs and feeds) but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. Per the rubric, a missing 'Use when...' clause caps completeness at 2, and the 'what' portion is also thin, warranting a 1. | 1 / 3 |
Trigger Term Quality | Includes relevant keywords like 'blogs', 'RSS', 'Atom', 'feeds', and 'blogwatcher' which users might naturally say, but misses common variations like 'subscribe', 'news feeds', 'feed reader', 'new posts', or 'syndication'. | 2 / 3 |
Distinctiveness Conflict Risk | The combination of RSS/Atom feeds, blog monitoring, and the specific 'blogwatcher CLI' tool creates a clear niche that is unlikely to conflict with other skills. | 3 / 3 |

Implementation
87%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-crafted, concise skill that provides all necessary information to use the blogwatcher CLI effectively. The concrete commands and example outputs make it highly actionable. The only minor weakness is that the common commands could be presented as a suggested workflow sequence rather than an unordered list.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Every line serves a purpose. No unnecessary explanations of what RSS feeds are or how Go works. The content is lean and assumes Claude's competence. | 3 / 3 |
Actionability | Provides fully concrete, copy-paste ready commands for every common operation (add, list, scan, read, remove). The install command and example outputs make this immediately executable. | 3 / 3 |
Workflow Clarity | Commands are listed clearly but presented as a flat list rather than a sequenced workflow. For a monitoring tool, a natural workflow (add → scan → articles → read) is implied but not explicitly sequenced. However, this is a simple tool without destructive/batch operations, so the gap is minor. | 2 / 3 |
Progressive Disclosure | This is a simple, single-purpose skill under 50 lines with no need for external references. The content is well-organized with clear sections (install, quick start, commands, example output, notes) and appropriately self-contained. | 3 / 3 |
Total | 11 / 12 Passed |
