blog-decay

Detect content decay from Google Search Console exports by comparing current and previous page performance, flagging quarter-over-quarter traffic drops, dropped pages, and refresh, consolidate, prune, or query-shift actions. Use when the user says "/blog decay", "content decay", "traffic drop", "QoQ decline", "GSC decay", or "refresh declining posts".

Quality

Content

100%

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

The body is tight and actionable: concrete commands, input-format specs, severity and action decision tables, and validation guidance, all well-structured with one-level cross-references. Its only real weakness is packaging — the core referenced scripts are not shipped in this skill package.

Suggestions

Ship the referenced scripts/ directory: the body's primary command ('python3 scripts/content_decay.py ...') points to scripts/content_decay.py, but no scripts/ bundle directory exists in this skill package, so the command is not executable as shipped.

Verify the cross-skill path 'skills/blog-google/scripts/run.py' resolves in the deployment context, or document that blog-google must be installed separately, so the Optional Live GSC Export workflow is runnable.

Dimension	Reasoning	Score
Conciseness	The body is lean and assumes competence — it never explains what GSC, redirects, or QoQ mean, and every section (severity table, action table, input format) earns its tokens rather than padding concepts Claude already knows.	3 / 3
Actionability	Gives fully concrete, copy-paste-ready commands with options ('python3 scripts/content_decay.py current.json previous.json --threshold 0.30'), specifies the accepted input shapes, and supplies decision tables — matching the executable level-3 anchor.	3 / 3
Workflow Clarity	Two sequenced workflows (offline, live) with explicit validation checkpoints ('confirming identical filters, sufficient row limits, matching dimensions, and URL inspection'; 'only after checking indexation, canonical status, query loss...') provide clear sequence and checklists; the task is analytical rather than destructive, so no feedback-loop cap applies.	3 / 3
Progressive Disclosure	A single well-organized SKILL.md with clearly labeled sections and one-level-deep cross-references (Cross-references → blog-google, blog-rewrite) and no nested reference chains, matching the clear-overview level-3 anchor.	3 / 3
	Total	12 / 12 Passed

Description

100%

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 strong description: it names concrete capabilities, supplies an explicit 'Use when' trigger clause with natural phrasing, and carves out a distinct niche. No vague fluff or over-claims, and it stays in third person throughout.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'flagging quarter-over-quarter traffic drops, dropped pages, and refresh, consolidate, prune, or query-shift actions' — matching the anchor for comprehensive specific actions rather than the partial level-2 example.	3 / 3
Completeness	Explicitly answers both what (detect decay by comparing current vs previous GSC exports and flagging drops/actions) and when via an explicit 'Use when the user says...' clause, satisfying the level-3 anchor.	3 / 3
Trigger Term Quality	Provides natural trigger phrases a user would say — "/blog decay", "content decay", "traffic drop", "refresh declining posts" — giving good coverage rather than just a few relevant keywords.	3 / 3
Distinctiveness Conflict Risk	Clear niche (blog content decay from Search Console exports) with distinct triggers unlikely to collide with other skills; uses correct third-person voice so no specificity penalty.	3 / 3
	Total	12 / 12 Passed
