weekly-signal-diff

Use when the user wants a weekly structural diff on AI, software, or another fast-moving market. Starts from 10 suggested categories and 30 suggested companies when no watchlist exists, then adapts the scan using Open Brain memory, current priorities, and prior digests. Best for prompts like "run my weekly signal diff", "what changed this week that matters to me", "track this market", or "turn this week's news into structural shifts". Optional live search upgrade: if OpenRouter access is available, prefer the Perplexity Sonar family for fresh web-grounded retrieval with citations.

Quality

Content

85%

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

The body is a well-structured procedural skill with clear sequencing, actionable defaults, explicit quality gates, and clean one-level-deep references. The only soft spot is mild redundancy between the frontmatter triggers and the 'When to Use' list, plus portability notes that slightly pad the token budget.

Suggestions

Trim the 'When to Use' list or fold it into the frontmatter to avoid re-stating the same triggers already in the description.

Shorten 'Notes for Other Clients' to only the portability essentials, since the Open-Brain-tool-name adaptation is already covered in the Process step.

DimensionReasoningScore

Conciseness

The body is mostly efficient procedural prose with no explanations of concepts Claude already knows, but the 'When to Use' section duplicates the frontmatter triggers and 'Notes for Other Clients' adds portability commentary that could be tightened, matching the mostly-efficient-but-could-be-tighter anchor.

2 / 3

Actionability

As an instruction-only skill it gives concrete, specific guidance: an 8-step process, a default output structure with per-item sub-fields, explicit defaults (7-day window), and a 'score before writing' gate; per scoring notes the absence of code is not penalized when guidance is this actionable.

3 / 3

Workflow Clarity

A clearly sequenced 8-step workflow with explicit checkpoints and feedback (e.g. 'If live search is not available... say the diff is source-bounded', 'explicitly label speculation', 'If evidence is thin, say the week was thin'), matching the clear-sequence-with-checkpoints anchor.

3 / 3

Progressive Disclosure

The overview points to two real, clearly-signaled one-level-deep references (starter-universe.md and live-search-upgrade.md), both present and relevant, each invoked conditionally — matching the clear-overview-with-well-signaled-references anchor with no nested chaining.

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.

The description is specific, trigger-rich, and complete: it states concrete actions, natural user phrasings, an explicit 'Use when' trigger, and a clearly differentiated niche. It is concise and free of vague fluff or over-claims.

DimensionReasoningScore

Specificity

Lists multiple concrete actions: 'weekly structural diff', 'adapts the scan using Open Brain memory, current priorities, and prior digests', and bootstrapping from '10 suggested categories and 30 suggested companies' — matching the multiple-specific-actions anchor rather than just naming a domain.

3 / 3

Completeness

Clearly answers both what ('weekly structural diff... adapts the scan using Open Brain memory') and when via an explicit 'Use when the user wants...' clause plus 'Best for prompts like' triggers, satisfying the both-what-and-when anchor.

3 / 3

Trigger Term Quality

Quotes natural user phrasings a user would actually say: 'run my weekly signal diff', 'what changed this week that matters to me', 'track this market', and 'turn this week's news into structural shifts', giving good coverage of natural variations.

3 / 3

Distinctiveness Conflict Risk

The 'weekly structural diff' niche tied to Open Brain memory and Perplexity Sonar retrieval is clearly differentiated and unlikely to fire for unrelated skills, matching the clear-niche-distinct-triggers anchor.
