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

72%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.

The content is a well-structured procedural skill with good progressive disclosure and mostly actionable guidance, but its batch/automated workflow lacks explicit validation feedback loops, capping workflow clarity. Minor repetition across the description and 'Notes for Other Clients' section could be trimmed for token efficiency.

Suggestions

Add an explicit validation/verification checkpoint to the workflow — e.g., after producing the diff, verify it is captured back to Open Brain correctly and re-run capture on failure — to lift workflow_clarity above the batch-operation cap of 3.

Trim the 'Notes for Other Clients' section and the repeated Perplexity Sonar advice (already stated in the description) to remove redundant tokens and improve conciseness.

Make the Open Brain tool usage more concrete with example call shapes or a short template for the digest capture, reducing the abstraction in the actionability guidance.

DimensionReasoningScore

Conciseness

The body is procedural and assumes Claude's competence without explaining known concepts, but the 'Notes for Other Clients' section and the repeated Perplexity Sonar advice (already in the description) are minor instances of over-explanation that could be trimmed.

4 / 5

Actionability

As an instruction-only skill it gives concrete guidance — explicit structural questions, a named default output structure, and numeric targets (3-7 shifts, last 2-4 digests) — but Open Brain tool calls remain abstracted rather than fully specified, leaving minor gaps.

4 / 5

Workflow Clarity

The eight-step sequence is clear and well-ordered, but this batch/automated operation (writing a weekly digest back to Open Brain) lacks explicit validation checkpoints or verify-then-retry feedback loops, capping workflow clarity at 3 per the batch-operations guideline.

3 / 5

Progressive Disclosure

The body is a clear overview that points to two real one-level-deep reference files (starter-universe.md, live-search-upgrade.md) via inline markdown links at the points of need, with starter data and live-search details appropriately split out rather than inlined.

Description

100%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.

The description is exemplary: third person, concise yet comprehensive, with an explicit 'Use when' clause and four concrete natural-language trigger phrases. It cleanly answers both what the skill does and when to invoke it with low conflict risk.

DimensionReasoningScore

Specificity

Names multiple concrete actions — 'weekly structural diff', 'Starts from 10 suggested categories and 30 suggested companies', 'adapts the scan using Open Brain memory', and 'prefer the Perplexity Sonar family' — matching the comprehensive-coverage anchor.

5 / 5

Completeness

Both what and when are explicit: an opening 'Use when' clause, the concrete behavior ('Starts from… adapts the scan…'), and trigger phrases — clearly matching the anchor that requires concrete trigger phrases for both.

5 / 5

Trigger Term Quality

An explicit 'Best for prompts like' clause gives four natural user phrases ('run my weekly signal diff', 'what changed this week that matters to me', 'track this market', 'turn this week's news into structural shifts'), providing comprehensive natural trigger coverage.

5 / 5

Distinctiveness Conflict Risk

The niche is specific (weekly structural market diff driven by Open Brain memory and Perplexity Sonar retrieval) with distinct triggers, giving minimal conflict risk with other skills.
