finviz-screener

Build and open FinViz screener URLs from natural language requests. Use when user wants to screen stocks, find stocks matching criteria, filter by fundamentals or technicals, or asks to open FinViz with specific conditions. Supports both Japanese and English input (e.g., "高配当で成長している小型株を探したい", "Find oversold large caps with high ROE").

Quality

Content

81%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 skill body is highly actionable with executable commands, clear bilingual filter mappings, and six practical recipes, supported by real bundle files. Its main weakness is mild verbosity — the inline concept-mapping table and recipe count could be trimmed and deferred to the reference — and the absence of an explicit filter-validation feedback loop.

Suggestions

Trim or move the ~50-row Common Concept Mapping table into references/finviz_screener_filters.md, keeping only 5-10 representative rows inline so the overview stays lean.

Add an explicit validation/retry checkpoint in Step 4 (e.g., if the script rejects a filter code, re-read the reference, correct the token, and re-run) to lift workflow clarity.

Consider condensing the six Usage Recipes to three with a pointer to a recipes reference file, reducing duplicated filter-code tables.

DimensionReasoningScore

Conciseness

The body is largely efficient — mapping tables, executable command blocks, and recipes earn their place — but the ~50-row concept-mapping table and six full recipes add length that borders on padded relative to a pointer-style overview. Not a 5 because some table rows and recipe detail could be deferred to the reference file.

4 / 5

Actionability

Provides copy-paste-ready `python3 scripts/open_finviz_screener.py` invocations with real flags, a filter-to-code mapping table, and complete recipe filter sets that cover the common cases. Fully executable guidance.

5 / 5

Workflow Clarity

The five-step workflow (load reference → interpret → present for confirmation → execute → report) is clearly sequenced with an explicit user-confirmation checkpoint before execution. Held at 4 rather than 5 because there is no explicit validate/retry feedback loop for invalid filter codes, and the operation is only semi-batch (opens a browser) so the destructive-batch cap does not apply.

4 / 5

Progressive Disclosure

Good one-level-deep structure: the body points to `references/finviz_screener_filters.md` (verified present) and `scripts/open_finviz_screener.py` (verified present) with a Resources section, and keeps quick-start material inline. Not a 5 because the large inline concept-mapping table duplicates content that arguably belongs entirely in the reference file rather than being split cleanly.

Description

96%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 strong, concise, and bilingual, clearly stating both capability and trigger conditions with concrete example phrases. Minor overlap risk exists with sibling stock-screening skills due to a few generic phrases, but it is otherwise exemplary.

DimensionReasoningScore

Specificity

Names the domain (FinViz screener URLs) and lists multiple concrete actions — 'Build and open', 'screen stocks', 'find stocks matching criteria', 'filter by fundamentals or technicals' — matching the comprehensive-coverage anchor.

5 / 5

Completeness

Explicitly answers both 'what' ('Build and open FinViz screener URLs from natural language requests') and 'when' ('Use when user wants to screen stocks...') with concrete trigger phrases, matching the top anchor.

5 / 5

Trigger Term Quality

Covers natural user phrasings in two languages — 'screen stocks', 'find stocks matching criteria', 'filter by fundamentals or technicals', and concrete Japanese/English example triggers — giving comprehensive keyword coverage with synonyms.

5 / 5

Distinctiveness Conflict Risk

The FinViz-specific niche and bilingual trigger examples make it clearly distinct with minimal conflict risk; held at 4 rather than 5 because broad phrases like 'find stocks matching criteria' could loosely overlap with other stock-screening skills.
