vcp-screener

Screen S&P 500 stocks for Mark Minervini's Volatility Contraction Pattern (VCP) and detect historical VCPs in a single ticker's price path. Identifies Stage 2 uptrend stocks forming tight bases with contracting volatility near breakout pivot points; in historical single-ticker mode walks a multi-year history and emits every VCP that formed with forward-outcome stats (breakout / stop-hit / timeout). Use when user requests VCP screening, Minervini-style setups, tight base patterns, volatility contraction breakout candidates, Stage 2 momentum stock scanning, or historical VCP pattern study on a specific ticker (e.g. FIX, TSLA).

Quality

Content

76%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 body is highly actionable with copy-paste commands and well-organized references, but the batch workflow lacks explicit validation/verification checkpoints, and there is minor cross-section redundancy. Tightening repetition and adding a verify-output step would lift it further.

Suggestions

Add an explicit validation checkpoint to the workflow (e.g., 'Confirm the timestamped report files exist and check API call count before presenting results; if the script errored, rerun with a smaller universe or check FMP_API_KEY').

Dedupe the reference list — keep it in the 'Resources' section only, or reference it once in Step 2 rather than restating all three files in both places.

Consider moving the Advanced Tuning parameter table into references/ (e.g. scoring_system.md or a tuning reference) to keep the main body a lean overview.

DimensionReasoningScore

Conciseness

Mostly lean and assumes Claude's competence (no basic-concept padding), but has minor redundancy — references appear in both 'Step 2' and the 'Resources' section, and output filenames are described in both the historical section and the 'Output' section — so it sits just below the 'every token earns its place' anchor.

4 / 5

Actionability

Fully copy-paste-ready bash commands cover the common cases (default, custom universe, full S&P 500, strict mode, historical single-ticker, advanced tuning) and parameter tables give defaults/ranges, matching the top anchor for executable guidance.

5 / 5

Workflow Clarity

A clear 4-step sequence with a Prerequisites section is present, but this is a batch/screening operation and there is no explicit validation or verify-then-retry checkpoint (e.g., confirm reports generated / handle API failures before presenting), which the rubric caps at 3 for batch ops lacking validation.

3 / 5

Progressive Disclosure

Good structure with one-level-deep, clearly signaled references (vcp_methodology.md, scoring_system.md, fmp_api_endpoints.md — all verified real files) and a Resources section, though the large inline parameter/tuning tables could arguably live in a reference file.

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 voice, concrete actions, comprehensive natural trigger terms, and an explicit 'Use when' clause covering both screening and historical-study modes. It clearly distinguishes the skill and would reliably fire on the right requests.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Screen S&P 500 stocks for...VCP', 'detect historical VCPs in a single ticker's price path', 'Identifies Stage 2 uptrend stocks forming tight bases with contracting volatility near breakout pivot points', 'walks a multi-year history and emits every VCP...with forward-outcome stats' — giving comprehensive coverage of capabilities.

5 / 5

Completeness

Explicitly answers both what ('Screen S&P 500 stocks...detect historical VCPs...') and when ('Use when user requests VCP screening, Minervini-style setups...') with concrete trigger phrases, matching the top anchor.

5 / 5

Trigger Term Quality

Comprehensive natural-term coverage with synonyms: 'VCP screening, Minervini-style setups, tight base patterns, volatility contraction breakout candidates, Stage 2 momentum stock scanning, or historical VCP pattern study', plus concrete ticker examples (FIX, TSLA) users would naturally name.

5 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (Minervini VCP screener with historical single-ticker mode) with distinct, domain-specific triggers and minimal overlap risk with other skills.
