cot-contrarian-detector

Detect crowded speculative positioning in CFTC futures markets (COT report analysis) to find contrarian setups using Jason Shapiro's methodology. Screens large-speculator ("non-commercial") net positioning across 65 futures markets (indices, rates, FX, metals, energy, crypto) via the FMP Commitment of Traders API, computes a 3-year and 26-week COT Index per market, and classifies extremes as CROWDED_LONG / CROWDED_SHORT. Use when the user asks about COT report analysis, crowded positioning, "who is trapped", speculative positioning extremes, contrarian futures setups, or wants to run Jason Shapiro-style analysis. This skill automates crowding DETECTION only (step 1 of 5) — it does not generate trade signals by itself.

Quality

Content

72%

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

The body is actionable and well-structured with strong progressive disclosure, but it could be tightened (the bilingual trigger block and thesis prose add length) and the batch workflow lacks an explicit validation checkpoint.

Suggestions

Remove the duplicate Japanese trigger listing (or move it to a reference) since trigger guidance already lives in the description; trim the 'Core thesis' rationale to one line.

Add an explicit validation step between Phase 1 and Phase 2, e.g. 'Review the skipped list and confirm run_context.data_date is recent before presenting the report.'

Consider moving the Shapiro thesis detail into references/shapiro-methodology.md and keeping the Overview to a single orienting sentence.

DimensionReasoningScore

Conciseness

Mostly efficient for a complex skill, but the bilingual English/Japanese trigger block duplicates guidance already in the description and the 'Core thesis (Shapiro)' paragraph is partly conceptual rationale that could be tightened.

2 / 3

Actionability

Provides concrete, copy-paste-ready commands with flags across three usage modes, explicit output file paths, and precise classification thresholds (>=90, <=10).

3 / 3

Workflow Clarity

A clear 3-phase sequence with numbered Shapiro steps is present, but the batch operation (up to 65 API calls) lacks an explicit validation checkpoint (e.g., review the 'skipped' list or verify 'data_date' before presenting), which caps it at 2.

2 / 3

Progressive Disclosure

SKILL.md is a well-organized overview with one-level-deep references clearly signaled via a 'Resources' and 'When to Load References' section; all referenced files and scripts exist and content is appropriately split.

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, complete, and distinctive. It cleanly answers what the skill does and when to invoke it, and sets an explicit scope boundary to avoid misuse.

DimensionReasoningScore

Specificity

Lists multiple concrete actions (detect crowded positioning, screen 65 markets, compute 3-year/26-week COT Index, classify CROWDED_LONG/CROWDED_SHORT) rather than vague language.

3 / 3

Completeness

Explicitly answers both what it does and when to use it via a clear 'Use when...' clause, with an explicit scope boundary ('DETECTION only, step 1 of 5').

3 / 3

Trigger Term Quality

Strong natural-term coverage ('COT report analysis', 'crowded positioning', 'who is trapped', 'contrarian futures setups', 'Jason Shapiro-style analysis') that users would actually say.

3 / 3

Distinctiveness Conflict Risk

Niche is distinct (CFTC COT contrarian detection via Shapiro methodology) with specific triggers and a scope cap, making conflict with other skills unlikely. Voice is third person throughout.
