Conciseness

The body is lean and well compressed — the 6-component table, regime list, and comparison table convey dense information without padding, and it assumes Claude's competence throughout. It falls short of 5 due to minor redundancy: the FMP API key guidance appears in both "Prerequisites" and "Script Arguments", and the three reference documents are listed twice (Workflow step 1/4 and the "Resources" section).

Actionability

The workflow gives mostly executable guidance: a concrete install command, a ready-to-run `uv run python3 skills/macro-regime-detector/scripts/macro_regime_detector.py --output-dir reports/` invocation, and documented CLI options. It is not 5 because the install step targets `skills/macro-regime-detector/requirements.txt`, a file that does not exist anywhere in the bundle (only SKILL.md, references/, and scripts/ are present), so the prerequisite step as written would fail.

Workflow Clarity

The 4-step workflow (load references → run script → read report → present findings) is clearly sequenced and includes an explicit failure-mode checkpoint: "The detector fails closed and writes no report when none of its six components has usable data. Do not treat a missing report or non-zero exit as a valid low-transition regime." It stops short of 5 because there is no recovery guidance for that failure (e.g., what to check or retry), only a warning not to misread it.

Progressive Disclosure

SKILL.md is a clean overview: methodology and interpretation detail are pushed to `references/regime_detection_methodology.md`, `references/indicator_interpretation_guide.md`, and `references/historical_regimes.md` — all of which exist in the bundle — referenced one level deep and clearly signaled both in the workflow and in a Resources section. No inlining of content that belongs in separate files.

Specificity

The description lists multiple concrete capabilities — "Analyze RSP/SPY concentration, yield curve, credit conditions, size factor, equity-bond relationship, and sector rotation" — and names all five output states (Concentration, Broadening, Contraction, Inflationary, Transitional), giving comprehensive and specific coverage. It is not the 4 anchor because nothing significant is missing: the inputs, the analysis actions, and the classification outputs are all explicit.

Completeness

It explicitly answers both questions: what it does ("Detect structural macro regime transitions (1-2 year horizon) using cross-asset ratio analysis...") and when to use it ("Run when user asks about macro regime, market regime change, structural rotation, or long-term market positioning"). This matches the anchor-5 example structure of concrete capabilities followed by explicit trigger phrases; there is no weak 'when' that would drop it to 4.

Trigger Term Quality

"Run when user asks about macro regime, market regime change, structural rotation, or long-term market positioning" provides good natural phrasing users would actually say. Not a 5 because common synonyms like "market cycle", "regime shift", or "broadening/rotation trade" are missing, leaving a few natural trigger variations uncovered.

Distinctiveness Conflict Risk

"RSP/SPY concentration", "yield curve", "HYG-style credit conditions", and named regime states carve out a clear niche with distinct trigger phrases ("macro regime", "market regime change"), minimizing conflict risk with generic market-analysis skills. It sits above the 4 anchor because the trigger terms are specific to regime detection rather than merely naming file types or broad domains.
