Conciseness

The body is dense and assumes competence — no padding, no explanation of concepts Claude already knows, and the JSON example documents the output contract rather than over-teaching. It is not a 5 because the double-counting invariant is explained twice at length ("How It Works" bullet and "Key Principles" 1–2), and "Pure calculation — no API key required" repeats the description. It is not a 3 because these are minor trims, not whole unnecessary sections.

Actionability

Step 1 gives a fully executable, copy-paste-ready command with realistic flags ("python3 skills/weekly-performance-digest/scripts/generate_weekly_digest.py --state-dir state/theses --from-date 2026-06-13 --to-date 2026-06-20 --output-dir reports/ -v"), documents all defaults, names the exact output files, and shows the complete JSON output schema. Coverage of the common case (default trailing-7-day run) is explicit.

Workflow Clarity

A clear three-step sequence (run → read report → optional downstream) with concrete commands, flag defaults, and explicit edge-case behavior ("An empty week still produces a valid report with zeroed metrics (exit code 0)"). It is not a 5 because there is no explicit validation/checkpoint step (e.g., confirming the output files were written or inspecting summary counts before interpreting), though as a read-only descriptive skill it carries little risk; it is not a 3 because the sequence is complete and unambiguous with implicit checkpoints.

Progressive Disclosure

The body is a well-organized overview that moves detail to one-level-deep, verified bundle files: "scripts/generate_weekly_digest.py — digest generator (JSON + Markdown)" and "references/weekly-digest-metrics.md — metric formulas and interpretation", both of which exist in the bundle and match their descriptions. Inline content (workflow, output schema, core invariants) is appropriately kept in SKILL.md, and navigation via the Resources section is clear.

Specificity

"Generate a weekly performance summary from closed trader-memory-core theses — win rate, expectancy, profit factor, R-multiple, MAE/MFE, and win/loss pattern analysis by source skill, exit reason, thesis type, sector, and mechanism" lists multiple specific concrete capabilities with comprehensive coverage of the digest's metric and breakdown dimensions. It is not a 4 because coverage is thorough rather than having minor gaps, and it uses proper third-person voice ("Generate").

Completeness

The "what" is clearly and concretely answered (metrics, breakdown dimensions, local calculation), but there is no "Use when..." clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It is not a 2 because the "what" is fully explicit rather than vague; it is not a 4 because no temporal or situational usage trigger is stated at all.

Trigger Term Quality

Good natural keyword coverage — "weekly performance summary", "win rate", "expectancy", "profit factor", "closed" trades, "trader-memory-core" — phrases a user reviewing trading performance would plausibly say. It falls short of 5 because common synonyms and variations like "trading review", "trade journal", "P&L review", or "postmortem" are absent, leaving a few natural entry points uncovered.

Distinctiveness Conflict Risk

"from closed trader-memory-core theses" plus the distinctive metric set (R-multiple, MAE/MFE, pattern analysis by exit reason and mechanism) carves out a clear niche with minimal overlap risk against generic reporting or single-trade review skills. It is not a 4 because the domain anchoring and unique metric vocabulary make confusion with any neighboring skill unlikely.
