Conciseness

The body is efficient — executable commands, dense operational caveats (budget trimming, timing fallback) that Claude could not infer, and no padding with basic-concept explanations. However, the opening paragraph and the 'When to Use' bullets restate the frontmatter description almost verbatim, so a minor trim is possible; this matches the score-4 anchor ('efficient; minor instances... that could be trimmed') rather than score 5, where every token would earn its place.

Actionability

Both common cases are covered with copy-paste-ready commands: Mode A default and custom-parameter invocations, Mode B with --candidates-json and --min-grade, plus env-var setup, concrete score bands ('85+', '70-84'), and named output files. This matches the score-5 anchor; it is not score 4 because the examples span the common cases with complete, executable syntax.

Workflow Clarity

Steps 1-4 are clearly sequenced, and there is a real validation checkpoint — 'If Mode A is used anyway and the script reports budget trimming or non-US symbols, mark PEAD output as degraded and treat it as manual-review only' — plus the timing_unknown_count/timing_candidates_total visibility note. Minor gaps remain: no explicit instruction to verify the script exited successfully or that output files were created before presenting results, so it fits score 4 rather than 5.

Progressive Disclosure

SKILL.md is a concise overview that delegates theory and trade rules to two real, one-level-deep reference files ('references/pead_strategy.md - PEAD theory', 'references/entry_exit_rules.md - Entry, exit, and position sizing rules'), signaled both in the workflow steps and in a Resources section, with the referenced scripts present in the bundle. This matches the score-5 anchor (clear overview, well-signaled one-level-deep references, appropriate split).

Specificity

The description lists multiple concrete actions — 'Screen post-earnings gap-up stocks for PEAD patterns', 'Analyzes weekly candle formation to detect red candle pullbacks and breakout signals', and 'Supports two input modes - FMP earnings calendar (Mode A) or earnings-trade-analyzer JSON output (Mode B)' — covering screening, analysis, detection, and input handling comprehensively in third-person voice. This matches the score-5 anchor (multiple specific concrete actions, comprehensive coverage); it is not score 4 because there is no meaningful gap in what the skill does.

Completeness

Both 'what' (three sentences of concrete capabilities) and 'when' ('Use when user asks about PEAD screening, post-earnings drift, ...') are explicitly stated with concrete trigger phrases, exactly matching the score-5 anchor. Not score 4, because the 'when' clause is fully explicit rather than merely present.

Trigger Term Quality

The 'Use when' clause covers natural trigger phrases with synonyms: 'PEAD screening, post-earnings drift, earnings gap follow-through, red candle breakout patterns, or weekly earnings momentum setups', plus the full expansion 'Post-Earnings Announcement Drift' and 'earnings-trade-analyzer JSON output' for Mode B. This is comprehensive natural-term coverage for the domain, matching the score-5 anchor rather than score 4 ('a few natural terms missing') since both the acronym and its expansion plus five user-facing phrases are present.

Distinctiveness Conflict Risk

The description occupies a clear niche (PEAD/post-earnings drift screening with weekly candle analysis) and its triggers — PEAD, red candle breakout, earnings momentum — are distinct terms unlikely to fire for unrelated skills. The reference to sibling skill 'earnings-trade-analyzer' describes a deliberate input relationship, not overlapping triggers, so it does not raise conflict risk above the score-5 anchor.
