Conciseness

The body is mostly efficient rule-driven prose, but contains real duplication: the 'Sample Triggers' section repeats the four Input Validation examples verbatim, Hard Rules 3 and 14 both forbid presenting disproportionality signals as incidence/absolute risk, and Hard Rules 10 and 13 overlap heavily. This fits the 3 anchor (mostly efficient but could be tightened) rather than 4, since the repetition is substantive enough to remove whole blocks.

Actionability

For an instruction-only planning skill the guidance is concrete: exact pattern and config selection tables, named output sections A–J with required fields, minimum retrieval counts ('2–4 drug/safety-background references'), an exact disclaimer line to reproduce, and per-reference format rules. Fits the 4 anchor (mostly executable guidance with minor gaps); not 5 because several directives remain abstract ('Explain the logic of each decision') and concrete templates are deferred to reference files.

Workflow Clarity

The 'Execution — 7 Steps (always run in order)' section gives a clear sequence with an explicit pre-output validation checkpoint (Step 5 dependency consistency check) and a fix loop ('If any dependency inconsistency is found, revise the plan before outputting'), plus input validation with a stop-and-redirect and a hard-rules checklist. This matches the 5 anchor (explicit validation steps, feedback loops, checklists).

Progressive Disclosure

Eight '→' links are well-signaled at each point of need, all point to real files in references/, and are exactly one level deep with no nested references inside the bundle files; the body keeps only overview-level content while details are split into appropriately scoped files. This matches the 5 anchor (clear overview with well-signaled one-level-deep references, easy navigation).

Specificity

The description lists multiple concrete actions — 'Generates... study designs', 'signal detection', 'subgroup analysis', 'onset/seriousness characterization', 'conservative label-gap interpretation' — covering the skill's full module set in correct third-person voice. It matches the 5 anchor (multiple specific concrete actions, comprehensive coverage) rather than 4, since no module category is missing.

Completeness

The 'what' is clear and detailed, but there is no 'Use when...' clause or equivalent explicit trigger guidance, which the judging guidelines cap at 3. It fits the 3 anchor (clear 'what', 'when' missing or only weakly implied) rather than 4, which would require an explicit 'when' clause.

Trigger Term Quality

'FAERS', 'pharmacovigilance', 'signal detection', and 'safety' are natural domain keywords a user would say, but common variants like 'adverse events', 'post-marketing surveillance', and 'drug safety' are absent. Good coverage with a few natural terms missing fits the 4 anchor, below 5 (which requires comprehensive synonym coverage) and above 3 (which implies noticeably sparser keywords).

Distinctiveness Conflict Risk

'One-drug whole-profile safety mapping' carves a specific niche with distinct triggers, but the broad lead 'FAERS pharmacovigilance study designs' overlaps with closely related sibling skills (e.g., comparative FAERS designs referenced in the body). Mostly distinct with minor overlap risk fits the 4 anchor rather than 5.
