Conciseness

The body is dense and operational — discovery commands, exact config values, FAIL conditions — with nearly every token earning its place; padding is limited to a few explain-heavy asides ("RMT only collapses duplicates on background merge (never guaranteed at query time)... e.g. the slack_active_days = 42 incident" and the long inline fix template in Check 7). This fits anchor 4 ('efficient; minor instances of over-explanation that could be trimmed') better than anchor 5, since some rationale could be moved out or shortened without loss.

Actionability

Concrete, executable guidance dominates: `find src/ingestion/silver -name "*.sql" -not -path "*disabled*"`, grep patterns, exact expected config strings, a runnable audit script (`audit_rmt_read_dedup.py`), and a literal output template. It falls short of anchor 5 only because key references are unresolvable as written — "Read all 5 spec docs (DESIGN.md + 4 ADRs)" gives no paths, and the architecture.md link is a fragile relative path — leaving minor gaps the model must fill.

Workflow Clarity

"How to run" gives a clear numbered sequence (read specs → run 8 checks → per-check PASS/FAIL with paths/lines → summarize → suggest minimal fixes) with explicit checkpoints ("Refuse to report PASS without having read each spec doc this turn"; the deterministic script plus "confirm each by reading" loop in Check 8) and an output-format checklist. It sits at anchor 4 rather than 5 because the first step's inputs (which 5 spec docs, located where) are ambiguous, a minor validation gap.

Progressive Disclosure

No bundle files (references/, scripts/, assets/) exist, and the body correctly externalizes the rules to one clearly signaled one-level-deep source (architecture.md) while keeping the operational checks inline; section-per-check organization is good. Anchor 4 ('good structure; most content appropriately placed; references mostly clear; minor organization gaps') fits — the gap being the unspecified spec-doc paths and the deep relative link, which keep navigation from being fully clean.

Specificity

Quotes like "Verifies engine=ReplacingMergeTree, order_by=['unique_key'], silver delete+insert, read-time dedup of every RMT read (FINAL/QUALIFY/LIMIT 1 BY/union_by_tag), unique_key formula, absence of promotion machinery, ephemeral usage..., and Airbyte append_dedup sync mode" plus "Reports deviations with file paths and line numbers" enumerate multiple concrete, comprehensive actions with no vague filler. It clearly exceeds anchor 4 ('several specific actions; minor gaps') because coverage of the audit's checks is essentially exhaustive, matching anchor 5.

Completeness

The 'what' is explicit and detailed (audits dbt models/connectors against named conventions and reports deviations with paths and line numbers), but there is no 'Use when...' clause or equivalent explicit trigger guidance anywhere in the description. Per the judging guidelines, a missing 'Use when...' clause caps completeness at 3, which matches the anchor 'clear what but when is missing or only weakly implied'.

Trigger Term Quality

Natural terms a user of this stack would say are present — "dbt models", "connector configurations", "silver", "Airbyte", "dedup", "audit" — giving good keyword coverage. Not anchor 5 because it lacks common variations/synonyms and when-to-say-it phrases (e.g. 'connector PR', 'before dbt build', 'convention drift'), and not anchor 3 since the domain keywords go beyond a bare minimum.

Distinctiveness Conflict Risk

The niche is unambiguous — dbt/ClickHouse pipeline-convention auditing keyed to ReplacingMergeTree, silver models, Airbyte append_dedup, and a specific rules file path — so it is clearly distinguishable from any generic linting or dbt skill and unlikely to trigger the wrong skill. It matches anchor 5 ('clear niche with distinct triggers; minimal conflict risk') rather than anchor 4, which admits overlap with closely related skills.
