Conciseness

The body is lean with no explanations of concepts Claude already knows, but the decision logic is rendered three ways (ASCII "Decision Flow" diagram, "Routing Table", and "Decision Types" table), which is minor redundancy that could be trimmed.

Actionability

All guidance is copy-paste ready: "python scripts/db_route.py --json '{...}'", "--file database.db", "--list-routes", plus a full CLI reference and an executable Agent Workflow covering the common cases (route from identification JSON, identify+route in one step).

Workflow Clarity

The Agent Workflow gives a clear 3-step sequence (identify → route → execute) with explicit commands and per-decision actions, and "unknown_format → Manual investigation" provides an escape path; however there are no explicit validation checkpoints on the identification input (e.g., handling malformed JSON), keeping it below anchor 5.

Progressive Disclosure

Well-organized sections with a single correctly-referenced bundle file (scripts/db_route.py, which exists); no nested or buried references. Minor gap: the inline Routing Table duplicates what "--list-routes" prints, and path references are inconsistent ("scripts/db_route.py" vs "db-router/scripts/db_route.py").

Specificity

Concrete actions are explicit — "Route database files to appropriate extraction method", "Decides between DBeaver CLI (for supported formats) or db-extractor-* skills (for unsupported formats)" — with the decision criteria stated, so it sits above anchor 3 (1-2 actions, not comprehensive) though coverage of its full CLI surface (e.g., --list-routes, identify+route) is minorly incomplete.

Completeness

Both parts are present: the "what" is clear (routing database files to an extraction method between two options) and the "when" is explicit ("Use AFTER db-identify to determine extraction workflow"), which is equivalent trigger guidance so the completeness cap of 3 does not apply; the "when" is nonetheless narrow — it gives ordering but not the broader situations (e.g., when a user has an unidentified database file), fitting anchor 4.

Trigger Term Quality

Relevant keywords like "database files", "extraction", and "DBeaver CLI" are present, but common natural variations users would say are missing — no format names (sqlite, access, dbf, .db) or phrases like "export database"; the trigger is framed as workflow sequencing ("Use AFTER db-identify") rather than user language, matching anchor 3.

Distinctiveness Conflict Risk

It occupies a clear niche (routing between DBeaver CLI and db-extractor-* skills) with explicit positioning relative to db-identify, giving it distinct triggers and minimal conflict risk with neighboring skills.
