BF DB Index Advisor

Database index advisor that statically analyzes ORM query patterns to predict missing indexes before they become production bottlenecks. Scans SQLAlchemy, Django ORM, TypeORM, Prisma, GORM, ActiveRecord, and Sequelize code for columns used in WHERE/filter, ORDER BY, and JOIN conditions. Cross-references existing model index definitions and migration files to suppress already-indexed columns. Ranks recommendations by query frequency and outputs ready-to-run CREATE INDEX SQL + per-ORM migration snippets. Zero competitors on ClawHub — not a single db-index-advisor SKILL.md in 13,700+ files.

How to improve

  1. Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
  2. The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
  3. The text references files that are not there: add them or drop the references.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Against the Agent Skills spec

  • warning name-format name should be kebab-case (lowercase letters, digits, hyphens)
  • warning description-no-when description does not say WHEN to use the skill (no "use when")
  • warning body-long SKILL.md body ≈ 5094 tokens (recommended < 5000); move details to references/
  • warning missing-ref reference to a missing file: \w+
  • warning missing-ref reference to a missing file: ?:\w+\.
  • note frontmatter-key unknown frontmatter key "homepage"

Process rating: all ten parameters 26/100

Will not run. References files that are not bundled: \w+, ?:\w+\.
  • 0Tools and files. 2 referenced file(s) missing: \w+, ?:\w+\.
  • 0Result and completion. Does not say what the result is
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 0Failures and branches. Linear process with no failure handling
  • 0Progress reporting. Says nothing while it works
  • 20When it triggers. No condition that starts the skill
  • 30Running it twice. 7 mutating operations with no state check
  • 40Consistency. Frontmatter name (DB Index Advisor) differs from the folder (phy-db-index-advisor)
  • 70Execution cost. Instruction body is 5094 tokens
  • 100Steps. 10 steps

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

Quality signals

  • +5Description has no quoted example phrases that should trigger the skill
  • +4Description does not say when NOT to use the skill (false activations)
  • +3Output format is not stated: the model decides each time
  • +2Single-language instructions
  • +3Description length 594: enough signal without eating the budget
  • +4Structure: 13 headings
  • +3Step-by-step instructions: 10 items
  • +4Has examples (3 code blocks)
  • +1License stated

Quality base 70; lint remarks subtract, signals add up to 100. Result: 48.
