SKILLEMALL.ai

B sql-linker

Use this skill when you need to query, insert, update, or delete records in the configured MySQL/PostgreSQL/SQLite database and you know the target table name and approximate schema. Triggers include: (1) explicitly requesting a SELECT/INSERT/UPDATE/DELETE on a named table; (2) asking for a specific record by ID or a specific filter; (3) requesting audit log review for sql_audit_log; (4) explicitly asking to bootstrap or inspect the sql-linker configuration. Do NOT trigger on generic "database", "查数据库", "SQL", or "CRUD" without a specific target table or intent.

How to improve

  1. The SKILL.md body exceeds 5,000 tokens: move reference detail into references/ and load it on demand.
  2. Add evals/evals.json with 4–6 real requests and expected answers: the full check will then use your cases instead of a model draft.
  3. Add a spec.yaml with triggers and assertions (skilltest init): the behaviour contract for CI.

Lint

  • warning frontmatter-yaml SKILL.md: the frontmatter is not valid YAML (YAML parse error: Unexpected scalar at node end at line 3, column 505: …figuration. Do NOT trigger on generic "database", "查数据库", "SQL", or "CRUD" wit… ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ); fields were read line by line. The usual cause is a colon inside an unquoted value
  • warning body-long SKILL.md body ≈ 12443 tokens (recommended < 5000); move details to references/
  • note frontmatter-key unknown frontmatter key "requires"

Process maturity 61/100

  • 0Result and completion. Does not say what the result is
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 40Execution cost. Instruction body is 12443 tokens: crowds the task out of the window
  • 60Tools and files. Uses tools (bash, python) that frontmatter does not declare
  • 70When it triggers. States when to use, but not when not to
  • 100Steps. 141 steps
  • 100Failures and branches. 3 branches, has a failure section
  • 100Consistency. Name and required fields are in place
  • 100Running it twice. Mutating operations check current state
  • 100Progress reporting. Reports progress
  • medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
  • low 20 top-level sections: this looks like several domains in one skill

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
  • -232 emoji in the instructions: noise for the model
  • +1No license
  • +2Single-language instructions
  • +3Description length 568: enough signal without eating the budget
  • +4Structure: 101 headings
  • +3Step-by-step instructions: 141 items
  • +4Has examples (36 code blocks)

Quality base 70; lint remarks subtract, signals add up to 100. Result: 61.
