BC Database Credential Security (Zero‑Exposure Edition)

Secure database credential management using MGC Blackbox 1.4.10. Supports MySQL, PostgreSQL, SQLite, MariaDB and other databases. Credentials are stored encrypted; local scripts retrieve them via HTTP API at runtime, while AI agents never touch plaintext.

How to improve

  1. The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
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 body-long SKILL.md body ≈ 5319 tokens (recommended < 5000); move details to references/
  • note frontmatter-key unknown frontmatter key "spec"
  • note frontmatter-key unknown frontmatter key "id"
  • note frontmatter-key unknown frontmatter key "platform_compatibility"
  • note frontmatter-key unknown frontmatter key "changelog"

Process rating: all ten parameters 53/100

  • 0Result and completion. Does not say what the result is
  • 30Running it twice. 3 mutating operations with no state check
  • 40Consistency. Frontmatter name (Database Credential Security (Zero‑Exposure Edition)) differs from the folder (mgc-database-security)
  • 50When it triggers. No condition that starts the skill
  • 50Failures and branches. 0 branches, has a failure section
  • 60Tools and files. Uses tools (bash, python, node) that frontmatter does not declare
  • 70Inputs and preconditions. Inputs and preconditions are listed
  • 70Execution cost. Instruction body is 5319 tokens
  • 85Steps. 59 steps, 3 vague phrases
  • 100Progress reporting. Reports progress
  • medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
  • low 25 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
  • -2localhost URLs: will not work for another user
  • -214 emoji in the instructions: noise for the model
  • +2Single-language instructions
  • +3Description length 255: enough signal without eating the budget
  • +4Structure: 56 headings
  • +3Step-by-step instructions: 59 items
  • +4Has examples (23 code blocks)
  • +1License stated

Quality base 70; lint remarks subtract, signals add up to 100. Result: 63.

ClawHub: suspicious
This documentation-only skill is mostly coherent, but it gives agents a pattern for running arbitrary SQL against production databases without clear confirmation or safety boundaries.
