Testbench verification best practices and patterns. An agent skill from codejunkie99/Gateflow-Plugin.

  • Works in 12 steps: Testbench Structure → Transaction Class → Driver → …

What it does

Tb Best Practices is an agent skill from codejunkie99/Gateflow-Plugin. Testbench verification best practices and patterns. This skill should be used when the user needs testbench architecture guidance, verification methodology, or wants to write professional-quality testbenches. Example requests: "testbench best practices", "how to structure TB", "verification patterns"

Its SKILL.md is about 3.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: AI-powered SystemVerilog development assistant — design, verify, debug, and deliver working RTL with natural language.

When your agent uses it

  • Needs testbench architecture guidance
  • Verification methodology
  • Wants to write professional-quality testbenches

Example prompts

  • “testbench best practices”
  • “how to structure TB”
  • “verification patterns”
  • “/tb-best-practices”

Requirements

  • Pre-approved tools (allowed-tools): Grep, Glob, Read, Write, Edit, Bash, WebFetch, Task

Workflow steps

12 steps, taken from the step headings in SKILL.md.

  1. Testbench Structure
  2. Transaction Class
  3. Driver
  4. Monitor
  5. Scoreboard
  6. Randomization Best Practices
  7. Coverage Best Practices
  8. Threading Patterns
  9. Interface Best Practices
  10. Assertions in Testbench
  11. Test Organization
  12. Checklist

What it can do on your machine

Read from SKILL.md and the folder at commit bf7e94c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Grep
    • Glob
    • Read
    • Write
    • Edit
    • Bash
    • WebFetch
    • Task

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • make

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • picture.iczhiku.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tb Best Practices loads about 3.5k tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 444 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~80
When it runs · the whole SKILL.md, loaded when a task matches
~3.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Grep, Glob, Read, Write, Edit, Bash, WebFetch, Task

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 444 words (~3,506 tokens).

“Professional verification patterns for SystemVerilog testbenches.”
