What it does

Gf is an agent skill from codejunkie99/Gateflow-Plugin. Primary SystemVerilog/RTL orchestrator for GateFlow. Routes to specialist agents, runs verification, and iterates until working. Use when the user wants to create, test, fix, or implement any RTL design — FIFO, UART, AXI, state machines, or any digital hardware module.

Its SKILL.md is about 7.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. 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

The user wants to create
Implement any RTL design — FIFO
Any digital hardware module

Example prompts

“/gf”

Workflow steps

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

Confirm SystemVerilog Task
MANDATORY - Ask Clarifying Questions
Plan First (for creation tasks)
Build in Parallel (for creation tasks)

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 nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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

Gf loads about 7.1k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 1,967 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~68
When it runs · the whole SKILL.md, loaded when a task matches: ~7.1k

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 passed

The automated check found no risky patterns in SKILL.md.

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 1,967 words (~7,148 tokens).

When should I use Gf?

Gf fits situations like: the user wants to create; implement any RTL design — FIFO; any digital hardware module.

How do I install Gf in Claude Code?

Run `npx skills add codejunkie99/Gateflow-Plugin --skill gf -a claude-code`. Or copy the skill folder (plugins/gateflow/skills/gf in codejunkie99/Gateflow-Plugin) into .claude/skills/gf in your project. Claude Code loads it when a task matches its description.

Can I use Gf in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add codejunkie99/Gateflow-Plugin --skill gf -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/gf, .gemini/skills/gf, .github/skills/gf and .opencode/skills/gf in your project.

What does Gf need to run?

SKILL.md names no scripts, command-line tools or credentials: Gf is instructions for the agent only.

Does Gf access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Gf safe to install?

What licence does Gf use?

Gf has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Gf use?

About 7.1k tokens (SKILL.md is roughly 29k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
