At a glance
Synthesize SystemVerilog/Verilog with Yosys. An agent skill from codejunkie99/Gateflow-Plugin.
- Works in 6 steps: Check project context… → Pre-synthesis lint for unsupported SV… → Map board to Yosys synth target → …
- SKILL.md covers Tool Detection, Pre-Synthesis SV Subset Check, Workflow and Result Format
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Gf Synth is an agent skill from codejunkie99/Gateflow-Plugin. Synthesize SystemVerilog/Verilog with Yosys. Reports area, timing, and resource utilization. Warns about unsupported SV constructs. Example: "synthesize my design for iCE40"
Its SKILL.md is about 340 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.
Example prompts
- “synthesize my design for iCE40”
- “/gf-synth”
Requirements
- Pre-approved tools (allowed-tools): Bash, Read, Write, Glob, Grep, Task
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Check project context (.gateflow/project.yaml) for target
- Pre-synthesis lint for unsupported SV constructs
- Map board to Yosys synth target
- Run synthesis via sv-synth agent or directly
- Parse stat output for LUT/FF/BRAM/DSP
- Report structured result
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:
BashReadWriteGlobGrepTask
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).
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 Synth loads about 342 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 73 words of instructions outside code blocks.
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.
- NoteRuns commands with sudoSKILL.md:30
Linux: sudo apt install yosys - NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Bash, Read, Write, Glob, Grep, 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 73 words (~342 tokens).

Questions about Gf Synth
What does Gf Synth do?
Synthesize SystemVerilog/Verilog with Yosys. An agent skill from codejunkie99/Gateflow-Plugin. Gf Synth is an agent skill from codejunkie99/Gateflow-Plugin. Synthesize SystemVerilog/Verilog with Yosys.
How do I install Gf Synth in Claude Code?
Run `npx skills add codejunkie99/Gateflow-Plugin --skill gf-synth -a claude-code`. Or copy the skill folder (plugins/gateflow/skills/gf-synth in codejunkie99/Gateflow-Plugin) into .claude/skills/gf-synth in your project. Claude Code loads it when a task matches its description.
How do I install Gf Synth in Codex?
Run `npx skills add codejunkie99/Gateflow-Plugin --skill gf-synth -a codex`. Or copy the skill folder (plugins/gateflow/skills/gf-synth in codejunkie99/Gateflow-Plugin) into .agents/skills/gf-synth in your project. Codex loads it when a task matches its description.
Can I use Gf Synth 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-synth -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-synth, .gemini/skills/gf-synth, .github/skills/gf-synth and .opencode/skills/gf-synth in your project.
What does Gf Synth need to run?
SKILL.md names no scripts, command-line tools or credentials: Gf Synth is instructions for the agent only. Its frontmatter pre-approves these tools: Bash, Read, Write, Glob, Grep, Task.
Does Gf Synth 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 Synth safe to install?
Our automated static check of SKILL.md found notes only (runs commands with sudo; pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Gf Synth use?
Gf Synth 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 Synth use?
About 342 tokens (SKILL.md is roughly 1.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Gf Synth?
Skills that share tags, products or a category with Gf Synth: Time Tracking (sickn33/agentic-awesome-skills, 47k stars), Time Ledger (sickn33/agentic-awesome-skills, 47k stars), Agent Resource Allocator (ruvnet/ruflo, 74k stars) and Resources (windmill-labs/windmill, 18k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
