What it does
Gf Learn is an agent skill from codejunkie99/Gateflow-Plugin. SystemVerilog learning mode — generates exercises, reviews solutions, and teaches RTL design patterns. Use when the user wants to learn SystemVerilog, practice hardware design, get exercises, or understand verification methodology.
Its SKILL.md is about 1.3k 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 Development, covering Design patterns. 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 learn SystemVerilog
- Practice hardware design
- Understand verification methodology
Example prompts
- “/gf-learn”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Present 3-5 exercises of increasing difficulty
- Format each exercise as
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 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 Learn loads about 1.3k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 203 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 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 203 words (~1,257 tokens).
