Auto-detect IP blocks within FPGA and hardware codebases. An agent skill from codejunkie99/Gateflow-Plugin.
- Works in 9 steps: Missing Module Implementations → Stub Modules (Empty or TODO) → Standard IP Pattern Matching → …
- SKILL.md covers What This Detects, Detection Workflow, Auto-Fill Dispatch and Pattern Detection Rules, plus 7 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Gf Ip Detect is an agent skill from codejunkie99/Gateflow-Plugin. Auto-detect IP blocks within FPGA and hardware codebases. Scans for module instantiations, identifies missing implementations, matches standard IP patterns, and dispatches agents to fill gaps. Example: "scan for missing IP blocks", "detect what needs implementing", "find unimplemented modules", "auto-fill IP blocks"
Its SKILL.md is about 2.5k 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.
Example prompts
- “scan for missing IP blocks”
- “detect what needs implementing”
- “find unimplemented modules”
- “/gf-ip-detect”
Requirements
- Pre-approved tools (allowed-tools): Bash, Read, Write, Glob, Grep, Task, AskUserQuestion
Workflow steps
9 steps, taken from the step headings in SKILL.md.
- Missing Module Implementations
- Stub Modules (Empty or TODO)
- Standard IP Pattern Matching
- Interface Gaps
- Vendor IP Placeholders
- Scan Codebase
- Identify Gaps
- Report
- Auto-Fill (with user approval)
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:
BashReadWriteGlobGrepTaskAskUserQuestion
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 Ip Detect loads about 2.5k tokens when it runs. Until then it costs about 83 tokens; SKILL.md has 591 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.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Bash, Read, Write, Glob, Grep, Task, AskUserQuestion
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 591 words (~2,482 tokens).
“Scans hardware codebases to find IP blocks, identify gaps, and dispatch agents to implement missing pieces.”

Questions about Gf Ip Detect
What does Gf Ip Detect do?
Auto-detect IP blocks within FPGA and hardware codebases. An agent skill from codejunkie99/Gateflow-Plugin. Gf Ip Detect is an agent skill from codejunkie99/Gateflow-Plugin. Auto-detect IP blocks within FPGA and hardware codebases.
How do I install Gf Ip Detect in Claude Code?
Run `npx skills add codejunkie99/Gateflow-Plugin --skill gf-ip-detect -a claude-code`. Or copy the skill folder (plugins/gateflow/skills/gf-ip-detect in codejunkie99/Gateflow-Plugin) into .claude/skills/gf-ip-detect in your project. Claude Code loads it when a task matches its description.
How do I install Gf Ip Detect in Codex?
Run `npx skills add codejunkie99/Gateflow-Plugin --skill gf-ip-detect -a codex`. Or copy the skill folder (plugins/gateflow/skills/gf-ip-detect in codejunkie99/Gateflow-Plugin) into .agents/skills/gf-ip-detect in your project. Codex loads it when a task matches its description.
Can I use Gf Ip Detect in Cursor, Gemini CLI or GitHub Copilot?
