Gf Plan

What it does

When your agent uses it

• Wants to plan a new design
• Architect a complex feature
• Understand how to implement hardware before coding

Example prompts

• “plan a DMA controller”
• “design a UART”
• “architect the memory subsystem”
• “/gf-plan”

Requirements

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

Workflow steps

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

1. 1Understanding Requirements
2. 2Analyze Existing Codebase
3. 3Architecture Design
4. 4Implementation Plan
5. 5Output

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
  • Bash
  • Task
  • WebFetch
  • AskUserQuestion
  • Skill

  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 and 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 Plan loads about 5.9k tokens when it runs, and up to ~18k if it reads all its reference files. Until then it costs about 82 tokens; SKILL.md has 1,003 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~82

When it runs · the whole SKILL.md, loaded when a task matches

~5.9k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~18k

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.

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 1,003 words (~5,897 tokens).
