afo

afo is a command for Claude Code from jayvee/aigon. It costs 15 tokens per session (503 once invoked), scanned A, original, Apache-2.0.

A command that opens a feature's separate Git worktree and starts a chosen coding agent in it. A worktree is an isolated copy of the repository for working on one change.

In plain words
What is it for?
Use it to open the latest or a selected feature worktree and start Claude Code, Cursor, Antigravity, or Codex there.
Why use it?
It removes the setup work of finding the right worktree and launching the agent. Separate worktrees help keep feature changes apart from other work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

afo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

feature-open

Open a feature worktree in terminal and automatically start the AI agent with /aigon:feature-do.

Usage

/aigon:feature-open [feature-id] [agent-code]
  • /aigon:feature-open — open the most recently created worktree
  • /aigon:feature-open 77 — open any worktree for feature 77
  • /aigon:feature-open 77 cx — open specifically the cx (Codex) worktree for feature 77

Agent Mappings

Code Agent Command Mode
cc Claude Code claude --permission-mode acceptEdits Auto-edits, prompts for risky Bash
cu Cursor agent --force Auto-approves commands (yolo mode)
ag Antigravity agy --dangerously-skip-permissions Auto-approves all
cx Codex codex --full-auto Workspace-write, smart approval

Safe in worktrees since you can always git reset --hard.

Permission Tips

When an agent asks for permission, here's how to quickly allow:

Agent Allow once Allow always Toggle full-auto
Claude Code Press Enter at prompt Choose "Always allow" at prompt Shift+Tab cycles modes
Cursor Click "Run" Click "Add to allowlist" Enable YOLO in settings
Codex Approve at prompt "Allow and remember" (session) /mode command

Step 1: Run the CLI command

aigon feature-open {{args}}

This will:

  1. Find the matching worktree
  2. Create a Warp launch configuration
  3. Open Warp with the worktree directory
  4. Auto-run the agent CLI with /aigon:feature-do <ID>

Step 2: Confirm to user

Tell the user:

  • Which worktree was opened
  • Which agent was launched with which feature ID
  • That the agent should start implementing automatically

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
