Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.01423 |
| Opus 5 | $0.00021 | $0.00711 |
| Sonnet 5 | $0.00008 | $0.00285 |
| Haiku 4.5 | $0.00004 | $0.00142 |
Grade A, and why
agy 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
$agy — delegate to agy (Antigravity CLI)
Spawns the agy CLI in a detached tmux session so Codex can offload work to it. The user stays in the loop: they ask Codex when to check progress, what guidance to send, and when to stop.
Primitive
All operations go through a single dispatcher:
~/.agents/skills/agy/bin/agy-agent [--session <name>] <verb> [args]
Verbs:
start [task...]— create session (defaultcodex-agy), launchagy --dangerously-skip-permissions, type the task and press Enter. Returns immediately (non-blocking).send <message>— type message + Enter. For follow-up guidance. Does not interrupt current generation; agy queues the input.keys <name>— send a raw tmux key (Escape,C-c,Enter, etc.). Used for interrupts.capture [lines]— print last N ANSI-stripped rendered lines (default 500). Read-only, non-destructive.wait [stable] [timeout]— block until the agent goes idle, then exit. Run it in the foreground to block until the sub-agent finishes (the mode for Codex and other CLI orchestrators; see "Wait for completion" below).stable= secs the working indicator must stay gone before declaring idle (default 6);timeout= overall cap in secs (default 1800).stop—/quitthenkill-session. Destroys the tmux session.list— list activecodex-agy*sessions.
How to respond to the user
| User says | Do |
|---|---|
$agy <task> / "delegate to agy" |
start <task>, then run wait in the foreground (blocks this turn until agy is idle); on return, capture + report. |
$agy <task> + "tell me when it's done" / "notify me" |
Same as $agy <task>; foreground wait is already the default. |
| "check agy" / "progress" / "what's agy doing" / "ask agy for progress" | capture. Show the relevant tail, add a one-line diagnosis (running / idle / error / prompt). Do not send ESC. |
| "interrupt agy" / "esc agy" | keys Escape → capture. |
| "tell agy: X" / "send agy: X" | send X. |
| "kill agy" / "stop agy" | stop. |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

agy is a skill published in the GitHub repository phuongduyphan/cc-tmux-agents (8 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 1,423 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
