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 | $0.00313 | $0.00313 |
| Opus 5.5 | $0.00125 | $0.00125 |
| Sonnet 5.5 | $0.00063 | $0.00063 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
codex-pet-limit-rings AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Codex Pet Limit Rings Agent Notes
Goal
This repository packages codex-pet-limit-rings: a native macOS companion app that draws usage-limit rings around the current Codex pet without patching Codex.
Primary Contract
- Keep the Codex app bundle unmodified.
- Treat
tools/codex-pet-limit-rings.swiftas the app source. - Treat
tools/install-limit-rings.shandtools/uninstall-limit-rings.shas the public install/uninstall path. - Treat
skills/codex-pet-limit-rings/SKILL.mdas the reusable Codex-agent workflow. - Keep weather-pet code under
experiments/weather-pets/; it is not the main package.
Done When
For app changes, verify:
bash -n tools/*.sh
swiftc tools/codex-pet-limit-rings.swift -o tmp/codex-pet-limit-rings -framework AppKit -lsqlite3
tmp/codex-pet-limit-rings --preview tmp/limit-rings-preview.png --size 164
For packaged installs, also run tools/install-limit-rings.sh and verify:
pgrep -fl CodexPetLimitRings
launchctl print "gui/$(id -u)/com.codex-pet.limit-rings" >/dev/null
Do not commit tmp/, local logs, screenshots, user Codex state, or generated private pet assets.
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.
