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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.00516 |
| Opus 5 | $0.00010 | $0.00258 |
| Sonnet 5 | $0.00004 | $0.00103 |
| Haiku 4.5 | $0.00002 | $0.00052 |
Grade A, and why
lingtai-update-homebrew 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 12d 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
Homebrew path and tap exploration
Nested lingtai-update reference. The supported formula is
lingtai-ai/lingtai/lingtai-tui. brew install still works for a first
install, but /update-tui, lingtai-tui self-update, and lingtai-tui doctor no longer run brew upgrade against it — a detected Homebrew install
now migrates (with explicit consent) to LingTai's native installer instead;
see the update-tui reference. The commands below remain useful for manual
exploration of an existing Homebrew install. The migration step itself never
touches the old formula/keg; removing it is a separate, interactive-only
consent step (the startup "Remove the old Homebrew installation now? [y/N]"
prompt, see update-tui) — self-update and doctor never run brew uninstall and only report the manual command:
brew install lingtai-ai/lingtai/lingtai-tui
brew update
brew upgrade lingtai-ai/lingtai/lingtai-tui
brew info lingtai-ai/lingtai/lingtai-tui
brew --repository
The release workflow writes Lingtai-AI/homebrew-lingtai/lingtai-tui.rb from
the tagged source tarball, builds tui and portal, and runs the TUI version
smoke test. To inspect the installed formula and its origin, pair brew info
above with brew cat lingtai-ai/lingtai/lingtai-tui; brew --repository
locates the checkout, so inspect the reported tap directory. Treat manual tap
edits as debugging only; release automation owns normal formula updates.
The formula builds Go and the embedded portal frontend and runs its own
connectivity probes. The mainland reference owns the HOMEBREW_* proxy and
registry overrides and their non-guaranteed mirror behavior.
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.

lingtai-update-homebrew is a skill published in the GitHub repository Lingtai-AI/lingtai (673 stars, last pushed yesterday), licensed Apache-2.0. It adds 20 tokens to every session and 516 once invoked, about $0.0001 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 2026-08-30.
