Use it to check the installed and available Tree Ring versions, find the active executable, or update it after giving permission.
Why use it?
It helps identify outdated or shadowed installations and avoids changing the installation scope during an update.

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

tree-ring-update 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

Tree Ring Update

Resolve the real project root and read project-local .tree-ring/SKILL.md and .tree-ring/CLI.md when present. Prefer .tree-ring/bin/tree-ring for that project when it exists; otherwise resolve the active global binary with command -v tree-ring. Use which -a tree-ring to detect older shadowing copies.

For a read-only release check, run the selected binary:

tree-ring update --check

If the user asked only to check, report the installed version, available version, executable path, and install method without changing files. If the user already authorized an update, run tree-ring update; otherwise obtain permission immediately before the update. The updater must preserve the active project-local, direct-prefix, or Homebrew scope and verify official release assets. Never install a second copy merely to bypass an older active binary.

CLIs older than 0.15.0 lack the update command. Upgrade with the same manager or prefix: brew upgrade tree-ring for Homebrew, the official installer with --project --release latest for an existing project-local binary, or --install-dir <existing-prefix> --release latest for another direct install. Do not change global scope or edit shell startup files without separate user authorization.

After updating, verify the selected binary with --version, return to the actual project root, and run:

tree-ring --root .tree-ring init
tree-ring --root .tree-ring integrations status --verbose

Use .tree-ring/bin/tree-ring for both commands when the project has a local binary. Confirm the files remain under the intended project's .tree-ring/. Initialization refreshes managed guidance but does not prove harness activation.

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.
