What is zuvo CLAUDE.md?

A skill for safely renaming code symbols or replacing function implementations across a codebase using Serena tools. A symbol is a named code element such as a function or class.

Use it to rename functions or other symbols, change function signatures, replace function bodies, inspect affected references, and run relevant tests afterward.

It reduces missed references and unsafe text-based edits when changing code structure.

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.

Model	Per session	Once invoked
Fable 5.1	$0.07197	$0.07197
Opus 5.5	$0.02879	$0.02879
Sonnet 5.5	$0.01439	$0.01439
Haiku 4.5	$0.00720	$0.00720

Security

Grade B, and why

zuvo CLAUDE.md scanned grade B with 2 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 10d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Zuvo Plugin — Project Guide

What this repo is

A Claude Code / Codex / Cursor / Antigravity / Kimi Code plugin. All skills are markdown files (SKILL.md). No TypeScript, no Python, no npm dependencies. package.json is metadata only (version field) — never run npm install.

Tech stack

Markdown. Shell scripts in scripts/. That's it.

How to update after making changes

For yourself (dev testing, no marketplace push)

./scripts/install.sh          # copies to Claude Code cache + Codex + Cursor + Antigravity + Kimi Code

Then restart Claude Code / Codex.

BUT — install.sh alone is NOT enough for Claude Code in all cases. Claude Code validates the plugin SHA from installed_plugins.json against the cache. If they don't match, skills may not load. To fully sync:

# Full local update (guaranteed to work):
./scripts/install.sh
claude plugin marketplace update zuvo-marketplace
claude plugin update zuvo@zuvo-marketplace
# Then restart Claude Code

One-command dev workflow (RECOMMENDED)

./scripts/dev-push.sh "description"

This does EVERYTHING in one command:

git add -A + commit with your message
git push origin main
Update marketplace SHA → push marketplace
Update installed_plugins.json SHA (fixes the stale SHA problem)
Copy files to Claude Code cache (all directories)
Build + install to Codex

After running: just restart Claude Code. No uninstall/install needed.

For end users (marketplace release)

./scripts/release.sh patch "description"

This does everything: version bump, commit, push, tag, marketplace SHA update. Users get it via claude plugin update zuvo.

Quick reference

What you want	Command
Push + sync everything (dev)	`./scripts/dev-push.sh "description"` then restart Claude/Codex
Test changes locally (dev)	`./scripts/install.sh` then restart Claude/Codex/Cursor/Kimi
Install every release on this machine by itself	`~/.zuvo/release-autoinstall --enable` (every 30 min: own clone, newest `vX.Y.Z` on main, install.sh, plugin update + enabled check, `~/.zuvo/key-sync`; `--status`, log `~/.zuvo/release-autoinstall.log`). Installs only tags SSH-signed by a key in `~/.zuvo/release-signers` — `docs/runbook/release-signing.md`
Release to users	`./scripts/release.sh patch "msg"`
Verify release works	`claude plugin uninstall zuvo@zuvo-marketplace && claude plugin install zuvo` then new session
User first install	`claude plugin marketplace add greglas75/zuvo-marketplace && claude plugin install zuvo`
User updates	`claude plugin marketplace update zuvo-marketplace && claude plugin update zuvo@zuvo-marketplace`

Changes

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.
