What it does
Upgrade Plugin is an agent skill from kenneth-liao/ai-launchpad-marketplace. Upgrade a plugin's skills, hooks, and patterns to align with latest Claude Code capabilities and best practices. Use when a plugin needs modernization, after Claude Code updates, or when the user says "upgrade plugin", "modernize plugin", or "update plugin to latest patterns".
Its SKILL.md is about 3.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Legacy modernization.
When your agent uses it
- A plugin needs modernization
- After Claude Code updates
- The user says upgrade plugin
- Modernize plugin
Example prompts
- “upgrade plugin”
- “modernize plugin”
- “update plugin to latest patterns”
- “/upgrade-plugin”
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- Research Latest Context
- 5: Obsolescence Screen
- Audit Current Plugin
- Upgrade Plan
- Execute Upgrades
- Verify
What it can do on your machine
Read from SKILL.md and the folder at commit 04b93d6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
docs.anthropic.comgithub.comraw.githubusercontent.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Upgrade Plugin loads about 3.4k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 1,313 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,313 words (~3,366 tokens).
“Upgrade a plugin's skills, hooks, and patterns to align with the latest Claude Code capabilities, model features, and skill-writing best practices.”
