.agents/skills/decocms-v6-to-v7-upgrade/SKILL.md

decocms-v6-to-v7-upgrade is a skill for Claude Code, Codex from decocms/blocks. It costs 146 tokens per session (4,980 once invoked), scanned A, original, no licence file.

A migration guide for TanStack Start sites using older Deco CMS packages. Deco CMS is a content-management system, and TanStack Start is a web application framework.

In plain words
What is it for?
It helps upgrade sites from `@decocms/start` 6.x or `@decocms/apps` 5.x to the corresponding 7.x packages.
Why use it?
It helps replace the old combined packages with the newer split package structure without guessing which dependencies and changes are required.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is decocms/blocks's own configuration. It tells Claude Code and Codex how to work on blocks itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything blocks configures →

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

decocms-v6-to-v7-upgrade scanned grade A with 1 finding 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 2d 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.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
