What it does
Cdn Caching is an agent skill from vercel/vercel-plugin, published by the product's own GitHub organization. Debug Vercel CDN caching — cache hit rate, stale content, revalidation behavior, ISR + PPR, per-request cache reasons (cacheReason) and PPR state (pprstate), and costs.
Its SKILL.md is about 5.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.
It sits in Backend & APIs, covering Caching. It works with Vercel and Next.js. The repository describes itself as: Comprehensive Vercel ecosystem plugin — relational knowledge graph, skills for every major product, specialized agents, and Vercel conventions. Turns any AI agent into a Vercel…
When your agent uses it
- Tasks that involve Caching
Example prompts
- “/cdn-caching”
What it can do on your machine
Read from SKILL.md and the folder at commit 82fa491. 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:
vercelcurlnpx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
vercel.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
Cdn Caching loads about 5.3k tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 2,185 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,185 words (~5,254 tokens).
“You are an expert in understanding Vercel's caching infrastructure, and how the CDN Cache, ISR, and PPR work.”
