What it does
Benchmark E2E is an agent skill from vercel/vercel-plugin, published by the product's own GitHub organization. End-to-end benchmark suite for vercel-plugin. Runs realistic projects through skill injection, launches dev servers, verifies everything works, analyzes conversation logs, and produces an improvement report for overnight self-improvement loops.
Its SKILL.md is about 1.3k 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 Testing & QA, covering End-to-end testing. It works with Vercel. 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 End-to-end testing
Example prompts
- “/benchmark-e2e”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- runner — Creates test dirs, installs plugin, runs claude --print with VERCEL_PLUGIN_LOG_LEVEL=trace
- verify — Detects package manager, launches dev server, polls for 200 with non-empty HTML
- analyze — Matches JSONL sessions to projects via run-manifest.json, extracts metrics
- report — Generates report.md and report.json with scorecards and recommendations
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:
bunclaude
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Benchmark E2E loads about 1.3k tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 359 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 359 words (~1,339 tokens).
“Single-command pipeline that creates projects, exercises skill injection via claude --print, launches dev servers, verifies they work, analyzes conversation logs, and generates actionable improvement reports.”
