What it does
Level 11 The Oracle Well is an agent skill from kylesnowschwartz/claude-code-hero. Claude Code Hero Level 11: The Oracle Well -- connect an MCP server and gain a new tool
Its SKILL.md is about 1.8k 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 Agent Workflows, covering MCP servers. It works with Model Context Protocol.
When your agent uses it
- Tasks that involve MCP servers
Example prompts
- “/level-11-the-oracle-well”
What it can do on your machine
Read from SKILL.md and the folder at commit 4abcc6d. 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:
rubyclaude
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):
docs.anthropic.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
Level 11 The Oracle Well loads about 1.8k tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 1,028 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 1,028 words (~1,808 tokens).
“Create .mcp.json and connect the Oracle -- an MCP server shipped with this plugin -- so Claude gains a tool it did not have before.”
