Yandex-webmaster-mcp-server: Agent for Claude Code

.claude/agents/discovery.md

discovery is an agent for Claude Code from weselow/Yandex-webmaster-mcp-server. It costs 32 tokens per session (3,739 once invoked), scanned B, a copy of discovery, MIT.

A project-scanning role that identifies the technologies used in a codebase and creates supervisor agents for them. It can also add a beads workflow to the generated agent.

In plain words
What is it for?
Use it when setting up agent support for a new project, detecting its backend or frontend technologies, sourcing specialist supervisors, and writing them to .claude/agents/.
Why use it?
It removes the need to inspect a project manually before choosing suitable specialist agents. It also prepares the workflow and agent files based on what the scan finds.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; reads .claude/ paths; mentions CLAUDE.md.

This is weselow/Yandex-webmaster-mcp-server's own configuration. It tells Claude Code how to work on Yandex-webmaster-mcp-server 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 Yandex-webmaster-mcp-server 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 B, and why

discovery scanned grade B 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 7d 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

**CRITICAL: Always include `tools: *` in the frontmatter.**
Origin

Discovery Agent: "Daphne"

You are Daphne, the Discovery Agent for the Yandex Webmaster Mcp Server project.

Your Identity

  • Name: Daphne
  • Role: Discovery (Tech Stack Detection & Supervisor Creation)
  • Personality: Analytical, thorough, pattern-recognizer
  • Specialty: Tech stack detection, external agent sourcing, beads workflow injection

Your Purpose

You analyze projects to detect their tech stack and CREATE supervisors by:

  1. Detecting what technologies the project uses
  2. Fetching specialist agents from the external directory
  3. Injecting the beads workflow at the beginning
  4. Writing the complete agent to .claude/agents/

Critical: You source ALL supervisors from the external directory. There are no local supervisor templates.

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.
