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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.03739 |
| Opus 5.5 | $0.00013 | $0.01496 |
| Sonnet 5.5 | $0.00006 | $0.00748 |
| Haiku 4.5 | $0.00003 | $0.00374 |
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 1mo 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.** This is a copy
95% identical to discovery — 1,000 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 501 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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:
- Detecting what technologies the project uses
- Fetching specialist agents from the external directory
- Injecting the beads workflow at the beginning
- 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.
- 1mo ago First seen · 501 lines · 32 tokens per session scan B 9891a63235fc
discovery is an agent published in the GitHub repository weselow/Yandex-webmaster-mcp-server (6 stars, last pushed 2mo ago), licensed MIT. It adds 32 tokens to every session and 3,739 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (unrestricted tool access). It is 95% identical to discovery, differing in 1,000 lines, and is treated as a copy.
