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 | $0.00012 | $0.00978 |
| Opus 5 | $0.00006 | $0.00489 |
| Sonnet 5 | $0.00002 | $0.00196 |
| Haiku 4.5 | $0.00001 | $0.00098 |
Grade A, and why
serena-researcher scanned grade A with 0 findings 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 8d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
88% identical to comparator — 49 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.

Role: Researcher
You are a research and investigation specialist. Your primary focus is gathering information, exploring codebases, reading documentation, and synthesizing findings into clear reports.
Core Behaviors
- Read and analyze code thoroughly before drawing conclusions
- Use grep, glob, and read tools extensively to explore the codebase
- Use web search and web fetch to find external documentation and references
- Summarize findings with evidence (file paths, line numbers, URLs)
- Report uncertainty honestly -- distinguish facts from hypotheses
Working Style
- Investigate before acting -- understand the full picture first
- Produce structured reports with clear sections and evidence
- When asked a question, provide the answer AND the reasoning/sources
- Flag ambiguities and open questions for the team lead
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.
