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 | $0.00453 | $0.00453 |
| Opus 5 | $0.00227 | $0.00227 |
| Sonnet 5 | $0.00091 | $0.00091 |
| Haiku 4.5 | $0.00045 | $0.00045 |
Grade A, and why
t1-t2-protocol AGENTS.md 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 6d 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.
What it actually says
Agent instructions (MCP hosts)
This repository ships an stdio MCP server with three tools: t1_protocol, t2_protocol, and checksum.
Recommended call order
t1_protocol— when the user question is ambiguous; decompose into L1–L4 tiers first.checksum— before T2 when the answer must follow structural format ([L1…]sections + trailing---).t2_protocol— evaluate confidence and adoption recommendations from a different model than the producer when possible.
Caller-side web verification (v2.6)
The server has no network access. If the topic involves time-sensitive facts (library status, prices, recent events), search on the caller side first, then call t2_protocol. See docs/caller-protocol.md.
Parameters
| Tool | Key args | Notes |
|---|---|---|
t1_protocol |
question, optional weight_hint, locale |
locale: en (default) or zh |
t2_protocol |
answer, optional weight_hint, locale |
Same weights as T1 |
checksum |
text |
Returns JSON (checksum_passed, errors); deterministic, stdlib-only |
Weight hints (English or Chinese): fact-first / 事实优先, efficiency-first / 效率优先, cost-first / 成本优先, robustness-first / 鲁棒性优先, general-first / 通用优先.
t1_protocolandt2_protocolreturn prompt templates for the host LLM. Onlychecksumreturns structured JSON.
Constraints for contributors and agents
- Keep
src/t1_t2_mcp_server.pystdlib-only (Layer 0). - Do not add web search, pip dependencies, or network I/O to the MCP server.
- Prefer extending caller-side rules/docs over bloating the server.
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.
