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 | $0.02769 | $0.02769 |
| Opus 5.5 | $0.01108 | $0.01108 |
| Sonnet 5.5 | $0.00554 | $0.00554 |
| Haiku 4.5 | $0.00277 | $0.00277 |
Grade A, and why
toughtongue-skills 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.
toughtongue-skills — Agent Guide
Skills + plugin manifests for the Tough Tongue AI MCP server. This repo is public and is installed directly into end users' agents — every word ships.
Rules
- MCP tool names are a contract. Skills may only reference tools that the
hosted MCP server exposes (catalog in
skills/ttai-agent/references/mcp/tools.md). If the server catalog changes, that file and the skills change in the same PR. - Skills are MCP-first. Every workflow ends in an MCP tool call
(
create_scenario,update_scenario,list_resources(sessions), ...) — never in "write a file to disk" or references to internal Tough Tongue AI repos, paths, or CLIs. - No secrets. Shipped MCP configs (
.mcp.json/mcp.json) carry only the server URL; clients sign in through the browser OAuth flow. Skills and docs in this repo describe OAuth sign-in only; for CI or server setups, link https://app.toughtongueai.com/docs/mcp/mcp-server#authentication and add no credential setup steps. Never hardcode tokens, user IDs, or org IDs. - Token discipline in SKILL.md files. Skills are loaded into agent
context; keep SKILL.md under ~250 lines and push depth into
references/files that agents load on demand. - Public bar. No internal jargon, no unfinished sections, no hallucinated features. Terminology: "Tough Tongue AI" (two words, matching the public brand at toughtongueai.com), not "ToughTongue AI". Positioning: the platform for tough conversations, with a dual storyline — some the AI takes (voice agents that call, demo, screen, book), others you nail (realistic roleplay for negotiations, interviews, coaching). Do not describe the platform as only roleplay/training, and do not drop the practice half either — lead with the automate + practice pairing.
Structure
Every skill name starts with ttai-. One main skill plus specialists; each
skill is self-contained and follows the Agent Skills standard
(https://agentskills.io/specification).
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.
