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 | $0.00558 | $0.00558 |
| Opus 5.5 | $0.00223 | $0.00223 |
| Sonnet 5.5 | $0.00112 | $0.00112 |
| Haiku 4.5 | $0.00056 | $0.00056 |
Grade A, and why
pantheon 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 2mo 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Instructions for AI agents working in this repository.
Agent Pantheon
This workspace uses a multi-agent system coordinated by Zeus (the master orchestrator):
Primary Agents
| Agent | Role | When Used |
|---|---|---|
| Zeus | Master Orchestrator | Default agent. Routes work to specialists |
| Prometheus | Strategic Planner | Complex planning, requirements gathering |
| Vulkanus | TDD Implementer | Code changes, bug fixes, validation |
| Mnemosyne | System Cartographer | Research, documentation |
| Oracle | Architecture Advisor | Hard debugging, design decisions |
| Argus | Adversarial Reviewer | Pre-landing quality gate |
Utility Agents
| Agent | Role |
|---|---|
| Explore | Contextual grep — "Where is X?" |
| Codebase Locator | Find files and directories |
| Codebase Analyzer | Understand how code works |
| Codebase Pattern Finder | Find similar implementations |
| Librarian | External library docs |
| Frontend Engineer | UI/UX implementation |
| Document Writer | Technical documentation |
| Translator | Translation and i18n |
| Thoughts Locator | Find research documents |
| Thoughts Analyzer | Analyze research insights |
Hunter Agents (dispatched by Argus)
| Agent | Role |
|---|---|
| Hunter Silent Failure | Finds swallowed errors |
| Hunter Type Design | Finds type invariant violations |
| Hunter Security | Finds security vulnerabilities |
| Hunter Code Review | Finds convention violations |
| Hunter Simplifier | Simplifies code with proof |
| Hunter Comments | Audits comment accuracy |
| Hunter Test Coverage | Fills test coverage gaps |

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.
