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 | $0.00799 | $0.00799 |
| Opus 5 | $0.00400 | $0.00400 |
| Sonnet 5 | $0.00160 | $0.00160 |
| Haiku 4.5 | $0.00080 | $0.00080 |
Grade A, and why
pantheon-legacy 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.

Pantheon Agent System — Cline
This project uses the Pantheon multi-agent framework with 14 specialized agents.
Available Agents
| Agent | Role |
|---|---|
| @aphrodite | Frontend specialist — React 19, TypeScript strict, WCAG accessibility, responsive design, TDD, modern API patterns, deprecated npm detection. Calls apollo for discovery, sends to themis for review. |
| @apollo | Read-only investigation scout — 3–10 parallel searches across codebase, external docs, and GitHub. Called by: athena, zeus, hermes, aphrodite, demeter. No edits, no commands. |
| @athena | Strategic planner & architect — research-first, plan-only, never implements. Plans include quality gates (ruff/Biome, dep detection, LTS policy). Calls apollo for discovery. |
| @demeter | Database specialist — SQLAlchemy 2.0, Alembic, query optimization, N+1 prevention, TDD migrations, modern DB libs. Calls apollo for discovery, sends to themis. |
| @gaia | Remote sensing domain specialist — satellite image processing, spectral analysis, SAR, change detection, time series, ML/DL classification. Read-only analysis of geospatial data. |
| @hephaestus | AI tooling & pipelines specialist — LangChain/LangGraph chains, RAG architecture, vector stores, embedding strategies. Forges AI infrastructure. Calls apollo, sends to themis. |
| @hermes | Backend specialist — FastAPI, Python, async, TDD (RED→GREEN→REFACTOR), modern Python stdlib, obsolete lib detection. Calls apollo for discovery, sends to themis. |
| @iris | GitHub operations specialist — branches, pull requests, issues, releases, tags. Called by zeus after review. Never pushes or merges without explicit human approval. Integrates with VS Code GitHub Pull Requests extension. |
| @mnemosyne | Memory bank quality owner — initializes .pantheon/memory-bank/, writes ADRs and task records on explicit request. Called by zeus. Never invoked automatically after phases. |
| @nyx | Observability & monitoring specialist — OpenTelemetry tracing, token/cost tracking, agent performance analytics, LangSmith integration. Calls apollo for discovery, sends to themis. |
| @prometheus | Infrastructure + model provider specialist — Docker, CI/CD, multi-model routing, cost optimization, provider abstraction |
| @talos | Hotfix express lane — direct fixes for small bugs, CSS, typos, minor logic. No TDD ceremony, no orchestration overhead. Standalone, no subagents. Escalates complex issues to zeus. |
| @themis | Quality & security gate — ruff/Biome linting, dead/legacy code detection, OWASP Top 10, coverage >80%, correctness, deprecation audit. Called by implementers; escalates blockers to zeus. |
| @zeus | Central orchestrator — never implements. Delegates to: athena, apollo, hermes, aphrodite, demeter, prometheus, themis, iris, mnemosyne, talos, hephaestus, nyx |
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.

pantheon-legacy AGENTS.md is an instructions file published in the GitHub repository ils15/pantheon-legacy (10 stars, last pushed 4d ago), licensed MIT. It adds 799 tokens to every session, about $0.0040 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
