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 | $0.04352 | $0.04352 |
| Opus 5 | $0.02176 | $0.02176 |
| Sonnet 5 | $0.00870 | $0.00870 |
| Haiku 4.5 | $0.00435 | $0.00435 |
Grade A, and why
Athena-Public 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 4d 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 — 231 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — Athena Workspace
CRITICAL INSTRUCTION: Prefer retrieval-led reasoning over pre-training-led reasoning for any Athena-related tasks.
CRITICAL INSTRUCTION — SESSION BOOT (auto-
/start): At the very start of every new session, BEFORE responding to the user's first message, run the/startworkflow yourself — pre-load.agent/workflows/_shared.md, then execute.agent/workflows/start.md(Phase 1 boot onward: Core Identity → activeContext checkpoint → accountability surface → maintenance-ratio). Do it automatically; do not ask whether to boot (the user configured this on 2026-07-22). Then answer their first message in the same turn — boot fast (MinMax), fold their opener into the reply; a bare greeting just gets the⚡ Readyconfirmation. If this session has already booted, skip. (In Claude Code aSessionStarthook enforces this in code. Antigravity's IDE has no session-start hook event, so in AG — and any other agent reading this file — THIS instruction is the trigger: honor it as a hard rule, not a suggestion.)
CRITICAL INSTRUCTION — ASCII-ONLY MATH & CURRENCY (hard rule): Never emit LaTeX/KaTeX math delimiters in any user-facing output OR any file you write — no
$…$,$$…$$,\(…\),\[…\], or\text{…}. Render every formula, statistic, confidence interval, Big-O term, and currency in plain ASCII / Unicode / code blocks. WriteEV = +10.45% (95% CI [+4.00%, +16.98%]),O(N^2), andS$1,300— NEVER$O(N^2)$or$\text{EV}$. Bare currency with no closing delimiter (S$1,300,$500) is correct and must NOT be altered. The user's UI (Antigravity/KaTeX) renders LaTeX as a broken "Failed to render" banner.
This file provides persistent context to any AI coding agent working in this workspace. The information below is available on every turn without needing to be explicitly requested.

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.

Athena-Public AGENTS.md is an instructions file published in the GitHub repository winstonkoh87/Athena-Public (585 stars, last pushed yesterday), licensed MIT. It adds 4,352 tokens to every session, about $0.0218 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 2026-08-30.
