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 | $0.18323 | $0.18323 |
| Opus 5.5 | $0.07329 | $0.07329 |
| Sonnet 5.5 | $0.03665 | $0.03665 |
| Haiku 4.5 | $0.01832 | $0.01832 |
Grade A, and why
ekbatan AGENTS.md scanned grade A with 1 finding 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 19d 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.

Project Overview
Ekbatan is a Java persistence and action framework built as an alternative to Spring Data. It is a library, not a standalone application. Its central idea is that in most business applications, you don't just want to save data — you want to save what happened alongside the data itself, atomically, so that the database always tells a complete and consistent story.
The framework is structured around the concept of an Action — a unit of business work. An Action doesn't write anything to the database directly. Instead, it declares its intent: what should be created, what should be updated. These declarations accumulate in an ActionPlan — a staging area that holds all planned changes without touching the database. Only after the action's logic completes successfully does the ActionExecutor step in, open a single database transaction, and flush everything at once: the domain objects to their tables, and the event records to the eventlog schema. If any part fails, nothing is written. This all-or-nothing guarantee means the eventlog.events table naturally becomes a reliable outbox — a stream of committed business facts that can be tailed by a CDC connector or polled and forwarded to Kafka, Pulsar, or any message broker, enabling event-driven architectures without dual-write problems.
The framework draws a deliberate line between two kinds of persistent objects. A Model is a domain aggregate whose changes matter — every mutation produces a ModelEvent that gets persisted in the eventlog alongside the action that caused it. You extend Model when downstream systems need to know what happened: a wallet was created, money was deposited, an order was shipped. An Entity is simpler — it gets persisted and version-tracked, but its changes are not recorded as events. You extend Entity for supporting data where the history of individual mutations is irrelevant: lookup tables, configuration records, auxiliary references that participate in an action but don't need their own event trail.
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.

ekbatan AGENTS.md is an instructions file published in the GitHub repository ekbatan-io/ekbatan (22 stars, last pushed today), licensed Apache-2.0. It adds 18,323 tokens to every session, about $0.0733 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
