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 | $0.01169 | $0.01169 |
| Opus 5.5 | $0.00468 | $0.00468 |
| Sonnet 5.5 | $0.00234 | $0.00234 |
| Haiku 4.5 | $0.00117 | $0.00117 |
Grade C, and why
OpenHBM AGENTS.md scanned grade C with 2 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

AGENTS.md
This file is the entry point for any AI coding agent (Claude, GPT, Gemini, or
otherwise) operating in this repository. It is the symlink-equivalent companion
to CLAUDE.md -- agents that look for AGENTS.md first should read both.
Read CLAUDE.md next. It contains the binding contract: SystemVerilog
subset, banned constructs, clock-domain rules, primitive library, CSR
generation rule, and the assertion-first workflow.
Operating principles
- Spec first, code second. Before writing any RTL, produce a port and parameter table, a cycle-by-cycle timing narrative, and SVA assertions for every protocol invariant. Then implement.
- Test-with against a Python golden reference. Every leaf IP gets a
dv/env/<ip>_ref.pymodel. Cocotb tests check RTL output against the reference, not against handwritten expected values. - Lint clean, formal clean, mutation-tested. A PR is not mergeable until
verible-verilog-lint,verilator -Wall --timing, the cocotb suite,sby(where applicable), andmcymutation coverage all pass the gate threshold (80/100 score; seetools/agent_eval/harness/scoring.py). - Hjson + reggen for every CSR. Never hand-write a CSR file.
- DCO on every commit.
git commit -s. No exceptions. - No JEDEC PDF redistribution. Spec summaries go in
docs/spec/, derived clean-room from the free-registration PDF held in a non-redistributable local cache. - No iEDA / OSCC code vendored into
hw/vendor/until export-controls counsel and license counsel both clear it. Seedocs/legal/export_control.md. Use iEDA via the prebuilt Docker image as a tool only.

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.

OpenHBM AGENTS.md is an instructions file published in the GitHub repository Netie-AI/OpenHBM (26 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 1,169 tokens to every session, about $0.0047 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
