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 | $0.04273 | $0.04273 |
| Opus 5.5 | $0.01709 | $0.01709 |
| Sonnet 5.5 | $0.00855 | $0.00855 |
| Haiku 4.5 | $0.00427 | $0.00427 |
Grade A, and why
rudder 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 yesterday.
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
Guidance for human and AI contributors working in this repository.
1. Purpose
Rudder is open-source software for assigning, running, reviewing, and improving agent work. It connects goals, tasks, knowledge, runs, reviews, budgets, and workflows so agents can work within clear boundaries, collaborate, and move work forward.
Current behavior is defined by the implementation and tests. Use proposals in
doc/plans/ for design decisions that need discussion; no separate product
contract or registry update is required.
The product north-star metric is the weekly count of real agent-work loops successfully completed through Rudder end-to-end.
1.1 Repository Identity
- This repository began as a Rudder fork/derivative of an early version of Paperclip. When renaming or rebranding internals, prefer compatibility-preserving changes for legacy
paperclip*identifiers, config keys, and protocol values unless a deliberate breaking migration is planned. - Treat the product description above as the current canonical short introduction when updating README, product docs, and onboarding copy.
2. Read This First
Read docs in layers instead of scanning the whole doc/ tree.
Documentation folders have different audiences:
docs/is the public website documentation. It is user-facing, use-case-led, and written for installation, onboarding, and product understanding.doc/is internal product, engineering, plans, and archive documentation for contributors working on Rudder itself.
When the task is to improve website docs, edit docs/. When the task is to
change contributor/product-development guidance, edit doc/.
For product behavior or architecture work, start here:
doc/product/PRODUCT.md- Relevant implementation, tests, and existing proposals
For narrow docs, tooling, or skill edits, read the affected guidance and its callers directly. Expand only when product behavior or another boundary is affected.
Then choose the route that matches the work:
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.

rudder AGENTS.md is an instructions file published in the GitHub repository Undertone0809/rudder (294 stars, last pushed yesterday), licensed Apache-2.0. It adds 4,273 tokens to every session, about $0.0171 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.
