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 | $0.16764 | $0.16764 |
| Opus 5.5 | $0.06706 | $0.06706 |
| Sonnet 5.5 | $0.03353 | $0.03353 |
| Haiku 4.5 | $0.01676 | $0.01676 |
Grade B, and why
Rivet AGENTS.md scanned grade B 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 27d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- `brew install --cask docker-desktop` needs sudo to link `docker-credential-osxkeychain` into How it starts

AGENTS.md
This file provides guidance to coding agents when working with code in this repository.
What Rivet is
An autonomous software engineering platform: you point it at a repository, describe a task, and it runs the whole workflow (read, plan, edit, test, review, open a PR). The interesting part is the job-execution system around the coding agent, not the code generation.
PRD.md and plan.md are at the repo root and are gitignored but present on disk. Read them
for product intent and milestone scope. docs/architecture.md describes the system as it actually
exists today and is the best starting point for any structural question.
Current state: Milestone 12 is complete. Rivet now has a static public website (apps/site, see
"The public site" below), structured diff and validation surfaces, append-only timeline motion,
deterministic capture and replay, two graded demo repositories, and a public recording of a real
issue-to-PR run. A replayed run remains an ordinary job written through the production writers.
M12 adds no table, column, job status, event type or failure category. Of its acceptance runs
A-H, A-D and F run in pnpm test, E is integration, G is the Docker-backed demo-repository suite,
and H is the recording published on 2026-08-22.
Milestone 11 is complete. Rivet can now be watched, and it defends itself. Traces, metrics and
correlated logs flow through a Telemetry port to an OTLP collector; every durable write passes a
Redactor; every API route is guarded by a session whose coverage is a test rather than a
convention; the unauthenticated edges and the spend are rate limited and the limiter fails closed;
every prompt boundary fences untrusted text; and a startup probe refuses to boot a worker whose
control plane a sandbox container can reach. M11's entire schema footprint is one nullable text
column, jobs.trace_context - no new table, no job status, no job event type and no failure
category. Its acceptance runs are A-H; A-F need no Docker and run in pnpm test, G is
apps/worker/tests/sandbox/network-isolation.sbx.test.ts, and H is
benchmarks/prompt-injection-bait/ plus pnpm demo:observability.
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.

Rivet AGENTS.md is an instructions file published in the GitHub repository xuanhieu2611/Rivet (2 stars, last pushed 4d ago), licensed MIT. It adds 16,764 tokens to every session, about $0.0671 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
