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 | $0.00697 | $0.00697 |
| Opus 5.5 | $0.00279 | $0.00279 |
| Sonnet 5.5 | $0.00139 | $0.00139 |
| Haiku 4.5 | $0.00070 | $0.00070 |
Grade A, and why
clopen 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 1mo 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.

AI Agent Guidelines for Clopen
This document provides guidelines for AI coding agents when working on the Clopen project.
WORK PROTOCOL
Before Coding
- Identify which stage is currently being worked on
- Understand the specific task that needs to be completed
- For PR-related tasks (e.g., "review PR #123", "check PR X"), read
MAINTAINERS.mdfirst to understand the PR workflow, review process, and maintainer conventions
During Coding
- Follow agreed-upon architecture and patterns
- Do not change technical decisions without discussion
- Ensure code matches the established folder structure
- Use chosen libraries and frameworks
- Do NOT run
bun run devorbun run buildcommands
After Coding
- Run
bun run checkandbun run lintto ensure code functions properly - Do not create any .md files unless explicitly instructed
- Suggest a branch name and commit message following CONTRIBUTING.md conventions:
- Branch:
<type>/<description>— lowercase, kebab-case, concise - Commit:
<type>(<scope>): <subject>— imperative mood, lowercase, no period, max 72 chars - Do NOT create the branch or commit automatically — only suggest the names for review
- Branch:
IMPORTANT RULES
- Be CONSISTENT with previously made decisions
- COMMUNICATE if existing plans need to be changed
- STOP after each stage for review
PROJECT-SPECIFIC GUIDELINES
Runtime & Package Manager
- Bun-only project — Node.js and Deno are NOT supported
- Always use
buncommands (never npm/pnpm/yarn) - Runtime checks exist in
bin/clopen.tsandbackend/index.ts
Architecture
- Backend: Bun + Elysia with WebSocket architecture
- Frontend: Svelte 5 with runes system ($state, $derived, $effect)
- Database: SQLite with migration system
Code Style
- TypeScript throughout the entire codebase
- Use
constby default; useletonly when reassignment is needed - In
.sveltefiles:letfor$stateand$bindable;constfor$derived,$props, functions - Use Svelte 5 runes for state management (not traditional stores)
- Follow Tailwind CSS v4 conventions
- Use custom logger module (
debug) instead of console.*
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.

clopen AGENTS.md is an instructions file published in the GitHub repository myrialabs/clopen (52 stars, last pushed yesterday), licensed MIT. It adds 697 tokens to every session, about $0.0028 per session on Opus 5.5. 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.
