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 | $0.02965 | $0.02965 |
| Opus 5.5 | $0.01186 | $0.01186 |
| Sonnet 5.5 | $0.00593 | $0.00593 |
| Haiku 4.5 | $0.00297 | $0.00297 |
Grade A, and why
aesthetic-computer CLAUDE.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 20d 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.
How it starts
The opening of the file, as written. The whole thing — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. It is kept deliberately short (target: under 200 lines); domain detail lives in on-demand files noted throughout — read those when working in their area.
Execution Environment
Read ENVIRONMENT.md and resolve the active environment before applying
editor-specific instructions from any score. Claude Terminal on macOS uses its
local shell directly; Emacs MCP/fishy instructions apply only when the active
environment is emacs.
Project Overview
Aesthetic Computer (AC) is a mobile-first runtime and social network for creative computing. It's designed as a musical instrument-like interface where users discover memorizable paths through commands and published "pieces" (interactive programs). The system supports both JavaScript (.mjs) and KidLisp (.lisp) pieces.
Agent Memory (Local-First)
When @jeffrey is working, Claude hook events are written to a local encrypted memory store first.
- Hook:
.claude/settings.json→UserPromptSubmit→node memory/hook.mjs - Git hook:
.githooks/post-commit→ commit log + Codex import + remote flush - Local store:
~/.ac-agent-memory(overridable viaAGENT_MEMORY_HOME); AES-256-GCM; redacted before indexing/sync - CLI:
node memory/cli.mjs(list,remember,checkpoint,doctor,profile,flush-remote); Codex import vianode memory/codex-sync.mjs - Remote writes are optional and disabled by default (
AGENT_MEMORY_REMOTE_ENABLED=true+AGENT_MEMORY_REMOTE_URL=...to enable).remembercontinuity is lineage (remembered_from), not session takeover.
AestheticAnts & Score.md
Automated maintenance system ("AA"). Main score: SCORE.md; ant mindset/rules: ants/mindset-and-rules.md. Read both before contributing.
Important: Do not modify ants/mindset-and-rules.md unless you are the queen (@jeffrey).
The Hand (Code Style)
HAND.md at the repo root is the code-style guide — companion to papers/VOICE.md (prose). Read it before writing or carving core code. Key idea: leaves (pieces) stay small and can be loop-generated; the foundational libs are the instrument and want knowability over raw terseness. The active "rehandify" campaign and its guardrails live at the bottom of that file.
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.

aesthetic-computer CLAUDE.md is an instructions file published in the GitHub repository whistlegraph/aesthetic-computer (91 stars, last pushed yesterday), licensed ISC. It adds 2,965 tokens to every session, about $0.0119 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.
