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 | $0.01900 | $0.01900 |
| Opus 5 | $0.00950 | $0.00950 |
| Sonnet 5 | $0.00380 | $0.00380 |
| Haiku 4.5 | $0.00190 | $0.00190 |
Grade A, and why
claude-collider 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 10d 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

Claude Collider
Claude Collider is an MCP server that lets Claude generate and execute SuperCollider code in real-time for live music synthesis.
Skills
| Skill | Description |
|---|---|
/claude-collider |
Live code music with SuperCollider |
/play-tape |
Play a tape file (loads patterns, effects, arrangement) |
/arrange-tape |
Compose a CCArrangement for a tape |
/record-tape |
Record a live session as a tape (md + scd pair) |
/songwriting |
Music theory reference for composing patterns and melodies |
Prefer MCP Tools Over Raw SC Code
Always use the dedicated MCP tools (cc_fx, cc_sample, cc_midi, cc_control, cc_recording, cc_output, cc_reboot, cc_status) instead of writing equivalent SuperCollider code with cc_execute. The tools handle error cases, validate input, and keep the server state consistent.
Use cc_execute only for things the tools don't cover: Pdef/Ndef definitions, custom SynthDefs, CCArrangement, and other raw SC code.
Quick Reference
- Drums need
\freq, 48— without it, drums sound wrong - Use Pdef for rhythms — patterns that repeat
- Use Ndef for continuous — pads, drones, textures
- Symbols not strings —
\kicknot"kick" - Semicolons between statements — no trailing semicolon
- NEVER Synth() inside Ndef — causes infinite spawning
CC API Reference
Main entry point stored in ~cc. Access subsystems via ~cc.synths, ~cc.fx, ~cc.midi, ~cc.samples, ~cc.recorder, ~cc.state.
CC - Main Class

stop |

clear |
Full reset: free all synths, patterns, effects, samples |
status |

reboot(device, numOutputs, onComplete) |
Restart the server |
~cc.synths - Synth Definitions
30 pre-built synths with cc_ prefix.

list |
Comma-separated list of synth names |
describe |
Detailed descriptions with params |
play(name, ...args) |

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.

claude-collider CLAUDE.md is an instructions file published in the GitHub repository jeremyruppel/claude-collider (53 stars, last pushed 1mo ago), licensed MIT. It adds 1,900 tokens to every session, about $0.0095 per session on Opus 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.
