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 | $0.00505 | $0.00505 |
| Opus 5 | $0.00253 | $0.00253 |
| Sonnet 5 | $0.00101 | $0.00101 |
| Haiku 4.5 | $0.00051 | $0.00051 |
Grade A, and why
claude-companions 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 11d 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.
What it actually says
Claude Companions — Installation Guide
This repo contains a library of communication tones for Claude Code. When a user asks to install, set up, or configure tones, follow this guide.
Installation
When the user asks to install (e.g., "install tones", "set up tones", "configure tones"), determine what they want:
1. Predefined Tones
- All tones:
make install-tones - Specific tones:
make install-tone TONE=<name>for each - None: Skip
2. Session-Start Trigger (random tone each session)
- Yes:
make install-hook - No: Skip
3. /tone Command (change/list/random tones mid-session)
- Yes:
make install-tone-skill - No: Skip
4. /create-tone Skill (generate new custom tones)
- Yes:
make install-create-skill - No: Skip
Quick Install
- Everything:
make install-all
Interpreting Natural Language
- "install without trigger" → install-tones + skills, skip hook
- "just give me gordon-ramsay and churchill" →
make install-tone TONE=gordon-ramsay && make install-tone TONE=churchill - "install everything" →
make install-all - "just the commands" → install skills only, skip tones and hook
Platform Detection
- macOS/Linux: Use
maketargets - Windows: Use PowerShell scripts:
.\scripts\windows\install.ps1 -Allor with switches:-Tones,-Hook,-ToneSkill,-CreateSkill,-Tone <name>
Uninstall
- Everything:
make uninstall - Just tones:
make uninstall-tones - Specific tone:
make uninstall-tone TONE=<name> - Windows:
.\scripts\windows\uninstall.ps1 -Allor with individual switches
Update
git pull && make install-all— pulls latest and re-copies all files
Status
make status— shows what's currently installed
Listing Tones
make list— shows all tones with their status (installed/available/local)
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.
