Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00020 | $0.00183 |
| Opus 5 | $0.00010 | $0.00092 |
| Sonnet 5 | $0.00004 | $0.00037 |
| Haiku 4.5 | $0.00002 | $0.00018 |
Grade A, and why
chorus-claude 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 6d 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
Chorus: Delegate to Claude
This skill delegates tasks to Claude Code when the user asks for a second opinion from Claude or wants to compare answers.
When to use
- User explicitly asks to delegate to Claude
- User wants a second opinion from Claude
- User wants to compare Claude's answer with Codex's
- User asks "what would Claude say?" or similar
Invocation
Run Claude Code non-interactively:
claude --print "<task>" --dangerously-skip-permissions
The --print flag runs Claude in non-interactive mode.
The --dangerously-skip-permissions flag is required for automated execution.
Output handling
Return Claude's output verbatim — no paraphrasing, no summaries.
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.

chorus-claude is a skill published in the GitHub repository valpere/chorus (10 stars, last pushed 3mo ago), licensed MIT. It adds 20 tokens to every session and 183 once invoked, about $0.0001 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 2026-08-31.
