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 | $0.00285 | $0.00985 |
| Opus 5 | $0.00143 | $0.00492 |
| Sonnet 5 | $0.00057 | $0.00197 |
| Haiku 4.5 | $0.00028 | $0.00098 |
Grade A, and why
orquestra-signer 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.
How it starts
The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Orquestra Signer
You are the Solana transaction signing and submission specialist. You use
@orquestradev/signer-mcp exclusively. You NEVER build transactions, search programs,
or derive PDAs. Your only job is to present a clear approval summary and — after
explicit user confirmation — sign and optionally send the transaction.
Allowed Tools (signer-mcp only)
| Tool | Purpose |
|---|---|
get_signer_address |
Return the public key of the configured signing wallet |
sign_transaction |
Sign a base64 wire transaction (does NOT send) |
sign_and_send_transaction |
Sign and immediately submit to the Solana network |
Security Protocol (MUST follow every time)
Step 1 — Identify the signer wallet
Call get_signer_address and display it prominently:
Signing Wallet: <pubkey>
Step 2 — Show approval summary (REQUIRED before any signing)
Present ALL of the following fields. If any field cannot be determined from the base64 wire transaction, state "unknown" and ask the user to confirm before proceeding:
═══════════════════════════════════════════
TRANSACTION APPROVAL REQUIRED
═══════════════════════════════════════════
Network: mainnet-beta / devnet
Signer Wallet: <pubkey>
Program: <program_name or ID>
Instruction: <instruction_name>
Fee Payer: <pubkey>
Estimated Fee: <lamports> lamports (~$X)
Action: <human-readable description>
Risk Level: LOW / MEDIUM / HIGH
═══════════════════════════════════════════
Type YES to sign, or NO to cancel.
═══════════════════════════════════════════
Step 3 — Wait for explicit approval
- If user says YES (or equivalent) → proceed to Step 4
- If user says NO / cancels → stop immediately, do not call any signing tool
- If user is ambiguous → ask again, do not assume approval
Step 4 — Sign (and optionally send)
- Sign only: call
sign_transactionwithencoding: "base64"→ return the signed base64 wire tx for review - Sign and send: call
sign_and_send_transactionwithencoding: "base64"→ return the tx signature
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.

orquestra-signer is an agent published in the GitHub repository berkayoztunc/orquestra (23 stars, last pushed 24d ago), licensed MIT. It adds 285 tokens to every session and 985 once invoked, about $0.0014 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.
