Flat fee. ``` Scanned 2026-10-21T19:27:14.061Z over sse. **22 tools: 1 do something that can't be undone, 10 change things and 11 only read.** | Group | Class | Tools | Claude Code | | --- | --- | --- | --- | | Deletes or cancels | destructive | 0 | deny | | Can't be undone | irreversible | 1 | ask | | Changes things | write | 10 | ask | | Only reads | read | 11 | allow | ## Findings No check matched anything in these tool definitions. ## Can't be undone (1) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `qtcl_send_transaction` - The name "qtcl_send_transaction" says "send": a word for sending, and what is sent cannot be taken back. Description, as the server wrote it: ```untrusted-server-text Submit a signed UTXO transaction to the QTCL network. Flat fee: 1 qsat. Finality: ~18 seconds. WORKFLOW: (1) pick nonce = int(time.time()*1000) [ms epoch]. (2) build payload = JSON.dumps({sender,recipient,amount,nonce}, sort_keys=True). (3) hash = SHA3-256(payload) as 64-char hex. (4) call qtcl_sign_message(message_hex=hash, private_key=key). (5) pass the 'signature_for_tx' field from step 4 as the 'signature' arg here, with the SAME nonce used in steps 1-4. CRITICAL: nonce must be a millisecond timestamp (>1700000000000) to avoid nonce_replay rejection. Never use sequential integers. ``` ## Changes things (10) Creates or changes something that can be changed back. Claude Code: ask. ### `qtcl_create_hybrid_wallet` - The name "qtcl_create_hybrid_wallet" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Create a new QTCL wallet with HYBRID post-quantum keys: Falcon-512 (NIST FIPS 206, 128-bit PQ security) + SL(3,p) (~70-bit classical). Returns full keypair dict with both Falcon and SL(3,p) components. Server does NOT retain secret keys. This is the v3 recommended wallet type — quantum-safe by default. ``` ### `qtcl_create_wallet` - The name "qtcl_create_wallet" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Create a new QTCL post-quantum wallet backed by a real HypΓ keypair (Schnorr-Γ over SL(3,p), 512-step random walk, SHA3-256² address). Returns private_key, public_key, address, and created_at. Store private_key securely — the server never retains it. ``` ### `qtcl_quantum_decrypt` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Decrypt quantum-bound or quantum-assisted ciphertext. Auto-detects mode from the ciphertext dict: quantum_bound → runs QLDPC pipeline on masked key, XOR-unmasks, decrypts attestation → tries classical first, falls back to quantum-assisted recovery classical → pure classical decrypt Returns: Plaintext (hex), plaintext_length, quantum_assisted flag, quantum_mode. ``` ### `qtcl_quantum_encrypt` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Quantum-bound encryption via IBM QLDPC hardware (ibm_marrakesh/ibm_kingston). Two modes: quantum_bound (async=false, default): XOR-masks the encapsulated key with a hardware-derived quantum key. Runs synchronously with 8192 shots for deterministic results. Recipient MUST use qtcl_quantum_decrypt to recover the key. attestation (async=true): Leaves encapsulated key unchanged, runs hardware in background. Attaches quantum_commitment as metadata. Classical decrypt still works. Returns: Ciphertext dict with quantum_commitment, quantum_status, quantum_mode, quantum_hardened, and all standard encryption fields. ``` ### `qtcl_quantum_pipeline` - The description's first verb is "run": a word for a change. Description, as the server wrote it: ```untrusted-server-text Run the full QLDPC pipeline directly on IBM quantum hardware. Encodes ciphertext bytes into a hyperbolic QLDPC code, runs on real IBM hardware (8192 shots), decodes syndromes via BP+OSD, and returns the recovered key fragment. Returns: Pipeline result with recovered_key_hex, residual, status, job_id, backend. ``` ### `qtcl_repair_utxos` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Nuclear UTXO repair: bypasses settlement machinery and directly inserts missing UTXOs from the transactions table. Use when qtcl_retro_settle reports success but UTXOs are still missing. Commits per-UTXO for maximum isolation. Returns repaired_blocks, repaired_utxos, recomputed_wallets counts. ``` ### `qtcl_retro_settle` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Retroactively settle all blocks whose UTXOs are missing from address_utxos. Safe to call repeatedly — idempotent. Returns counts of settled/skipped/error blocks. Use this when miner balance is lower than expected after mining blocks. ``` ### `qtcl_sign_message` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Sign a 32-byte message hash with a HypΓ private key using Schnorr-Γ. To sign a transaction, compute: SHA3-256(JSON.dumps({"sender": from_addr, "recipient": to_addr, "amount": amount_float, "nonce": nonce_int}, sort_keys=True)) → pass the 64-char hex as message_hex. The nonce MUST match the nonce you will use in qtcl_send_transaction. Returns the full signature dict (with canonical R/Z matrix fields) — pass the entire JSON output as the signature field to qtcl_send_transaction. CRITICAL: use the 'signature_for_tx' field from the response as the 'signature' argument to qtcl_send_transaction — do not extract sub-fields. ``` ### `qtcl_sign_message_hybrid` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text Sign a 32-byte message hash with HYBRID PQC (Falcon-512 + SL(3,p)). Both Falcon and SL(3,p) signatures are computed independently — verification requires BOTH to be valid. message_hex must be 64 hex chars (SHA3-256 of signing payload). private_key_json must be the full JSON output from qtcl_create_hybrid_wallet. Returns hybrid signature dict — pass verbatim as 'signature' to qtcl_send_transaction. ``` ### `qtcl_submit_block` - The name "qtcl_submit_block" says "submit": a word for a change. Description, as the server wrote it: ```untrusted-server-text Submit a fully PoW-solved and HypΓ-signed block to the chain. This is the unified miner submission path. The miner client performs PoW locally, signs the block header, then calls this with the complete payload. Required: height, block_hash, parent_hash, merkle_root, timestamp, nonce, miner_address, difficulty_bits, w_entropy_hash, hyp_signature, miner_public_key_hex. Optional: transactions (JSON array), w_state_fidelity, pq0, pq_curr, pq_last, mermin_value, mermin_violated, quantum_field_16x16x16. Returns: {status, height, block_hash, next_height, miner_reward_qtcl}. ``` ## Only reads (11) Looks things up and changes nothing. Claude Code: allow. ### `qtcl_get_balance` - The name "qtcl_get_balance" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Check QTCL balance for any address. Returns balance in base units (qsat), UTXO count, and UTXO list. 1 QTCL = 100 qsat. ``` ### `qtcl_get_block` - The name "qtcl_get_block" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Retrieve a block by height (integer) or hash (hex string). Omit both for the latest block. ``` ### `qtcl_get_chain_info` - The name "qtcl_get_chain_info" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Current blockchain state: height, latest block hash, mempool depth, oracle status, and system health vector. ``` ### `qtcl_get_oracle_registry` - The name "qtcl_get_oracle_registry" says "get": a word for reading.

Description, as the server wrote it: ```untrusted-server-text List active P2P peers in the QTCL Kademlia DHT network. ``` ### `qtcl_get_pqc_status` - The name "qtcl_get_pqc_status" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text Return PQC module status — shows whether Falcon-512 is available, key/signature sizes, security level, and hybrid signature overhead. Use to check if the server supports full hybrid PQ signatures. ``` ### `qtcl_get_price` - The name "qtcl_get_price" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text QTCL network quantum coherence metrics and valuation signals. Note: QTCL has no public USD exchange.
