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 | $0.00054 | $0.00701 |
| Opus 5.5 | $0.00022 | $0.00280 |
| Sonnet 5.5 | $0.00011 | $0.00140 |
| Haiku 4.5 | $0.00005 | $0.00070 |
Grade A, and why
account-reconciliation 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 2mo 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 — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Account Reconciliation
Compares the synthetic and custodial views of an account to surface any discrepancies.
Step 1 — Get the Synthetic Account
If you have the synthetic account UID:
get-synthetic-account uid=<synthetic_account_uid>
If you need to find it:
get-synthetic-accounts
Record from the synthetic account:
uidnet_usd_balance— the reported balance on the synthetic layernet_usd_pending_balancenet_usd_available_balancecustodial_account_uids— the underlying custodial accountsasset_balances— per-asset breakdown includingcurrent_usd_valueper custodial account
Step 2 — Get the Custodial Account(s)
For each UID in custodial_account_uids:
get-custodial-account uid=<custodial_account_uid>
Record the custodial account's reported balance for comparison.
If you need to find custodial accounts:
list-custodial-accounts
Step 3 — Pull Synthetic Line Items
list-synthetic-line-items
Filter for entries where synthetic_account_uid matches the account from Step 1.
For each line item record:
amount,currencydescriptionbalance_after— running balance after this entrytransaction_uid— back-reference to the originating transactioncreated_at
The final balance_after in chronological order should equal net_usd_balance
from Step 1.
Step 4 — Pull Custodial Line Items
list-custodial-line-items
Filter for entries where custodial_account_uid matches the account from Step 2.
For each line item record:
amount,currencydescriptionbalance_aftertransaction_uidcreated_at
Step 5 — Cross-Reference Transactions
For any transaction_uid that appears in synthetic line items but not custodial
line items (or vice versa), fetch the full transaction:
get-transaction uid=<transaction_uid>
Check the transaction status — pending transactions may not yet appear on
both sides.
Step 6 — Compare and Report
| Check | Expected |
|---|---|
Synthetic net_usd_balance |
Equals sum of synthetic line item amounts |
| Custodial balance | Equals sum of custodial line item amounts |
| Synthetic balance vs. custodial balance | Should match (within pending amounts) |
| Every synthetic line item has a matching custodial line item | Yes, via transaction_uid |
| No unmatched custodial line items | Confirm no orphaned custodial entries |
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.

account-reconciliation is a skill published in the GitHub repository newline53/newline-mcp-server (2 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 54 tokens to every session and 701 once invoked, about $0.0002 per session on Opus 5.5. 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.
