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 | $0.00009 | $0.00489 |
| Opus 5 | $0.00005 | $0.00244 |
| Sonnet 5 | $0.00002 | $0.00098 |
| Haiku 4.5 | $0.00001 | $0.00049 |
Grade A, and why
reconciliation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Reconciliation
Perform account reconciliation for "$ARGUMENTS". Compare internal records against external statements or related accounts to identify and resolve differences.
Prerequisites
None — utility skill, run anytime. Most commonly used after Phase 3 (ledger) when account balances are available.
Process
-
Identify accounts to reconcile:
- What internal account is being reconciled? (e.g., cash, accounts receivable, accounts payable, intercompany)
- What is the external source or related account? (bank statement, customer statement, sub-ledger, vendor statement)
- What period is being reconciled?
-
Gather balances:
- Record the internal book balance (per general ledger)
- Record the external or comparison balance (per bank/vendor/customer statement)
- Note the difference to be explained
-
Identify reconciling items:
- Timing differences — items recorded in one set of books but not yet in the other
- Outstanding checks (issued but not yet cleared)
- Deposits in transit (recorded but not yet credited)
- Unrecorded transactions (bank fees, interest, direct deposits)
- Errors — mistakes in either set of records
- Adjustments needed — entries required to correct the book balance
- Timing differences — items recorded in one set of books but not yet in the other
-
Prepare reconciliation:
- Start with one balance, add/subtract reconciling items to arrive at the other
- Every dollar of difference must be explained
- Flag any aged or unresolved reconciling items
-
Write the artifact to
.metapowers/accounting/$ARGUMENTS/reconciliation.mdwith sections:- Reconciliation Summary — account name, period, book balance, external balance, difference
- Reconciliation Detail — step-by-step reconciliation with each reconciling item
- Adjusting Entries Needed — journal entries required to correct the books
- Aged Items — reconciling items outstanding for more than one period
Output
The reconciliation written to .metapowers/accounting/$ARGUMENTS/reconciliation.md. Present a summary highlighting:
- Book balance vs. external balance and the difference
- Number and total of reconciling items
- Any required adjusting 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.

reconciliation is a skill published in the GitHub repository bromso/metapowers (1 stars, last pushed 4mo ago), licensed MIT. It adds 9 tokens to every session and 489 once invoked, about $0.0000 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.
