reconciliation

reconciliation is a skill for Claude Code from alebgl77/claude-inc. It costs 97 tokens per session (1,120 once invoked), scanned A, original, MIT.

A data-matching tool that compares two lists which should agree, such as a bank statement and an accounting ledger. It can match exact values, near matches, and transactions split across multiple records.

In plain words
What is it for?
Use it for bank reconciliations, accounts-receivable checks, payment-processor payouts, intercompany balances, and other two-list comparisons.
Why use it?
It explains differences without manually checking long columns and groups unmatched records into clear exception types.

Token cost

What it costs to keep this loaded

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.

Security

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 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.

Reconciliation — Reconciler

"Reconcile the books."

When to use

  • Bank vs ledger — "reconcile June's bank statement against GL cash".
  • Subledger vs GL — "the AR subledger says 412k, the GL says 405k — why?".
  • Processor vs books — "match Stripe payouts to booked revenue".
  • Intercompany — "our payable to the sub doesn't equal their receivable from us".
  • Any two lists that should agree and don't.

Workflow

  1. Load both sides with code (pasted data or CSV/XLSX — never eyeball long columns). Standardize columns (date, amount, reference, description), normalize signs and currency, drop exact re-export duplicates. Record each side's row count and total — these anchor the bridge.
  2. Exact pass. Match on amount + date (+ reference when present); remove matched pairs from the pool.
  3. Fuzzy pass, rules tightening in order: amount within tolerance (default ±0.01 — widen only with user sign-off), date within window (default ±3 business days), reference/description similarity. Log every fuzzy match with the rule that made it.
  4. One-to-many pass. Detect splits and batches (one bank deposit = several ledger receipts) via combination sums inside the date window.
  5. Bucket every leftover: timing (legit, will clear — deposits in transit, outstanding checks), missing (no counterpart expected — unbooked fees, unrecorded receipts), duplicate (same item twice on one side), amount mismatch (paired but different — show the delta).
  6. Age the unmatched by days outstanding: 0–7, 8–30, 31–60, 60+. Anything over 30 days gets a priority flag.
  7. Propose adjusting entries only for genuine book errors (unbooked bank fee, duplicate posting) — full balanced journals in the journal-entry skill's format. Timing items never get forced adjustments.
  8. Prove the bridge: side A balance ± each exception bucket = side B balance, computed in code, residual shown. Target 0.00; anything else is stated, never hidden.

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.
