Prepare an unadjusted trial balance from the general ledger and verify that total debits equal total credits, tracing any error. Use when the user has posted the ledger and wants to check the books balance before making period-end adjustments. Not for balances after adjusting entries; see /accounting-adjusted-balance.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Trial Balance
Prepare an unadjusted trial balance for "$ARGUMENTS". List all ledger account balances and verify that total debits equal total credits.
**Arguments.** `$ARGUMENTS` may contain the project name and optional flags. Take the first token as `<project>` and treat `--skip-checks` as a flag; never include flags in file paths. All paths below use `<project>`. If `--skip-checks` is present, skip the prerequisite check and, **before writing any artifact**, append one line to `.singularskills/log.jsonl`: `{"ts":"<ISO timestamp>","skill":"accounting-trial-balance","workflow":"accounting","phase":4,"project":"<project>","event":"skipped","artifact":"04-trial-balance.md","note":"<reason or \"none given\">"}`.
**Compute with code.** Perform every calculation (totals, balances, ratios, variances, projections) with a script — Bash, Python or a spreadsheet formula written to a file — and include the computation alongside the result. Never do arithmetic mentally.
## Prerequisites
…Read the whole file at its exact version.
How to install
mdr add bromso/singularskills/accounting-trial-balance@sha256:a0cc3b0f8a35a5b8The line at the top of this page pins the label git:20261029.7f379ee, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
