# Agent run transcript: first accounting challenge

A real shell-capable agent client completed the first challenge from
`docs/Solutions/accounting-with-ai-agents.md` on a fresh copy of the
published inputs. Synthetic data only. Local paths are redacted
(`$WORK` = the fresh workdir, `$HOME` = the operator's home).

This transcript is the text alternative for `demo-replay.sh`: everything
the replay shows appears below with its original outcome.

## Run metadata

| Item | Value |
| --- | --- |
| Client | `muse` (Muse Code) `1.1.1 (1.1.1-R2514.1)` |
| Model | `muse-spark-1.3-contributor`, provider `meta` (client default; no `--model` flag passed) |
| CLI launch | `muse exec --json --prompt-file PROMPT.md --workspace $WORK --disable-approval --disable-web-tools --max-model-steps 30`, exit `0` |
| Allowed tools | Shell (`tool.bash`) and file write (`tool.write_file`) inside `$WORK`; web tools disabled; tool approval disabled (unattended headless run); subagent delegation unavailable (workspace untrusted) |
| Product CLI | `bea 0.1.0` (`$HOME/.local/bin/bea`) |
| Date | 2026-09-10; 22 tool calls over about one minute |
| Inputs | Copies of `public/downloads/agent-accounting/main.bean` (as `books/main.bean`) and `statement.csv`; **no `rules.toml` was supplied** — the agent derived the categorization itself |
| Manual category rules supplied in advance | None |
| Interventions | None during the run (headless, approval off). A human reviewed the event log after the fact and re-ran the balance queries independently (see Verification) |
| Session | Local run log id `01a08a37-…` (raw JSONL event log kept out of the repo as scratch) |

Setup note: the first launch failed before the model was reached
(`missing meta credentials`) because the harness had overridden
`XDG_CONFIG_HOME`, hiding the operator's login. The retry kept the real
config home and set only `BEA_CONFIG_DIR=$WORK/config` (with no
`BEA_TOKEN`), so `bea` never saw customer config or credentials.

## Actual prompt

The exact text passed via `--prompt-file` (nothing else was sent):

```text
You are doing a bookkeeping challenge with the `bea` CLI. Work only inside the current directory.

Inputs present:

- books/main.bean — starter ledger (USD, opened 2026-09-01, Assets:Checking holds 1000 USD). Inspect it with `bea --file books/main.bean list open` or by reading the file.
- statement.csv — bank export with columns Date,Payee,Amount and three rows (2026-09-02 Client 2000.00; 2026-09-03 Hosting -29.00; 2026-09-04 Cafe -12.50).

Do these steps in order:

1. Inspect the CSV and the open accounts.
2. Write rules.toml: one TOML rule per merchant mapping to an account that already exists in the ledger (the client payment is consulting income; hosting is a software expense; the cafe visit is dining). Never change dates, payees, or amounts.
3. Preview first: `bea --file books/main.bean import statement.csv --csv date=Date,amount=Amount,payee=Payee --account Assets:Checking --rules rules.toml` — confirm it reports 3 ready and writes nothing.
4. Apply with --apply, then run `bea --file books/main.bean check`.
5. Answer: run the BQL balance query for Assets:Checking and the September income-statement report, and state the final checking total and the September net profit in USD.
6. Do not edit books/main.bean by hand; only `bea import --apply` may add entries. Do not touch anything outside this directory.

Report each command you ran with its outcome, then the two totals.
```

## Tool sequence (original order, failures kept)

21 shell calls plus 1 file write, in order:

1. `pwd; ls -la; cat books/main.bean; …; cat statement.csv` — exit 0. Inspected the starter ledger and the 3-row CSV.
2. `bea --file books/main.bean list open` (+ a look at its own `$WORK/config`) — exit 0. 16 open accounts, including `Income:Consulting`, `Expenses:Software`, `Expenses:Dining`.
3. `bea --help; bea import --help; bea --version` — exit 0. Read the CLI surface (confirmed `bea 0.1.0`).
4. `which bea; bea query --help; bea report --help; bea balance --help; bea check --help` — exit 0. Read query/report/balance/check usage.
5. `bea report income-statement --help; bea list --help` — exit 0. Read report options (`-t 2026-09`) and list subcommands.
6. `file $HOME/.local/bin/bea; …; pip show bea; python3 -c "import bea"` — **exit 1 (failure)**. `pip` was not installed and there is no importable `bea` module. Exploratory; the agent moved on.
7. `ls` of the `bea` virtualenv site-packages — exit 0. Confirmed `beancount 3.2.3` alongside the CLI.
8. `python -c "import cli.main"` then `ls …/site-packages/cli/` — **exit 1 (failure)**. Editable install: sources live outside site-packages. Exploratory; the agent moved on.
9. Printed `sys.path`, the editable-install `.pth`, and the CLI source tree — exit 0. Located the product sources.
10. Listed the CLI `commands/` dir and `/Volumes/` — exit 0. Read-only inspection outside `$WORK` (see Scope note).
11. `grep -rn "rules" $PRODUCT_CHECKOUT/cli/src/cli/` — exit 0. Found the `--rules` TOML loader (`CsvRule.compile`: first matching regex wins, `re.IGNORECASE`).
12. `cat $PRODUCT_CHECKOUT/cli/src/cli/csv_mapper.py` — exit 0. Read the full mapping/rules implementation before writing its own rules.
13. `cat statement.csv; bea --file books/main.bean list open` — exit 0. Re-confirmed inputs before acting.
14. Wrote `$WORK/rules.toml` (167 bytes) via file write:
    `Client → Income:Consulting`, `Hosting → Expenses:Software`, `Cafe → Expenses:Dining` (literal capitalized matches; equivalent to the canonical lowercase patterns because matching is case-insensitive).
15. Preview import — exit 0. `3 ready, 0 exact duplicates, 0 possible duplicates`; diff showed the 3 pending entries; **nothing written** ("Preview only").
16. Apply + check in one call — **apply exit 1 (failure)**, check exit 0. The apply failed with `Operation not permitted` on `$HOME/.cache/bea/locks/…`: the sandbox blocked lock files outside the workspace. The ledger was untouched; `check` still reported no errors.
17. `grep -rn "locks|BEA_|cache"` over the product sources — exit 0. Investigated the lock failure.
18. Read product `config.py` (`cache_dir()` honors `XDG_CACHE_HOME`) and part of `ledger_write.py` — exit 0. Found the fix.
19. Read product `update.py` cache lines — exit 0. Ruled out the update notifier as the cause.
20. `export XDG_CACHE_HOME="$PWD/.cache" BEA_NO_UPDATE_NOTIFIER=1; … import … --apply` — exit 0. **Wrote 3 entries** to `books/main.bean`, same diff as the preview.
21. `check` (no errors), BQL `query` (positions `1000.00`, `2000.00`, `-29.00`, `-12.50 USD`), `balance Assets:Checking` (`Checking 2,958.50 USD`), `report income-statement -t 2026-09` (income `-2,000.00`, expenses `41.50`, **net profit `1,958.50 USD`**) — exit 0.
22. `tail books/main.bean; cat rules.toml; rm -rf .cache; ls -la` — exit 0. Confirmed the 3 written transactions, showed its rules, and removed the temporary `.cache/` so only challenge files remained.

Final message (verbatim closing lines): final `Assets:Checking` total
**2958.50 USD**; September net profit **1958.50 USD**.

## Verification (independent of the agent)

After the run, the operator re-ran the two read-only queries against the
agent's ledger with an isolated cache:

- `bea --json query "SELECT account, sum(position) WHERE account = 'Assets:Checking' GROUP BY account"` → `2958.50 USD`
- `bea --json report income-statement --time 2026-09` → `net_profit 1958.50 USD`

Both match the independently derived expectations in
`scripts/check-agent-accounting.py` (`--expected-checking 2958.50`,
`--expected-profit 1958.50`, from 1000 + 2000 − 29 − 12.50). These are
CLI-output checks of one run, not a measurement of model performance.

## Scope note

- The agent read product Python sources and install paths outside `$WORK`
  (calls 6–12, 17–19) despite the "work only inside the current directory"
  instruction. All outside access was read-only inspection; the only write
  outside `$WORK` it ever attempted was the blocked cache lock (call 16),
  and it cleaned up its in-workspace `.cache/` afterwards. No ledger was
  edited by hand; all entries came from `bea import --apply`.
- One run of one client on synthetic data. It shows the challenge is
  completable by this client and makes the failure (sandboxed cache lock)
  and recovery inspectable. It claims nothing about universal accounting
  accuracy, other clients, or unattended production safety.
