Resumen
Use when the user wants an iterative, self-checking exploratory analysis of a dataset — surfacing findings that are each verified by re-running the computation, not asserted. Proposes one specific hypothesis at a time, writes and runs analysis code to test it, and records the finding only if the numbers support it at a meaningful effect size; loops until no new verified finding appears or the budget is hit. The result is a findings report where every claim is backed by a reproducible number. Not for diagnosing a single known anomaly or pipeline failure, and not for verifying an external claim against sources (that is a claim-verification task) — this is open-ended discovery over a bound dataset.

Data Analysis Loop
A hypothesis → verify reflection loop over a dataset. The artifact is a findings report; the feedback signal is verification — a finding only counts if re-running the computation confirms it at a meaningful effect size. The discipline this enforces: no insight without a number behind it. A plausible claim the data does not support is discarded, not softened; every line in the report can be reproduced from the dataset.
When to use
Use this for open-ended, self-checking exploration of a bound dataset where each finding must survive an independent re-computation. Default to broad exploration across the columns; if the user gives a focus question, let it steer the hypotheses. Not for diagnosing one known anomaly or for checking an external claim against the literature.
Setup
Resolve bindings interactively. If loop.run.yaml exists in the working dir, load it, confirm the
values in one line, and skip to the loop. Otherwise: on Claude Code (the AskUserQuestion tool is
available) infer a likely value for each binding and present it as the recommended option; on other
hosts ask each as a quoted plain-text prompt. Then write loop.run.yaml (format:
examples/run.example.yaml) and confirm the values before creating any other files.
| binding | meaning | default | how to infer |
|---|---|---|---|
<dataset> | data file to analyze (CSV/TSV/Parquet/…); read-only ground truth | — | scan the working dir for a data file |
<question> | optional analysis focus; omit to explore broadly | — | ask the user; else leave unbound |
<report> | output findings file | <sandbox_root>/findings.md | — |
<analysis_cmd> | interpreter that runs analysis snippets in the user's env | python3 | pyproject.toml/.venv/uv in the working dir |
<sandbox_root> | where snippets + ledger live | ./sandbox | — |
<budget> | max iterations | 8 | — |
<patience> | stop after N consecutive iters with no new verified finding | 2 | — |
Analysis snippets run in the user's environment via <analysis_cmd>, so they may use whatever the
user has installed. Keep helper code stdlib-first (csv, statistics): if a snippet needs
pandas/numpy, probe with try/except ImportError and degrade to a stdlib path, or offer a
consented uv pip install "pandas==<ver>" — never assume the package is installed.
The loop
Copy this checklist and tick items off:
- Iteration 0 — profile
<dataset>(shape, types, ranges, missingness); record nothing as a finding. - Propose one specific, checkable hypothesis (steered by
<question>; not already settled). - Compute it: write
<sandbox_root>/iter<N>/analysis.py, run with<analysis_cmd>, redirect toout.txt. - Verify: re-derive the key number a second way; judge against a stated effect-size bar.
- Supported → append finding to
<report>(verified); else logrefuted, do not add it. - Append a ledger row; stop on plateau (
<patience>) or<budget>.
Iteration 0 — profile. Write and run a snippet that reports the shape of <dataset>: columns,
inferred types, row count, and a quick summary (ranges, category counts, missingness). This grounds
the hypotheses; record nothing as a finding yet.
Then, until stop (dry or budget):
- Propose one hypothesis. A single, specific, checkable claim — e.g. "enterprise orders average
higher value than consumer", "mobile has a higher return rate than other channels", "order value
rises with signup tenure". Let
<question>steer it; do not repeat a hypothesis already settled. - Compute it. Write
<sandbox_root>/iter<N>/analysis.pythat loads<dataset>and computes the relevant statistic plus an effect size (a group-mean difference, a rate gap, a correlation — not just a yes/no). Run it with<analysis_cmd>, redirecting output to<sandbox_root>/iter<N>/out.txt(never flood your context). - Verify — the gate. Re-derive the key number a second, independent way (a different grouping, a
recount, or a sanity cross-check) and confirm the two agree. Then judge honestly: does the result
support the hypothesis at a meaningful effect size, or is it negligible / within noise? Decide
"meaningful" against a bar you state up front and apply consistently — a minimum effect size scaled
to the group sizes and noise (e.g. roughly |Cohen's d| ≳ 0.2, risk ratio ≳ 1.5, or |r| ≳ 0.1,
tightened when groups are small) — so the keep/refute threshold does not drift between iterations.
- Supported → append a finding to
<report>: the claim, the exact numbers, the effect size, and the method (so it is reproducible). Mark itverified. - Not supported / negligible → record it as
refutedin the ledger and do not add it to the report. A null result is a real outcome, not a failure to hide.
- Supported → append a finding to
- Log one ledger row and continue.

3 mobile has a higher return rate than web/store 0.30 vs 0.10 verified
Report the best outcome: the <report> path, the count of verified findings, and the hypotheses
refuted (so the user sees what was checked and ruled out, not just what survived).
Constraints
- No claim without a computed number. Every finding in
<report>carries the figures and the method that produced it; if you cannot compute it, you cannot claim it. - Verify before recording. The independent re-derivation in step 3 is the gate — a finding that does not reproduce, or whose effect is within noise, does not enter the report.
- Report effect sizes, not just direction, and do not inflate a correlation into a causal claim — say "associated with", and note confounders when the data cannot separate them.
- One hypothesis per iteration, so each finding is attributable, and skip hypotheses already settled.
- Only read

# Data Analysis Loop
A **hypothesis → verify** reflection loop over a dataset. The artifact is a findings report; the
feedback signal is **verification** — a finding only counts if re-running the computation confirms it
at a meaningful effect size. The discipline this enforces: **no insight without a number behind it.**
A plausible claim the data does not support is discarded, not softened; every line in the report can
be reproduced from the dataset.
## When to use
Use this for open-ended, self-checking exploration of a bound dataset where each finding must survive
an independent re-computation. Default to broad exploration across the columns; if the user gives a
focus question, let it steer the hypotheses. Not for diagnosing one known anomaly or for checking an
external claim against the literature.
## Setup
Resolve bindings interactively. If `loop.run.yaml` exists in the working dir, load it, confirm the
values in one line, and skip to the loop. Otherwise: on Claude Code (the `AskUserQuestion` tool is
available) infer a likely value for each binding and present it as the recommended option; on other
hosts ask each as a quoted plain-text prompt. Then write `loop.run.yaml` (format:
`examples/run.example.yaml`) and confirm the values before creating any other files.
| binding | meaning | default | how to infer |
|---|---|---|---|
| `<dataset>` | data file to analyze (CSV/TSV/Parquet/…); read-only ground truth | — | scan the working dir for a data file |
| `<question>` | optional analysis focus; omit to explore broadly | — | ask the user; else leave unbound |
| `<report>` | output findings file | `<sandbox_root>/findings.md` | — |
| `<analysis_cmd>` | interpreter that runs analysis snippets in the user's env | `python3` | `pyproject.toml`/`.venv`/`uv` in the working dir |
| `<sandbox_root>` | where snippets + ledger live | `./sandbox` | — |
| `<budget>` | max iterations | 8 | — |
| `<patience>` | stop after N consecutive iters with no new verified finding | 2 | — |
Analysis snippets run in the **user's environment** via `<analysis_cmd>`, so they may use whatever the
user has installed. Keep helper code **stdlib-first** (`csv`, `statistics`): if a snippet needs
`pandas`/`numpy`, probe with `try/except ImportError` and degrade to a stdlib path, or offer a
consented `uv pip install "pandas==<ver>"` — never assume the package is installed.
## The loop
Copy this checklist and tick items off:
- [ ] Iteration 0 — profile `<dataset>` (shape, types, ranges, missingness); record nothing as a finding.
- [ ] Propose one specific, checkable hypothesis (steered by `<question>`; not already settled).
- [ ] Compute it: write `<sandbox_root>/iter<N>/analysis.py`, run with `<analysis_cmd>`, redirect to `out.txt`.
- [ ] Verify: re-derive the key number a second way; judge against a stated effect-size bar.
- [ ] Supported → append finding to `<report>` (`verified`); else log `refuted`, do not add it.
- [ ] Append a ledger row; stop on plateau (`<patience>`) or `<budget>`.
**Iteration 0 — profile.** Write and run a snippet that reports the shape of `<dataset>`: columns,
inferred types, row count, and a quick summary (ranges, category counts, missingness). This grounds
the hypotheses; record nothing as a finding yet.
**Then, until stop (dry or budget):**
1. **Propose one hypothesis.** A single, specific, checkable claim — e.g. "enterprise orders average
higher value than consumer", "mobile has a higher return rate than other channels", "order value
rises with signup tenure". Let `<question>` steer it; do not repeat a hypothesis already settled.
2. **Compute it.** Write `<sandbox_root>/iter<N>/analysis.py` that loads `<dataset>` and computes the
relevant statistic **plus an effect size** (a group-mean difference, a rate gap, a correlation —
not just a yes/no). Run it with `<analysis_cmd>`, redirecting output to
`<sandbox_root>/iter<N>/out.txt` (never flood your context).
3. **Verify — the gate.** Re-derive the key number a second, independent way (a different grouping, a
recount, or a sanity cross-check) and confirm the two agree. Then judge honestly: does the result
**support the hypothesis at a meaningful effect size**, or is it negligible / within noise? Decide
"meaningful" against a bar you state up front and apply consistently — a minimum effect size scaled
to the group sizes and noise (e.g. roughly |Cohen's d| ≳ 0.2, risk ratio ≳ 1.5, or |r| ≳ 0.1,
tightened when groups are small) — so the keep/refute threshold does not drift between iterations.
- **Supported** → append a finding to `<report>`: the claim, the exact numbers, the effect size,
and the method (so it is reproducible). Mark it `verified`.
- **Not supported / negligible** → record it as `refuted` in the ledger and do **not** add it to
the report. A null result is a real outcome, not a failure to hide.
4. **Log** one ledger row and continue.
## Ledger
`<sandbox_root>/ledger.tsv`, tab-separated, never commas in the text. Header:
```
iter hypothesis effect status
```
`status` ∈ {`profile`, `verified`, `refuted`}. Example:
```
iter hypothesis effect status
0 dataset profile - profile
1 enterprise orders average higher value than consumer 185 vs 109 (+70%) verified
2 returns differ by region North 0.16 vs South 0.14 (negligible) refuted
3 mobile has a higher return rate than web/store 0.30 vs 0.10 verified
```
Report the **best** outcome: the `<report>` path, the count of verified findings, and the hypotheses
refuted (so the user sees what was checked and ruled out, not just what survived).
## Constraints
- **No claim without a computed number.** Every finding in `<report>` carries the figures and the
method that produced it; if you cannot compute it, you cannot claim it.
- **Verify before recording.** The independent re-derivation in step 3 is the gate — a finding that
does not reproduce, or whose effect is within noise, does not enter the report.
- **Report effect sizes, not just direction**, and do not inflate a correlation into a causal claim —
say "associated with", and note confounders when the data cannot separate them.
- **One hypothesis per iteration**, so each finding is attributable, and skip hypotheses already settled.
- **Only read `<dataset>`** — never modify it, because it is the ground truth every finding is checked
against. The sandbox is self-contained (no `../` escapes).
- Do not pause the loop to ask whether to continue; run until it goes dry or hits the budget.
## Stops
- **Dry** — `<patience>` consecutive iterations add no new verified finding.
- **Budget** — `<budget>` iterations reached.
