m-iteration from csalcedodatabi/powerquery-m-for-agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add csalcedodatabi/powerquery-m-for-agents/m-iteration@git:20261001.aec5b2cPins git:20261001.aec5b2c in mdr.lock. Pin the fingerprint instead.

Use when a Power Query M task needs looping or state across rows — List.Generate, List.Accumulate, running totals, paginating a REST API until the last page, Table.Buffer or List.Buffer to stop repeated evaluation, GroupKind.Local for sorted groups, or deciding between these for performance. Triggers on "loop in Power Query", "List.Generate", "List.Accumulate", "pagination Power Query", "running total M", "Table.Buffer", "List.Buffer", "GroupKind.Local", "iterate API pages".
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
# M Iteration > **Status.** Stub. Scope fixed in > [the design spec](../../docs/superpowers/specs/2026-09-28-powerquery-m-for-agents-design.md) > (§4). ## Planned contents | File | Covers | |---|---| | `references/list-generate.md` | The four arguments, the off-by-one on the last page, returning records as state | | `references/list-accumulate.md` | When it is fine and when it is quadratic | | `references/buffering.md` | `Table.Buffer` / `List.Buffer`: what they fix, and that they stop folding | | `references/pagination.md` | Next-link, offset and cursor pagination patterns | | `references/group-local.md` | `Table.Group(..., GroupKind.Local)` on sorted data | ## Related skills - **`m-reference`** — signatures. - **`m-folding`** — buffering ends folding; know the trade.

How to install
mdr add csalcedodatabi/powerquery-m-for-agents/m-iteration@sha256:310852d7698ecb28The line at the top of this page pins the label git:20261001.aec5b2c, 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.
