Run deep, multi-agent work as adversarially verified workflows: repo audits, branch reviews, migrations, fleets. Explains the /effort ultracode toggle and launches the bundled Commander workflows. Use when the user types /ccc-ultracode or wants depth over speed on repo-wide work.

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

# /ccc-ultracode — depth over speed

**CC Commander** · /ccc-ultracode · substantial tasks run as multi-agent workflows whose findings are cross-checked before they reach you.

The strongest form of `rules/workflow-first.md`: delegate the doing, keep the deciding. Orchestration is the platform's Workflow tool; Commander supplies the scripts and the pickers.

## Two separate dials

| Dial | Command | Effect |
|---|---|---|
| Ultracode | `/effort ultracode on` · `/effort ultracode off` | Claude plans a dynamic workflow (fan out, verify adversarially, synthesize) for each substantial task instead of a single-agent pass. Its own toggle since Claude Code 2.1.284; it does not change the reasoning level. |
| Reasoning effort | `/effort xhigh` (or `high`, `max`) | How long the model thinks per turn. `max` lasts only for the current session. |

Both are typed by the user; this skill cannot flip them. Treat ultracode as a per-session choice and turn it off with `/effort ultracode off` when the deep work is done. Check the current state with `/effort`.

How to install

The exact contents, by fingerprint

mdr add kevinzai/commander/ccc-ultracode@sha256:8fdf80754723e5ee

The line at the top of this page pins the label git:20261025.7eae921, 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.
