Every workflow is methodical, phase-numbered, and gated (missing artifacts fail the step); mathematical judgement is enforced through required evidence rather than through post-hoc review.\n\n## Sibling: [`MQSlim`](https://github.com/CBirkbeck/MQSlim)\n\nA [parallel slim plugin](https://github.com/CBirkbeck/MQSlim) that shadows this\none — same workflows, same load-bearing rails, restated in the \"trust frontier-\nmodel judgement; minimal instructions\" style Anthropic's skill-authoring guide\nexplicitly recommends. Load both together and pick per task by typing `/cleanup`\n(verbose, gated) vs. `/clnup` (slim). MQSlim tests the hypothesis that\nfrontier models produce better output when the prompts state the goal + the\ngates that catch real failures, and then get out of the way.\n\n## What It Does\n\n### Develop New Mathematics — Plan with `/develop`, then Execute with `/beastmode`\n\nThe development workflow is **split into planning and execution** to prevent the \"agent\nreconsiders the whole approach mid-proof\" failure mode. `/develop` does the strategic\nthinking; `/beastmode` does the tactical implementation; neither does the other's\njob.\n\n**`/develop` — planning only.**\n\n- **Comprehensive plan** from your references; exhaustive mathlib search; API design for every new declaration.\n- **One conclusion per declaration.** A result whose statement would bundle several independently-provable conclusions (a top-level `∧`-chain, source parts (i)/(ii)/(iii)) is split at planning time — one lemma per part, each with its own name and minimal hypotheses; any kept bundle is a one-line `⟨…⟩` assembly.
