rederive SKILL.md skillA

rederive from jongwony/epistemic-protocols is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add jongwony/epistemic-protocols/rederive@git:20261019.7bdc90e

Pins git:20261019.7bdc90e in mdr.lock. Pin the fingerprint instead.

This skill should be used when a contributor names a skill whose Lean contract is to be re-derived — a core protocol, or a utility skill whose formal block is or becomes Lean — or invokes /rederive. Runs the per-skill flow: gather the pre-understanding, derive the skill's epistemic solution and fuse it with the contributor's horizon, then read the current contract against it, through sketch, edit, dogfood, review, merge, the chart close and a retrospective on this skill. Project-local…

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

# Re-derive a protocol contract

One skill per run, whose formal block is Lean or becomes Lean in the run: a core protocol in `scripts/load-protocols.js` `CANONICAL_PROTOCOL_SET`, or a utility skill in `LEAN_CONTRACT_UTILITIES` there, which a utility still carrying a text-DSL block enters in its run. Below, *the protocol* names that skill whichever kind it is. The object is the protocol itself — its `SKILL.md` on `origin/main`; an open PR whose branch carries the chart id, where one exists, is one more piece of material, never the anchor. Anchor chart: the protocol's own `ROO-*` chart, which for a utility may be one chart several skills' runs share; suite-wide ground: ROO-67.

**What a re-derivation answers to.** The target is the morphism that the `AGENTS.md` Northstar and the premise axiom Context and Utterance as First-Class Ground (`premise/recognition-and-authority.md`) admit, in the form `lean/EpistemicProtocols/Ground.lean` fixes: the fused context — turns bound to who sent them — and the person's utterance are the ground; the structure fixes only what the harness knows; everything else is the model's inference, declared as a documented judgment inside the types.

How to install

The exact contents, by fingerprint
mdr add jongwony/epistemic-protocols/rederive@sha256:86e2727c86579a11

The line at the top of this page pins the label git:20261019.7bdc90e, 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.
