method-evolution SKILL.md skillA
method-evolution from corvinlabs/corvinos is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when the same rubric violation, the same kind of symptom-patch, or the same escalation happens across 3+ distinct tasks — meaning the problem is in the method (skill, prompt, rubric), not in the tasks. Forces a disciplined outer-loop step: name the pattern, propose a skill/rubric change, measure Δloss before and after, roll back on regression.
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
# Method-Evolution ## Overview If your agent keeps making the same kind of mistake across completely different tasks, the mistake is not in the tasks — it's in the **method** that's instructing the agent. That means a skill is too vague, a rubric is too permissive, a prompt lets a rationalization slip through. Updating the task fixes *this* bug. Updating the method fixes the bug *and* prevents the next 10. **Core principle:** method-evolution is SGD on the **θ-axis** (the skills, prompts, rubrics themselves), not the inner-loop code axis or the refinement y-axis. It is the rarest and most load-bearing of the three loops — and the only one that can actually improve the bundle over time. See [`../../docs/ldd/convergence.md`](../../docs/ldd/convergence.md) §1 for the three-loop model and §3.4 for the "moving-target loss" anti-pattern that this skill prevents. ## When to Use Invoke **only** when **all** of: - You have observed the **same rubric violation / symptom-patch / escalation** in ≥ **3 distinct tasks** across different domains - The method's Red Flags list does not already cover this case - Patching each task individually would not prevent the next occurrence …

How to install
mdr add corvinlabs/corvinos/method-evolution@sha256:17e1089208ada93eThe line at the top of this page pins the label git:20260915.459047e, 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.
