iterative-refinement SKILL.md skillA
iterative-refinement from corvinlabs/corvinos is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add corvinlabs/corvinos/iterative-refinement@git:20260915.459047ePins git:20260915.459047e in mdr.lock. Pin the fingerprint instead.

Use when a deliverable (document, diff, design, report, code module) is complete but "good enough, not great" and you want to improve it with a targeted re-iteration instead of starting over. Forbids re-running the task from scratch when refinement is more efficient. Operates on the y-axis (output) not the θ-axis (code or method).
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
# Iterative-Refinement ## Overview Most agents, when told "this is okay but can be better," do one of two wrong things: 1. **Re-run the task from scratch.** Wastes budget, loses whatever was good in the first attempt, gambles on random variation. 2. **Polish by gut feel.** No loss signal, no gradient, no stopping criterion. Converges to the agent's aesthetic prior, not to a better deliverable. **Core principle:** refinement is a *second* gradient-descent pass, on the **y-axis** (the deliverable itself), using a **specific gradient** derived from the previous output's defects. The inputs, the task, the code, the skills — all held fixed. Only the deliverable changes. This is the skill-level equivalent of `awp refine` (AWP's normative refinement mode). See [`../../docs/ldd/convergence.md`](../../docs/ldd/convergence.md) §1 for the three-loop model. ## When to Use Invoke when **all** of: - A deliverable (document, code module, design artifact, plan) is **complete** (not partial, not stuck) - The deliverable is **usable but imperfect** — passes the minimum bar, fails the bar you actually want …

How to install
mdr add corvinlabs/corvinos/iterative-refinement@sha256:b2b72754b1e7b433The 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.
