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

Use at the start of any conversation, and whenever the user mentions LDD, loss-driven development, loss, gradient, SGD on code, drift, refinement loop, outer loop, inner loop, method evolution, or says "LDD:" / "apply LDD". Establishes how to dispatch the ten LDD skills and when each fires. Must be the first skill considered in any coding task where LDD is available.
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
# Using LDD — the bundle entry-point ## Overview Loss-Driven Development (LDD) is a ten-skill bundle that treats code changes as SGD steps and forbids overfitting to the current test. This entry-skill exists so you (the agent) know **when to reach for which LDD skill** without the user having to name each one by hand. **Core principle:** if the user prefixes their message with `LDD:` or mentions any of the trigger phrases below, LDD discipline is explicitly requested. Match their intent to the right sub-skill and announce which one you are applying. ## Trigger phrases (user → skill mapping) When the user's message contains any of these patterns, invoke the paired skill. | User signal | Invoke | |---|---| | `LDD:` prefix, "apply LDD", "use LDD" | Enter full LDD mode — default entry = `loop-driven-engineering` unless a more specific sub-skill matches below | | "failing test", "CI is red", "flaky", "one-off failure", "intermittent" | First `reproducibility-first`, then `root-cause-by-layer` if the failure is real | | "bug", "error", "exception", "unexpected behavior", "why is this breaking" | `root-cause-by-layer` | …

How to install
mdr add corvinlabs/corvinos/using-ldd@sha256:a238e3006e505980The 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.
