The skill was thorough but failed to instill debugging taste: an agent would pattern-match a symptom-table row to a fix and ship a guess, because the behaviour-changing material sat 550 lines down. Promote three gates to the top: - "Before you debug: calibrate" -- you're likely OOD in research code; the failure mode is overconfidence/impatience; the tables are a menu to widen the search, never lookup-and-apply. - "The debugging loop (judgment, not a checklist)" -- collect clues, hold a few competing hypotheses scaled to the problem, sanity-check with the likely/subtle/null triplet (shared vocab with research-journal), run the cheapest discriminating observation, then act. - "When stuck, read a working implementation" -- promoted from a buried Part 7.3 one-liner; extract the algorithm-done-right, the engineering tricks the paper omits, and proven hyperparams; rank candidates by trust signal. Collapse duplicated advice to pointers; de-bold Part 6.4 (8 bolded openers -> a plain list). Net +10 lines, bold markers 112 -> 100. Verified by a blind comprehension-by-inference quiz (5 cold-reader models, OLD vs NEW): NEW 9.6/10 vs OLD 6.8/10, with the gap localized to the two added sections (read-working-impl 5/5 vs 0/5; tables-as-menu 2.0 vs 1.6) while untouched sections tied -- ruling out a "reads nicer" halo.

ML Debugging Folklore
Practitioner knowledge for debugging ML systems, curated and synthesized by wassname. Opinionated by source selection -- I picked sources I trust (Schulman, Goodfellow, CS231n, ...) and had an LLM extract the most relevant information for debugging ML systems.
Use as a Claude skill
/skills add https://github.com/wassname/ml_debug
Or paste SKILL.md into your system prompt / context when debugging.
What's here
-
SKILL.md -- the main artifact. Load into an LLM agent's context as a debugging skill. Parts 1-5 are reference knowledge; Part 6 is a runnable triage protocol (grep patterns, diagnostic snippets, decision tree); Part 7 is debugging mental models and practitioner priors.
-
docs/evidence/ -- frozen local copies of source material (blog posts, talks, papers, reddit threads). Claims in SKILL.md link back to exact quotes here.
