model-pruning

Reduce LLM size and accelerate inference using pruning techniques like Wanda and SparseGPT. Use when compressing models without retraining, achieving 50% sparsity with minimal accuracy loss, or enabling faster inference on hardware accelerators. Covers unstructured pruning, structured pruning, N:M sparsity, magnitude pruning, and one-shot methods.

Quality

Content

50%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A content-rich, code-heavy skill that is genuinely actionable in its headline examples but suffers from internal redundancy, undefined helper placeholders in the strategies/pipeline code, and a lack of validation checkpoints in the destructive pruning workflow. The unused wanda.md reference indicates progressive-disclosure structure that was not wired up.

Suggestions

Link and defer to references/wanda.md for the deep Wanda treatment, and move Core Concepts / Strategies / Performance Comparison into reference files so the body becomes a lean overview with one-level-deep, clearly signaled links.

Replace or define the placeholder helpers (load_calibration_data, prune_layer, train_step, fine_tune, prune_model) and fix the non-executable 'importance = weight^2 / diag(Hessian)' so every code block is copy-paste runnable, and add the missing `from datasets import load_dataset` import.

Add an explicit validation checkpoint to the pruning pipeline (e.g., verify sparsity level and run a quick perplexity/eval probe on calibration data before saving) so the destructive weight-mutation step has a validate-then-proceed feedback loop.

Dimension	Reasoning	Score
Conciseness	The ~485-line body is mostly code and not padded with concepts Claude already knows, but it repeats the same technique across Quick Start, Core Concepts, and Best Practices (e.g., the Wanda \|weight\|×activation criterion appears three times) and could be tightened; not the 'lean, every token earns its place' anchor.	2 / 3
Actionability	The centerpiece Wanda and N:M snippets are executable and copy-paste ready, but several examples rely on undefined placeholders — load_calibration_data(), prune_layer(), train_step(), fine_tune(), prune_model(), the un-imported load_dataset(), and the non-Python 'importance = weight^2 / diag(Hessian)' — so key details are missing.	2 / 3
Workflow Clarity	The production pipeline gives a numbered 1–5 sequence, but pruning mutates model weights (a destructive/batch-style operation) with no mid-workflow validation checkpoint before saving; the post-hoc Evaluation comparison does not satisfy the explicit validate-then-proceed feedback loop the top anchor requires.	2 / 3
Progressive Disclosure	Sections provide structure, but the file is a monolithic ~485-line wall with Core Concepts, Strategies, and Performance Comparison inlined that could be split out, and the existing references/wanda.md bundle file is never linked or signaled from the body.	2 / 3

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that states concrete capabilities, provides an explicit 'Use when' trigger with multiple natural conditions, and carves out a distinctive niche. Voice is correctly third person, so no specificity penalty applies.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'Reduce LLM size', 'accelerate inference', 'compressing models without retraining', 'achieving 50% sparsity' — plus an enumerated coverage list (unstructured, structured, N:M, magnitude, one-shot), matching the 'lists multiple specific concrete actions' anchor.	3 / 3
Completeness	Clearly answers both 'what' (reduce LLM size / accelerate inference via pruning techniques) and 'when' with an explicit 'Use when compressing models without retraining, achieving 50% sparsity..., or enabling faster inference...' trigger clause, satisfying the highest anchor.	3 / 3
Trigger Term Quality	Contains natural user-facing terms like 'compressing models', 'faster inference', 'pruning', 'sparsity', and 'hardware accelerators' alongside the named techniques; good coverage of phrasing a user would naturally say when they need this skill.	3 / 3
Distinctiveness Conflict Risk	Occupies a clear niche (LLM pruning/compression) anchored by distinctive named techniques (Wanda, SparseGPT, N:M sparsity) and specific triggers, making it unlikely to fire for an unrelated skill.	3 / 3
