Quality

Content

88%Weight 40%Scale 1-5

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

A well-structured, highly actionable debugging runbook with executable commands and a proper verify-fix loop. Its only notable weakness is a broken worked-example reference and minor trimmable asides.

Suggestions

Add the missing examples/react-reconciler-performance-measure-leak.md file referenced in the Worked Example section, or remove the reference.

Trim a few explanatory asides (e.g. the npm/tsx note) to the essential 'why' to lift conciseness.

Consider moving the long retainer-class pattern list in Step 5 to a references file to keep SKILL.md an overview.

Dimension	Reasoning	Score
Conciseness	Mostly efficient with concrete commands and justified notes (e.g. why QWEN_CODE_NO_RELAUNCH matters); a few explanatory asides could be trimmed, placing it above the 'mostly efficient' 3 but not at the fully lean 5.	4 / 5
Actionability	Provides copy-paste ready bash commands for every step with clearly explained placeholders (e.g. '<uid>' sourced from get_memory_snapshot_details output), covering the common diagnostic cases fully.	5 / 5
Workflow Clarity	A clearly sequenced 6-step process with an explicit validation/feedback loop in Step 6 ('Repeat Steps 1-4', 'Confirm the leaking class count stabilizes') and a cleanup section.	5 / 5
Progressive Disclosure	Good section structure with one-level references to a real helper script (scripts/find-leaf-node.sh) and the tmux-real-user-testing skill; however the worked-example reference (examples/react-reconciler-performance-measure-leak.md) points to a file that is not present in the bundle, a minor organization gap keeping it below 5.	4 / 5

Description

82%Weight 40%Scale 1-5

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 focused, well-formed description that clearly states both the capability and explicit trigger conditions in third person. It is highly distinct and complete, with only slightly limited action enumeration keeping specificity from the top anchor.

Dimension	Reasoning	Score
Specificity	Names the domain ('memory leaks in the Qwen Code CLI') and 1-2 concrete actions ('heap snapshots', 'chrome-devtools CLI'), but does not enumerate multiple distinct actions, so it stops at the 'names domain and 1-2 concrete actions' anchor rather than the comprehensive 5.	3 / 5
Completeness	Explicitly answers both 'what' ('Diagnose memory leaks in the Qwen Code CLI using heap snapshots and the chrome-devtools CLI') and 'when' ('Use when investigating high memory usage, unbounded growth, or suspected object retention issues') with concrete trigger phrases.	5 / 5
Trigger Term Quality	Includes natural phrases a user would say ('high memory usage', 'unbounded growth', 'suspected object retention issues') with good coverage; a few common synonyms (e.g. 'OOM', 'memory pressure') are missing, keeping it just below the comprehensive 5.	4 / 5
Distinctiveness Conflict Risk	The narrow scope (Qwen Code CLI + heap snapshots + chrome-devtools) gives it a clear niche with distinct triggers and minimal overlap risk with other skills.	5 / 5
