This is a strong skill description that clearly articulates what the skill does (scan code changes and update specific Markdown context files) and when to use it (after implementation tasks, when syncing docs with code). It uses natural trigger terms, provides specific details about the target files and process, and occupies a distinct niche that minimizes conflict with other skills.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions: scans modified code, classifies change significance, updates/verifies Markdown context files. Also enumerates specific file types: overview, architecture, glossary, patterns, context-map, and domain files under `context/`.	3 / 3
Completeness	Clearly answers both 'what' (scans modified code, classifies change significance, updates Markdown context files) and 'when' (explicit 'Use when' clause covering updating docs after code changes, syncing docs, refreshing context, keeping memory files accurate).	3 / 3
Trigger Term Quality	Includes strong natural trigger terms users would say: 'update project documentation', 'sync docs with code', 'refresh project context', 'keep AI memory files accurate', 'implementation task'. These cover multiple natural phrasings a user might use.	3 / 3
Distinctiveness Conflict Risk	Highly distinctive with a clear niche: updating AI memory/context Markdown files under `context/` to reflect code changes. The specific mention of 'durable AI memory', `context/` directory, and the enumerated file types (glossary, patterns, context-map) make it unlikely to conflict with general documentation or code skills.	3 / 3

Implementation

62%

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

This is a well-structured process skill with a clear workflow, good classification gating, and a helpful concrete example. Its main weaknesses are the lack of executable tooling (no scripts or commands to automate the sync pass) and some redundancy between sections. The skill would benefit from tighter language and potentially splitting reference material into separate files.

Suggestions

Add concrete tool usage examples—e.g., show the exact sequence of file reads/writes Claude should perform, or provide a checklist template Claude can fill in during the sync pass.

Reduce redundancy by consolidating the 'feature existence' requirement mentioned in both step 6 and the final-task section into a single authoritative location.

Consider extracting the Classification Reference table and Domain File Creation Policy into separate bundle files to improve progressive disclosure and keep the main skill leaner.

Dimension	Reasoning	Score
Conciseness	The skill is reasonably efficient but includes some redundancy—the classification reference table partially restates the gating section, and some points (like 'ensure feature existence') are repeated across the workflow and final-task requirement. Overall it respects Claude's intelligence but could be tightened by ~20%.	2 / 3
Actionability	The workflow steps are clearly sequenced and the before/after example with the PaymentGateway is concrete and helpful. However, the skill is primarily procedural guidance without executable commands or scripts—there's no tooling, no CLI commands, no automation. The classification criteria are illustrative but somewhat subjective ('cross-cutting behavior') without precise heuristics.	2 / 3
Workflow Clarity	The 9-step workflow is clearly sequenced with a classification gate upfront, explicit verify-vs-edit branching, and a final check step that includes concrete constraints (250 lines, relative paths, diagrams). The before/after example demonstrates the expected outcome. The verify-only path still requires verification of root files, which serves as a validation checkpoint.	3 / 3
Progressive Disclosure	The skill uses internal anchors (Classification Reference, Domain File Creation Policy) for navigation within the document, which is good structure. However, with no bundle files, all content is inline in a single file. The domain file policy and classification reference could potentially be split out for better progressive disclosure, though the total length is manageable.	2 / 3
