Skill: javascript - Advanced JavaScript Engineering

Purpose

Provide advanced JavaScript guidance across runtimes, focusing on modern language features, performance optimization, and robust async patterns.

File Structure

forge-plugin/skills/javascript/ ├── SKILL.md └── examples.md

Interface References

• Context: Load guidance via ContextProvider Interface

• Memory: Store project knowledge via MemoryStore Interface

• Output: Save reports to /claudedocs/ using OUTPUT_CONVENTIONS.md

Mandatory Workflow

Step 1: Initial Analysis

• Identify runtime (Node.js, browser, edge) and deployment constraints

• Confirm module system (ESM/CJS) and bundler/tooling

• Capture performance goals and latency budgets

Step 2: Load Memory

• Use memoryStore.getSkillMemory("javascript", "{project-name}") to load prior decisions

• Review cross-skill notes via memoryStore.getByProject("{project-name}")

Step 3: Load Context

• Use contextProvider.getDomainIndex("engineering") to select relevant guidance

• Load only the context files required for the task

Step 4: Perform Analysis

• Review async patterns (promise chains, async/await, streaming)

• Evaluate module boundaries, dependency graphs, and bundling strategy

• Identify performance optimizations (event loop, caching, memory usage)

• Address runtime-specific security and stability concerns

Step 5: Generate Output

• Provide code samples, optimization plans, and rollout steps

• Save the report to /claudedocs/javascript_{project}_{YYYY-MM-DD}.md following OUTPUT_CONVENTIONS

Step 6: Update Memory

• Record runtime constraints, module strategies, and performance baselines

• Update memory with memoryStore.update("javascript", "{project-name}", ...)

Compliance Checklist

• Step 1 captured runtime and tooling constraints

• Step 2 loaded project memory via MemoryStore

• Step 3 loaded relevant context via ContextProvider

• Step 4 analysis covered async patterns and performance

• Step 5 output saved to /claudedocs/ with correct naming

• Step 6 memory updated with new insights
