SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Non-obvious technical insights discovered during debugging or design work are often lost once a session ends, leaving no record of why a solution worked. This Skill preserves those breakthroughs as structured, searchable Markdown documents before the context evaporates. ## Core Features & Use Cases - Structured Capture: Prompts for Problem, Insight, Implementation, and Impact, then writes a dated document to docs/breakthroughs/YYYY-MM-DD-<slug>.md with Date, Tags, and Project metadata. - Quality Bar: Applies a "would this surprise a senior engineer?" filter so routine fixes and well-documented knowledge are excluded, keeping the archive high-signal. - Convention Promotion: When an insight implies a reusable pattern, it proposes an update to the relevant rules/ file so one-off discoveries can become team conventions. - Use Case: After discovering that a retry storm was caused by clock skew between pods rather than backoff configuration, trigger the skill to record the insight with its root cause and quantified impact for future reference. ## Quick Start Ask the assistant to capture a breakthrough by saying "key insight: the retry storm was caused by clock skew between pods, not the backoff config" and answer the prompts for problem, insight, implementation, and impact.

Frequently Asked Questions about eureka

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I document a technical breakthrough or key insight?▼

Trigger the skill with /eureka or a phrase like "key insight" or "document discovery". It prompts for Problem, Insight, Implementation, and Impact, then writes a structured Markdown file to docs/breakthroughs/ with a date-based filename.

What qualifies as a breakthrough worth documenting?▼

The bar is whether the insight would surprise a senior engineer. Routine debugging, well-documented knowledge, and vague restatements of the problem do not qualify; the insight section must be specific enough to be actionable.

Where are breakthrough documents stored?▼

Documents are written to docs/breakthroughs/YYYY-MM-DD-<slug>.md with a header containing Date, Tags, and Project fields. This is an interim location until a cross-IDE memory architecture ships.

When should I use reflection instead of eureka?▼

Use reflection for recurring mistakes and session patterns rather than one-off discoveries. Eureka is for singular non-obvious insights, while reflection handles repeated failure patterns that need systematic correction.

Can a captured insight become a team convention?▼

Yes. If the insight implies a reusable convention, the skill optionally proposes an update to the relevant rules/ file so the discovery can be enforced as a standing engineering standard.
