name eiffel-research description Pre-Phase research for new simple_* libraries. 7-step investigation process before design. Use when starting a new library idea. Produces research output for /eiffel.spec. allowed-tools Read, Grep, Glob, Edit, Write, Bash, Task, WebSearch, WebFetch
/eiffel.research - Pre-Phase: Deep Research
Purpose: Systematically research a new library idea BEFORE design. Transforms a vague idea into validated requirements.
When to Use
New simple_ libraryMajor feature - Before adding significant capabilityTechnology selection - Choosing between approachesProblem unclear - When the problem space needs exploration
Usage
/eiffel.research <project-path>
Example:
/eiffel.research d:\prod\simple_cache
CRITICAL: Anti-Slop Rules
This workflow requires ACTUAL:
Web searches with real URLs (WebSearch/WebFetch tools)
Documentation written to actual files
Sources cited with actual URLs
FORBIDDEN:
Making up library names or features
Citing documentation without actual URLs
Claiming "research complete" without written deliverables

Context Management (RLM Pattern)
Use WebSearch and WebFetch for actual research
Use Task tool with Explore agent for ecosystem questions
Write findings to actual files as you go
Make up library names or features
Cite URLs without actually fetching them
Skip steps or claim research without evidence
Research Quality Criteria Step Criterion Scope Problem clearly stated, boundaries defined Landscape At least 3 alternatives researched with real URLs Requirements Prioritized with acceptance criteria Decisions Options evaluated, rationale recorded Innovations Differentiation clearly stated Risks Identified with mitigations Recommendation Clear, evidence-based, actionable
Anti-Drift
Every claim needs evidence - URLs, code samples, actual dataNo imaginary libraries - Only cite what actually existsResearch before recommend - Don't skip to conclusionssimple_ first
