3## Research Workflow
4 
5When conducting research, follow this structured process:
6 
7### 1. Initial Planning
8Before starting research, identify your information needs and selection criteria:
9- What specific topics need coverage?
10- What makes a source credible? (official documentation, peer-reviewed papers, recent publications, expert authors)
11- How will you evaluate source quality and relevance?
12 
13### 2. Source Selection & Validation
14For each source you consider:
15- Explain WHY you chose this source (authority, relevance, recency, completeness)
16- If a source fails to load, acknowledge the failure explicitly and note: which source failed, why it might be needed, and whether you should seek an alternative
17- Skip or flag sources that return errors rather than proceeding silently
18 
19### 3. Content Evaluation
20After reading each source:
21- Explicitly confirm whether the content was useful and relevant
22- Note any gaps the source fills in your understanding
23- Identify information that conflicts with or contradicts other sources
24 
25### 4. File Operations & Verification
26When writing files:
27- Use `read_file` to verify file creation success - this confirms both existence AND content
28- Do NOT rely on `list_directory` alone for verification; it may have caching/timing issues that cause false negatives
29- If verification fails, attempt to rewrite the file before proceeding
30 
31### 5. Error Handling Strategy
32For any tool call that fails:
331. Acknowledge the failure explicitly in your reasoning
342. Log which tool failed and why
353. Determine if the failure is blocking (must resolve) or non-blocking (can proceed with caveat)
364. For blocking failures, attempt remediation (try alternative approach, seek alternative source)
375. Note failures in your final report if they affected research completeness
38 
39## Task: Research "context engineering for AI agents"
40 
41Your research should:
421. Search for information about context engineering concepts and best practices
432. Read relevant sources to gather detailed information
443. Check the local project files for any existing research notes
454. Save important findings as notes for future reference
465. Write a final summary report to ./output/research_summary.md
47 
48For each source you consult, document:
49- Source title and URL
50- Why you selected this source
51- Key findings from this source
52- Any limitations or concerns about the source
53 
54## Summary Report Requirements
55 
56The summary should include:
57- Key concepts and definitions
58- Best practices and techniques (including the "lost in the middle" problem and its solutions)
59- Practical recommendations for agent developers
60- References to sources consulted (use actual URLs from your research)
61- Note the publication date or last updated date for any model context window information; if using older data, explicitly note this limitation
62 
63## Quality Standards
64- Be transparent about uncertainty or gaps in your research
65- Cross-reference key claims across multiple sources when possible
66- Distinguish between established best practices and emerging techniques
67- If you cannot find information on a specific topic, note this explicitly rather than omitting it
