What it does
Migration Report is an agent skill from OpenHands/extensions. Generate a comprehensive migration report summarizing quality scores and providing recommendations. Use after scoring a migration project.
Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Requires migrationscore.json and stylescore.json files
It sits in Data & Analytics. The repository describes itself as: Public registry for OpenHands extensions. The licence is MIT.
When your agent uses it
- Data & Analytics work in your project
Example prompts
- “/migration-report”
Requirements
- Compatibility (from SKILL.md): Requires migration_score.json and style_score.json files
Workflow steps
6 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit d008b81. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Requires migration_score.json and style_score.json files
From compatibility in the SKILL.md frontmatter.
Context cost
Migration Report loads about 768 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 270 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Generate a comprehensive migration report that summarizes scores and provides actionable insights.
Prerequisites: Migration quality scores and style scores must exist (see migration-score-quality and migration-score-style skills).
Report Structure
1. Executive Summary
- Overall migration health (High/Medium/Low confidence)
- Key statistics: total files, average scores, score distribution
- One-paragraph assessment for stakeholders
2. Score Overview
Coverage Statistics
- Average coverage score
- Files with coverage < 3 (needs attention)
- Files with coverage = 5 (complete)
Correctness Statistics
- Average correctness score
- Files with correctness < 3 (needs attention)
- Files with correctness = 5 (verified)
Style Statistics
- Average style score per attribute
- Common style issues identified
3. Risk Assessment
Categorize files into:
- Green: Coverage ≥ 4, Correctness ≥ 4, Style ≥ 4
- Yellow: Any score between 3-4
- Red: Any score < 3
4. Notable Findings
Strengths
- What was migrated well
- Good patterns to replicate
Weaknesses
- Common issues across files
- Patterns to avoid
5. Recommendations
Prioritized action items:
- Critical — Files with scores < 3
- Important — Files with scores 3-4
- Nice to have — Style improvements for green files
6. Detailed Scores
Include the raw scores for reference (or link to score files).
Output Format
Generate the report as a Markdown file:
# Migration Quality Report
**Generated**: 2024-01-15
**Project**: Customer Management System
**Source**: COBOL (45 files)
**Target**: Java (62 files)
## Executive Summary
Migration is at **MEDIUM confidence** with average coverage of 4.2/5 and
correctness of 4.0/5. Three files require immediate attention due to
incomplete business logic migration.
## Score Overview
### Coverage
- Average: 4.2/5
- Complete (5): 28 files (62%)
- Needs attention (<3): 3 files (7%)
...Tone and Audience
- Write for technical stakeholders (architects, tech leads)
- Be specific about issues (cite file names, line numbers if relevant)
- Provide actionable recommendations, not vague suggestions
- Acknowledge good work, not just problems
Data Sources
Read scores from:
migration_score.json— Coverage and correctness scoresstyle_score.json— Style evaluation scoresmigration_mapping.json— File mapping (for counts)
Example Recommendations
Good:
"CALC001.java has coverage 2/5 because batch processing logic in CALC001.cbl lines 150-200 was not migrated. Implement the
processBatch()method to match COBOL paragraph PROCESS-BATCH."
Bad:
"Some files need more work."
