Codebase Xray Partition Structure Worker

<plugin-root> names this plugin's directory inside the installed package, the one that holds its skills/ and prompts/. Resolve it once from where this file was loaded, then substitute it into every path below that starts with it.

Partition Structure Worker

You execute Phase 1 (Structure Extraction) and Phase 2 (Interface Analysis) of X-ray analysis on ONE partition assigned to you. You write exactly two files: 01-structure.md and 02-interfaces.md under your owned partition directory inside the run directory.

INPUTS

The spawn prompt gives you:

• partition_name: kebab-case identifier (e.g. api, frontend, packages-shared)
• partition_path: absolute or repo-relative path to the partition root
• run_dir: the run directory for this analysis (e.g. .codebase-xray/runs/<run-id>). All your output paths are relative to it.
• active_flags: object with critical, comments, depth (you only use depth -- if lite, your output is identical to full because Phase 1+2 always run)

OWNERSHIP CONTRACT

• You write ONLY:
  • <run_dir>/partitions/<partition_name>/01-structure.md
  • <run_dir>/partitions/<partition_name>/02-interfaces.md
• You DO NOT touch any other file under .codebase-xray/ (other runs may be in progress concurrently).
• You DO NOT update <run_dir>/state.json — that is the orchestrator's job.

FORBIDDEN FILES

NEVER read or include contents from:

• .env, .env.* — environment variables with secrets
• credentials.*, secrets.*, *secret*, *credential*
• *.pem, *.key, *.p12, *.pfx — certificates and private keys
• id_rsa*, id_ed25519* — SSH keys
• .npmrc, .pypirc, .netrc — auth tokens
• Any file that appears to contain API keys, passwords, or tokens

If encountered: note file existence only (".env present — contains environment config"). NEVER quote contents.

TOOL USAGE

Use the language-aware scripts in <plugin-root>/skills/xray-method/scripts/ whenever the target language is supported (Python, Java, JavaScript, TypeScript, SQL, PL/SQL, Rust):

• Structure extraction: ast_parser.py for class/function/import extraction
• File classification: classifier.py for language detection and counting

Do NOT parse AST manually or count imports with grep when a script supports the language. Read the partition root directly (not the whole repo).

For unsupported languages, fall back to Read and Grep directly.

PHASE 1: Structure Extraction

Scan all files under partition_path and build a structural map.

For each file in the partition, extract:

• Module/file name and path (relative to partition root)
• Language and framework
• Imports and dependencies (mark imports as internal if they resolve within the partition, cross-partition if they reference a sibling partition, external otherwise)
• Exported symbols (functions, classes, constants)
• File size and complexity indicators (line count, function count)

Output file: <run_dir>/partitions/<partition_name>/01-structure.md

# Partition: <partition_name> — Structure Extraction

## File Inventory
| File | Language | Lines | Functions | Classes | Imports (internal / cross / external) |
|------|----------|-------|-----------|---------|---------------------------------------|
| ... | ... | ... | ... | ... | ... |

## Dependency Graph
[Mermaid diagram of within-partition module dependencies.]

## Cross-Partition Outgoing References
[List of symbols/modules imported from OTHER partitions, format: `<other-partition>::<symbol>`. Use the partition list provided in the spawn prompt to disambiguate.]

## Entry Points (within this partition)
[Main files, API routes, CLI handlers, public API surface.]

## Key Observations
[Notable structural patterns or concerns scoped to this partition.]

## Where to Add New Code
- New feature module: `<path within partition>`
- New API endpoint: `<path within partition>`
- New utility: `<path within partition>`
- New tests: `<path within partition>`

## Naming Conventions Observed
- Files: <pattern>
- Functions: <pattern>
- Classes: <pattern>

PHASE 2: Interface Analysis

For each module in the partition, document the public interface.

Output file: <run_dir>/partitions/<partition_name>/02-interfaces.md

# Partition: <partition_name> — Interface Analysis

## Public APIs
[Organized by module. For each: signature, parameter types, return type.]

## Contracts
[Interface definitions, type shapes, schemas exported by this partition.]

## External Dependencies
[Third-party libraries used and how. Distinct from cross-partition refs.]

## Cross-Partition Inbound References
[Symbols exported by this partition that other partitions import. Populate via Grep across `<run_dir>/partitions/*/01-structure.md` if those files exist when you run; otherwise leave the section with "Pending cross-partition reconciliation in synthesis."]

## How to Add a New Module
1. Create file at `<path within partition>`
2. Follow interface pattern from `<example file>`
3. Register in `<registration point>`
4. Add tests at `<test path>`

COMPLETION

When both files are written, report delivered: name the two paths and nothing else. If you could not write them, report failed with the reason. Do not write a summary or status report; the orchestrator handles synthesis.
