Background and Context

The v3.6.0 milestone requires advanced context strategies beyond the basic ACMS pipeline. Semantic chunking splits files into semantically meaningful chunks (functions, classes, sections) rather than fixed-size blocks. This enables more precise context selection by including only the relevant portions of files rather than entire files.

Current Behavior

Context selection is file-level only. Entire files are included or excluded. No semantic understanding of file structure is used for context selection.

Expected Behavior

Semantic chunking splits files into meaningful units (functions, classes, methods, sections). Context selection can include individual chunks rather than entire files. Chunk relevance scoring determines which chunks are included within the budget.

Acceptance Criteria

  • Semantic chunking splits Python files into functions/classes/methods
  • Semantic chunking splits Markdown files into sections
  • Context selection can include individual chunks
  • Chunk relevance scoring determines inclusion within budget
  • Semantic chunking is configurable via context policy
  • Test coverage >= 97% for semantic chunking module

Metadata

  • Commit Message: feat: implement semantic chunking context strategy for ACMS
  • Branch Name: feat/acms-semantic-chunking-context-strategy

Subtasks

  • Implement Python AST-based chunking (functions, classes, methods)
  • Implement Markdown section-based chunking
  • Implement chunk relevance scoring
  • Integrate semantic chunking into context assembly pipeline
  • Add semantic chunking configuration to context policy schema
  • Write unit tests for chunking logic
  • Write integration tests for semantic chunking in context assembly

Definition of Done

Semantic chunking splits files into meaningful units, chunk relevance scoring works, and test coverage >= 97%.

Verified — Semantic chunking is an advanced context strategy that extends ACMS beyond the core pipeline. Per the v3.6.0 milestone description, this is 'Advanced context strategies (beyond basic ACMS pipeline)' — explicitly scoped as advanced/deferred. Downgrading to Should Have — important but not blocking core functionality. Verified.
