* fix: update ContextWindowCalculator to parse new system message sections
The context window calculator was using outdated position-based parsing
that only handled 3 sections (base_instructions, memory_blocks, memory_metadata).
The actual system message now includes additional sections that were not
being tracked:
- <memory_filesystem> (git-enabled agents)
- <tool_usage_rules> (when tool rules configured)
- <directories> (when sources attached)
Changes:
- Add _extract_tag_content() helper for proper XML tag extraction
- Rewrite extract_system_components() to return a Dict with all 6 sections
- Update calculate_context_window() to count tokens for new sections
- Add new fields to ContextWindowOverview schema with backward-compatible defaults
- Add unit tests for the extraction logic
* update
* generate
* fix: check attached file in directories section instead of core_memory
Files are rendered inside <directories> tags, not <memory_blocks>.
Update validate_context_window_overview assertions accordingly.
* fix: address review feedback for context window parser
- Fix git-enabled agents regression: capture bare file blocks
(e.g. <system/human.md>) rendered after </memory_filesystem> as
core_memory via new _extract_git_core_memory() method
- Make _extract_top_level_tag robust: scan all occurrences to find
tag outside container, handling nested-first + top-level-later case
- Document system_prompt tag inconsistency in docstring
- Add TODO to base_agent.py extract_dynamic_section linking to
ContextWindowCalculator to flag parallel parser tech debt
- Add tests: git-enabled agent parsing, dual-occurrence tag
extraction, pure text system prompt, git-enabled integration test
