description: >
  From T-174 GO decision. With auto-compaction disabled, pre-compact.sh and the SessionStart:compact
  hook fire only on manual /compact. Tasks: (1) Add comment to pre-compact.sh noting
  it's manual-only now. (2) Review .claude/settings.json PreCompact and SessionStart:compact
  hooks — simplify or document. (3) Consider if detect_compaction() in checkpoint.sh
  is dead code. (4) Update compact-log format to distinguish manual vs auto (for diagnostics).
  (5) Document in CLAUDE.md that /compact is available for manual use but auto-compaction
  is disabled by design.

# T-177: Clean up compact hooks for manual-only use

## Context

With auto-compaction disabled (D-027), pre-compact.sh and SessionStart:compact hooks only fire on manual `/compact`. Clean up comments, compact-log format, and document manual-only behavior.

## Acceptance Criteria

- [x] pre-compact.sh header updated to note manual-only trigger
- [x] compact-log entries tagged [manual] for diagnostics
- [x] detect_compaction() in checkpoint.sh annotated (still useful, not dead code)
- [x] CLAUDE.md documents that /compact is available for manual use

## Verification

grep -q "manual /compact" /opt/999-Agentic-Engineering-Framework/agents/context/pre-compact.sh
grep -q "manual" /opt/999-Agentic-Engineering-Framework/agents/context/checkpoint.sh
grep -q "/compact" /opt/999-Agentic-Engineering-Framework/CLAUDE.md
