Compact Conversation Logs

Remove detritus from conversation logs while archiving removed content for reference. Works with both Claude Code and OpenCode conversation histories.

Arguments

• project (default): Compact current project's conversations only
• all: Compact all projects globally (both tools)
• {project-name}: Compact specific project by name

Process

1. Detect Tool & Locate Conversations

IMPORTANT: First detect which conversation sources exist:

Claude Code:

• Project: ~/.claude/projects/{hash}/conversations/*.jsonl
• Global: ~/.claude/projects/*/conversations/*.jsonl

OpenCode:

• Sessions: ~/.local/share/opencode/storage/session/ses_*
• Messages: ~/.local/share/opencode/storage/message/ses_*
• Parts: ~/.local/share/opencode/storage/part/msg_*/prt_*.json

2. Use detritus-detector Agent

Launch the detritus-detector agent to identify noise:

• Failed tool loops (3+ retries)
• Greeting/acknowledgment exchanges
• Abandoned threads
• Duplicate error messages
• Clarification spirals

3. Show What Will Be Archived

Present summary before archiving:

Detritus Found
══════════════════════════════════
Source: Claude Code
├── Conversation abc123:
│   ├── [lines 45-67] Failed grep loop (5 attempts)
│   └── [lines 120-125] Greeting exchange

Source: OpenCode
├── Session ses_485d888e:
│   ├── [msg_19b370...] Failed tool loop (4 attempts)
│   └── [msg_19b371...] "Let me try again" x3

Total: 156 segments across 8 conversations/sessions
Archive location: ~/.claude/insights/archive/2026-01-01/

4. Archive Detritus

Move flagged content to archive:

• Create ~/.claude/insights/archive/YYYY-MM-DD/
• Save each conversation's detritus with context
• Include source (Claude Code/OpenCode), IDs, and timestamps

5. Update Original Logs

Claude Code: Remove detritus from JSONL files:

• Replace with compact marker: {"archived": true, "lines": 23, "reason": "failed tool loop"}

OpenCode: Mark parts as archived (don't delete - OpenCode manages its own storage):

• Create archive reference file listing archived message IDs
• Note: OpenCode storage is managed internally, so we archive copies rather than modify

6. Report Results

Compaction Complete
══════════════════════════════════
Sources processed:
  - Claude Code: 8 conversations
  - OpenCode: 12 sessions
Segments archived: 156
Space saved: ~45KB (Claude Code only - OpenCode archived separately)
Archive: ~/.claude/insights/archive/2026-01-01/

Original Claude Code logs updated with archive markers.
OpenCode archive references created.

Archive Format

Archived content preserves context and source:

# Archive: Claude Code - abc123
Date: 2026-01-01
Source: Claude Code
Reason: Failed tool loop

## Original Location: lines 45-67

[user]: Search for the config file
[assistant]: Let me search...
[tool_call]: grep "config" - FAILED
[assistant]: Let me try again...
...

---

# Archive: OpenCode - ses_485d888e
Date: 2026-01-01
Source: OpenCode
Reason: Failed tool loop

## Message IDs: msg_19b370..., msg_19b371...

[user]: Find the auth implementation
[assistant]: Searching...
[tool_call]: grep "auth" - FAILED
...

Tips

• Run after /analyze to clean flagged detritus
• Archives are kept indefinitely for reference if needed
• Use all monthly to keep both tools' logs manageable
• OpenCode storage is reference-archived (copies), Claude Code is modified in-place
• Review archives occasionally for false positives
