# Issue Compaction - Quick Reference
|
||||
|
||||
**Status:** Design Complete, Ready for Implementation
|
||||
**Target:** Beads v1.1
|
||||
**Estimated Effort:** 40-60 hours (MVP)
|
||||
|
||||
## What Is This?
|
||||
|
||||
Add intelligent database compaction to beads using Claude Haiku to semantically compress old, closed issues. Keep your database lightweight while preserving the meaning of past work.
|
||||
|
||||
## Why?
|
||||
|
||||
- **Agent Efficiency:** Smaller DBs → faster queries → clearer thinking
|
||||
- **Context Management:** Agents need summaries, not verbose details
|
||||
- **Pragmatic:** Most work is throwaway; forensic value decays exponentially
|
||||
- **Git-Friendly:** Smaller JSONL exports
|
||||
|
||||
## How It Works
|
||||
|
||||
### Two-Tier Compression
|
||||
|
||||
**Tier 1: Standard (30 days)**
|
||||
- Closed ≥30 days, all dependents closed (2 levels deep)
|
||||
- Haiku summarizes to ~300 words
|
||||
- Keeps: title, summary with key decisions
|
||||
- Clears: verbose design/notes/criteria
|
||||
- **Result:** 70-85% space reduction
|
||||
|
||||
**Tier 2: Aggressive (90 days)**
|
||||
- Already Tier 1 compressed
|
||||
- Closed ≥90 days, deep dependencies closed (5 levels)
|
||||
- ≥100 git commits since closure (measures "project time")
|
||||
- Ultra-compress to single ≤150 word paragraph
|
||||
- Optionally prunes old events
|
||||
- **Result:** 90-95% space reduction
|
||||
|
||||
### Safety First
|
||||
|
||||
- **Snapshots:** Full original content saved before compaction
|
||||
- **Restore:** `bd compact --restore <id>` undoes compaction
|
||||
- **Dry-Run:** `bd compact --dry-run` previews without changing anything
|
||||
- **Git Backup:** JSONL commits preserve full history
|
||||
- **Opt-In:** Disabled by default (`auto_compact_enabled = false`)
|
||||
|
||||
## CLI
|
||||
|
||||
```bash
|
||||
# Preview candidates
|
||||
bd compact --dry-run
|
||||
|
||||
# Compact Tier 1
|
||||
bd compact --all
|
||||
|
||||
# Compact Tier 2
|
||||
bd compact --tier 2 --all
|
||||
|
||||
# Compact specific issue
|
||||
bd compact --id bd-42
|
||||
|
||||
# Restore compacted issue
|
||||
bd compact --restore bd-42
|
||||
|
||||
# Show statistics
|
||||
bd compact --stats
|
||||
```
|
||||
|
||||
## Cost
|
||||
|
||||
**Haiku Pricing:**
|
||||
- ~$0.0008 per issue (Tier 1)
|
||||
- ~$0.0003 per issue (Tier 2)
|
||||
- **~$1.10 per 1,000 issues total**
|
||||
|
||||
Negligible for typical usage (~$0.05/month for active project).
|
||||
|
||||
## Example Output
|
||||
|
||||
### Before Compaction
|
||||
```
|
||||
bd-42: Fix authentication bug [CLOSED]
|
||||
|
||||
Description: (800 words about the problem)
|
||||
|
||||
Design: (1,200 words of implementation notes)
|
||||
|
||||
Notes: (500 words of testing/deployment details)
|
||||
|
||||
Acceptance Criteria: (300 words of requirements)
|
||||
|
||||
Total: 2,341 bytes
|
||||
```
|
||||
|
||||
### After Tier 1 Compaction
|
||||
```
|
||||
bd-42: Fix authentication bug [CLOSED] 🗜️
|
||||
|
||||
**Summary:** Fixed race condition in JWT token refresh logic causing
|
||||
intermittent 401 errors. Implemented mutex-based locking. All users
|
||||
can now stay authenticated reliably.
|
||||
|
||||
**Key Decisions:**
|
||||
- Used sync.RWMutex for simpler reasoning
|
||||
- Added exponential backoff to prevent thundering herd
|
||||
- Preserved token format for backward compatibility
|
||||
|
||||
**Resolution:** Deployed Aug 31, zero 401s after 2 weeks monitoring.

## Haiku Prompts
|
||||
|
||||
### Tier 1 (300 words)
|
||||
```
|
||||

|
||||
|
||||
Title: {{.Title}}
|
||||
Type: {{.IssueType}}
|
||||
Priority: {{.Priority}}
|
||||
|
||||
Description: {{.Description}}
|
||||
Design Notes: {{.Design}}
|
||||

||||
**Summary:** [2-3 sentences: problem, solution, outcome]
|
||||
**Key Decisions:** [bullet points of non-obvious choices]
|
||||
**Resolution:** [how it was closed]
|
||||
```
|
||||
|
||||
### Tier 2 (150 words)
|
||||
```
|
||||
Ultra-compress this old closed issue to ≤150 words.
|
||||
Focus on lasting architectural impact.
|
||||
|
||||
Title: {{.Title}}
|
||||
Original Summary: {{.Description}}
|
||||
|
||||
Output a single paragraph covering:
|
||||
- What was built/fixed
|
||||
- Why it mattered
|
||||
- Lasting impact (if any)
|
||||
```
|
||||
|
||||
## Success Metrics
|
||||
|
||||
- **Space:** 70-85% reduction (Tier 1), 90-95% (Tier 2)
|
||||
- **Quality:** Summaries preserve essential context
|
||||
- **Safety:** 100% restore success rate
|
||||
- **Performance:** <100ms candidate query, ~2s per issue (Haiku)
|
||||
- **Cost:** <$1.50 per 1,000 issues
|
||||
|
||||
## Risks & Mitigations
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Info loss in summaries | Dry-run review, restore capability, prompt tuning |
|
||||
| API rate limits | Exponential backoff, respect limits, batch sizing |
|
||||
| Accidental compression | Dry-run required, snapshots permanent |
|
||||
| JSONL conflicts | Compaction is deterministic, git handles well |
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Review design:** `COMPACTION_DESIGN.md` (comprehensive spec)
|
||||
2. **File issues:** `bd create -f compaction-issues.md` (16 issues)
|
||||
3. **Start implementation:** Begin with schema + config (Issues 1-2)
|
||||
4. **Iterate:** Build MVP (Tier 1 only), then enhance
|
||||

### Description
|
||||
|
||||
Add database schema support for issue compaction tracking and snapshot storage.
|
||||
|
||||
### Design
|
||||
|
||||
Add three columns to `issues` table:
|
||||
- `compaction_level INTEGER DEFAULT 0` - 0=original, 1=tier1, 2=tier2
|
||||
- `compacted_at DATETIME` - when last compacted
|
||||
- `original_size INTEGER` - bytes before first compaction
|
||||
|
||||
Create `issue_snapshots` table:
|
||||
```sql
|
||||
CREATE TABLE issue_snapshots (
|
||||
id INTEGER PRIMARY KEY AUTOINCREMENT,
|
||||
issue_id TEXT NOT NULL,
|
||||
snapshot_time DATETIME NOT NULL,
|
||||
compaction_level INTEGER NOT NULL,
|
||||
original_size INTEGER NOT NULL,
|
||||
compressed_size INTEGER NOT NULL,
|
||||
original_content TEXT NOT NULL, -- JSON blob
|
||||
archived_events TEXT,
|
||||
FOREIGN KEY (issue_id) REFERENCES issues(id) ON DELETE CASCADE
|
||||
);
|
||||
```
|
||||
|
||||
Add indexes:
|
||||
- `idx_snapshots_issue` on `issue_id`
|
||||
- `idx_snapshots_level` on `compaction_level`
|
||||
|
||||
Add migration functions in `internal/storage/sqlite/sqlite.go`:
|
||||
- `migrateCompactionColumns(db *sql.DB) error`
|
||||
- `migrateSnapshotsTable(db *sql.DB) error`
|
||||
|
||||
### Acceptance Criteria
|
||||
- Existing databases migrate automatically
|
||||
- New databases include columns by default
|
||||
- Migration is idempotent (safe to run multiple times)
|
||||
- No data loss during migration
|
||||
- Tests verify migration on fresh and existing DBs

('compact_batch_size', '50'),
|
||||
('compact_parallel_workers', '5'),
|
||||
('auto_compact_enabled', 'false');
|
||||
```
|
||||
|
||||
Add helper functions for loading config into typed struct.
|
||||
|
||||
### Acceptance Criteria
|
||||
- Config keys created on init
|

||||
Implement snapshot creation before compaction and restoration capability to undo compaction.
|
||||
|
||||
### Design
|
||||
|
||||
Add to `internal/storage/sqlite/compact.go`:
|
||||
|
||||
```go

|
||||
|
||||
### Description
|
||||
|
||||
Implement the core Tier 1 compaction process: snapshot → summarize → update.
|
||||
|
||||
### Design
|
||||
|
||||
Add to `internal/compact/compactor.go`:
|
||||
|
||||
```go
|
||||
type Compactor struct {
|
||||
store storage.Storage
|
||||
haiku *HaikuClient
|
||||
config *CompactConfig
|
||||
}
|
||||
|
||||
func New(store storage.Storage, apiKey string, config *CompactConfig) (*Compactor, error)
|
||||
func (c *Compactor) CompactTier1(ctx context.Context, issueID string) error
|
||||
func (c *Compactor) CompactTier1Batch(ctx context.Context, issueIDs []string) error
|
||||
```
|
||||
|
||||
Process:
|
||||
1. Verify eligibility
|
||||
2. Calculate original size
|
||||
3. Create snapshot
|
||||
4. Call Haiku for summary
|
||||
5. Update issue (description=summary, clear design/notes/criteria)
|
||||
6. Set compaction_level=1, compacted_at=now, original_size
|
||||
7. Record EventCompacted
|
||||
8. Mark dirty for export
|
||||
|
||||
### Acceptance Criteria
|
||||
- Single issue compaction works end-to-end
|
||||
- Batch processing with parallel workers (5 concurrent)
|
||||
- Errors don't corrupt database (transaction rollback)
|
||||
- EventCompacted includes size savings
|
||||
- Dry-run mode (identify + size estimate only, no API calls)

### Description
|
||||
|
||||
Implement Tier 2 ultra-compression: more aggressive summarization and optional event pruning.
|
||||
|
||||
### Design
|
||||
|
||||
Add to `internal/compact/compactor.go`:
|
||||
|
||||
```go
|
||||
func (c *Compactor) CompactTier2(ctx context.Context, issueID string) error
|
||||
func (c *Compactor) CompactTier2Batch(ctx context.Context, issueIDs []string) error
|
||||
```
|
||||
|
||||
Process:
|
||||
1. Verify issue is at compaction_level = 1
|
||||
2. Check Tier 2 eligibility (days, deps, commits/issues)
|
||||
3. Create Tier 2 snapshot
|
||||
4. Call Haiku with ultra-compression prompt
|
||||
5. Update issue (description = single paragraph, clear all other fields)
|
||||
6. Set compaction_level = 2
|
||||
7. Optionally prune events (keep created/closed, archive rest to snapshot)
|
||||
|
||||
### Acceptance Criteria
|
||||
- Requires existing Tier 1 compaction
|
||||
- Git commit counting works (with fallback to issue counter)
|
||||
- Events optionally pruned (config: compact_events_enabled)
|
||||
- Archived events stored in snapshot JSON
|
||||
- Size reduction 90-95%

||||
Create `cmd/bd/compact.go`:
|
||||
|
||||
```go
|
||||
var compactCmd = &cobra.Command{
|
||||
Use: "compact",
|
||||
Short: "Compact old closed issues to save space",
|
||||
}
|
||||
|
||||
Flags:
|
||||
--dry-run Preview without compacting
|
||||
--tier int Compaction tier (1 or 2, default: 1)
|
||||
--all Process all candidates
|
||||
--id string Compact specific issue
|
||||
--force Force compact (bypass checks, requires --id)
|
||||
--batch-size int Issues per batch
|
||||
--workers int Parallel workers
|
||||
--json JSON output
|
||||
```
|
||||
|
||||
### Acceptance Criteria
|
||||
- `--dry-run` shows accurate preview with size estimates
|
||||
- `--all` processes all candidates
|
||||
- `--id` compacts single issue
|
||||

Implement restore command to undo compaction from snapshots.
|
||||
|
||||
### Design
|
||||
|
||||
Add to `cmd/bd/compact.go`:
|
||||
|
||||
```go
|
||||
var compactRestore string
|
||||
|
||||
compactCmd.Flags().StringVar(&compactRestore, "restore", "", "Restore issue from snapshot")
|
||||
```
|
||||
|
||||
Process:
|
||||
1. Load snapshot for issue
|
||||
2. Parse JSON content
|
||||
3. Update issue with original content
|
||||
4. Set compaction_level = 0, compacted_at = NULL, original_size = NULL
|
||||
5. Record event (EventRestored or EventUpdated)
|
||||
6. Mark dirty for export
|
||||
|
||||
### Acceptance Criteria
|
||||
- Restores exact original content
|
||||
- Handles multiple snapshots (use latest by default)
|
||||
- `--level` flag to choose specific snapshot
|

### Description
|
||||
|
||||
Implement automatic compaction triggered by certain operations when enabled via config.
|
||||
|
||||
### Design
|
||||
|
||||
Trigger points (when `auto_compact_enabled = true`):
|
||||
1. `bd stats` - check and compact if candidates exist
|
||||
2. `bd export` - before exporting
|
||||
3. Configurable: on any read operation after N candidates accumulate
|
||||
|
||||
Add:
|
||||
```go
|
||||
func (s *SQLiteStorage) AutoCompact(ctx context.Context) error {
|
||||
enabled, _ := s.GetConfig(ctx, "auto_compact_enabled")
|
||||
if enabled != "true" {
|
||||
return nil
|
||||
}
|
||||
|
||||
// Run Tier 1 compaction on all candidates
|
||||
// Limit to batch_size to avoid long operations
|
||||
// Log activity for transparency
|
||||
}
|
||||
```
|
||||
|
||||
### Acceptance Criteria
|
||||
- Respects auto_compact_enabled config (default: false)
|
||||
- Limits batch size to avoid blocking operations
|
||||
- Logs compaction activity (visible with --verbose)
|
||||
- Can be disabled per-command with `--no-auto-compact` flag
|
||||
- Only compacts Tier 1 (Tier 2 remains manual)
|
||||
- Doesn't run more than once per hour (rate limiting)

### Description
|
||||
|
||||
Implement git commit counting for "project time" measurement as alternative to calendar time for Tier 2 eligibility.
|
||||
|
||||
### Design
|
||||
|
||||
```go
|
||||
func getCommitsSince(closedAt time.Time) (int, error) {
|
||||
cmd := exec.Command("git", "rev-list", "--count",
|
||||
fmt.Sprintf("--since=%s", closedAt.Format(time.RFC3339)), "HEAD")
|
||||
output, err := cmd.Output()
|
||||
if err != nil {
|
||||
return 0, err // Not in git repo or git not available
|
||||
}
|
||||
return strconv.Atoi(strings.TrimSpace(string(output)))
|
||||
}
|
||||
```
|
||||
|
||||
Fallback strategies:
|
||||
1. Git commit count (preferred)
|
||||
2. Issue counter delta (store counter at close time, compare later)
|
||||
3. Pure time-based (90 days)
|
||||
|
||||
### Acceptance Criteria
|
||||
- Counts commits since closed_at timestamp
|
||||
- Handles git not available gracefully (falls back)
|
||||
- Fallback to issue counter delta works
|
||||
- Configurable via compact_tier2_commits config key
|
||||
- Tested with real git repo
|
||||
- Works in non-git environments
