compact

Commands for shrinking the database records of old closed issues by replacing their full content with summaries. An issue is a tracked task, bug, or piece of work.

In plain words
What is it for?
Previewing eligible issues, compacting all or selected issues, choosing a compression tier, using parallel workers, and viewing storage statistics.
Why use it?
It reduces storage use in long-running projects, but the original content is discarded from the database and must be recovered from Git history if needed.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 8 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 276 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin 92% copy Near-identical to another mod in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

compact scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

92% identical to compact — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Reduce database size by summarizing closed issues no longer actively referenced.

Compaction Tiers

  • Tier 1: Semantic compression (30+ days closed, ~70% size reduction)
  • Tier 2: Ultra compression (90+ days closed, ~95% size reduction)

Usage

  • Preview candidates: bd admin compact --dry-run
  • Compact all eligible: bd admin compact --all
  • Compact specific issue: bd admin compact --id bd-42
  • Force compact: bd admin compact --id bd-42 --force (bypass age checks)
  • View statistics: bd admin compact --stats

Options

  • --tier: Choose compaction tier (1 or 2, default: 1)
  • --workers: Parallel workers (default: 5)
  • --batch-size: Issues per batch (default: 10)

Important

This is permanent graceful decay - original content is discarded. Use bd restore <id> to view full history from git if needed.

Useful for long-running projects to keep database size manageable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
