Lossless Context Commands

You have access to a persistent, DAG-based conversation vault. Every message from every session is preserved in SQLite. Summaries form a directed acyclic graph — nothing is ever deleted.

Available Commands

lcc_grep <query> — Search everything

Full-text search across all messages and summaries in the vault.

lcc_grep "database migration"
lcc_grep "error in auth"

lcc_expand <summary_id> — Drill into a summary

Expand a summary node back to its source messages or child summaries. Use --full for untruncated output.

lcc_expand sum_abc123def456
lcc_expand sum_abc123def456 --full

lcc_context [query] — Get relevant context

Surface the top N most relevant DAG nodes for a query. Without a query, returns highest-depth summaries (broadest overview).

lcc_context "auth refactor"
lcc_context --limit 10

lcc_sessions — List sessions

List recorded sessions with timestamps, working directories, and whether a handoff exists.

lcc_sessions
lcc_sessions --limit 5

lcc_handoff — Session handoff

Show the handoff from a previous session, or generate one for the current session.

lcc_handoff
lcc_handoff --generate --session "$CLAUDE_SESSION_ID"

lcc_status — Vault stats

Show message count, summary count, max depth, vault size.

lcc_status

When to Use

• Starting a new session: Run lcc_context to see what happened recently.
• Picking up where you left off: Run lcc_handoff to see the previous session's summary.
• Searching for past decisions: Run lcc_grep "decision about X".
• Understanding a summary: Run lcc_expand to drill down to the original messages.
• Before ending a session: Run lcc_handoff --generate to save a handoff for next time.

How It Works

Messages are automatically captured by hooks on every turn. Before context compaction, unsummarised messages are chunked and summarised into DAG nodes. Summaries cascade to higher depths when they accumulate. The full chain from high-level overview → detailed summary → original message is always traversable via lcc_expand.
