Reconstructs session logs from Claude Code transcripts when a session crashes or is closed before /save. Two entry points: - /recover <uuid|latest> : manual, Claude-reviewed reconstruction - detect_orphaned_sessions.py : scheduled scan that auto-builds logs for substantive, unsaved, not-yet-recovered transcripts (banner-marked RECOVERED-UNVERIFIED), commits them, and posts a #bot-alerts FYI. recover_session.py is the shared engine: Python extracts the verbatim command/config/reference timeline; Ollama drafts prose-only narrative. Machine-local ledger (.claude/state/) prevents reprocessing. Reviewed: git add scoped to own files, ledger written only after successful push, per-uuid idempotency, --max cap for unattended runs.

Reconstruct a session log from a Claude Code transcript when a session crashed or was closed before /save.
Claude Code writes every session live to a transcript JSONL under ~/.claude/projects/<slug>/<uuid>.jsonl. /recover distills one of those transcripts back into a normal session log in the .claude/commands/save.md format. This is the manual, reviewed path; the background detector (detect_orphaned_sessions.py) handles unattended auto-recovery.
Usage
| Invocation | Action |
|---|---|
/recover <uuid> |
Reconstruct the session with that transcript uuid |
/recover latest |
Reconstruct the newest transcript by mtime |
/recover --list |
Show candidate orphans (runs the detector --dry-run) |
Flow: /recover --list
Run the detector in scan-only mode and present the table to the user:
py .claude/scripts/detect_orphaned_sessions.py --dry-run
The table shows every past-idle, not-yet-processed transcript with its uuid, mtime, substantive/saved/orphan verdicts, classified scope, and the path a recovery would write to. Point the user at the rows where orphan is YES — those are unsaved substantive sessions. Nothing is written.
Flow: /recover <uuid> or /recover latest
This is a reviewed recovery. Claude is the editor, not a passive writer.
-
Generate the draft (prints to stdout, writes nothing):
py .claude/scripts/recover_session.py --uuid <uuid> --print(or
--latest). The draft contains:- Ollama-drafted prose: Session Summary, Key Decisions, Problems Encountered, Pending / Incomplete Tasks.
- Python-extracted verbatim evidence: Configuration Changes, Commands & Outputs, Reference Information, Infrastructure & Servers, Credentials & Secrets.
- A
[RECOVERED -- UNVERIFIED]banner and the canonical User block (fromwhoami-block.sh).
-
Review the draft. This is the point of the manual path:
- Verify the Commands / Config / Reference appendix matches what actually happened and what the user intended. These are machine-extracted verbatim — confirm they are complete and not misleading.
- Correct the scope and slug: the classifier is conservative and may land on
general(or the wrong project/client) when work spanned several areas. Fix the targetsession-logs/directory accordingly. - Tighten the topic in the filename and the title.
- Correct or rewrite the Ollama prose where it is imprecise. If Ollama was unreachable, write the prose sections yourself from the verbatim evidence.
-
Write the final log. Once verified, write the corrected markdown to the correct
session-logs/path (client ->clients/<slug>/session-logs/, project ->projects/<project>/session-logs/, general -> rootsession-logs/), using the transcript's first-timestamp date:YYYY-MM-DD-recovered-<topic>.md. Drop the UNVERIFIED banner — by writing it yourself you have verified it. -
Sync:
bash .claude/scripts/sync.sh -
Unseeded wiki check. If the scope is a client or project with no
wiki/<type>/<slug>.mdarticle yet, suggest:[INFO] No wiki article for '<slug>' yet. Run /wiki-compile <type>:<slug> to seed it.
Difference from the automatic detector
/recover (this command) |
detect_orphaned_sessions.py (background) |
|
|---|---|---|
| Trigger | Manual, on demand | Scheduled task (every few hours + at logon) |
| Review | Claude reviews and corrects before writing | None — auto-writes unreviewed |
| Banner | Removed once verified | Kept ([RECOVERED -- UNVERIFIED]) until a human reviews |
| Scope/topic | Corrected by Claude | Whatever the classifier decided |
| Output | Final, clean session log | Banner-marked draft committed for later review |
Use /recover when you know a specific session was lost and want a clean log. Let the detector catch the ones you forget.
Notes
--autoand--jsonmodes onrecover_session.pyexist for the detector and for scripting;/recoveruses--printso Claude always reviews before anything lands on disk.- The prose is Ollama-drafted from the transcript; the Commands/Config/Reference sections are extracted verbatim by Python. Never trust the prose for exact commands, IPs, credentials, paths, SHAs, or ticket IDs — read those from the verbatim sections.
- Transcripts are per-machine. You can only recover sessions that ran on the machine you are on.
