/resume-session

description: Load the most recent session file from ~/.claude/session-data/ and resume work with full context from where the last session ended.

Resume Session Command

Load the last saved session state and orient fully before doing any work. This command is the counterpart to `/save-session`.

When to Use

• Starting a new session to continue work from a previous day
• After starting a fresh session due to context limits
• When handing off a session file from another source (just provide the file path)
• Any time you have a session file and want Claude to fully absorb it before proceeding

Usage

/resume-session                                                      # loads most recent file in ~/.claude/session-data/
/resume-session 2024-01-15                                           # loads most recent session for that date
/resume-session ~/.claude/session-data/2024-01-15-abc123de-session.tmp  # loads a current short-id session file
/resume-session ~/.claude/sessions/2024-01-15-session.tmp               # loads a specific legacy-format file

Process

Step 1: Find the session file

If no argument provided:

1. Check `~/.claude/session-data/` 2. Read the matching `*-session.tmp` candidates and apply the candidate ranking below 3. Load the highest-ranked candidate 4. If the folder does not exist or has no eligible matching files, tell the user:

   No session files found in ~/.claude/session-data/
   Run /save-session at the end of a session to create one.

Then stop.

If an argument is provided:

• If it looks like a date (`YYYY-MM-DD`), search `~/.claude/session-data/` first, then the legacy

`~/.claude/sessions/`, for files matching `YYYY-MM-DD-session.tmp` (legacy format) or `YYYY-MM-DD-<shortid>-session.tmp` (current format), apply the candidate ranking below across all matches, and load the highest-ranked candidate for that date

• If it looks like a file path, read exactly that file directly. Do not apply candidate ranking or

substitute a different file, even if the requested file is empty or another file is newer

• If not found, report clearly and stop

Candidate ranking for implicit and date-based lookup

Rank only automatically discovered candidates. Never use this ranking for an explicit file path.

1. Reject files that are unreadable, empty, whitespace-only, or contain only headings, metadata, separators, and placeholder values such as `[Session context goes here]`, `- [ ]`, a lone `-`, or `[relevant files]`. 2. Reject generated summaries with only one task and no populated files-modified, tools-used, completed, in-progress, notes, or context-to-load content. This structural rule filters one-message summarizer echoes without depending on any particular prompt text. 3. Keep candidates with substantive populated content: completed work, in-progress work, concrete next-session notes, concrete context paths, multiple tasks, modified files, or tools used. 4. Among eligible substantive candidates, prefer the newest modification time. 5. If modification times are equal, prefer more populated sections, then more non-placeholder content, then larger byte size, then the lexicographically smaller resolved path. Count populated sections and content only after removing headings, metadata, separators, and placeholder text. These final tie-breaks make selection deterministic.

Step 2: Read the entire session file

Read the complete file. Do not summarize yet.

Step 3: Confirm understanding

Respond with a structured briefing in this exact format:

SESSION LOADED: [actual resolved path to the file]
════════════════════════════════════════════════

PROJECT: [project name / topic from file]

WHAT WE'RE BUILDING:
[2-3 sentence summary in your own words]

CURRENT STATE:
PASS: Working: [count] items confirmed
 In Progress: [list files that are in progress]
 Not Started: [list planned but untouched]

WHAT NOT TO RETRY:
[list every failed approach with its reason — this is critical]

OPEN QUESTIONS / BLOCKERS:
[list any blockers or unanswered questions]

NEXT STEP:
[exact next step if defined in the file]
[if not defined: "No next step defined — recommend reviewing 'What Has NOT Been Tried Yet' together before starting"]

════════════════════════════════════════════════
Ready to continue. What would you like to do?

Step 4: Wait for the user

Do NOT start working automatically. Do NOT touch any files. Wait for the user to say what to do next.

If the next step is clearly defined in the session file and the user says "continue" or "yes" or similar — proceed with that exact next step.

If no next step is defined — ask the user where to start, and optionally suggest an approach from the "What Has NOT Been Tried Yet" section.

Edge Cases

**Multiple sessions for the same date** (`2024-01-15-session.tmp`, `2024-01-15-abc123de-session.tmp`): Apply the candidate ranking across every matching legacy and current-format file. A substantive session must win over a newer placeholder or one-message summarizer echo; modification time decides between eligible candidates.

**Session file references files that no longer exist:** Note this during the briefing — "WARNING: `path/to/file.ts` referenced in session but not found on disk."

**Session file is from more than 7 days ago:** Note the gap — "WARNING: This session is from N days ago (threshold: 7 days). Things may have changed." — then proceed normally.

**User provides a file path directly (e.g., forwarded from a teammate):** Read it and follow the same briefing process — the format is the same regardless of source.

**Session file is empty or malformed:** For implicit or date-based discovery, reject it and continue ranking the remaining candidates. If no eligible candidate remains, report: "Session files were found but appear empty or unreadable. You may need to create a new one with /save-session." For an explicit path, report that the requested file i
