What it does

Session Management is an agent skill from athola/claude-night-market. Manages Claude Code sessions with naming, checkpointing, and resume strategies. Use when organizing long-running work or resuming across sessions.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Authentication and Pull requests. The repository describes itself as: 23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context… The licence is MIT.

When your agent uses it

  • Organizing long-running work
  • Resuming across sessions

Example prompts

  • “Use the session-management skill to manage Claude Code sessions with naming, checkpointing, and resume strategies”
  • “/session-management”

Workflow steps

8 steps, taken from the step headings in SKILL.md.

  1. Debugging Sessions
  2. Feature Development Checkpoints
  3. PR Review Sessions
  4. PR-Linked Sessions (Claude Code 2.1.27+)
  5. Investigation Sessions
  6. Resume Hint on Exit (Claude Code 2.1.31+)
  7. Automatic Memory (Claude Code 2.1.32+)
  8. Agent Persistence on Resume (Claude Code 2.1.32+)

What it can do on your machine

Read from SKILL.md and the folder at commit 9f3eb00. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • claude
    • gh

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Session Management loads about 2k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 817 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Session Management

When To Use

  • Managing session checkpoints and state preservation
  • Resuming work across Claude Code sessions

When NOT To Use

  • Short sessions that do not need checkpoints
  • Fresh starts where no prior session context exists

Overview

Claude Code supports named sessions for better workflow organization. Use this skill to manage complex, long-running work across multiple sessions.

Available Commands

CommandDescription
/renameName the current session (auto-generates name if no argument given, 2.1.41+)
/resumeResume a previous session (REPL)
claude --resume <name>Resume from terminal

Workflow Patterns

1. Debugging Sessions

Name debug sessions for easy resumption:

# Start debugging
/rename debugging-auth-issue

# ... work on the issue ...

# If you need to pause, session is auto-saved
# Resume later:
claude --resume debugging-auth-issue
2. Feature Development Checkpoints

Create checkpoints during long feature work:

# After completing milestone 1
/rename feature-x-milestone-1

# Continue in new session
# Reference old session if needed
3. PR Review Sessions

For complex PR reviews that span multiple sittings:

# Start review
/rename pr-review-123

# Take breaks without losing context
# Resume:
claude --resume pr-review-123
4. PR-Linked Sessions (Claude Code 2.1.27+)

Sessions are automatically linked to PRs when created via gh pr create. Resume PR-specific sessions later:

# Resume session for a specific PR
claude --from-pr 156
claude --from-pr https://github.com/org/repo/pull/156

# Workflow: review → pause → resume with full context
/rename pr-review-156
# ... review work ...
# Later:
claude --from-pr 156
5. Investigation Sessions

When investigating issues that may require research:

# Start investigation
/rename investigate-memory-leak

# Pause to gather more info externally
# Resume with full context:
claude --resume investigate-memory-leak

Resume Screen Features

The /resume screen provides:

  • Grouped forked sessions: See related sessions together
  • Keyboard shortcuts (defaults, customizable via /keybindings):
    • Preview session content
    • Rename a session
  • Recent sessions: Sorted by last activity
6. Resume Hint on Exit (Claude Code 2.1.31+)

Claude Code now shows a resume hint when you exit, displaying the command to continue your conversation. This makes session resumption more discoverable: users no longer need to know about --resume beforehand.

Best Practices

Naming Conventions

Use descriptive, hyphenated names:

PatternExampleUse Case
debugging-<issue>debugging-auth-401Bug investigation
feature-<name>-<milestone>feature-search-v2Feature development
pr-review-<number>pr-review-156PR reviews
investigate-<topic>investigate-perfResearch
refactor-<area>refactor-api-layerRefactoring work
When to Name Sessions

Name sessions when:

  • Work will span multiple days
  • You might need to pause unexpectedly
  • The session contains valuable context
  • You want to reference it later
Session Cleanup

Unnamed sessions are eventually garbage collected. Named sessions persist longer. Periodically clean up old named sessions you no longer need.

Integration with Sanctum

Combine session management with other Sanctum skills:

  1. Before starting: Run Skill(sanctum:git-workspace-review) to capture context
  2. Name the session: /rename <descriptive-name>
  3. Work: Use appropriate skills for the task
  4. Resume if needed: claude --resume <name>

Troubleshooting

Session Not Found

If a named session isn't appearing in /resume:

  • Check for typos in the name
  • Sessions may expire after extended inactivity
  • Use /resume screen to browse available sessions
Duplicate Sessions in VS Code

If you see duplicate session entries when resuming in VS Code:

  • Claude Code 2.1.38+: Fixed: resume now correctly reuses the existing session without creating duplicates
  • Older versions: Ignore the duplicate entries; they point to the same underlying session
Lost Context After Resume

If context seems incomplete or resume is slow:

  • Claude Code 2.1.30+: 68% memory reduction for --resume via stat-based session loading with progressive enrichment, especially impactful for users with many sessions. Also fixes hangs when resuming sessions with corrupted transcript files (parentUuid cycles).
  • Claude Code 2.1.29+: Fixed slow startup when resuming sessions with many once: true hooks: saved_hook_context loading is now optimized
  • Claude Code 2.1.21+: Fixed API errors when resuming sessions interrupted during tool execution: previously these sessions could fail to resume entirely
  • Claude Code 2.1.20+: Session compaction/resume is now fixed: resume correctly loads the compact summary instead of full history
  • Use /catchup to refresh git state
  • Use /debug (Claude Code 2.1.30+) for session troubleshooting diagnostics
  • Re-run Skill(sanctum:git-workspace-review) if needed
  • If on older versions: resumed sessions may reload uncompacted history, increasing context usage unexpectedly

macOS Orphaned Processes (Claude Code 2.1.46+)

Previously, disconnecting from a terminal on macOS could leave orphaned Claude Code processes running. This is now fixed in 2.1.46+. If you encounter stale CC processes on older versions, manually check and kill them:

bash
# Find orphaned claude processes
ps aux | grep -i claude | grep -v grep
7. Automatic Memory (Claude Code 2.1.32+)

Claude now automatically records and recalls memories as it works. Session summaries, key results, and work logs are captured implicitly and recalled in future sessions. This provides passive cross-session continuity without manual checkpoint management.

  • No action required: Memory recording is automatic on first-party Anthropic API
  • Complements named sessions: Automatic memory handles implicit continuity; named sessions provide explicit organization
  • Token overhead: Recalled memories add to baseline context, factor this into MECW budgets
8. Agent Persistence on Resume (Claude Code 2.1.32+)

--resume now re-uses the --agent value from the previous conversation by default. Agent-specific workflows that are resumed will continue with the same agent configuration without needing to re-specify it.

# Start with a specific agent
claude --agent my-agent

# Resume later — my-agent is automatically used
claude --resume

  • /clear - Start fresh session
  • Skill(sanctum:git-workspace-review) - Capture repo context

Exit Criteria

  • Session named via /rename using a hyphenated descriptive name matching one of the documented patterns (e.g. debugging-*, feature-*, pr-review-*)
  • Session resumes via claude --resume <name> without loss of prior context (verified by presence of earlier conversation)
  • If a session name is not found on resume, the error is surfaced with troubleshooting steps (check typos, session expiry)
  • For PR-linked sessions (Claude Code 2.1.27+), claude --from-pr <number> correctly reopens the session associated with that PR
  • If session context seems incomplete after resume, Skill(sanctum: git-workspace-review) is re-run and its output confirms current repo state
