claude-session-manager

claude-session-manager is a skill for Claude Code, Codex from sugarforever/01coder-agent-skills. It costs 94 tokens per session (1,511 once invoked), scanned A, original, MIT.

A manager for local Claude Code session transcripts, which are saved records of Claude Code conversations and tool calls. It can find sessions, organize them into Markdown files, inspect archives, and summarize activity.

In plain words
What is it for?
Use it to list candidate sessions, export all or selected sessions, inspect archived transcripts, and review conversation and tool-call history.
Why use it?
It avoids manually searching raw JSONL files stored across Claude Code project folders. It helps turn past sessions into readable, organized records.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

claude-session-manager 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/manage_claude_sessions.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Claude Session Manager

Overview

Claude Code stores session transcripts as JSONL files under ~/.claude/projects/<project-key>/<session-id>.jsonl. Use the bundled manager to list candidates or export sessions into project-organized Markdown transcripts with a digest, a clean user/Claude conversation, and linked tool-call details.

Default output folder: ~/.claude/session-markdown. Tell the user before exporting there, and mention any custom output folder they requested.

Quick Start

Let the user's wording choose the mode when it is clear; otherwise ask them to choose before exporting:

  • Full mode: export all matching sessions. Use this for archive, backup, broad search, or "convert all sessions" requests.
  • Specific mode: list candidate sessions first, ask the user to pick one, then export only that session.

Run from any directory:

python3 /path/to/claude-session-manager/scripts/manage_claude_sessions.py

Equivalent explicit form:

python3 /path/to/claude-session-manager/scripts/manage_claude_sessions.py \
  --source ~/.claude/projects \
  --output ~/.claude/session-markdown

Useful options:

  • --mode full: export all matching sessions. This is the default.
  • --mode specific --list-candidates: print a numbered candidate table and do not export.
  • --mode specific --pick N: export the Nth candidate from the same filtered candidate list.
  • --project <text>: only export project folders whose key contains this text.
  • --session <text>: only export sessions whose id or filename contains this text.
  • --since YYYY-MM-DD: only export sessions modified on or after this date.
  • --limit N: export the N most recently modified matching sessions.
  • --include-tool-details-inline: embed full tool inputs/results in the main session Markdown. By default, the main transcript keeps compact collapsible tool summaries and links full payloads through the sidecar file.

Specific Mode Candidate Flow

Use this flow when the user wants one session, is unsure which session they need, or asks to inspect recent sessions before converting.

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.
