session-list is a skill for Claude Code, Codex from apappascs/claude-code-sessions. It costs 52 tokens per session (285 once invoked), scanned A, original, MIT.

A list view of Claude Code sessions, either for one project or across all projects. Sessions can be sorted by recent activity, file size, or duration.

In plain words
What is it for?
Use it to review session history, count or browse sessions, find long sessions, or reopen work from a particular project.
Why use it?

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

session-list 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 3d ago.

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.

What it actually says

Session List

List all sessions, optionally filtered by project and sorted.

Step 1: Run the listing script

bun run ${CLAUDE_PLUGIN_ROOT}/lib/session-store.ts list --limit 20

To filter by project:

bun run ${CLAUDE_PLUGIN_ROOT}/lib/session-store.ts list --project "<filter>" --limit 20

To sort by size or duration instead of recency:

bun run ${CLAUDE_PLUGIN_ROOT}/lib/session-store.ts list --sort size --limit 20

Step 2: Present results

The script outputs a JSON array. Present as a markdown table:

# Session ID Project Date Messages Duration Size

Highlight the current session if it matches the working directory. Show the resume command: claude --resume <session-id>.

If the user asks for more detail on a specific session, use /session-stats <session-id>.

Changes

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.
