session-search

session-search is a skill for Claude Code, Codex from apappascs/claude-code-sessions. It costs 68 tokens per session (310 once invoked), scanned A, original, MIT.

A search tool for Claude Code sessions across projects. It finds matching words, topics, or regular-expression patterns in previous conversations.

In plain words
What is it for?
Use it to find past decisions, locate earlier work, search for a phrase, or identify a session you can resume.
Why use it?
It saves you from opening sessions one by one when you remember a detail but not where it was discussed. Results can be narrowed by project or date.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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-search 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 4d 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

Search across all Claude Code sessions by keyword or regex.

bun run ${CLAUDE_PLUGIN_ROOT}/lib/session-store.ts search "<query>" --limit 20 --context 1

To filter by project:

bun run ${CLAUDE_PLUGIN_ROOT}/lib/session-store.ts search "<query>" --project "<filter>" --limit 20 --context 1

To filter by date:

bun run ${CLAUDE_PLUGIN_ROOT}/lib/session-store.ts search "<query>" --since "2026-04-01" --limit 20

Step 2: Present results

The script outputs newline-delimited JSON (one match per line). Group results by session and present:

  • Session ID and project as headers
  • Matching text with timestamp
  • Context (lines before/after) if available
  • Resume command: claude --resume <session-id>

If no results, suggest broadening the search or trying different keywords.

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.
