session-search

session-search is a skill for Claude Code, Codex from pchalasani/claude-code-tools. It costs 33 tokens per session (657 once invoked), scanned C, original, MIT.

A command-line workflow for searching previous coding-agent sessions for decisions, code patterns, or completed work.

In plain words
What is it for?
Use it to search session records, inspect up to three relevant files, and summarize the findings with session references.
Why use it?
It helps recover specific information from older sessions when the current agent cannot use separate helper agents.

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 C, and why

session-search scanned grade C with 2 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.

How it starts

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

If you are Claude Code: Do NOT use this skill directly. Use the session-searcher subagent via the Task tool instead - it handles this more efficiently without polluting your context.

Search and find previous code agent sessions (Claude-Code or Codex-CLI) for specific work, decisions, or code patterns.

Workflow

  1. Understand the query: Identify what the user is looking for (code patterns, decisions, specific work, design direction)
  2. Search with aichat: Run aichat search --json -n 10 "[query]" (use -g "project" to filter by project)
  3. Parse results: Use jq to extract fields from JSONL output (session_id, project, created, snippet, file_path)
  4. Deep dive if needed: Read session files at ~/.claude/projects/*/[session-id].jsonl (max 3 files)
  5. Summarize: Return a focused summary with key findings and references

Run aichat search --help to see all options (date filters, branch filters, etc.) and JSONL field names.

Output Format

Return a concise summary containing:

  1. Key Findings: 2-3 bullet points answering the query
  2. Relevant Sessions: Session IDs and dates for reference
  3. Specific Content: Code snippets or quotes if directly relevant

Format as clean markdown, not raw JSON.

Example

Query: "Find sessions where we discussed authentication design"

aichat search --json -n 10 "authentication design"

Summary:

  • Session abc123 (Dec 10): Discussed JWT vs session-based auth, decided on JWT
  • Session def456 (Dec 8): Implemented refresh token rotation pattern

Constraints

  • ALWAYS use --json flag with aichat search (otherwise it spawns interactive UI)
  • NEVER return raw JSON output to the user - summarize and distill findings
  • NEVER read more than 3 session files per query
  • If no results found, suggest alternative search terms
  • ONLY report information directly observed in files - never infer or extrapolate

Error Handling

If aichat search command fails or is not found, ask user to install:

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.

session-search is a skill published in the GitHub repository pchalasani/claude-code-tools (1,989 stars, last pushed 4d ago), licensed MIT. It adds 33 tokens to every session and 657 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls).
