What is session-search?

A search tool for finding past Claude Code conversation transcripts using natural-language queries. It can match related words and concepts, not just exact terms.

Use it to find earlier sessions about a topic, problem, project, or task.

It removes the need to remember which conversation contained a decision, debugging session, research task, or piece of work.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00050	$0.00501
Opus 5	$0.00025	$0.00251
Sonnet 5	$0.00010	$0.00100
Haiku 4.5	$0.00005	$0.00050

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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/search.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.

What it actually says

Session Search

Search Claude Code session transcripts by combining keyword pre-filtering with semantic evaluation. Finds previous sessions about specific topics, debugging conversations, research tasks, or any past work.

Workflow

Step 1: Run the search script

Execute scripts/search.py with the user's query:

python3 scripts/search.py "<query>" [max_results] [max_age_days]

query (required): Natural language search query
max_results (optional, default 10): Maximum results to return
max_age_days (optional, default 90): How far back to search

The script performs keyword pre-filtering across all sessions, then extracts meaningful excerpts from top candidates. Output contains a SESSIONS_DATA JSON block.

Step 2: Evaluate results semantically

After receiving the script output, evaluate each session's relevance to the query. Consider:

Synonym matching: "bug" matches "error", "issue", "problem", "fix"
Related concepts: "debugging" matches sessions with test failures or error messages
Tool patterns: "refactoring" matches Edit-heavy sessions
Domain context: "obsidian" matches vault-related work

Assign a relevance score (0-10) to each session based on excerpt content and query intent.

Step 3: Present results

Display the top results (up to max_results) sorted by relevance, formatted as:

### [Relevance: N/10] Project — Date
Summary of what the session was about (1-2 sentences based on excerpts)
`claude --resume <session-id>`

If no relevant results are found, report that and suggest alternative queries.

Session Storage

Sessions are stored as JSONL files in ~/.claude/projects/. Each file contains events with user/assistant messages and tool calls. The search script handles file discovery and text extraction automatically.

Customization

To search older sessions or get more results:

/session-search "query" 20 180

(20 results, 180 days lookback)

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

session-search is a skill published in the GitHub repository glebis/claude-skills (374 stars, last pushed 8d ago), licensed MIT. It adds 50 tokens to every session and 501 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
